Legislation Requirements:
The Fifth Edition of the Florida Building Code (FBC) requires blower door testing for all residential dwelling units. This would include single family houses, town houses, duplexes, and each condominium and apartment unit where the building is three stories or less.  House Bill 535 has further revised this requirement. As presently revised by HB 535, all residential dwelling units must have a maximum air changes per hour (ACH) of seven (7). In addition,  if the ACH is less than three (3), mechanical ventilation is now required.
