Yorba Linda — Zoning

Last reviewed: July 3, 2026

Overview

This page summarizes what the Yorba Linda Zoning Code (local zoning ordinance, Title 18) actually says about zoning districts, the official zoning map, and how the City classifies land and uses. It explains the City’s zone list, how the official zoning map is adopted and maintained, who interprets ambiguous uses, and the residential development standards that the ordinance publishes in Table 18.10‑02. For context and next steps see the Yorba Linda zoning & planning overview and the City’s Development Standards pages.

How the ordinance controls zoning (quick rules)

• The City’s zoning districts and their boundaries are adopted by reference on the official zoning map: § 18.08.030; the original map is kept with the City Clerk and a copy with Community Development: § 18.08.040.
• Which uses are allowed in each zone is determined by the land‑use matrix (Table 18.08‑1) and the abbreviated tables in each chapter; uses not listed are prohibited unless interpreted otherwise by the Director: § 18.08.070, § 18.08.060.
• Residential dimensional/density standards are set in Table 18.10‑02 (see § 18.10.090 and the residential zone chapters). Design and development details are supplemented in zone chapters and PD standards: § 18.10.010, § 18.16.140.

District‑by‑district breakdown

Below are the City’s zone names from the ordinance with the ordinance text or table references that define their purpose and (where the code supplies them) key numeric standards. If a numeric standard is not explicitly in the retrieved material for that district, the entry says so.

Note: the City’s master land‑use matrix is included as an attachment to the Code (Table 18.08‑1); the Community Development Director interprets ambiguous uses: § 18.08.070, § 18.08.060.

R-A (Residential Agricultural)

• Purpose: low‑density agricultural/residential; large lots, agriculture and compatible accessory structures. § 18.10.020.
• Typical permitted uses: single‑family dwellings, agricultural uses compatible with residential character — see Table 18.08‑1. § 18.08.070.
• Key standards: maximum density 1.0 DU/acre, minimum lot size 1 acre (see Table 18.10‑02). § 18.10.090.
• Where it applies: large‑lot parts of the city identified by the official zoning map. § 18.08.030.

RLD (Residential Low‑Density)

• Purpose: low‑density family living; see Chapter 18.10 purpose statement § 18.10.010.
• Key standards: maximum density 1.0 DU/acre, minimum lot size 39,000 sq.ft., minimum lot width 110 ft. (Table 18.10‑02). § 18.10.090.

R-E (Residential Estate)

• Purpose: estate lots at low density (see Chapter 18.10). § 18.10.010.
• Key standards: maximum density 1.8 DU/acre, min lot size 15,000 sq.ft. (Table 18.10‑02). § 18.10.090.

R-S (Residential Suburban)

• Purpose: suburban single‑family areas. § 18.10.010.
• Key standards: max density 3.0 DU/acre, min lot size 10,000 sq.ft. (Table 18.10‑02). § 18.10.090.

R-U (Residential Urban)

• Purpose: higher density single‑family/attached residential consistent with General Plan. § 18.10.010.
• Key standards: max density 4.0 DU/acre, min lot size 7,500 sq.ft. (Table 18.10‑02). § 18.10.090.

R-M (Residential Multiple‑Family)

• Purpose: multi‑family housing district; Chapter 18.10 provides objectives for residential zones generally. § 18.10.010.
• Key standards (general R‑M): maximum density 10.0 DU/acre; see Table 18.10‑02 for lot size and dimensional standards. § 18.10.090.

R‑M‑20, R‑M‑30 (Residential Multiple‑Family 20/30)

• Purpose: higher density multifamily zones with numeric caps. § 18.10.090 (Table 18.10‑02 shows 20.0 and 30.0 DU/acre respectively).

C‑O (Commercial‑Office), C‑N (Commercial‑Neighborhood), C‑G (Commercial‑General)

• Purpose: commercial and office uses; allowed uses and any conditional/design review flags are shown in Table 18.08‑1 (land use matrix). § 18.08.070.
• Where numeric intensity (FAR) appears in the General Plan/Zoning consistency table; see the Code tables/attachments for mapped areas. For exact FARs and dimensional standards, consult the land use matrix and the applicable commercial zone chapter—Table 18.08‑1 is the controlling list of uses. § 18.08.070.

M‑1 (Light Manufacturing)

• Purpose: light industrial/manufacturing uses as defined by the Code list. Uses and performance standards are listed in the land‑use matrix (Table 18.08‑1) and associated zone chapters. § 18.08.070.

MHP (Mobile Home Park)

• Purpose: mobile home park classification is listed among special purpose zones; development standards for MHP are in its chapter (not fully reproduced in the retrieved snippets). § 18.08.020.
• Numeric details: Not found in retrieved materials — verify with the Community Development Department and the MHP chapter. Verify with the jurisdiction.

PD (Planned Development)

• Purpose: flexible, project‑level standards adopted by ordinance as part of a PD zone; PD allows tailored uses and development standards per the approved development plan. § 18.16.140, § 18.16.150.
• Typical requirement: a development plan, maps and text, and the City Council adopts the PD standards into the ordinance creating the PD. § 18.16.140, § 18.16.150.

PS (Public and Semipublic), PL (Presidential Library), OS (Open Space), OSR (Open Space Ranchettes)

• Purpose: special purpose/open space/public uses are explicitly listed as zones; their permitted uses and standards are in dedicated chapters or in the land‑use matrix. § 18.08.020, § 18.08.070.

Combining zones: (O) Oil production, (I) Imperial Highway, (SH) Special Housing, (H) Historic

• These combining overlays modify base zone rules where applied; the list of combining zones is in § 18.08.020. For overlay rules consult the specific overlay chapter or ordinance. § 18.08.020.

Example: Congregational Land Overlay (CLO)

• The ordinance contains a Congregational Land Overlay with its own density range (min 20 DU/acre, max 35 DU/acre), height cap (three stories / 40 ft), off‑street parking rules and adaptive reuse provisions. See § 18.17.230–§ 18.17.270 (Chapter 18.17).

Key development standards (selected, decision‑relevant)

The Code organizes standards in tables. Residential values below are from Table 18.10‑02 (referenced by § 18.10.090). Where table values are used, the ordinance chapter is the controlling reference.

For the master list of allowed/conditional/accessory uses see the land‑use matrix (Table 18.08‑1) described in § 18.08.070; the table is included as an attachment to the Title. § 18.08.070.

Note on height: the Code includes a city‑wide height limit of 35 feet unless exempted (church steeples, public schools, etc.): § 18.01.050.

Off‑street parking standards are referenced in zone chapters and in overlay rules (for example, the Congregational Land Overlay limits residential parking to one space per qualifying affordable unit in conformance with Government Code § 65913.6): see § 18.17.250 and the City parking standards. For on‑site parking requirements consult the City’s Parking standards. (see Yorba Linda Parking)

Practical guidance / interpretation tips

• If your proposed use is not explicitly listed in Table 18.08‑1, the Community Development Director has delegated interpretive authority to decide if the use is similar to a permitted use (and will label it permitted, conditional, or accessory). Appeals of the Director’s decision go to the Planning Commission: § 18.08.060, § 18.08.070.
• For subdivision‑level or complex projects, expect PD or design review requirements; PD projects must submit a development plan and maps and the City Council adopts the PD standards: § 18.16.140, § 18.16.150.
• For residential additions, setback averaging and special residential setback rules exist; see the residential chapter (Table 18.10‑02 and § 18.10.100 special requirements). § 18.10.090, § 18.10.100.

(If your project will check parking, setbacks/development standards, or design review, consult the City’s Parking, Development Standards, and Design Review pages before filing. Links: Yorba Linda Parking, Yorba Linda Development Standards, Yorba Linda Design Review.)

Checklist (what an applicant must satisfy before permit issuance)

• Confirm the property’s zoning and any overlays on the official zoning map (City Clerk / Community Development): § 18.08.030, § 18.08.040.
• Verify that the proposed use is allowed in the zone per Table 18.08‑1 (or obtain Director interpretation): § 18.08.070, § 18.08.060.
• Confirm applicable development standards (density, lot size, setbacks, coverage) — for residential, consult Table 18.10‑02: § 18.10.090.
• Determine parking requirement and compliance (including SB9 or affordable units rules if applicable): see the code and City parking standards and § 18.17.250 for certain overlays.
• Identify triggers for design review, conditional use permit, or variance and prepare required plans: see Table flags in the land‑use matrix and variance rules § 18.36.410 et seq.
• For a PD, file a full development plan per § 18.16.140; for SB9 splits follow Article 14 (SB9) ministerial rules where applicable: § 18.16.140, § 18.20.1000–§ 18.20.1010.

Risks & Ambiguities

Plain‑English Summary

Yorba Linda’s zoning code (Title 18) lists specific zones (R‑A through R‑M‑30, C‑O/C‑N/C‑G, M‑1, PD, PS, PL, OS/OSR and several combining overlays), adopts an official zoning map, and governs what uses and development rules apply where. Use the land‑use matrix and the residential Table 18.10‑02 for the numbers (densities, lot sizes, minimum widths); if a use isn’t listed the Community Development Director interprets whether it’s allowed. Verify parcel‑specific overlays, parking, and any nonconforming claims with the City before committing design or construction. § 18.08.020, § 18.08.030, § 18.10.090, § 18.08.060.
