Do I need a permit?
Only the building department with jurisdiction can answer for your address. This tool routes you to the published City of Miami or Miami-Dade guidance we cite.
Guidance — not a permit decision
The City of Miami Building Department treats central air-conditioning replacement as permitted mechanical work. Homeowners can start from the City's residential permit guide (A/C unit items) and iBuild. Confirm current checklists with the City — this page does not issue permits.
Fees are published in municipal and County fee schedules and change. We do not reprint dollar amounts here. Ask the contractor whether the permit fee is included in the quote, then confirm the current schedule with the department that will issue the permit.
