Building California Since 1987
Built on Trust.
Executed with
Authority.
Over five decades of disciplined construction, proper licensing, and long-term client relationships. Structural integrity from the ground up.
ADU & Home Expansion Specialists
California's Most Capable ADU Contractor
Proper ADU execution requires more than finish carpentry — it demands structural knowledge, infrastructure capability, and licensing authority. TDQ Construction brings all three.
Our Class A license enables us to handle civil and infrastructure components — sewer laterals, utility tie-ins, site grading — that most residential contractors cannot legally perform.

Why TDQ Construction
A Rare Combination of License & Experience
TDQ holds a Class A General Engineering license — a qualification that allows us to legally perform civil and infrastructure components many residential-only contractors cannot. Fewer subcontractors, tighter scheduling, one accountable entity.
The majority of our work comes from repeat clients and professional referrals — a direct reflection of performance and reliability built over more than five decades.
