Converting a garage to a music studio and adding an accessory dwelling in Berkeley

How one Berkeley homeowner converted his garage into a studio and added a rental unit that could pay for it all.

Many homeowners choose to convert their existing garages into accessory dwellings. This usually involves demolishing the garage and replacing it entirely. Some opt for a garage remodel and an ADU to pay for the project.

Nicola, a Berkeley homeowner, asked New Avenue to remodel his existing garage into a music studio and storage area. He also wanted an ADU to use as a guest house, additional space when needed, or rental home.

Nicola’s New Avenue designer created a design for both buildings and worked with the city to permit the entire project.

Below is the site plan. “The Box” is the designer’s nickname for the garage conversion. “La Casetta",” which is Italian for “little house,” is the name of the new ADU.

Here’s the floorplan for “The Box.” It includes a music studio, a storage room, a washer/dryer, a half bath, and an attic for even more storage.

Here’s the floor plan for the ADU. It has a kitchen, a living area, a bedroom, a full bathroom, a washer/dryer, and attic storage.

The ADU, which the homeowner can rent out for about $3,000 a month, can pay for the mortgage on the entire project. Meanwhile,, the homeowner has a music studio for his work and plenty of storage space.
