Fort Myers adds up 12 months of repairs; at 50% of the building's value, flood rules apply.
The City measures against the structure value alone, land excluded, and a building that crosses the line must be raised to or above the base flood elevation. Repair or sell, Florida requires a flood disclosure at or before the contract (Fla. Stat. 689.302).

Have you pulled a repair permit on your house in the last 12 months?
Free. No obligation. You choose the closing date.
The Fort Myers 50 percent rule decides whether a storm-damaged house can simply be repaired or must be brought up to flood rules first. In Fort Myers, Florida, the City adds up repairs and improvements made over a 12-month period. It compares that running total to the market value of the building alone, with the land left out.
Once the total reaches 50%, the City's own permit packet says the building "must be brought into compliance" with its flood rules, including raising it to or above the base flood elevation.
What is the Fort Myers 50 percent rule?
The Fort Myers 50 percent rule is the City's test for substantial damage and substantial improvement. If repairs, or repairs plus improvements within 12 months, cost 50% or more of the building's pre-work market value, the building must meet current flood rules.
The City's floodplain definitions page spells out both halves of the test. Substantial damage is damage "of any origin" where restoring the building would cost 50% or more of its market value before the damage. Substantial improvement is any mix of repair, rebuilding, alteration, or addition "taking place during a 12-month period" whose cumulative cost reaches the same line.
The 12-month window is cumulative
The City starts the 12-month period on the date of the first improvement or repair of the building. A new roof in one season and a kitchen a few months later can land in the same total.
The definition adds one more line. If the building has incurred substantial damage, "any repairs are considered substantial improvement regardless of the actual repair work performed." A house hit hard enough once can cross the line on its first permit.
Why the City runs this test
The City's permit packet says these rules are required by the National Flood Insurance Program. It adds that a community must adopt and enforce them for federally backed flood insurance to be available to its residents. The packet aims the rule at houses below the base flood elevation, the level floodwater is expected to reach in the base flood.
What counts toward the 50% total?
Nearly every repair to the building itself counts, including finish work such as cabinets, flooring, and paint. Costs outside the building, and certain soft costs, do not. The City's repair application packet lists both sides.
| Item | Toward the 50% total? | City source |
|---|---|---|
| Foundation, slab, bearing walls, trusses, roof decking, re-shingling | Counts | Packet, items included |
| Drywall, paint, tile, carpet over subfloor, kitchen and bath cabinets | Counts | Packet, items included |
| HVAC, plumbing and electrical work, light fixtures, built-in appliances | Counts | Packet, items included |
| Demolition labor, overhead, and profit | Counts | Packet, items included |
| Improvements and additions in the same 12 months | Counts, added to repairs | Floodplain definitions page |
| Donated materials and volunteer labor | Counts, at a market price or wage rate | Packet, notice to owners |
| Plans, surveys, permit fees | Excluded | Packet, items excluded |
| Debris removal, mud removal, building dry-out | Excluded | Packet, items excluded |
| Furniture, throw rugs, free-standing refrigerators and stoves | Excluded | Packet, items excluded |
| Pools, screened pool enclosures, fences, sidewalks, sheds, detached garages, landscaping | Excluded | Packet, items excluded |
| Minimum work to fix health, sanitary, or safety code violations the building official identified | Not substantial improvement | Floodplain definitions page |
| Alteration of a historic structure that keeps its historic designation | Not substantial improvement | Floodplain definitions page |
Two details in the packet change the math more than owners expect. For damage repairs, the City says "pre-storm prices and rates will be utilized." Owners who act as their own contractor must also price their own labor at current market value.
How does the City set the structure value?
The City measures the 50% line against the market value of the structure alone, before the damage or work. The packet says it starts from the structure value the Property Appraiser's Office records, excluding the land.
The definitions page describes market value as actual cash value. That is replacement cost depreciated for age, wear and tear, neglect, and quality of construction. It comes either from a qualified independent appraiser or from the tax assessment value adjusted by a factor the Lee County Property Appraiser provides.
An owner who disagrees with that figure has one route the packet names. The owner "may engage a State of Florida licensed property appraiser" to submit an appraisal of the structure's market value. Because the land is left out, a house on a valuable lot can carry a low structure value, which lowers the dollar amount that reaches 50%.
What the City asks for at permit time
- An application for substantial improvement or substantial damage review, signed by the owner and contractor.
- A notarized affidavit from every owner, and a notarized affidavit from the licensed contractor.
- A complete cost estimate signed by a licensed general contractor, covering all damage, not just structural work.
- The signed contract and an itemized cost breakdown, with backup for every line.
The affidavits are sworn "under the penalties of perjury." They state that no other work will be done during the permit beyond what a valid permit covers. The packet warns that a false statement can lead to revoked permits, fines, and corrective action, up to demolition.
Sec. 110-28 of the City's code of ordinances has the floodplain administrator estimate market value before the work and compare it to combined repair and improvement costs. The section says the determination "requires evaluation of previous permits issued for improvements and repairs."
What happens when a Fort Myers house crosses the 50% line?
A house that crosses the line has to meet the City's flood rules before it is rebuilt. For a house with its lowest floor below the base flood elevation, that means raising the building, not just repairing it.
"If a building is 'substantially damaged' or 'substantially improved', it must be brought into compliance with our flood damage prevention regulations, including elevating the building to or above the base flood elevation."
City permit packet, City of Fort Myers FEMA Improvements/Repair Application Packet
The packet lists what that covers:
- An elevation certificate goes to the City to show the lowest floor's height. Garages and carports do not count as the lowest floor.
- Electrical and mechanical equipment, bathrooms, and laundry rooms must also sit at or above the base flood level.
- Below that level, only parking, building access, and limited storage are allowed.
- Plans must show how the building will be raised. In a V zone or coastal high hazard area, an engineer or architect must certify them.
One exception matters for sellers. If the lowest floor, its equipment, and its bathroom already sit above the base flood elevation, the packet says the building can be repaired "without having to comply with the 50 percent rule." Non-residential buildings may be flood-proofed instead of raised.
How did Hurricane Ian flood houses inside Fort Myers?
Hurricane Ian, which made landfall on September 28, 2022, pushed storm surge up the Caloosahatchee River into the city. The National Hurricane Center's Hurricane Ian report records maximum inundation of 5 to 8 feet above ground up the river in Fort Myers (National Hurricane Center, March 2026).
The same report says the tide gauge near downtown Fort Myers measured 7.26 feet above mean higher high water. There, surge "reversed the direction of the river flow and flooded the streets of the city." Along the river's southern bank downtown, the U.S. Geological Survey surveyed a high-water mark of 4.4 feet above ground.
The report places Ian's landfall on the barrier island of Cayo Costa as a category 4 hurricane. It puts damage at over $112 billion, the costliest hurricane in Florida's history. Its 10 to 15 foot figures belong to Fort Myers Beach, a separate town, not to the city.
How can you check a house's permit and flood record?
The City's own portals and staff hold most of the record a seller or buyer needs. Pulling it first shows where a house stands in its 12-month window and whether a review is already on file.
- Permits: The City moved permitting to its EnerGov portal (City of Fort Myers page, updated February 2025). Permitting answers questions at 239-321-7925.
- Flood zone and history: The City's floodplain page links a Forerunner flood information portal and a City flood map.
- Elevation certificate: The same page names the Building Services floodplain coordinator, at 239-321-7931, for flood information and elevation certificate requests.
- Open code cases: The City's code case search runs through the same EnerGov portal.
A Fort Myers mailing address is not proof a house sits inside city limits. Many nearby addresses are in unincorporated Lee County or another city, outside the City's rules described here.
An open permit or an unpaid City fine can follow a house to closing. The guide to selling a Fort Myers house with a City code lien covers that side.
What must you disclose when you sell a house after Hurricane Ian in Fort Myers?
Florida requires the seller of residential real property to give the buyer a flood disclosure at or before the time the contract is signed. The wording of the form is set out in Fla. Stat. 689.302 (Florida Statutes, 2026).
The form opens with a notice that homeowners' insurance policies do not cover flood damage. It then asks three questions:
- Whether the seller knows of any flooding that damaged the house during the seller's ownership.
- Whether the seller has filed a flood damage claim with an insurer, including the National Flood Insurance Program.
- Whether the seller has received flood damage assistance, including from FEMA.
The statute defines flooding to include the overflow of inland or tidal waters and rapid runoff from a river, stream, or drainage ditch. It also covers sustained standing water from rainfall. For a house that took river surge in Ian, the first question usually has a clear answer. The guide to the Florida insurance crisis and selling covers how coverage questions can shape a sale.
Repair, raise, or sell a hurricane-damaged house in Fort Myers as-is?
The choice usually turns on where the house stands against the 12-month total and how high its lowest floor sits. Repairing can fit when the total stays well under 50%. Selling as-is can fit when the next permit would cross the line and bring raising the house into play.
| Path | When it can fit | What the owner carries |
|---|---|---|
| Repair as-is | The 12-month total stays under 50%, or the lowest floor is already above base flood elevation | Contractor estimate, notarized affidavits, itemized costs |
| Raise and rebuild | The house is substantially damaged or improved and below base flood elevation | Elevation certificate, raising plans, equipment and baths moved above the flood level |
| Sell as-is | The next permit would cross 50%, or raising the house is not the plan | The Fla. Stat. 689.302 flood disclosure at or before the contract |
Questions some owners answer first
- Is the house inside Fort Myers city limits, or under another floodplain office?
- What permits were issued in the last 12 months, and when did the first one start?
- Does the Property Appraiser's structure value look right, or is an appraisal worth ordering?
- Does a repair estimate include cabinets, flooring, and paint, which the City counts?
- Where does the lowest floor sit against the base flood elevation?
What a buyer of a substantially damaged house takes on
A buyer takes the building as it stands, including its place in the 12-month window. The City's definition ties that window to the building and its first repair, and it says nothing about a change of owner.
If the house has already incurred substantial damage, the definition treats any repair as substantial improvement. A buyer who plans to rebuild a house below base flood elevation would face the raising rule and the same sworn affidavits. Buyers who expect that work may account for it in what they offer. The page on selling a house that needs major repairs covers the wider as-is picture.

Frequently Asked Questions
Does the 12-month repair window start over when a Fort Myers house is sold?
The City's definition ties the 12-month period to each building, starting on the date of the first improvement or repair of that building. The definition says nothing about a change of owner. A buyer can ask Building, Permitting and Inspections which permits already fall inside the window before planning work.
Can an owner challenge the structure value the City of Fort Myers uses?
The City's packet says it uses the structure value the Property Appraiser's Office records, with the land left out. An owner who disagrees may hire a State of Florida licensed appraiser to submit an appraisal of the structure's market value. A higher structure value raises the dollar amount that equals 50%.
Do debris removal and dry-out costs count toward the 50% total in Fort Myers?
The City's packet lists debris removal and clean-up, including mud removal and building dry-out, among the items excluded from the 50% rule. Plans, surveys, and permit fees are excluded as well. Repairs to the building itself, from framing to cabinets and flooring, are counted.
Do volunteer labor and donated materials count in a Fort Myers 50% review?
The City counts both at a market value. Donated or discounted materials are valued at what they would cost in a normal sale, and volunteer labor is valued using wage scales for that type of construction work. An owner acting as the contractor must also price their own labor at current market value.
Does a Fort Myers seller still owe the flood disclosure in an as-is cash sale?
Under Fla. Stat. 689.302, the seller of residential real property gives the purchaser the flood disclosure at or before the time the sales contract is executed. The statute lists no exception for an as-is or cash sale. An as-is clause speaks to the house's condition, while the disclosure records what the seller knows about flooding.
Is every house with a Fort Myers mailing address under the City's 50% rule?
The City's rule covers buildings inside the City of Fort Myers, and a Fort Myers mailing address does not prove a house is inside city limits. Many nearby addresses sit in unincorporated Lee County or in another city, which run their own floodplain reviews. Confirming the jurisdiction first tells an owner whose rules and window apply.
Can a Fort Myers house already above base flood elevation be repaired without the 50% rule?
The City's packet covers this case directly. If the lowest floor, including electrical and mechanical equipment and the bathroom, is already above the base flood elevation, the building can be repaired without complying with the 50 percent rule. An elevation certificate shows where that lowest floor sits. Garages and carports are not counted as the lowest floor.
