Frequently asked questions — Pinellas County, Florida
How did Hurricane Helene affect permits in Pinellas?
Hurricane Helene (September 2024) caused catastrophic storm surge in Pinellas County - among the worst in the county's history. The Substantial Improvement rule is being strictly applied: if storm damage repairs exceed 50% of pre-storm value, the structure must be elevated to current flood elevation requirements. The county established a hotline for storm damage permit assistance.
What makes Pinellas permitting unique?
Pinellas is the most densely developed county in Florida with essentially no undeveloped land. This means most construction is redevelopment or renovation, not new construction. Setback variances and non-conforming structure rules are very common. The county also has the most coastal exposure of any major Florida county - almost every neighborhood is close to water.
Do I need a permit to rebuild a seawall in Pinellas?
Yes - and it's a two-permit process. You need a Pinellas County building permit AND a Florida Department of Environmental Protection (FDEP) coastal construction permit. The DEP process can take 2-6 months. Always start the DEP application first.
Can I rent an ADU in Pinellas County?
SB 1586 (2023) limits municipalities from banning ADUs. However, short-term rental rules vary significantly by city in Pinellas - some cities (St. Pete Beach, Treasure Island) heavily regulate vacation rentals. If you plan to rent your ADU, confirm local short-term rental ordinances before building.
