A sign permit is an official approval from your local government — typically the city or county planning or building department — that authorizes you to install, modify, or display a sign at a specific location. Almost every municipality in the United States requires permits for permanent commercial signs. The permit confirms your sign complies with local zoning, size limits, setback requirements, illumination rules, and structural safety standards.
Sign permits are issued at the city or county level, not the state level. State laws generally set outer limits and definitions, but the actual permit process and rules are hyperlocal.
Sign permit fees vary widely. Small municipalities may charge a flat rate of $25–$75. Larger cities typically use a base fee ($50–$150) plus a per-square-foot charge (often $1–$5 per sq ft). Illuminated or electrical signs require a separate electrical permit, adding $50–$200. Complex signs (LED displays, large monuments) can require engineering review, pushing total fees above $500.
Our fee estimator tool can give you a ballpark based on your sign type and location.
It depends on your municipality's definition of a "sign" and their coverage threshold. Many cities exempt window signs that cover less than 25–30% of the window area. Others count all window lettering toward your total allowed signage. Illuminated window signs almost always require a permit. Applied vinyl that covers more than a third of a window is treated as a sign in most jurisdictions.

Code enforcement can order immediate removal, issue daily fines (commonly $100–$500/day), and in some cities place a lien on your property or business license. Practical consequences include: difficulty selling your business (title searches uncover sign violations), challenges with lease renewals, and liability if the sign causes injury. Most cities offer a grace period to bring signs into compliance if you voluntarily come forward. See: What Happens If You Skip the Sign Permit?
Simple wall sign permits in small cities often take 3–7 business days. Larger municipalities with full plan review departments typically take 2–4 weeks. Cities with historic districts, design review boards, or complex zoning (like San Francisco, New York, or Savannah) can take 6–10 weeks. Some cities now offer over-the-counter approval for smaller signs. See our full guide: How Long Does a Sign Permit Take?
For smaller wall signs and most non-electrical signs, business owners or property owners can apply directly. For illuminated, large, or structurally complex signs, most jurisdictions require a licensed sign contractor and a state-licensed electrician to pull the electrical permit. Some cities (notably New York City) require a licensed sign hanger for any sign over a minimum size. Check your local requirements before hiring.
We're not a sign company. We don't sell signs, install them, or earn commissions on permits. This site was built because finding clear, unbiased sign permit information was harder than it should be — and the sites that did cover it were all trying to sell something. Every guide here is written from primary sources: municipal codes, planning department publications, and permit office documentation.
