What we build in Bay Area.
The Bay Area commercial market is dense, fast, and unforgiving on schedule. The tech sector - Google, Apple, Meta, Salesforce, Adobe, NVIDIA, and the hundreds of mid-stage companies fitting up R&D, lab, and office space - keeps the TI market hot through any economic cycle. Restaurant and QSR rollouts in San Jose, Oakland, San Mateo County, and the SF urban core run on aggressive opening dates dictated by the brand and the landlord, not by the trades.
We compete here on three things: in-house fabrication (no waiting for Bay Area shops to find capacity), self-performed installation (no second-tier subs disappearing mid-project), and a project management team that knows the inspectors in Alameda, Santa Clara, San Mateo, San Francisco, and Contra Costa counties by name.
