COOS BAY — Workers from All Pro Restoration of Coos Bay spent Wednesday morning putting plywood over the windows on the first floor of the historic Chandler Hotel building.

All Pro’s owner, Brian Simmons said the northwest corner of the building has dropped 12 inches, though he didn’t know over what time frame. The windows were cracking and the owners were worried they could shatter and spray nearby pedestrians with glass shards, Simmons said.

Concrete has split at the bottom of the building on the northwest corner and cracks have formed there, spreading on the sidewalk toward Second Street. But the building’s owner hasn’t submitted repair plans to the city and Coos Bay officials may need to resort to the same process they used to condemn the Lockhart Building down the street.

City Manager Chuck Freeman said city officials recently walked through the building, but haven’t formally inspected the building or taken any actions.

The owner, Robert Blair of Washington, D.C., has put the building up for sale, Freeman said.

“He is basically hoping the city will help him find a buyer for the building,” he said. “We need to sit down with the owner and see what studies they have done.”

The only windows left uncovered were those to the entrance of the building. Once the last tenants leave, Simmons said, those will be boarded up, too.

Freeman said he hopes the owner will take steps himself to make the repairs. Otherwise the city would use its authority to get the Chandler fixed.

“The building can’t stay in its present condition,” Freeman said.

Blair did not return phone messages.

The hotel was added to the National Register of Historic Places in 1984.

The building’s tenants, who occupied 30 subsidized apartments, learned they would have to find new homes in May, when the owner announced plans to repair the 100-year-old building.

All but one has moved out, said Ned Beman, Coos-Curry Housing Authority executive director. The last tenant is scheduled to leave by Friday.

“Everybody got relocated to where they wanted to live,” he said.

The majority stayed in the downtown area, while others found places to stay with relatives or in other communities.

Once the last tenant leaves, Freeman said the city would take a more proactive approach with the building.

“We want to know what the plan is,” he said.
