The City of Seattle is investing more than $75 million to build and preserve more than 1,000 affordable housing units. 

The city will build 10 new buildings comprised of 1,197 apartments and preserve nine buildings, which include 238 affordable apartments. 

It will be the largest number of affordable homes created in one year in the city, according to Mayor Jenny Durkan's office. 

"The funds invested through the city's Office of Housing will provide affordable homes through a broad range of housing types to meet the unique needs of low-income resident," the city announced in a statement. 

The investment is part of the city's effort to open nearly 4,000 affordable homes by 2022.

"Together with funds I announced last year we will move forward with over $680 million in new affordable homes. Our City is delivering on our commitment to advance public health, create more affordable housing, and make Seattle a more affordable place to live,” said Mayor Durkan. “Too many long-time Seattle residents are getting priced out and pushed out of Seattle. We need to urgently increase the amount of affordable housing to stop the huge displacement of people and provide permanent housing for people experiencing homelessness.”

A federal report released Monday showed there were 552,800 people without homes across the country. That number is up by about 2,000 from 2017, according to the U.S. Department of Housing and Urban Development's January point-in-time tally. It was the second consecutive increase after seven straight years of declines.

While the number of people experiencing homelessness increased across the county, the number of people living on the streets in Los Angeles and San Diego, two epicenters of the homelessness crisis, fell in 2018. The decrease suggests possible success in those cities’ efforts to combat homelessness.

Last year Los Angeles voters approved $1.2 billion to build 10,000 affordable housing units over a decade. Officials also ramped up outreach efforts to connect homeless people with services. January’s point-in-time count found just under 50,000 homeless people in Los Angeles, with three-quarters of them unsheltered.

Seattle / King County has the nation’s largest homeless population outside of New York or Los Angeles, according to the federal report.

King County's homeless count rose to more than 12,000 with more than half of them unsheltered. Four years ago that number was less than 9,000.
