Pools must be enclosed by a 60-inch (5-foot) fence with self-closing, self-latching gates, and new construction must provide at least two drowning-prevention safety features from the statutory list.

Riverside County requires a building permit for fences over 6 feet and for retaining walls over 3 feet above lower grade, per California Building Code and Ordinance 457. Fences on property lines between neighbors generally do not need a permit at 6 feet or under, but permits are still needed if engineered footings, masonry, or pool-barrier compliance is involved.

Most fence materials are allowed in unincorporated Riverside County but barbed wire, razor wire, and electric fences are restricted to agricultural zones under Ordinance 348. In WUI fire zones, Ord. 787 and CBC Chapter 7A encourage non-combustible materials next to structures. Scenic corridors prohibit reflective and industrial fence types.

Riverside County Ordinance 348 and Ord. 457 set general fence requirements: front setback limits, sight-distance triangles, pool-barrier standards, and grading rules. In WUI fire areas the Ord. 787 defensible-space rules affect fence materials next to wildland. Agricultural, scenic-corridor, and HOA parcels carry additional layered requirements.

Retaining walls over 3 feet measured from the bottom of the footing to the top of the wall require a building permit in Riverside County under California Building Code §105.2 (as adopted by Ordinance 460). Walls supporting a surcharge (such as a driveway or pool) require a permit at any height. Walls are drawn to seismic standards for Design Category D.

Under Riverside County Ordinance 348 Section 19.2, fences in residential zones are limited to 3.5 feet in the front-yard setback and 6 feet in side and rear yards. Fences over these heights, and all fences in agricultural zones over 6 feet, typically require a building permit and zoning review. Corner-lot sight-distance triangles limit fence height near driveways and intersections.

Wine Country, Aguanga, Anza, and the Banning Pass are notable horse regions.

Under Riverside County Ordinance 348, chickens and small livestock are allowed on most residential-agricultural (R-A), rural residential (R-R), and agricultural (A-1, A-2) parcels. On standard residential (R-1) parcels, small numbers of hens may be kept subject to setback and coop standards. Roosters and larger flocks generally require parcels of 1 acre or more.

Unincorporated Riverside County does not impose breed-specific legislation. California Food & Agricultural Code §31683 bars any local law that declares a dog dangerous based solely on breed. Riverside County Ordinance 630 regulates potentially dangerous and vicious dogs by behavior, not breed. Mandatory spay/neuter can apply only to individual dogs declared dangerous.

Riverside County Ordinance 630 and California Fish & Game Code §251.3 prohibit intentionally feeding big-game mammals (bears, deer, coyotes, mountain lions). Feeding wildlife creates dangerous habituation and triggers public-safety responses. Bird feeders are generally allowed but can be cited if they attract rodents, bears, or create a nuisance.

Beekeeping in unincorporated Riverside County is regulated under Ordinance 348 and California Food & Agricultural Code §29001+. Apiaries must be registered annually with the County Agricultural Commissioner.

California ADU law (Gov Code §65852.2) requires the County to ministerially approve garage conversions to ADUs and waives the replacement-parking requirement.

Riverside County encourages native and drought-tolerant landscaping through the Model Water Efficient Landscape Ordinance (MWELO) adopted via Ordinance 859. New landscapes over 500 sq ft (2,500 sq ft for owner homeowners) must meet climate-appropriate plant lists, efficient irrigation, and soil management. Desert natives have strong protections under state law.

Riverside County Ordinance 695 requires property owners to abate weeds, dry grass, and combustible vegetation that create a fire hazard. Abatement notices typically require grass and weeds to be mowed to 3-4 inches or less by a published deadline each spring (usually May 1). Non-compliance leads to county-contracted abatement with cost liens.

Unincorporated Riverside County is served by multiple water districts — Eastern Municipal, Western Municipal, Coachella Valley Water District, Desert Water Agency, Rancho California, and others. Under California Water Code §10608 (SB X7-7) and the AB 1668/SB 606 framework, all enforce permanent outdoor water efficiency rules. Typical restrictions limit landscape irrigation to 2-3 days per week and prohibit runoff.

Riverside County Ordinance 695 authorizes the Fire Department to declare weeds and dry vegetation a public nuisance and order abatement. Ordinance 725 treats overgrown vegetation that harbors rodents or impairs neighboring properties as a general nuisance. Invasive weeds (yellow star thistle, arundo) are subject to Ag Commissioner quarantine and abatement.

Tree trimming on private property is generally unregulated in unincorporated Riverside County except where trees overhang county road right-of-way, block sight distance, or are within utility easements. Heritage and native oak protections apply in designated hillside areas. Trees within 10 feet of chimneys must be trimmed under Public Resources Code §4291.

Rainwater harvesting is legal in California under the Rainwater Capture Act of 2012 (AB 1750) and encouraged in Riverside County for landscape irrigation. Rooftop collection of up to 5,000 gallons typically does not require a permit. Larger cisterns, pressurized systems, or indoor uses require permits and California Plumbing Code compliance.

Riverside County does not have a blanket heritage-tree ordinance for private property, but oak woodlands and riparian trees in Multi-Species Habitat Conservation Plan (MSHCP) reserves are protected. Tree removal during grading under Ordinance 457 may require biological survey. Desert native plants (Joshua trees, palms) are protected by state law on any project requiring discretionary approval.

Unincorporated Riverside County allows residents to hold occasional garage sales without a permit, generally limited under Ordinance 348 to two or three events per calendar year per residence with each sale lasting up to three consecutive days. Sales must occur on the resident's own property and cannot create parking or traffic hazards.

Riverside County Ordinance 725 declares accumulation of rubbish, junk vehicles, overgrown vegetation, and deteriorated structures a public nuisance.

Unincorporated Riverside County has no ordinance requiring property owners to clear snow from sidewalks. Most of the county is low-desert and inland valley where measurable snow is rare; the few mountain communities such as Idyllwild, Pine Cove, and Anza receive occasional snow but the county imposes no mandatory clearance rule on adjacent property owners.

Unincorporated Riverside County does not operate a general long-term rental registration program. Short-term vacation rentals (under 30 days) in wine-country and mountain areas must register under Ordinance 927, collect Transient Occupancy Tax, and meet operational standards, but conventional long-term rentals require only a standard county business license where applicable.

California AB 1482 requires just cause to terminate any tenancy in a covered unit in Riverside County after the tenant has continuously occupied the unit for 12 months (or 24 months if a new adult tenant joined). The law distinguishes at-fault reasons (no relocation fee) from no-fault reasons (requires one month of rent as relocation assistance).

Unincorporated Riverside County has no local rent-control ordinance. California AB 1482, the Tenant Protection Act of 2019, applies statewide and caps annual rent increases on qualifying units at 5 percent plus regional CPI (capped at 10 percent total) for rental units more than 15 years old that are not single-family homes owned by non-corporate landlords.

California AB 12, effective July 2024, caps residential security deposits at one month of rent for most Riverside County landlords. Small landlords owning two or fewer properties may collect up to two months on unfurnished units.

California Civil Code 1940.2 prohibits Riverside County landlords from using force, threats, fraud, or repeated unreasonable entries to push tenants out. Violations can result in civil penalties up to 2,000 dollars per harassment incident plus actual damages.

Riverside County Ordinance 655 and nuisance code Ordinance 725 jointly prohibit outdoor lighting that shines directly onto neighboring property or into bedroom windows. Any fixture that casts more than 0.5 foot-candles at a residential property line may be cited as both a lighting-code violation and a nuisance.

Riverside County Ordinance 655, the Mount Palomar Light Pollution Ordinance, imposes some of the strictest outdoor-lighting rules in California. Within approximately 45 miles of Palomar Observatory (Zones A and B) all new exterior lighting must be shielded, low-pressure or filtered low-color-temperature sodium, and most decorative lighting must be extinguished after 11 p.m.

Riverside County Ord. 655 protects Mt. Palomar Observatory through one of the strongest dark-sky lighting laws in the United States, restricting outdoor lighting type, intensity, and curfews across western Riverside County.

Riverside County Ordinance No. 348 (Zoning Ordinance) establishes minimum setbacks for all structures in unincorporated areas. Typical R-1 single-family zones require 20-foot front yards, 5-foot interior side yards, 10-foot street side yards, and 10-foot rear yards, though setbacks vary by zone classification (R-R rural, R-A residential-agricultural, etc.).

Riverside County Ordinance No. 348 limits the percentage of a lot that structures can cover. Typical residential coverage maximums range from 35% in R-1 zones to 50% in R-3 multi-family zones. Coverage is calculated from the footprints of all buildings, including accessory structures, but excludes paved surfaces and pools.

Under Ordinance No. 348, most residential zones in unincorporated Riverside County cap principal structures at 35 feet or 2.5 stories. Accessory structures are generally limited to 18 feet.
