Building an ADU in Oakley

Introduction

As an Oakley resident, you may have imagined many ways to add an additional housing unit on your property: as a rental unit, a home for an elderly relative, a caregiver, or an older son or daughter living at home. An accessory dwelling unit (ADU), sometimes called a “second unit” or “in-law unit”, is a self-contained living unit on the same property as a primary residential building. These units generally include a living and sleeping area, kitchen, and bathroom. They can be detached from or attached to a home. You can also create an ADU by converting a garage or existing space in a home into a separate living unit. We are excited to let residents know that the process of adding an ADU to a residentially zoned property is easier than ever before.

The City works with residents each week to assess the options for their property and regularly approves building permit applications for ADUs. After talking with the Planning Division (925-625-7160) to confirm their property’s zoning, interested residents would then either commission custom plans from an architect or reach out to a company that specializes in prefabricated accessory dwelling units. When working with an architect or company to obtain plans, residents evaluate their needs for the space. Should the unit be large or small? Should it have a full kitchen and a mini-split air conditioning system? How much closet space should it have? Once the final design is settled on, the plans along with a building permit application are submitted to the Oakley Building Division. The Building Division takes roughly 15 days to review the plans and then either provide comments back or approve the plans. Whether you are looking to custom build an ADU or use a pre-manufactured home, the resources available on this page will assist you in moving forward. Learn more about ADUs by reviewing the Guide to Accessory Dwelling Units: An ADU How-to-Guide for Oakley Residents, Homeowners, and Property Owners.

ADU Accelerator Program – Senate District 7

New Program Provides Rebates for ADU Construction

Senator Steve Glazer, representing Senate District 7, has launched a newly created Accessory Dwelling Unit (ADU) Accelerator Program that offers rebates of up to $15,000 for new ADU’s that are deed restricted to low-income households (minimum of 20 years), and up to $7,500 for non-restricted ADU’s. This $2.5 million state-funded initiative is intended to encourage and facilitate the construction of 350 ADUs in qualifying cities and towns in Contra Costa and Alameda Counties. 

The City of Oakley will receive a total of $85,525.10, in the form of a one-time payment for the implementation of the ADU Accelerator Program.
