Miami-Dade County has some of the strictest building codes in the country—for good reason. After Hurricane Andrew's devastation in 1992, the county implemented rigorous standards to protect homes. Here's what Miami homeowners need to know about roofing permits.
Why Miami-Dade Codes Are Different
Hurricane Andrew's Legacy
- 1992 hurricane exposed major building failures
- Miami-Dade created High-Velocity Hurricane Zone (HVHZ)
- Products must be specifically approved for HVHZ
- Installation methods strictly regulated
The Result

- Roofs built to higher standards
- Better storm performance documented
- Higher initial costs, better protection
When Is a Permit Required?
Always Required
- Full roof replacement
- Re-roofing (new layer over existing)
- Structural repairs

May Not Require Permit
- Minor repairs (some exceptions)
