Standard ADU Plans

ACCESSORY DWELLING UNITS (ADUs) 

Accessory Dwelling Units (ADU’s) are additional residential units on the same property as a primary dwelling. They can be a great way to add extra living space, generate rental income, or provide housing for family members.

AB 1332 PRE-APPROVAL ADU PLANS

AB 1332 allows local governments to offer pre-approved ADU designs that homeowners can choose from to simplify the approval process. These pre-approved designs are already vetted for compliance with local zoning codes and building regulations, allowing homeowners to bypass some of the more lengthy and complicated parts of the permitting process.

PRE-APPROVED ADU PLANS

The plans listed below will require site specific information and permit approval. We have provided links to the pre-approved ADU plans and designers contact information.
