The Town of Windsor partners with The Napa Sonoma ADU Center, which is an excellent resource for ADU/JADU regulations and requirements. They have Town pre-approved plans, provide site assessments, and offer webinars on a variety of topics related to ADUs.

When using the Napa Sonoma ADU Standard Plans gallery you can select our jurisdiction to see the plans that we consider to be pre-reviewed. 

Planning recommends submitting a concept site plan and elevations, to adu@townofwindsor.com to obtain staff guidance regarding design/architecture and privacy considerations, prior to submission of a building permit.

Housing Choice Voucher (Section 8)

The Housing Choice Voucher Program (Section 8) is funded by the Department of Housing and Urban Development (HUD) and administered by the Sonoma County Housing Authority. The program’s primary purpose is to provide rental assistance to low-income families for affordable, decent, safe, and sanitary housing. Recipients of the assistance receive a voucher to rent homes in the private market. The voucher covers a portion of the rent and the tenant is expected to pay the balance. The tenant's share of the rent is an affordable percentage of their income, which is generally between 30 to 40 percent of the monthly income for rent and utilities.
