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

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

Here is a number most Orlando homeowners never see until it is too late: after Hurricane Ian, county building departments across Central Florida reported that roughly one in three window and door installations they audited had no permit on file. That is not a paperwork technicality. Florida courts have sided with insurers who denied hurricane damage claims because unpermitted window installations voided the home’s structural integrity warranty, a clause buried in standard homeowner’s insurance policies that most residents never read. This guide explains exactly what triggers a permit requirement in Orange, Osceola, and Seminole counties, what inspectors look for after Ian, and how to protect your insurance claim, your home sale, and your family before the next storm makes landfall.

Quick Answer

In nearly every jurisdiction across Florida, including Orlando, replacing windows or exterior doors requires a building permit, even when the new unit is the same size as the old one. The Florida Building Code’s “like-for-like” exemption is narrower than most homeowners assume, and Orange, Osceola, and Seminole counties each enforce the threshold differently. Skipping the permit risks insurance claim denial after a storm, a defect disclosure obligation when you sell, and a 4-point inspection failure at renewal time.

What Actually Triggers a Window or Door Permit in Florida

The short answer: almost everything. Florida Building Code Section 105.1 requires a permit for any work that alters the building’s exterior envelope, and windows and doors are the most heavily regulated components of that envelope. The code does carve out a narrow “minor repair” exemption for things like replacing a broken pane of glass or swapping out a lock set, but the moment you remove the frame, pull the rough opening, or change the structural connection between the unit and the wall, the permit requirement kicks in.

The confusion starts with the phrase “like-for-like.” Homeowners reasonably assume that if the new window is the same size as the old window, no permit is needed. That assumption is wrong in most Orange County jurisdictions. Here is what the code actually says, in plain English:

• Glass-only replacement: Replacing glass within an existing frame generally does not require a permit. This is a repair, not an installation.
• Sash replacement: Replacing a sash (the moving part of the window) within the original frame may fall under the minor repair exemption, but only if the frame itself is untouched. Pull the frame and you have crossed the line.
• Full window or door replacement: Removing the old unit down to the rough opening and installing a new one, even the exact same dimensions, requires a permit in the vast majority of Florida jurisdictions, including Orlando, Winter Park, Kissimmee, and Sanford.
• Size change or opening alteration: Enlarging a window opening, converting a window to a door, or replacing a sliding door with French doors always requires a permit and typically requires a structural review of the header.
• Impact-rated upgrades: Adding hurricane-resistant windows or doors is specifically flagged in Florida Building Code as work that requires permit review, because the product must be verified against a specific wind zone and design pressure rating.

In our experience, the most common permit surprise in Orlando comes from the sliding glass door. Homeowners treat an old sliding glass door as a “repair item” and replace it without thinking, only to find out at the next 4-point inspection that the insurance carrier requires the permit number and the wind-load documentation. We have seen this exact scenario play out in the Dr. Phillips and Conway neighborhoods more times than we can count.

Orange, Osceola, and Seminole: How the Big Three Compare

All three counties follow the Florida Building Code, but each jurisdiction applies administrative rules differently. What passes in one county’s online permitting portal may be rejected in the next county over. If you are planning a window or door project in the Orlando metro area, here is what to expect in each jurisdiction where we work most often.

Orange County: The unincorporated county and most of its cities, including Orlando proper, require a permit for full window and door replacement. Orlando’s Building Division has been aggressive about post-Ian enforcement, and inspectors now cross-check product approval numbers against the FL Building Code database at final inspection. Expect to submit a product approval specification sheet for every window line you install. Orange County also requires a separate floodplain review if your home is in a FEMA flood zone, which adds a few days to the review timeline. Homes in Thornton Park, College Park, and Baldwin Park fall under the City of Orlando’s jurisdiction specifically, while Windermere and Winter Garden have their own building departments, both of which follow the same base code but with stricter homeowner documentation requirements for owner-builder permits.

Osceola County: Kissimmee and St. Cloud take a slightly different approach. Osceola generally requires permits for window and door replacement, but the county has a streamlined “express permit” path for like-for-like replacements under a certain square footage that does not require a full plan review. That does not mean you can skip the permit, it means the permit review happens faster, often same-day or next-day. The catch is that Osceola inspectors are known to be strict on flashing details at final inspection, so the installation workmanship matters. We recommend homeowners in Kissimmee ask their installer specifically about the self-adhered flashing product they plan to use before signing anything.

Seminole County: Sanford, Lake Mary, and Longwood follow a permit-always approach for window and door replacement, with no express path. Seminole also has a unique requirement that caught many homeowners off guard after Ian: the county requires a signed and sealed engineering letter for any window or door job where the opening size changes by more than two inches in any direction, even if the header is untouched. That is stricter than most surrounding jurisdictions, so budget a few extra hundred dollars and a few extra days if your project in Seminole involves resizing.

One note that applies everywhere: unincorporated county areas and city limits can cover different rules within the same zip code. A home on the edge of Apopka might actually fall under Orange County’s jurisdiction, not the City of Apopka’s. Check the property appraiser’s website for your jurisdiction before you start.

The Inspection Process: Rough-In vs. Final, and What Inspectors Look For After Ian

Once your permit is issued and the old window is out, you enter the inspection phase. In Florida, window and door replacement typically requires two inspections: the rough-in and the final. Understanding what happens at each stage helps you spot an installer who is cutting corners before the inspector finds out.

Rough-In Inspection: This happens after the old unit is removed and the new unit is set in the opening, but before any trim, caulk, or interior finish work covers the flange and the rough opening. The inspector is looking for three things:

• Nail fin or flange connection: The inspector verifies that the window or door is anchored to the framing per the manufacturer’s installation instructions. Spacing on fasteners matters, and the inspector will check it against the spec sheet for the specific brand you installed, whether that is PGT, CGI, or any other line.
• Flashing sequence: This is where most failed inspections happen. Florida code requires a specific overlap sequence for the self-adhered flashing at the sill, jamb, and head. If the flashing layers are installed in the wrong order, water gets behind the flange and into the wall cavity. Post-Ian, Orange County inspectors specifically check the sill flashing detail on every window, regardless of product brand.
• Product approval labels: Every window and door installed in Florida must carry a permanent label showing the product approval number and the design pressure rating. The inspector records this number. We have seen inspectors fail a rough-in because the installer tore off the label during installation, which means the product approval cannot be verified at final.

Final Inspection: This happens after the job is complete, including finish trim and caulk. The inspector verifies the finished condition, confirms the product approval numbers match what was submitted at permit, and checks that the installation matches the permit scope. If the job passes, the inspector signs off and the permit is closed. A closed permit is the document your insurance company wants to see after a storm claim.

Here is the sequence in numbered form, so you know what a proper window installation looks like in Orlando:

1. Permit is issued and posted on the job site.
2. Old window is removed and the rough opening is cleaned and inspected for rot or damage.
3. New window is set, anchored, and flashed according to the manufacturer’s installation instructions.
4. Rough-in inspection is called in and passed.
5. Trim, caulk, and interior finish work is completed.
6. Final inspection is called in and passed, and the permit is closed.

A closed permit is the only proof that the work was done legally. An open permit on your property records can cloud a title when you sell. We recommend keeping the closed permit number with your closing documents from any window or door project at your Orlando home.

Notice of Commencement: The Document That Protects You From a Mechanic’s Lien

A Notice of Commencement (NOC) is a one-page document recorded with the county that establishes the legal start date of your project and creates a public record of who is doing the work. Florida law requires an NOC for any permitted job where the contract price exceeds $2,500, which includes most window and door replacement projects in the Orlando market. The document is filed with the county clerk before work begins, and the permit number is tied to it.

Why does this matter to you as a homeowner? The NOC is your protection against a mechanic’s lien. Without an NOC on file, a subcontractor or material supplier who is not paid by the general contractor can place a lien on your home even if you paid the contractor in full. That is not a hypothetical. We have heard from Orlando homeowners who discovered a lien from a glass supplier months after paying a contractor for a full-house window job, because no NOC was filed and the supplier had no legal trigger to release their claim. Once an NOC is recorded, all parties have a deadline to file a lien notice within 45 days of the NOC expiration or the work ending, and after that window closes, the lien right expires.

The sequence matters: the NOC must be recorded before the first day of work. If a contractor starts the job and then files the NOC afterward, any lien protection that was supposed to attach from day one is compromised. Reputable window and door companies in Orlando, including our team at Hale Windows Orlando home, handle the NOC filing as part of the permit management process. If a contractor tells you the NOC is not necessary for your job, treat that as a red flag, not a convenience.

HOA Approval vs. Building Permit: Why You Need Both and in What Order

Living in a planned community in Orlando means two separate approval processes for your windows and doors. The building permit is a legal requirement from the county or city. The HOA approval is a contractual requirement from your community association. Neither replaces the other, and getting the sequence wrong can cost you thousands in removal and redo work.

In communities like Baldwin Park, Winter Park’s tree-lined neighborhoods, Celebration, and most of the master-planned developments in Lake Nona, the HOA architectural review committee has specific rules about window styles, frame colors, glass tints, and even the permissible brand lines. Some HOAs require a specific aesthetic, such as bronze-framed impact windows on all street-facing elevations, while others restrict the use of reflective glass. If you install a window that violates the community’s architectural standards, the HOA can legally require you to remove it and replace it with a compliant unit at your own expense. That is an expensive mistake we have seen happen.

The correct order is HOA first, then permit, then installation:

1. Request the HOA architectural review application and submit your proposed window or door specifications, including product brand and finish color.
2. Wait for written HOA approval. Do not order product and do not pull the permit until you have this in hand.
3. Submit the permit application with the HOA approval attached, if the jurisdiction asks for it.
4. Schedule the installation after the permit is issued.
5. Keep both the HOA approval letter and the closed permit in your home records.

One nuance most homeowners miss: HOA rules can be stricter than the building code, but they cannot be looser. If the code requires impact-rated windows and your HOA wants a specific aesthetic that is only available in a non-impact product, the code wins. That is a conversation worth having with a window company that works with multiple product lines, because the right product match from brands like CGI, ES Windows, or ECO Window Systems can often satisfy both the code requirement and the HOA’s aesthetic standards.

Unpermitted Work on a 4-Point Inspection: What It Costs to Remediate

Here is the part most Orlando homeowners discover too late. A 4-point inspection is a document Florida insurance carriers require for homes older than 20 years before they will write or renew a policy. The inspector evaluates four systems: roof, electrical, plumbing, and HVAC. Windows and doors are typically covered under the roof or structural section of that report, and insurance companies increasingly ask specifically about impact protection and permit history on the window openings.

When a 4-point inspector finds windows that were replaced without a permit, the inspector has no choice but to list the work as “unpermitted” or “unable to verify.” That single line changes your insurance picture. The carrier may require you to obtain a retroactive permit before they bind the policy, which involves opening the wall, pulling back the trim, and paying an inspector to verify the installation was done correctly, plus paying a double permit fee and possible code enforcement fees. The process often costs more than the original installation, and the insurance clock is running while you scramble.

We have seen remediation costs for unpermitted window work in Orange County run anywhere from $1,200 to $4,000 depending on how many openings need verification and whether the installer’s work actually passes inspection once it is exposed. Some homeowners end up replacing the windows a second time because the first installer used an unapproved product that cannot pass retroactive inspection, regardless of workmanship.

There is also the resale problem. Florida law requires sellers to disclose all known defects and unpermitted work on the seller’s disclosure statement. If you sell a home with unpermitted window replacements and fail to disclose them, you create a legal exposure that can follow you for years after the closing. Buyers’ lenders increasingly review permit history before funding, and title companies flag open permits or permit-work discrepancies during due diligence. The cleanest way to protect a sale is to have a closed permit for every window and door project, which is why window replacement in Orlando should always begin with the permit conversation, not the product conversation.

Product Matters: Impact-Rated Windows, Design Pressure, and Miami-Dade Approvals

Not every window that fits your opening is legal to install in Orlando. The Florida Building Code divides the state into wind-borne debris regions and assigns design pressure requirements to each zone. Orlando sits inland, outside the most severe coastal wind zone, but the code still requires windows and doors in newly installed openings to meet specific wind load ratings and, in many cases, impact resistance standards. The product number stamped on the frame tells the inspector whether the unit is approved for your specific wind zone.

The term you will see on inspection reports is “design pressure” (DP), which measures how much wind force the window or door can withstand before structural failure. A higher DP rating means a stronger product, and the required number varies by opening size and exposure. A picture window on a protected wall has a lower requirement than a sliding glass door on a west-facing elevation that catches afternoon thunderstorms. The product approval label must match or exceed the required DP for that specific opening. If it does not, the inspector fails the rough-in and the window has to come out.

Impact-rated windows, often called “hurricane windows” even inland, are built with laminated glass that holds together when struck by flying debris. In coastal counties they are mandatory for new construction. In Orlando they are not mandated for most single-family homes outside flood zones, but many insurance carriers offer premium discounts for impact-rated products. That is why product selection and permit compliance are the same conversation: a CWS impact window or a PGT WinGuard unit installed with a closed permit gives your insurance carrier documentation they can use to apply hurricane mitigation credits to your policy. An unpermitted installation of an impact product achieves nothing, because the carrier has no verified record that the window actually meets code.

The right product match also matters for the inspection process itself. Each brand line has its own installation instructions and approval documentation, and the inspector verifies against that specific document. A window installer who works with multiple professional-grade lines, from ECO Window Systems to ES Windows, can match the product to the wind load requirement, the HOA aesthetic, and the budget, with the paperwork ready for the inspector. A one-brand installer often tries to force a product into an opening it was never designed to pass inspection for.

Common Mistakes to Avoid

• Assuming “like-for-like” means “no permit.” In Orange, Osceola, and Seminole counties, full window and door replacement requires a permit even when the size is unchanged. The only true exemptions are glass-only and sash-only repairs that leave the frame untouched.
• Skipping the HOA review because the permit is approved. The HOA process is separate and sequential. Installing windows that violate the community’s architectural standards can force a costly removal and redo, even if the county signed off.
• Not filing a Notice of Commencement. For any permitted job over $2,500, the NOC is your only legal protection against a mechanic’s lien from an unpaid subcontractor or supplier. It costs a small county recording fee and must be filed before work starts.
• Hiring an installer who says you do not need a permit. That statement is either ignorance or evasion. Either way, the liability lands on the homeowner, not the installer, when the insurance claim is denied or the home sale collapses.
• Ignoring the product approval label. If the label is removed or the installed product does not match the permit application, the inspector will fail the job. The window gets pulled, the drywall gets patched, and the budget blows up.
• Letting a permit stay open after the job ends. An open permit shows up on title searches and can delay or derail a home sale. The final inspection and permit closure are part of completing the job correctly.
• Assuming impact windows are required everywhere in Orlando. They are not required for most inland single-family homes, but insurance discounts often make them worth considering. The product decision should follow the code requirement and the HOA standards, not a sales pitch.

When to Call a Professional

If any of these situations describe your project, call a licensed window and door specialist before you start pulling trim or signing anything: you are replacing more than two windows or doors at once, your home is in an HOA with architectural rules, you are upgrading to impact-rated products for insurance credits, you discovered the previous owner’s windows were unpermitted, or your insurer asked for a 4-point inspection and flagged the window openings. In each of these scenarios, the permit, the product, and the installation quality are linked, and a mistake in any one of them creates a problem in the other two.

The Bottom Line

The permit conversation in Orlando is not bureaucracy for its own sake. It is the mechanism that keeps your insurance claim valid after the next storm, keeps your home sale clean when you decide to move, and keeps an inspector’s signature on the record that says the work was done right. Every window and door project should start with three questions: what does the code require for this specific opening, what does the HOA require for this specific elevation, and what product approval documentation does the inspector need to close the permit. Answer those three correctly and the rest of the project follows. Front door replacement in Orlando carries the same permit and inspection requirements as windows, and the same insurance implications. If you are not sure where your project falls, call (850) 613-9382 and describe what you are planning. We will tell you exactly what the process looks like for your specific house, in your specific jurisdiction, before you spend a dollar. And if a window repair is all you actually need, window repair in Orlando may be the simpler and more cost-effective permit-exempt path.
