Before You Build in Pico Rivera, CA: Permit & Rule Checklist (2026)

Pico Rivera requires a permit for fencing and block walls to confirm compliance with the Zoning Code's height and setback rules. The city provides a Blockwall/Fence/Pilaster permit application, submitted through the Community and Economic Development Department, with plan review by the Planning and Building Divisions.

Pico Rivera distinguishes non-solid (open) fencing from solid fences, walls, and solid hedges, allowing more height for open styles in the front-yard setback. New subdivisions commonly require a 6-foot masonry perimeter wall using earth-tone slumpstone with stucco and river-rock accents along street frontages.

Pico Rivera's Zoning Code sets shared height limits (6 feet behind the front-yard setback), but responsibility for a division fence between neighbors is governed primarily by California Civil Code Section 841, which presumes adjoining owners share equally in the reasonable cost of a boundary fence.

Under Pico Rivera Municipal Code 18.42.050 (Note 32), a non-solid fence may not exceed 4.5 feet in a required front-yard setback, and a solid fence, wall, or hedge may not exceed 3.5 feet. Behind the front-yard setback, a fence, hedge, or wall may reach 6 feet anywhere on the lot.

Retaining walls in Pico Rivera require building-permit review under the Title 15 building regulations, and any fence placed on top of a retaining wall must still satisfy the Zoning Code fence-height limits in Section 18.42.050 measured from the finished grade of the subject property.

Every new or remodeled pool in Pico Rivera must be enclosed by a barrier at least 60 inches high, with a maximum 2-inch ground gap and openings too small to pass a 4-inch sphere, and self-closing, self-latching gates, under the California Swimming Pool Safety Act.

Above-ground pools, spas, and hot tubs over 18 inches deep are private pools in Pico Rivera and require a building permit plus a compliant 60-inch barrier. The pool wall may serve as the barrier only if it meets the height and non-climbable standards of the California Pool Safety Act.

New and remodeled pools in Pico Rivera must include at least two of the seven drowning-prevention safety features in the California Swimming Pool Safety Act, plus the required barrier and anti-entrapment drain covers, verified at final inspection by the city Building Division.

Hot tubs and spas over 18 inches deep are private pools under Pico Rivera Municipal Code Title 15 and need a building permit, electrical bonding, and a barrier. A spa is exempt from the barrier if it has an approved ASTM-listed safety cover under the California Pool Safety Act.

Pico Rivera requires a building permit before installing any private swimming pool, spa, or hot tub over 18 inches deep, issued by the city Building Division under Municipal Code Title 15, which adopts the California Building and Residential Codes.

Pico Rivera approves ADUs ministerially under state law (Gov. Code 66310-66342). Detached units run 800 to 1,000 square feet, attached ADUs up to 50% of the primary home, with a 4-foot side and rear setback and no owner-occupancy requirement for standard ADUs.

Pico Rivera allows converting an existing garage or accessory structure into an ADU. Setback and separation standards are waived for a legal existing structure, but the conversion still needs a permit and must meet fire and life-safety requirements.

Pico Rivera has no separate tiny-home ordinance; a permanent tiny house on a foundation is regulated as an ADU, which allows units as small as a 150-square-foot efficiency unit. Tiny homes on wheels are not recognized as permanent dwellings.

Carports and patio covers are accessory structures in Pico Rivera reviewed by Building & Safety. They must meet yard setbacks and building-separation standards and generally require a building permit before construction.

Detached storage sheds and similar accessory structures are permitted in Pico Rivera residential yards but must observe building separation and setback standards, and larger sheds require a building permit through the Community and Economic Development Department.

Open outdoor burning in Pico Rivera is tightly restricted. The city adopted the Los Angeles County Fire Code as Municipal Code Chapter 15.44, so open burning needs a Fire Department permit. South Coast AQMD burn-day rules effectively prohibit routine yard-waste and trash burning in this urban city.

Outdoor fire pits and recreational fires in Pico Rivera follow the Los Angeles County Fire Code, adopted as Municipal Code Chapter 15.44 and enforced by the LA County Fire Department. Small recreational fires and approved portable fireplaces are allowed but must be attended and kept clear of structures.

Pico Rivera has no general private-property tree-preservation ordinance. Trees fully on private land can usually be removed without a city permit. But removing a roadside or parkway tree in the public right-of-way requires a Public Works permit under PRMC Chapter 12.40, and parkway trees are city-protected.

Trimming your own trees on private property needs no city permit in Pico Rivera. But roadside and parkway trees in the public right-of-way are protected: a Public Works permit is required to trim them, and cutting parkway trees is prohibited (PRMC Chapters 12.40, 12.48).

The city-run Pico Rivera Water Authority declared a Stage 2 shortage with mandatory limits: a one-day winter schedule Nov 1-Mar 31 (even addresses Tuesday, odd addresses Thursday, ~5 minutes per station) and no weekend irrigation. Pico Water District and San Gabriel Valley Water Company customers follow separate rules.
