SAN FRANCISCO (Reuters) - Zander Dejah, 25, pays $1,900 a month rent to live in a downtown San Francisco house with at least 40 other people, many of whom sleep in bunk beds.

Houses like The Negev, located in a neighborhood known as “SoMa” or South of Market, have cropped up around San Francisco as an influx of young professionals, many of whom are tech workers, have faced the city’s notoriously high rents and apartment shortages. It has three floors and roughly 50 rooms, filled with bunk beds, beer bottles and laptops, according to residents.

Dejah, born and raised in New York, graduated last year with a degree in computer science and math from McGill University. Unemployed, he moved to California six months ago and found his room at The Negev on Craigslist.

“I thought New York was expensive,” said Dejah, who quickly landed a job as a virtual reality engineer at consulting firm moBack. “It’s basically an extension of college. We sort of live in a frat house.”

The home is certainly filled with parties on weekends, but the residents make sure to sit down every Sunday for a communal dinner, akin to a traditional family gathering.

While some say communal housing provides a solution for many first-time workers fresh out of college, such housing also has created its share of controversy. Housing advocates have complained that this new dorm-like style of living has pushed up rents and forced longtime residents to move out.

Alon Gutman, who co-founded a company called The Negev and began leasing the building on Sixth street in 2014, said, “We have never made somebody move out of that building,” adding that his tenants pay 30 percent to 50 percent less than others in the neighborhood.

“We are trying to solve the housing crisis and increase density in a positive way.”

The Negev company runs nine communal properties, three of which are in San Francisco. The others are in Austin, Texas, and Oakland, California.

The Negev properties, generally in run-down, low-income neighborhoods, are restructured to accommodate a large number of tenants, Gutman explained.

Sarah Sherburn-Zimmer, executive director of the Housing Rights Committee of San Francisco, said housing problems have arisen because occupants leave buildings being converted to communal homes and cannot afford to move back in or the space is no longer suitable for them.

“The Negev house takes affordable housing and makes it unaffordable,” said Sherburn-Zimmer. “All they’ve done is take away housing from people who had it and loved it and pushed them out to make a quick buck.”

Kumar Srikantappa, 31, who also pays $1,900 a month for a single room at The Negev, said he chose the house because of the social experience. After eight months there, the software engineer for Oracle Corp said he would soon be ready to live elsewhere.

“I met a bunch of friends, and I just want to move on to another location and into a bigger place,” he said. “It’s time.”
