Do You Need a Permit?
Conditional — More Information NeededA permit is generally required for air-conditioning installation and change-out work in Miami Beach. Certain minor repairs and replacement of an existing previously permitted window A/C unit may be exempt. Miami Beach treats an eligible exact A/C change-out (same-size equipment, no ductwork changes) as an over-the-counter / same-day permit type with reduced paperwork, but a permit is still required.

Common Questions
Do I need a permit to replace an AC unit?
Yes. Even an eligible same-size, no-ductwork-change exact change-out — which qualifies for Miami Beach's simplified same-day permit type — still needs a permit.
Do minor AC repairs require a permit?
Certain minor repairs, and replacement of an existing, previously permitted window A/C unit, may be exempt.
Permit Fees
Fees vary by project scope. See the official City of Miami Beach Building Department fee schedule. Most residential AC/HVAC repair or replacement contracts are exempt from the Notice of Commencement filing requirement under Florida Statute 713.135, which does not apply to HVAC repair/replacement contracts valued under $15,000.
Review Time
Varies by project and plan-review workload
