Enter your lot dimensions and local setbacks. Instantly see the maximum buildable square footage and which floor plan sizes fit your lot.
Check your local zoning ordinance for exact setback requirements
How this works: Buildable area = lot area minus all setbacks. Max footprint = 55% lot coverage (typical residential zoning maximum). SF estimates assume 90% efficiency (walls, mechanical) for single-story, 85% per floor for two-story.
Note: Actual buildable area may differ based on easements, flood zones, impervious surface limits, HOA restrictions, and other local regulations. Always verify with your local building department before purchasing land or designing a home.
