Moving to Rialto, CA?
Here are the local rules you need to know before you unpack.
Every city has its own set of local ordinances that go beyond state and federal law. From when you can mow your lawn to whether you can park your RV in the driveway, these rules affect daily life in ways most people do not expect. This guide covers the key ordinances in Rialto across 18 categories and 103 specific rules we track.
๐ Noise OrdinancesFull noise ordinances guide โ
Noise rules affect everything from weekend parties to lawn care schedules. Quiet hours, construction restrictions, and barking dog limits vary widely between cities.
Amplified Music & Events
Heavy RestrictionsRialto Municipal Code Section 9.50.030(A)(4) bans music or sound amplification equipment that is plainly audible across property lines, through shared walls, at 50 feet from 8:00 a.m. to 10:00 p.m., or at 25 feet from 10:00 p.m. to 8:00 a.m.
Outdoor Music
Some RestrictionsAmplified outdoor music in Rialto is regulated under Municipal Code Title 9 Ch. 9.50 (Noise Control). Sound must not exceed the receiving-property decibel limit and is generally prohibited from being plainly audible at a residential property line between 10:00 pm and 7:00 am. Commercial venues and special events require a permit; alcohol-served outdoor entertainment also triggers ABC conditional licensing.
Aircraft Noise
Few RestrictionsRialto's noise ordinance exempts aircraft noise, which is measured instead under the General Plan noise element using the CNEL method. The city-owned Rialto Municipal Airport has been closed to air traffic, so no active airport noise sources remain within the city.
Vehicle Noise
Heavy RestrictionsRialto Municipal Code Section 9.50.040 makes it a misdemeanor to play a car stereo or other in-vehicle sound device plainly audible at 50 feet, or beyond the property line on private property. Police may immediately confiscate the sound components or even the vehicle.
Decibel Limits
Some RestrictionsRialto Municipal Code Title 9, Chapter 9.50 (Noise Control) establishes exterior noise limits measured at the property line of the impacted receiving land use. Limits vary by zoning of the receptor (residential strictest) and time of day (7am-10pm daytime vs 10pm-7am nighttime). Construction activity is separately regulated under the same chapter.
Industrial Noise
Some RestrictionsSounds necessary and incidental to permitted uses in Rialto's commercial and industrial zones are exempt from the noise ordinance, but Renaissance Specific Plan standards bar operations next to residential areas from 11:00 p.m. to 6:00 a.m. and loading from 10:00 p.m. to 6:00 a.m.
Quiet Hours
Some RestrictionsRialto Municipal Code Section 9.50.050 makes it unlawful to operate power tools, loading equipment, compressors, heavy trucks, and similar noisy gear outside 7:00 a.m. to 8:00 p.m. in all zones. Amplified sound faces a tighter plainly-audible standard between 10:00 p.m. and 8:00 a.m.
Construction Hours
Heavy RestrictionsRialto Municipal Code Section 9.50.070 sets seasonal construction hours: October-April weekdays 7:00 a.m.-5:30 p.m., May-September weekdays 6:00 a.m.-7:00 p.m., Saturdays 8:00 a.m.-5:00 p.m. year-round, and no construction at all on Sundays or state holidays.
Leaf Blower Rules
Some RestrictionsRialto restricts gasoline and electric leaf blowers to the hours of 7:00 a.m. to 8:00 p.m. in all zones under Municipal Code Section 9.50.050(D). The city does not ban gas-powered blowers outright or set decibel limits for them.
Barking Dogs
Some RestrictionsRialto prohibits noisy animals: city guidance states animals cannot disturb the peace and quiet of neighbors, and noisy fowl such as roosters are banned outright. Animal noise complaints are handled under Title 6 of the municipal code, not the general noise ordinance.
๐ Short-Term RentalsFull short-term rentals guide โ
If you plan to rent out your home on Airbnb or VRBO - even occasionally - you need to know the local STR rules before listing.
Registration Rules
Heavy RestrictionsRialto has not established a short-term rental registry, certificate, or annual permit program in its municipal code. There is no STR-specific application, fee schedule, or inspection process in Title 5 or Title 18, so the only formal city registration available to an STR operator is a general business license under Chapter 5.04.
Night Caps
Few RestrictionsRialto does not impose an annual cap on the number of nights a host may rent short-term. Unlike Los Angeles (120 nights unhosted), San Francisco (90 nights unhosted), or Santa Monica (no whole-home STRs allowed), Rialto MC contains no night-cap provision. A host with a Rental Income Property business license under Title 5 and current TOT compliance under Chapter 3.08 (9% rate, transient = โค30 consecutive days) can theoretically operate 365 nights/year. ADUs and JADUs remain capped at 30+ day minimum terms by Cal. Gov. Code ยง65852.2(a)(6).
Primary-Residence-Only Rule
Heavy RestrictionsRialto's municipal code does not contain a short-term rental ordinance and therefore does not distinguish between primary-residence (hosted) STRs and non-owner-occupied (whole-home, investor) STRs. Because Title 18 zoning does not list STRs as a permitted use at all, there is no primary-residence exception that legalizes any class of operator.
Extended Home Share
Some RestrictionsRentals of 30 days or longer are residential tenancies under California law rather than transient occupancy. They are governed by the state Civil Code (Cal. Civ. Code ยง1940 et seq. tenancies, ยง1946 termination) and AB 1482 statewide rent cap (Civ. Code ยง1947.12), not by any local STR rule. Rialto has not adopted a separate extended home-share permit.
Insurance Requirements
Few RestrictionsRialto does not impose a minimum liability-insurance requirement for short-term rental operators because the city has no STR-specific permit ordinance. STR-permit cities like Palm Springs and Santa Monica condition permits on $500K-$1M general liability coverage; Rialto's Rental Income Property business license under Title 5 does not. Hosts should still verify coverage because standard homeowner ISO HO-3 policies typically exclude 'business pursuits' losses, and Airbnb's $1M Host Liability Insurance / AirCover does not substitute for proper landlord/commercial policy.
Permit Requirements
Some RestrictionsRialto has no short-term-rental-specific permit ordinance, but anyone renting rooms or dwellings on a transient basis must obtain a City business license under the Rental Income Property classification (Rialto Municipal Code Chapter 5.70) and register with the tax administrator for a Transient Occupancy Registration Certificate under RMC 3.08.060.
Host Presence Rule
Heavy RestrictionsRialto has no short-term rental ordinance and therefore no host-presence (on-site host) requirement, no off-site local contact rule, and no 24/7 emergency contact mandate specific to STRs. Because STRs are not a recognized land use in Title 18, the code provides no framework distinguishing hosted from unhosted operation.
Parking Rules
Some RestrictionsRialto does not impose STR-specific guest-parking minimums because the city has no STR ordinance. Hosts must rely on the general framework: Title 18 Zoning sets off-street parking minimums for the underlying dwelling (typically 2 covered spaces per single-family home in Rialto's R-1 zones), Title 10 Vehicles and Traffic governs on-street parking (including the 72-hour vehicle-storage rule under Cal. Veh. Code ยง22651(k)), and oversize/RV parking is restricted near the Rialto Municipal Airport (L67) AIA overlay and on residential streets per Title 10 posted-zone rules.
Occupancy Limits
Few RestrictionsNo Rialto-specific ordinance directly addresses short-term rental occupancy limits; California state default applies. General habitability and occupancy standards flow from the State Housing Law (Health and Safety Code Sec. 17922), which adopts Uniform Housing Code requirements.
Taxes & Fees
Some RestrictionsRialto imposes a 9% Transient Occupancy Tax (TOT) on stays of 30 consecutive days or less under Rialto Municipal Code Chapter 3.08 (effective January 18, 1991, per the State Controller's annual TOT report). The TOT applies to hotels, motels, and short-term residential rentals alike. Rialto has no STR-specific permit chapter โ short-term hosts must obtain a standard Rental Income Property business license under Title 5 from the Business Licensing Division (909-820-2517) and remit TOT directly to the city. Airbnb does NOT have a TOT collection agreement with Rialto, so hosts must self-report.
Noise Rules
Some RestrictionsRialto has no STR-tailored quiet-hours or 'one-strike' permit rule because the city lacks an STR ordinance. All noise complaints โ including those at vacation rentals โ are enforced under Rialto MC Chapter 9.50 (Noise Control), which prohibits loud, unreasonable, or 'plainly audible' sound (the rhythmic bass component of music alone is sufficient evidence). Chapter 9.50 is administered jointly by Rialto Police and the Department of Development Services Code Enforcement Division. Construction noise has seasonal time windows (Oct 1โApr 30 vs May 1โSep 30); residential noise complaints follow the general nuisance standard.
๐ฅ Fire RegulationsFull fire regulations guide โ
Fire pit rules, fireworks restrictions, and brush clearance requirements are especially important if you are coming from a state with different fire risk profiles.
Brush Clearance
Some RestrictionsRialto runs citywide weed abatement inspections twice a year, in April and October. Weeds or dry grass over 4 inches must be cleared, flammable vegetation removed at least 30 feet around structures, and unabated lots are cleared by a city contractor with the cost liened against the property.
Propane Storage
Some RestrictionsPropane (LPG) storage in Rialto is governed by Cal. Fire Code Chapter 61 (Liquefied Petroleum Gases), adopted by reference under Rialto Mun. Code Ch. 15.28. Residential propane cylinders โค2.5 lb. propane each are essentially unregulated; storage beyond that triggers permit, setback, and placement rules. Commercial/industrial bulk storage above 125 gal. requires a Rialto Fire operational permit and engineered separation distances.
Outdoor Burning
Heavy RestrictionsRialto's local fire code amendment flatly prohibits open burning anywhere in the city, and South Coast AQMD Rule 444 separately bans residential burning of waste throughout the air basin. Only contained cooking and warming fires using clean fuels are exempt.
Wildfire Zones
Some RestrictionsRialto adopted the State Fire Marshal's updated 2025 fire hazard severity zone maps, which place parts of the city in Moderate, High, or Very High zones. Very High zone properties must maintain 100 feet of defensible space and meet home-hardening and disclosure rules.
Fireworks
Some RestrictionsRialto is one of the few San Bernardino County cities that allows state-approved safe and sane fireworks. Municipal Code section 5.20.010 limits sale and discharge to the window from noon June 28 through midnight July 6, and all dangerous fireworks are banned.
Backyard Fires
Some RestrictionsBackyard fires in Rialto are legal only as contained cooking or warming fires burning clean fuels such as propane, natural gas, charcoal, or untreated wood. Burning rubbish, yard waste, or debris is residential burning, which is prohibited by both the city fire code and SCAQMD Rule 444.
Fire Pit Rules
Some RestrictionsGas and propane fire pits and charcoal barbecues are exempt from regional burn rules in Rialto. Wood-burning fire pits must qualify as recreational fires under the California Fire Code: no more than 3 feet across and 2 feet high, kept 25 feet from structures, and constantly attended.
๐ Parking RulesFull parking rules guide โ
Parking rules catch more new residents off guard than almost any other ordinance. RV storage, overnight parking bans, and driveway regulations vary significantly.
Commercial Vehicle Restrictions
Heavy RestrictionsRialto prohibits parking or storing commercial vehicles with a one-ton or greater rated carrying capacity or over 10,000 pounds gross vehicle weight both in residential zones (RMC 10.28.291) and on all city streets (RMC 10.28.293), with narrow exceptions for active deliveries and permitted construction.
RV & Boat Parking
Some RestrictionsRialto prohibits parking or storing RVs, campers, boats and trailers on lawns, landscaped areas or other unpaved surfaces in residential zones. Recreational items visible to the public must be enclosed behind a solid fence or block wall at least five feet high (RMC 10.28.292).
Overnight Parking
Few RestrictionsNo Rialto-specific ordinance imposes a citywide overnight parking ban on passenger vehicles; California state defaults apply. Posted no-parking areas, the 72-hour rule and the round-the-clock commercial-vehicle street ban still limit where vehicles can sit overnight.
Street Parking Limits
Some RestrictionsRialto Municipal Code Chapter 10.28 governs on-street parking. No vehicle may be parked on any street or alley for more than 72 consecutive hours, and the police department may tow violators under California Vehicle Code Section 22651(k).
EV Charging
Some RestrictionsRialto designates stalls in city-owned off-street parking facilities exclusively for vehicles connected for electric charging (RMC 10.28.174, adopted 2021 under California Vehicle Code Section 22511). Vehicles parked in posted EV stalls while not connected for charging can be towed.
Abandoned Vehicles
Heavy RestrictionsKeeping abandoned, wrecked, dismantled or inoperative vehicles or parts on any Rialto premises is unlawful and a misdemeanor (RMC 9.26.030). The city may also abate such vehicles as public nuisances after a ten-day notice, assessing removal costs against the landowner.
Driveway Rules
Some RestrictionsOn Rialto residential property, vehicles must be kept on the driveway or in the garage. Parking on front lawns, landscaped areas or any non-paved surface is prohibited (RMC 10.28.292), as is parking on vacant or undeveloped land (RMC 18.58.020).
๐งฑ Fence RegulationsFull fence regulations guide โ
Planning to put up a fence? Height limits, material restrictions, and permit requirements differ by city - and sometimes by which side of the property the fence sits on.
Retaining Walls
Some RestrictionsRialto's standard block wall design may not retain any earth, so retaining walls need their own building permit and engineered design through Building and Safety, with footing, bond beam, and final inspections before approval.
Neighbor Fence Rules
Some RestrictionsWalls crossing a Rialto property line require written, possibly notarized, permission from the adjacent owner plus a signed block wall or fence agreement. California Civil Code Section 841 presumes neighbors split boundary fence costs equally after 30 days written notice.
Approved Materials
Some RestrictionsRialto Code ยง18.61.170 (Fences and Walls) within the Chapter 18.61 Design Guidelines governs fence material standards. Standard residential materials (wood, masonry block, wrought iron, vinyl) are allowed; barbed wire, razor wire, and electrified fences are restricted to specified non-residential contexts under the zoning code.
Material Restrictions
Heavy RestrictionsBarbed wire and razor wire are prohibited in all Rialto residential zones, and no sharp points may top any fence under six feet. City design standards also require decorative, durable materials and restrict undersized concrete block.
Height Limits
Some RestrictionsRialto caps fences, hedges, and walls at six feet in required side and rear yards. In the required front yard setback, solid fences and walls max out at three and a half feet, though hedges, chain link, wrought iron, and block pilasters may reach six feet.
Permit Requirements
Some RestrictionsRialto requires permits for walls taller than 42 inches and building permits for all masonry and retaining walls. Block walls get three city inspections, and walls crossing a property line need a signed fence agreement.
Pool Barriers
Heavy RestrictionsEvery Rialto pool, spa, or hot tub holding water over 18 inches deep must be enclosed by a barrier at least 60 inches high with self-closing, self-latching gates, installed and approved before the pool is plastered or filled.
๐ Animal OrdinancesFull animal ordinances guide โ
Pet owners and aspiring chicken keepers should check local animal ordinances before signing a lease or closing on a home.
Dog Leash Laws
Some RestrictionsRialto Municipal Code Title 6 (Animals) requires dogs to be restrained on a leash when off the owner's property and prohibits any dog from running at large in the city. Owners are strictly liable for control of the animal in public rights-of-way, parks, and on other private property.
Wildlife Feeding
Some RestrictionsRialto has no standalone municipal ordinance banning wildlife feeding, but feeding deer, coyotes, raccoons and other wild mammals is regulated statewide under California Fish & Game Code ยง 251.1 (harassment) and 14 CCR ยง 251.3, which prohibits intentionally feeding big game mammals. Attracting wildlife that becomes a public nuisance is independently abatable under Rialto Municipal Code Title 6 / Title 8 (Health & Sanitation).
Exotic Pets
Heavy RestrictionsExotic and restricted species are primarily controlled by California state law, not local Rialto ordinance. Cal. Fish & Game Code ยง 2118 and 14 CCR ยง 671 prohibit private possession of most non-domesticated species (big cats, primates, venomous reptiles, ferrets, hedgehogs, sugar gliders) without a CDFW restricted-species permit. Rialto Title 6 reinforces this by prohibiting wild / dangerous animals as a public nuisance.
Animal Hoarding
Heavy RestrictionsRialto does not have a standalone animal-hoarding chapter; cases are charged under California Penal Code ยง 597 (animal cruelty) and ยง 597f (failure to care), combined with Rialto Municipal Code Title 6 (excess animals/public nuisance) and Title 8 (Health & Sanitation). Convicted hoarders are barred from owning animals for 5 years (misdemeanor) or 10 years (felony) under Cal. Penal Code ยง 597.9.
Chickens & Livestock
Heavy RestrictionsRoosters and other noisy fowl are prohibited as a public nuisance, and barnyard animals such as pigs, goats, and sheep are not allowed in Rialto's residential zones. Poultry and livestock keeping is permitted only in the A-1 agricultural zone, subject to setbacks and per-acre limits.
Pet Limits
Some RestrictionsRialto caps household pets at four weaned dogs and cats combined, and no more than three of them may be dogs. The limit appears in Rialto Municipal Code Section 6.04.240 and the residential zoning rules in Section 18.10.020.
Beekeeping
Heavy RestrictionsBees are a permitted use only in Rialto's A-1 agricultural zone, where hives must be at least 200 feet from any dwelling other than the beekeeper's own. Residential zone permitted-use lists do not include bees.
Breed Restrictions
Few RestrictionsRialto's municipal code contains no breed-specific restrictions; its dangerous-dog rules in Chapter 6.05 apply based on a dog's behavior. California state law forbids cities from declaring any breed dangerous or vicious and limits breed-specific ordinances to spay/neuter and breeding programs.
๐ฟ Landscaping RulesFull landscaping rules guide โ
From grass height limits to tree removal permits, landscaping rules can surprise new homeowners, especially in drought-prone areas with water restrictions.
Grass Height Limits
Heavy RestrictionsLawns taller than six inches, or untrimmed grass encroaching more than two inches over sidewalks, are public nuisances under Rialto's property maintenance chapter. Vacant-lot weeds or dry grass over four inches are cited through the fire department's weed-abatement program.
Weed Ordinances
Heavy RestrictionsRialto's Fire Prevention Division runs weed abatement twice a year, inspecting vacant lots starting in April and October. Weeds or dry grass over four inches, noxious weeds, trash, or overgrown vegetation must be abated; unabated parcels are cleared by a city contractor and liened.
Tree Trimming
Some RestrictionsRialto controls planting, pruning, and removal of trees in streets and parkways. Abutting owners must water street trees, keep parkway plants neat, and trim private vegetation overhanging sidewalks or streets; fire standards require branches trimmed eight feet from the ground.
Native Plants
Some RestrictionsRialto's water conservation chapter requires native or water-conserving plant species in landscaping, with landscape plans approved by the city, and lawns minimized in commercial, hotel, condominium, and high-density housing developments. State MWELO efficiency standards apply to larger new landscape projects.
Rainwater Harvesting
Few RestrictionsRainwater capture is legal and encouraged in California under the Rainwater Capture Act of 2012 (AB 1750). Rialto requires no permit for rain barrels up to 5,000 gallons used outdoors. Larger cisterns and any indoor/potable use require plumbing permits and backflow protection per the California Plumbing Code.
Artificial Turf
Few RestrictionsCalifornia Government Code ยง53087.7 (AB 349, 2015) bars cities and HOAs from prohibiting artificial turf on residential property. Rialto allows synthetic grass in residential yards subject to general landscape design standards and MWELO permeability requirements.
Tree Removal & Heritage Trees
Some RestrictionsRemoving a street or parkway tree requires prior written permission from the public services director, and the city's published criteria allow removal only of dead, hazardous, damaging, or incompatible trees; healthy trees are not approved for removal.
Water Restrictions
Heavy RestrictionsRialto Municipal Code Chapter 12.20 sets four escalating water-conservation stages. Stage 1 permanently bans runoff, washing pavement, and non-recirculating fountains; the Stage 2 Water Alert adopted in 2016 limits sprinkler irrigation to four days per week, ten minutes per station.
๐ผ Home BusinessFull home business guide โ
Working from home is common, but running a business from home often requires permits and must comply with zoning restrictions on customer traffic and signage.
Signage Rules
Heavy RestrictionsRialto bans all on-site display and advertising for home occupations except a single non-illuminated nameplate no larger than one square foot. Advertising that identifies the home's street address is also prohibited, except in telephone directories and on business cards.
Zoning Restrictions
Some RestrictionsHome occupations are permitted in every Rialto residential zone district with a permit (RMC 5.68.030), but the business must stay incidental to the residence: it may occupy no more than 25 percent of the home's habitable floor area and must be conducted entirely inside the dwelling.
Cottage Food Operations
Some RestrictionsCalifornia law bars Rialto from prohibiting cottage food operations in residential dwellings (Gov. Code 51035). Home food businesses register with San Bernardino County Environmental Health Services - Class A (direct sales) by registration, Class B (direct and indirect sales) by health permit - and also need City of Rialto planning approval.
Customer Traffic Restrictions
Some RestrictionsA Rialto home occupation may not significantly increase neighborhood traffic, and more than eight patrons in any 24-hour period is conclusively deemed a violation. Only one non-resident employee or contractor may be on site at a time.
Home Daycare
Few RestrictionsState law makes small (up to 8 children) and large (7 to 14 children) family daycare homes a residential use by right, and Rialto cannot impose a business license, fee, or tax on them. RMC 5.68.040(D) expressly exempts state-licensed child care from the city's home occupation permit requirement.
Home Occupation Permits
Some RestrictionsRialto requires home-based businesses to obtain both a Home Occupation Permit from the Planning Division and a city business license. Under Rialto Municipal Code 5.68.040, no business license may be issued for a home occupation until a valid home occupation permit has been issued.
๐ Swimming Pools & SpasFull swimming pools & spas guide โ
Pool ownership comes with safety fencing requirements, permit obligations, and drainage rules that vary by jurisdiction.
Safety Rules
Some RestrictionsWhen a house wall forms part of the pool barrier in Rialto, every door with direct pool access needs either a self-latching device mounted at least 54 inches high or a UL 2017-listed alarm that sounds within 7 seconds. State law separately requires two of seven drowning prevention features on any newly permitted or remodeled residential pool.
Above-Ground Pools
Some RestrictionsAbove-ground, portable, inflatable, and collapsible pools holding water over 18 inches deep are subject to the same 5-foot barrier fencing rules as in-ground pools in Rialto. The pool's own walls can serve as the barrier only if they are at least 5 feet high and meet all barrier standards, with ladders that lock, are removable, or are fenced.
Pool Permits
Some RestrictionsBuilding a pool or spa in Rialto requires a building permit through the city's Online Permit Center, with plans that show compliance with the pool fencing chapter, and the pool cannot be filled until fences and gates pass inspection. State law adds that any new or remodeled residential pool must include at least two of seven drowning prevention safety features verified at final inspection.
Hot Tub Rules
Some RestrictionsSpas and hot tubs in Rialto fall under the same pool rules, but self-contained spas and hot tubs with listed locking safety covers are exempt from the barrier fencing requirement. Without a locking cover, the 5-foot barrier rules apply.
Fencing Requirements
Heavy RestrictionsRialto requires every swimming pool to be surrounded by a protective barrier fence or wall at least 60 inches (5 feet) high with self-closing, self-latching gates, and the barrier must be inspected and approved before the pool is plastered or filled with water. The rule covers in-ground, above-ground, portable, and collapsible pools, plus garden ponds, spas, hot tubs, wading pools, and fountains holding water over 18 inches deep.
๐๏ธ Accessory StructuresFull accessory structures guide โ
Thinking about an ADU, shed, or garage conversion? Local rules on accessory structures have changed rapidly in recent years, especially in California.
Tiny Homes
Some RestrictionsTiny homes in Rialto are regulated either as ADUs under California Government Code ยง65852.2 (state ADU law) and Rialto Municipal Code Title 18, or as RVs/manufactured housing under state HCD rules. Permanent tiny homes on foundations qualify as ADUs and benefit from California's ministerial-approval preemption.
ADU Rental Restrictions
Some RestrictionsRialto cannot ban ADU rentals, but state law (Cal. Gov. Code ยง66314(a)(6)) prohibits renting an ADU for less than 30 days. Long-term rentals are permitted by right; short-term vacation rentals in ADUs are not allowed under state law statewide.
ADU Impact Fees
Few RestrictionsADUs under 750 sq ft are exempt from all impact fees in Rialto by force of state law (Cal. Gov. Code ยง66314(f)(3)). ADUs 750 sq ft or larger may be charged impact fees only proportionally to the primary dwelling's square footage. School-district fees are separately governed.
ADU Permits
Some RestrictionsADU permits are issued by the Rialto Building & Safety Division (150 S Palm Ave). State law (Gov. Code ยง66317) requires the city to act on a complete ADU application within 60 days, ministerially, with no discretionary hearing. Plans must comply with the California Building Standards Code (effective 2025 edition as of Jan. 1, 2026) and RMC Title 15.
Garage Conversions
Some RestrictionsRialto ministerially approves conversion of an existing, legally permitted garage into an ADU with no new setbacks and no replacement parking, but the garage door must be replaced with windows or doors matching the home. Unpermitted units built before 2020 can be legalized under AB 2533.
ADU Owner Occupancy
Few RestrictionsRialto cannot impose an owner-occupancy requirement on ADUs permitted between Jan. 1, 2020 and Jan. 1, 2025 (Cal. Gov. Code ยง66314(a)(6)). Owner-occupancy is required for Junior ADUs (JADUs) under Cal. Gov. Code ยง66333 โ owner must live in either the main house or the JADU.
Shed Rules
Some RestrictionsRialto lists accessory buildings and gazebos among work requiring a building permit. Under Municipal Code Section 18.52.030, detached accessory buildings may occupy at most 25 percent of the rear yard and need 10 feet of separation from the house if over 120 square feet.
ADU Rules
Some RestrictionsRialto allows one ADU plus one junior ADU per single-family lot with ministerial approval within 60 days under Rialto Municipal Code Section 18.10.070. Detached ADUs are limited to 16 feet in height, four-foot side and rear setbacks, and 1,200 square feet maximum.
Carport Rules
Some RestrictionsRialto's Building and Safety standard bars using a residential patio cover as a carport or garage, and R-1 zoning limits private garages to a three-automobile capacity with an 18-foot setback when a side-yard garage opens onto the street.
๐ Environmental RulesFull environmental rules guide โ
Stormwater Management
Heavy RestrictionsRialto is a co-permittee on the San Bernardino County MS4 NPDES Permit issued by the Santa Ana Regional Water Quality Control Board (Order R8-2010-0036, NPDES No. CAS618036) and enforces stormwater quality controls under Title 13 (Public Services) of the Municipal Code. All non-stormwater discharges to the storm drain (including wash water, paint, oil, and sediment) are prohibited, and construction sites โฅ1 acre require coverage under the Statewide Construction General Permit and a SWPPP.
Grading & Drainage
Some RestrictionsRialto regulates grading and on-site drainage through Title 15 (Buildings and Construction), which adopts California Building Code Appendix J. A grading permit is generally required for any earthwork exceeding 50 cubic yards, any cut or fill over 5 feet, or work that alters established drainage patterns. Drainage must convey runoff to an approved point of disposal without discharging concentrated flows onto adjacent property.
Flood Zones
Some RestrictionsRialto participates in the National Flood Insurance Program (NFIP, CID 060274) and enforces FEMA floodplain construction standards. Most of the developed city is in Zone X (minimal flood risk), but portions along the Cactus Basin, Lytle Creek wash, and tributaries of the Santa Ana River carry Zone A / Zone AE Special Flood Hazard Area designations under the San Bernardino County FIRM panels effective August 28, 2008. Construction in SFHAs requires elevation to or above base flood elevation (BFE) and a floodplain development permit.
Erosion Control
Heavy RestrictionsRialto requires erosion and sediment control Best Management Practices on all grading and construction sites under the California Building Code Appendix J (adopted in Title 15) and the city's grading ordinance. Projects disturbing 1 acre or more must obtain coverage under the State Construction General Permit (NPDES CAS000002) and implement a SWPPP. Wind-erosion (PM10) controls are also required by SCAQMD Rule 403 (Fugitive Dust) given Rialto's South Coast Air Basin location.
Coastal Development
Few RestrictionsNo local coastal development rule applies in Rialto. The California Coastal Act (Cal. Public Resources Code ยง30000 et seq.) and the Coastal Commission's permit jurisdiction extend only to the legally defined Coastal Zone along the Pacific Ocean. Rialto is located in the Inland Empire (San Bernardino County), approximately 60 miles inland from the nearest point of the Coastal Zone, and is entirely outside Coastal Commission jurisdiction.
๐ชง Sign RegulationsFull sign regulations guide โ
Political Signs
Some RestrictionsRialto regulates temporary signs (including political/campaign signs) under Title 18 Zoning, Chapter 18.78 Sign Regulations. Content-neutral standards apply to size, height, location, and removal. State law (Cal. Gov. Code ยง65850 and First Amendment case law, e.g., Reed v. Town of Gilbert) prohibits content-based discrimination, so political signs are generally treated as temporary signs subject to the same neutral time/place/manner rules.
Holiday Displays
Few RestrictionsRialto has no ordinance specifically restricting residential holiday lighting or seasonal displays. General zoning, nuisance, noise, and electrical code rules apply: displays cannot create a public nuisance, spill excessive light onto neighbors, block sidewalks, or violate Title 24 / NEC electrical standards. Animatronic or audio displays must comply with Ch. 9.50 Noise Control.
Garage Sale Signs
Some RestrictionsGarage sale signs in Rialto are regulated as temporary signs under Title 18, Chapter 18.78 (Sign Regulations) and as part of garage sale rules typically administered through Code Enforcement/Business Licensing. Signs may not be posted in the public right-of-way, on utility poles, or on street trees, and must be removed promptly after the sale.
๐๏ธ Trash & RecyclingFull trash & recycling guide โ
Yard Waste Collection
Some RestrictionsRialto's green organics cart accepts bagged food waste, grass clippings, leaves, branches under 6 inches in diameter, prunings, twigs, weeds, palm fronds, and horse manure. California SB 1383 (effective 2022, residential rollout summer 2023) makes organics diversion mandatory statewide.
Bin Placement Rules
Some RestrictionsCarts must be placed at the curb the morning of collection (or the evening before) and brought back behind the property line after pickup. Rialto Municipal Code Title 8 (Health & Sanitation) prohibits leaving carts in public view between collection days.
Pickup Rules & Schedules
Some RestrictionsRialto contracts with Burrtec Waste Industries (per Title 8 Health & Sanitation franchise) for weekly residential collection of trash, recycling, and green/organic waste. When a holiday falls on a weekday, service is delayed one day for the remainder of that week.
Illegal Dumping

Recreational Drones
Some RestrictionsNo standalone drone ordinance was located in the Rialto Municipal Code (Municode publisher, Titles 1-18). Recreational drone flight in Rialto is governed by FAA Exception for Limited Recreational Operations (49 U.S.C. ยง44809), Part 107 for any non-recreational use, and California's privacy and emergency-response statutes โ Penal Code ยง402b (interference with first responders), Penal Code ยง11414 (harassing a child with intent), and Civil Code ยง1708.8 (aerial constructive invasion of privacy). Rialto sits beneath the San Bernardino International Airport (KSBD) Class D shelf and adjacent Ontario International (KONT) Class C; LAANC authorization through B4UFLY is generally required across most of the city.
Commercial Drones
Some RestrictionsCommercial drone work in Rialto โ real-estate photography, warehouse roof inspections, intermodal-yard surveying, film crews โ is governed by FAA Part 107. The FAA holds sole authority over the navigable airspace; operators need a valid Part 107 Remote Pilot Certificate, current aircraft registration, and Remote ID broadcast (Part 89). Most of Rialto sits within Class D / Class C controlled airspace from San Bernardino International (KSBD) and Ontario International (KONT), so LAANC authorization is required for nearly all flights. Filming on Rialto city property, in city parks, or in public rights-of-way triggers the City's film/special-event permit process administered through the City Clerk.
Park Drone Restrictions
Some RestrictionsRialto Community Services & Recreation operates the city's parks (Frisbie Park, Jerry Eaves Park, Margaret Todd Park, Andreson Park, Bud Bender Park, and others). The Rialto Municipal Code does not contain a standalone 'drones in parks' chapter, but RMC Title 12 (Streets, Sidewalks and Public Places) gives the city authority to restrict activities that interfere with the peaceful use and enjoyment of parks. San Bernardino County Regional Parks (Glen Helen, Cucamonga-Guasti, Prado) prohibit motor-driven equipment off designated roadways and enforce 10 p.m.-7 a.m. quiet hours, which functionally limits drone use. California State Parks land under 14 CCR ยง4351 prohibits motorized equipment (including drones) in wilderness areas, cultural preserves, and natural preserves, with District Superintendent posted orders controlling elsewhere.

Parkway Planting
Some RestrictionsThe parkway strip between curb and sidewalk in Rialto is public right-of-way regulated by Title 12 (Streets, Sidewalks and Public Places). Planting, replacing, or removing a parkway tree requires Public Works approval, and species must come from the city's approved street-tree palette. New subdivisions and large developments must install street trees as a condition of map and site approval under Title 17 (Subdivisions) and Title 18 (Zoning).
Tree Removal Permits
Some RestrictionsRialto has no standalone heritage/native tree ordinance for private single-family parcels. Removal of street trees, parkway trees, and trees on developed sites is regulated through Public Works (Title 12) and the design review/landscaping provisions of Title 18 Zoning. Required landscaping installed under an approved site plan generally cannot be removed without a replacement plan approved by the Planning Division.
Tree Replacement Requirements
Some RestrictionsReplacement of removed trees in Rialto is required in two contexts: (1) removal of a city-owned street or parkway tree under Title 12 (replacement species and size set by Public Works), and (2) removal or loss of trees installed under an approved Title 18 landscape plan, which must be replaced consistent with the original conditions of approval. There is no fixed citywide replanting ratio for private trees outside these contexts.
Heritage & Protected Trees
Few RestrictionsRialto does not maintain a designated heritage or landmark tree ordinance. There is no citywide registry of protected specimen trees, and protections instead flow through public right-of-way rules (Title 12) and conditioned landscaping on approved development sites (Title 18). California does not preempt or require a local heritage tree program.
Protected Tree Species
Some RestrictionsRialto's municipal code does not designate a list of protected native tree species. Native and sensitive species are instead protected through state law (CEQA, California Fish and Game Code รยง1600 series for riparian, and federal/state endangered species rules) and through site-specific biological mitigation conditions during entitlement review under Title 18 Zoning.
