Engineered Trusses for California ADUs & Backyard Homes
ADU Trusses Built for California's Building Boom
California's ADU laws have made it easier than ever to build a second dwelling on your property. Whether you're building a detached backyard cottage, converting a garage, or adding a junior ADU within your existing footprint, Mike Walker Lumber Co Inc provides the engineered truss package to get your project framed quickly and permitted smoothly.
Since California streamlined ADU permitting, we've seen a surge in ADU truss orders across Sacramento, the Bay Area, and Northern California. Our engineering team understands the specific requirements: setback constraints that affect roof design, height limits that dictate truss profiles, and the various California ADU code provisions.
ADU Types We Serve
Detached ADUs (backyard cottages up to 1,200 sq ft), attached ADUs (additions to existing homes), garage conversions (new roof trusses when converting an existing garage), two-story ADUs and ADUs above garages, and junior ADUs (JADUs up to 500 sq ft within the existing home footprint). Each type has different structural requirements, and we engineer trusses accordingly.
Why Trusses Are Ideal for ADU Construction
ADUs are typically compact structures where every inch of interior space matters. Engineered trusses maximize usable interior volume by precisely controlling roof pitch, ceiling height, and structural spans. Trusses also install faster than stick-framing — critical on ADU projects where homeowners want construction completed as quickly as possible.
