In most US cities, yes. Cities generally require a sign permit before a permanent exterior sign is installed, and illuminated signs also have electrical requirements. Rules vary by city and zoning district, so check your local sign ordinance or call the building or planning department before you order.

Most applications need a completed permit form, a landlord authorization letter, professional shop drawings (an elevation view, a section view showing how the sign mounts, and electrical specs), UL listing information for illuminated signs, and a materials list. BASISSIGN provides a permit-ready engineering packet with orders. Exact requirements vary by city.

Application fees typically run about 50 to 300 dollars, depending on the city and the size of the sign. Check your local fee schedule for any additional review or inspection charges.

Some suburbs approve over the counter the same day when the paperwork is complete. Standard review usually takes 2 to 4 weeks, and historic districts can take 1 to 3 months. Submitting complete drawings the first time is the best way to avoid delays.

A sign ordinance is your city’s zoning rule for signs. It typically limits total sign area (often tied to storefront width), how far a sign can project, and illumination, such as banning flashing lights in some zones. A common guideline is about 1.5 square feet of sign per linear foot of frontage, but confirm your city’s exact limits.

Usually yes. Cities generally want a letter of authorization from the property owner before accepting a sign permit application. Send your sign design to your landlord first and get a signed approval letter, which also confirms your lease allows the size and placement.

In many cases yes, if you have the right documents from your sign manufacturer. Small towns often accept applications at the building or planning department counter, while larger cities usually use online plan review portals. An expediter or attorney is not always required.

The city can issue fines and require you to remove the sign, which can mean losing the cost of both the sign and the installation. Penalties vary by city, so get approval before installation begins.

Inspectors need proof that an illuminated sign meets electrical safety standards, including the National Electrical Code. A UL listing and the manufacturer’s UL information show the sign was built and tested to those standards, which supports approval and the final inspection. See our UL 48 certification guide.

You receive approval to proceed, install the sign, then call for a final inspection. Inspectors typically check that the sign is securely mounted and that the UL label is visible. Our installation resources cover the mounting steps, and you can request a quote with permit-ready details.
