Southwest Florida specifics · The 50% Rule
The Threshold That Turns a Repair Into a Compliance Project
If the cost of repairs or improvements reaches half the structure's value, floodplain rules can require the entire building to be brought into current compliance — which may include elevating it. That is a different project from replacing windows.
Tell us the address and whether the property has been repaired since 2022. That second answer decides whether this is a window job or something larger.

A quote that does not survive the permit
The mistake is treating window replacement as an isolated scope. It is not isolated if it forms part of a wider improvement, or if the property was already assessed as substantially damaged. Costs are looked at cumulatively against the value of the structure, and once the threshold is crossed the obligation is not to the windows — it is to the whole building. A homeowner who has budgeted for glazing can find themselves holding a determination about elevation, and none of that appears on the window quote.
What to establish before spending anything
- Whether the property has ever been assessed as substantially damaged.
- Whether it sits in a special flood hazard area, and in which zone.
- What other work is planned, and whether it will be counted together.
- How the local floodplain administrator values the structure.
- Whether earlier repairs since 2022 already count toward the total.
Why this became a live question across the region
After the 2022 storm a very large number of properties in Collier and Lee went through damage assessment. Substantial damage determinations were made at a scale the region had not previously dealt with, and the consequences of those determinations are still working through the housing stock.
For anyone planning improvement work now, the practical point is that the assessment history of the property matters as much as its current condition. Two identical houses on the same street can face completely different obligations depending on what was determined about each of them.
How we handle it
- 01Ask the question at first contact rather than at permit stage.
- 02Point you to the floodplain administrator before you commit money.
- 03Keep our scope clearly documented so it can be assessed properly.
- 04Say plainly when a job has stopped being a window job.
We raise this early because finding out late is genuinely expensive and there is nothing we can do about it once a determination has been made. The people who answer it are at the county or the municipality, not here, and we would rather send you to them at the start than be the contractor who never mentioned it.
Said plainly
Where we stop
We are not floodplain consultants and nothing here is a determination. The local floodplain administrator decides how the rule applies to your property, and their answer is the one that counts. What we can do is make sure the question gets asked before you have spent money on the assumption it does not apply.
FAQ
Common questions
- Does replacing windows on its own trigger this?
- On most properties, a straightforward window replacement is well below the threshold on its own. The risk is cumulative — window work as part of a larger renovation, or on a property already assessed as substantially damaged, is a different situation. Ask before assuming which one you are in.
- Who decides whether the rule applies to me?
- The local floodplain administrator at your county or municipality. Not a contractor, and not us. It is worth a phone call before you take quotes, because their answer changes what you should be getting quoted for.
- Does it mean my house has to be elevated?
- It can mean bringing the structure into current floodplain compliance, and depending on the property and the zone that may include elevation. It is exactly why the determination should come before the budget rather than after it.
What we install
Impact Windows
The core product. In Collier and Lee the common situation is not an old house with old windows — it is a reasonably new house that was built fully compliant using shutters, with glazing that was never rated at all.

Sliding Glass Doors
On this coast the sliders open onto the lanai and they are the widest thing in the building. On a property that took water in 2022 they are also where the evidence of it is easiest to read.

Impact Entry Doors
An approved entry door is a whole assembly — slab, frame, hinges, lock, threshold and any glazing — approved as one thing. On this coast the threshold detail matters more than most people expect.
Read more →
Impact Garage Doors
In most houses the double garage door is the widest opening in the whole envelope. In Collier and Lee it is also the one nearest the ground, which drags it into a conversation that has nothing to do with wind at all.

French & Specialty Shapes
Arched heads, radius transoms, oversized fixed glass and French pairs are fabricated for one opening in one house. In a region still working through a rebuild, the queue in front of them is longer than the brochure suggests.

Glazing Into Existing Frames
Where existing frames are sound and an approval exists for glazing into them, changing only the glass is cheaper, faster and far less disruptive. On this coast it suits the condominium stock particularly well.

A Two-Year-Old Rebuild
Most Florida markets deal with old repair work of uncertain quality. Here the work is recent, and the problem is the opposite one: it has not had time to settle, and a share of the people who did it are no longer in the state.

Wind Product, Water Market
Impact glazing is tested against a flying object and a pressure cycle. It is a wind product. In the parts of this region worst hit in 2022, the destroying force was water, and no window on the market addresses that.

Newer Houses, Shutters
Much of this region's housing stock is recent and was fully code compliant when built — using shutters rather than rated glazing. Owners assume a newer house has protected openings. Often it has panels in the garage instead.
