ADU Resources

Here are resources, local and regional, to help you with an ADU project.

HOUSING TRUST SILICON VALLEY
ADU Workshops & Financial Assistance 

Housing Trust Silicon Valley offers free educational workshops as well as financial assistance to Bay Area homeowners who are seeking to build an ADU.

Visit the Housing Trust Silicon Valley's website for information.

San Jose PREAPPROVED ADU Program

One way to lower the overall cost of an ADU is to work with a vendor who offers ADU designs that are preapproved by the City. Construction and permitting costs on these units are typically much less than those for a custom-designed ADU.

See the ADU/Single-Family Master Plan webpage for more information.
