/ Miami-Dade · How to apply

Plans are not reviewed until the upfront fees are paid.

Unincorporated Miami-Dade only — folios that start with 30. Plans are not reviewed until upfront fees are paid. Same-amperage AC still needs a mechanical permit. HVAC repair or replacement under $15,000 is the County’s published Notice of Commencement exception.

Educational restatement of Miami-Dade’s “How to Apply for a Permit” page. Municipalities have their own building officials. Confirm the live County page. Pair with exemptions / HB 803.

Permits are typically required for new structures, pools, additions, new plumbing/electrical/mechanical AC work, exterior replacements (windows, doors, siding, roof), and interior work that alters electrical or plumbing — including hot-water heater or gas-appliance replacement. Paint, wallpaper, a ceiling fan in an existing outlet, portable playground equipment, and resurfacing an interior floor are listed as not needing a building permit — still confirm exemptions.

Started before the process number

Work before issuance is a penalty path under IMC 108 as adopted. Do not mobilize on a UP#.

What to send

Folio (does it start with 30?), process or UP number if you have one, and the comments PDF.

If the portal is sitting on unpaid upfront fees

Send the UP# or process number. Masterbuild will say whether the set is even in review — or this is still intake.
