Do You Need a Permit to Replace Windows in Melbourne, Florida?

Yes. In the City of Melbourne, replacing windows generally needs a building permit, and the Building Section's FAQ lists window replacement among the projects that require one. Exterior doors, including sliders, are generally permitted the same way, but confirm with the Building Section. Your installer usually applies through the city's EnerGov online system and uploads a Florida product approval for each unit. The one possible way around it is Florida's 2026 exemption for some single-family work under $7,500, which in Melbourne you must request in writing and have approved before any work starts.

Quick answers by project

First, make sure Melbourne is your permit office

A Melbourne mailing address doesn't mean the City of Melbourne issues your permit. Postal names don't always match city limits, and communities such as Viera and Suntree aren't cities. Brevard County issues building permits only for unincorporated areas; inside city or town limits, the city or town does.

If you're not sure which side of a city line you're on, ask the city or the county before anyone applies. Our Brevard County permit guide covers each office's filing system in more detail.

What a Melbourne window permit involves

We couldn't find Melbourne's current window and door checklist. A January 2021 city guide to EnerGov submittals asked, for window and door alterations, for one PDF per product (a Florida product approval or a Miami-Dade Notice of Acceptance, each uploaded separately) and a sketch showing where each replacement goes. That guide is several years old, so ask the Building Section, or check its forms page, for the current list. Brevard County and West Melbourne ask for similar items: product approvals and a drawing or floor plan of the openings.

A product approval for every unit

Each window and door must carry a Florida product approval (an "FL number") or a Miami-Dade Notice of Acceptance (NOA). Brevard isn't in the High-Velocity Hurricane Zone, which is only Miami-Dade and Broward, so a Miami-Dade NOA isn't required. The approval lists the sizes tested, the design pressures, whether the unit is impact-rated and how it must be installed, and the inspector checks the installation against it.

Look up each FL number on the Florida Building Commission's product approval search before you sign. The 9th Edition of the Florida Building Code takes effect December 31, 2026, according to the Commission's work plan. If your application will go in near that date, ask your installer which edition it falls under and whether the products quoted are approved under it. Our product approval guide explains how approvals work.

Design pressure, and impact glass where required

The permit reviewer looks at two separate ratings. Every unit needs a design pressure rating at least as high as its opening requires, whether or not it's impact glass. If your home is in the wind-borne debris region, glass openings must also be impact-resistant or covered by approved impact protection, such as shutters.

Under the 2023 Florida Building Code, the region covers areas within one mile of the coast where an Exposure D condition (open water upwind) exists and the design wind speed is 130 mph or more, plus anywhere the design wind speed is 140 mph or more, so distance from the ocean alone doesn't settle it. We couldn't confirm which Melbourne-area addresses are inside, so ask the Building Section about yours before you compare quotes; Brevard County's wind speed maps show an address's design wind speed. Our Brevard impact window cost guide explains both ratings, and impact windows vs. hurricane shutters compares the two ways to protect openings.

Bedroom escape windows

Bedroom windows usually double as emergency escape openings. In the model residential code that Florida's code is based on, an escape opening needs at least 5.7 sq. ft. of net clear opening (5 sq. ft. for a grade-floor opening), at least 24 inches of clear height and 20 inches of clear width, and a sill no more than 44 inches above the floor.

Florida's rules for existing buildings give replacement windows some relief. As described in Florida Building Commission code documents, a replacement bedroom window doesn't have to meet the full size and sill-height rules if it's the manufacturer's largest standard size that fits the existing frame or rough opening, and it's either the same operating style as the old window or a style with an equal or larger opening. The relief doesn't apply to a change of occupancy. Confirm the current wording with the Building Section, and don't let an installer swap a bedroom's opening window for a fixed picture window or a style with a smaller opening.

Bucks and changed openings

In a concrete-block home, a window is often anchored to a buck, a frame fastened inside the masonry opening. A rotted or damaged buck needs repair before the new unit can be anchored to it. West Melbourne requires a buck affidavit at the final inspection, so ask whether Melbourne expects anything similar.

Making an opening bigger, or turning a window into a door, is structural work. Expect structural details, possibly engineering, and a new header or lintel in a block wall. It also rules out the $7,500 exemption.

Notice of Commencement, inspections and fees

Notice of Commencement. Florida law requires a certified copy of the recorded Notice of Commencement, or a notarized statement that it has been filed for recording, before the first inspection when the direct contract is more than $5,000. At our Florida planning range of $900 or more per standard impact window, six windows already pass that mark (6 × $900 = $5,400). It's signed before a notary and recorded with the Brevard County Clerk of Courts; see the Notice of Commencement.

Inspections. Melbourne schedules inspections through EnerGov; see the city's inspections page and ask which ones your permit needs. The job isn't done until the final inspection passes and the permit is closed, so hold back the final payment until then. See building inspections in Florida.

Fees. Melbourne sets its fees in a building permit fee schedule effective August 7, 2026; check it before you budget, and ask the Building Section about current review times. In unincorporated Brevard, the county's doors, windows and shutters page lists a $25 application processing fee plus a code review fee of $75 for the first $1,000 of job value and $3.25 for each additional $1,000. Confirm current fees with the office that covers your address.

Who pulls the permit

In most window jobs, the licensed installer applies, uploads the product approvals and drawings, and schedules the inspections. Before you sign, get in writing who files the permit and who records the Notice of Commencement, and ask for the permit number once it's issued.

Florida also lets you pull the permit yourself as an owner-builder, for a home you own and will live in, if you supervise the work. Melbourne publishes an owner-builder guide. You take on a contractor's legal responsibilities, so read owner-builder permits in Florida first. A contractor who asks you to pull an owner-builder permit for work they're doing is a red flag.

Melbourne's $7,500 exemption request

Florida's 2026 permit law, HB 803, took effect July 1, 2026. It bars local governments from requiring a building permit for some work valued under $7,500 on a single-family home, if the owner or contractor asks in writing. Melbourne has published how it handles those requests.

How to apply in Melbourne:

• Create the request like a permit application in EnerGov, using the "Exemption Request" application type.
• Include the property and owner information, a notarized request form, and a copy of the signed contract between you and the contractor. If you're doing the work yourself, include documentation of its value.
• Pay the review fee. The city's August 7, 2026 fee schedule appears to list it at $62.50; confirm the amount with the Building Section.
• Don't start work until the city approves the request in writing. If it's denied, the fee you paid goes toward a building permit for the same work.

Who qualifies: a single-family home outside a designated flood hazard area, with work valued under $7,500. Electrical, plumbing, mechanical, gas and structural work still need a permit at any value, and the law bars splitting a bigger job into smaller ones to stay under the limit.

What it means for windows. We found nothing from the city on whether a window or door swap counts as structural, so ask before you count on the exemption. The dollar limit also narrows it to small jobs. As an illustrative estimate at our Florida planning range of $900–$1,800 per installed standard impact window:

• Three windows: 3 × $900 to 3 × $1,800, or about $2,700–$5,400. Under the limit either way.
• Four windows: about $3,600–$7,200. Under the limit even at the top of the range.
• Eight windows: about $7,200–$14,500. Under the limit only at the bottom of the range.

These are planning estimates, not quotes. Real prices depend on sizes, products and the condition of each opening, and the exemption goes by the contract's value.

Check your flood zone first. You can view flood zones on Brevard County's interactive flood map, but ask the city to confirm whether your lot is in a designated flood hazard area before you file.

Even when a small job qualifies, a permit can be worth having. Exempt work gets no plan review or inspection, and a finaled permit is part of the record a wind mitigation inspector, an insurer or a buyer may want to see. Our guide to the $7,500 exemption covers the statewide rules.

HOA approval is a separate step

If your neighborhood has a homeowners' association, you'll usually need its architectural approval as well as the city's permit. Florida law requires HOAs to adopt hurricane protection specifications and bars them from denying applications that meet them, and since July 1, 2026 an HOA can't require a building permit before it reviews your application. Get the specifications before you order. See HOA approval in Florida.

What happens if you skip the permit

Fees, delays and removal. Melbourne warns that starting work without a permit can lead to much higher costs, delays and even removal of what was built. In Palm Bay, work started without a permit can be charged up to four times the permit fees. Fixing it later means applying for the permit after the fact and showing the installation meets the approval.

Insurance credits. Florida law (section 627.0629) requires insurers' rate filings to include credits or discounts for features that reduce wind losses, including opening protection. Wind mitigation inspectors record those features on the state's form, revised in April 2026, and rely on documentation such as permit dates and product approval numbers. Without a finaled permit and approvals, the inspector may not be able to credit the new windows. No credit is guaranteed either way, so ask your agent what your carrier requires. See wind mitigation inspections.

Selling later. A buyer or their insurer may ask for permit records, and an unpermitted or never-finaled job may have to be permitted after the fact while a sale is pending.

Common mistakes

• Going by the mailing address. Confirm whether Melbourne, another city or Brevard County issues your permit.
• Starting work while an exemption request is pending. Melbourne says to wait for written approval.
• Assuming impact glass covers everything. Each unit also needs a design pressure rating that meets its opening's requirement.
• Ordering windows before checking approvals. Look up each FL number and its listed design pressures first.
• Shrinking a bedroom's escape opening by changing window style.
• Skipping the Notice of Commencement on a job over $5,000, or paying in full before the final inspection.
• Letting a contractor talk you into an owner-builder permit for work they're doing.

Next steps

1. Confirm which office covers your address, and check whether your lot is in a flood hazard area.
2. If you have an HOA, get its hurricane protection specifications.
3. Ask each installer for a written quote that lists, for each opening, the product approval number, the required and rated design pressure and whether it's impact-rated, plus who pulls the permit.
4. Check each installer's license with the state and on Brevard County's Licensed Contractor Search.
5. Track the permit in EnerGov and keep the final inspection record with the product approvals.
6. Book a wind mitigation inspection after the permit closes, and send the report to your insurance agent.
