The Short Answer
Yes. Every new window or door opening in Naples requires a permit, period. Because Naples is in Florida's High Velocity Hurricane Zone (HVHZ), your opening must also comply with impact-rated glazing and wind design pressures — rules that don't apply in inland Florida cities.
Naples sits squarely in Florida's High Velocity Hurricane Zone (HVHZ), which means the Florida Building Code amendments for Miami-Dade and Broward counties apply to your project. This is the critical local difference: a new window opening in Naples must meet impact-resistant glass or shuttering requirements (per FBC Chapter 6, Section 6.2.1), plus wind design pressures tied to Naples' 140+ mph three-second gust speed. A similar opening in Ocala or Tallahassee would only need standard tempered glass and basic header sizing. The City of Naples Building Department enforces the FBC (not the IRC) and requires impact ratings on the permit plans before review even begins. Header design, wall bracing recalculation, and exterior flashing details are mandatory, but the hurricane-impact component is what sets Naples apart from most of the state and will add $800–$2,000 to your window cost. Plan for 2–4 weeks review, two inspections (framing and final), and expect the permit office to flag any plan that omits impact-glass specifications.

What happens if you skip the permit (and you needed one)

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.
