Licensed security system installers in Los Angeles, CA

Q: How many licensed security system installers are in Los Angeles?

524 security system installers hold an active Contractors State License Board (CSLB) or Bureau of Security and Investigative Services (BSIS) licence with a mailing address in Los Angeles, checked on 4 November 2026. 306 of them have been licensed for 10 years or more.

Q: Does a security system installer need a licence in California?

Yes, when the whole job, labour and materials, costs $1,000 or more or needs a permit. Below that, California's minor-work exemption (B&P Code 7048) applies, but only if they work alone.

Q: How do I check a security system installer's licence in Los Angeles?

Ask for the licence number and look it up on the CSLB or BSIS website, or search this page. Every security system installer listed here was matched to an active licence on the CSLB or BSIS register.

Q: Which security system installers rank highest in Los Angeles?

By our published formula (years licensed, complaint record, bond and insurance, and Google reviews), the top three are Security Plus Co (96), Construction Services Unlimited (94), Network Experts Inc (94). Paying or claiming a listing never changes the order.

Q: How much do security system installers charge in Los Angeles?

Security system installers in the Los Angeles-Long Beach-Anaheim metro earn a median $34.41 an hour (BLS, May 2025); contractors typically bill about twice the wage to cover insurance, overhead and profit.

Q: Do I need a lead-safe certified security system installer in Los Angeles?

If your home was built before 1978 and the work disturbs paint, yes: the law requires a firm certified lead-safe by the US Environmental Protection Agency. 69% of homes here were built before 1980 (US Census, ACS 2024 1-year), and 6 of the 524 licensed security system installers listed are certified.
