Enter your lot dimensions and your city's setback requirements. The calculator shows whether you have compliant space for a coop — and draws a diagram of your usable zone.
All measurements in feet. Use your county GIS parcel map or property survey for accurate lot dimensions.
Search "[your county] GIS parcel map" or "[your county] property search" online. Most counties have free interactive maps showing lot dimensions. Alternatively, your property survey (received at closing) has precise measurements. Your county assessor's records also list lot square footage, though not always dimensions.
This calculator uses rectangular lot approximations and straight-line distance measurements. Real lots may be irregular. Neighbor setbacks assume a neighbor's house at the side property line at the stated distance — your actual situation may differ. Always measure your specific lot before building. This is a planning aid, not a permit determination.
