Many California homeowners build accessory dwelling units, or ADUs, on their properties.
While many of these ADUs are freestanding tiny homes installed in backyards, it’s also possible to convert garages into apartments with their own addresses.
The exterior of a garage turned into an accessory dwelling unit, an additional living space on the same lot as a main house that has its own address. Suszi Lurie McFaddenAfter learning that people in Europe convert garages into living spaces, commercial-real-estate veteran Rebecca Möller set off to start a company that helps Americans do the same.

Möller uses proprietary wall panels and parts prefabricated in a factory that allow transformations from garages to apartments to take about four weeks after proper permits are secured.

While Möller waits for the building permits to start the conversion, she hooks up the utilities, like water and electricity, which are typically connected to the main house.
Möller is able to build studio, one-bedroom, or two-bedroom units in garages, depending on their size. They cost homeowners between $150,000 and $250,000 to build.
Before any transformation starts, the garages look like this one — unfinished — with roll-up doors. Rebecca MöllerMöller turned this San Jose garage — previously used for storage — into a studio apartment. Aging parents who live in the main house built it for their child, who is also their caregiver.

Möller installs concrete slabs — called stem walls — around the perimeter of the unit. To turn the garage door into a proper exterior wall, the stem wall has holes where the windows will go.

After converting the garage door into an outer wall, Möller paints the front to match the rest of the house. Courtesy of Rebecca MöllerThe new front door for this unit, which cost the homeowner $185,000 from start to finish, is on the side of what was once the garage.
There is a small patio by the new front door. Courtesy of Rebecca MöllerMöller covered the stucco facade with paint, just like the rest of the house, and made the trim white.

The floors are a mix of bamboo and cork. Courtesy of Rebecca MöllerThe queen-sized Murphy bed pulls down to reveal artwork with cherry blossoms.

Owners have the option of buying furniture off of Möller’s recommendations or to furnish it on their own.
The kitchen is located in the corner of the unit.
There is ample floor space in the studio when the bed is folded up. Rebecca MöllerThe kitchen countertops are quartz and the appliances are stainless steel.
To the left of the appliances for cooking — an electric stovetop and a stainless steel convection oven — is a 24-inch refrigerator. Rebecca MöllerThe bathroom, located at the foot of the bed when it is folded down, has a classic sink and a quartz-lined shower.
The bathroom door is a sliding barn door to save space. Courtesy of Rebecca MöllerHere’s the “before” view of a garage in Burlingame that Symbihom turned into a high-end apartment.

Möller uses stove hoods from Broan or Klein. A washer-dryer is tucked in the corner of the kitchen. Rebecca MöllerA sliding barn door leads from the living room to bedroom, which has a bathroom through the open door on the left and a walk-in-closet with sliding doors on the right.
