Showing ordinances that apply to Niland, CA
Niland is an unincorporated community with a population of approximately 756 in Imperial County, California. Because Niland is not an incorporated city, it does not have its own municipal government or city code. Instead, Imperial County ordinances apply directly to residential and commercial properties here. The rules below are the county-level regulations that govern your area. Nearby incorporated cities in Imperial County may have different rules.
Unincorporated Imperial County sets nighttime quiet hours of 10 p.m. to 7 a.m. under Title 9, Division 7. During these hours the allowable one-hour average sound level drops, and amplified devices plainly audible at 50 feet become prima facie violations.
Unincorporated Imperial County's Title 9, Division 7 noise ordinance does not set specific construction work-hour windows. Construction equipment is defined and is subject to the County's general sound-level limits and nuisance prohibitions rather than a fixed start/stop time.
Title 9, Division 7, Section 90703.02 makes it unlawful to keep animals whose frequent or long-continued noise annoys a reasonable person nearby. Noise disturbing two or more adjacent households, or three or more nearby households, is prima facie evidence of a violation.
Imperial County's Title 9, Division 7 noise ordinance has no leaf-blower-specific section. Leaf blowers are regulated by the County's general sound-level limits and nuisance rule, plus California's statewide CARB phase-out of new gas-powered small off-road engines (effective 2024).
Title 9, Division 7, Section 90703.02 prohibits operating radios, amplifiers, instruments and similar devices so as to disturb the peace of a reasonable person in any residential or public area. Operation plainly audible at 50 feet between 10 p.m. and 7 a.m. is prima facie evidence of a violation.
Title 9, Division 7, Section 90702.01 makes it unlawful to operate a motor vehicle off public roads so as to exceed the noise limits set for on-highway vehicles under California Vehicle Code Section 23130, with distance corrections. Unnecessary horn use is also prohibited under Section 90703.02.
Title 9, Division 7, Section 90702.00 sets one-hour average sound-level limits by zone, measured at the property line: 50 dB day / 45 night for R-1; 55 / 50 for other residential; 60 / 55 for commercial; and 70 to 75 dB anytime for industrial, agricultural and extraction uses.
Outdoor and amplified music in unincorporated Imperial County is governed by Title 9, Division 7. Playing radios or sound devices in public parks, beaches, lots or adjacent streets over 60 dB at 50 feet (or 60 CNEL) is prohibited without Parks Director approval, and nighttime devices plainly audible at 50 feet are prima facie violations.
Title 9, Division 7, Section 90702.00 caps manufacturing, industrial, agricultural and extraction uses at 70 dB (one-hour average) at any time, and general industrial at 75 dB. Standard agricultural field operations are exempt under the County's Right to Farm approach.
Imperial County's Title 9, Division 7 noise ordinance exempts helicopters at permitted heliports/helistops from its sound-level limits, and aircraft in flight are largely preempted by federal (FAA) law. The County manages aircraft compatibility through airport zoning and land use, not in-flight noise limits.
Unincorporated Imperial County has no dedicated short-term rental or vacation rental ordinance. STRs are governed by the Title 9 Land Use Ordinance instead. Transient lodging is treated as a commercial use (hotel/motel) or guest ranch, neither of which is a permitted use in residential zones, so a discretionary permit is typically required.
There is no short-term rental registration program in unincorporated Imperial County. The only mandatory registration that applies to transient rentals is the Transient Occupancy Tax under Code Chapter 4.16, which requires anyone furnishing lodging to transients to register and collect the County's 8% tax.
Short-term rentals in unincorporated Imperial County are subject to the County's Transient Occupancy Tax. The County confirms the TOT rate is currently 8%, applied to guest stays of 30 days or less, under Chapter 4.16 of the Code of Ordinances. There is no separate STR licensing fee because the County has no STR ordinance.
No short-term-rental-specific parking rule exists in unincorporated Imperial County. Off-street parking is governed by Title 9, Division 4, Chapter 2 (§ 90402.01), which sets ratios by use: two spaces per single-family dwelling, one space per bedroom for boarding/rooming/residential hotels, and one space per room for hotels and motels.
Unincorporated Imperial County sets no short-term-rental-specific occupancy cap, because it has no STR ordinance. Occupancy is governed indirectly by the Title 9 Land Use Ordinance, the adopted California building and residential codes (Division 10), and general health-and-safety limits rather than a per-guest rental rule.
Unincorporated Imperial County has no STR-specific noise standard and no numeric decibel ordinance in its Land Use Code. Noise from rentals is handled through the County's general nuisance provisions and the residential-character expectations of the zoning code, plus standard disturbance-of-the-peace enforcement by the Sheriff.
Unincorporated Imperial County imposes no primary-residence requirement on short-term rentals, because it has not adopted an STR ordinance. Nothing in the Title 9 Land Use Ordinance ties transient rental to owner residency; the controls are zoning use classification and the 8% Transient Occupancy Tax instead.
Unincorporated Imperial County has no host-presence or on-site-operator requirement for short-term rentals, since it has no STR ordinance. The Title 9 Land Use Ordinance does not mandate that an owner or local contact be present, though a Conditional Use Permit for a lodging use could impose operating conditions.
Unincorporated Imperial County sets no annual night cap or limit on rental days for short-term rentals, because it has no STR ordinance. The only day-count threshold that matters is the Transient Occupancy Tax definition of a transient — generally a stay of 30 days or less, which triggers the County's 8% TOT.
Unincorporated Imperial County imposes no short-term-rental liability-insurance requirement, because it has no STR ordinance. No minimum coverage amount is set in the Title 9 Land Use Ordinance. Insurance is left to the property owner and any conditions a Conditional Use Permit might attach to a commercial lodging use.
In unincorporated Imperial County all fireworks are banned, including state-approved "safe and sane" fireworks. Chapter 8.24 of the County Code of Ordinances prohibits possession, sale and use, and the Imperial County Fire Department enforces it. "Safe and sane" fireworks are legal only inside the seven incorporated cities.
All outdoor burning in Imperial County must have prior authorization from the Air Pollution Control District (ICAPCD). Residential green-waste burning is allowed only outside cities and townships, only on declared Burn Days, and only for vegetation grown on that property. Agricultural burning is permitted under ICAPCD Rule 701.
Imperial County is desert and irrigated farmland with very little wildland brush, so there is no county-wide 100-foot defensible-space mandate. The Imperial County Fire Department abates overgrown weeds and rubbish as a fire hazard and public nuisance through a notice-and-abatement process, and state defensible space (PRC 4291) applies only on the limited State Responsibility Area land.
Backyard fires in unincorporated Imperial County split into two categories: clean wood/charcoal recreational fires follow the California Fire Code, while burning yard waste or trash is open burning that requires prior ICAPCD authorization. There is no separate county backyard-fire ordinance; recreational fires must stay 25 feet from structures and be attended.
Imperial County follows California state smoke-alarm and carbon-monoxide requirements rather than a unique county ordinance. State law requires smoke alarms in every bedroom, outside each sleeping area, and on every story, plus carbon-monoxide alarms in dwellings with fuel-burning appliances or attached garages.
Propane (LPG) storage in unincorporated Imperial County is governed by the California Fire Code and NFPA 58 enforced by the Imperial County Fire Department, not by a separate county propane ordinance. Tank installations are permitted and inspected, and on the limited fire-hazard land state law calls for 10 feet of clearance around LPG tanks.
Imperial County has among the lowest wildfire hazard in California. CAL FIRE's 2022 mapping shows only about 1,780 acres of Moderate Fire Hazard Severity Zone in the State Responsibility Area and zero acres of High or Very High zones. Most of the county is irrigated farmland and desert in the Local Responsibility Area.
Imperial County has no fireworks-style ordinance specific to backyard fire pits, so recreational fires follow the California Fire Code (Section 307) and ICAPCD air rules. Recreational fires must stay 25 feet from structures, be constantly attended, and any open burning of waste needs prior authorization from the Air Pollution Control District.
On unincorporated county roads, Imperial County Code Section 10.24.010 sets the basic street-parking rules: park parallel and within 18 inches of the right-hand curb or road boundary, and do not leave a vehicle standing for 72 or more consecutive hours. State Vehicle Code rules on prohibited locations also apply.
Imperial County does not impose a blanket overnight parking ban on county roads. The operative limit is the 72-hour rule in County Code Section 10.24.010, so overnight parking is generally allowed as long as the vehicle is moved before three days pass and is parked within 18 inches of the curb.
Imperial County Code Section 10.24.010 gives commercial vehicles a narrow break from the 72-hour parking limit while they are actively loading or unloading passengers or merchandise. Otherwise commercial vehicles must obey the same county and California Vehicle Code parking rules as any other vehicle.
Imperial County treats abandoned, wrecked, dismantled or inoperative vehicles on private and public land as a public nuisance under the Title 9 Land Use Ordinance (Division 27). On county roads, a vehicle left 72 or more consecutive hours may be removed under County Code Section 10.24.010 and the California Vehicle Code abandonment rules.
Imperial County does not have a stand-alone driveway-parking chapter; blocking driveways is governed by California Vehicle Code Section 22500, which prohibits stopping in front of any public or private driveway. New or modified driveways onto county roads require an encroachment permit from the Department of Public Works.
Imperial County's parking chapter does not set a separate size cap for oversized vehicles on county roads; the 72-hour and 18-inch curb rules of Section 10.24.010 apply. California Vehicle Code Section 22507 lets the county restrict tall vehicles (six feet or more, including load) near intersections by ordinance with posted signs.
Imperial County has no separate EV-charging-space ordinance. Parking in a marked electric-vehicle charging space in the unincorporated area is governed by California Vehicle Code Section 22511, which lets posted spaces be reserved for vehicles actively connected for charging and allows towing of vehicles that are not.
Imperial County's parking code exempts vehicles actively loading or unloading passengers or merchandise from the 72-hour limit. Painted loading zones follow California Vehicle Code Section 21458 - yellow curbs for freight/passenger loading and white curbs for passenger loading - and apply during the hours set by local ordinance.
Imperial County follows the statewide curb-color system in California Vehicle Code Section 21458 - red, yellow, white, green and blue. Only the county or its authorized agents may mark curbs to create enforceable restrictions; unauthorized curb painting in the county right-of-way is not permitted.
Imperial County has no chapter that singles out RVs, trailers or boats by name on county roads. On-street RV parking in the unincorporated area is governed by the general parking rules of Title 10, Chapter 10.24 and the California Vehicle Code, with the 72-hour limit being the practical cap.
In unincorporated Imperial County, Title 9, Division 4, Chapter 3 limits fencing in a required front yard of an 'R' or residential 'A' zone to 30 inches if obscure or 48 inches if translucent. Wood, stucco, wrought iron and chain link fences under 6 feet are approved in any zone.
Unincorporated Imperial County does not require a building permit for masonry walls four feet or less in height, but those still must meet the County's masonry-fence handout and pass foundation, reinforcement and final inspections. Masonry fences over four feet must be engineered and built to the adopted California Building Code.
Imperial County's Title 9 fence rules add a corner-lot sight-distance limit (fencing may not exceed 30 inches where it would obstruct traffic visibility). Cost-sharing for a shared boundary fence is governed by California's statewide Good Neighbor Fence Law, Civil Code Section 841, which presumes adjoining owners share costs equally.
Imperial County's Title 9 fence chapter focuses on masonry walls rather than soil-retaining walls. Masonry walls over four feet must be engineered and built to the adopted California Building Code; masonry four feet or less needs no building permit but requires foundation, reinforcement and final inspections. Retaining-wall permitting follows the adopted Building Code.
Title 9, Division 4, Chapter 3 requires fences in unincorporated Imperial County to be built of approved fencing or construction materials, kept within height and sight-distance limits, and engineered if masonry over four feet. Junk materials like tires, cans, broken glass and used car parts are not allowed.
Title 9, Division 4, Chapter 3 bars barbed or razor-edge wire in all residential zones and on property abutting residential areas, and prohibits electrified fences in all zones except for animal containment in 'A' (agricultural) zones or security fencing at government institutions. Junk materials are also banned.
Title 9, Division 4, Chapter 3 approves wood, stucco, wrought iron and chain link fencing under 6 feet in any zone in unincorporated Imperial County. Masonry over four feet must be engineered to the adopted California Building Code. Barbed/razor wire and electric fencing are restricted, and junk materials are banned.
Imperial County's animal regulations and California state law focus on a dog's individual behavior, not its breed. We found no breed-specific ban (such as a pit bull ban) in the county's rules. Dangerous-dog determinations are made case by case under state law based on what the dog actually does.
Beekeeping in unincorporated Imperial County is shaped by the zoning code (where hives may go) and by California state law, which requires every beekeeper to register their apiary annually with the County Agricultural Commissioner. Registration is required regardless of the number of colonies or whether you keep bees as a hobby or business.
Exotic and wild animals are tightly restricted by California state law, which applies throughout unincorporated Imperial County. Many species cannot be kept as personal pets at all. The state restricted-species rules, not just county code, are what most residents run into when trying to keep an unusual animal.
Imperial County is a major agricultural county where cattle, dairy and feedlot operations are well established. Livestock keeping is governed by the zoning code (Title 9). Residential zones allow limited livestock by lot size, while the agricultural zones - especially A-3 (Heavy Agriculture) - accommodate large feedlots and dairies.
In the R-1 residential zone of unincorporated Imperial County, the zoning code limits small domestic pets such as cats and dogs to five of any one or combination. Keeping more dogs may also bring a parcel into kennel territory, and excessive numbers can implicate state animal-cruelty law.
Cats in unincorporated Imperial County are treated mainly through the zoning code's household-pet limit (five cats and dogs combined in R-1) and through Animal Care and Control's adoption, spay/neuter and vaccination services. We did not find a mandatory cat-licensing requirement comparable to the county's dog rules.
We did not locate a specific Imperial County ordinance prohibiting the feeding of wildlife in unincorporated areas. Wildlife is instead protected and managed primarily under California state law, and attracting wildlife can create nuisance and public-health problems that Animal Control and Environmental Health may address.
Animal hoarding in unincorporated Imperial County is addressed mainly through California's animal-cruelty law. Keeping animals in numbers that compromise their health and safety through overcrowding can be prosecuted under Penal Code section 597, and Imperial County Animal Care and Control investigates cruelty cases across the unincorporated areas.
In unincorporated Imperial County, dogs are regulated under County Code Title 6 (Animals), enforced by the Public Health Department's Animal Care and Control Program. Dogs are expected to be under control and not running at large; loose-dog and bite complaints across the county's 4,000-plus square miles of towns, desert and farmland are handled by Animal Control.
Keeping chickens and small livestock in unincorporated Imperial County is governed by the zoning code (Title 9). In the R-1 residential zone, residents may keep up to five small fowl, rabbits or birds (in any one or combination) for domestic or hobby use in proper enclosures, with larger animals allowed only on bigger parcels.
Unincorporated Imperial County has no fixed numeric grass-height limit. Title 9 Division 18 makes it unlawful for any owner or occupant to let land become overgrown and infested with weeds and other vegetation, using a 'fire menace when dry' and 'noxious or dangerous' standard rather than an inch measurement (Title 9 §§91801.00-91801.01).
Imperial County has no general ordinance requiring permits to trim or prune trees on private property in unincorporated areas. Trees that overgrow into a fire menace or otherwise become noxious or dangerous can be abated under the Title 9 Division 18 weed-and-vegetation provisions, and obstructions in street rights-of-way must be cleared.
Unincorporated Imperial County does not have a heritage-tree or general tree-removal permit ordinance for private property. Homeowners may generally remove trees on their own land. Trees planted to satisfy a development's required landscaping must be kept alive and maintained under Title 9 Division 3.
Title 9 Division 18 makes it a misdemeanor to let land in unincorporated Imperial County become overgrown and infested with weeds and other vegetation. Weeds include brush that becomes a fire menace when dry plus noxious or dangerous growth. The county can declare a public nuisance, abate it, and lien the property for costs.
Imperial County's Title 9 Land Use Ordinance contains no ordinance prohibiting or specifically permitting residential rainwater harvesting. California law broadly allows rooftop rainwater capture for landscape use. In this low-rainfall desert, most landscape irrigation comes from Imperial Irrigation District Colorado River water rather than captured rain.
Imperial County's landscape ordinance (Title 9 Division 3) requires plants suited to the region, grouped by water need and irrigated separately, with a 30-inch/year supplemental-water cap and 3 inches of organic mulch in shrub areas. It references drought-tolerant plant guides such as 'Trees and Shrubs for Dry California Landscapes,' encouraging low-water and desert-adapted species.
Imperial County's landscape ordinance (Title 9 Division 3) repeatedly states that ornamental rock, gravel, artificial turf, or other artificial-cover areas do NOT count toward a development's minimum required landscaped percentage. Artificial turf is allowed, but covered projects must still provide live, irrigated landscaping to meet their landscaped-area minimums.
California's SB 1383 requires organic-waste diversion countywide. In the Imperial Valley the program is run by the Imperial Valley Resource Management Agency (IVRMA), whose members include the County of Imperial. Residents must use organics (green-cart) collection or, where allowed, self-haul or compost on site; backyard composting is one accepted way to divert organics.
Title 9 Division 3, Chapter 2 is Imperial County's water-conserving landscape ordinance. New non-residential, multi-family, and subdivision landscaping must limit supplemental irrigation to an average of no more than 30 inches of water per year, use low-volume/drip irrigation and automatic rain-shutoff controllers, and group plants by water need. The state MWELO also applies.
In unincorporated Imperial County, a private residential pool, spa or hot tub over two feet deep is a regulated structure under Title 9 and the adopted California Residential Code. Plans go through Planning & Development Services (Building Division); only public pools also require an Environmental Health permit.
Imperial County Title 9, Division 10 requires every swimming pool in the unincorporated area to be enclosed by a wall, fence or other structure at least five (5) feet high, with self-closing, self-latching gates whose latches sit at least five feet above ground and that are kept closed and latched at all times.
Beyond the five-foot enclosure, Imperial County requires pools to meet the County-adopted California Residential Code Appendix V (Swimming Pool Safety Act) and California Electrical Code equipotential bonding rules. The state Pool Safety Act requires at least two of seven drowning-prevention features at permit time.
Imperial County Title 9 makes no separate exemption for above-ground pools. Any above-ground pool, on-ground pool or fixed wading pool over two feet deep is a regulated swimming pool subject to the same setbacks, five-foot enclosure, and adopted-code safety rules as in-ground pools.
Imperial County treats hot tubs and spas as swimming pools. Under Title 9, Division 10, any hot tub or spa over two feet deep is a regulated pool that must meet the five-foot enclosure, self-latching gate, adopted-code safety, and zoning setback rules — though a code-compliant safety cover is an accepted alternative.
In unincorporated Imperial County a home business is a 'home occupation' under Title 9, Division 4, Chapter 4 — a residential accessory use so conducted that the average neighbor would be unaware of it. It must be run by the resident, use no more than 20% of the home, and create no nuisance.
Home occupations in unincorporated Imperial County may not advertise on site at all. Title 9, Division 4, Section 90404.03(K) states there shall be no sign permitted on the site indicating the service provided — keeping the business invisible to neighbors.
A home occupation in unincorporated Imperial County requires a Home Occupation Permit from the Planning Director before it operates. Under Title 9, Division 4, neighbors within 500 feet get a 10-day mailed notice, and an opposed application goes to an administrative hearing.
Imperial County expressly lists a cottage food operation as a permitted home occupation under Title 9, Division 4, Section 90404.01(D), referencing the California Health & Safety Code. State law (HSC 113758 and Gov. Code 51035) bars counties from banning cottage food in homes, so it is allowed subject to the County's home-occupation standards.
Imperial County's home-occupation ordinance lists 'Day care, school or pre-school' as a prohibited home occupation, but California state law overrides this for licensed family daycare homes: HSC 1597.45 makes small and large family daycare a residential use by right that local zoning cannot prohibit.
Unincorporated Imperial County regulates ADUs and JADUs in Title 9, Division 4, Chapter 5 (Section 90405). In a June 26, 2025 review letter, California HCD found parts of the county ordinance noncompliant with State ADU Law (Gov. Code 66310-66342), so state standards control where the local code is more restrictive.
Detached sheds and accessory buildings in unincorporated Imperial County are regulated as accessory buildings under Title 9, Division 5, Section 90501.12. In residential (R) zones they cannot exceed three stories or 35 feet, cannot sit in the front yard of the primary use, and if over one story must stay at least 5 feet from any interior property line.
Converting an existing garage to an ADU is expressly allowed in unincorporated Imperial County. Title 9, Section 90405.03.G requires no setback for an existing garage converted to an ADU. State ADU Law (Gov. Code 66314) further bars the county from requiring replacement parking when a garage is converted.
Carports and private garages in unincorporated Imperial County are regulated as accessory buildings under Title 9, Division 5, Section 90501.12. An attached private garage may reach 1,000 square feet; outside Urban Areas on A-2, A-3, S-1 and S-2 parcels larger detached garages follow an acreage table, and those 4,000 sq ft or over need an administrative permit.
Unincorporated Imperial County has no standalone 'tiny home' ordinance. A small fixed-foundation dwelling is treated as an ADU under Title 9, Section 90405 (detached units up to 1,200 sq ft) or a JADU up to 500 sq ft. Living in a tiny home on wheels or RV outside a licensed park is barred by the county Camping Ordinance (Section 92903.02).
Backyard barbecuing with propane or charcoal is allowed in unincorporated Imperial County and is not separately licensed. The main rule comes from the California Fire Code: at multi-family and similar properties, barbecue grills and propane appliances must be kept at least 15 feet from structures. Single-family homes have more flexibility but should follow clearance and safety basics.
Using a backyard smoker (wood, pellet, charcoal or propane) for cooking is allowed in unincorporated Imperial County and needs no air-district burn authorization, because cooking is not waste burning. The California Fire Code's cooking-fire clearance and attendance rules apply, and persistent smoke that disturbs neighbors could be addressed as a nuisance.
Setbacks in unincorporated Imperial County are set per zone in Title 9, Division 5. In the R-1 (Low Density Residential) zone, Section 90502.06 requires a 25-foot front yard (20 feet if the lot is less than 90 feet deep), 5-foot side yards (15 feet on a corner street side), and a 10-foot rear yard with a qualifying alley.
Maximum building height in unincorporated Imperial County is set per zone in Title 9, Division 5, not by a single countywide number. Masonry fences and walls over four feet must be engineered to the adopted California Building Code. Confirm the height limit for your specific zone with Planning & Development Services.
Lot coverage and minimum lot size in unincorporated Imperial County are set per zone in Title 9, Division 5. In the R-1 zone, Section 90502 requires a minimum 6,000 square feet net per lot and one dwelling unit per legal parcel, with buildable area shaped by the zone's 25-foot front, 5-foot side and 10-foot rear setbacks.
Unincorporated Imperial County treats accumulated trash, junk, and other deteriorating conditions as a public nuisance under Title 9. Section 90501.20 makes it a misdemeanor or infraction to let trash, rubbish, garbage, cans, bottles, paper, or refuse accumulate on private property where it can support vermin, and Division 13 provides the abatement and cost-lien process.
Historically the unincorporated county had no franchised carts, so trash-can storage was governed only by the Title 9 nuisance and waste-accumulation rules. Starting July 1, 2026, mandatory three-cart collection brings standardized 96-gallon black (trash), blue (recycling), and green (organics) containers to franchised unincorporated zones, with placement set by the hauler.
Owners of vacant parcels in unincorporated Imperial County must keep them free of overgrown weeds, accumulated trash, junk, and abandoned vehicles. These conditions are nuisances under Title 9: Division 18 covers weeds, §90501.20 covers waste accumulation, and Division 26 covers inoperative vehicles, all abatable with a cost lien.
Title 9, Division 18 makes it unlawful for any owner or occupant in unincorporated Imperial County to let land become overgrown and infested with weeds and other vegetation. The county uses a 'fire menace when dry' and 'noxious or dangerous' standard rather than an inch measurement, with a misdemeanor penalty and a cost-lien abatement process.
Garage and yard sales are allowed in unincorporated Imperial County residential zones without a special use permit, but Title 9 limits each sale to two consecutive days and no more than two sales per year, contained on the property. Directional signs not removed within 24 hours after the sale are fined $50, and violations are a misdemeanor.
Unincorporated Imperial County historically had no curbside collection; residents self-hauled waste to county disposal sites. Effective July 1, 2026, the county's Solid Waste Franchise Zone program makes weekly three-cart collection mandatory in franchised unincorporated areas at about $26.51 per month, billed annually on the property tax roll, with no residential waivers.
Because unincorporated Imperial County had no curbside service until 2026, there is no detailed numeric set-out ordinance. Under the new franchise program, set-out time and cart placement are governed by the assigned hauler (CR&R or Republic Services). Containers left to accumulate refuse can still be abated as a Title 9 nuisance.
Unincorporated Imperial County residents have traditionally self-hauled bulky items and household trash to county disposal sites, several of which offer limited free drop-off with valid ID and a matching water bill. The county operates nine landfills/disposal sites, and the new franchise program adds collection service; illegal dumping of bulky items is separately prohibited.
Recycling in unincorporated Imperial County is driven primarily by California state law - AB 341 mandatory commercial recycling and SB 1383 - rather than a detailed county recycling code. The new franchise program adds a blue recycling cart to every covered home effective July 1, 2026, alongside the trash and organics carts.
California's SB 1383 requires organic-waste (food scraps and yard waste) collection statewide. With ~180,000 residents, Imperial County exceeds the 70,000 rural-county threshold, so there is no blanket waiver - though low-density desert census tracts may qualify for CalRecycle waivers. The county's mandatory green-cart program takes effect July 1, 2026, with no residential waivers.
Unincorporated Imperial County allows temporary political, religious, or civic campaign signs for up to 120 days under Title 9, Section 90401.09. Signs must be removed within 15 days after Election Day, and in residential areas may not exceed 20 square feet or 6 feet in height. Signs remaining 20 days after the campaign incur a $50-per-day fine.
Unincorporated Imperial County's sign code (Title 9, Division 4, Chapter 1) has no provision specifically naming garage-sale or yard-sale signs. Such temporary off-premise signs are not among the listed permitted or exempt signs, and any sign not authorized by the chapter is prohibited under Section 90401.14.G, with deviations requiring a Conditional Use Permit.
Unincorporated Imperial County has no comprehensive dark-sky or outdoor-lighting ordinance. The only county lighting controls in Title 9, Division 4 are anti-glare requirements for signs and a rule (Section 90402.13.L) that lights used to illuminate parking areas must be directed away from adjacent properties and streets.
Unincorporated Imperial County has no general light-trespass ordinance. The county's only spill-light controls are in Title 9, Division 4: parking-area lights must be directed away from adjacent properties and streets (Section 90402.13.L), and sign lighting must not produce glare on adjacent properties. Other light-trespass disputes fall to California nuisance law.
These unincorporated areas are also governed by Imperial County ordinances.
