Why we built this

Fiveplex programs need more lot and more capital. A fast pencil test screens weak sites before design spend.

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

When does fiveplex beat fourplex?
When the lot and financing support the fifth unit without a parking or soft-cost spike that eats the extra rent roll. Use the sliders to test that trade-off.
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.
Bucky — the pre-development platform

The pre-development platform that turns an address into sourced site intelligence, project analysis, and decision-ready deliverables.
