Longboat Key FEMA 50% Rule: What Condo Buyers Should Know

October 8, 2026
The substantial-damage rule in the Town of Longboat Key's flood ordinance decides whether an older ground-level condo on Longboat Key can be repaired or has to be rebuilt higher. It compares the cost of repairs with the market value of the building before the damage, and the land is left out of that value. If repairs come to more than half the building's value, the work has to bring the whole structure up to current flood rules. The price a buyer pays covers the lot, the location and the walk to the Gulf. The rule only looks at the structure on top.
That is where buyers of older stock tend to be caught off guard. The structural inspections they have heard about since Surfside cover taller buildings. In the one-story complexes that date from an earlier era of island building, the flood rule decides the outcome. This October, one of those buildings shows the process step by step.
The condo building at 380 North Shore Road sits on the narrow street where beachgoers park for the northernmost public beach access, the one at Greer "Beer Can" Island. As the Longboat Observer reported on October 4, 2026, a tarp is pinned to the storm-damaged roof with sandbags and the units are empty. The Manatee County Property Appraiser lists it as an uninhabitable condominium.
After hurricanes Helene and Milton, the town estimated the cost to repair the building at $2.9 million. The condo association then submitted its own quote of $974,718, which falls under the 50% threshold. The two figures are nearly three times apart, and the building's future depends on which one holds. A repair permit application filed on the last day of 2025 was closed after town staff's questions went unanswered. On September 28, the town's building official declared the building unsafe and unfit and gave owners 30 days to apply for permits. That puts the deadline at October 28, 24 days from today.
Longboat Key Planning, Zoning and Building Director Allen Parsons described the town's figure as a starting point:
"We provide a substantial damage estimate. It is not a final accounting of costs. It provides the property owner an opportunity to have their own cost estimate provided, so if their cost estimates repair is less than 50% of the value, then they have the opportunity to make those repairs."
The money and the bureaucracy also made the outcome uncertain. A unit owner, who owns one of the nine units with another owner, said one insurer paid fairly. The other required an attorney, and those funds arrived only about six months ago. The owner also described a board that is pushing for a rebuild, which she would not choose for a home of her own. For a buyer, that kind of disagreement within an association can matter as much as the estimate.
The rule itself comes from the Town of Longboat Key's flood ordinance. The floodplain administrator estimates the market value of the building or structure, or requires the applicant to get an appraisal from a qualified independent appraiser. For repairs, value is measured before the damage happened and before any repairs are made. The administrator then compares that value with the cost of the repair, the improvement, or both together.
Three practical points follow from that wording.
The size of the denominator decides how much damage a building can absorb. A modest older structure on a valuable lot has a smaller margin before it crosses 50% than a newer, more valuable building on the same street.
The numerator is open to dispute. The town uses cost-estimating software called Xactimate, and owners must provide their own estimate before permits are issued. At 380 North Shore Road, the whole case comes down to the gap between those two numbers.
History counts too. For repairs of flood damage, the ordinance requires staff to review earlier permits issued for flood-related repairs, as set out in the code's definition of substantial damage. A building's past repair permits can affect how the town reviews its next one. That makes a property's permit history part of what a buyer is taking on.
The town's 2025 annual report covered the year from October 2024 to September 2025. It shows how widely the storms tested this rule. The Longboat Observer summarized it in March 2026.
| FY2025 storm recovery, Town of Longboat Key | Count |
|---|---|
| Residential units assessed for damage | About 3,000 |
| Units found with no damage | 1,418 |
| Units with damage at 1% to 49% of building value | 1,586 |
| Units with damage above 50% of building value | 75 |
| Storm-damage repair permits issued | 2,183 |
| Houses demolished | 121 |
| Houses raised | 8 |
| Repetitive-loss properties that completed mitigation, out of 190 | 19 |
The largest group in the table is the 1,586 units with damage below the threshold. Permits for those units are also now on record, and the ordinance asks staff to review those records the next time flood damage is repaired. Forerunner's case study, quoting town staff, puts the number of substantial-damage notices at about 80. The sources do not explain the gap between that figure and the annual report's 75. Parsons has also said FEMA audits the town's permits for compliance with the 50% rule. That gives the town a reason to apply the rule strictly.
Most condo buyers in Florida now ask about milestone inspections and structural integrity reserve studies. Those rules apply to buildings at least three habitable stories tall. On Longboat Key, the inspection results were reassuring. All 198 buildings required to have milestone inspections passed. Only two needed the deeper Phase 2 review, and neither required a follow-up permit for structural repairs, according to the Longboat Observer's report from April 2026.
The cost of the inspection law shows up in reserves. Mayor Debra Williams said quarterly payments have gone up quite a bit because associations now have many more reserve items to fund. David Novak of Longboat Private Services, which manages more than 900 residential units, wrote that associations that have to catch up on reserves can face costs high enough that some owners sell.
A one-story building like 380 North Shore Road falls below the three-story threshold for milestone inspections. For low-rise buildings, the deciding factor is how much flood damage they take and how that damage is valued.
Meeting current flood rules is a major construction project. In a 2025 letter to the owners at 380 North Shore Road, Longboat Key Building Official Patti Fige wrote that the biggest requirement would be raising the building 10 feet above base flood elevation. Raised structures are already common on North Shore Road.
In the Village, owners have already made these choices. The Longboat Observer reported that one Village owner said repairs to his and his son's Helene-damaged homes would cost more than half their value. Both houses were demolished. A 1937 Village cottage took about two and a half feet of water during Helene. By April 2025 it had been raised about 12 feet, and interior restoration was still underway.
The town lets owners go higher than the minimum. The Florida Building Code baseline is base flood elevation plus one foot of freeboard, and Longboat Key allows an optional two additional feet islandwide. Ordinance 2024-07, adopted June 28, 2024, allows up to five feet of total freeboard on qualifying low-lying properties, subject to its flood-zone and coastal exclusions. Rebuilding at 380 North Shore Road would follow the path the unit owner described: "It would be great if we could rebuild it and rebuild it high. It was built for a different time."
Current market conditions give buyers time to ask these questions. In August 2026, Sarasota County condos and townhomes had 5.2 months of supply and a median of 83 days on market before going under contract. Sellers received a median of 91.6% of their original list price. In Manatee County, the figures were 4.9 months, 72 days and 93.4%. These are countywide numbers for condos and townhomes combined, not Longboat-only figures.
For an older low-rise condo or cottage, ask for these items in writing:
None of this is legal, tax or insurance advice. Confirm the details with the Town of Longboat Key's Planning, Zoning and Building Department and with your own attorney and insurance professional.
No. Longboat Key's ordinance measures the market value of the building or structure. For repairs, that value is measured before the damage happened.
Yes. The town's figure is a preliminary substantial-damage estimate, and owners may submit their own cost estimate. If the owner's estimate comes in under 50% of value, they can make the repairs.
For flood-damage repairs, the ordinance requires staff to review earlier flood-repair permits under the code's definition of substantial damage. Ask the town how it applies that definition to the property you are considering.
