Deck permit in Miami, FL
Yes — you need a permit for deck work in Miami.
You need a building permit to build or replace a deck, attached or freestanding. Decks are not on Miami's exempt list in Sec. 10-5, and the state list in FBC 105.2 has no Building category, so no deck size is exempt. The city's inspection rules back this up: Sec. 10-10 calls for an inspection of the under-deck area and a deck inspection before you install the decking material, which only happens on permitted work.

How to pull the permit
- Put together a site plan showing where the work goes, with dimensions.
- Apply through the Miami building department.
- Pay the permit fee when the permit is issued. Work done before that isn't covered.
- Book each inspection listed on the permit as the job reaches that stage.
If you skip it
If you do the work without the required permit, the city can post a stop work order and charge penalties.

Questions people ask
How much does a deck permit cost in Miami?
The code names no deck-specific amount. For homes of up to three dwelling units, the permit fee is figured from the estimated construction cost, including labor and materials (Sec. 10-18). Current amounts are on the city site at miamigov.com.. Valuation-based fees mean the number depends on what the job is worth, so the department quotes it when you apply.
I already built it without a permit. What now?
Miami can issue a stop-work order and require you to apply after the fact, sometimes with an extra fee. Work that was covered up may have to be opened for inspection. Full walkthrough here.
Does unpermitted work cause problems when selling the house?
Often, yes. A buyer's inspector or the title company may flag it, and lenders can balk at financing a home with open or missing permits. What to do about it.
