Boca Grande sits at the south end of Gasparilla Island, reached by the causeway and its swing bridge. It is an old phosphate port turned high-value winter community, and its downtown is a National Register historic district.
The rule that matters here is that the Boca Grande Historic Preservation Board is a decision-making body, not an advisory one. It implements the Lee County historic ordinance for designated properties, and the Gasparilla Island Conservation District limits development on top of that. Roof material and colour standards sit in the county land development code, and they are worth checking before anything is ordered.
