St. Petersburg FAQ
Does St. Petersburg charge impact fees on ADUs?
Yes, but at scaled rates. Categories include transportation, parks, water, wastewater, fire-rescue, plus Pinellas County School impact fees collected at the county level. ADUs sharing existing utility service with the principal dwelling often see significantly reduced water and wastewater connection charges. Total impact fees on a small ADU vary widely depending on location and shared-utility status.
Can St. Pete raise ADU impact fees every year?
No. Fla. Stat. §163.31801, as amended by HB 337 (2021), caps annual impact-fee increases. Generally a municipality cannot increase impact fees more than 25% over two years or 50% over four years, with phased adoption, prior infrastructure-needs studies, and public notice. Increases above the caps require extraordinary circumstance findings supported by data.
