Florida Building Code requires blower door testing for all residential dwellings

(Roy Lewis, CMI - North Florida Inspector) #1

Nothing new, but…
EFFECTIVE JUNE 30TH 2015
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.

R402.4.1.2 Florida Building Code - Energy Conservation
Requires blower door testing to confirm air leakage not greater than 7 air changes per hour. Testing must be done by an approved third party, and report provided to the building official.

R303.4 Florida Building Code - Energy Conservation
Requires a whole house ventilation system meeting M1507.3 when the air infiltration rate is less than 5 air changes per hour. (Which is what R402.4.1.2 above requires, thus all houses must have a whole house ventilation system.)

Yea, they started requiring 10 yr non replaceable battery smoke alarms 1-1-15 too.

To be clear, this is for new construction not resales?
