Navigate local signage codes, permit requirements, and ADA compliance considerations for commercial signage projects.
By Focus Graphics · Updated
Signage regulations exist to maintain community aesthetics, ensure safety, and provide accessibility. Installing non-compliant signage can result in fines, forced removal, and project delays. Understanding local codes early in the design process saves time and money.
• This is a planning overview, not a complete code review or legal advice. Requirements depend on the property, sign type, jurisdiction, and applicable accessibility standards.
• For Irvine projects, ask the City Planning Counter to confirm the rules for your property and proposed sign before production. Other cities have their own approval processes.
Check the applicable sign ordinance, property sign program, and permit requirements before attaching signage to a facade.
Height, setback, and size restrictions vary widely by zone.
Often have additional electrical permit requirements and brightness restrictions.
Banners, A-frames, and promotional signs may have duration limits and permit exemptions.
Confirm any vehicle, parking, or advertising restrictions that apply to your intended use and location.
• Ask the local authority about current review timelines before setting an installation date
• Your sign company should be familiar with local requirements
• Historic districts often have stricter design review processes
Maximum square footage often tied to building frontage or lot size.
Confirm the height limit for the specific zone, property, and sign type; there is no single limit for all locations.
Minimum distance from property lines, streets, and other structures.
Number of signs per business or per street frontage.
Some areas prohibit certain imagery or require business identification.
Permanent room identification, directional signs, and informational signs have different visual and tactile requirements. Check the applicable sign category and exceptions.
Review character size, style, spacing, contrast, non-glare finish, and Braille requirements in the Access Board guidance linked below.
Pictograms identifying permanent rooms or spaces have field-size and tactile text-descriptor requirements; not every pictogram is treated the same way.
Tactile character baselines generally fall within 48–60 inches above the floor. Door location, clear floor space, and applicable exceptions must also be checked.
• Use the full applicable accessibility standards, not this checklist alone, to evaluate a sign package
• Confirm state and local requirements in addition to federal standards
• Work with a signage professional experienced in ADA compliance
