Jobsite thefts nearly doubled between 2024 and 2025, according to a recent joint industry report by job site security and response firms TrueLook and Noonlight.

In 2025, there were 2,639 break-ins at active commercial construction sites across the U.S., nearly double the number in 2024 (1750).

There have been 800-plus reported break-ins across the U.S. already this year.

Data analysis shows that the crimes are predictable, with more than 40% occurring over the weekends, and the peak window is overnight, between 11 pm and 3 am.

The report also found seasonal spikes. April break-ins rise, likely due to warmer weather and longer daylight hours. Peak construction season between July and December also leads to a rise in jobsite theft.

Thieves are targeting Conex boxes and storage containers in laydown areas with staged materials like copper wire, lumber, and roofing supplies. Heavy equipment with keys left inside is also commonly targeted.

Generators, temporary power equipment, and tools round out their wishlist.

Data showed the most common entry method was a truck entering the job site. “Unlocked or unsecured gates are the most common enabler of construction site theft,” the report noted.

But perimeter fencing alone isn’t a deterrent, the report warns.

“The sites that hold up best are those where physical controls, such as gates, locks, and lighting, are combined with cameras with strobes, sirens, and active monitoring that creates a real-time response capability,” the report added.

Insider theft is another area of rising concern. TrueLook indicated the most common occurrence that their monitoring teams regularly flag is after-hours activity by credentialed workers.

The company provided some tips to reduce insider theft, including detailed logging of all after-hours access with supervision and the use of cameras to cover material staging areas.

Of the 170,000 alarms monitored, 2,000 led to police calls, with 29% deemed to be false alarms caused by routine employee activity.

Some other tips to keep jobsites safe include improving lighting, like motion-activated strobe lighting to deter thieves, gate checks at the close of every shift, adding steel hasps and puck locks to Conex boxes, and removing keys from heavy equipment.

In addition, the jobsite security and monitoring experts suggest adding a monitoring team to address alarm triggers, potentially talking thieves out of the crime.
