Do You Need a Permit to Replace Impact Windows in Palm Beach County?
Answer
Yes — Palm Beach County requires a building permit for every window replacement under Florida Building Code §105.1, whether you file with an incorporated city or the county directly. Even outside the HVHZ, unpermitted work voids insurance claims and triggers stop-work orders.
Florida Building Code §105.1 requires a permit for any work that changes a building's structure, weather envelope, or life-safety systems. Window replacement does all three — a single opening counts. Palm Beach County is non-HVHZ, so the rules are slightly different than Miami-Dade or Broward — Florida Product Approval is accepted instead of Miami-Dade NOA — but the permit requirement itself is the same.
Florida insurers routinely deny hurricane-damage claims when post-loss inspections find unpermitted window work. At resale, every Palm Beach title search runs a permit-history check; an open or missing permit on file blocks the closing until it's resolved.
