Accessory Dwelling Units (ADUs) are attached or detached homes on the same lot as a primary residence. They have areas for living, sleeping, eating, cooking, and sanitation. They can't be used for short-term stays of less than 30 days.
Take the time to figure out which ADU fits your needs and budget. Three types of ADUs on lots with primary Single-Family homes are classified by the construction of new or the use of existing facilities. Please review the categories below:
Please note that only one Category One AND one Category Two ADU may be combined on the lot with one JADU, up to three ADUs. However, if you already have an existing ADU (Category One, Two or JADU) an additional ADU of the same type may NOT be added. If a lot has three ADUs, one must be a JADU.

No matter which category of ADU you choose, you need the applicable permits. All ADUs require Planning Permits and Building Permits. When preparing to apply, take the following steps first.
Substep 1: Confirm Your Zone
The City of Oakland typically permits ADUs on properties located within residential or mixed-use zones.
Subtep 2: Design Your ADU(s)
General Requirements
Design Methods
Before you start building your ADU, you must create and get your ADU design approved. You can design your own ADU, or you can choose another way to design your ADU.
Although not required, a designer, licensed architect, or engineer is recommended to design the ADU and a licensed contractor to build it. Some companies provide both services. It is helpful when professionals have worked in Oakland and know the local permitting process. Contact references and look at the candidate’s previous work before making your selection.
