San Francisco Bay Area
Garage-to-ADU Conversions
Turn an existing Bay Area garage into an accessory dwelling unit, with a kitchen, bathroom, living space and a dedicated entrance.
Fit an independent home inside the shell
Plan where to put the kitchen and bathroom while leaving enough usable floor area for sleeping, storage and everyday living. The old garage door opening can influence the position of the new entrance, exterior wall and windows.
Start with the existing garage
Bring interior and exterior photos, rough dimensions and any drawings of the original building. Review the floor, walls, roof and available utility connections before assuming how much of the garage can be retained.
Can both an attached garage and a detached garage be considered?
Both are worth discussing with the project team. The existing structure, access, utility routes and property-specific review will shape which conversion approach is feasible.
