Windows & Doors Permits, Codes & Inspections in FL: What You Need to Know

Windows & Doors Permits, Codes & Inspections in FL: What You Need to Know

If you bought a home in Miami in the last 15 years, there is a measurable chance the previous owner replaced windows or doors without pulling a permit. That unpermitted work is now legally your problem. It can stall a refinance, kill a sale at the closing table, and in the worst case, give your insurance company a reason to deny a hurricane claim. This guide walks through exactly what Florida building code requires, what Miami-Dade County specifically demands beyond the state baseline, who is responsible for the paperwork, and what it costs to fix if the permit was skipped on a previous owner’s watch.

Quick Answer

Window and door replacement in Florida requires a building permit when the opening size changes, when structural headers are touched, or when you create a new opening. Direct same-size replacements are often exempt under Florida Building Code 105.2, but Miami-Dade County requires product approval documentation (NOA or FL approval numbers) for any window or door installed in a wind-borne debris region, which includes all of Miami. A homeowner who skips permits risks insurance claim denial and a title cloud that typically costs $1,500 to $4,000 to resolve later, versus $150 to $500 to permit correctly upfront.

When a Building Permit Is Required vs. Exempt

Florida Building Code Section 105.2 draws a line between “direct replacement” and “alteration.” A direct replacement means you are swapping a window or door for a new unit with the same rough opening dimensions, no header changes, and no structural modification. In many Florida municipalities, that work is exempt from a building permit. But the exemption has teeth: if the new unit is larger, if you are widening an opening, if you are cutting a new opening where one did not exist, or if the lintel or header above the opening needs modification, a permit is mandatory.

Here is the practical breakdown we see in Miami-Dade County:

• Same-size window or door swap, no structural change: Usually exempt from a building permit, but the product still must carry a valid Miami-Dade or Florida product approval.
• Widening an opening, even by 4 inches: Permit required. The header is load-bearing; you are altering structure.
• Creating a new opening in a concrete block or masonry wall: Permit required, plus structural engineering drawings, plus a lintel detail.
• Converting a window into a door or a solid wall into a sliding glass door: Permit required. This changes egress, structural load path, and wind load calculations.
• Impact window installation where none existed: Even if same-size, Miami-Dade product approval docs are mandatory to verify the unit is legal for your wind zone.

In our experience, homeowners in neighborhoods like Coral Gables, Pinecrest, and Kendall get tripped up by the same-size exemption, often missing the warning signs covered in our Windows & Doors Warning Signs: A Miami Homeowner’s Reference Guide. They assume “no permit needed” means “no paperwork needed.” But Miami-Dade is a High Velocity Hurricane Zone (HVHZ). Every window and door installed here must be on the county’s product approval list, and the installer must keep that approval on file. No permit does not mean no code compliance.

Miami-Dade Documentation Requirements: NOA Numbers and Product Approvals

Miami-Dade County operates its own product approval system, separate from the statewide Florida Building Commission system. A window, door, shutter, or skylight installed in Miami-Dade must carry either a Miami-Dade NOA (Notice of Acceptance) or a Florida Product Approval (FL number). This is not optional paperwork. Without it, the unit is not legal to install in the county, period.

What you need before installation:

1. The NOA or FL product approval sheet. This is a multi-page document that lists the exact make, model, size limits, pressure ratings, and installation methods the product is approved for. It is not the same as a warranty card or a brochure.
2. The product approval number matching the exact unit being installed. A CGI model approved for a 60×60 window may not be approved for a 96×60 window. The approval has size and design pressure limits.
3. The installation instructions referenced in the approval. Miami-Dade inspectors often check that the anchoring method (tapping screws, anchor spacing, f-channel or receptor systems) matches what the NOA specifies.
4. Signed Notice of Acceptance forms for impact products where applicable. If the product is impact-rated, the approval will include missile impact test results (large and small missile).

We work with eight professional product lines including PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. Each carries product approvals for Miami-Dade. When we provide a written quote, we include the specific product approval numbers for the exact sizes and models proposed. That way the homeowner is not guessing whether the unit is legal.

Homeowners who buy windows direct from a big-box store often learn the hard way: the box store sells the window, but does not verify the NOA matches the opening. We have been called to Miami homes where brand-new windows had to be removed and replaced because the product did not meet Miami-Dade wind load requirements for that elevation. The cheapest window is often the most expensive mistake in this county.

Florida Building Code Section 1609: Wind Loads and Your Wind Zone

Florida Building Code Section 1609 governs wind loads, and Miami-Dade sits in the most demanding zone in the state: the High Velocity Hurricane Zone, with a design wind speed of 170 to 180 mph depending on the exact location and building risk category. That is higher than Broward, higher than Palm Beach, and dramatically higher than most of the rest of the country. The number determines what products are even legal on your house.

In plain terms, a window rated for 150 mph is not legal in Miami-Dade on a single-family home. The county requires products tested and approved for the design pressure (DP) rating that matches your home’s exposure category. Exposure matters too:

• Exposure B: Homes surrounded by buildings, trees, or terrain that breaks the wind. Lower pressure demands.
• Exposure C: Homes on open water, in flat terrain, or with direct wind fetch. Higher pressure demands.
• Exposure D: Direct oceanfront. Highest pressure demands, and the most restrictive product list.

A home in West Miami may sit in Exposure B, while a condo in Brickell or a house in Coconut Grove facing the bay sits in Exposure C or D. The same window that works for one house is not legal on the other. This is why a one-size-fits-all big-box approach fails in Miami: the product selection has to match the exposure category, the elevation, and the exact wind zone, as detailed in The Complete Guide to Windows & Doors in Miami.

Low-E glass (a thin coating that blocks heat while letting light through) is a coating choice. Impact resistance is a structural rating. These are separate issues. A window can be low-E but not impact-rated, or the reverse. In Miami-Dade, if you are replacing windows on any elevation facing the wind, impact rating or an approved shutter system is mandatory under the HVHZ provisions.

If you need a Window Repair in Miami rather than a full replacement, the permitting and product approval rules differ: repairing a sash, replacing glass, or fixing hardware does not trigger the same documentation requirements as replacing the entire unit. See our repair page for details.

Who Pulls the Permit: Homeowner vs. Contractor Responsibility

Florida law allows a homeowner to pull an owner-builder permit on their own residence. That is legal, and in a small set of circumstances it is fine, though we cover the trade-offs thoroughly in our DIY vs Professional Windows & Doors: The Miami Homeowner’s Decision Guide. But there is a catch most people do not realize until an inspection fails: when a homeowner pulls the permit, the homeowner is legally responsible for the work meeting code, even if a contractor performed the labor. The liability sits with the permit holder.

Here is how responsibility breaks down in practice:

• Owner-builder permit: The homeowner signs the permit application, takes on the code responsibility, and is the party the inspector will call if something fails. If a contractor does the work under an owner-builder permit and then disappears, the homeowner owns the problem.
• Contractor-pulled permit: The licensed contractor’s name and license number are on the permit. The contractor is legally obligated to correct failed inspections, close the permit, and stand behind the work. This is the correct path for replacement work that touches structure or product approvals.
• Lapsed permit: If a permit is open for too long without an inspection, the county can let it lapse. Reopening a lapsed permit requires new fees, possible re-inspection, and in some cases new product approvals if the code has changed since the original application.

We tell every Miami homeowner the same thing: if the scope involves a structural header, a new opening, or impact-rated products, the contractor should pull the permit under their license. That is the only way the legal responsibility for code compliance transfers off the homeowner and onto the party who actually performed the work.

Rough Inspections vs. Final Inspections: What Each Covers and What Fails

Window and door replacement in Miami-Dade typically involves two inspection milestones: the rough inspection and the final inspection. They are not the same thing, and skipping either one leaves the permit open and the work legally incomplete.

Rough Inspection:

This happens after the old unit is removed and the new unit is installed but before trim, stucco, drywall, or any finish material covers the anchoring. The inspector is looking at:

• Anchoring method, spacing, and fastener type against the NOA installation drawings
• Flashing and sealing at the perimeter: head, sill, jamb
• Shim placement and gap consistency
• Header condition where framing or masonry was modified
• Mullion installation where multiple units are joined

What fails a rough inspection in Miami-Dade, based on what we see in the field:

• Anchors installed farther apart than the NOA specifies. This is the single most common failure. The product approval might call for anchors every 18 inches, and the install crew ran them every 24 inches because that is what they do in other states.
• Foam-only sealing at the perimeter without mechanical anchoring. Foam is insulation, not structure.
• Wrong fastener type: drywall screws in a concrete block opening instead of Tapcon or sleeve anchors.
• Missing or inadequate flashing, especially at the sill in stucco walls, which leads to water intrusion that shows up years later.

Final Inspection:

The final inspection occurs after finish work is done. The inspector verifies the installation is complete, the permit can close, and the work matches what was approved. Common issues: the installed unit is a different model than what was listed on the permit application, the impact label is missing or painted over, or the permit is for a single window and the inspector finds three replaced.

In our experience, the rough inspection is where bad installs surface, and the final inspection is where missing paperwork surfaces. Miami-Dade inspectors know their NOA library. They will check model numbers against the approval sheet, especially for impact products from CWS, ES Windows, and ECO Window Systems.

Unpermitted Work: How It Appears in a Title Search and What Permit Close-Out Costs

Unpermitted window and door work in Miami typically surfaces during a title search when a home is sold or refinanced. Title companies compare county permit records against the physical condition of the house. If the house has impact windows or newer doors but the county records show no permits pulled since construction, a red flag goes up. That red flag can stall closing, trigger a demand for a permit close-out, or in some cases cause the lender to refuse financing until the issue is resolved.

What happens next depends on the scope of the unpermitted work:

• Same-size replacements with no structural change: Miami-Dade offers a “permit close-out” or “after-the-fact permit” process in some cases. The work is inspected, product approvals are verified, and if everything passes, a certificate is issued. Cost typically runs $500 to $1,500 depending on the number of openings and inspection fees.
• New openings or structural modifications without a permit: This is more serious. The county may require engineering plans, destructive inspection to expose anchoring and headers, and in some cases removal and re-installation by a licensed contractor. Cost commonly runs $1,500 to $4,000 or more, and can delay a sale by weeks.
• Unpermitted work that fails inspection: If the county finds non-compliant products or anchoring, those units may have to be replaced entirely before the permit can close. That cost is the full replacement cost, not a fix-it fee.

Doing it right the first time, with a permit pulled before work starts, costs $150 to $500 in permit fees in Miami-Dade for a typical window or door replacement scope. The after-the-fact route costs three to ten times as much and carries the stress of a deadline. We have walked through this process with Miami homeowners selling homes in neighborhoods like Shenandoah and Kendall, where unpermitted work from previous owners surfaced at the worst possible moment.

If you are buying a Miami home and want to check the permit status of visible window or door work, the Miami-Dade County Building Department maintains a public permit search portal. Enter the address, review the permit history, and compare it against what you can see. If the windows look new and there is no permit on file, that is a negotiation point before you sign, not after.

What Permits Cost in Miami-Dade and What You Should Budget

Permit fees in Miami-Dade are set by the county and depend on the valuation of the work. For a typical single-family window replacement project of 8 to 12 windows, the building permit fee generally runs $150 to $400. Door replacements run toward the lower end. Larger scopes, structural changes, or new openings push the fee up proportionally with the declared valuation.

Here is a realistic budget range for a Miami homeowner:

Any contractor who quotes a window or door replacement in Miami without mentioning permits should make you pause. If they tell you permits are not needed for a structural change, run. If they tell you the homeowner should pull the permit to save money, they are shifting legal liability onto you. Neither is a company you want inside your home.

We put the price in writing before anyone picks up a tool, on every job, no exceptions. That written price includes the permit fees when a permit is required. The homeowner sees the full cost before the first window is removed. There is no change order after the fact, and no surprise line item on the final invoice.

Common Mistakes to Avoid

• Assuming same-size replacement means zero paperwork in Miami-Dade. You still need product approvals on file. The permit may be exempt, but the code compliance is not.
• Buying windows online or from a big-box store without checking the NOA. A unit that is legal in Jacksonville or Tampa may not be legal here. If the model is not on the Miami-Dade approval list, it cannot be installed, period.
• Letting a general contractor who rarely does windows handle a Miami-Dade impact installation. Anchoring and flashing in an HVHZ are different from standard residential work. We see failed rough inspections from crews unfamiliar with NOA installation drawings all the time.
• Pulling an owner-builder permit and hiring a crew off the street. You are now the responsible party. If the work fails inspection or leaks after a storm, that is on you, even if someone else did the labor.
• Skipping the permit on a structural change to save $300. The after-the-fact close-out or replacement cost will eat that savings ten times over, and a title issue can hold up a sale for weeks.
• Painting over or removing the impact label from new windows. Inspectors and insurance auditors check those labels. If it is gone, proving the product is impact-rated becomes your problem.
• Assuming the insurance company will not notice. After a hurricane claim, insurers check permit records. Unpermitted or non-compliant work is one of the most common reasons for claim denial in South Florida.

When to Call a Professional

If your Miami home has unpermitted window or door work from a previous owner, or if you are planning a replacement that involves structural changes, a professional who knows Miami-Dade’s permit process is not a luxury. It is the difference between a smooth close-out and a stalled sale. The same applies if you are buying a home and the title search flags window work with no permit record: you need someone who can assess what was done, verify product approvals, and quote a fix if needed.

Frequently Asked Questions

The Bottom Line

Permits are not bureaucracy. In Miami, they are the paper trail that protects your insurance claim, your title, and your legal standing after a storm. The right sequence is simple: verify the product is approved for your wind zone, pull the permit when structure is touched, pass the rough inspection with proper anchoring, and close the final inspection with documentation intact. Skip any step and the cost compounds, often surfacing at the worst possible time. If you are buying, selling, or replacing windows and doors in Miami, start by checking the permit record. Then call someone who knows the county’s rules cold.

Front Door Replacement in Miami carries its own set of Miami-Dade product approval and wind load requirements, especially for impact-rated doors. We cover those specifics on our dedicated page.
