City Building Inc was born of two brothers in 1976. Wally and Steve Baldwin were the youngest licensed general contractors in California when they decided to launch City Building Inc from their father’s San Francisco garage. Since then, CBI has gained a substantial presence throughout northern California. Originally headquartered in San Francisco, CBI now calls San Mateo home.
Over the years, CBI has met every project with a consistent standard of superior care and quality, which has allowed us to experience a sustained growth for the past four decades. While we do continue to grow and improve with every project we take on, we are proud of our 85% repeat clientele that is a testament to our reputation as a trusted and respected partner and contractor.
