From Commercial Artistry, to a leader in Design-Build


For six decades, WeidnerCA has consistently enhanced our client’s vision. It started in 1955 when an entrepreneurial police officer started hand-painting signs to earn extra money. Since then, WeidnerCA has grown to become a trusted partner for some of California’s most noteworthy developers, contractors, and companies across the West Coast.

Whether it's new construction or a renovation, we'll add value to your project


Through a commitment to fabricating artfully crafted products, mitigating risk, and designing practical solutions, we create long-term value for our clients and their properties. By removing the distance between designer and builder, we take uncertainty out of the equation and our clients enjoy the best return on their investment.

WeidnerCA is evolving the West Coast experience

Our body of work encompasses tens of thousands of projects delivered across many project types, with a unique focus on multi-family residences, healthcare environments, higher education and corporate campuses. Our trusted reputation has attracted long-term relationships with top developers and contractors from Los Angeles, San Francisco, Silicon Valley and beyond.
