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 Wisconsin is licensed at the state level by the the Wisconsin Department of Safety and Professional Services (DSPS). A legitimate company operating in Janesville holds a Private Detective/Security Agency license, which means it has cleared Wisconsin DSPS'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 Wisconsin, operating without a license is misdemeanor (Wis. Stat. § 440.26(8)). Operating unlicensed, or knowingly employing someone who advertises or works unlicensed as a private detective/security person, is fined $100-$500, imprisoned 3-6 months, or both; conviction also makes the offender ineligible for a license for one year and can trigger revocation or suspension of the employing agency's license.
