Free ADU Feasibility

    Find out what ADU your property can actually support.

    Lot, zoning, setbacks, financing, rental income, and the realistic permit path. Before you ever talk to a contractor.

    Every ADU type

    Detached, attached, garage conversion, junior ADU. TRUbee scores which types your specific parcel can support and ranks them by expected return, not by what is easiest to build.

    Honest financials

    Build cost, expected rental income, payback period, five and ten-year profit. Numbers tied to your zip code's actual market, not a national average.

    Permit reality check

    California ADU law is generous on paper and slow in practice. TRUbee shows expected timeline, fee range, and the requirements most homeowners discover after they sign with a contractor.

    Assistant Bee

    How the assessment is built.

    TRUbee combines what is true about your parcel, what California law allows, and what the local market actually pays into a single report.

    What your lot can legally support

    The starting point is what your specific parcel is actually allowed to do under the rules your jurisdiction enforces today.

    Buildable envelope

    Once the rules are applied, TRUbee shows how much square footage you can realistically put on the ground in each ADU type.

    Local cost and local rent

    Build cost is anchored to your local market. Rental income is anchored to what comparable ADUs of the same size and bedroom count actually rent for near you.

    Honest risk flags

    When your parcel has a complication worth knowing about up front, the report says so before you spend money on plans.

    TRUbee does not publish how the pieces fit together. That is the part that keeps the numbers reliable when the market shifts.

    Why run the feasibility first.

    • Every ADU type is scored independently, so you see which option earns the most for your specific parcel rather than picking the first one suggested.
    • Permit fees, school fees, and utility hookup fees that California cities actually charge are included up front, so the budget you start with is the budget you finish with.
    • Local rental comp data sits on the same page as build cost, so the income side of the math is right there next to the spend side.
    • When you do meet a contractor, you walk in knowing what the project should cost and what it should earn. That conversation goes a lot more smoothly.
