The Marin County is creating partnerships with homeowners motivated to build an ADU/in-law unit. They've created a new ADU Technical Assistance program for homeowners to help make the process less overwhelming. Free feasibility and project management support provided by HelloADU and paid for by the County is now available for homeowners who live in the Unincorporated Areas of the County. Our team of design and construction experts are ready to help you figure out what's possible with your property.
Submit your online application. The application will (1) determine your initial eligibility (2) provide the HelloADU team with some basic information about your ADU/JADU vision and your readiness and (3) to confirm your understanding of what Marin County's HelloADU can and can’t do for you. It should take about 15-20 minutes to complete.
The County's program is subject to a waitlist for all applicants who have applied following the initial lottery. All new applications received will be placed on a waitlist in the order that they are received.
HelloADU's team will reach out to schedule a phone conversation which includes a discussion about your potential project, potential costs, timeline and process. If following the phone call your project is a good potential candidate for Marin County's HelloADU program and you are still interested and ready to move forward, we will schedule a site visit.
At the Site Visit, we will walk your property together, learn more about your vision, review any sketches or drawings to date (if available), take measurements, locate utility connections, identify site conditions that may impact feasibility and construction cost, and discuss the pros and cons of alternative approaches.
