Yorba Linda — Development Standards

Last reviewed: July 3, 2026

Overview

This page summarizes the Yorba Linda Zoning Code rules that control development standards (setbacks, heights, lot coverage, density, and related dimensional rules) so you can check what the Code actually requires for a parcel. Where the Code lists a numeric standard I cite the controlling § and the ordinance excerpt returned by the file search. For rules about parking, design review, overlays, accessory units, and the state building code I link to the relevant guidance pages and the California Building Standards Code as they are referenced by the Zoning Code text.

• For the citywide height cap see § 18.01.050.
• For the residential development table and per-zone numbers see Table 18.10-2 (property development standards) in § 18.10.090.
• For accessory dwelling unit standards see § 18.20.850.

Note: This page covers only development/dimensional standards in the Yorba Linda Zoning Code — not building code (Title 24) work or state housing law procedures. For building code technical compliance see the California Building Standards Code. For related local topics see the city's pages on parking, design review, overlay districts, and ADUs.

District-by-district development standards

Notes on citations below: where I summarize numeric standards I cite the table or section that contains those numbers. The primary tables are Table 18.10-2 for residential zones and Table 18.12-2 for commercial; special-purpose zones have their own subsections. See Source References at the end for full pointers.

R-A (Residential — Agricultural)

• Purpose & uses: Large-lot residential/agricultural uses; typical permitted uses are single-family and agricultural uses (see residential uses table and § 18.10.080).
• Key standards (from Table 18.10-2): Maximum density 1.0 unit/acre, minimum lot size 1 acre, minimum front yard 40 ft, maximum lot coverage 35%. See § 18.10.090 (Table 18.10-2).

RLD (Residential Low Density)

• Purpose & uses: Low-density single-family neighborhoods; consult the uses table for permitted accessory and conditional uses. See § 18.10.090 and Table 18.10-2.
• Key standards: Maximum density 1.0 unit/acre, minimum lot size 39,000 sq ft, minimum front yard 35 ft, maximum lot coverage 35% (Table 18.10-2)

• Key standards: Maximum density 4.0 units/acre, minimum lot size 7,500 sq ft, front yard 20 ft, maximum lot coverage 40%.

R-M (Residential Multi‑Family)

• Purpose & uses: Garden apartments, townhouses, clustered housing. See § 18.10.070 describing R‑M.
• Key standards (Table 18.10-2): Maximum density 10 units/acre, minimum lot size 15,000 sq ft, maximum lot coverage 45%, building height up to 40 ft or 3 stories (whichever is less), front yard 20 ft, minimum rear 20 ft. See § 18.10.090 (Table 18.10-2).

R-M-20 (Residential Multi‑Family 20)

• Purpose & uses: Multi‑family up to 20 du/acre. See § 18.10.071.
• Key standards (Table 18.10‑2): Maximum density 20 units/acre, minimum lot size 1 acre, maximum lot coverage 65%, building height up to 50 ft / 4 stories (whichever is less), front yard 20 ft.

R-M-30 (Residential Multi‑Family 30)

• Purpose & uses: High-density multi‑family up to 30 du/acre; see § 18.10.072.
• Key standards: Maximum density 30 units/acre, minimum lot size 1 acre, maximum lot coverage 70%, building height up to 50 ft / 4 stories, front yard 20 ft (Table 18.10‑2).

C-O, C-N, C-G (Commercial — Office / Neighborhood / General)

• Purpose & uses: Office, neighborhood commercial, and general commercial uses. Consult the commercial uses tables and § 18.12.070 for special requirements.
• Key standards (Table 18.12-2):
  • C-O: minimum lot width 100 ft, minimum front setback 25 ft, lot coverage 60%.
  • C-N: minimum lot width 100 ft, front setback 25 ft, lot coverage 35%, max height 35 ft.
  • C-G: minimum lot width 300 ft, front setback 25 ft, lot coverage 50%, max height 35 ft.
    Additional special requirement: where a C zone abuts an R zone, require 50 ft setback to the residential lot line (§ 18.12.070.A).

PL (Presidential Library) — special-purpose zone

• Purpose & uses: Special-purpose standards for the Presidential Library site. See § 18.16.320.
• Key standards (§ 18.16.320): street-facing setback 50 ft, interior setback 5 ft, maximum building height 35 ft / 2 stories, maximum building coverage 35%.

MHP (Mobile Home Park)

• Purpose & uses: Mobile home park standards. See § 18.16.020 and Table 18.16-1.
• Key standards (Table 18.16-1): minimum site area 20 acres, setback adjoining a street 20 ft, interior lot line setback 15 ft, maximum height 35 ft.

OS / OSR (Open Space and Open Space Ranchettes)

• Purpose & uses: Preserve natural resources / low-intensity private use; development is limited and subject to Open Space rules. See Art. 5 (Open Space zones) and § 18.16.400 et seq.

PD (Planned Development)

• Purpose & uses: Allows a tailored mix of uses and custom standards through a development plan; the PD ordinance itself adopts the specific development standards for the PD parcel. See §§ 18.16.130–18.16.160 for procedures and required plan elements.
• Key point: PDs set their own setbacks, heights, densities and lot coverage in the adopted PD development plan (must be adopted by ordinance).

Senior Citizen Housing (special development standards)

• Where a project meets eligibility rules, special senior housing standards apply. Table 18.18-1 establishes minimum front setback 20 ft, side 10 ft interior / 20 ft street, maximum height 35 ft, maximum density 25 units/net acre, and maximum site coverage 60% (§ 18.18.060, Table 18.18-1).

Key citywide rules, exceptions and procedures

• Citywide maximum height cap: 35 ft measured from lowest exterior ground point to highest structure point unless exempted; see § 18.01.050.
• Table-driven zone standards: For residential zones the controlling numeric table is Table 18.10-2 (referenced in § 18.10.090). For commercial zones the controlling numeric table is Table 18.12-2 (see § 18.12.070).
• Minor deviations: the Community Development Director may grant minor deviations up to 10% for development standards except density, FAR, or parking (§ 18.02.100).
• Administrative adjustments / exceptions: broader adjustments (beyond minor deviations) go through the administrative adjustment or variance procedures administered by the Zoning Administrator or Planning Commission (see Chapter 18.38).
• Density bonuses, concessions, and waivers: The Code contains density bonus rules and lists concessions/incentives (e.g., reduced setbacks, increased height or coverage) available for qualifying affordable projects — see Chapter 18.19 (density bonus and concessions) and the findings required for a waiver (§ 18.19.040–080).

Decision‑relevant quick table

Checklist

• Confirm the zoning designation for the parcel in the official zoning map and Land Use Element. See Yorba Linda Zoning and Yorba Linda Land Use.
• Use Table 18.10-2 or Table 18.12-2 as your numeric baseline (residential or commercial) and record applicable density, lot coverage, setbacks, and height (§ 18.10.090, § 18.12.070).
• Check overlay districts or site-specific PD standards (see overlay districts); overlays can change allowable density/height.
• For ADUs, verify the special ADU rules (minimum 4‑ft side/rear setback exceptions, ADU height caps) in § 18.20.850 and the ADU page Yorba Linda ADUs.
• Calculate parking demand against Chapter 18.22 and the local parking guidance; confirm whether any parking reductions apply (density bonus or transit proximity).
• See if a project will trigger design review or conditional use permit requirements and include the required materials early.
• If you seek minor deviations or administrative adjustments, document the specific standard and whether the deviation falls within 10% minor deviation authority (§ 18.02.100) or requires the administrative/variance path (Chapter 18.38).

Risks & Ambiguities

Plain‑English Summary

Yorba Linda's Zoning Code sets dimensions by zone using tables: the residential Table 18.10‑2 gives maximum density, front/side/rear setbacks, lot coverage and typical height limits (e.g., many zones allow up to 35 ft or more in multi‑family zones), commercial zones use Table 18.12‑2, and special zones (PL, PD, MHP, senior projects) have their own numeric tables — check the table relevant to your zone, confirm overlays/PDs, and use the ADU rules for accessory units. (See § 18.10.090, § 18.12.070, § 18.20.850, § 18.16.320.)
