Getting a building permit in Miami-Dade County is one of the most important and most misunderstood steps in any construction or renovation project. Skip it and you face code violations, fines, and potentially having to demolish work. Do it wrong and your project stalls for weeks in corrections. Here is a complete, straightforward guide to how the Miami-Dade building permit process works — and how to navigate it without losing your mind.
Do You Actually Need a Permit?
In Miami-Dade County, permits are required for virtually all construction work beyond minor cosmetic updates. You generally need a permit for any new construction, structural alterations or additions, roofing work, electrical work beyond simple fixture replacements, plumbing modifications, HVAC installations and replacements, window and door replacements (required to verify impact-resistant compliance), swimming pool installations, fence installations above certain heights, and garage conversions. If you are unsure whether your project requires a permit, call the building department for your specific municipality or contact a permit expeditor for a quick assessment.
Understanding Miami-Dade’s 34 Municipalities
This is the most important thing to understand before starting the permit process: Miami-Dade County contains 34 incorporated municipalities, each with its own building department. The City of Miami, Miami Beach, Coral Gables, Hialeah, Homestead, North Miami, North Miami Beach, Doral, Sweetwater, and more — each runs its own permitting process with its own portal, forms, fees, and review standards. Unincorporated Miami-Dade County (areas not within any city limits) is handled by the Miami-Dade County Building Department directly. Always confirm which jurisdiction your property falls under before submitting anything.
What Documents Do You Need?
The required documents vary by project type and municipality, but a typical residential renovation permit package in Miami-Dade includes a completed permit application, proof of contractor licensing and insurance, a site plan or survey showing property boundaries and the location of work, construction drawings or plans (may need to be sealed by an architect or engineer depending on scope), product approval documentation for windows, doors, and roofing materials (Florida Product Approval numbers), and the contractor’s workers’ compensation exemption or certificate of insurance.
For structural work, additions, and new construction, plans must be prepared and sealed by a Florida-licensed architect or structural engineer. The more complete and accurate your submission, the faster plan review proceeds and the fewer correction cycles you will face.
How to Submit Your Permit Application
Most Miami-Dade municipalities have moved to online permit submission through their respective portals. The City of Miami uses the iBuild Miami system. Miami-Dade County’s unincorporated areas use the DERM and Building Department portals. Miami Beach, Coral Gables, and other municipalities have their own systems. Some smaller municipalities still accept in-person or emailed submissions. Submitting to the wrong portal or in the wrong format is one of the most common causes of permit delays.
How Long Does Plan Review Take in Miami-Dade?
- Simple residential permits (no plans required): 1–5 business days
- Standard residential renovation (with plans): 2–4 weeks
- New residential construction: 4–8 weeks
- Commercial permits: 4–10 weeks
- After corrections are submitted: Additional 1–3 weeks per cycle
These are typical timelines — actual review times vary by department workload, time of year, and submission completeness. Incomplete submissions and correction cycles are the single biggest cause of permit delays, which is why getting the application right the first time is so valuable.
What Are the Permit Fees?
Miami-Dade permit fees are calculated based on the value of construction and the type of work. Residential permits typically range from a few hundred dollars for simple mechanical permits to several thousand dollars for new construction. Fee schedules are posted on each municipality’s building department website. Permit fees are paid at submission for online applications, or at the permit counter for in-person submissions.
Inspections — What to Expect
Once your permit is approved and work begins, you must schedule and pass required inspections at specific stages of construction. Common inspection stages include footings, framing, rough electrical, rough plumbing, rough mechanical, insulation, and final inspection. In Miami-Dade, inspections are scheduled through the building department’s online portal or phone system. Failing an inspection means the work must be corrected and re-inspected before proceeding — adding time and cost to your project. Work must not be covered or concealed before the required inspection is completed and approved.
How a Permit Expeditor Saves You Time and Money
A professional permit expeditor knows exactly what each Miami-Dade building department needs to see, how to submit it correctly, and how to follow up effectively when reviews are delayed. For most renovation and construction projects, the time and stress saved by hiring an expeditor far exceeds the cost of their fee.
