A homeowner in Oakland wanted to add space to her home that could be used as storage, a guest room, a laundry room, or a home office. New Avenue created this accessory building to enhance her property, making her home into a place that better suits her busy life.

For many homeowners, adding an accessory structure like this makes it possible to stay in the neighborhood they love. It’s an efficient way to add square footage to your home without the expense and difficulty of buying a new home in the area.

This ADU is loaded with extraordinary features including solar energy, an incredible storage loft, an accessible bathroom, and luxurious finishes.

When California passed AB 68, among other groundbreaking legislation related to ADUs, we were thrilled. The new laws gave California homeowners more rights related to adding ADUs to their property, including the right to add two accessory dwellings. So for most homeowners, the answer is yes, you can add two ADUs. Here’s a look at some plans for adding two ADUs developed for a client in Berkeley.

The homeowners’ New Avenue design professional created a home with one bedroom, a bathroom, a washer/dryer, a kitchen, and a living area with bamboo flooring. The family will be able to bring in around $3,000 per month in rental income. The ADU will pay for itself in no time, and they can also use the income to pay for the mortgage on the main home, education, travel, or anything else they may need.

New Avenue assessed the property to help the homeowners determine the best course of action. We found that the old ADU was built in 1932, at the same time as the main home. Structural damage, a weak foundation, and asbestos made the original cottage unsuitable as a home.

The family opted to build a new ADU. New Avenue’s experienced design professional created an accessory dwelling that fit beautifully on the property.

A nice one-bedroom home with a study like this will pay for itself in rental income. In San Jose, this rental home would bring in $3500 or more in rent. That’s enough to make mortgage payments on both the ADU and the main home.

We’re sharing some of our clients’ post-project thoughts. Here are some examples of what we hear from new ADU owners.

The home includes two bedrooms, a kitchen, a full bathroom, a washer/dryer, a living room, an attic, and plenty of storage space. A sun tunnel and plenty of windows provide natural light, making the home feel spacious and energizing.

The main art studio area is equipped with floor-mounted electrical outlets and receives tons of natural light through the unit’s clerestory windows and NanaWall, which easily folds back to open the entire front wall. The homeowners can enjoy the light and fresh air when the wall is open and will be protected from the elements when it’s closed.

Steve, a homeowner in Berkeley, wanted to add more space to his one-bedroom, one-bathroom home. He hired New Avenue to design and build a second story with an additional bedroom and an additional bathroom. Here are the plans and costs.

A homeowner in Mountain View asked New Avenue to create a 640-square-foot accessory dwelling that would serve as a comfortable home for a family member. Here’s what the project cost.

Many homeowners find that their detached garages could be more useful as something else: a guest suite, a home office, or a rentable accessory dwelling unit (ADU). Here are plans and drawings for one garage conversion project in Berkeley.
