Affordable Housing Policies and Programs


Permit Sonoma, the Sonoma County Community Development Commission, and other County departments operate a number of programs providing regulatory incentives and financing to promote and assist in the development and preservation of housing that is affordable, available, and accessible to the County’s low-income residents.

Why Affordable Housing Matters

Housing affordability affects the entire community—residents, businesses, the environment, and the economy:

  • A lack of affordable or available housing increases homelessness.
  • Extremely cost-burdened households (those spending more than 50 percent of income on housing) have little left over to pay for other necessary expenses—food, transportation, and health care and suffer lower health outcomes as a result.
  • A lack of affordable housing in urban centers forces people to commute long distances and move outside of the County, resulting in increased traffic and wear-and-tear on aging roads, lower quality of life, and lost economic output.
  • Slow housing growth results in a slower job growth and economic prosperity.

Sonoma County's Affordable Housing Programs

The following Permit Sonoma programs encourage the development of affordable housing:

  • Density Bonus Program

    A regulatory incentive for developers to build more affordable housing by increasing the allowable residential density and providing incentives to reduce housing costs.  

  • Single-Family Development Fee Deferral Program

    Accessory dwelling units may be constructed to defer payment of the affordable housing fee, provided that the unit be restricted for rent to qualified low-income households.

  • Multi-Family Fee Deferral Program

    Allows the payment of development fees to be deferred until the permanent financing for an affordable or special needs housing project is obtained.

  • Residential Development Program

    Requirement for all residential development to contribute to the County’s affordable housing program.

  • Workforce Housing Program

    Requirement for all non-residential developments to contribute to the County’s affordable housing program.

Affordable Housing Fees

As part of the affordable housing program, Permit Sonoma collects affordable housing fees for the new construction of residential and non-residential structures. These fees fund affordable housing development through the County Fund for Housing, administered by the Sonoma County Community Development Commission. Contact Permit Sonoma's Planning Division for more information on affordable housing fees.
