The Best and Fastest Retail Builders in CA, AZ, NV, HI, ID, UT, WA, OK, NM, TX


Incorporated in 2008, Tri State General Contractors specializes in retail and commercial construction with licenses in CA, AZ, NV, HI, ID, UT, OK, NM and TX. In 2013 Dave Mason, Sr. was named President of Tri State General Contractors and brought over 34 years of construction experience to the company. Mr. Mason’s vast experience in the construction industry is exceptional. In the early 1990's Dave took his experience into the Retail Supermarket business and as Vice President of a prominent retail and commercial contracting firm, he helped grow that firm from a small commercial builder into a significant player in the retail construction industry. With Dave's strong leadership and knowhow he has helped Tri State reach these same milestones. Assisting its retail clients with their most complicated projects is Tri State's specialty. Their ability to pre-plan complicated sequencing and navigate through tough project challenges from pre-planning to close out is a large reason why Tri State's relationships and repeat business are so significant. Tri State's clients are confident that we will successfully perform and complete every project to their satisfaction, "on time" and "on budget".


Tri State General Contractors is a family-owned and operated company.  It employs two of Dave’s nephews, Donald Mason P.E., Vice President and General Superintendent DJ Mason, as well as his son, David Mason, Jr. Project Manager. All have grown up in the industry and have extensive backgrounds in all phases of construction. Tri State is very proud of the talented team they have in place and considers all of their employee's family.


With an impressive list of clients and customers, Tri State has experienced significant growth over the past several years. Tri State has

an extensive portfolio of projects ranging from very complex ground-up projects to simple tenant improvements. Tri State’s umbrella of services includes pre-construction recommendations, conceptual estimating, performs design assistance and gives constructability advice.  In 2016, a “Small Projects Division” was established, and in

May of 2017, the company opened a second location in Northern California in the city of Rocklin, just outside of Sacramento. Most recently, Tri State moved into a new office in San Marcos, CA. The new Southern California Headquarters is completely equipped with efficient offices, a warehouse facility, supply yard and Metal Works Shop. This is the perfect site for Tri State to serve its clients needs and continue to achieve success in the future.
