ADUs

TSP Remodeling turns under-used yards and garages into fully finished accessory dwelling units that feel like a natural extension of your home. From concrete and framing to cabinetry, tile, and trim, our licensed crew handles every trade in-house, keeping the site tidy and the timeline on track while you watch the structure take shape right in your own backyard.

Based in Brentwood and serving nearby towns such as Oakley, Discovery Bay, Antioch, Concord, and Walnut Creek, we build detached cottages, garage conversions, and in-law suites that meet today’s codes and tomorrow’s comfort. Expect solid craftsmanship, clear communication, and a hand-off date you can plan around—no surprises, just a move-in-ready ADU built to last.
