The county process
Pinellas registers associations on its Access Portal and applies the 30-year trigger to condo and co-op buildings of three stories or more (Pinellas County, condo milestone inspections). Larger cities outside that list, St. Petersburg among them, run their own process.
Why the flood rule matters to a SIRS
The county page reminds owners that FEMA's 49% rule applies to repairs in a Special Flood Hazard Area. Once improvements pass half the building's value, the work can trigger full flood-code compliance, which changes what a "replacement" costs. A SIRS for a beach building should say which items, if replaced, could push the building over that line.
The state rule, unchanged by county
Whatever the local program, the SIRS itself is state law. Every condo or co-op building of three habitable stories or more in Pinellas County needs one at least every 10 years, covering the eight statute items, signed by one of the four credentials, with reserves that owners cannot waive. The deadlines page has the dates.
