Erin’s new attached ADU can be used as a guest suite, additional space for the homeowner, a home for family, or a rental unit. This kind of ADU rents for $2,500 or more per month, which will be enough to pay for the project and additional expenses such as helping with the mortgage on the main home, travel, education, leisure activities, or retirement.

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.

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.

This successful entrepreneur knows a good opportunity when she sees one. That's why she decided to add an ADU and live in it herself. (She plans to rent out her main house.) While she didn’t feel like she needed the additional income, she knew it would be a great investment.

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 owner of a multi-family home in Berkeley came to New Avenue for a major remodel of a two-bedroom, two-bath rental unit. While parts of the unit were salvageable (e.g., the beautiful redwood and a few of the walls), this unit was almost entirely rebuilt. It needed a new foundation and major work in all areas.

At $1,500 a year, the tax increase on this project breaks down to $125 per month. The homeowner easily recoups that with the savings on housing costs. The owner’s mother would have to pay $2,000 per month for a one-bedroom home of her own. If the family rents the unit out, they’ll bring in at least $2,000 per month in rent.

If Patricia rents out her new ADU, she can use the rental income to pay for the mortgage on the main home and the mortgage on the ADU. Or she can use the money to cover other expenses such as education, travel, retirement…anything she needs now or in the future. Here are the floorplans and elevations for Patricia’s new ADU in Berkeley.
