Building That Works for Tacoma Homes

Tacoma has a bit of everything—tight urban lots, steep slopes, craftsman bungalows, and mid-century homes with layout issues. We build to meet those challenges head-on, combining thoughtful design with sharp execution.

Signature Build is a full-service design-build firm serving Tacoma, Washington. We focus on custom homes, ADUs and DADUs, additions, and garage conversions—whether you’re rethinking your own property or developing new infill. Our team handles it all in-house, from early planning and permit coordination to the final punch list.

We’ve completed garage conversions in Central Tacoma, ADU construction in the Proctor District, and home additions in South Tacoma—always built to code and made to last.
