AB 1154 – No Parking Required for Small ADUs
More freedom, fewer hurdles—especially for compact housing
AB 1154 is a smart step toward making smaller, more affordable ADUs easier to build. The bill removes parking requirements for ADUs under 500 square feet and allows Junior ADUs (JADUs) with their own bathroom, even if there’s no owner living onsite.
This legislation eliminates two of the biggest design and permitting roadblocks: required parking and owner occupancy. For homeowners working with tight lots—or hoping to create flexible, independent housing—AB 1154 provides more room to get creative.
What This Means for You
If you're:
Adding a small backyard cottage,
Creating a JADU with a private bath,
Or working with a site where parking space is limited or impossible,
AB 1154 makes it easier—and legal—to move forward.
Key Benefits:
No parking required for ADUs under 500 sq ft, regardless of public transit access,
JADUs can include their own bathroom, increasing independence and livability,
No owner-occupancy requirement for JADUs (aligned with regular ADUs),
More design flexibility—no more shoehorning in parking spots or shared bathrooms just to meet outdated code,
Encourages the development of compact, creative housing in existing neighborhoods.
This makes a huge difference in dense areas, narrow lots, or hillside properties, where parking has been a deal-breaker for many potential projects.
