Searching for sign permit information online is frustrating. Most results come from sign companies — businesses that profit from selling and installing signs. Their content is helpful in places, but it's written with a commercial interest. The gap between "do I need a permit?" and "here's exactly how to get one at your address" is still enormous.
SignPermitGuide exists to fill that gap with independent, vendor-free information. We're not a sign company. We don't sell signs, install them, or earn commissions on permits or sign products. We don't have any financial relationship with sign vendors, local governments, or permit services.
We cover U.S. business sign permit requirements: when permits are required, what's exempt, how to apply, what the process looks like, typical fees, common problems, and step-by-step guides for specific cities. Our content is organized by topic and by location so you can find the information relevant to your specific situation.
Every guide on this site is written from primary sources: municipal codes, planning department publications, permit office documentation, and public records. We don't rely on sign company websites or aggregated content as primary sources. When rules change, we update our guides.
We acknowledge that sign rules change frequently and vary by municipality. We cannot guarantee that any piece of information on this site is current for your specific location on any given day. That's why every guide includes instructions for verifying with your local planning department — because that's the only definitive source.
We are not lawyers, architects, engineers, or licensed sign contractors. Nothing on this site constitutes legal, engineering, or professional permitting advice. We provide information; you make decisions based on confirmation from the appropriate authorities.
We cover the United States only. Sign permit rules in Canada, the UK, and other countries are not covered here.
