What is an ADU?
An ADU (Accessory Dwelling Unit) is a secondary residential unit built on the same property as a primary home. They can be detached structures, attached additions, or garage conversions.
How long does it take to build an ADU?
ADU construction timelines vary depending on size and permitting but typically range between 4 to 8 months from the start of design to final inspection.
Are ADUs allowed in San Diego?
Yes. California laws heavily support ADU development to address housing shortages, and many properties in San Diego are eligible to build accessory dwelling units with streamlined permitting.
