Construction site security in San Francisco targets the after-hours theft of tools, copper, equipment and catalytic converters, usually combining a night post with mobile patrol or camera towers.
In San Francisco, demand for construction site security is driven by a dense concentration of corporate and financial headquarters and a downtown retail core under theft pressure. The sectors that most rely on this service include corporate headquarters, financial services, technology, with specific needs in areas such as the Financial District, Union Square and downtown retail, SoMa tech offices. The city's main security concerns — organized retail crime and storefront theft and downtown property crime and open-air issues — make working with a licensed, professional provider a priority investment for businesses and homeowners.

Estimated range per guard post/month in San Francisco:
$10,000 — $16,000 USD
That puts San Francisco about 25% above the US national range ($8,000 — $12,800) — local wage floors, cost of living and competition for licensed officers all push rates up.
Armed officers typically run about 35% more than unarmed coverage for the same post — the premium covers the firearm permit, range requalification and the higher insurance the provider carries. In San Francisco that puts an armed post around $14,000 — $22,000 USD per guard post/month.
Priced like standard guard posts, typically weighted to nights/weekends when theft risk peaks. Many sites combine a night post with mobile patrol or camera monitoring to cut cost.

Before you hire
Construction sites lose an estimated $300M–$1B a year to theft, and an injured trespasser can be a bigger risk than the loss. Here's how to protect a site — guards, patrol, cameras — what it costs, and the attractive-nuisance liability you can't ignore.
Read the construction site security buyer's guidePrivate security in California is licensed at the state level by the California Bureau of Security and Investigative Services (BSIS), Department of Consumer Affairs. A legitimate company operating in San Francisco holds a Private Patrol Operator (PPO) license, which means it has cleared California BSIS's ownership, background-check and insurance requirements. Ask for that license number in writing and verify it yourself — a certificate on the wall tells you nothing about current standing, since a license can be suspended or revoked.
Hiring an unlicensed company is a risk you carry. In California, operating without a license is misdemeanor (Cal. Business & Professions Code §7582.3). Operating as an unlicensed private patrol operator (or knowingly engaging a non-exempt unlicensed one) is a misdemeanor punishable by a $5,000 fine, up to one year in county jail, or both; falsely holding oneself out as licensed (badge, ID/business card, letterhead, or advertising) is a separate misdemeanor with a fine up to $10,000, and a conviction bars BSIS licensure for one year (five years on a second offense).
San Francisco scores 53/100 on our Crime Index (grade D), which makes it safer than 18% of the 759 US cities we track. The index is built from FBI Crime Data Explorer reports for a population of 815,330.
