Start with an address
We pull the parcel, zoning, setbacks, and overlays from the county and city — labeled so you can see what's verified and what's modeled.

How it works
Three steps. Answer first, paid features after.
02
See the likely path
Detached, attached, conversion, or JADU — ranked by what actually fits your lot. Each path shows its blockers and what would change the answer.
03
Know the next real step
One step, not a list of twelve. A photo of your panel. A call with a builder who has permitted on your block. Nothing busywork.
