CAM 220, Lot Coverage, Height and Yard Standards for Homes in Single Family Zones, was updated to incorporate two code changes that affect single-family development. The first change relates to height measurement – the method of measuring height has become more straightforward, particularly for sloping lots, by allowing the use of an average grade. The second change is related to a new limitation on how lot coverage is calculated, and is focused on how the lot area is determined for unusually shaped lots.
DR 4-2012, Height Measurement: Calculating Average Grade Level, describes the two formulas for calculating the average grade level from which to measure height structure. This rule went into effect April 18, 2012.
