How this page is built

Nobody pays to appear on this page, and position cannot be bought. A company is listed only where the official register showed it holding a current license when we checked on September 4, 2026.

  • Ranked by workers' compensation cover and years licensed.
  • Left off anything expired on the date we checked, or carrying any status other than current.
  • Not published at all until at least 3 low voltage companies pass that check. At most 10 appear - a cut through the ranking, not a further test.

The full method, including what each register does and does not publish.

San Mateo County low voltage licensure at a glance

California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 77 active C-7 low voltage systems licenses in San Mateo County, 3 of them registered in San Bruno. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median San Bruno license has been held 33 years, and the longest-standing one dates to 1979. 1 of San Bruno's 3 licenses (33.3%) carries current workers' compensation cover in CSLB's file. That is employee injury cover, not liability insurance, and a blank usually means an owner-operator with no employees - lawful, and not a mark against anyone. The contractor bond is not a signal here: 76 of the county's 77 licenses carry the same $25,000 bond California sets by statute. 8 county licenses reach their expiration date within the next 90 days. CSLB cannot link straight to a license record, so every listing above shows its number for you to type into CSLB's license lookup. How we verify.

Why is a company not on this list?

A company appears only when we can match it to a current record in the register this page is verified against - 3 companies passed that match for San Bruno. A credential that is expired or suspended, or a business we cannot conclusively match to a current record, never appears. A listed business that believes its information is wrong can reach us through the contact and corrections page at homversa.com/contact. How current each date is, and what happens when a credential lapses, are explained on our methodology page.
