Ground Floor Conversions in the San Francisco Bay Area

Pinnacle Construction specializes in converting unused ground-floor areas into functional, comfortable living spaces throughout San Francisco and the Bay Area. Many homes in San Francisco were originally built with underutilized ground-level storage or garage space. Our team provides the structural, framing, and finish work required to turn these areas into bedrooms, family rooms, ADUs, offices, or flexible living spaces that support everyday use.

We coordinate with architects, structural engineers, and city inspectors to complete these conversions safely, efficiently, and in alignment with local building requirements.
