Do You Need a Permit to Replace Impact Windows in Miramar?
Answer
Yes — the City of Miramar requires a building permit for every window replacement under Florida Building Code §105.1. Miramar is in the HVHZ, where 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. Miramar is inside Broward's HVHZ designation, so there is no "like-for-like" exemption and no allowance for owners to self-certify HVHZ-rated installs.
Florida insurers routinely deny hurricane-damage claims when post-loss inspections find unpermitted window work, on the grounds that uncertified products may not meet the assumed wind-load resistance. At resale, every Broward title search runs a permit-history check; an open or missing permit on file blocks the closing until it's resolved.
