Do I Need a Permit for Window Replacement in Fort Lauderdale, FL?

Window replacement in Fort Lauderdale is unlike window replacement almost anywhere else in the country. Broward County's HVHZ designation means all glazing must be impact-rated — no exceptions. Every window installed in Fort Lauderdale must have Florida Product Approval or Miami-Dade NOA documentation confirming HVHZ compliance. And unlike most of the country, Fort Lauderdale requires a building permit for window replacement regardless of whether the opening is being modified.

The Short Answer

YES — window replacement in Fort Lauderdale requires a building permit and HVHZ-rated impact windows.

The HVHZ provisions of the Florida Building Code require that ALL glazing in Broward County be impact-rated (or protected by approved shutters). Window replacement in Fort Lauderdale requires a building permit from DSD through LauderBuild, and the replacement windows must have valid Florida Product Approval (FPA) with HVHZ designation or Miami-Dade NOA. The permit documents the FPA numbers for all windows being installed. Florida-licensed contractor (CBC/CGC/CRC or appropriate specialty license) required. Contact DSD at 954-828-6520.

HVHZ Impact Glazing Is Mandatory: The FBC states "ALL glazing in HVHZ requires impact rating or approved shutters — no exceptions." Non-impact windows without approved shutters cannot be legally installed in Fort Lauderdale under any circumstances, regardless of whether the opening is being modified or the work is being treated as a repair. This is fundamentally different from most of the country where standard non-impact windows can be used. Verify the FPA number and HVHZ designation for every proposed window product before signing any contract.

Fort Lauderdale window replacement permit rules — the HVHZ reality

Window replacement in Fort Lauderdale requires a building permit and HVHZ-compliant windows for every installation — there is no "same opening, no structural modification" exemption that applies in most of the country. The HVHZ requirement that all glazing be impact-rated (or protected by approved shutters) makes window replacement a code-governed activity in Fort Lauderdale regardless of whether the rough framing is being modified. The building permit documents the Florida Product Approval numbers for all windows being installed, and the building inspector verifies that the installed windows match the approved products and are properly anchored to the rough opening per the FPA installation instructions.

All permits are applied for digitally through the LauderBuild portal at fortlauderdale.gov/lauderbuild — no paper applications are accepted. The permit application requires the FPA or NOA numbers for every window product in the project, the window schedule (sizes, types, locations), and the completed Broward County Uniform Permit Application. Florida State-licensed contractors (CBC, CGC, CRC, or a Florida-licensed specialty contractor) pull the permit. Walk-thru applications for qualifying simple scopes are processed 8:00–9:30 AM Monday–Friday the next business day.

Florida Product Approval verification is essential before purchasing any windows for a Fort Lauderdale project. FPA status can change — approvals expire, get revoked, or have conditions. Verify current FPA status for any proposed window product at the Florida Building Commission's product approval search at floridabuilding.org. Miami-Dade NOA status can be verified at miamidade.gov/building. Always verify immediately before purchase — an approved product at the time of quoting may have expired FPA by the time of installation.

Three Fort Lauderdale window replacement scenarios

Scenario A

Full-House Impact Window Upgrade (Same Openings)

A homeowner in a 1970s Fort Lauderdale home replaces all 16 original single-pane jalousie or aluminum slider windows with new impact-rated double-pane windows in the same openings. A building permit is required. The permit package includes the FPA numbers for the chosen impact window system, the window schedule (location and dimensions of all 16 windows), and the Broward County Uniform Permit Application. Impact windows are sized to fit the existing rough openings — the Florida-licensed contractor measures each opening and orders custom-sized impact window units. The building inspector verifies that the installed windows have proper FPA documentation and that the anchoring (screws into the rough framing at the FPA-specified locations and spacing) matches the product's installation requirements. Impact windows eliminate the need for separate hurricane shutters, eliminating the seasonal shutter installation and removal burden that many Fort Lauderdale homeowners have traditionally faced. Total project: $15,000–$40,000 depending on window count and product selection. Permit fee confirmed at 954-828-6520.

Building permit required | FPA documentation for all windows | Inspector verifies anchoring pattern | Eliminates hurricane shutters | Confirm fee: 954-828-6520

Scenario B

Window Enlargement for View or Natural Light (HVHZ Structural Modification)

A homeowner in Las Olas Isles enlarges a bedroom window from 36"x48" to 60"x60" to improve natural light and ventilation. The enlarged opening requires modifying the existing CBS rough framing — cutting through block, installing a new lintel (the structural element spanning the top of the window opening in CBS construction), and framing the new opening dimensions. The new larger window must be an HVHZ impact-rated product with FPA documentation. A building permit is required, with structural plans showing the lintel specifications for the enlarged opening in CBS construction. The Florida PE who stamps the lintel design must be familiar with CBS block construction — the lintel in a CBS wall is a different structural element than the header in wood-frame construction. Total project for one enlarged window: $4,000–$9,000 including structural work, CBS repair, stucco, and impact window. Permit fee confirmed at 954-828-6520.

Building permit required | FL PE lintel design for CBS opening | HVHZ impact window with FPA | CBS stucco repair required | Confirm fee: 954-828-6520

Scenario C

Accordion Shutter Installation (Alternative to Impact Windows)

A Fort Lauderdale homeowner chooses to retain their existing non-impact windows but install accordion shutters over all openings — an HVHZ-approved alternative to impact windows for hurricane protection. Accordion shutters must have Florida Product Approval for HVHZ and must be anchored to the structure per the product's FPA installation requirements. A building permit is required for accordion shutter installation. The permit documents the FPA numbers for the shutter system and the attachment hardware. Accordion shutters are widely used in Fort Lauderdale's condo buildings and single-family homes — they fold flat against the wall when not in use and can be deployed quickly when a hurricane threatens. They do not provide the continuous glass breakage protection that impact windows provide, but they meet the HVHZ protection requirement as an approved alternative. Total project: $8,000–$20,000 for a full-house accordion shutter installation. Permit fee confirmed at 954-828-6520.

Building permit required | HVHZ-approved FPA shutter system | Proper structural anchoring required | Alternative to impact windows | Confirm fee: 954-828-6520

Window/Opening Scope	Permit Required?	HVHZ Requirement
Same-opening impact window replacement	Yes — building permit	FPA/NOA documentation; anchoring per FPA
Enlarged opening	Yes — building permit + FL PE lintel	CBS lintel design; HVHZ impact window
Accordion shutters (over existing windows)	Yes — building permit	HVHZ-approved FPA; structural anchoring
Non-impact window installation	Yes — but PROHIBITED without shutters	Non-impact window cannot be installed without HVHZ shutters

Impact window selection for Fort Lauderdale

The Fort Lauderdale impact window market is mature and competitive — dozens of manufacturers offer HVHZ-compliant impact window products, and there are many established local installers familiar with Broward County permit requirements. The key selection criteria for Fort Lauderdale impact windows are: HVHZ compliance (Florida Product Approval or Miami-Dade NOA required), design pressure (DP) rating appropriate for the home's location within Broward County, energy performance (impact windows are inherently better thermal insulators than single-pane glass due to the laminated glass construction), and frame material durability in South Florida's salt-air environment.

Design pressure (DP) ratings quantify a window's resistance to wind load. For Fort Lauderdale's residential properties, the required DP depends on the window's position in the building (lower floors vs. higher, corner vs. field location) and the exposure category. The FPA documents the maximum approved DP for each product — the window installer calculates the required DP for each opening based on the FBC's wind load provisions and confirms the product's FPA covers that DP. Buyers should request the specific DP rating and FPA number for every window in a proposal, not just a general "impact-rated" assurance.

Frame material choices in Fort Lauderdale are primarily aluminum and vinyl. Aluminum impact frames dominate the commercial and premium residential market — aluminum is dimensionally stable, structurally strong, and available in a wide range of powder-coated colors. Vinyl impact frames are popular for residential applications and offer good thermal performance; vinyl frames expand slightly in high temperatures, which can affect hardware operation in large windows in South Florida's heat. Both materials are available with HVHZ product approvals from multiple manufacturers.

What Fort Lauderdale impact window replacement costs

Impact window replacement costs in Fort Lauderdale are higher than standard window replacement in most markets, reflecting the HVHZ product requirements, the South Florida labor premium, and the permit documentation requirements. Standard aluminum frame impact double-pane windows: $600–$1,200 per window installed (standard residential sizes). Premium vinyl frame impact windows: $700–$1,400 per window. Large format or custom sizes: $1,200–$3,500+ per window. Full-house replacement (16 windows, standard sizes): $12,000–$22,000. Accordion shutters (full-house): $8,000–$20,000. Permit fees confirmed at 954-828-6520.

Common questions

Does window replacement in Fort Lauderdale require a permit?

Yes. All window replacement in Fort Lauderdale requires a building permit from DSD through LauderBuild (fortlauderdale.gov/lauderbuild). Unlike most of the country where same-opening window replacement is a maintenance activity, HVHZ requirements in Broward County require the permit to document the Florida Product Approval numbers for all installed windows and verify HVHZ compliance. Contact DSD at 954-828-6520 for current permit fees.

Are impact windows required in Fort Lauderdale?

Yes, or approved hurricane shutters must be provided. The FBC states that all glazing in the HVHZ (which includes all of Broward County) must be impact-rated or protected by approved shutters — no exceptions. Non-impact windows without approved shutters cannot be legally installed in Fort Lauderdale under any circumstances. All impact windows must have valid Florida Product Approval (FPA) with HVHZ designation or Miami-Dade NOA. Verify FPA status at floridabuilding.org before purchasing any windows for a Fort Lauderdale project.

What is Florida Product Approval and how do I verify it?

Florida Product Approval (FPA) is a state certification that a window or door product meets Florida Building Code performance standards, including HVHZ standards for Broward County. Every impact window or shutter installed in Fort Lauderdale must have a valid FPA with HVHZ designation. Verify FPA status at the Florida Building Commission's online database at floridabuilding.org — search by manufacturer, product name, or approval number. Miami-Dade NOA is an alternative pathway; verify at miamidade.gov/building. Always verify immediately before purchase — FPAs can expire.

What is a Design Pressure (DP) rating and what do I need for Fort Lauderdale?

Design Pressure (DP) is a rating expressing the wind load a window can resist. Higher DP = better wind resistance. For Fort Lauderdale windows, the required DP depends on the window's position in the building and the FBC's wind load provisions for the specific location. The FPA for each window product specifies its maximum approved DP. Your window installer calculates the required DP for each opening and confirms the product's FPA covers that DP. Request the specific DP rating and FPA number for every window in a proposal, not just a general "HVHZ" or "impact" assurance.

What contractor license is required for window replacement in Fort Lauderdale?

Florida Building Contractor (CBC), General Contractor (CGC), or Residential Contractor (CRC) license, or a Florida-licensed specialty contractor appropriate for the window installation scope. As of September 1, 2025, per House Bill 735, non-licensed contractors may register for minor construction work through LauderBuild — contact DSD at 954-828-6520 to confirm whether window replacement qualifies. Verify any contractor's Florida license at myfloridalicense.com before hiring.

How do accordion shutters compare to impact windows in Fort Lauderdale?

Both accordion shutters and impact windows are HVHZ-compliant protection options in Fort Lauderdale. Impact windows: protect continuously without any action required before a storm; provide better thermal insulation and sound attenuation; allow natural light when shutters would be closed; typically add more home value. Accordion shutters: lower initial cost per opening; can protect existing non-impact windows (avoiding the cost of full window replacement); require deployment before a storm; fold flat when not in use. Both require building permits with FPA documentation. The choice depends on budget, convenience priorities, and home design preferences.
