Pico Rivera Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

Pico Rivera's zoning and land‑use rules are codified in Title 18, The Comprehensive Zoning Code of the Pico Rivera Municipal Code § 18.02.010 . The code organizes definitions, zone chapters, property‑development tables and procedural chapters so that the official zone map and district rules live in Chapters 18.10–18.38 with citywide standards and procedures elsewhere in Title 18 § 18.08.080 . Specific plans (e.g., SP‑301, SP‑400, and the recently adopted SP‑Mercury) and overlay districts sit alongside base zones and change how the base standards apply on targeted sites § 18.19.010 ; § 18.21.010 . This page orients you to where the real rules are, how the city handles permit review, and how state housing laws are implemented locally.

How Pico Rivera's code is organized

• Title & purpose: The zoning code is explicitly titled Title 18 and sets the legal authority, intent and administration for zoning in Pico Rivera § 18.02.010 .
• Definitions & diagrams: core definitions (building height, setbacks, building coverage, “second dwelling unit”, etc.) are in the definitions chapter (Chapter 18.04), e.g., § 18.04.152 (building height) and § 18.04.148 (building coverage) .
• Zone chapters: the code puts the zone rules into sequential chapters (Chapters 18.10–18.38); the Official Zone Map shows locations and boundaries § 18.08.080 .
• Citywide development rules and tables: minimum yards, open space, allowable building coverage and many objective development standards are in the property development chapter and its adopted charts (Chapter 18.42, including property development chart adoption § 18.42.010–§ 18.42.020 ) .
• Use lists and special‑use notes: permitted uses for base zones are listed in Chapter 18.40; the chart notes and special conditions (including second‑unit rules and streamlined housing site notes) are collected under § 18.40.050 .
• Parking, signs and other technical chapters: off‑street parking standards are implemented in Chapter 18.44 (parking) and signs are in Chapter 18.46; individual zone chapters routinely point to those chapters for parking and signage requirements (for example, the R‑M zone points to Chapter 18.44 for parking § 18.18.060 and to Chapter 18.46 for signs § 18.18.070 ) .
• Procedures & discretionary review: precise plans of design, conditional use permits, design review appeals and enforcement are handled in Chapters 18.48, 18.56 and 18.64 (see § 18.48.010, § 18.48.020, and § 18.48.095 for the precise plan procedures and permit timing) .

Quick navigation pointers: start with the definitions in Chapter 18.04 to confirm terms like “yard,” “second dwelling unit” or “precise plan of design” (§ 18.04.908, § 18.04.320, § 18.04.660) and then open the base zone chapter (e.g., R‑M at § 18.18.010) for zone‑specific cross‑references to Chapters 18.40, 18.42, 18.44 and 18.46 that contain the actual technical requirements .

Zoning district families

Pico Rivera uses a set of base zone families (single‑family, multiple‑family, commercial and industrial) plus overlays and specific plan zones. Key, Pico‑Rivera‑specific names you will see in the code (and where to find them) include:

• R‑E (Single‑Family Residential Estate) and S‑F (Single‑Family) — single family zones and related lot‑area/density notes are in the R‑zone chapters and Chapter 18.42 (property development) § 18.42.010 .
• R‑M 3000 (Multiple‑Family Residential variable density) — established in § 18.18.010 with intent/criteria in § 18.18.020–§ 18.18.030 and with explicit referrals to the permitted‑use chapter and property‑development chapter § 18.18.040–§ 18.18.050 .
• Commercial groupings — C‑N (Neighborhood Commercial), C‑C (Community Commercial), C‑G (General Commercial), C‑M (Commercial Manufacturing), and planned commercial forms like CPD — each commercial chapter points to the general use and development chapters (see, e.g., § 18.32.030–§ 18.32.050 for C‑M) .
• Industrial groups — I‑L (Limited Industrial), I‑G (General Industrial) with special conditions in each industrial chapter § 18.32.050 references and other notes .
• Public, parking & open space zones — P (Parking), O‑S (Open Space), Public Facilities (PF) appear as their own chapters such as § 18.20.010 for Public Facilities .
• Overlay and plan districts — major overlays and site‑level plans include the M‑U Mixed‑Use overlay (§ 18.33.010–§ 18.33.030) and specific plans like SP‑301, SP‑400, and SP‑Mercury each enacted as their own chapter with detailed tables and administered by master conditional permits where required § 18.33.010 .
  These district names are also reflected in the code’s zone reclassification / additions language for the Official Zone Map § 18.66.040 .

Citywide development standards (high level)

• Where the rules live: objective property development tables, yard/setback parameters, lot‑coverage and many uniform standards are adopted in Chapter 18.42 (Property Development Regulations) and the Chapter incorporates a “property development chart” § 18.42.010–§ 18.42.020 .
• Setbacks & projections: the code defines a building setback and yards in the definitions (§ 18.04.172, § 18.04.908) and applies interior/front/rear setback rules via the property development charts and the zone‑specific notes (see Note 60/61 in the mixed‑use/multifamily design notes) § 18.04.172 .
• Height & building coverage: the code’s measurement rules are in the definitions (for example, building height is defined at § 18.04.152 and building coverage at § 18.04.148) and zone chapters and specific plans set zone‑ or site‑specific maxima (e.g., SP‑Mercury limits building height to seventy feet in its site standards § 18.21.040) .
• Floor Area Ratio (FAR): mixed‑use standards and some specific plan notes specify FAR caps (mixed‑use non‑residential component maximum intensity of 1.0 FAR, Note 59) and the property development chapter ties the charts to the zone rules § 18.42.020; see also mixed‑use notes on FAR § 18.42.020 .
• Parking: off‑street parking requirements are handled in Chapter 18.44; individual zones refer developers to Chapter 18.44 for the parking table and for compact/assignable parking rules (e.g., § 18.18.060 and the parking notes adopt the Parking Standards Diagram in § 18.44.050 ) .
• Design standards and public image: objective design standards for multifamily/mixed‑use projects (including ground‑floor transparency and entry requirements) are incorporated as notes and as objective design rules used in ministerial reviews § 18.33.020 and the objective standards note (Note 64) apply to state‑law ministerial projects .

(For a focused read on the technical parking rules start at the city's parking chapter; for site design and objective standards consult the development‑standards and design‑review chapters.)

Specific plans & overlays

• Mixed‑Use Overlay (M‑U Overlay): enables integrated residential + commercial development close to one another and is explicitly intended to implement housing opportunity sites and the Housing Element § 18.33.010–§ 18.33.030 . The overlay lets the overlay rules prevail in some respects over the underlying base zone standards for eligible mixed‑use projects § 18.33.030 .
• Specific Plan 400 (SP‑400): a large, multi‑scenario redevelopment plan with its own land‑use/density tables (Table C) and mandatory master conditional use permit requirements before redevelopment § 18.19.010–§ 18.19.060 . SP‑400 contains four alternative development scenarios (manufacturing retention, mega‑mall, theme‑park, mixed‑use) each with distinct build‑out and design directions § 18.19.030 .
• Specific Plan Mercury (SP‑Mercury): a recent small‑area specific plan that prescribes a 255‑unit mixed‑use project on a 2.8‑acre site and includes explicit height and setback tables (building height cap 70 ft) § 18.21.010–§ 18.21.040 .
• Additions and map updates to the Official Zone Map are controlled through the zone‑reclassification and amendment procedures in § 18.66.020–§ 18.66.040 and each specific plan chapter directs that development must be consistent with the specific plan tables and urban design plan (e.g., § 18.19.040–§ 18.19.050) .

Building permits & review (the usual pathways)

• Zoning administration & permit sign‑off: the Zoning Administrator and Director of Building & Planning administer the code; the director must approve permits for zoning compliance before final occupancy (see issuance duties) § 18.06.030–§ 18.06.050 .
• Ministerial vs. discretionary: many routine projects are reviewed ministerially through an administrative Zoning Consistency Review (ZCR) or precise plan of design (PPD) process; the PPD is defined in § 18.04.660 and processed per Chapter 18.48 § 18.48.010–§ 18.48.040 . Larger or use‑sensitive projects require discretionary review like a conditional use permit (Chapter 18.56) or master conditional use permit for specific plans § 18.19.010 .
• Precise Plan / Design Review: a precise plan of design is required for many projects above size thresholds and triggers design review and potential appeals to the Design Review Board; the PPD application, findings and permit term/expiration rules appear in § 18.48.020–§ 18.48.095 and the design review board procedures are in § 18.48.100–§ 18.48.130 .
• Time limits & enforcement: permits have expiration and extension rules in § 18.48.095 and code violations carry misdemeanor penalties in enforcement § 18.06.130 .
• How to start: submit to the Zoning Administrator or Building Department (see § 18.06.030 for the zoning administrator's duties) and check whether your site is on a Housing Element “opportunity site” that may qualify for streamlined or ministerial approvals § 18.06.030; § 18.40.050 Note 76 includes streamlined procedural direction for Housing Element sites § 18.40.050 .

State housing law in Pico Rivera

• Accessory / second units (ADUs / SDUs): Pico Rivera’s code defines a “second dwelling unit” (second unit/ADU) and provides a local regulatory framework that treats secondary units as allowed accessory residential units, including ministerial review and objective standards; see the definition § 18.04.320 and the second‑unit rules collected as chart note/condition under § 18.40.050 (Note 75) which specifically invokes Government Code § 65852.2 and sets ministerial, one‑per‑lot, size and parking expectations § 18.04.320 . See also the city’s streamlined site‑plan direction for Housing Element sites § 18.40.050 Note 76 .
  • Practical take: the code establishes a local second‑unit program (with maximum unit size limits, parking, owner‑occupancy covenant and objective findings) — check § 18.04.320 and § 18.40.050 for the controlling local text .
• Density bonus & affordable housing incentives: Pico Rivera has a density‑bonus program and related rules in Chapter 18.42 (including additional density bonus rules § 18.42.160 and the density‑bonus tables) that implement state bonus law and extended affordability requirements § 18.42.150–§ 18.42.160 .
• By‑right / ministerial housing on Housing Element sites: the code includes a streamlined administrative path for projects on identified Housing Element sites and references state streamlined laws (SB‑35 and related Government Code sections) within § 18.40.050 Note 76 and the mixed‑use overlay intent § 18.33.020 .
• SB 9 / lot splits and other state defaults: the Pico Rivera code contains objective development tables and ministerial pathways that will interact with state law; where the city provides objective rules (e.g., Chapter 18.42 charts, ADU rules in § 18.40.050), those are the starting point — but for new statewide program rules (SB 9 / SB 10 variants) confirm current interpretation with the Planning Department (many state‑level mandates require local code updates or administrative interpretation) § 18.02.020 (statutory authority) .

NOTE: For the state building code baseline, Pico Rivera’s permit and construction inspections must comply with the California Building Standards Code (Title 24); local zoning is separate and cross‑checks with building standards at permit issuance § 18.06.050 (issuance of permits and withholding occupancy until zoning compliance) .

Practical orientation — where to look first

1. Is the property on the Official Zone Map? Check the map and Chapter 18.08 (Official Zone Map rules) § 18.08.060–§ 18.08.080 .
2. Read the base zone chapter for your parcel (e.g., § 18.18.010 for R‑M) to see permitted uses and direct references to Chapters 18.40, 18.42, 18.44 and 18.46 for detailed standards § 18.18.040–§ 18.18.060 .
3. If your site is in an overlay or specific plan (M‑U, SP‑400, SP‑Mercury), read the specific plan chapter first — specific plan chapters control and often supersede base zone standards § 18.19.030–§ 18.19.060 .
4. For small residential changes and ADUs consult the second‑unit rules in § 18.04.320 and the special‑use notes (Note 75 / § 18.40.050) before preparing a building permit submittal .
5. For design and discretionary projects start with a precise plan (Chapter 18.48) and the Design Review Board rules § 18.48.020–§ 18.48.100 .
