Bakersfield is one of California's fastest-growing cities, and with rising home prices and rental demand, Accessory Dwelling Units (ADUs) have become a practical solution for homeowners. Whether you're looking to:

House extended family,
Create a passive income stream,
Increase property value,

an ADU can offer all that—if it's done legally with the proper permits.

California state law supports ADU development, and Bakersfield follows state-mandated ADU ordinances. That means it's easier than ever to get your ADU project approved—especially if you follow the right steps.

Detached units (in the backyard),
