DENVER (CBS4) – The city of Denver may take more action against a hoarder living in the 1900 block of Humboldt Street.

Neighbors say the trash has been piling up for years. Now it’s stacked as high as the fences in both the front and back yards. They are also concerned about the health hazard.

The neighbors are also concerned about pets they see inside and two children they believe live in the home.

“I just don’t think we as neighbors should have to look at that,” the neighbor said. “I’m concerned for the children that are living there.”

City Council member Chris Nevitt said the homeowner has been cited several times and issued a series of fines, but neighbors say it’s not helping.

“It’s just an eye sore and someone shouldn’t be living in those conditions and we shouldn’t be forced to have to live near someone like that,” the neighbor said.

The city says if the problem gets worse and the owners continue to ignore fines and orders it could clean up the mess itself and put a lien on the property.
