We are proud to serve the San Francisco Bay Area, including Napa, Sonoma, Solano, Marin, Contra Costa, Alameda, Santa Clara, San Mateo and San Francisco counties.

Alten Construction was established in 1995 by Bob and Shannon Alten with the dream of creating a cohesive construction team that works together to create amazing structures. By placing our clients’ needs first, we have grown from a small public works company to a thriving general contractor with more than 100 employees and more than $75 million in annual revenue.

We treat our clients the way we want to be treated, ethically and honestly. We take pride in our work, so that you can take pride in your finished structure.
