Calculation Method Summary

  1. Convert lot size to acres using 43,560 sq ft per acre.
  2. Compute base allowed units as lot acreage multiplied by base density and round down.
  3. Compute maximum units with bonus as lot acreage multiplied by base density multiplied by 4, then round down.
  4. Compute units above base as proposed units minus base allowed units, not below zero.
  5. Compute required attainable units as round up of 15% of units above base.
  6. Apply AMI rules: min at or below 80% AMI rounds to nearest whole, max at 100% to 120% AMI rounds down, and remaining units are 80% to 100% AMI.
