PERMIT GUIDE
Impact Window & Door Permit Guide for Miami-Dade County, Florida
Miami-Dade County is part of Florida's High Velocity Hurricane Zone (HVHZ), which requires the STRICTEST building code standards in the entire state. All impact windows and doors installed in Miami-Dade must carry a valid Miami-Dade NOA (Notice of Acceptance) — a unique certification that proves the product was tested under TAS 201, TAS 202, and TAS 203 protocols. This guide explains exactly how the permit process works across Miami-Dade and its major cities.

The Strictest Standard in the Country: Miami-Dade HVHZ Requirements
Miami-Dade County is part of Florida's High Velocity Hurricane Zone (HVHZ), which requires the STRICTEST building code standards in the entire state. All impact windows and doors installed in Miami-Dade must carry a valid Miami-Dade Notice of Acceptance (NOA) — a unique certification that proves the product was tested under TAS 201 (large missile impact), TAS 202 (cyclic wind pressure), and TAS 203 (uniform static pressure) protocols. These standards exceed Florida Building Code requirements anywhere else in the state.
Unlike other parts of Florida where Florida Product Approval (FPA) may suffice, Miami-Dade ONLY accepts products with a current, valid Miami-Dade NOA. There are no exceptions for residential, commercial, coastal, or inland properties. If the product's NOA is expired or does not cover the specific dimensions and installation conditions, the plan reviewer will reject the permit package.
Each NOA specifies the maximum product dimensions, design pressure ratings, installation substrate, and accepted fastening methods. The contractor must verify that the NOA covers the exact conditions of each opening before applying for the permit — not just that the product generally carries Miami-Dade approval.
How the Permit Process Works in Miami-Dade
Most incorporated cities within Miami-Dade County operate their own independent building departments. Miami, Coral Gables, Miami Beach, Hialeah, Doral, Homestead, and other cities each have their own permitting offices, online portals, and review staff. The Miami-Dade County Building Department only issues permits for properties in unincorporated county areas.
The process begins with the licensed contractor preparing the complete documentation package: permit application, site plan, window/door schedule with dimensions and design pressures, current Miami-Dade NOAs for each product, HVHZ design pressure calculations, and contractor license documentation. This package is submitted electronically through the applicable municipality's building portal.
After submission, an assigned plan reviewer verifies that the proposed products have valid Miami-Dade NOAs covering the specific installation conditions — including maximum dimensions, design pressure ratings, and installation substrate. If there are discrepancies or missing documentation, the reviewer issues correction requests. Once the permit is approved, installation can begin and the final inspection closes out the permit.
Timeline: How Long Does It Take?
Residential impact window and door permits in Miami-Dade County typically take 4 to 6 weeks from submission to approval. This is the longest processing time in our service area, primarily because Miami-Dade has the highest construction project volume in the region and the HVHZ review requirements are the most stringent in the country.
Timelines vary by municipality. The City of Miami, due to high application volume, can approach or exceed 6 weeks for standard projects. Miami Beach, especially for properties in the historic South Beach district, may require additional preservation review layers that add time. Doral tends to be more efficient for standard residential projects. Coral Gables has its own architectural standards review process.
The most common cause of avoidable delays in Miami-Dade is incomplete documentation or Miami-Dade NOAs that do not cover the exact installation conditions. A contractor experienced in Miami-Dade's various municipalities' requirements can significantly reduce the risk of correction requests and delays.
Required Documents
The following is the typical set of documents required for an impact window and door project in Miami-Dade County. Some municipalities may require additional documentation, but these cover the HVHZ standards applicable throughout the county.

- 10HOA approval letter (if applicable)
Permit Costs and Fees
Residential impact window and door permits in Miami-Dade County typically range from $150 to $500, depending on the project scope, the specific municipality, and the number of openings. Miami-Dade tends to have the highest permit fees in our service area, partly reflecting the building department's higher workload and the more demanding HVHZ review requirements.
Miami-Dade permit fees are typically calculated based on contract value, number of openings, or a combination of both factors. In addition to the base permit fee, projects may be subject to technology surcharges, plan review fees, and inspection fees. Some municipalities charge separate fees for structural plan review versus building plan review.
Your licensed contractor can provide an accurate permit fee estimate once the project scope and applicable municipality are defined. Fees vary between cities, so we always verify current municipal fee schedules before submitting the permit package.
HOA & Special Requirements in Miami-Dade
Miami-Dade County has a high concentration of active HOA communities, particularly in planned residential areas of Doral, Kendall, Pinecrest, and Palmetto Bay. In these communities, HOA approval must generally be obtained BEFORE submitting the permit application. The HOA process typically adds 1 to 3 additional weeks.
The correct sequence for HOA properties is: first prepare full project documentation (product specifications, frame colors, glass type, exterior installation details) and submit to the HOA for review. Once the HOA approval letter is received, it is included in the permit application package. Reversing this order can result in significant delays or the need to correct completed work.
Condominiums in Miami-Dade — particularly in Brickell, Edgewater, and the Miami Beach area — may have board approval processes that sometimes run in parallel with the permitting process. A contractor with experience in Miami-Dade communities can help you plan and manage both processes efficiently.
Inspections: What to Expect
Once installation is complete, a final inspection by the applicable municipality is required to close out the permit. The Miami-Dade inspector verifies that windows and doors are installed strictly per the approved permit documents — including that the Miami-Dade NOAs cover the specific conditions of each opening, that fastening methods are compliant, and that exterior and interior sealants are completed.
Since Miami-Dade is in the HVHZ, inspectors are particularly rigorous about NOA compliance. An NOA that does not cover the exact opening dimensions, or that specifies a different fastening method than what was used, can result in a failed inspection requiring additional work before final approval can be obtained.
After a passed inspection, you may obtain a wind mitigation certificate documenting your property's wind protection. This certificate can be submitted to your homeowners insurance carrier to request substantial hurricane coverage discounts. Since Miami-Dade is in the HVHZ, the available discounts can be the highest in the state.
City-Specific Considerations
Miami Beach
Miami Beach operates its own building department with additional requirements for properties in historic districts, particularly in South Beach (Miami Beach Historic Preservation District). Properties in these areas may require approval from the Miami Beach Historic Preservation Board before obtaining a permit, which can add 4 to 6 weeks to the timeline. Properties east of Collins Avenue are subject to coastal construction zone restrictions. For projects outside historic zones, Miami Beach follows the standard HVHZ process.
Coral Gables
Coral Gables is known for its strict Mediterranean architectural standards and color palette restrictions governing exterior modifications. The Coral Gables building department may require additional review from the Architectural Review Board for windows and doors that are street-facing. Coral Gables homeowners should plan ahead for architectural approvals, which can add 2 to 4 weeks to the timeline before permit submission.
Pinecrest
Pinecrest is a separate municipality with its own permitting process administered by the Village of Pinecrest, not Miami-Dade County. While it follows the same HVHZ product requirements, the Village's review process can add 1 to 2 additional weeks compared to unincorporated county areas. The Village of Pinecrest building department is generally efficient, but application volume may affect timelines during busy construction seasons.
Key Biscayne
Key Biscayne operates as a separate Village and is subject to additional coastal construction zone restrictions, given its island location. Properties in Key Biscayne may require additional reviews for exterior openings under Florida's coastal construction zone regulations. Oceanfront condominiums in Key Biscayne may have additional corrosion-resistance requirements for hardware. Plan ahead for potential additional coastal review time.
Homestead
Homestead has its own building department and generally offers a more efficient permitting process than central Miami or coastal municipalities. There are fewer additional review layers for most standard residential properties. However, Homestead is still HVHZ and requires Miami-Dade NOA on all products. Homestead communities with active HOAs must follow the standard HOA approval process before permit submission.
Doral
Doral is a modern city with a generally well-organized and efficient building department. For standard residential projects, Doral's permitting process tends to be faster than the City of Miami or historic municipalities. Many of Doral's residential communities have active HOAs, particularly in its planned neighborhoods — HOA approval must be obtained before permit submission. Doral's process is primarily online.
