We track 139 datacenter sites in California, deduplicated from 176 building permits and public facility records. Of those, 129 are operational and 5 are under construction. Facility directories report different totals because they count colocation suites and carrier hotels differently, so treat this as what we can evidence from public records rather than a definitive census.
5 sites in California have permits indicating construction is under way, and the permits that disclose a value total $11.9M. Because this comes from building permits rather than press releases, it reflects work that has actually been filed with a local authority.
60 named operators appear in California, including Vantage Data Centers, NTT, Centersquare, VPLS, CoreSite, Digital Realty, Equinix, 60 Fed LLC. 64% of sites nationally name an operator; the rest are permits filed by an LLC or contractor we could not resolve to a parent company.
