Building Permit Guide: Miami-Dade County (2026)
Miami-Dade is one of the most demanding permitting jurisdictions in the United States, and for good reason: the county sits in a High Velocity Hurricane Zone, much of it is low-lying, and its environmental agency reviews things most counties never look at. None of that is why projects get stuck, though. In our experience, the overwhelming majority of delays are not code failures. They are process mistakes made before the plans were ever submitted.
This guide walks the Miami-Dade building permit process from start to finish: who issues your permit, what you have to submit, who reviews it, how long it realistically takes, and what causes the delays nobody budgets for.
First question: who actually issues your permit?
This is the most common point of confusion, and getting it wrong costs weeks. Miami-Dade County contains 34 incorporated municipalities plus a large unincorporated area. Where your property falls determines who reviews your plans:
Unincorporated Miami-Dade. The county Department of Regulatory and Economic Resources (RER), Building Division, issues your permit. Applications and plans are filed through the county online submittal portal, and the office is the Herbert S. Saffir Permitting and Inspection Center at 11805 SW 26 Street, Miami.
Inside a municipality. Miami, Miami Beach, Hialeah, Coral Gables, Doral, Homestead, Aventura and the other cities each run their own building department, with their own forms, fees and review queues.
Here is the part that surprises people, including experienced contractors from other states: a municipal permit does not release you from county-level approvals. Even when your building permit is issued by a city, your project may still need sign-off from DERM (environmental), the Water and Sewer Department, Fire Rescue, the Department of Health, and impact fee assessment. Those are two tracks running at the same time, and the city will not issue until the county side clears.
Before anyone starts drawing, confirm jurisdiction using the property folio number. It takes ten minutes and it determines your entire submittal package.
What Miami-Dade will ask you to submit
The exact package depends on scope, but a typical application for new construction or a structural project includes:
Building permit application and contact sheet. County or municipal forms identifying owner, contractor and scope, prepared by the owner or contractor.
Signed and sealed plans. Digitally signed and sealed PDFs, prepared by the engineer or architect of record. A scanned image of a signature is not accepted.
Site plan. Setbacks, lot coverage, drainage, impervious area, utility connections and parking, prepared by the civil engineer.
Boundary and topographic survey. The current survey the site plan is built on, prepared by a licensed surveyor. Easements and elevations matter.
Structural calculations. Wind load calculations to HVHZ criteria and foundation design, prepared by the structural engineer.
Product approvals. Miami-Dade NOA or Florida Product Approval for windows, doors, shutters and roofing, supplied by the contractor or manufacturer.
Energy calculations. Florida Building Code energy compliance forms, prepared by the design professional.
Contractor license and insurance, or an owner-builder affidavit where permitted.
Two details cause more rejections than the rest combined. The first is the digital signature requirement: plans must carry a valid digital seal, not a scan. The second is consistency. The site plan, the survey and the architectural sheets must agree with one another on setbacks, dimensions and elevations, and reviewers check them against each other.
It is not one review. It is nine happening at once
When your application is accepted it does not go to a single plans examiner. It is routed simultaneously to every discipline and agency with jurisdiction over your scope:
Building, structural, electrical, mechanical, plumbing and roofing. The trade reviews.
Zoning. Setbacks, height, use, lot coverage and parking.
Fire Rescue. Access, hydrants, suppression and occupancy.
DERM. Drainage, septic and wells, tree removal, wetlands, contamination and stormwater.
Water and Sewer. Connection capacity and availability.
Public Works. Right-of-way, driveway connections, paving and swale drainage.
Department of Health. On-site sewage where there is no sewer connection.
Your permit moves at the speed of the slowest reviewer. A single unresolved DERM comment holds the entire package, no matter how clean the structural review was. This is why coordination between the civil engineer, the architect and the surveyor before submittal matters more here than in most jurisdictions.
How long does a Miami-Dade permit actually take?
The county states that initial plan review typically takes between 24 hours and 10 business days, and that rework reviews follow the same window once corrections are resubmitted.
That number is accurate and also misleading, because it describes one review cycle, not your project. What determines your real timeline is how many cycles you go through, and every round of corrections sends you back into the queue.
Trade permit such as an AC changeout or water heater: 0 to 1 review cycles, 1 to 2 weeks.
Interior residential remodel: 1 to 2 cycles, 4 to 8 weeks.
Addition or ADU: 2 to 3 cycles, 8 to 14 weeks.
New single-family home: 2 to 3 cycles, 3 to 5 months.
Commercial or multifamily site development: 3 or more cycles, 6 to 12 months.
These are typical ranges, not guarantees, and they assume a complete submittal. The lesson is not in the totals, it is in the cycles. Two avoidable correction rounds can add a month to a residential project and a quarter to a commercial one. Money spent on coordination before submittal buys back far more time than any expediting service.
The HVHZ factor
Miami-Dade and Broward make up Florida's High Velocity Hurricane Zone, and it changes what you are allowed to install. Products used in the HVHZ must carry either a Miami-Dade Notice of Acceptance (NOA) or an HVHZ-rated Florida Product Approval.
An NOA is issued by the county Product Control Section after testing that includes large missile impact, cyclic pressure loading and water resistance after impact. It applies to windows, doors, shutters, roofing assemblies and fasteners. There are three practical consequences for your permit:
NOA numbers must appear on the plans, and they must be current. Approvals expire.
A product approved for use elsewhere in Florida is not automatically acceptable in Miami-Dade.
A copy of the full NOA has to be available on site for the inspector.
Two ways to move faster
Private provider review
Florida law allows the owner to hire a licensed private provider to perform plan review and inspections instead of the building official. In Miami-Dade the building official then does not review the plans or perform the code inspections, subject to the county quality assurance program. It costs more up front and it can cut significant time out of the schedule on larger projects.
A complete first submittal
Less glamorous and more effective. Most of the delay in Miami-Dade is self-inflicted: incomplete packages, drawings that contradict the survey, expired product approvals, missing DERM items. A pre-submittal coordination pass between the civil engineer, architect, structural engineer and surveyor is the cheapest schedule insurance available.
One more thing for existing buildings: recertification
Miami-Dade requires building recertification at 30 years for inland buildings and 25 years for buildings within three miles of the coast, and every 10 years after that. Condominium and cooperative buildings three stories or taller also fall under Florida's milestone inspection requirements.
Recertification is not a building permit, but it routinely produces one. The inspection report identifies structural or electrical repairs, and those repairs require permits of their own. If you own or manage an aging building, this belongs in your capital planning, not in your emergency budget.
After the permit is issued
Issuance is the middle of the process, not the end. Inspections are performed Monday through Friday, 8:00 a.m. to 3:30 p.m., and are scheduled online or by phone. A typical vertical construction sequence runs foundation, framing, trade rough-ins, insulation and final, and each one has to pass before the next stage of work is covered up.
Permits also expire. If work stalls you need an extension before the permit lapses. Letting it die means reapplying, and sometimes re-reviewing under a newer code edition.
Frequently asked questions
How long does it take to get a building permit in Miami-Dade County?
The county reports initial plan review of 24 hours to 10 business days per cycle. End to end, a simple residential remodel commonly runs 4 to 8 weeks, a new single-family home 3 to 5 months, and a commercial site development project 6 to 12 months, depending on how many correction cycles the submittal generates.
Do I need a permit for a home remodel in Miami-Dade?
Almost certainly. Structural changes, electrical, plumbing, mechanical work, roofing, windows and doors all require permits. Cosmetic work such as painting or flooring generally does not. When in doubt, ask before the work starts, because retroactive permits cost far more than ordinary ones.
My property is inside a city. Do I still need county approval?
Often yes. The city issues the building permit, but county-level approvals from DERM, Water and Sewer, Fire Rescue, the Department of Health and impact fee assessment may still apply. Confirm both tracks at the start of the project.
Do my plans have to be signed by a licensed engineer?
For structural work, new construction, additions and site development, yes. Plans must be signed and sealed by a Florida-licensed engineer or architect, and the seal must be digital.
What is a Miami-Dade NOA?
A Notice of Acceptance is the county product approval confirming that a window, door, shutter or roofing assembly passed High Velocity Hurricane Zone testing. NOA numbers must be shown on the permit plans and the approval must be current at the time of installation.
What happens if I build without a permit in Miami-Dade?
Expect a stop-work order, fines that can accrue daily, a requirement to expose or remove completed work for inspection, and problems with insurance, financing and resale. Retroactive permitting is possible but slower and more expensive than permitting correctly the first time.
