The apparently illegal demolition of two of San Francisco’s few remaining earthquake shacks has been stopped by city building inspectors, but not before they had been reduced to the roofs and some framing.

The historic structures, at 369 Valley St. on a steep block of Noe Valley, have been at the root of preservationist and neighborhood fights against a residential developer for more than 10 years.  According to neighbors, a building permit had been issued that required preservation of the two shacks, which were joined to form one cottage, while a single-family home behind the two shacks was approved for demolition and reconstruction. But that permit allowed only for the shacks to be lifted and moved forward on the lot, not the near-total demolition that happened before the project was red-tagged late last week.

Neighborhood preservationists who are organized enough to have a website called savetheshack.net are demanding that the shacks be reassembled using as much of the historic debris that was left on-site in the demolition as possible.

“After a 10-year struggle to preserve the cottages, we now see that our worst fears may be coming true, that the cottages may be destroyed,” said Marc Norton, a retired hotel worker who has lived across the fence from the shacks since 1984. “We always feared that the developer would destroy the cottages in the process of development and act like it was an accident. It looks like that is what happened.”

Norton said the original developer, John Schrader, who saw the project through to the permit stage, recently sold it. The new owner is not adhering to the agreed upon plan to conserve the shacks as part of the development. The violation notice posted by the Department of Building Inspection states that work is being done “that is beyond the scope of the permit.”

After the stoppage, Norton emailed Kelly Wong, enforcement officer for the planning staff, stating that “the only proper course of action is a thorough reassembly of the historic resource. Without such reassembly there is an environmental impact that cannot be mitigated.” 

The two shacks in question have been empty since the property sold in 2014. They are set back to the rear of the lot and pinned between taller residential buildings on both sides. The building at the back of the lot was unpermitted construction and was already demolished by the developer, Benjamin Steiner.  From Norton’s property, he can see the weather vane of a rooster, though that is about all that is still standing.

But the rubble from demolition is just as important.

“The debris is essential to any reassembly of the cottages,” Norton said. “We are demanding that the planning staff order the developer to leave everything as is, until a plan can be made to reassemble the cottages, under the supervision of a qualified preservation architect.”

On Friday, a next door neighbor sent photos to planning staff, complaining that the shacks were being destroyed. Agents from the Department of Building Inspection were sent out to stop work. 

The developer, Benjamin Steiner, did not respond to requests for comment Sunday. San Francisco Supervisor Rafael Mandelman, who represents the district, also did not respond to a request for comment.

Jane Cryan, a preservationist known as the Cottage Lady, estimates there are now fewer than 20 earthquake cottages left in the city out of 5,610 built in the aftermath of the 1906 earthquake and fire. She took a census in 1983 and has been fighting for the dwindling supply, even after she was priced out of the city and living in Oshkosh, Wis.

Cryan said the cottage at 369 Valley was made up of two shacks, one 10 by 14 feet and the other 14 by 18, and they were attached, as was the norm. Cryan, who has written two books on the shacks, said they were most likely hauled out of their original quake refugee camps in Precita Park and dragged up onto the 369 Valley by their owner, as was allowed once the camps closed in 1908. The third structure in the compound was built to mimic an earthquake shack but was not historic, and that’s why it was allowed to be demolished previously, she said. 

“A whole lot of people became homeowners because of these shacks being built with the idea that people who paid $2 installments on them could take them to a lot and join two or three of them together and make a cottage out of them,” said Cryan, who lived in a cluster of three shacks in the Sunset District and was able to get them declared a city landmark. Cryan said a survey mounted in 2015 identified only 43 quake cottages in the city, with two sets in Noe Valley.

“Earhquake shacks were the greatest act of charity the world has ever known, and they’ve been mowed down by developers,” she said. “They are very endangered, and it is a terrible thing the city allowed to happen in Noe Valley.”
