San Jose ADU permits and regulations 2021
Determined to increase the city’s affordable housing stock, planners have put a lot of effort into making San Jose, California, ADU-friendly. The goal: to add 10,000 affordable housing units by 2022.
In 2019, Mayor Sam Liccardo unveiled a detailed plan to make the ADU building process streamlined and more affordable. In 2020, the city handled permits for about 600 accessory dwelling units, and it’s on track to handle 1,000 or more in 2021. Check out the resources below for more info.
