The Florida Keys is navigating a housing market reshaped by a permit freeze that has made new construction allocations unavailable until at least July 2027. Buyers seeking homes built to current code face a choice: wait for a competitive permit process with unpublished scoring rules, or purchase an older home that carries a building right and replace it. According to Sandra Tuttle, founder of Island Welcome Real Estate, the second option is increasingly common and is changing the composition of the housing stock in ways that appear in price data before any permit report.
The Keys market has never been driven by new development, and Tuttle notes that the allocation freeze, while procedurally significant, does not by itself move prices. Instead, it redirects demand. Buyers who want a home elevated above flood levels and rated for 180-mile-per-hour winds cannot obtain one through raw land in the current window, so they turn to teardowns. The properties being acquired for redevelopment are typically at the bottom of the value range: ground-level conch houses, older fish camps, small frame homes, and mobile units built decades before current code. Many have flooded, some repeatedly.
“By removing older homes, tiny homes, small fish camps, and mobile homes from our inventory and replacing those with a brand new home, just naturally we are going to be elevating the average price point of this community,” Tuttle said. The replacement homes feature metal roofs, impact-rated windows and doors, and elevation above the base flood. They cost more to build but insure for less, widening the gap between what was removed and what is built.
The statistical effect is that average and median prices in affected neighborhoods rise without any individual property appreciating. A $500,000 ground-level home leaves the inventory and a $1.6 million elevated home enters it, moving the neighborhood average. For sellers holding older stock, this creates a confusing signal: published appreciation figures reflect inventory replacement as much as price movement, and a seller pricing an unimproved 1980s canal home against those figures may sit on the market.
The key variable determining whether a property is a candidate for redevelopment is not condition or price but whether the parcel carries a ROGO exemption, meaning it previously held a legally established residential unit and has public utilities. Such a parcel retains a building right permanently, allowing the existing structure to be demolished and replaced without entering the allocation system. The replacement is not restricted to the original footprint or square footage; current building codes and setbacks are the only limits. This distinction is not visible in a listing, and two adjacent lots at similar prices can differ entirely, with the one carrying the exemption worth materially more to a buyer planning to build.
Monroe County anticipates roughly 588 of the 900 allocations authorized chainwide, released at approximately 40 per year across at least a decade. Against a vacant land inventory in the thousands of parcels, that is a small fraction, and scoring will prioritize owner-occupied, affordable, and workforce housing. The implication is that redevelopment of existing parcels, rather than construction on raw land, will account for most new homes in the Lower Keys for the foreseeable future. The value attached to a lot carrying a building right is likely to continue separating from the value of whatever is standing on it. Tuttle, who works in unincorporated Monroe County and specifically in Summerland Key, has watched this pattern accelerate.
