Sign Permit: State-by-State Guide

Sign Permit applies to commercial businesses installing exterior signage. Who issues it is the first thing that changes at the state line — sometimes a state agency, often a city or county. Each state page below names the office we verified for that state, or says plainly that we could not.

Typical cost (US range)
$50–$800
Typical timeline
7–45 days
Renewal
Usually none — the permit covers the sign until you change it.

Who issues this across the US

51 jurisdictions issue this locally.

What varies: allowed size and height, whether illumination is permitted, review time, and whether a separate electrical permit is needed.
