Trabuco Canyon, CA

Under California SB 1383, effective January 1, 2022, residents in unincorporated Orange County must separate organic waste (food scraps, yard trimmings, food-soiled paper) from trash. Jurisdictions must provide organic collection. Backyard composting is encouraged and can reduce a household's reliance on collection.

Unincorporated Orange County runs an annual Weed Abatement Program under California Health & Safety Code Sections 14875-14922. The Board of Supervisors declares hazardous weeds a public nuisance; owners must clear vegetation, litter, and flammable material by the noticed deadline or face County abatement billed to their tax bill.

Capturing rooftop rainwater is legal in unincorporated Orange County, governed mainly by California's Rainwater Capture Act of 2012. No state water-rights permit is needed for rooftop capture used outdoors for non-potable purposes; standard rain barrels and small cisterns generally need no plumbing permit.

Unincorporated Orange County does not require native or drought-tolerant plants, but the County's Water Efficient Landscape Ordinance (adopted March 14, 2016) implements California's MWELO, limiting turf and favoring low-water plants on qualifying new and rehabilitated landscapes. State Civil Code 4735 protects low-water landscaping from HOA bans.

Unincorporated Orange County has no countywide ban on artificial turf. Synthetic lawns are treated as a landscaping/site-development matter and may need a permit if part of qualifying construction. California Civil Code 4735 bars HOAs from prohibiting artificial turf that resembles grass.

Unincorporated Orange County does not set a single countywide watering schedule; outdoor water rules are set by each retail water district (coordinated through MWDOC) plus statewide law. California permanently prohibits wasteful practices like runoff, hosing pavement, and using non-recirculating fountains under State Water Board rules.

Unincorporated Orange County has no general turf-height limit for maintained lawns, but dry grass, weeds, and rank vegetation that become a fire menace are abated under the County's Weed Abatement Program using California Health & Safety Code authority. State defensible-space guidance caps annual grasses at 4 inches.

For ordinary trees on private property in unincorporated Orange County, routine pruning needs no county permit. The County's fire program may require trimming branches within 10 feet of a roof, chimney, or stovepipe. A draft native-tree rule, if applied, would treat excessive pruning of protected trees as damage.

Unincorporated Orange County has not adopted a general native-tree preservation ordinance, so most private tree removal needs no county permit. A draft Protected Tree framework would require permits and 5:1 replacement, but it remains a proposal limited to large parcels in specific-plan canyon areas.

Vehicle noise on public roads in unincorporated Orange County is governed mainly by California state law, not the County code. The California Vehicle Code requires adequate mufflers, bars modified or amplified exhaust, and treats a sound level over 95 dB(A) for light vehicles as non-compliant.

Industrial and commercial machinery in unincorporated Orange County is regulated as a 'fixed noise source' under the Codified Ordinances. Such equipment must keep noise at neighboring residential property within the Section 4-6-5 limits (55 dB(A) day, 50 dB(A) night), with graduated duration allowances.

Aircraft noise is not regulated by Orange County's local noise code. The County ordinance defers to preempting State and Federal law (Sec. 4-6-7(j)), and aircraft and airspace noise is controlled by the FAA, while California regulates airport-proprietor noise standards.

Unincorporated Orange County does not set a single citywide curfew clock. Instead, Division 6 of Title 4 of the Codified Ordinances sets quieter nighttime exterior noise limits from 10:00 p.m. to 7:00 a.m. (50 dB(A)) than during the day (55 dB(A)), so the practical 'quiet hours' run overnight.

In unincorporated Orange County, construction, repair, remodeling, and grading are exempt from the noise limits only if they do NOT take place between 8:00 p.m. and 7:00 a.m. on weekdays including Saturday, or at any time on Sunday or a Federal holiday, under Codified Ordinances Section 4-6-7(e).

Unincorporated Orange County has no separate leaf-blower ordinance. Leaf blowers fall under the County noise code's property-maintenance hours (Sec. 4-6-7(i)), and statewide California law (AB 1346 / CARB) now bars sales of new gas-powered leaf blowers and other small off-road engines.

Unincorporated Orange County regulates barking dogs through OC Animal Care, not the dB-based noise code. A 'barking dog' is one that barks, bays, cries, or howls for an extended period disturbing any person: incessantly for 30 minutes or more, or intermittently totaling 60 minutes or more, in any 24-hour period.

Unincorporated Orange County uses a dB(A)-based noise code. Exterior residential limits are 55 dB(A) (7 a.m.-10 p.m.) and 50 dB(A) (10 p.m.-7 a.m.); interior limits are 55 dB(A) day and 45 dB(A) night, with graduated time allowances under Codified Ordinances Sections 4-6-5 and 4-6-6.

Outdoor music in unincorporated Orange County must meet the music-reduced noise limits (about 50 dB(A) day, 45 dB(A) night at neighboring homes), and organized outdoor gatherings, public dances, and shows are exempt only when conducted under a County license per Codified Ordinances Section 4-6-7(b).

In unincorporated Orange County, amplified music is treated harshly under the noise code: because music is an enumerated noise type, the exterior limits in Section 4-6-5 drop by 5 dB(A) to 50 dB(A) by day and 45 dB(A) at night. Public dances and shows need a County license.

Orange County's short-term rental ordinance (Zoning Code Section 7-9-93) for unincorporated areas does NOT require the home to be the owner's primary residence. Non-owner-occupied whole-home rentals are allowed with a permit. The only residency-style restriction is that Accessory Dwelling Units cannot be used as short-term rentals.

Orange County's short-term rental ordinance (Zoning Code Section 7-9-93) does NOT require the host to be present during stays in unincorporated areas. Unhosted, whole-home rentals are permitted. The ordinance instead requires a 24/7 reachable owner or designee contact and guest-responsibility records.

Orange County may revoke a short-term rental operator permit after repeated nuisance, noise, or occupancy violations at the same property. The county uses a graduated enforcement approach with warnings, fines, and ultimately permit revocation for habitual offenders.

Hosting platforms like Airbnb and VRBO are expected to display valid OC short-term rental permit numbers on listings and may face liability for facilitating unpermitted rentals in unincorporated Orange County. The county can pursue platform-level enforcement when listings lack permits.

Orange County does not impose a separate extended home-share category for partial-unit rentals exceeding hosted-only night caps. All short-term rentals in unincorporated areas operate under a single STR operator permit regime regardless of duration.

Hosts in unincorporated Orange County must apply for a Short-Term Rental Permit through myOCeServices.ocgov.com and submit a use letter, floorplan, blank lease, and proof of ownership. Permits must be renewed every two years under Zoning Code Section 7-9-93, and a change in ownership terminates the permit.

Unincorporated Orange County requires a Short-Term Rental Permit, approved by the OC Development Services Director, before renting any dwelling unit for fewer than 30 days. The rule is codified at Orange County Zoning Code Section 7-9-93 and applies in single-family, multifamily, and certain commercial districts. Accessory Dwelling Units may not be used as short-term rentals.

Short-term rental guests in unincorporated Orange County must observe quiet hours under Zoning Code Section 7-9-93, which incorporates the County Noise Control Ordinance (Section 4-6-5). Continuous exterior noise is capped at 55 decibels from 7 a.m. to 10 p.m. and 50 decibels from 10 p.m. to 7 a.m. in residential areas.

Orange County's short-term rental ordinance (Zoning Code Section 7-9-93) sets NO annual cap on the number of nights a property may be rented and no minimum-stay rule beyond the under-30-day definition in unincorporated areas. The County limits vehicles, occupancy, and noise instead of capping rental nights.

Zoning Code Section 7-9-93 requires unincorporated Orange County short-term rentals to provide at least two off-street parking spaces (garage and/or driveway) at all times. Vehicles are capped at one per one-bedroom unit, or two for units with two or more bedrooms, unless the Director allows more.

Under Zoning Code Section 7-9-93, overnight occupancy of an unincorporated Orange County short-term rental is capped at two persons per bedroom plus two additional persons. The Director may approve a higher number case-by-case. Maximum occupancy and a violation notice must be posted inside the unit and in the lease.

Orange County's short-term rental ordinance (Zoning Code Section 7-9-93) does NOT require hosts in unincorporated areas to carry liability insurance as a permit condition. No minimum coverage amount is set by the County code. Hosts should still consider private STR or homeowners coverage and check platform requirements.

Operators in unincorporated Orange County must collect a 10% Transient Occupancy Tax (TOT) on stays of 30 days or less, remitted quarterly to the OC Treasurer-Tax Collector, and obtain a TOT certificate. The zoning Short-Term Rental Permit application fee is reported at $250, renewed every two years.

Smoke alarm requirements in unincorporated Orange County come from California law, not a separate county ordinance. Health & Safety Code 13113.7 requires State Fire Marshal-approved smoke alarms in every dwelling unit - in each sleeping room, in hallways adjacent to bedrooms, and on each story - and triggers an upgrade when a building permit over $1,000 is issued.

Backyard recreational fires are allowed in unincorporated Orange County under the California Fire Code, subject to OCFA limits: a fuel pile no larger than 3 feet across and 2 feet high, at least 25 feet from any structure, constant attendance, and a ban during high winds (over 8 mph), low humidity (under 25%), Red Flag conditions, or AQMD no-burn days.

Propane storage in unincorporated Orange County follows the California Fire Code (Chapter 61), enforced by OCFA. Portable LP-gas containers (like 20-lb BBQ tanks) may not be stored in basements, pits, or below-grade spaces where heavy gas can collect. Larger installations have separation distances from buildings and lot lines, and permits apply above set thresholds.

OCFA, which serves all unincorporated Orange County, follows the California Fire Code. Recreational fire pits must stay at least 25 feet from any structure, with a fuel pile no more than 3 feet across and 2 feet high. Outdoor wood/solid-fuel fires are banned when winds exceed 8 mph and humidity is below 25%, or during Red Flag conditions.

In unincorporated Orange County, ALL fireworks - including state-approved 'Safe and Sane' fireworks - are illegal to use. Unincorporated communities are not among the 10 OC cities that license retail sales, so any use of consumer fireworks here is prohibited under the California Fireworks Law (Health & Safety Code 12500 et seq.).

In wildfire-prone unincorporated Orange County, owners must maintain defensible space around structures. California Public Resources Code 4291 requires clearance up to 100 feet around buildings, and CAL FIRE's defensible-space framework defines Zone 0 (0-5 ft, ember-resistant), Zone 1 (5-30 ft) and Zone 2 (30-100 ft). OCFA administers inspections in OC's high-hazard areas.

Open burning of residential yard waste, leaves, and tree trimmings is effectively prohibited across Orange County. South Coast AQMD Rule 444 and the 'Check Before You Burn' program (AQMD Rule 445) sharply restrict open and wood burning, and the California Fire Code requires a permit and bans open burning whenever atmospheric or local conditions make it hazardous.

Much of unincorporated Orange County - especially the Silverado, Modjeska, and Trabuco canyon communities - lies in CAL FIRE-designated Very High, High, or Moderate Fire Hazard Severity Zones. CAL FIRE released an updated FHSZ map for OC's unincorporated areas in 2025. Properties in these zones face stricter defensible-space, building, and disclosure requirements.

In unincorporated Orange County, any commercial vehicle over 25 feet long, 8 feet high, or 90 inches wide is barred from residential property under Codified Ordinance Sec. 3-13-4(15). On public streets, CVC 22507 lets the county restrict parking of vehicles six feet or more in height within 100 feet of an intersection, once signs are posted.

Orange County's Zoning Code Sec. 7-9-70.8 requires non-residential uses to provide off-street loading spaces, scaled by floor area - for example one loading space at 7,500-14,999 sq ft, rising to six spaces at 80,000-100,000 sq ft. On public streets, yellow and white painted curbs designate loading zones under California Vehicle Code 21458.

Curb colors in unincorporated Orange County follow California Vehicle Code 21458: red means no stopping, standing, or parking; yellow is for loading freight/passengers; white is for passenger loading; green is time-limited parking set by local ordinance. Only the local authority may paint or designate these curb markings - residents cannot paint curbs to reserve parking.

In unincorporated Orange County, RVs, campers, trailers, and boats/watercraft may be stored on residential property only on a paved area outside the required building setback abutting a public street AND screened by a 6-foot opaque fence or wall, OR on a paved driveway connecting the garage/carport to the street. Storage on any unpaved surface is prohibited.

In unincorporated Orange County, Codified Ordinance Sec. 3-13-4(15) makes it unlawful to keep or store in any residential zone (or on residentially-developed property) construction or business equipment, commercial containers, buses, tow trucks, dump trucks, flatbed trucks, tractors, tractor-trailers, truck trailers, or any commercial vehicle over 25 feet long, 8 feet high, or 90 inches wide.

In unincorporated Orange County, electric vehicle charging stations are addressed by Zoning Code Sec. 7-9-107, which requires that they be installed and operated in compliance with the applicable California Building Code(s) and be approved by the Building Official. New multifamily and nonresidential projects must also provide EV-ready parking under the California Green Building Standards Code (CALGreen).

In unincorporated Orange County, keeping any abandoned, wrecked, dismantled, or inoperative vehicle (or part) on private property is prohibited except as allowed by Table 3-13-6(c) of Codified Ordinance Sec. 3-13-4(11). On public streets, a vehicle left 72+ hours can be removed under CVC 22651(k), and the state abatement framework (CVC 22660) applies.

Orange County's Zoning Code Sec. 7-9-70.3 sets residential driveway standards: a single-family driveway must be paved at least 10 feet wide from the street/alley to the garage maneuvering area. Vehicles and RVs may be stored on a paved driveway connecting a garage/carport to the street, but driveways may only serve approved parking areas.

Unincorporated Orange County does not impose a blanket overnight on-street parking ban; on public streets the California Vehicle Code controls. A vehicle may not be left standing on a street for 72 or more consecutive hours, after which it can be cited and towed under CVC 22651(k). Posted local signs may add stricter overnight or time-limit rules.

On public streets in unincorporated Orange County, parking is primarily governed by the California Vehicle Code, enforced by the Orange County Sheriff. State law lets the county restrict parking by ordinance and now bars 'daylighting' parking within 20 feet of a marked or unmarked crosswalk (AB 413). Curb-color rules under CVC 21458 also apply.

Unincorporated Orange County fences must comply with Zoning Code Section 7-9-64: height limits by setback area, a 3.5-foot cap in sight-visibility triangles at driveways and intersections, no chain-link in front setbacks, and a building permit for fences or walls over six feet. Swimming-pool fencing has separate state safety rules.

Most fence materials are allowed in unincorporated Orange County so long as height and sight-line rules in Zoning Code Section 7-9-64 are met. The only material rule in that section bars chain-link in a required front setback. Walls over six feet must be engineered through a building permit.

Orange County enforces the California Swimming Pool Safety Act (Health & Safety Code §115920-115929) and adopted Ordinance No. 19-006 requiring both primary and secondary pool barriers for all residential pools in unincorporated areas with water depth exceeding 18 inches.

In unincorporated Orange County, solid fences are capped at 3.5 feet in a required front setback and 6 feet in side and rear setbacks. Open fencing may reach 5 feet in front. Heights up to 8 feet are possible by permit, and fences taller than that need a Use Permit.

OC Development Services requires a building permit for any fence or wall over six feet tall (over 42 inches in a front-yard setback), and walls over six feet must be engineered. Fence or wall heights above the Zoning Code limits also require a Site Development Permit or Use Permit.

The Orange County Zoning Code restricts chain-link fencing in required front setbacks but does not, in Section 7-9-64, set a general list of prohibited fence materials such as barbed wire or razor wire. Material and engineering standards instead come from building-permit review for walls and fences over six feet.

Shared boundary fences in unincorporated Orange County are governed by California Civil Code Section 841, the Good Neighbor Fence Law. Adjoining owners are presumed equally responsible for the reasonable cost of a boundary fence, and a 30-day written notice is required before charging a neighbor for the work.

Retaining walls in unincorporated Orange County are regulated as walls under Zoning Code Section 7-9-64. A fence on top of a retaining wall is measured from the base of the wall. Retaining walls holding back more than four feet of earth, or subject to surcharge or slope loads, must be engineered and permitted.

Keeping horses, cattle, sheep, swine, and goats in unincorporated Orange County is regulated by the County Zoning Code's animal-keeping standards. Equine require a minimum parcel of one acre unless the underlying zone says otherwise, and all such livestock must be kept at least 50 feet from neighbors' homes and 20 feet from any property line.

Orange County has no leash law for cats and cat licensing is optional under OCCO 4-1-85. However, cats are still 'animals' under OCCO 4-1-49, so an owner may not let a cat trespass onto another person's private property without consent. Owning four or more cats over four months old requires an Animal Permit under OCCO 4-1-76.

Orange County addresses hoarding through its Animal Permit limits and through California's animal-cruelty law. Owning four or more dogs or cats over four months old requires an Animal Permit (OCCO 4-1-76). Keeping animals in conditions that deprive them of food, water, or shelter is criminal neglect under California Penal Code 597, a wobbler punishable as a misdemeanor or felony.

Orange County charges substantially higher dog license fees for unaltered dogs and requires spay or neuter for impounded animals before release, encouraging sterilization and reducing shelter intake countywide.

Orange County encourages residents to haze coyotes, secure attractants, and report aggressive encounters under a coordinated management plan run with OC Animal Care, OC Parks, and California Department of Fish and Wildlife.

Orange County requires dogs four months and older within OC Animal Care jurisdiction to be microchipped before or at the time of license issuance, ensuring lost pets can be returned quickly to owners.

Under OCCO 4-1-76, anyone in unincorporated Orange County who keeps four or more dogs or four or more cats over four months of age must obtain an annual Animal Permit from OC Animal Care. Up to three dogs and three cats may be kept without it. All dogs four months and older must be licensed (OCCO 4-1-70).

California AB 485 prohibits pet stores in Orange County from selling dogs, cats, or rabbits unless sourced from animal shelters or approved rescue organizations, and OC Animal Care inspects compliance under the state mandate.

Orange County zones veterinary hospitals into commercial and limited industrial districts and requires conditional use permits when overnight boarding, outdoor runs, or large-animal services are part of the operation.

Beekeeping in unincorporated Orange County is governed mainly by California state law: under Food & Agricultural Code 29040, every beekeeper must register their apiary's location and colony count with the County Agricultural Commissioner by January 1 each year, or within 30 days of acquiring bees. Hive placement is also subject to the County Zoning Code's setback standards.

Orange County does not ban any dog breed. California Food & Agricultural Code 31683 prohibits cities and counties from adopting breed-specific dog laws, except for spay/neuter or breeding programs. Instead, OC Animal Care regulates individual dogs through the 'potentially dangerous' and 'vicious' dog process under OCCO 4-1-23 and 4-1-95, based on behavior rather than breed.

Keeping chickens and other fowl in unincorporated Orange County is governed by the County Zoning Code's animal-keeping standards (section 7-9-105, Pets and animals). Poultry and birds are limited by lot area, roosters and peacocks are generally not allowed in residential zones, and birds must be kept set back from neighboring dwellings and property lines.

Orange County's Title 4 animal ordinances do not set a general countywide ban on feeding wildlife, so the controlling rules come from California state law. Title 14 CCR 251.3 prohibits knowingly feeding big game mammals (deer, elk, antelope, bear, bighorn sheep), and 14 CCR 251.1 bars harassment that disrupts wildlife. Feeding that attracts predators can also create a public-nuisance problem.

In unincorporated Orange County, OC Animal Care enforces Codified Ordinance 4-1-45: any dog on public property must be restrained by a substantial chain or leash not exceeding six feet, under the charge of a competent person. Dogs are also barred from public school property, certain county parks, and public beaches under 4-1-46 (guide and service dogs excepted).

Under OCCO 4-1-94, no one in unincorporated Orange County may keep any wild, exotic, dangerous, or non-domestic animal without first receiving a license from OC Animal Care, and the animal must conform to County zoning. California state law adds a separate ban on many species — for example, ferrets are illegal to own statewide.

In unincorporated Orange County, OC Public Works requires a building permit before constructing a swimming pool or spa. Applicants submit a Building Permit Application, a Pool/Spa Questionnaire, and stamped plans through myOCeServices. Planning approval and plan check are required prior to issuance.

Under County Ordinance 19-006 and the California Swimming Pool Safety Act, new and remodeled pools and spas in unincorporated Orange County must have a secondary drowning-prevention barrier in addition to the perimeter fence, such as a removable mesh fence, safety pool cover, or pool entry alarm.

The California Swimming Pool Safety Act and Orange County's pool rules apply to any structure intended for swimming that holds water more than 18 inches deep. Above-ground pools meeting that depth need a building permit and must satisfy the same enclosure and drowning-prevention requirements.

Spas and hot tubs are treated like pools in unincorporated Orange County. The OC note sheet's enclosure and secondary-barrier rules apply, and under the California Pool Safety Act a spa holding more than 18 inches of water needs a building permit and at least two drowning-prevention features.

Pools and spas in unincorporated Orange County must be completely enclosed by fencing at least 5 feet high with no openings greater than 4 inches. Gates must be self-closing and self-latching, swing outward, and have the latch a minimum of 5 feet high.

Section 7-9-104 of the Orange County Comprehensive Zoning Code allows home occupations only as an accessory use to a residence, conducted entirely within the enclosed living area, with no exterior evidence, no signs, no more than one client at a time, and no change to the dwelling's residential character.

Orange County prohibits signs for home occupations. Under Section 7-9-104(c)(8) of the County Comprehensive Zoning Code, there shall be no signs, and there must be no exterior evidence that a home occupation is being conducted at the residence.

Orange County's Zoning Code (Sec. 7-9-104) permits home occupations as an accessory use without listing a separate zoning permit, provided the standards are met. OC Planning issues use/occupancy permits when a property's use changes, and business licenses for unincorporated areas are handled by the Sheriff's Department.

Cottage food operations in unincorporated Orange County register with the OC Health Care Agency under the California Homemade Food Act. Class A (direct sales, $75,000 annual limit) requires registration with no inspection; Class B (wholesale, $150,000 limit) requires a permit with a yearly inspection.

Both small (up to 8 children) and large (up to 14 children) in-home family child care are permitted by right in residential and agricultural zones under Section 7-9-95.5 of the Orange County Zoning Code, consistent with California SB 234 (HSC 1597.45/1597.46). No County use permit is required; a use permit applies only to centers serving more than 14.

In unincorporated Orange County, Zoning Code Sec. 7-9-90 allows one ADU plus one JADU on single-family lots through a ministerial permit, consistent with California ADU law. Detached or attached ADUs may reach 1,200 sq ft; JADUs up to 500 sq ft.

Unincorporated Orange County Zoning Code Sec. 7-9-116 exempts one small detached non-habitable structure under 120 sq ft and 8 feet tall per 7,200 sq ft of lot from setback/coverage rules, if kept 3 feet from rear/side lines and 6 feet from other buildings.

In unincorporated Orange County, an existing garage or carport may be converted to an ADU under Zoning Code Sec. 7-9-90, and no replacement parking is required when a garage is converted to or removed for an ADU, consistent with California state law.

A carport in unincorporated Orange County is an accessory structure under Zoning Code Sec. 7-9-116. Unenclosed carports may cover up to 50% of a side or rear required setback area, and an existing carport may be removed for an ADU without replacing parking.

Unincorporated Orange County has no dedicated movable-tiny-home ordinance. A permanent, foundation-built tiny home can qualify as an ADU under Zoning Code Sec. 7-9-90 (up to 1,200 sq ft). Tiny homes on wheels are generally treated as RVs under California HCD rules.

Orange County manages coastal shoreline through OC Public Works and the California Coastal Commission. Unincorporated coastal areas require Coastal Development Permits for construction near the shoreline. Beach nourishment and erosion control projects are managed at the county level.

Orange County adopted a Climate Action Plan committing to reduce greenhouse gas emissions across county facilities, fleet, and unincorporated land use, aligning with California statewide carbon-neutrality targets by 2045.

California Air Resources Board regulations limit diesel-fueled commercial vehicle idling to five minutes statewide, applying countywide in Orange County including ports, distribution centers, and school drop-off zones.

California Assembly Bill 1346 phases out the sale of new gas-powered leaf blowers and small off-road engines, applying countywide in Orange County including all 34 cities and unincorporated areas.

Orange County participates in the National Flood Insurance Program and enforces floodplain construction standards in mapped Special Flood Hazard Areas across unincorporated communities and county-administered watersheds.

California Title 24 Part 6 energy standards require cool roof reflectivity for most new and replacement low-slope roofs in Orange County's climate zones 6, 8, and 10, covering all cities and unincorporated areas.

Development within the coastal zone of unincorporated Orange County requires a Coastal Development Permit (CDP) under OCCO §7-9-127 and the California Coastal Act. The County has certified Local Coastal Programs for the Newport Coast, Emerald Bay, and Aliso Viejo segments, with the California Coastal Commission retaining jurisdiction over uncertified segments.

Orange County requires Erosion and Sediment Control Plans (ESCPs) for all grading and building projects in unincorporated areas. The OC Grading and Excavation Code (OCCO Title 7, Division 1, Article 8) and the NPDES MS4 permit mandate erosion prevention BMPs during construction to protect waterways and coastal resources.

Orange County enforces stormwater quality under two Phase I NPDES MS4 Permits issued by the Santa Ana and San Diego Regional Water Quality Control Boards. Title 9 of the OCCO (Water Quality) and the NPDES program require all construction and development projects in unincorporated areas to implement Best Management Practices (BMPs) and submit a Water Quality Management Plan (WQMP) before grading or building permits are issued.

The Orange County Grading and Excavation Code (OCCO Title 7, Division 1, Article 8) requires grading permits for all excavation and earthwork in unincorporated areas. Section 7-1-805 prohibits grading, clearing, brushing, or grubbing without a permit from the Building Official. Drainage facilities must conform to Subarticle 11 of the OC Grading Manual.

California does not mandate seismic gas shutoff valves for existing single-family homes. Some Orange County cities require them upon property sale. SoCalGas recommends but does not require automatic shutoff valves. Installation requires a plumbing permit.

Unincorporated Orange County does not mandate foundation bolting for existing homes. California's Earthquake Brace + Bolt (EBB) program offers grants up to $3,000 for qualifying homeowners to bolt their homes to foundations and brace cripple walls.

Unincorporated Orange County does not have a mandatory unreinforced masonry (URM) retrofit ordinance. California SB 547 required inventories of URM buildings but did not mandate retrofits. Few URM buildings exist in unincorporated OC areas due to newer construction patterns.

Orange County has not adopted a mandatory soft-story retrofit ordinance comparable to Los Angeles (Ordinance 183893) or Santa Monica (Ord. 2479CCS). Multi-family wood-frame buildings with tuck-under parking in unincorporated Orange County are governed only by the seismic provisions in the California Existing Building Code (CEBC) Chapter A4 'Earthquake Hazard Reduction for Existing Wood-Frame Residential Buildings' as adopted by the County of Orange Building Code (Codified Ordinances Title 7, Div. 1).

HOA architectural review in Orange County communities is governed by individual CC&Rs and the Davis-Stirling Act. Most large unincorporated communities require prior approval for exterior modifications. California law limits HOA authority over solar panels, drought-tolerant landscaping, EV chargers, and political signs.

HOA assessments in Orange County are governed by the Davis-Stirling Act. Regular assessments can increase up to 20% per year without member vote. Special assessments exceeding 5% of the annual budget require member approval. Delinquent assessments can result in liens and foreclosure.

CC&R enforcement in Orange County HOAs follows the Davis-Stirling Act. Violation notices must be specific and provide a hearing opportunity. Fines must follow a schedule in the operating rules. HOAs can place liens for unpaid fines but face limits on fine amounts and foreclosure authority.

HOA board procedures in Orange County are governed by the California Davis-Stirling Common Interest Development Act (Civil Code 4000-6150). Board meetings must be open to members with advance notice. Elections must follow secret ballot procedures. Annual budgets and financial reports are mandatory.

HOA disputes in Orange County follow the Davis-Stirling Act's dispute resolution framework. Internal Dispute Resolution (IDR) is the first step. Alternative Dispute Resolution (ADR) must be offered before litigation. The prevailing party in HOA lawsuits may recover attorney fees.

At single-family homes in unincorporated Orange County, propane and charcoal grills are generally allowed with common-sense fire safety. At apartments, condos, and townhomes, the California Fire Code bans charcoal and gas grills on combustible balconies or within 10 feet of combustible construction, unless the building is sprinklered. OCFA enforces these rules.

Outdoor smokers in unincorporated Orange County are treated as cooking devices under the California Fire Code (enforced by OCFA), not as recreational fires. At single-family homes they are generally allowed; at apartments/condos/townhomes, charcoal and other open-flame smokers are banned on combustible balconies or within 10 feet of combustible construction unless the building is sprinklered.

Orange County declares weeds on any parkway, sidewalk, or private property a public nuisance (Codified Ord. Sec. 3-13-3(d)). 'Weeds' means noxious plant material or dry grass, brush, or flammable material creating a fire hazard (Sec. 3-13-2). Annual abatement runs under California Health & Safety Code Sec. 14875-14922; keep dry vegetation 100-200 ft from structures, 10 ft from roads.

Orange County Codified Ordinance Sec. 3-13-9 requires vacant real property in unincorporated areas to be secured and maintained: all landscaped, dirt, concrete, or paved areas and the adjoining parkway must be kept clear of rubbish, litter, and weeds, and graffiti removed. 'Vacant real property' means a parcel left vacant and unoccupied more than 30 calendar days (Sec. 3-13-2).

Orange County, California does not experience snowfall in its unincorporated communities and has no snow removal or sidewalk snow-clearing ordinance. Coastal and inland Southern California climate means this regulation is not applicable. Standard sidewalk maintenance falls under general property maintenance provisions.

In unincorporated Orange County, property that is not maintained to the standards in County Codified Ordinance Title 3, Division 13 (Property Maintenance) and is detrimental to public health, safety, or welfare is a declared public nuisance (Sec. 3-13-3) under Civil Code 3479-3503. Blight includes peeling paint, broken windows, dilapidated walls/fences, graffiti, and deteriorated structures (Sec. 3-13-7).
