The cost of living in San Francisco is so expensive that families making nearly $120,000 a year qualify for low-income housing, according to a recent report from the U.S. Department of Housing and Urban Development.

A four-person household with an income of as much as $117,400 meet the threshold to qualify for subsidized housing in San Francisco County, as well as in the nearby counties of San Mateo and Marin.

The threshold rose by more than 10 percent over last year, according to HUD's recently released 2018 income thresholds for affordable housing.

The Bay Area counties' threshold tops all others in the nation, the East Bay Times reported.

What is the median income for a family of four in the Bay Area?

The median family income for a family of four in those counties is $118,400, according to the HUD report. Families of four making as much as $73,300 are considered "very low" income and those bringing in $44,000 annually are considered "extremely low" income.

By comparison, the median income for a household of four in Dallas County, Texas, is $77,200 a year, and the threshold for subsidized housing is $39,600.

In Los Angeles, the low-income threshold for family of four is $77,500.

And, in New York City, households of four earning $83,450 a year are eligible to apply for low-income housing, according to the East Bay Times.

How much is apartment rental?

A one-bedroom apartment runs about $2,560 a month and a three-bedroom goes for more than $4,150, according to a recent survey of 2019 Fair Market Rents for San Francisco.

And the median price for a single-family home in the Bay Area broke a record high of $935,000 last year, the East Bay Times reported using data from Core Logic.

What else?

The Bay Area has struggled for several years to find solutions for more affordable housing options.

Federal income limits for affordable and subsidized housing have risen consecutively over the last four years, the report showed.
