Miami-Dade Building Permits and Inspections Process

Miami-Dade County operates one of the most active building permit systems in Florida, processing tens of thousands of permit applications annually across a jurisdiction that encompasses 34 municipalities and an unincorporated area of more than 1,900 square miles. The permit and inspection framework governs construction, renovation, demolition, and mechanical system changes on residential and commercial properties. Understanding how this system works — which agency has authority, when permits are required, and what inspections must occur — is essential for property owners, contractors, and developers operating in the region.

Definition and scope

A building permit is a formal authorization issued by a government authority confirming that proposed construction or alteration work complies with applicable codes before work begins. In Miami-Dade County, the primary authority administering permits in unincorporated areas is the Miami-Dade Department of Regulatory and Economic Resources (RER) — Building and Permitting division. This department enforces the Florida Building Code (FBC), the Miami-Dade County Code, and locally adopted amendments that address South Florida's specific wind, flood, and hurricane resistance requirements.

Scope and coverage: RER's permitting jurisdiction applies to unincorporated Miami-Dade County. Properties located within the boundaries of incorporated municipalities — including the City of Miami, Miami Beach, Coral Gables, Hialeah, and 31 additional incorporated cities — fall under each municipality's own building department, not RER. A property owner in the City of Miami, for example, must apply through the City of Miami Building Department, which administers its own permit portal and inspection schedule while still enforcing the statewide Florida Building Code. This page does not address permitting processes for individual municipalities. For broader context on how Miami-Dade's departmental structure is organized, the Miami-Dade County Departments reference provides an institutional overview.

Work performed in coastal high-hazard areas or within Federal Emergency Management Agency (FEMA) Special Flood Hazard Areas carries additional review requirements tied to floodplain management regulations under 44 CFR Part 60, which Miami-Dade administers locally through its floodplain management ordinance.

How it works

The Miami-Dade permitting process follows a structured sequence from application submission to final certificate of completion.

  1. Application submission. Applicants submit permit applications through the Miami-Dade ePlan portal, which accepts electronic plan sets for most permit types. Applications must identify the contractor of record, property folio number, scope of work, and applicable product approvals for hurricane-impact materials.

  2. Plan review. RER reviewers assess submitted drawings against the Florida Building Code (FBC 8th Edition as of 2023), Miami-Dade's High Velocity Hurricane Zone (HVHZ) requirements, zoning compliance, and any applicable environmental regulations. Commercial projects above a threshold square footage require concurrent review by Miami-Dade Fire Rescue for life-safety compliance.

  3. Permit issuance. Once all review disciplines approve the application, the permit is issued electronically. Permit fees are calculated based on the valuation of construction; the fee schedule is published by RER and updated periodically.

  4. Inspections. Permitted work requires inspections at defined stages — typically foundation, framing, rough-in mechanical/electrical/plumbing, and final. Inspections are requested through the ePlan portal or by phone. An inspector visits the site and either approves the stage or issues a correction notice.

  5. Certificate of Completion or Occupancy. After all required inspections pass, RER issues a Certificate of Completion (for work that does not change the occupancy of a structure) or a Certificate of Occupancy (CO) for new buildings or occupancy changes. No new commercial space may legally be occupied without a valid CO.

Miami-Dade's HVHZ designation — one of only two such zones in the United States, covering all of Miami-Dade and Broward counties — imposes stricter product approval requirements than the standard Florida Building Code. All exterior windows, doors, and roofing products installed in the HVHZ must carry a Miami-Dade Notice of Acceptance (NOA) issued through RER's product approval section.

Common scenarios

Residential roof replacement. A permit is required for any full roof replacement in Miami-Dade. The contractor must pull a roofing permit, submit product approvals for the chosen roofing system, and schedule at least two inspections: a dry-in inspection before underlayment is covered and a final inspection upon completion.

Kitchen and bathroom remodels. Interior remodels that alter plumbing, electrical, or mechanical systems require trade permits in addition to a general building permit. A bathroom addition that moves a drain line, for example, requires a plumbing permit and rough-in inspection before walls are closed.

New construction (commercial). A commercial building permit in unincorporated Miami-Dade triggers review by building, zoning, environmental resources, and fire departments. The Miami-Dade Planning Department may also be involved if the project requires a development order or variance. Projects in designated flood zones require a floodplain development permit concurrently.

Unpermitted work. When unpermitted work is discovered — often during a property sale or insurance inspection — the property owner must apply for an after-the-fact permit. RER requires that unpermitted work be either exposed for inspection or demolished and rebuilt to current code standards. After-the-fact permits typically carry a double-fee penalty under the county's fee schedule.

Decision boundaries

The threshold question in every scenario is whether a permit is legally required. Miami-Dade's code distinguishes between work that is exempt, work requiring only a trade permit, and work requiring a full building permit with plan review.

Exempt work (no permit required) includes minor repairs such as painting, flooring replacement that does not affect structural elements, and cabinet replacement without moving plumbing or electrical. The Florida Building Code §105.2 enumerates general exemptions, but Miami-Dade's locally adopted amendments narrow some of those exemptions due to HVHZ requirements.

Trade permits only apply to isolated mechanical, electrical, or plumbing repairs that do not involve structural changes — for example, replacing a water heater of the same fuel type and capacity.

Full building permit with plan review is required for new structures, additions, structural alterations, changes of occupancy, and any work involving the building envelope in the HVHZ.

A second key boundary involves contractor licensing. Florida Statute §489.127 prohibits performing permitted work without a licensed contractor of record. Homeowners may pull an owner-builder permit for their primary residence, but they must personally supervise and perform the work — they may not use unlicensed labor as subcontractors. Licensed contractor verification can be confirmed through the Florida Department of Business and Professional Regulation (DBPR).

For residents and property owners seeking additional context on county governance structures that shape these regulatory functions, the Miami-Dade County Government resource provides institutional background.
