Theft is starting to become a problem at many of the local construction sites.

“In the last month we've had four different job sites broken into,” Mike Moir with Woodhouse Group Real Estate said.

Moir says, in all, they’ve lost about $8,000 in supplies, which ranged from appliances, to tools, to lumber.

“Plywood is a big deal now because it's expensive, it's about $20-$22 a sheet now. So we've had builders lose as much as a hundred sheets on a job site,” Moir said.

The new development in Nampa also had construction trailers broken into and a number of nail guns taken.

“That's out of pocket for these construction workers and it's just shameful that it's happening,” Moir said.

Moir and his developers decided to set up cameras late last week. Over the weekend, the cameras caught a person stealing tools from their job site.

“It is absolutely taking food off these builders' table, and their sub-contractors, and the hourly workers. It effects everybody on a job site,” Moir said.

This particular incident is still under investigation. However, Nampa Police say with all the recent construction, it’s something they’re seeing a lot more of.

“When you have a building boom going like we do in the Treasure Valley, the crimes of opportunity at these building sites are there,” Sgt. Time Riha with the Nampa Police Department said.

There are ways to help protect yourself from these crimes. Police suggest you make sure all of your tools are locked up, as well as identifiable by either engraving them or marking them.

“Usually that success comes when I can identify what the item looks like, if I can say for sure that this is an item that's been stolen. Then I can make a case and I can track these guys down,” Sgt. John Terry with the Boise Police Department said.

Boise Police say their biggest problem is with construction trailers, which is why they suggest a hitch lock.

“If it's stuff that's locked up, it's stuff that’s written on or painted on with a name or number, they'll move on to the next guy because the next guy's not doing it. If it's going to be difficult for them to turn around and sell or get rid of, they'll move on to the next construction site,” Sgt. Terry said.

Police also ask neighbors to be vigilant and if they see something out of the ordinary to call police.
