Dallas sizes your attached sign as a share of your building facade — and an oversized or unpermitted sign gets bounced or cited. Enter your storefront wall size and get a clear read before you pay for fabrication.
This checks attached (wall) premise signs in Dallas business zoning districts. Detached/pole signs, billboards, and special sign districts (Downtown, Arts District, Deep Ellum) route to a pro.

How Dallas sizes your sign
Dallas takes a different approach than most big cities. Instead of tying your sign to street frontage, the Development Code (Article VII) limits an attached premise sign to 15% of the facade it's mounted on for streamlined (director) review. Go bigger and you're pushed into committee review — slower, costlier, and easy to get rejected. A permit is required for any sign over 20 sq ft, and signs over 100 sq ft trigger public notification.
This tool figures your facade area from your wall dimensions, applies the 15% rule, and tells you where your plan stands before you commit.
Questions owners ask
What counts as my "facade"?
The area of the building wall your sign is mounted on — width × height. The attached-sign limit is a percentage of that.
Pole or monument (detached) sign?
Detached signs follow separate rules (height, setback, spacing) and aren't covered here — we'll route you to a pro for those.
Digital / LED display?
Digital and changeable-message displays face separate restrictions (§51A-7.216) and many districts limit them. This screen covers static/illuminated attached signs.
Special sign district?
Downtown, Arts District, West End, Deep Ellum and others override these rules with committee review. If your address is in one, confirm with a pro.
Is this an official ruling?
No. It's a first-pass risk filter on the public code, not a permit or legal advice. Final dimensions are confirmed by Dallas Building Inspection and a licensed sign contractor.
