What happens if you skip the permit (and you needed one)
- Stop-work order and $500–$1,500 civil penalty from City of Naples, plus you'll owe double the original permit fee when you finally pull one retroactively.
- Insurance denial: many homeowners' policies in HVHZ won't cover window or door claims if the opening was installed without a permit and didn't meet impact-glass standards.
- Lender or title company blocks refinance or sale; HVHZ non-compliance on residential windows is a red flag that freezes transactions.
- In a hurricane or storm, an unpermitted, non-impact opening is a liability — engineering will show it failed, and your insurer can deny the entire claim or seek recovery.
Naples new window or door opening permits — the key details
Every new window or door opening — whether it's a bedroom egress window, a slider to a new lanai, or a pantry porthole — is treated as a structural modification in Naples because it requires header sizing and wall bracing recalculation. The Florida Building Code (FBC), which Naples adopts by municipal ordinance, requires that you submit a framing plan showing the header design, post placement, and cripple-stud bracing (FBC Section 2304, which mirrors IRC R602.10 for wall bracing). The City of Naples Building Department will not issue a permit until a licensed engineer or architect signs off on the header if it spans more than 4 feet or if the opening is in a load-bearing wall. If the wall is non-load-bearing (interior wall, or exterior wall with roof loads above), a smaller header may suffice, but you still need a plan that shows the opening size, header depth, and fastening. The permit review checklist specifically flags missing header calculations — it's the #1 reason for rejection in the Naples office. Expect to redraw and resubmit if your original header detail is missing or undersized.
