See what your lot
can hold.
We pull your real parcel from county GIS, draw your existing home from rooftop imagery, layer state and local ADU rules, and propose buildable placements — with every dimension you can take to your architect or building department.
An architect, a surveyor, and a permitting expert — compressed into one workflow.
Real parcel data
Lot polygon and APN pulled directly from Santa Clara County GIS. Every dimension is sourced, not guessed.
Your actual house
Existing footprint drawn from Google Solar imagery — recent, accurate enough to plan around.
State + local zoning
CA Gov Code §65852.2 layered with local overrides (LA, SF, Pasadena, Los Altos, Mountain View, Palo Alto, San José).
Buildable envelope
Setbacks, height limits, and fire separation computed and drawn — never invented by the model.
Placement options
Two or three pre-validated ADU footprints. Pick one, iterate by chat, export a starting package.
Architect-ready
Site plan SVG + JSON design summary, with state vs local citations on every constraint.
