Yorba Linda — Signage

Last reviewed: July 3, 2026

Overview

This page summarizes the City of Yorba Linda's local sign rules (Title 18, Chapter 18.24) and how they apply by district. It focuses only on what the zoning/planning ordinance requires for signs: allowed sign types, maximum sign area and height, temporary sign rules, review triggers (Planning Commission, planned sign programs), exemptions, and nonconforming-sign elimination timelines. For the zoning context see Yorba Linda Zoning and for related site constraints look at the City's rules for parking and design review. Verify with the jurisdiction for parcel-specific interpretations.

How to read this page

• Bolded items are either ordinance labels (districts) or the controlling numeric standards and code citations (for quick scanning).
• Each technical requirement is grounded to the controlling ordinance paragraph (the § citation is given and supported by the retrieved ordinance file). The file preview supporting that text is also cited inline.

Key district-by-district rules

Note: The controlling sign chapter is Chapter 18.24 — SIGNS in the Yorba Linda Zoning Code (Title 18). Many approvals, deviations or consolidated programs are handled through the Planning Commission or as part of a design-review/conditional-use process; see the city's design-review procedures for how appearance and materials are evaluated. The ordinance also refers applicants to building-standard requirements for structural and electrical safety under the California code; see the state's California Building Standards Code link for those technical requirements.

R zones (all residential categories — e.g., R-A, RLD, R-S, R-U, R-M)

Purpose & typical uses

• Residential-only lots and multi-family complexes.

Permitted signs and key numeric limits

• Single-family: one unlighted nameplate not exceeding 1 sq ft. § 18.24.140
• Multi-family / apartments: one identification sign (lighted or unlighted) up to 12 sq ft; freestanding signs limited to 6 ft height. § 18.24.140

Where it applies

• All parcels in the City's R districts; general R-zone sign limitations are stated in Article 3 of Chapter 18.24. § 18.24.130

Practical note

• Yard/sign placement must avoid sight‑distance and traffic hazards (see temporary and right‑of‑way rules below). For design details that could affect approval, consult Yorba Linda Design Review.

C-O (Commercial — Office) — C-O

Purpose & typical uses

• Professional offices, medical, and office park-type development.

Key sign standards

• One monument (freestanding) sign per project up to 50 sq ft per side, maximum 5 ft height (one additional monument allowed when project has >100 ft frontage or multiple frontages). § 18.24.180
• Wall/canopy signs: 1 sq ft per lineal foot of tenant frontage, capped at 75 sq ft per tenant; directories/nameplates allowed (combined directory up to 15 sq ft when freestanding limited to 6 ft). § 18.24.180

Where it applies

• Parcels zoned C-O (reference City zoning map and the [Yorba Linda Zoning] overview).

C-N (Commercial — Neighborhood) — C-N

Purpose & typical uses

• Smaller retail and neighborhood-serving businesses.

Key sign standards

• Tenant signs: one single-faced, lighted wall or canopy sign at 1 sq ft per lineal foot, maximum 75 sq ft and limited to building frontage actually occupied by the tenant. § 18.24.190
• Shopping center identification: one illuminated freestanding/base sign up to 75 sq ft per side, height up to 8 ft; at least 20% of the face must show the center name/address; individual tenant areas are limited and must be uniform with the center’s sign program. § 18.24.190

Practical note

• Off‑site directional signs for qualifying shopping centers have extra rules (size, distance, Traffic Engineer review). See directional sign rules below and [Yorba Linda Parking] where parking-directional signs are referenced. § 18.24.060

C-G (Commercial — General) — C-G

Purpose & typical uses

• General commercial, larger multi-tenant centers, auto-oriented retail.

Key sign standards

• Freestanding sign: one per lot up to 30 sq ft area (unless multiple businesses on one parcel — combined signage up to 100 sq ft), max 8 ft height. § 18.24.200(A)
• Wall/canopy: 1 sq ft per lineal foot of storefront frontage; up to 100 sq ft per sign; max 2 such signs per use. § 18.24.200(B)
• Shopping center freestanding identification: tenant identification plus center ID combined not to exceed 120 sq ft per side, max 8 ft height. § 18.24.200(C)

Where it applies

• Parcels in C-G; larger mixed-use developments should consider a planned sign program for coordinated identity. § 18.24.380

M-1 (Light Manufacturing) and other industrial/commercial mixed zones

Purpose & typical uses

• Light manufacturing, warehouses, some commercial service uses.

What the code says

• The ordinance does not list a separate, tailored M-1 sign table in the sign chapter. Signs in combining zones or certain overlays follow the base‑zone rules or require Planning Commission approval. For example, signs in (I), (SH), and (H) combining zones “shall be the same as for the base zone, unless otherwise approved by the Planning Commission.” § 18.24.320

Practical note

• Because there is no separate M-1 sign table found in the retrieved materials, verify with the Community Development Director for parcel-specific application. Verify how the industrial lot is classified as a base zone and which Article controls signage. Verify with the jurisdiction.

PS (Public/Semi‑Public) — PS

Purpose & typical uses

• Parks, public facilities, institutional uses.

Key sign standards

• Agricultural uses in PS: one unlighted sign up to 6 sq ft or 6 ft height. Other PS uses: one sign up to 15 sq ft; freestanding signs not to exceed 6 ft height. § 18.24.300

Practical note

• Many public/semi‑public sites will still require Planning Commission review for freestanding signs. § 18.24.350

PL (Presidential Library / Planned area) — PL

Purpose & typical uses

• The PL district is a special planned area (Presidential Library land-use matrix) with its own development standards.

Sign rule

• The PL zone defers sign allowances to Chapter 18.24 and/or requires Planning Commission approval in conjunction with design review or conditional use permits. § 18.16.320(B)

Practical note

• For PL parcels the Planning Commission typically approves signs as part of a larger project permit; expect design-level review. Consult the City's PL standards and design-review procedures for submittal requirements. See [Yorba Linda Design Review].

Combining and overlay districts (e.g., (I), (SH), (H))

How the code treats them

• Signs in (I), (SH), and (H) combining zones are governed by the base zone's sign rules unless modified via Planning Commission action linked to a conditional use permit or design review. § 18.24.320

Where to check

• If the parcel sits in an overlay, consult the overlay standards first ([Yorba Linda Overlay Districts]) and then Chapter 18.24.

Other specialty rules and administrative provisions

• Temporary signs in the public right‑of‑way: allowed only in landscaped parkways (not medians); must be ≤ 6 sq ft and ≤ 4 ft high; cannot obstruct intersections, hydrants or traffic devices; real‑estate directional signs in ROW are sunrise–sundown and all ROW signs must be removed within 5 days of the event. § 18.24.070

• Temporary signs on private property: aggregate per business/residence ≤ 32 sq ft and ≤ 6 ft height unless otherwise stated. Time limits: event signs removed within 5 days; noncommercial temporary signs generally limited to 10 consecutive days unless otherwise specified. § 18.24.070(B)

• Directional (parking) signs: In any zone one parking directional sign ≤ 6 sq ft and/or ≤ 4 ft height at each parking entrance/exit; in commercial/industrial zones the Community Development Director may allow on-site directional signs as part of an overall signage program. § 18.24.060(A)

• Off‑site directional signs for qualifying shopping centers (C zones): special criteria apply (minimum center size, two‑year limit, distance, location on private property adjacent to an arterial, ≤ 8 ft height, 30% of area must identify the shopping center). § 18.24.060(B)

• Church signs: in all zones churches may have one wall sign at 1 sq ft per lineal foot, up to 50 sq ft, plus one freestanding sign up to 50 sq ft and 8 ft high. The Planning Commission reviews freestanding church signs. § 18.24.120

• Exempt signs (no permit required): small open/closed window signs < 2 sq ft, interior non‑visible signs, flags (subject to height limit), official government signs, safety/directional signs meeting Caltrans standards, and other items the Community Development Director identifies. § 18.24.090

• Freestanding sign applications: all freestanding signs (except limited “special purpose” signs) must go through Planning Commission sign-request review; the Commission evaluates size, shape, scale, location, materials, colors and illumination. § 18.24.350

• Planned sign program: shopping centers and commercial complexes with two or more businesses must adopt a planned sign program (gives coordinated design flexibility but must still meet findings). The Planning Commission can approve alternative sign standards through this program. § 18.24.380

• Nonconforming signs: elimination/repair timetable is set by the nonconforming rules — e.g., nonconforming advertising/identification signs in an R zone must be removed within 1 year; in other zones nonconforming advertising signs must be removed within 3 years. See the nonconforming elimination table. § 18.34.040

• Permit fees: sign permit fees are set by City Council resolution and administered by the Building Official; structural/electrical/anchorage requirements remain subject to California building rules (see California Building Standards Code / Title 24). § 18.24.030

Quick reference table — decision‑relevant standards

Checklist (what an applicant must satisfy)

• Confirm the parcel zoning and which Article of Chapter 18.24 controls signs for that district (§ 18.24.170 / Article references) . Link to the City zoning overview: Yorba Linda Zoning.
• Verify sign type limits (area and height) for the district — e.g., C‑G freestanding ≤ 30 sq ft and 8 ft height or combined allowances for shopping centers (§ 18.24.200) .
• If the proposal is a freestanding sign, prepare for Planning Commission review and include design, materials and illumination details (§ 18.24.350) . See Yorba Linda Design Review for aesthetic expectations.
• For shopping centers or developments with ≥ 2 businesses, evaluate the need for a planned sign program and draft uniform tenant standards (§ 18.24.380) .
• For off‑site directional signs or parking-directional proposals, confirm eligibility, obtain City Traffic Engineer review where required, and follow size/location limits (§ 18.24.060) . See Yorba Linda Parking for parking‑sign context.
• Confirm if the sign is exempt (small window signs, flags under size limits, government signs) before paying permit fees (§ 18.24.090) .
• For signs requiring structural/electrical work, coordinate with Building Division on Title 24 / California Building Standards Code compliance and required permits (§ 18.24.030) . Link: California Building Standards Code.
• Check nonconforming-sign removal schedules if altering or changing copy on an existing nonconforming sign (§ 18.34.040) .
• Pay applicable sign permit fees and submit required drawings (area, height, materials, attachment details) per submittal checklist in the Community Development Department (§ 18.24.030) .

Risks & Ambiguities

Plain‑English summary

Most Yorba Linda sign limits live in Chapter 18.24 of the Zoning Code: residential nameplates are very small, multi‑tenant and commercial centers have explicit area/height caps (e.g., C‑G freestanding signs commonly 30 sq ft/8 ft; shopping centers have larger combined allowances but require coordinated programs), temporary signs have strict size/time rules and freestanding signs usually need Planning Commission review. All sign structures that involve electrical or structural work must also meet California building standards (Title 24). § 18.24.140, § 18.24.200, § 18.24.070, § 18.24.350, and § 18.24.380 are the main sections to read.
