D.C. Mayor Muriel Bowser is calling on the D.C. Council and every city housing agency to line up behind her goal to build thousands of new housing units over the next five years.

At her administration’s “New Year, New Housing” event Friday, the mayor made it clear she expects lawmakers and every agency with a hand in housing to do their part to build 36,000 additional homes citywide by 2025.

“This is our affordable housing goal,” Bowser said, addressing a standing-room-only audience of developers, city officials, housing advocates and others at the D.C. Housing Finance Agency’s newly christened Todd A. Lee Auditorium. “You’ve got to be with me on this.”

Speakers at the event — mostly administration officials — reiterated steps the Bowser administration has taken to reduce barriers to home construction and promote affordable housing across the District. Those steps include proposing changes to the city’s Inclusionary Zoning program, revising the Comprehensive Plan, increasing funding for the Housing Production Trust Fund, creating the Affordable Housing Preservation Fund and pushing for affordable housing on city-owned land slated for redevelopment.

Officials at the event acknowledged that the housing target is ambitious. According to John Falcicchio, Bowser’s interim deputy mayor for planning and economic development, the city added 37,000 homes between 2004 and 2018 — taking 14 years to do what officials now hope to accomplish in five.

“We’re going to double our pace of production,” Falcicchio said.

But there are obstacles standing in Bowser’s way. Some are within her own administration.

Developers have long complained about the time it takes for the city to marshal funding for affordable housing projects — a bureaucratic problem the mayor has pledged to address. Externally, she faces resistance from activists and residents who fight development through appeals. And perhaps her most formidable challenge stems from councilmembers unwilling to rubber-stamp her funding priorities, including her failed proposal to create a $20 million Workforce Housing Fund to finance homes affordable to middle-income residents.

The mayor recently raised eyebrows when she called out “enemies of economic development” on the Council. She declined to identify who those councilmembers are. She’s also put opponents to housing development in her crosshairs, saying they should be made to “look shameful.”

Despite her bold housing goals, Bowser continues to attract scrutiny from residents and lawmakers who say she’s not doing enough to create homes for very low-income residents. At-large Councilmembers Anita Bonds and Elissa Silverman recently questioned a Bowser-supported deal to redevelop the D.C. Housing Authority headquarters, saying it doesn’t include enough deeply affordable units. During Bowser’s speech Friday morning, an audience member shouted from the back of the auditorium, “Tell them how many people are being displaced from affordable housing.”

Bowser did not appear to hear the outburst and continued with her prepared remarks.

City officials plan to host a series of budget engagement forums in February, where residents will be invited to submit recommendations for the District’s 2021 budget. The mayor is expected to call for increases to housing funding, though with six seats on the Council up for election this year, it’s not yet clear how much support she’ll find ahead of her likely re-election campaign.
