San Jose is California's third-largest city and the heart of Silicon Valley. ADU demand here is extremely high, driven by tech workers, high housing costs, and one of the strongest rental markets in the country.
San Jose ADU rents range from $2,400–$3,800/month for quality units. The combination of high rents and rising property values makes San Jose one of the best ADU markets in California.
