Petaluma Municipal Code Section 9.08.130 (Animals at Large) requires dogs off the owner's property to be on a leash not exceeding six feet held by a person capable of controlling the dog. Dogs cited for being at large and over six months old must be spayed or neutered and microchipped at the owner's expense. Section 9.08.180 covers excessive barking and other animal noise.
California Fish & Game Code §251.3 prohibits intentional feeding of big-game mammals (deer, elk, bears). Petaluma Code §9.08.100 regulates straying of domestic birds and livestock that can attract predators.
Petaluma Code §9.08.040 prohibits keeping live hogs, pot-bellied pigs (above limits), and swine in residential areas. Chapter 9.12 requires permits for livestock.
California prohibits breed-specific bans, so Petaluma 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 Petaluma 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 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.
Petaluma is declared a 'quiet city' by IZO §21.040. No person may cause a source of sound that, when measured at the affected property line in open/outdoor space, exceeds the dBA limits in Table 21.1.
California Vehicle Code §27150–27207 sets statewide muffler and exhaust noise standards that Petaluma Police enforce; modified or excessive vehicle noise is also captured by IZO §21.040's general noise standard.
Persistent dog barking in Petaluma is enforced under the noise ordinance and animal provisions as a disturbance; chronic barking that disturbs neighbors can be cited.
Construction noise in Petaluma is limited to daytime hours under the noise ordinance — generally 7 a.m.–7 p.m. weekdays with more limited weekend hours and none on Sundays/holidays. Work outside the permitted window is a violation; confirm exact hours with the city.
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.
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.
Petaluma IZO §7.110 requires a Short-Term Vacation Rental Permit issued by the Planning Director (or designee) for any STR. STRs are allowed only in residential, planned unit development, and mixed use zoning districts.
Petaluma Code Ch. 4.24 levies a Transient Occupancy Tax at 10% on accommodations rented for fewer than 30 days within City limits.
IZO §7.110 limits maximum overnight occupancy and imposes operational standards on STRs including parking, trash, and noise compliance.
STR guests in Petaluma are bound by the noise ordinance — loud or disturbing noise, especially at night, can be cited.
STR guest parking must comply with Petaluma zoning off-street parking standards; on-street parking is limited and subject to the city vehicle code.
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.
Petaluma adopts the California Fire Code via PMC §17.20.050 with local amendments. Open burning is generally prohibited; small recreational fires require compliance with CFC §307 setbacks and local Sonoma County Air District rules.
Petaluma adopts California Residential Code §R314 and §R315 via PMC §17.04.020, requiring smoke alarms in every sleeping room, outside sleeping areas, and on each story, and CO alarms outside sleeping areas in dwellings with fuel-burning appliances or attached garages.
Possession, sale, use, or discharge of fireworks of any kind (including 'safe and sane') is prohibited within the City of Petaluma under PMC §17.20.070 and Ch. 10.65.
Portions of Petaluma fall within CAL FIRE-mapped Fire Hazard Severity Zones (FHSZ). Properties in 'Very High' FHSZ are subject to PRC §4291 (state) and PMC §17.20.050 (local) defensible-space and ignition-resistant construction standards.
Open burning in Petaluma is regulated by the Bay Area Air Quality Management District and the fire department; residential yard-waste burning is generally prohibited and barred on Spare the Air days. Wildfire risk drives strict enforcement.
Petaluma adopts the California Fire Code defensible-space rules via PMC §17.20.050. Property owners in the wildland-urban interface (WUI) must maintain at least 30 feet of defensible space around all buildings and structures.
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.
Under California Vehicle Code §22651(k) and PMC Ch. 11.44/11.64, a vehicle that remains parked on a public street for more than 72 consecutive hours can be tagged, cited, and towed as an abandoned vehicle.
Petaluma Code §11.44.120 prohibits parking commercial vehicles in residential districts except while actively loading/unloading or performing services on properties in the same block.
RV, trailer and boat storage on residential lots in Petaluma is regulated by zoning, which restricts placement (typically a paved area) and prohibits living in a parked RV.
Driveway approaches in Petaluma require an encroachment permit and must meet city standards; vehicles generally must be parked on an approved paved surface, not on the lawn.
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.
Petaluma IZO §13.020 and Table 13.1 set fence height by zoning district setback. Generally 6 feet in interior side and rear yards and 3 feet in front-yard setbacks for residential R-1 through R-5 districts.
Petaluma IZO §13.040 sets standards for fence materials. Barbed wire and razor wire are prohibited in residential zones; chain-link is restricted in front yards.
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).
A building/zoning permit is generally required in Petaluma for fences over 6 feet or for masonry/retaining walls; pool barrier fences must meet the California Building Code. Standard residential fences at the height limit may be permit-exempt.
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.
Under California Gov Code §65852.2(e), Petaluma must approve conversion of an existing garage to an ADU and may not require replacement parking even if the conversion eliminates required parking.
Petaluma IZO §7.030 implements California's permissive ADU laws (Gov Code §65852.2). Most single-family lots may build at least one ADU and one Junior ADU.
Sheds in Petaluma must meet zoning setback rules for accessory structures. Under the California Building Code, a building permit is generally required for sheds over 120 square feet; smaller sheds still must meet placement rules.
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.
IZO §7.050 requires a Home Occupation Permit for any home-based business in Petaluma residential zones. The business must be clearly secondary to residential use and not change the residential character of the neighborhood.
Petaluma IZO §7.050 limits home-occupation traffic such that pedestrian, automobile, or truck traffic and parking in residential neighborhoods do not exceed that normally associated with residential use, with no more than two non-occupant vehicles present on the street at any given time.
Home-occupation signage in Petaluma is tightly limited by the zoning sign rules — typically a single small, non-illuminated sign, if any, in residential zones.
Home occupations in Petaluma 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 Petaluma 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.
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.
Petaluma Code §15.17.050 implements California's Model Water Efficient Landscape Ordinance (MWELO). New and rehabilitated landscapes must meet ETo-based water budgets and use approved plant palettes.
Owners maintain trees on their own property in Petaluma; street trees and trees in the public right-of-way are managed by the city, which requires approval before pruning or removing them. Petaluma has a tree-protection ordinance for certain trees.
Petaluma's tree-protection ordinance requires a permit to remove protected or heritage trees, even on private property; street-tree removal requires city approval. Replacement plantings may be required.
Petaluma 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.
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.
Pools in Petaluma 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 Petaluma 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.
Above-ground pools holding more than 18 inches of water in Petaluma require a building permit and the same barrier protection as in-ground pools; ladders must be removable or secured when unattended.
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.
Petaluma IZO Ch. 6 (Floodplain Management) regulates development in FEMA-mapped Special Flood Hazard Areas. The Petaluma River corridor and downtown lowlands include extensive 100-year floodplain.
Petaluma Code Ch. 15.80 prohibits discharge of pollutants to the City's MS4 storm drain system. Illicit connections and prohibited discharges are violations subject to administrative and civil penalties.
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.
California Civil Code §714 (Solar Rights Act) preempts HOA restrictions on solar energy systems. Restrictions that significantly increase cost (over $1,000 for solar water heating; over 10% of installed cost for PV) or significantly decrease efficiency (over 10%) are void.
California's Solar Rights Act and the SolarAPP+ mandate (SB 379) require expedited permit review of small residential solar systems, preempting restrictive local processes.
Petaluma Code provisions and California Penal Code §374.3 prohibit dumping of trash, debris, or hazardous materials on public or private property without permission. Petaluma reports dump sites to Sonoma County Hazmat for cleanup.
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.
Petaluma Code Ch. 10.52 establishes a juvenile curfew making it unlawful for minors under 18 to be in public places during specified late-night hours without a parent, guardian, or recognized exception.
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.
Petaluma IZO §21.040 includes standards prohibiting glare and light trespass onto adjacent properties. Outdoor lighting must be shielded and directed downward.
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.
Petaluma does not have a local rent-control ordinance. Statewide California Civil Code §1947.12 (AB 1482, Tenant Protection Act) caps annual rent increases at 5% plus CPI (max 10%) for covered units.
California Civil Code §1941.1 establishes the warranty of habitability — landlords must maintain rental units in livable condition including waterproofing, plumbing, heat, electric, sanitary fixtures, and pest-free conditions. Petaluma Code Enforcement assists tenants with municipal code violations.
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.
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 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.
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.
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.
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.
Recreational drone flight in California is governed primarily by FAA regulations under 14 CFR Part 107 and 49 USC 44809, with state-level rules added by Civil Code 1708.8 and Government Code 853 applying uniformly statewide.
California sets a statewide minimum wage floor under Labor Code 1182.12, currently $16.50 per hour for all employers as of 2025. Local governments are not preempted and may set higher minimums; many cities exceed the state rate substantially.
California's Healthy Workplaces, Healthy Families Act under Labor Code 245-249 mandates paid sick leave for nearly all employees statewide. SB 616 (2023) raised the minimum to 40 hours or five days annually effective January 2024, applying universally.
California regulates concealed carry weapons licenses statewide under Penal Code 26150 through 26225. Senate Bill 2 (2023) imposes uniform sensitive-place restrictions and applicant standards, preempting local variations on issuance criteria and qualifications.
California preempts most local firearm regulation under Government Code 53071 and Penal Code 25605, reserving licensing, registration, and manufacture authority to the state. However, local governments retain limited authority over discharge, sensitive places, and zoning of gun businesses.
California broadly prohibits open carry of firearms statewide under Penal Code 25850 (loaded firearms in public) and Penal Code 26350 (open carry of unloaded handguns). The prohibition applies uniformly across all California cities and counties without local variation.
California prohibits carrying loaded firearms in vehicles statewide under Penal Code 25400 and 25850. Unloaded handguns transported in private vehicles must be in a locked container or the vehicle's locked trunk; long guns must be unloaded but need not be locked.

California HOAs may fine members for rule violations, but only under a published schedule of fines and after strict due-process steps.
