The Short Answer
A new window or door opening — any opening not a like-for-like replacement of an existing one — requires a permit from the City of West Melbourne Building Department. This includes structural review of the header, bracing calculations, and in the High Velocity Hurricane Zone (HVHZ), impact-rated glazing and pressure design certification.
West Melbourne sits in Brevard County's High Velocity Hurricane Zone, which means the city enforces Florida Building Code (FBC) wind-speed and impact-glazing requirements stricter than the state minimum — your opening must be designed for 150 mph sustained winds and impact-rated glazing is mandatory, not optional. Unlike inland Florida cities (e.g., DeLand or Winter Park), West Melbourne's building department also requires a third-party review of header sizing and wall-bracing calculations for load-bearing walls, which adds 1-2 weeks to the permit timeline and typically $150–$300 to plan-review costs. The city uses an online permit portal, but for structural projects (which new openings are), plan submission and review happen in the portal system with staff markup — not over-the-counter approval. Owner-builders may file their own permits under Florida Statutes § 489.103(7), but you must provide engineered plans for the header and demonstrate compliance with HVHZ wind-load and impact-glazing standards; the building department will not approve hand-drawn sketches. The city's permit fee schedule starts at $300 for a single opening and scales with project complexity; if the wall is load-bearing and bracing recalculation is required, expect $500–$700 total.

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

West Melbourne new window/door openings — the key details

Any new window or door opening that enlarges an existing opening or cuts through a previously solid wall is a structural modification and requires a permit from the City of West Melbourne Building Department. The distinction is critical: a like-for-like replacement (same opening size, same framing) follows Florida Statutes § 553.993 and is exempt from permitting if you use a licensed contractor or file a homeowner-affidavit; but a new opening—whether you are enlarging a 3x4-foot window to 4x6 feet or creating a door where a wall once was—triggers full code review. The opening must comply with IRC R612 (fall protection from windows), IRC R703 (exterior covering and flashing), and for load-bearing walls, IRC R602.10 (bracing requirements). In West Melbourne's High Velocity Hurricane Zone, the opening must also meet Florida Building Code Chapter 12 (High-Velocity Hurricane Zone requirements): glazing must be impact-rated and certified for 150 mph wind loads and 52 psf positive/negative pressure. The permit application must include a plot plan showing the opening location, elevation drawings with window/door frame details, header sizing calculations (stamped by a licensed engineer if the wall is load-bearing), exterior flashing and house-wrap details, and a window/door manufacturer's specification sheet confirming impact rating.
