It depends
It depends on scope. Like-for-like cosmetic work in Miami is often exempt, but a permit is required as soon as you change structure, plumbing, electrical or the building envelope.
High-Velocity Hurricane Zone (HVHZ) rules apply across Miami-Dade, which raises product-approval and inspection requirements for roofs, windows and shutters.
