Guam - Many of the island's commercial building owners are breaking the law and don't even know it.

Even worse, there are no penalties for breaking the local law which states if you put a sign on a building, you need to occupy the space.

Department of Public Works director Carl Dominguez says lawmakers recently held a roundtable with the agency to discuss whether or not the law should be revised. "I think the Guam law goes back decades and the other reason why I wanted to meet with the senator and some people in the community about the sign law was whether we should update the sign law. Whether we should allow these types of advertising and to do so, we'd have to revise the sign law," he explained.

The present law also states that the sign cannot take up more than 10% of the wallspace it's attached to.

Dominguez tells KUAM News should the law be revised, he hopes to include monetary penalties.
