Window Permits & Wind Code in DeLand

The reasoning is worth having even where the requirement may not reach you. A sealed building lets wind pass around it. Lose a window on the windward side in a serious storm and the inside comes up to outdoor pressure, pushing up under the roof at the same moment the wind outside is pulling it off. The roof is caught between two forces going the same way. That is why the Florida Building Code concentrates on glazed openings — the opening is the first domino.

Buildings inside a wind-borne debris region are required to protect those openings, either with impact-rated glazing or with shutters. Both are in the code; neither is a guarantee, and "hurricane-proof" remains a word that tells you about the salesperson rather than the product.

Whether the debris-region requirement reaches a property is decided by mapping — distance from open water and the design wind speed at that spot — and DeLand sits roughly twenty miles back from the Atlantic. Many addresses this far inland fall outside the region, and the honest thing to say is that if you have been sold impact glazing on the basis that the code demands it, that claim deserves checking rather than believing.

Check it yourself, on the county's own map rather than on our say-so or anyone else's: Volusia County wind speed and debris region mapping.

Two cautions against reading too much into a good answer. Being outside the debris region is not the same as being outside the wind code — a design wind speed still applies to replacement windows, and it is not a small number anywhere in Florida. And a storm that has crossed the coast still arrives here; inland means less exposed, not exempt.

Replacing windows and doors is permitted work. Volusia County states that replacements must meet the wind loading of the current Florida Building Code, and that satisfying it may bring shutter requirements with it — the age of what you are removing confers nothing on what goes back. The county sets out the process at its permit and zoning center, and inside city limits the DeLand building department may hold jurisdiction instead.

Repairing what you already have is a different matter. Reglazing a sash, replacing a pane, refitting a sash cord — that is maintenance rather than alteration, and it does not drag the current wind code along behind it. Which is one more entry on the list of reasons the repair-or-replace question is worth asking before anything else.

And in a historic district there may be a second approval covering how the change looks from the street, running on its own schedule alongside the building permit. Ask the city early. It is a much better conversation to have before an order is placed.

Written August 2026, general on purpose, and covering the wind code, the debris region and the permitting of replacement windows in west Volusia County. It is not a code interpretation and not a decision about any particular property. On a house that has stood for eighty or ninety years, what applies depends heavily on what has been altered since and whether it was permitted at the time.

Two authorities matter here rather than one. The building department with jurisdiction over your address decides the structural and permit questions. If the property sits in one of DeLand's historic districts, the city may also review changes to what the street can see — a separate process, on its own timetable, and worth asking about before you order anything rather than after.
