Sign Permit

A sign permit is a government-issued authorization allowing a business or property owner to install, modify, or display a sign on a building or property. Issued by a local city or county planning or zoning department, it confirms that proposed signage complies with local regulations governing size, placement, lighting, and design. Most jurisdictions require a sign permit before any exterior business sign is installed.

How a sign permit works

An applicant submits a sign permit application to the local planning, zoning, or building department, typically including a site plan, sign dimensions, materials, proposed location, and a design rendering. The reviewing authority evaluates the application against the local sign ordinance, which governs what types of signs are allowed in a given zone, how large they can be, and whether illumination is permitted.

The general process follows these steps:

1. Review local sign ordinance requirements for the property's zoning classification.
2. Prepare and submit a sign permit application, including the required drawings and specifications.
3. Pay the applicable permit fee.
4. Await review and approval from the local authority.
5. Install the sign according to the approved plans.
6. Complete any required post-installation inspection.

Why a sign permit matters

Installing a sign without the required permit exposes a business to enforcement action, including fines, forced removal, or a hold on other business licenses until the violation is resolved. For businesses opening a new location, an unpermitted sign can delay operations and create complications with landlords who may be held jointly responsible for code violations.

The permitting process also ensures that signs are structurally sound and safely installed, which is particularly important for large exterior signs, illuminated signs, or signs mounted at high up.

Common uses

Sign permits apply across a wide range of signage formats.

• Retail storefronts: A backlit channel letter sign above an entrance requires a permit before installation begins
• Restaurant awnings: An awning that includes a business name or logo typically qualifies as a sign under local ordinances
• Freestanding monument signs: Ground-level signs identifying tenant businesses require permits specifying height, setback, and square footage
• Digital or electronic signs: LED message boards are subject to additional regulations regarding brightness, animation, and hours of operation, and they always require a permit

Key characteristics

Sign permits are local permits, meaning requirements vary significantly by city, county, and zoning district. A sign permitted in a commercial corridor may not be allowed in a mixed-use or residential-adjacent zone.

Fees are generally calculated based on the sign's size or value. If a business moves locations or wants to change the size or design of an existing sign, a new permit can be required. Most sign permits do not expire once the sign is installed, though some jurisdictions require renewal for temporary signage or electronic displays.

Sign permit vs. building permit

A sign permit is distinct from a building permit, which covers structural construction or renovation work. Both may be required when a sign needs new electrical wiring for illumination, since illuminated signs must also comply with applicable electrical safety codes.

FAQs about sign permits

Does changing the text or graphics on an existing sign require a new permit?

It depends on the jurisdiction and scope of the change. Updating copy on a sign of the same size and type often does not require a new permit, but changing dimensions, adding illumination, or altering the structure typically does. Always check with your local laws though, as they can vary widely.

What happens if a sign was installed without a permit before a business purchased or leased the property?

The violation follows the property, and the current occupant or owner can be held responsible. Resolving it typically requires obtaining a retroactive permit, if the sign meets current ordinance requirements, or removing it.

Are there signs that do not require a permit?

Most jurisdictions exempt certain categories, such as small window signs below a specified square footage, real estate signs, and temporary political signs. Specific exemptions vary by local ordinance, so confirming with the planning or zoning department before assuming a sign is exempt is the safest approach.
