Do I Need a Permit to Remodel My House in Miami-Dade?

When a permit is usually required

House remodels are the most permit-intensive residential project type. The specific combination of permits depends on the scope, but nearly every substantive remodel involves multiple filings.

• Structural work — removing walls, adding beams, altering roof structure, additions.
• Electrical — new outlets, circuits, panel changes, generator installation.
• Plumbing — moving fixtures, adding bathrooms or laundry, water heater relocation.
• Mechanical — HVAC replacement, ductwork changes, exhaust ventilation.
• Roof replacement or repairs above a certain area threshold.
• Window and door replacements on the exterior envelope.
• Additions, garage conversions, ADU conversions.
• Deck, patio, or pool work.

When a permit may not be required

A narrow list of cosmetic work is often permit-exempt in Miami-Dade, though condo associations and HOAs may still require internal approval.

• Painting interior and exterior.
• Flooring replacement that does not affect subfloor.
• Wallpapering.
• Cabinet refacing without electrical or plumbing changes.
• Trim, base, and moulding installation.
• Interior door replacement using existing frames.

Miami-Dade / South Florida considerations

House remodels in Miami-Dade routinely involve multiple review layers — local building department, historic preservation, coastal review, and condo association approvals.

• Master permit + trade sub-permits — most substantive remodels require a master building permit with separate plumbing, electrical, and mechanical sub-permits, each filed by an appropriately licensed contractor.
• Historic districts — Miami Beach, Coral Gables, Coconut Grove, and Miami Shores often require historic preservation review for exterior work and sometimes for interior floor plan changes to landmarked properties.
• Coastal Construction Control Line (CCCL) — waterfront properties may need a separate CCCL permit for anything seaward of the coastal line.
• 40-year and 50-year recertification — older buildings in Miami-Dade require periodic structural and electrical recertification; remodel timing can interact with this.
• Condo associations — high-rise remodels almost always require association approval, riser diagrams, and often a certificate of insurance from a licensed contractor.
• Board of Architects — Coral Gables projects visible from the exterior often require Board of Architects review.

Common mistakes that delay approval

The mistakes that delay house remodel permits are almost always coordination failures rather than plan-review disagreements.

• Starting demolition before permits are issued.
• Missing sub-permits behind the master permit — the CO cannot issue until every sub-permit is closed.
• Contractor license mismatched to the scope of work.
• Historic district review skipped or filed late.
• CCCL review overlooked on waterfront properties.
• Condo association approval not secured before city intake.
• Product Approval missing for windows, doors, or roofing.

Documents usually needed

House remodel filings often involve a substantial package of documents. The exact list depends on scope but typically includes the following.

• Master building permit application.
• Plumbing, electrical, and mechanical sub-permit applications.
• Sealed architectural and structural drawings for structural changes.
• Electrical single-line diagram for panel work.
• Plumbing riser and fixture plan.
• Mechanical drawings for HVAC changes.
• Product Approval for windows, doors, and roofing.
• Notice of Commencement for projects above the county threshold.
• Historic Preservation Board approval, when applicable.
• Condo or HOA approval, when applicable.
• Contractor licenses, insurance, and workers' comp on file.
