Building an ADU
If you are considering expanding your Bay Area home or seeking more functional indoor space, consider building an ADU. Opting for an ADU gives you a cost-effective way to expand your home and can be used in several ways. We leverage our nearly 20 years of ADU construction experience at Valley Home Builders to deliver quality ADU planning, design, project management and building.
The Significance of Building an ADU in the Bay Area
An Accessory Dwelling Unit (ADU) is a permanent structure utilized as a secondary living space and offers many possibilities for property owners. In 2016, the Bay Area’s SB 1069 legislation launched a statewide and national surge in ADUs. In March of 2022, the Bay Area Council chose to build on this success by proposing additional reforms to make getting your build approved less costly, easier and faster.
With the bill offering additional funding for ADUs in the state, the popularity of these living accommodations continues to grow. Creating a secondary space attached to or detached from your main house provides versatile solutions to suit your wants and needs. These designs include garage conversions, tiny homes, backyard cottages and more.
Benefits of Accessory Dwelling Units
Whether you want to build a space for yourself, family members, caretakers or renters, some benefits of ADUs include:
- Flexible living space: A customized build allows many shapes and sizes of living areas to suit your intended needs, such as establishing a more manageable living space for empty nesters without leaving the neighborhood or allowing multigenerational families to gather under one roof.
- Positive environmental impact: The smaller size of ADUs decreases your carbon footprint by generally consuming less in utilities and shortening your commute with incorporated recreational spaces.
- Improved infrastructure: A secondary living space allows you to reconfigure the structure on your property in cities with high populations, providing a viable alternative to waiting for more housing to be built or finding a different place to live.
- Increase property value: Adding additional living to your residential space can offer a 20-30% increase in the worth of your property, depending on your location, size and features of the ADU.
Potential Uses for Accessory Dwelling Units
If you already know what you would like to use an ADU for or need some inspiration, the customization for these builds offers these opportunities:
- Support family members: An additional living space provides alternative housing options for family members, such as in-law quarters or a backyard cottage for adult children to live at their parents’ home with some added privacy.
- House on-site caregivers: The added component of an ADU provides families with the convenience of keeping a nanny or live-in nurse on the property while maintaining privacy and independence.
- Receive additional income: A possibility for short- and long-term rentals through guest house services or with tenants offers a way to earn revenue.
- Create home gyms or offices: The ability to create a home office, studio or gym space provides homeowners with accommodations right from their property, letting them save money by eliminating transportation expenses and membership fees.

FAQs
How much can an ADU increase my property value?
Adding an ADU to your residential property can offer a significant boost to its value. Depending on your location, the size of the ADU, and the features included, you can see a property value increase of 20-30%. This makes building an ADU not just a way to expand your living space, but also a smart investment in your home’s equity. Combined with the flexibility to use the space for your own needs or generate rental income, an ADU is a financially savvy decision for many Bay Area homeowners.
What's a good reason to build an ADU if I want to support aging parents or family members?
An ADU provides the perfect solution for multigenerational living arrangements. You can build in-law quarters or a backyard cottage on your property, allowing aging parents, adult children or other family members to live close by with their own private space and independence. This arrangement keeps families together while maintaining boundaries and privacy. It’s also more cost-effective than moving to a larger home or paying for alternative housing or care facilities.
Can I generate income from an ADU?
Absolutely. An ADU offers excellent income potential through short-term and long-term rentals. You can use it as a guest house for visitors, or rent it out to tenants to generate steady rental income. This passive income stream can help offset the cost of your ADU investment and provide additional financial flexibility. It’s one of the most popular reasons homeowners choose to build ADUs in the Bay Area.
Is now a good time to build an ADU in California?
Yes, now is an excellent time. In 2016, California’s SB 1069 legislation launched a statewide surge in ADUs by making them easier to build. Then in March 2022, the Bay Area Council proposed additional reforms to make approval less costly, easier and faster. The state is also offering additional funding for ADUs, and these legislative changes have significantly reduced barriers to ADU construction. Valley Home Builders can help you navigate the current favorable regulatory environment.
What's the environmental benefit of building an ADU?
ADUs have a positive environmental impact in several ways. Because they’re smaller than traditional homes, they generally consume less in utilities like electricity and heating, reducing your carbon footprint. Additionally, having a secondary living space on your property can reduce commuting needs for family members or renters, which means fewer car trips and lower emissions. For environmentally conscious homeowners, an ADU is a sustainable housing solution that benefits both your property and the planet.
