ADUs & Home Additions in Santa Clara, CA

A second unit that adds real value.

Santa Clara homeowners are building ADUs for the same reasons as the rest of the South Bay: rental income, multi-generational living, and the recognition that moving in this market costs more than building on your own lot. City of Santa Clara has been following state ADU law, and the process is workable for well-documented projects.

Most Santa Clara lots are modest in size, which means JADU construction within the existing footprint is often the right answer. For lots that have enough rear yard depth, detached ADUs of 600-700 sq ft are also feasible. We do the site analysis first and give you an honest picture of what’s possible before any design work starts.

Home additions in Santa Clara — room additions, family room expansions — are also common. We handle design, engineering, permits, and construction.
