ADU Feasibility Studio

LotFoundry helps homeowners evaluate an accessory dwelling unit before spending money on plans. Search an address or open a sample parcel, place an ADU on the lot, and compare estimated rent, build cost, payback, setbacks, lot coverage, and zoning signals in one workspace. Change the unit dimensions and assumptions to see how the scenario responds, then save or share the feasibility snapshot when you have a direction worth exploring.

The studio is designed for early planning, not permit approval. Parcel boundaries, zoning data, setbacks, construction costs, rents, and timelines can be incomplete or change over time. Treat the results as estimates that help you ask better questions, then verify critical dimensions and local requirements with the city, a surveyor, designer, contractor, lender, or other licensed professional before making a building or financial commitment.

If you are still learning the basics, start with our city-by-city ADU rule guides, learn more about how LotFoundry works, or visit Help for product guidance. These public resources explain the assumptions behind the studio and give you a path to the source material before you move from feasibility into design and permitting.
