You can sell a Melbourne, FL flood zone house as-is; the City's 50 percent rule governs repairs, not the sale.
Florida requires a flood disclosure at or before the contract, covering flood damage, claims, and FEMA or other help during your ownership (Fla. Stat. 689.302). FEMA has also issued a preliminary flood map for Brevard County, with a 90-day appeal period before it takes effect.

Has your Melbourne house flooded while you have owned it?
Free. No obligation. You choose the closing date.
To sell a house in a flood zone in Melbourne, FL, three rules shape the sale: the City's 50 percent rule, a preliminary Brevard County flood map, and Florida's flood disclosure form. None of them stops a sale. Each one changes what a buyer will ask about, and what you hand over at the contract.
This guide walks through the City of Melbourne, Florida floodplain code, the preliminary flood map for Brevard, and the exact questions on the state form. It sticks to what the official sources say, without guessing what the final map or any future storm will bring.
What is the Melbourne 50 percent rule?
The Melbourne 50 percent rule says that repair or improvement work costing 50 percent or more of a building's market value, measured before the work starts, is a "substantial improvement." It sits in the City's floodplain management code (Appendix D, Chapter 13, Article IX), in the definitions at Sec. 13.152.
The definition covers any "repair, reconstruction, rehabilitation, addition, or other improvement." The test is whether its cost "equals or exceeds 50 percent of the market value of the building or structure before the improvement or repair is started." Crossing that line brings the flood-resistant construction rules into the project.
Substantial damage works differently
The same section defines "substantial damage" as damage of any origin where restoring the building to its before-damaged condition would cost 50 percent or more of its market value. The definition does not require a flood; any cause counts.
Once a building has that label, the code is blunt. "If the structure has incurred 'substantial damage,' any repairs are considered substantial improvement regardless of the actual repair work performed." A small fix on a substantially damaged house falls under the same rules as a full rebuild.
A note on counting periods: the definitions quoted here measure a project's cost against the building's market value before the work starts. They do not mention a 12-month or multi-year total. If you have done several repairs over time, the City's floodplain administrator can confirm how your permits are counted.
How does the City measure a repair against the 50 percent line?
Melbourne's floodplain administrator sets the market value and compares it with the cost of the work when a permit is filed. Under City Code Sec. 13.154, the administrator will "Estimate the market value, or require the applicant to obtain an appraisal," then weigh the repair cost against that figure.
If the work reaches the line, the administrator notifies the applicant "that compliance with the flood-resistant construction requirements of the Florida Building Code and this floodplain management code is required." That notice is the moment a repair plan can grow into a much larger project.
For a seller, this review matters in two ways:
- A buyer who plans to renovate will face the same comparison when they pull permits.
- An open permit or a written substantial damage notice is part of the house's record, and buyers may ask about both.
Our guide to selling a Melbourne house with a City code lien covers open cases and permits in more detail.
What does the preliminary Brevard County flood map mean for a seller?
FEMA has issued a preliminary Flood Insurance Rate Map for Brevard County and Incorporated Areas, and it is not final yet. The City's Flood Hazard Information page lists what could change. The proposed determinations "may include the addition or modification of Base Flood Elevations, base flood depths, Special Flood Hazard Area boundaries or zone designations, or the regulatory floodway."
The City's page says there is a statutory 90-day period for appeals before the determinations take effect. It also says "Technical information or comments are solicited on the proposed flood hazard determinations." The page does not print the dates of that window, so this guide does not either.
Checking your own address
The City points residents to two FEMA resources for questions about the new map:
- The FEMA Flood Map Service Center, FEMA's official flood map site.
- The FEMA Map Information eXchange (FMIX), toll free at 1-877-FEMA MAP (1-877-336-2627).
Nobody can say yet how the final map will treat a given street. A preliminary map can still change through the appeal and comment process, so it helps to read it as a proposal, not a verdict.
Is the house inside Melbourne city limits?
Not always, because a Melbourne mailing address does not prove the house is inside the City. The City's Flood Prevention page says, "Even if you have a Melbourne address, you may live in what is called Unincorporated Brevard County (meaning outside of city limits)."
That matters for the 50 percent rule. Sec. 13.152 and Sec. 13.154 are City of Melbourne code. A house in unincorporated Brevard County answers to the county's floodplain rules and permitting office instead, so it can help to confirm which government issues permits for the address.
What does the Florida flood disclosure form ask a seller?
The Florida flood disclosure form asks three yes-or-no questions: flood damage during your ownership, flood insurance claims, and flood assistance. It applies to sales of residential real property statewide, Melbourne included.
"A seller must complete and provide a flood disclosure to a purchaser of residential real property at or before the time the sales contract is executed."
Fla. Stat. § 689.302, Florida Statutes
The three questions, word for word
The statute prints the form itself (Fla. Stat. § 689.302). Each line gives the seller a box to check:
- "Seller has ... has no ... knowledge of any flooding that has damaged the property during Seller's ownership of the property."
- "Seller has ... has not ... filed a claim with an insurance provider relating to flood damage on the property, including, but not limited to, a claim with the National Flood Insurance Program."
- "Seller has ... has not ... received assistance for flood damage to the property, including, but not limited to, assistance from the Federal Emergency Management Agency."
The form's definition of flooding is broad. It covers the overflow of inland or tidal waters, rapid runoff from a source such as a river, stream, or drainage ditch, and "Sustained periods of standing water resulting from rainfall." Rain that sits on a lot can count, not only rising tidal waters.
Two limits are worth seeing. The damage question covers flooding during your ownership only. None of the three asks which flood zone the house sits in.
What changes for a Melbourne seller by flood situation?
What a Melbourne seller faces depends on the house's flood history and its permit record. The table below sets four common situations against the City Code and the state disclosure form.
| Situation | City floodplain code (Secs. 13.152, 13.154) | Flood disclosure (Fla. Stat. 689.302) |
|---|---|---|
| No flood history | The 50 percent test comes up only if work costing 50 percent or more of pre-repair market value is permitted | Still required at or before the contract; the boxes read "has no" and "has not" |
| Flooded, repaired below the 50 percent line | Work under 50 percent of market value is not a substantial improvement by definition | Damage during your ownership, any flood claim (NFIP included), and any assistance (FEMA included) are disclosed |
| Substantial damage notice | Any repair counts as a substantial improvement; the administrator notifies that flood-resistant construction compliance is required | Same three questions; the damage that led to the notice is disclosed if it was flooding |
| Zone change on the preliminary map | Proposed changes may include Base Flood Elevations and zone designations; a 90-day appeal period comes before they take effect | The form does not ask about flood zones; its questions cover damage, claims, and assistance |
If the house sits in unincorporated Brevard County, the middle column comes from the county's rules, not the City's. The disclosure column applies either way.
Should you repair a Melbourne flood zone house before selling, or sell as-is?
Sellers in Melbourne generally choose between finishing repairs, listing the house in its current condition, or selling as-is for cash. The right path depends on the size of the repair, where it falls against the 50 percent line, and how much time and money you can put in.
| Path | When it can fit | What still applies |
|---|---|---|
| Repair first | The work is modest and stays under the 50 percent line | A permit review under Sec. 13.154; flood-resistant construction if the work reaches the line |
| List with an agent | The house is in good shape and time allows | The flood disclosure at or before the contract, plus any repair records a buyer asks for |
| Sell as-is | The repair would cross the line, or you would rather not take it on | The flood disclosure at or before the contract; the repair decision moves to the buyer |
Repairing first
Repairs below the line can make sense when the work is modest and the record is clean. Once a project reaches the line, Sec. 13.154 brings in flood-resistant construction requirements, and the job gets larger. It can help to get a written repair estimate first, so there is a number to set against the market value.
Listing with an agent
Listing can suit a house in good shape when time allows. A buyer will see the disclosure at or before the contract and may ask for repair records. Questions about premiums are covered in our guide to selling during Florida's insurance crisis.
Selling as-is
An as-is sale moves the repair decision to the buyer. You still complete the flood disclosure, since the statute applies to the sale itself. As-is means as-is: you are not asked to fix the floors, take on flood-resistant construction work, or settle the permit question first. Our page on selling a house that needs major repairs lays out how that works.
About elevation certificates: the state form does not require one. Under Fla. Stat. § 472.0366, a surveyor and mapper who completes a certificate must send a digital copy to the Florida Division of Emergency Management within 30 days. That rule began January 1, 2023.

Frequently Asked Questions
Do I still give a flood disclosure if my Melbourne house never flooded?
Yes. Fla. Stat. 689.302 requires a seller of residential real property to complete and provide the flood disclosure at or before the time the sales contract is executed. The statute makes no exception for houses that stayed dry. The form gives a "has no" box for the damage question and "has not" boxes for the claim and assistance questions.
Who decides whether a Melbourne house is substantially damaged?
Under Melbourne City Code Sec. 13.154, the floodplain administrator reviews the permit application. The administrator estimates the market value or requires the applicant to obtain an appraisal, compares it with the cost of the work, and notifies the applicant when flood-resistant construction compliance is required.
Does a substantial damage finding stop me from selling?
Nothing in Fla. Stat. 689.302 or the City's floodplain definitions bars a sale. The definitions in Sec. 13.152 describe repair and improvement work, and a sale by itself is neither. The flood disclosure still applies, and a buyer who later repairs the house works with the City's floodplain rules.
Where can I see the preliminary flood map for a Melbourne address?
The City's Flood Hazard Information page points to the FEMA Flood Map Service Center and to FEMA's Map Information eXchange, toll free at 1-877-336-2627. The same page refers to a statutory 90-day appeal period before the proposed determinations take effect.
Does FEMA disaster help count on the Florida flood disclosure?
Yes. Question 3 of the form in Fla. Stat. 689.302 asks whether the seller has received assistance for flood damage to the house, "including, but not limited to, assistance from the Federal Emergency Management Agency." Question 2 separately asks about insurance claims, including a claim with the National Flood Insurance Program.
Do I need an elevation certificate to sell in Melbourne?
The flood disclosure form in Fla. Stat. 689.302 does not ask for one. If a certificate was completed on or after January 1, 2023, Fla. Stat. 472.0366 required the surveyor and mapper to send a digital copy to the Florida Division of Emergency Management, so an existing one may already be on file there.
