What are the benefits of having an ADU?

Installing an accessory dwelling unit has a variety of benefits. One immediate advantage is the flexibility in housing that an ADU provides, whether as a living space for family members to age in place or as a rental unit to produce income.

Apart from a rental property, the extra square footage could also serve as a private home office, a personal gym, an in-law suite, or even a guest house. Tailor the space to your specific needs and goals, making the most of your property and enhancing your lifestyle.

Best of all, a prefab ADU in Oakland can increase the value of your residential unit. With a potential 30% appreciation of your property, you could see a sizable return on your investment over the years.

Plus, prefab ADUs usually incorporate sustainable design elements, such as energy-efficient appliances, LED lighting, and low-flow fixtures, reducing overall energy consumption and water usage. The eco-friendly design of this type of ADU means you'll not only be saving money in the long run, but also doing your part for the planet.

Oakland ADU requirements

When buying a prefab ADU in Oakland, it’s crucial to have a thorough understanding of how to navigate permits, financing routes, and utility setup guidelines for a smooth ADU construction process.


How much does an ADU unit cost in Oakland?

The city of Oakland’s ADU calculator tool estimates that a 750-square-foot modular studio ADU costs roughly $296,000 to build. On the other hand, a two-bedroom, two-bathroom prefab ADU spanning 1,200 sq.ft. could set a homeowner back around $465,000.

However, the true cost of constructing an ADU in Oakland can fluctuate widely due to many variables, such as materials, labor, and unit size.

Building Permits

How do I get an ADU permit in Oakland?

The permitting process in Oakland requires planning and zoning permit approval before a homeowner can apply for a building permit.

The former involves consideration of the ADU’s size, height, and location, while the latter includes building code compliance, requiring documentation that details floor plans, and capacity charges.

When the city’s building and planning office gives both approvals, ADU construction can begin. There’s also an expedited process involving pre-approved ADU plans where the city has already given the green light to certain floor plans and designs.


What are the top ADU requirements in Oakland?

Under California state law, ADUs must have access to water and sewage services. The East Bay Municipal Utility District (EBMUD) has to grant approval for new water service, which requires filling out an application. In addition, the city’s fire marshal mandates that detached ADUs need a separate address, so most of these units will need their own gas meter.


How do I finance an ADU in Oakland?

The financing options for your prefab ADU in Oakland are as diverse as the city itself, from cash-out refinancing to home equity lines of credit (HELOCs). Opting for cash-out refinancing allows you to tap into your mortgage to secure funds for building an ADU.

With a HELOC, homeowners with a minimum of 15% to 20% equity in their main house can leverage that equity to access funds. Generally, financial institutions are willing to lend up to 85% of your home's equity, and interest payments only start to accrue when you withdraw money.

Additional ways to fund your ADU include tapping into your savings, such as from stock investments, and personal loans from relatives or close friends.

FAQs: Prefab ADUs in Oakland

Due to a variety of permit fees for zoning and inspections, the cost of a building permit for a prefab ADU in Oakland can run into the thousands.

Plus, considerations like the ADU's size, number of bedrooms, and whether the primary dwelling is a single-family home or multi-family property can affect the final cost of the permit. A good starting point for your ADU project budget is between two and eight percent of total construction expenses.

Whether it’s a studio or three-bedroom ADU, the city of Oakland has a height restriction of 1,200 sq.ft. for accessory dwelling units.

A prefab ADU in Oakland often comes with a range of appliances. Expect a fully functional kitchen with energy-efficient appliances like:

  • Stove or cooktop

  • Oven

  • Dishwasher

  • Garbage disposal

  • Refrigerator

Some units may also include laundry appliances, such as a washer and dryer, and a HVAC system, adding to the overall convenience and practicality of the living space.

For most homeowners in Alameda County and the San Francisco Bay Area in general, the time frame for adding a backyard home ranges between six to 10 months.

However, it can take several months alone to secure the necessary permits, especially if the city requires revisions to the initial submittal package, which could push the overall timeline of the ADU project to over a year.

When you partner with a trusted ADU builder like Abodu, the process of prefab ADU construction kicks off with a discovery call with a team member to discuss your budget and ideal build. You can also visit our showroom to see the types of ADUs available and experience them firsthand.

Next, a sales manager will provide an on-site consultation to determine where to place the ADU on your property, then walk through the contract with you to confirm the options, costs, and timeline. After you sign onboard, our team will take care of the permitting and building process in addition to site preparation.

Once the factory has completed your prefab ADU, we’ll deliver and install the unit on-site with a crane. Following finishing touches and final inspection by the city, you’re free to make the most of your new prefab ADU in Oakland.
