How St. Petersburg Handles Sign Regulations: A Practical Guide
St. Petersburg maintains 143 local ordinances across all categories, and 3 of those deal specifically with sign regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where St. Petersburg falls on the strict-to-permissive spectrum compared to other cities.
Garage Sale Signs
St. Petersburg limits garage-sale advertising to one sign of no more than four square feet per property under City Code § 16.50.160.4, and that sign can only be displayed during daylight hours on the days a garage sale is legally allowed to run.
Key details: Signs allowed: One per property. Max sign size: 4 square feet. Display timing: Daylight hours only. Display days: Only on legally allowed sale days.
Posting more than one sign, exceeding the four-square-foot size cap, or leaving a sign displayed outside daylight hours or on a day the underlying garage sale isn't permitted (Monday through Thursday, or outside the four-sales-a-year/60-day spacing limits) violates § 16.50.160.4 and § 16.50.160.5 and is a citable property-maintenance violation.
If you are coming from a city with tighter rules, you will find St. Petersburg gives residents more flexibility on garage sale signs.
Window Signs
St. Petersburg caps non-illuminated window signs at 50 percent of a window's total pane area under City Code Section 16.40.120.10, and a sign within that limit is exempt from sign permitting, but an illuminated window sign counts against the site's overall wall-sign allowance instead.
Key details: Coverage cap: 50% of total window pane area. Basis: non-illuminated window signs only. Illuminated window signs: count as wall signage instead. Permitting status: exempt from sign permit process. Adult-use exception: window signage counted, not exempt.
A non-illuminated window display that exceeds the 50 percent pane-area cap forfeits its exempt status and must come into compliance with the sign code's general permitting and wall-signage requirements; enforcement runs through the City's Code Enforcement Board process under Chapter 9, which can issue a notice of violation and refer an uncorrected sign for a hearing and fine.
Digital Billboards
St. Petersburg only allows new digital billboards along the interstate, and only under a City agreement that removes at least ten static billboards for every converted digital face. City Code Section 16.40.120.8 caps them at 25 feet tall and roughly 14 by 48 feet, spaced at least 2,500 feet apart.
Key details: Location limit: within 100 ft of interstate right-of-way. Spacing minimum: 2,500 ft apart, same direction. Max sign face: ~14 ft x 48 ft. Max height: 25 ft or replaced billboard's height. Dwell time: at least 10 seconds per message.
A violation of the lighting, brightness, message-sequencing or dwell-time standards gets a six-hour cure window once the City issues a notice under Chapter 9, tolled while the display is turned off to fix it. Fines start at $1,000 per day for a first violation, $2,500 per day for a second, and $5,000 per day for a third and each subsequent violation, set under the enhanced Code Enforcement Board authority of F.S. § 162.09(2)(d).
This is not one of those rules that cities tend to ignore. St. Petersburg actively enforces its digital billboards requirements.
The Bottom Line
St. Petersburg's sign regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming St. Petersburg is broadly strict or permissive.
Keep in mind that St. Petersburg can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
