Do I Need a Permit to Replace Windows in Miami-Dade?

When a permit is usually required

In Miami-Dade, the answer to "do I need a permit to replace windows" is almost always yes. HVHZ rules require documented product approval and installation inspection for every unit installed on the exterior envelope.

• Replacing any existing exterior window, even like-for-like impact.
• Installing new windows in an existing opening.
• Enlarging or reducing an existing opening.
• Adding a new window in a previously solid wall.
• Replacing a sliding glass door or French door on an exterior wall.
• Any impact-rated storefront or fixed glazing.
• Fenestration on additions, garage conversions, or ADUs.

When a permit may not be required

There is a narrow set of interior-only glazing work that may not require a permit, though local jurisdictions apply this narrowly.

• Interior partition glazing that does not penetrate the exterior envelope.
• Replacing interior door glazing panels.
• Repairing broken glass in an existing frame without altering the frame (some jurisdictions still require a repair permit).

Miami-Dade / South Florida considerations

Miami-Dade window permits are one of the most standardized permit types in the county, but a few HVHZ specifics catch homeowners and contractors off guard.

• Miami-Dade Notice of Acceptance (NOA) — every window and sliding door installed in the county must have a current NOA, and the installation must follow the manufacturer's approved installation drawings including anchor spacing and buck detail.
• Product Approval — non-HVHZ counties accept statewide Florida Product Approval; Miami-Dade also accepts these but the NOA path is more common for HVHZ-rated products.
• Coastal Construction Control Line (CCCL) — waterfront properties may need a separate CCCL permit.
• Historic districts (Miami Beach, Coral Gables, Coconut Grove) often require historic review to confirm profile, material, and grille pattern.
• Egress requirements — bedrooms need at least one egress window with minimum clear opening dimensions; enlarging or reducing an opening may trigger egress review.

Common mistakes that delay approval

Window permits are procedurally straightforward but still fail intake for predictable reasons.

• Filing without the manufacturer's current NOA attached to the application.
• Installing before the anchor and buck detail is field-verified.
• Choosing a window with an NOA that does not match the installation configuration (masonry vs. wood buck).
• Missing egress at bedroom windows.
• Not filing an electrical sub-permit when installing motorized shades or hurricane shutters at the same time.
• Historic district properties choosing a profile not approved by the historic preservation board.

Documents usually needed

Window permit applications are among the more predictable filings in Miami-Dade, and the document list rarely varies.

• Building permit application (Miami-Dade or municipal form).
• Elevation drawing showing the location of every window with sizes labeled.
• Product Approval / NOA sheets for each unit.
• Manufacturer's installation drawings, including anchor schedule.
• Buck detail (if a wood buck is used inside a masonry opening).
• Egress analysis for bedroom windows.
• Historic Preservation Board approval letter, when applicable.
• Contractor license and insurance on file.
