Generally the occupancy is limited by the size of the structure. Simply put, you must have a minimum of fifty (50) sq. ft. per person in a bedroom (minimum bedroom size is 70 sq. ft) and the bedrooms must meet the minimum requirements of the housing code. The other factors are defining a family unit. A family unit is defined as parents and their children or other blood relatives or, for the purpose of regulating occupancy; no more than three (3) unrelated people living together as a household unit.
