Rohnert Park, CA

Rohnert Park does not require a building permit for residential fences, but fences must comply with Chapter 17.14 (Fence, Wall, and Landscape Standards) of the Zoning Code. Fences, walls, hedges, and vegetation cannot exceed 3 feet within the clear vision triangle at corners and driveways per § 17.14.040, and standard residential height limits apply outside that triangle. The Planning Department at 130 Avram Avenue handles questions.

Rohnert Park zoning permits standard residential fence materials (wood, vinyl, masonry, ornamental metal, chain link). Barbed wire, razor wire and electric fencing are generally restricted in residential zones.

Shared boundary fences in California are governed by the Good Neighbor Fence Act (CA Civil Code §841), presuming adjoining owners share the cost of a boundary fence equally after 30 days' notice. Spite fences over 10 feet are a private nuisance (§841.4).

Rohnert Park zoning typically allows fences up to 6 feet in side and rear yards and 3–4 feet in front yards, with corner-lot sight-visibility limits. Taller fences require a permit or variance.

Fences in unincorporated Sonoma County must meet zoning height limits by yard, sit at least 6 inches outside public rights-of-way and easements, and be measured from the lowest existing grade. No fencing is allowed in a designated floodway (F1), and riparian-corridor fences are limited to about 4 feet of wildlife-friendly open fencing.

A fence built on top of a retaining wall in unincorporated Sonoma County cannot exceed the allowable fence height when the wall and fence are combined. Fence height is measured from the lowest existing grade to the topmost point, so a wall counts toward the limit. Structural retaining walls require a separate building permit.

Under the 2025 objective standards, residential and K-district fences in unincorporated Sonoma County must use allowed materials such as wood, naturalistic composite wood, stone/masonry, stucco, and non-reflective woven metal or wire. Glass, exposed bunker blocks, razor wire, reflective metal, and barbed wire are prohibited (except qualifying agricultural fences).

California's Swimming Pool Safety Act in Health and Safety Code Section 115920 mandates statewide drowning prevention barriers around residential pools, with cities prohibited from adopting weaker standards.

Rohnert Park's Zoning Code Title 17 (Chapters 17.06 and 17.10) regulates accessory structures including sheds. One-story detached accessory structures (tool/storage sheds, playhouses) up to 120 sq ft are exempt from a building permit per the California Building Code, but must still comply with the underlying residential zoning district's setback and height standards. The Development Services Department reviews larger sheds and any structure with electrical or plumbing.

California's statewide ADU law (Gov. Code §65852.2) requires Rohnert Park to allow accessory dwelling units on residential lots by right — detached ADUs up to 1,200 sq ft, 4-foot side/rear setbacks, no owner-occupancy requirement, and no added parking within ½ mile of transit.

Converting a garage to living space in Rohnert Park requires a building permit and zoning review for egress, light/ventilation and parking; converting a garage to a separate unit is often processed as an ADU under state law.

A permanently sited tiny home on a foundation is typically permitted in unincorporated Sonoma County as an ADU under County Code Sec. 26-88-060 (max generally 1,200 sq ft), processed ministerially. Movable tiny homes on wheels and RVs are not treated as permanent dwellings and face separate restrictions.

Carports are treated as detached residential accessory structures in unincorporated Sonoma County. A building permit is required at 120 square feet or larger under Permit Sonoma's policy, and carports must meet the setback, height, and lot-coverage standards of the parcel's zoning district under Chapter 26.

Rohnert Park regulates noise through its municipal nuisance/noise provisions, prohibiting loud and disturbing noise. Nighttime disturbances (generally after 10 p.m.) are the primary enforcement focus; California sets no statewide residential dB limit.

Construction noise in Rohnert Park is limited to daytime hours under the noise ordinance — typically 7 a.m.–7 p.m. on weekdays with more limited weekend hours; work outside the permitted window is a violation. Confirm exact hours with the city.

Persistent dog barking in Rohnert Park is enforced under the noise/nuisance ordinance and animal provisions; chronic barking that disturbs neighbors can be cited.

Sonoma County has no ordinance specifically restricting or banning leaf blowers in the unincorporated area. Leaf-blower noise is treated like other property-maintenance noise, addressed only if it becomes a loud, unreasonable disturbance under state law or General Plan performance standards.

Vehicle noise in unincorporated Sonoma County is governed by California state law, not a County ordinance. Vehicle Code 27150 requires an adequate muffler at all times, and 27151 bans modified exhaust that amplifies noise. The Sheriff and CHP enforce these rules; the County encourages active state enforcement.

Sonoma County has no enforceable countywide decibel ordinance for everyday noise. The General Plan Noise Element Table NE-2 sets exterior performance standards for stationary sources — daytime L50 of 50 dBA and nighttime L50 of 45 dBA at a neighbor's property line — applied mainly through project and permit review.

Outdoor music, concerts and special events in unincorporated Sonoma County are regulated through the use-permit and special-event review process rather than a fixed noise ordinance. The General Plan Noise Element flags amplified outdoor sound as a key concern and applies stationary-source standards, reduced 5 dBA for music.

Industrial and commercial (stationary-source) noise in unincorporated Sonoma County is governed by the General Plan Noise Element's Table NE-2 performance standards, applied through zoning and use-permit review. New sources must not exceed daytime L50 of 50 dBA or nighttime L50 of 45 dBA at an adjacent noise-sensitive property line.

Unincorporated Sonoma County has no dedicated amplified-music ordinance, but the General Plan Noise Element treats amplified sound as especially intrusive: stationary-source standards are reduced by 5 dBA for noise consisting primarily of speech or music. Loud amplified music can also be cited under state disturbing-the-peace law.

This is the one true Sonoma County noise ordinance: Code Chapter 3, Article III limits aircraft noise at the County-owned Sonoma County Airport. Section 3-41 caps takeoff noise at 83.2 dBA (Lmax) during the day and 72 dBA (Lmax) at night, enforced by the Director of Aviation with fines and operating bans.

STR guests in Rohnert Park are bound by the noise/nuisance ordinance — loud or disturbing noise, especially at night, can be cited.

Short-term rentals in Rohnert Park are subject to the city's Transient Occupancy Tax on stays under 30 days, consistent with California cities (commonly 10–14%). Operators must register and remit TOT.

California has no statewide STR licensing framework, so Rohnert Park regulates short-term rentals through its zoning and business-license requirements. Confirm whether STRs are permitted in your zone before listing.

STR guest parking must comply with Rohnert Park zoning off-street parking standards; on-street parking is limited and subject to the city vehicle code.

Sec. 26-88-120(e) caps overnight occupancy at two persons per sleeping room plus two more per property, to a maximum of 12 (children under three excluded). Total daytime guests and visitors may not exceed overnight occupancy plus six, or 18, whichever is less. Rentals may have no more than five guestrooms.

Sonoma County does NOT require vacation rentals to be a primary residence. Sec. 26-88-120 applies precisely to whole-house rentals where there is no primary owner in residence. Owner-occupied 'hosted rentals' are instead governed by Sec. 26-88-118, and a primary owner in residence is exempt from the vacation rental rules.

Sec. 26-88-120 does not set an annual cap on the number of nights a permitted vacation rental may operate; a vacation rental is simply any rental of 30 days or less. Instead, the County controls supply through density 'cap zones' (5% or 10% of single-family homes) and X Exclusion Combining Districts.

Whole-house vacation rentals do not require an on-site host, but Sec. 26-88-120(f)(8) requires a certified 24-hour property manager available 24/7 during rentals and located within 30 miles. By contrast, owner-occupied 'hosted rentals' under Sec. 26-88-118 require the primary owner to reside on the property.

Sec. 26-88-120 does not impose a specific liability-insurance minimum for vacation rentals. Permit Sonoma's application instead requires a signed Indemnification Agreement (Form PJR-011). Operators are responsible for their own coverage, and platforms or lenders may require liability insurance separately.

Beyond the zoning permit, operators must obtain a separate vacation rental license under County Code Chapter 4, Article VIII, register for a Transient Occupancy Tax certificate, and maintain a certified property manager. Permits are posted on-site and neighbors within 300 feet receive mailed notice of issuance.

Repeat vacation rental violations in unincorporated Sonoma County trigger an escalating enforcement ladder, from a warning letter to suspensions of one to six months and license revocation for up to five years for chronic non-compliance.

All fireworks — including California 'Safe and Sane' fireworks — are illegal in Rohnert Park, effective September 2021. Possession or use carries a $1,000 fine, enforced by police and fire. Only professional permitted displays are allowed.

Open burning in Rohnert Park is regulated by the Bay Area Air Quality Management District and the fire authority; residential yard-waste burning is generally prohibited, and burning is barred on Spare the Air days. Wildfire risk drives strict enforcement.

Recreational fires in approved fire pits using clean, dry wood are generally allowed in Rohnert Park subject to fire-code clearances and air-district restrictions; fires must be attended and barred on Spare the Air / red-flag days.

Sonoma County Code Chapter 13A requires owners of parcels in the unincorporated area to maintain defensible space and abate hazardous vegetation year-round. Improved parcels in the Local Responsibility Area must keep 30 feet of defensible space (up to 100 feet if conditions require), limb trees, and clear roadside vegetation. Non-compliance can be abated by the County with costs liened to the property.

Smoke and carbon monoxide alarm requirements in unincorporated Sonoma County follow the California Residential Code as adopted through the County's building and fire codes, plus statewide point-of-sale law. Residential permits over $1,000 in valuation trigger alarm upgrades throughout the dwelling, and at least one CO device must be installed when residential property is sold.

Much of unincorporated Sonoma County lies within Fire Hazard Severity Zones, including State Responsibility Area and Very High zones, reflecting catastrophic fires like Tubbs (2017), Kincade (2019), and Glass (2020). New construction in WUI/SRA and Very High zones must meet ignition-resistant standards under California Building Code Chapter 7A, and SRA/Very High projects require a fire protection plan reviewed before permit issuance.

Backyard burning of vegetation in unincorporated Sonoma County is allowed only with a valid Permit Sonoma burn permit on a permissive burn day, with piles capped at 4 feet, a 10-foot bare-soil clearance, an adult in attendance, and no burning on windy days. Only dry natural vegetation may be burned - trash and debris are prohibited - and burning is suspended during high fire danger.

Propane (LP-gas) and petroleum storage in unincorporated Sonoma County is regulated through the California Fire Code adopted in County Code Chapter 13 and Permit Sonoma's hazardous-materials program. LP-gas installations require a Fire Code permit before filling, and aboveground petroleum facilities of 1,320 gallons or more must maintain a federal SPCC plan under the Aboveground Petroleum Storage Act.

On-street parking in Rohnert Park is governed by the city vehicle code; a vehicle left on a street more than 72 hours is deemed abandoned under CA Vehicle Code §22651 and may be cited or towed.

RV, trailer and boat storage on residential lots in Rohnert Park is regulated by zoning, which restricts placement (typically a paved area) and prohibits living in a parked RV.

Driveway approaches in Rohnert Park require an encroachment permit and must meet city standards; vehicles generally must be parked on an approved paved surface, not on the lawn.

Parking or storing large commercial vehicles in Rohnert Park residential zones is restricted by zoning, with weight/length thresholds limiting what may be kept overnight at a home.

Sonoma County Code Sec. 18-3.10 prohibits parking any 'oversized vehicle' on a County road or right-of-way for more than six consecutive hours, after which it must relocate for at least 72 hours. Oversized means any motor vehicle, boat, or trailer at least 24 feet long, 90 inches high, or 96 inches wide, plus buses, trailers, trailer coaches, and recreational vehicles.

On County roads in unincorporated Sonoma County, loading and passenger-loading zones are established under Sonoma County Code Sec. 18-3.3 and marked by curb paint or signs. Stopping is for loading or unloading only and, unless otherwise posted, may not exceed 20 minutes. Yellow and white curbs carry the meanings set by California Vehicle Code Sec. 21458.

Sonoma County Code Chapter 18, Article IV declares abandoned, wrecked, dismantled, or inoperative vehicles on private or public property in the unincorporated area a public nuisance subject to abatement, under authority of California Vehicle Code Sec. 22660. Permit Sonoma Code Enforcement administers a free junk-vehicle removal program. Vehicles on public roads are handled by CHP and the Sheriff.

Unincorporated Sonoma County has no blanket overnight parking ban on all County roads. Instead, Sonoma County Code Sec. 18-3.3 allows parking to be prohibited between 2:00 a.m. and 6:00 a.m. on designated road portions, and Sec. 18-3.5 lets the Board of Supervisors create posted 'No Overnight Parking' zones by resolution.

Unincorporated Sonoma County has no dedicated County ordinance governing parking in EV charging spaces. The controlling rules come from California Vehicle Code Sec. 22511, which lets local authorities designate charging-only spaces and makes it unlawful to occupy a posted EV charging space unless the vehicle is connected for charging.

On County roads in unincorporated Sonoma County, curb colors follow the statewide system in California Vehicle Code Sec. 21458 - red, yellow, white, green, and blue. Only the Public Works Director / Sonoma Public Infrastructure may apply official curb markings under County Code Sec. 18-3.2, and private address-number curb painting in the unincorporated area requires an encroachment permit.

Rohnert Park requires dogs to be leashed or confined and prohibits dogs running at large; dogs off the owner's property must be leashed. Animal services enforces and may impound loose dogs. California requires dog licensing.

California restricts exotic pets through the Fish & Game Code and CDFW regulations — ferrets and hedgehogs are illegal statewide, and many wild/exotic species are prohibited. These restrictions apply in Rohnert Park.

California prohibits breed-specific bans, so Rohnert Park cannot ban a breed outright; state law allows only breed-specific spay/neuter requirements. The city regulates dangerous/vicious dogs by behavior.

Beekeeping is permitted in Rohnert Park subject to local zoning standards on hive number, placement and setbacks. California has no statewide ban; hives must be registered with the Sonoma County agricultural commissioner.

Livestock in unincorporated Sonoma County is governed by the Zoning Code's animal-density standards administered by Permit Sonoma, with allowances based on zoning district and parcel size. County Code Chapter 5 also protects livestock by addressing dogs that enter property where sheep or other livestock are kept.

In unincorporated Sonoma County, no permit is required to keep up to four dogs and/or four cats on a property. Keeping five or more typically requires a license or use permit. Five to ten animals kept non-commercially can be licensed as a pet fancier facility; five or more kept commercially is a kennel.

Under Sonoma County's Animal Regulation Ordinance (County Code Chapter 5, Article VI), cats four months of age or older must be vaccinated against rabies. Cat registration with Animal Services is voluntary, with reduced fees available for spayed/neutered cats and for owners age 62 or older.

Unincorporated Sonoma County does not have a stand-alone ordinance banning the feeding of wildlife generally, but California regulations control. Title 14 Section 251.3 of the California Code of Regulations prohibits knowingly feeding big game mammals such as deer, and feeding that habituates wildlife can be treated as harassment under the Fish and Game Code.

Unincorporated Sonoma County does not set a specific numeric hoarding threshold; California Penal Code Section 597 governs animal cruelty and neglect. Keeping so many animals that overcrowding compromises their health and safety can be charged as cruelty. County Code Chapter 5 nuisance and sanitation provisions and pet-limit rules also apply.

Keeping chickens and small livestock in unincorporated Sonoma County is governed by the Zoning Code's animal-density rules, administered by Permit Sonoma. Density depends on the zoning district and parcel size. In Rural Residential zoning, one horse or cow, five goats, or fifty chickens are allowed per 20,000 square feet of parcel area.

Outdoor watering in Rohnert Park is subject to city/regional water-conservation rules, including assigned watering days/times and prohibitions on runoff during conservation stages. California's MWELO applies to larger new/renovated landscapes.

Rohnert Park enforces a property-maintenance/weed-abatement code requiring owners to control overgrown grass, weeds and vegetation as a fire and nuisance hazard. Violations can lead to abatement and a cost lien.

Owners may remove trees on private property in Rohnert Park; removal of street trees or protected trees requires city approval, and replacement may be required during development.

Owners maintain trees on their own property in Rohnert Park; street trees and trees in the public right-of-way are managed by the city, which requires approval before pruning or removing them.

Sonoma County encourages rainwater capture. Simple rain barrels for outdoor irrigation generally need no permit, but systems that collect rainwater for potable (indoor) use require a permit under Appendix K of the California Plumbing Code, which the County adopted in January 2017. Related graywater systems have their own tiered permit rules.

Sonoma County does not mandate native plants for private yards. For projects subject to its Water Efficient Landscape Ordinance (Code Chapter 7D3), landscapes must meet a water budget that favors low-water, climate-appropriate planting. Voluntary programs like Russian River-Friendly Landscaping promote natives but are not legally required.

Under California SB 1383 (effective Jan 1, 2022), all Sonoma County residents and businesses must keep organic waste - food scraps and yard trimmings - out of the landfill, typically by using the green organics cart. Backyard home composting is encouraged and can reduce what you set out. The mandate is a state law implemented locally by Zero Waste Sonoma.

Sonoma County Code Chapter 13A declares hazardous vegetation and combustible material on unincorporated parcels a public nuisance. Owners must abate it - including cutting dry grasses and creating defensible space to 100 feet around structures. The County can inspect, order abatement, and lien properties for unpaid costs.

As of late 2025 there is no ban on artificial turf in unincorporated Sonoma County, but the County has raised environmental and health concerns and directed staff to develop a model ordinance that could let jurisdictions consider a moratorium. Installations tied to permitted projects must still satisfy the County's Water Efficient Landscape Ordinance.

Home-occupation signage in Rohnert Park is tightly limited by the zoning sign rules — typically a single small, non-illuminated sign, if any, in residential zones.

Home occupations in Rohnert Park must not generate traffic, parking demand or deliveries beyond what is normal for a residence; significant customer visits can disqualify the use.

Home occupations in Rohnert Park are permitted as an accessory use under zoning with a home-occupation permit/business license, subject to conditions keeping the business subordinate to the residence.

Since Ordinance No. 6363 (2021), unincorporated Sonoma County no longer requires a zoning permit for a qualifying home occupation under Zoning Code Section 26-88-121. Operators must instead meet by-right standards on customers, hours, deliveries, and vehicles.

California's Homemade Food Act (HSC 113758) lets residents make approved non-perishable foods at home. In Sonoma County, Class A operations self-register and Class B operations get an inspected permit, both through the County Department of Health Services Environmental Health.

California law (HSC 1597.45-1597.46, as amended by SB 234) makes small and large family daycare homes a residential use by right. Sonoma County cannot require a use permit or impose a business license, fee, or tax to operate one; the state licenses providers.

Above-ground pools holding more than 18 inches of water in Rohnert Park require a building permit and the same barrier protection as in-ground pools; ladders must be removable or secured when unattended.

Pools in Rohnert Park must be enclosed under the California Building Code and Swimming Pool Safety Act: a barrier at least 60 inches (5 feet) high with self-closing, self-latching gates, plus at least one additional drowning-prevention feature.

Pool construction in Rohnert Park must meet the California Building Code and Swimming Pool Safety Act — barriers, anti-entrapment drain covers, and electrical bonding. A building permit and inspections are required.

In unincorporated Sonoma County, a building permit from Permit Sonoma is required for in-ground pools and spas. Plans must be prepared by a California-licensed civil or structural engineer and include fencing, drainage, and soils details under Permit Sonoma guideline CNI-044.

Permit Sonoma treats spas and hot tubs holding water deeper than 18 inches as swimming pools under guideline CNI-044, so a permit and the California Pool Safety Act's two-feature barrier rules apply. Many portable spas with locking covers can satisfy a safety feature.

Rohnert Park participates in the National Flood Insurance Program and enforces floodplain-development standards in FEMA-mapped special flood hazard areas near the Laguna de Santa Rosa and local creeks. Building in a flood zone requires elevation to or above base flood elevation.

Sonoma County operates under two separate Municipal Separate Storm Sewer System (MS4) NPDES permits - one issued by the North Coast Regional Water Quality Control Board for the Russian River basin and one by the San Francisco Bay Regional Water Quality Control Board for southern Sonoma County. Chapter 11 of the Sonoma County Code prohibits discharge of any pollutant (including muddy construction runoff) to the storm-drain system or waters of the state. Development and redevelopment projects must implement Low-Impact Development (LID) post-construction stormwater controls.

Sonoma County Code Chapters 11 and 11A require construction-grading permits and Erosion Prevention and Sediment Control plans for almost any ground-disturbing work. During the October 15 - May 15 wet season, no more than 1 acre or 20% of the permitted work area (whichever is greater) may have erodible soil exposed at any time, and best management practices (BMPs) must be functional whenever the National Weather Service forecasts a 30% or greater chance of rain within 24 hours - in any season. Sonoma's hillside and vineyard/orchard grading rules (Chapter 36 VESCO) add further restrictions on slopes over 10%.

The California Coastal Act, Public Resources Code sections 30000 through 30900, requires Coastal Development Permits for nearly all work in the coastal zone and gives the Coastal Commission appeal jurisdiction over local decisions.

Gas, propane, and electric barbecues are generally allowed in unincorporated Sonoma County and are not subject to the wood-smoke burn bans that can apply on Winter Spare the Air days. The California Fire Code adopted in County Code Chapter 13 sets clearance and safety expectations, and in Very High fire zones grills should be kept well clear of vegetation and structures.

Wood- and charcoal-fired smokers used for cooking are generally allowed in unincorporated Sonoma County and are not regulated as the open burning of vegetation. However, in the BAAQMD portion of the County, wood smoke is restricted on Winter Spare the Air Alert days, and all solid-fuel cooking carries wildfire risk that triggers Fire Code clearance and defensible-space caution.

Building setbacks in unincorporated Sonoma County are set by each zoning district in Chapter 26. In the R1 Low Density Residential district, the front yard must be at least 20 feet (and no structure closer than 45 feet to a road centerline), side yards at least 5 feet, and rear yards at least 20 feet. Other districts have different yards.

Maximum building height in unincorporated Sonoma County is set by each zoning district. In the R1 Low Density Residential district, the main building may be up to 35 feet and accessory buildings up to 15 feet, with additional height allowed only if a use permit is first secured. Other zones set their own limits.

Maximum lot coverage in unincorporated Sonoma County is set by zoning district. In the R1 Low Density Residential district, buildings may cover no more than 40% of the lot, with a minimum lot size of 6,000 square feet and minimum average lot width of 60 feet. Swimming pools may be exempted from coverage by the planning director.

Removing protected native trees in unincorporated Sonoma County requires a permit under the Tree Protection Ordinance (Code 26-88-010): a zoning permit for native species 6 inches DBH or larger, and a use permit for hardwoods 36 inches+ and redwoods 48 inches+. Valley oaks in a Valley Oak Habitat Combining Zone and Heritage/Landmark trees (Chapter 26D) get extra protection.

California provides statewide protections for native oak woodlands and heritage trees through CEQA review, Public Resources Code, and Forest Practice Rules that apply uniformly.

In unincorporated Sonoma County, Permit Sonoma's Code Enforcement Division responds to complaints about junk, debris, and substandard property. Violations are typically declared public nuisances and must be abated, usually within 30 days, under the County Code's administrative enforcement procedures.

Unincorporated Sonoma County residents receive three weekly-collected carts (gray garbage, blue recycling, green compost) from franchised hauler Recology Sonoma Marin. Carts come in 20-, 32-, 64-, and 96-gallon sizes and must not be overstuffed; loose material set out without prior arrangement is not collected.

Under Sonoma County Code Chapter 13A, hazardous vegetation and combustible material on unimproved (vacant) parcels in unincorporated areas is a declared public nuisance. Owners must clear flammable growth within 10 feet of structures and roadway frontage and may face County abatement with cost recovery.

Sonoma County Code Chapter 13A requires year-round defensible space in unincorporated areas. On improved parcels, owners must keep grass cut to 6 inches or less and maintain a 30-foot defensible space; the County Fire Warden can order abatement and recover costs as a property lien.

Sonoma County publishes no specific garage-sale permit ordinance for unincorporated areas, and operating a business in the unincorporated county does not require a county business license. Occasional household yard sales are generally treated as incidental residential activity, not a regulated business use.

Unincorporated Sonoma County uses franchised solid-waste collection, primarily by Recology Sonoma Marin. Garbage, recycling, and compost carts are collected weekly. Carts should be at the curb the night before, since collection begins early in the morning.

Recology Sonoma Marin sets cart placement standards for unincorporated Sonoma County: carts no more than 2 feet from the curb, 3 feet from other carts or structures, 12 feet of vertical clearance, lid arrows facing the street, and clear of obstructions like parked cars and hydrants.

Unincorporated Sonoma County residents served by Recology Sonoma Marin get appointment-based bulky item pickup at no cost. Mattresses, appliances, furniture, bagged or bundled excess yard debris, and electronics qualify; schedule by contacting the hauler directly.

Recycling in Sonoma County is driven by California law. AB 341 requires recycling by businesses and multifamily complexes of 5+ units generating 4+ cubic yards/week. Unincorporated residents recycle through Recology's blue cart; organics and recyclables must be kept out of the landfill.

California's SB 1383 makes it unlawful to throw food waste in the garbage. In unincorporated Sonoma County, residents must separate organics into the green cart serviced by Recology Sonoma Marin or self-haul to a permitted facility. Tiered businesses must also recover edible food.

In unincorporated Sonoma County, campaign signs may be erected no earlier than 90 days before an election and must be removed within 20 days after the close of the campaign, per the County Registrar's campaign guide and Chapter 26 Article 84 design standards. State law (B&P Code 5405.3) caps temporary political signs at 32 sq ft.

Garage and yard sale signs in unincorporated Sonoma County are temporary signs governed by Article 84 (Sign Regulations) of the County Zoning Ordinance, Chapter 26 (Secs. 26-84 series). Signs must follow Article 84 size and placement standards and may not be posted in public rights-of-way or on utility poles.

Unincorporated Sonoma County has no single countywide dark-sky ordinance for all properties, but its Zoning Regulations (Chapter 26) require fully shielded, downward-cast lighting for many uses. For example, ADU and certain special-use standards require fully shielded, downward-facing fixtures and prohibit floodlights and uplights.

Sonoma County's Zoning Regulations (Chapter 26) address light spillover onto neighboring properties through use-specific standards and design review rather than a single trespass ordinance. Regulated uses must use fully shielded, downward-cast lighting so it does not wash onto other properties, and certain uses cap illuminance at the property line.

Unincorporated Sonoma County does not have a stand-alone juvenile-curfew ordinance applicable countywide. A 1997 proposal by the Board of Supervisors to impose an 11:00 p.m. weeknight and midnight weekend curfew on minors in unincorporated areas was debated but was not adopted as standing County code. Several Sonoma County cities have their own curfew ordinances (e.g., Santa Rosa Municipal Code Ch. 9-12, Petaluma Municipal Code 9.16, Sonoma Municipal Code), and California Welfare & Institutions Code Sec. 625.5 allows but does not require local curfew laws.

Sonoma County Regional Parks are open from 7 a.m. to sunset; parking lots and entry gates close when the parks close at sunset. Remaining in a park after closing is restricted under the County's park rules (Code of Ordinances Chapter 20, Parks and Recreation). Overnight use is limited to designated campgrounds.

On September 17, 2024, the Sonoma County Board of Supervisors adopted Ordinance No. 6496, the Residential Tenancy Protections Ordinance, which applies to rental units in unincorporated Sonoma County. The ordinance augments the statewide California Tenant Protection Act (AB 1482, Cal. Civ. Code § 1946.2) by extending just-cause protections from day one of any covered tenancy, expanding coverage to income-restricted housing, narrowing the rent-nonpayment trigger, and increasing no-fault relocation payments.

Unincorporated Sonoma County does NOT have a local rent control ordinance. The 2024 Residential Tenancy Protections Ordinance (Ord. 6496) added eviction protections but did not adopt a local rent cap. The only annual rent-increase cap covering most Sonoma County tenants is California's statewide Tenant Protection Act (AB 1482), codified at Cal. Civ. Code § 1947.12, which limits increases to 5% + the regional CPI, with a 10% hard ceiling.

California evictions run through the unlawful detainer process. Under Code of Civil Procedure § 1161, nonpayment requires a 3-day notice to pay rent or quit (excluding weekends and holidays), and lease violations require a 3-day notice to cure or quit. No-fault terminations of covered tenancies require 30, 60, or 90 days. Self-help lockouts are illegal.

California landlords must keep rentals fit to live in. Civil Code §§ 1941 and 1941.1, reinforced by Green v. Superior Court, imply a warranty of habitability covering plumbing, heat, water, electricity, and sanitation. If repairs fail after notice, a tenant may repair and deduct up to one month's rent under § 1942 or withhold rent.

California Civil Code § 1954 limits when a landlord may enter a rented home. Except in emergencies, abandonment, or with tenant consent, the landlord must give reasonable written notice (24 hours is presumed reasonable) and may enter only during normal business hours, for specific permitted reasons such as repairs, inspections, or showings.

California sets no fixed dollar or percentage cap on rent late fees, but a late fee in a residential lease is treated as liquidated damages. Under Civil Code § 1671, such a fee is valid only if it reasonably estimates the landlord's actual loss from late payment; arbitrary penalty fees are unenforceable.

To end a California month-to-month tenancy, a tenant gives 30 days' written notice. A landlord gives 30 days if the tenant has lived there under a year, or 60 days if a year or more, under Civ. Code § 1946.1. AB 1482 requires just cause after 12 months; military and DV tenants may exit early.

California requires written notice before raising a month-to-month tenant's rent. Under Civ. Code § 827, increases of 10% or less in 12 months need 30 days' notice; increases above 10% need 90 days' notice. AB 1482 separately caps yearly increases on covered units.

As of July 1, 2024, California landlords may collect no more than one month's rent as a security deposit, regardless of whether the unit is furnished. The deposit, minus any lawful deductions, must be returned with an itemized statement within 21 days after move-out, or the landlord risks penalties of up to twice the deposit.

California adverse possession requires five years of continuous, open, hostile possession AND payment of all property taxes during that period under Code of Civil Procedure § 325. A squatter or trespasser who has not paid taxes gains no ownership and can be removed by unlawful detainer, ejectment, or a police trespass action.

Health and Safety Code section 11362.2 grants every adult 21 or older the statewide right to cultivate up to six cannabis plants indoors, and bars local governments from completely prohibiting indoor personal cultivation.

Commercial drone operations in California follow uniform federal rules under 14 CFR Part 107 plus statewide California provisions in Civil Code 1708.8 and Public Utilities Code 21401, with local rules limited to ground-based regulation.
