About LotFoundry

LotFoundry is an ADU feasibility studio. Enter an address to explore estimated rent potential, build cost ranges, and payback for an accessory dwelling unit on a lot you already own — then connect with builders when you are ready.

Homeowners deciding whether their backyard can earn, and builders who want consented feasibility snapshots matched to their service areas.

Every rent, cost, and timeline figure is an estimate, not a guarantee and not professional engineering, legal, or financial advice. Local zoning, utilities, and permitting still need verification with your city and licensed professionals.
