The City of Sonoma has finalized the acquisition of two local apartment properties, safeguarding 18 affordable housing units in the community for at least the next 55 years.

The properties acquired are Setzer Senior Affordable Apartments (8 units at 673 First Street West) and Maysonnave Apartments (10 units at 270 First Street East). These homes will continue to serve low-income seniors and families, with rents capped on average at 30 percent of 80 percent of Sonoma County’s area median income (adjusted by household size).

This preservation effort was made possible by a partnership between the City of Sonoma, Burbank Housing, the Bay Area Housing Finance Authority (BAHFA), and the San Francisco Housing Accelerator Fund. The City contributed $250,000 from its Affordable Housing Trust Fund, BAHFA provided $4.5 million through its Housing Preservation Loan Pilot, and the Housing Accelerator Fund delivered additional loan financing. Burbank Housing will now assume responsibility for ownership, rehabilitation, and long-term affordability management.

Sonoma’s Commitment to Affordable Housing

Preserving these 18 homes is part of the City of Sonoma’s broader efforts to expand and protect affordable housing opportunities for local residents. The City supports affordable housing development through:

  • The Affordable Housing Trust Fund, which helps leverage outside funding and secure long-term affordability.
  • Development agreements and inclusionary housing policies, requiring or incentivizing affordable units in new projects.
  • Regional partnerships, working with local nonprofits, county agencies, and state and regional authorities to fund and preserve housing.

Under this new agreement, the homes will remain affordable for at least 55 years, and tenants will be able to stay even if their incomes increase modestly, ensuring long-term stability while keeping units affordable for future residents.
