We’re Available to Help: A permit reviewer isn’t trying to slow your project down. They’re checking three things: is this sign allowed here, is it safe, and will it cause problems for neighbors or drivers. Once you know that, the paperwork stops feeling random and starts feeling like a checklist you can just work through.
Most delays we see trace back to one missing document, not a complicated review process. Here’s what to have ready before you submit, based on what comes up again and again with U.S. permit offices. For the bigger picture on zoning and sign codes, we’ve covered that separately in our permits and zoning overview.
Sign, structural, or electrical: know which permit(s) apply
Depending on your sign type and city, your project might touch one, two, or all three of these:
- Sign permit: planning or zoning review
- Building or structural permit: for monument or pylon structures, or major modifications
- Electrical permit: power, disconnects, wiring
Some cities fold these into a single packet. Others send them to separate departments with separate timelines. A common mistake is assuming one approval covers everything, then finding out the electrical inspection is a completely different process on its own clock.
What a typical permit packet includes
Site plan. Property lines, street frontage, building footprint, proposed sign location, and setback distances. This is usually the first thing a reviewer checks, since it decides whether the sign is even allowed in that spot before anything else gets evaluated.
Elevation drawings. Overall height and width, mounting height, clearance from grade, and projection from the building if it’s wall-mounted.
Sign area calculations. Most codes cap total allowable sign area, so spell out the face area, whether it’s single or double-faced, and any additional panels. Doing this math for the reviewer ahead of time, instead of leaving them to measure a drawing, tends to move things faster.
Structural details, for ground-mounted signs. Foundation details, anchoring method, and engineering notes, sometimes stamped by a licensed engineer depending on the jurisdiction and size.
Electrical notes. Load requirements, disconnect location, and a clear breakdown of who’s doing what. Projects stall most often when nobody has claimed this piece. If you want to line it up early, our installation and maintenance team can help coordinate scope before submission.
Product cut sheets. Manufacturer info, model, dimensions, electrical requirements and, for digital displays, confirmation of brightness control.
A brightness or dimming statement. If it’s an electronic message center, many cities want written confirmation it will dim automatically at night and stay within local brightness rules. This is one of the more common sticking points, so address it up front rather than waiting for a reviewer to ask.
Site photos. A few clear shots of the building or lot help a reviewer picture the context without a site visit.
Property owner authorization, if you lease your space.
Before you submit
- Sign type confirmed as allowed under local zoning or the sign district
- Site plan with sign location and setbacks
- Elevation drawings with dimensions and mounting height
- Sign area calculations, clearly labeled
- Structural plan for ground-mounted signs
- Electrical notes: load, disconnect location, electrician scope
- Product spec sheet
- Brightness or dimming plan for electronic message centers
- Site photos
- Property owner authorization, if applicable
Five things that speed up an approval
Ask for the city’s own checklist first: many permitting offices publish a one-pager, and matching your packet to it line by line beats guessing. Submit one clean, labeled packet instead of a pile of loose files; an easier read for the reviewer usually means a faster one. Don’t skip the brightness plan, since addressing nighttime dimming up front heads off complaints and follow-up requests later. Decide early who owns each document, since most delays come down to one missing piece nobody realized was theirs. And work with a vendor who’s done this before: outdoor LED signs, especially digital ones, tend to need the most documentation, and a team that already knows what your city expects saves real time.
FAQs
How long do LED sign permits take? It depends heavily on the city and sign type. A complete, well-organized packet moves faster than one that gets bounced back for missing information.
Do I always need a separate electrical permit? Often, yes, particularly for new circuits or disconnects. Confirm with your electrician and local building department, since it varies by jurisdiction.
What’s the most common reason applications get kicked back? Missing drawings, unclear sign area math, or an incomplete site plan. Those three account for most of what we see.
