The wind mitigation form asks several dates about your home. The first in the title block is the “Year of Home:” This question is considered a to be the year the house was built. The year the house was completed or received its certificate of occupancy. Homes take time to build and before building a permit is applied for. This is the permit application date. This date determine what building code a home is required to be built to. This would also be the same case with any re-roofing permits. Building codes can change while the house is under construction, once a permit is issued, the building code that is in place at that time the permit is applied for is the code that is required to be followed. This is why, for instance a house can be permitted in the year 2000 but finished in 2002 and two.
