About us

We are a General Contractor with 81 years of construction expertise. Midstate’s projects include multi-family, office, retail, industrial, hospitality, parking structures, public works and historical renovations. We build quality and relationships one project at a time.

We strive to serve our clients with an unparalleled level of quality, integrity, reliability and professionalism to achieve their objectives with on-schedule and on-budget performance.


During its long history, Midstate has consistently maintained the same marketing philosophy: identify and retain good clients through cost effective, quality construction. Midstate is not signatory to any craft union agreements and can solicit and use the best proposals from both union and non-union subcontractors. Midstate delivers quantifiable results for its clients and provides superior construction management.


Midstate has experienced professionals who will monitor all aspects of your construction project. We place a high value on effective communications. Our team approach recognizes the strength of staff stability. We employ project teams that are comprised of the best estimating staff, project managers and superintendents in Northern California. These construction professionals have lived in the Bay Area and worked for Midstate for most of their careers, some of them for more than twenty years.
