Basement permit in St. Petersburg, FL
Yes — you need a permit for basement work in St. Petersburg.
Finishing a basement or converting it into living space is Building work (framing, egress, occupancy change). FBC 105.2 exempts no Building work and St. Petersburg has no city Building exemption, so it needs a building permit; only purely cosmetic repairs would be exempt. The floodplain lowest-floor sections shown reference 'basement' for inspection sequencing, not as a permit exemption.

How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the St. Petersburg building department.
- Pay the permit fee when the permit is issued. Work done before that isn't covered.
- Book each inspection listed on the permit as the job reaches that stage.
Either of you can pull it. When a contractor does the work, it is normally their job.
If you skip it
St. Petersburg's code doesn't set a specific fine for this work. In practice the department can issue a stop-work order, and unpermitted work tends to surface during a sale, when the buyer's inspector or the title company asks for it.
