ADUs 101 Webinar for Napa & Sonoma County Homeowners

For those of you who missed our webinar, “ADUs 101 for Napa & Sonoma County Homeowners” never fear -- we’ve got the whole thing recorded and available right here for you on-demand (the video is also embedded below). This accessory dwelling unit webinar was a new format for us -- relevant to all 16 jurisdictions (aka all cities and the two unincorporated county regions) across both Napa & Sonoma counties. 

We were joined by two local ADU Experts, Scott Johnson of Pocket Housing and Robin Stephani of 8th Wave, who gave us a terrific overview ADUs 101, including:

    • Types of ADUs

    • Overview of new ADU state laws

    • The money side of ADUs (cost, taxes & financing)

    • Overview of ADU development process

    • Design tips for ADUs

    • And more!


Plus, we were joined by a local homeowner, Pia, who just wrapped up a successful garage conversion ADU in Santa Rosa! We walked through the details of her experience including cost, financing, and the whole building process.

Finally, we held a live homeowner Q&A with the help of Scott, Robin, Pia and our statewide expert on ADU law and policy, Joshua Abrams of Baird + Driskell Community Planning.

With nearly 800 homes destroyed or damaged, and more than 1,000 commercial and other structures burned (at time of publication) across Napa and Sonoma counties due to the Glass Fire, compounding the hundreds of homes lost in the LNU Complex fire just recently extinguished, the already existing need for housing in our communities has only deepened.

As we begin to rebuild together as a community coming out of these most recent tragedies, the nonprofit Napa Sonoma ADU Center is here to support homeowners better understand the ins and outs of accessory dwelling units (or ADUs, also known as granny flats, second units, or backyard cottages) to help build housing units for family members, teachers, nurses, firefighters, and others in need of homes.

Julia DeNatale, Vice President of Community Impact for Napa Valley Community Foundation shares, “We work side-by-side with local donors and nonprofits to tackle the most important challenges our Valley faces.  Even as we respond to disasters by distributing millions of dollars for COVID-19 and wildfire relief, we are working to meet our present and future housing needs.”
