Do I need a permit for addition or structural alteration in Miami Gardens?
Yes. In Florida, addition or structural alteration generally requires a permit, and Miami Gardens is no exception.
A building permit is required for any addition and for structural alterations such as removing or altering load-bearing walls, changing the footprint, or altering the roof structure. The Florida Building Code only exempts ordinary minor repairs that do not cut into walls or remove load-bearing supports, so structural work is never exempt. Additions usually trigger zoning review and, in flood areas, elevation requirements.
Local and county notes for Miami Gardens
Structural work is specifically excluded from the HB 803 $7,500 exemption. Signed and sealed engineered plans are commonly required. Additions often trigger setback, lot-coverage, and floodplain review. The City of Miami Gardens Building Division applies the rule that a permit is required to construct, enlarge, alter, repair, move, remove, or demolish any building or structure, so a room addition or structural alteration needs a full permit package and plan review. Because Miami Gardens is in the Miami-Dade High Velocity Hurricane Zone (HVHZ), structural and envelope work is reviewed to HVHZ wind-load standards and some products may need a Miami-Dade County Notice of Acceptance or Florida Product Approval. The city applies the Florida Building Code, the Miami Gardens Municode, and Miami-Dade County Code Chapter 8, and a Notice of Commencement is required once the job passes the state cost threshold. An addition is designed to full HVHZ structural standards, which normally means signed and sealed engineering and a longer plan review than elsewhere in Florida. Your city issues the permit, not the county. Miami-Dade County's own building department serves the unincorporated area, while each municipality runs its own building department, and the county Board of Rules and Appeals interprets the code across all of them.
