The 40 Year Recertification Ordinance was initially adopted by the Miami-Dade County Commission in 1975. It was replaced in 2001 by the current law which adopts the Florida Building Code and continues the requirement that buildings in Miami-Dade County after 40 years (and every 10 years thereafter) be re certified by a registered Florida Engineer or Architect for structural and electrical safety. This Ordinance applies to all of unincorporated Miami-Dade County and the incorporated Cities within the County.
