What CANNON BUILDING does

Cannon Building is a privately held, Southern California general contractor founded in 1994 and headquartered in Placentia, CA, with a regional office in Carlsbad (San Diego County). The company delivers construction services across four verticals: Life Science, Healthcare, Commercial/Institutional, and Industrial. Its life science and healthcare practice is the primary differentiator, with specialized technical capabilities in cleanrooms, high-purity piping systems, USP purified water systems, and FDA-regulated pharmaceutical manufacturing environments, supported by active membership in ISPE. Adjacent work spans aerospace cleanrooms (Meggitt), biopharma complexes (Bachem, Gilead, Genentech, Neutrogena/J&J, Edwards Lifesciences, Pacira), hospitals and surgery centers (Riverside Community Hospital, DISC Sports and Spine, Orange Coast Memorial), industrial cold-storage conversions (Anheuser-Busch), institutional/preservation projects (Christ Cathedral, Scripps Research), and large-format corporate relocations (Edwards, Meggitt).

The company operates a project-based services model with six core service lines: Preconstruction, General Contracting, Design/Build, Facility Shutdowns/Turnarounds (300+ executed), Facility Maintenance, and Construction Management. These are delivered by a direct enterprise field-sales team with no intermediary channel, leveraging long-term client relationships and repeat business. Pricing is per-project and negotiated, with no public disclosure of rates. The firm holds California General Engineering (A), General Building (B), and C10 Electrical licenses plus Arizona B-1 General Commercial Contractor licensure, and reports 1,200+ completed projects since inception. It is family-led (Tim J. Cannon as President, Nolan Cannon as Project Manager) with a dedicated executive team (CFO Atef Moussa, Senior Executive Manager Kevin Thompson, Senior Estimating Manager Eliot Hansen, Field Operations Manager Greg Bartholomew) and approximately 101–250 employees.

Cannon Building's go-to-market emphasizes enterprise-level construction in technically demanding life science and healthcare environments, partnerships with engineering firms (The Austin Company, EXP Engineers on the Bachem program), and a prequalified subcontractor network. Revenue is generated through fixed-price and cost-plus contracts across Southern California (Orange County, San Diego County, Los Angeles, Inland Empire) with an emerging Arizona presence. The model is relationship-driven, with documented repeat engagements at marquee clients and recognition including California Preservation Award, ENR Award of Merit, Docomomo US Modernism in America Citation of Merit, and Orange County Business Journal Best Places to Work (2019).
