Ashland officials are considering whether they should adopt laws requiring owners of historic buildings to make seismic upgrades when they undertake major renovation projects or switch to a higher occupancy use, such as changing a retail shop to a restaurant.

Ashland officials are considering whether they should adopt laws requiring owners of historic buildings to make seismic upgrades when they undertake major renovation projects or switch to a higher occupancy use, such as changing a retail shop to a restaurant.

Many of the charming brick buildings that make up much of Ashland's historic downtown would be severely damaged or destroyed in a major earthquake.

Medford and Portland are among the cities that require seismic upgrades under certain conditions.

Unreinforced brick buildings are common in the historic downtowns of most Southern Oregon cities, including Ashland. They are not supported by metal that would help keep the brickwork in place.

"Old red brick buildings are charming, but they're very vulnerable to earthquake. They will crumble," said city of Ashland building official Michael Grubbs, who is researching potential seismic upgrade requirements for future consideration by the Ashland City Council.

Buildings at risk include Ashland City Hall and most historic downtown buildings, such as those housing Mix Sweet Shop, The Black Sheep Pub & Restaurant, the Elks Lodge and the former Alex's Plaza Restaurant and Bar, Grubbs said.

Ashland Fire & Rescue Chief John Karns said the majority of downtown buildings would not do well in a major earthquake.

Rescuing people in collapsed buildings is a time-consuming process, with rescuers having to shore up structures before they can enter, Karns said.

He said he believes seismic upgrades of at-risk buildings should be mandatory wherever there are employees and patrons.
