Architectural / construction drawings including floor plan, elevations, cross-sections, and all dimensions.
Structural drawings with Florida PE (licensed Professional Engineer) seal — required for HVHZ decks over 200 sq ft or attached to the structure. Drawings must show footing design, post/column schedule, beam and joist sizes, and all connection hardware rated for HVHZ wind exposure.
Product approvals (Miami-Dade Notice of Acceptance or Florida Product Approval) for all wind-critical components: connectors, fasteners, and composite decking if used.

Timeline

Typical timing

Plan review: 10–20 business days for electronic plan review
Total cycle: 5–10 weeks from application to final inspection

Projects requiring product approval verification, special inspection, or correction rounds take longer. HVHZ structural review adds time compared to jurisdictions using base IRC.

Process

How the permit process works

Confirm HVHZ requirements before designing All of the City of Miami lies within Miami-Dade County's High Velocity Hurricane Zone. Every deck must be designed for 175 mph wind speeds, using HVHZ-rated connectors and hardware. Engage a licensed Florida structural engineer early — HVHZ sealed drawings are typically required.
Verify zoning and property restrictions Use the City of Miami GIS at gis.miamigov.com to confirm setbacks, zoning district, and any overlay designations. Miami's NRD (Neighborhood Revitalization District) and historic district overlays can impose additional restrictions.
Obtain product approvals for HVHZ materials All structural connectors, fasteners, lumber treatment, and composite decking must have a valid Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval. Your engineer will specify these products; verify the NOA is current at miamidade.gov/permits/product-approval.
Submit permit application through iBuild Register at the City of Miami iBuild portal, create a permit application, and upload all required drawings and documents. Miami currently processes most residential deck permits through electronic plan review.
Address plan review comments Plan reviewers check structural, zoning, HVHZ product approval, and FBC compliance. If comments are issued, your engineer revises the drawings and resubmits through iBuild.
Record Notice of Commencement and pay fees Before starting construction, record the NOC with Miami-Dade County Clerk of Courts and post a copy at the job site. Pay permit fees through the iBuild portal or in person at the Building Department.
Schedule inspections during construction Required inspections include: foundation/footing, framing/structure, HVHZ special inspection (if required), and final. Request inspections through the iBuild portal or by calling the Building Department inspection line.
Pass final inspection and close permit Once the final inspection is approved, the permit is finaled and the work is recorded. Keep the permit and inspection records — they are required for insurance and real estate transactions in Florida.

What can go wrong

Unpermitted construction in Miami-Dade is subject to stop-work orders and can trigger mandatory demolition if the structure cannot be retroactively permitted.
Florida homeowners insurance carriers routinely inspect for permits; HVHZ wind mitigation credits are only available for permitted, inspected work.
Unpermitted work discovered during a real estate transaction must be disclosed and can kill a sale or require immediate remediation.
HVHZ wind loads are severe — unpermitted decks without proper engineering and hardware inspection pose a genuine structural safety risk during hurricane events.
Miami-Dade County can place a lien on the property for outstanding code violations and unpermitted work.
