Concord — Signage

Last reviewed: July 1, 2026

Overview

This page explains how Concord regulates signs under the Concord Development Code (Title 18). It summarizes who needs a sign plan or a master sign program, the by‑district sign area and height rules, common exemptions, and the special-use tables that override district rules. The primary controlling provisions are § 18.180.010 through § 18.180.160 of the Development Code (Chapter 18.180) — see the annotated citations below.

Note: this page covers only the local zoning/planning sign rules in the Concord Development Code. For structural or electrical safety requirements see the California Building Standards Code. (/us/california/building-codes)

What the code controls (high level)

• The sign chapter applies to all signs in all zoning districts and does not regulate message content (commercial or noncommercial). § 18.180.020.
• All signs must meet the chapter’s general standards (materials, illumination, safety) and may also require a building permit, sign plan, or master sign program depending on number/size/type. § 18.180.030, § 18.180.090, § 18.180.050–060.
• The code provides two rulebooks: a district-by-district table (Table 18.180.100) and a use-specific table (Table 18.180.110). Where they conflict, Table 18.180.110 prevails for those uses. § 18.180.100, § 18.180.110.

You should also check related review processes (design and site review) when preparing sign materials — see the Design Review guidance. (/us/california/concord/design-review) and coordinate with parking or loading plans when signage affects curb cuts or visibility (see Parking). (/us/california/concord/parking)

Key local rules and mechanics (code citations)

• Master Sign Program (MSP): larger or coordinated projects may use an MSP to vary the defaults and set consistent standards for all tenants; MSPs must meet the criteria in § 18.180.060 and integrate into leases. Staff can approve limited deviations up to 25%; larger deviations require design review board or planning commission action. § 18.180.060, § 18.180.110.

• Setback for freestanding signs: minimum 5 ft from the public right-of-way unless a specific sign type specifies otherwise. § 18.180.100(B).

• Cumulative area: The "total sign area allowed" counts all permanent signs (attached and freestanding), except where a MSP or Table 18.180.110 allows otherwise. § 18.180.100(C)(1–3), (D).

• Exempt signs (no permit) and limits: The code lists exempt categories and size/time limits (e.g., construction signs in single-family neighborhoods: 12 sf; other districts 40 sf), and other exempt sign rules in § 18.180.070 and general sign requirements in § 18.180.090. § 18.180.070, § 18.180.090.

• Temporary signs: handled by § 18.180.120; the code defines a "temporary sign" as intended for display 30 days or less (definition appears in the code glossary). Verify duration/placement limits in § 18.180.120. Not all temporary‑sign permutations are fully listed in the excerpts here — Verify with the jurisdiction.

• Standards for specific sign types (canopies, menu boards, gas price displays, skyline signs, etc.) are in § 18.180.130 and § 18.180.140 (design). § 18.180.130–140.

• Nonconforming / abandoned signs and enforcement: removal, reinspection fees, and penalties are in § 18.180.150–160. Violations may be a misdemeanor and the city can abate and lien costs. § 18.180.150–160.

District-by-district breakdown (sign standards and where they apply)

Below are the sign rules that Table 18.180.100 assigns by zoning district. This is a synthesis — always confirm with a site‑specific read of the table for multi-tenant or mixed-use exceptions. All district references below are taken from Table 18.180.100 and supporting text in § 18.180.100.

Residential districts — RR, RS, RL

• Typical context/purpose: small‑lot to rural single‑family zones (specific purpose text Not found in retrieved materials). Verify with the zoning map or Chapter descriptions. Not found in retrieved materials.
• Sign standards (district summary):
  • Wall signs: generally extremely limited (example: 1 sf in some single-family classifications). § 18.180.100.
  • Freestanding signs: rare; see Table entries and exempt sign rules. § 18.180.100, § 18.180.070.
• Where it applies: single‑family and rural parcels as mapped in Title 18. Verify parcel zoning. (Verify with the jurisdiction.) Not found in retrieved materials for full narrative.

Multi-family residential — RM, RH

• Typical context/purpose: multifamily developments and residential complexes (detailed purpose Not found in retrieved materials).
• Sign standards (district summary):
  • Wall signs: 0.5 sf per dwelling, up to maximum 25 sf (per building/tenant rules in Table). § 18.180.100.
  • Freestanding signs: limited; freestanding signs commonly limited to 5 ft height for residential entries or directional signs unless a sign program provides otherwise. § 18.180.100, § 18.180.110.
• Where it applies: apartment complexes, condominiums, residential overlay areas. Verify parcel classification. (Verify with the jurisdiction.)

North Todos Santos (downtown pocket) — (SFR, MF, Office)

• Special downtown built form; Table provides small allowed wall signage for residential and larger allowances for commercial storefronts. See Table 18.180.100 entries. § 18.180.100.
• Mixed rules reflect downtown pedestrian context; check Design Review (/us/california/concord/design-review) when replacing signs in the downtown core.

Commercial and Downtown categories — CO, CMX, NC, SC, RC, DP, DMX, WMX

• Typical context/purpose: neighborhood, community, regional and downtown commercial nodes (detailed purpose Not found in retrieved materials).
• Sign standards (district summary):
  • Wall/awning/projecting: generally allowed at 1 sf per linear foot of building frontage, with no sign required to be less than 20 sf in some classes (see Table). § 18.180.100.
  • Multi-tenant buildings: tenant wall signage often limited (example: 4 sf/tenant with a max cumulative 28 sf; building identification 8 sf). § 18.180.100.
  • Freestanding: often limited in number and height (setback 5 ft; small area caps unless an MSP allows larger area). § 18.180.100(B).
• Where it applies: shopping centers, Main Street and other commercial corridors. Master sign programs are common for multi-tenant commercial centers; see § 18.180.060.

Business park / Industrial — OBP, IBP, IMX, HI

• Typical context/purpose: offices, light industrial, heavy industrial (detailed purpose Not found in retrieved materials).
• Sign standards (district summary):
  • Building identification: typically 8 sf for identification signs; single‑tenant walls can use 0.5 sf per lineal foot of building frontage or 3% of wall surface, with a high maximum (e.g., 150 sf in some single‑tenant cases). § 18.180.100.
  • Freestanding: commonly capped at 20 sf, 5 ft setback and limited number unless an MSP allows more. § 18.180.100.
• Where it applies: business parks, industrial parcels; larger identity signage may be approved through sign plans or MSP. § 18.180.110 (use-specific) may also apply for vehicle‑oriented uses.

Public / Quasi-Public — PQP, OS, PR

• Sign standard: typically determined by a sign program for larger public sites; the table lists “to be determined by sign program” for many public uses. § 18.180.100.
• Example: bulletin boards, church/school signs, and hospital signage have specific entries in Table 18.180.110 with per‑sign area and height caps (e.g., church/school wall sign 25 sf, freestanding up to 50 sf with sign plan approval). § 18.180.110.

Quick Decision Table — most-used numeric standards

(These numbers are synthesized from Table 18.180.100 and Table 18.180.110; see the code for the full matrix and special-use exceptions.) § 18.180.100–110.

Sign plans, MSPs, and review process — practical notes

• Small projects or sign changes that meet the chapter rules may be approved administratively; sites with 2–5 signs require a sign plan and 6 or more signs require a master sign program. § 18.180.110 (notes).
• Sign plans / MSPs require design and site review and may be approved administratively if they meet standards; staff has limited authority to adjust up to 25%. Larger deviations require design review board or planning commission action. § 18.180.110 (notes), § 18.180.060.
• Design guidance: sign materials, scale, illumination and context must be compatible with building architecture and the site; see the sign design standards in § 18.180.140 and coordinate any facade changes with the broader Development Standards and Design Review processes. (/us/california/concord/development-standards) (/us/california/concord/design-review)

Checklist

• Confirm zoning district for the parcel and applicable district label (for example RM, CO, OBP) — verify map. § 18.180.100.
• Measure building frontage and compute allowable wall area (1 sf/lf or district formula) or apply per‑tenant cap. § 18.180.100.
• Determine number of signs: if 2–5 signs prepare a sign plan; if 6+ signs prepare a master sign program. § 18.180.110 (notes).
• Ensure freestanding sign is set back 5 ft from the right‑of‑way (unless a specific standard says otherwise). § 18.180.100(B).
• Check exempt signs rules (construction signs, address plaques, governmental signs) in § 18.180.070 to see if a permit is needed.
• Prepare materials/illumination details to comply with design standards in § 18.180.140; coordinate with any required Design Review. (/us/california/concord/design-review)
• If signs deviate more than 25% from standards, expect design review board or planning commission review — consult § 18.180.110.

Risks & Ambiguities

Plain-English Summary

Concord’s Development Code (Chapter 18.180) sets numeric caps and placement rules for signs by zoning district and by specific uses; small projects often get administrative approval, but shopping centers or projects with many signs must use a sign plan or master sign program. Read Table 18.180.100 and Table 18.180.110, confirm your zoning label, and plan for design review if you need deviations. § 18.180.100–110.
