APPENDIX I   DETERMINING SECONDARY ADDRESSES IN COMMERCIAL, INDUSTRIAL AND INSTITUTIONAL BUILDINGS AND STRUCTURES
   1.   Find the total number of swuare feet of given building footprints.
 
   2.   The maximum number of addresses allocated for a one story building is 99. Find the maximum square feet that can be allocated for each possible address.
      53,200       =   537 sq. ft./address
      99 possible addresses
   3.   Scale each suite or unit space.
 
   4.   Find the maxium number of addressess allocated for each unit. (The address range).
 
   5.   Assign the secondary addresses.
      Because each unit could be further subdivided, the assigned address should be chosen form the middle of the computed range. For example, Unit 1 is assigned an address of 116 because its range is 100 to 134.
      Address Range   Assigned Address
      Unit 1 - 100 to 134   116
      Unit 2 - 135 to 145   140
      Unit 3 - 146 to 159   154
      Unit 4 - 160 to 178   169
      Unit 5 - 179 to 199   189
 
   6.   Secondary unit numbers shall consist of three digits. For multi-story structures exceeding nine stories, four digit numbers shall be assigned. In cases where basements require secondary addresses, the three-digit number shall begin with '0'. The two right-most digits shall represent the unit number. The left-most digit shall represent the floor number.
