Why we built this

Sixplex deals look strong on unit count until parking and construction type catch up. This tool makes that visible early.

When a scenario looks promising, take the next step on a real address — zoning, lot dimensions, setbacks, and height limits are free tools on Bucky.

FAQ

Does this include elevators?
Not as a separate line. Fold elevator cost into hard cost $/sf or soft costs if your code path requires one.
Does this read my zoning?
No. This is an assumption calculator — you set lot size, costs, and rents. For parcel-backed zoning facts, use Bucky’s free address tools or a project workspace.
Who is this for?
Developers, architects, and planning consultants who want a fast “does this typology pencil?” check before committing to a site or detailed study.
