The Short Answer
Yes — every new window or door opening in Tavares requires a building permit. This is a structural change: you're cutting into the wall, adding a header, and recalculating bracing. Tavares is in Lake County, not a coastal high-hazard zone (HVHZ), so impact-rated glazing is not mandatory — but that's the main local distinction that saves you cost versus homeowners in Brevard or Orange counties.
Tavares Building Department treats new window and door openings as structural modifications that always require a permit — no exemption for 'small' openings. The critical local angle: Tavares sits in Lake County (inland), which means you avoid the Florida Building Code High Velocity Hurricane Zone (HVHZ) impact-glazing requirement that would add $30–$50 per square foot to window cost in coastal counties like Volusia or Brevard. However, Tavares is still in Energy Compliance Zone 2 (per IECC amendments adopted by the city), so your window U-factor, SHGC, and VT ratings must meet Florida's stringent energy codes — expect plans to require glazing spec sheets. The city's permit portal is self-serve online (verification needed with local staff), and plan review typically takes 2–4 weeks for a single-window opening; if you're adding a header to a load-bearing wall, expect the review to flag bracing calculations and sheathing verification. Unlike some Florida municipalities that allow owner-builder work for the homeowner's own residence under Florida Statutes § 489.103(7), Tavares requires a licensed general contractor for structural work — framing, header install, and bracing — even if you pull the permit yourself as the owner.

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

Tavares new window or door opening — the key details

Every new window or door opening in Tavares requires a permit because you are cutting into the wall envelope, removing sheathing and studs, and introducing a structural header. This is not a replacement-in-kind (which has looser rules) — it's a wall modification. The fundamental rule is IRC R602.10 (bracing) and R612 (window fall protection): when you remove studs, you must install a beam (header) to carry the load above the opening, and if that wall is load-bearing, the header sizing must be calculated by a licensed engineer or derived from prescriptive tables in the IRC based on span, snow load, and roof load. Tavares sits in Climate Zone 2A per IECC 2023 (the city adopts the current Florida Building Code, which references IECC), so your new windows must meet a maximum U-factor of 0.30 and SHGC of 0.25 — stricter than federal minimums. Your permit application must include a plot plan showing the opening location, a wall section drawing showing the header size, on-center stud spacing, and the connection details to the surrounding framing. If the opening is in a bedroom (per IRC R310 egress rules), the window must be at least 5.7 square feet of net glass area and operable from inside without tools — if it doesn't meet egress, you cannot legally cut that opening, and the permit will be denied.
