Lot Coverage

Lot coverage is the ratio of the occupied area (buildings and driveways) to the total area of a lot. The coverage provisions are based on a sliding scale that’s determined by the zoning district of your lot, although these provisions are only applicable to these zone districts: R-5, R-6, R-8, R-10, and R-20. You can find out your zone here. Use this worksheet to determine your lot coverage.

Homes with front porches and detached garages in the backyard gain an incentive “bonus” when calculating lot coverage — properties with one or both or those features are eligible to increase their maximum lot coverage by a certain amount of percentage points. Learn more about the specific allowances by zone here.

Currently, the Zoning Ordinance includes, but is not limited to, the following items in lot coverage calculation:

  • main buildings* (resting directly or indirectly on the ground), detached garages and accessory buildings with or without foundations
  • paved driveways and parking pads
  • pergolas
  • above-ground swimming pools
  • bay windows

Examples of items that are not included are:

  • air conditioners and compressors with or without foundations
  • sidewalks and walkways
  • areaways going from ground level to basements
  • play equipment, picnic tables, benches, and other outdoor furniture

Lot coverage provisions are applicable to both new construction and additions, and any homes that do not conform to these guidelines (adopted in November 2005).
