Who actually issues your plumbing permit in Broward or Miami-Dade

Most people picture one county government handing out permits under one uniform rulebook. Neither piece of that picture survives contact with how Broward and Miami-Dade are actually structured, and understanding the real shape of each is worth doing before a job gets scheduled.

Broward: thirty-one cities answering to one code board

Broward does something unusual for a Florida county. A single body, the Broward County Board of Rules and Appeals, sits above all thirty-one municipalities as the regional referee on how the code gets interpreted and which products get approved. That board reviews proposed amendments to the building and fire codes, rules on appeals against local building and fire officials, and settles disputes over what a code section actually means once local officials disagree. No city and no county commissioner can write a rule that contradicts what the board has already adopted.

In practice, the permit itself still comes from the property’s own city, but the code being enforced and how it gets interpreted are set at the county level. That means a disputed code question in Broward has somewhere specific to go, and an appeal there is a genuine option rather than a theoretical one.

Miami-Dade: the folio settles it, and utilities weigh in separately

Miami-Dade has thirty-five municipalities, each running its own building department. The county itself only handles permitting for the unincorporated municipal service area, and it draws that line plainly: the county process applies solely to properties whose folio starts with thirty. Everything else belongs to the relevant city, and the county points owners toward the property appraiser or the municipal code to work out which category applies to them.

Separately, the county requires a water and sewer department review wherever work touches water or sewer capacity or connections. So a sewer lateral, a service line, or any job that changes what a property draws from the system will typically need utility sign-off on top of the municipal permit. That is simply how the county process runs, not an added delay somebody invented.

What actually needs a permit

More work falls under this than most homeowners guess. Local codes here cast a wide net over what counts as plumbing work needing a permit: building new lines, expanding them, changing them, taking them out, swapping their function, or putting in a replacement. That breadth is intentional, catching plenty of what feels like routine upkeep. A sewer line getting repaired or replaced is inspected work almost everywhere. A water heater going in is treated the same way in most cities on this list, since one job simultaneously governs safety, efficiency, pressure and how the unit vents.

What usually stays off the permit list is a fixture repair that does not touch the system around it: swapping a cartridge, a flapper, a hose bib, a trap washer. The real dividing line sits at the point where fixing something becomes altering the system it is part of, and any building department will answer that specific question for free before work starts.

Why skipping the permit becomes a problem later, not now

Skipping it causes no visible problem on the day, which is exactly why the shortcut survives. The reckoning tends to arrive three different ways: through a buyer’s inspector finding work with no paper trail and no proof it met code, through a future permit application that stumbles on earlier work nobody ever reviewed, or through an insurance adjuster asking who actually did the job and how.

A less obvious reason matters too: the permit and inspection sequence is the only outside check that work ever receives, and a contractor eager to bypass it is opting out of the one step that was never theirs to waive.

Some cities add still another layer

Coral Gables can pull in a historic preservation review on top of the building department and the county utility desk, three separate bodies weighing in on a single job. Boca Raton is known for development codes stricter than its neighbors’, worth knowing before scheduling anything that touches the exterior of a property. Several smaller municipalities contract pieces of the process out, or send utility questions to a neighboring provider entirely. None of this causes a problem when it is known ahead of time, and every bit of it causes a delay when it is discovered halfway through the job. The page for each city on this site names the authority that actually governs it.
