This Fontana garage conversion on Monterra Dr transforms a garage into a complete 363 sq ft one-bedroom, one-bathroom ADU — Vision ADU's craftsmanship brought to San Bernardino County.
The kitchen features gray shaker cabinetry, quartz countertops, and a full appliance set including a gas range, over-the-range microwave, and refrigerator. A pull-out pantry cabinet beside the oven makes smart use of the compact footprint.
The unit is equipped with energy-efficient mini-split heating and cooling and a tankless water heater, keeping utility costs low while freeing up interior space. The bedroom includes mirrored closet doors and a ceiling fan, and the bathroom is finished with a modern vanity and a clean shower enclosure.
Fontana and the greater Inland Empire have become one of the most active regions for ADU construction, with garage conversions offering the fastest path to a legal rental unit. This project shows how a standard garage becomes comfortable, independent housing.
