Napa County is dangling a hefty financial incentive in front of local homeowners who have been toying with the idea of a backyard unit. The county will host an in-person information session on its Affordable ADU Forgivable Loan Program next Thursday, April 30, at Napa City Hall. Officials say the program is designed to cover a major chunk of construction costs for accessory dwelling units, with an eye toward creating more affordable rentals. The session is geared toward homeowners in all cities and the unincorporated county who may be willing to rent ADUs to income-qualified tenants.
County staff say the forgivable loans range from about $60,000 up to $105,000, depending on unit size and project details, and that the full amount can be forgiven if all program rules are followed over a five-year affordability term. “This program is a practical way for homeowners to be part of the solution to Napa County’s housing challenges,” Jennifer Palmer, Napa County Director of Housing and Community Services, said. As outlined by Napa County, the session will also walk through who qualifies as a tenant and how to apply.
What the session will cover
The free event runs from 6:00 PM to 7:30 PM and features an overview from the Napa Sonoma ADU Center, along with presentations from county planning and building staff on permitting, design and what comes next if homeowners decide to move forward. The event agenda highlights ADU basics, details of the county’s forgivable loan program and the City of Napa’s permitting process. Homeowners can sign up through Eventbrite and find additional tools and guides at the Napa Sonoma ADU Center.
How the loan works
The program layers a base forgivable loan with extra incentive funds so the total award can reach the program maximum, with specific base amounts and the detailed forgiveness schedule laid out in county program materials. Loan forgiveness builds over time as the homeowner keeps the unit affordable. Each year for up to five years, a portion of the loan is canceled while the ADU is rented at the required affordable rate. For full terms, income limits and the month-by-month forgiveness schedule, see the program guidelines on Napa County.
Why it matters
County officials and nonprofit partners say the goal is to expand affordable rental options for local workers while giving homeowners a way to add flexible housing without changing neighborhood zoning. The approach has already been recognized outside Napa, with the ADU loan program receiving recognition from the National Association of Counties for its community and economic development angle.
