Homeowner ADU Information

ADU Shed 2
ADU Urban

ADUs are a way to provide space for your family, friends and out of town guests, an affordable rental unit, or just a private studio space in your own backyard. Some people even build one to live in and rent out their house. There are so many possibilities and we’re here to help you through the process, step by step. 

The Pre-Approved Accessory Dwelling Unit Program encourages the construction of ADUs by offering property owners a selection of pre-approved ADU building plans that can be downloaded from this page or purchased from the plans library (coming soon!). The program assists property owners in creating ADUs by providing architectural plans, expediting the building permit process, and reducing pre-construction fees.
