KLAMATH FALLS, Ore. – Developers are suing the contractors over an apartment complex. The Crestview Commons Apartments were built in 2003, and by 2009 owners had discovered water damage, rot, and mold, and the tenants had to move out while the repairs were made. Court records show Crestview Commons LP filed suit against Tri-Vest LLC, the main contractor out of Turner, OR, and nine subcontractors. Five of them are from Klamath Falls. A trial is set for October 1.
