Do I need a permit for interior remodeling in Miami?
Most likely yes. Interior remodeling usually requires a permit in Florida. Confirm the specifics with Miami.
Cosmetic interior work such as painting, flooring, cabinets, and drywall patching generally does not need a permit, while remodeling that involves electrical, plumbing, mechanical, gas, or structural changes does. Florida HB 803, effective July 1 2026, exempts single-family work under $7,500 from a building permit, but it excludes those five trades and does not apply in flood-hazard areas. Most permit-worthy remodels involve one of those trades.
Local and county notes for Miami
Electrical, plumbing, mechanical, gas, and structural work still need a permit regardless of cost. HB 803 bars splitting a project to stay under $7,500 and does not apply in flood-hazard areas. Local departments implement HB 803 individually, so confirm the policy in your jurisdiction. In single-family homes and duplexes the City of Miami exempts purely cosmetic work such as painting (with no stucco work), wallpaper, floor finishes, and cabinet and countertop replacement, as long as there is no change to plumbing, electrical wiring, or load-bearing walls. As soon as a remodel moves a wall or alters plumbing, electrical, or mechanical systems, a permit is required; kitchen and bathroom remodels are listed as permit categories in the City of Miami Residential Permit Guide. When unsure whether your scope crosses from exempt cosmetic work into permitted work, confirm with the City of Miami Building Department before starting. A remodel that moves walls or includes electrical, plumbing, or mechanical work falls outside cosmetic exemptions, which cover finishes such as paint, flooring, trim, and cabinets. Each trade normally needs its own permit and inspection on top of the building permit, and removing or altering a load bearing wall usually requires a beam detail or engineering before the work is approved. Opening walls in an older home can trigger separate lead paint, asbestos, and smoke alarm requirements, so raise those with your department at application time. Every address in this county sits inside the Florida Building Code High Velocity Hurricane Zone, the strictest wind construction standard in the state, so materials and methods face requirements that do not apply 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.
