Meet Los Angeles homeowners who are ready to build.

ADUCheck shows homeowners what fits on their property before they call anyone. When they ask for a price, the request goes to partners who work in that area and build that kind of home.

Who we work with

Licensed, insured and working in LA City or LA County. We check every partner before the first request.

  • Architects and designers

    Homeowners who know what fits and want a designer for a custom ADU or for site plans around a pre-approved one.

  • Firms with pre-approved plans

    List every plan you hold for free, with your name on each one. Homeowners contact you for the plan set.

  • Builders and general contractors

    Quote requests from people with a report, a chosen plan and a timeline. California license required.

  • Trades

    Foundations, utilities, solar, surveys and soils reports, matched to projects in your area.

  • Lenders

    Homeowners asking how to pay for an ADU: renovation loans, HELOCs and construction loans.

How requests reach you

  1. The homeowner asks

    From a report or a plan page. They tell us what they want to build, when, and how they plan to pay.

  2. We match by area and kind of work

    Up to three partners per request, based on the neighborhoods you serve, the work you do and your plans.

  3. You reply within two business days

    Through your partner account or by email. The homeowner sees your name, license and past ADUs.

Partner terms come with your application reply. Listing plans is free; partners pay only when a homeowner asks them for a quote.
