Sign permits
Putting Up a Sign or Banner in Downtown Nacogdoches
The historic red-brick streets and National Register storefronts downtown are part of why the city keeps a close eye on signage, so don't order a business sign or hang a banner first and sort the paperwork out later. A standard sign permit comes through Inspection Services. The application lives on the city's forms page, right alongside the building and trade permits, and you can file online.
The path forks when you want something the ordinary rules don't cover. A sign that needs more height, more area, or a placement the code wouldn't normally allow takes a sign variance, and that's a Planning & Zoning matter, not an Inspections one. A temporary banner strung over a street has its own separate packet through Planning & Zoning too.
So the practical question is which one you're asking for. Routine new sign that meets code: Inspection Services, 936-559-2551. Need an exception, or a temporary overhead banner: Planning & Zoning. Sort that out before the sign shop starts fabricating, because a finished sign that doesn't fit the code is an expensive thing to redo.
