One Stop Shop Program

One Stop Shop Pilot Program


On August 6, 2019, the San Mateo County Board of Supervisors approved the creation of a brand new One Stop Shop pilot program to help homeowners with second unit construction. In this One Stop Shop program, participating homeowners will receive no-cost support from the nonprofit Hello Housing with the design, permitting, and project management involved with building a second unit. The One Stop Shop pilot program is a partnership of San Mateo County, Hello Housing, and the Cities of East Palo Alto, Pacifica, and Redwood City. Residents of these three cities and the unincorporated county will be eligible to apply for inclusion in this pilot program.

While the formal application to participate has not yet opened, and specific eligibility requirements are still being determined, San Mateo County is collecting an interest list of homeowners who want to stay informed.  If you are interested in the pilot program, similar offerings in other cities, or other informational updates about building a second unit, such as new financing options or changes to second unit regulations, please visit or complete the form at the very bottom of this webpage to sign up for updates.
