Pinnacle Construction turns garages and unfinished lower levels into living space for San Francisco homes. We build from plans prepared by the architect and engineer and schedule required inspections during construction.
Older garages and lower levels may have low ceilings, moisture, limited natural light, or framing that needs to change. We manage the construction needed to turn the approved plans into comfortable living space.
The square footage is already there. Our job is to make it usable, integrated with the home, and worth more over time.
From demolition and framing to insulation, drywall, and final finishes, we keep the process organized and moving.
The engineer evaluates the existing structure; we complete the framing changes shown in the plans.
Complete approved floor or framing changes that provide more usable ceiling height where feasible.
Add insulation, finished walls, and moisture protection for a comfortable interior.
Update core systems to serve the converted space safely and functionally.
Add or replace openings to improve access, light, ventilation, and overall usability.
Complete the interior so the converted space feels like part of the rest of the home.
Build the bathroom or kitchenette shown in the plans when the conversion is part of an ADU.
Add the doors, windows, light, and airflow required by the project plans.
