St. Petersburg, FL Sign Regulations: Window Signs (2026)

10 of the Sign Code lists 'window signs, non-illuminated' among the sign types exempt from the sign permitting process. The cap is a coverage ratio, not a square-footage number: the cumulative area of every non-illuminated sign placed in a window can't exceed 50 percent of that window's total pane area, measured window by window rather than building-wide. The Code defines a 'window sign' broadly as any sign located on a window, or within a building or other enclosed structure, that is visible from outside through the window or any other opening, so a poster or banner hung just inside the glass counts the same as vinyl lettering applied directly to it.

6. Being 'exempt from the permitting process' does not mean a window sign is exempt from every rule in the Sign Code: exempt sign types still have to meet the Code's construction, illumination, placement, safety and nonconformity requirements, and remain subject to other public health, safety and welfare regulations outside the sign chapter. Certain uses layer on tighter caps, for example, adult use establishments must count window signage as part of their overall allowed signage rather than treating it as exempt, and their total signage is capped at half of what the general sign section allows.
