Section 100205 of BW-12 requires FEMA to phase out Pre-FIRM subsidized rates for nonprimary residences. On January 1, 2013, the NFIP began implementing this provision using an 80-percent occupancy threshold. Effective June 1, 2014, the NFIP will implement this provision by defining primary residence to be a building that will be lived in by the insured or the insured’s spouse for more than 50 percent of the 365 days following the policy effective date.
