Property calculators.
Understand the numbers.
Test the area arithmetic behind a property study. Change the assumptions, see the result and share a numeric scenario with your team.
Setback & lot envelope calculator →
Enter a rectangular lot’s width and depth, then separate front, rear and side setbacks. See the remaining rectangle in a diagram, including when the entered setbacks leave no area.
Answers: what rectangle remains inside these assumed yards? It does not locate the legal lot lines or establish an approved building footprint.
Floor area ratio calculator →
Multiply lot area by FAR and compare that floor-area cap with lot coverage and an assumed number of stories. Use square feet, acres or square meters.
Answers: how do these area assumptions compare? It does not determine permitted homes, use or development rights.
Use the right tool for the question
- Confirm the parcel and governing authority with the parcel verification guide.
- Find the applicable inputs using the zoning-by-address guide and official code and map references.
- Compare the geometry and floor-area arithmetic. Keep parking, access, overlays and current amendments as separate checks.
Both calculators use your entered assumptions. A saved scenario link contains numbers and units only; it is not a property report.
Start with an address.
Review available parcel and mapped zoning evidence before registering. Coverage varies by property.
