With nearly 14,000 affordable housing covenants set to expire by 2020, and 1,000 new residents moving to Washington, D.C., each month, the city’s “Housing Preservation Strike Force” released a set of recommendations Wednesday for preserving the district’s existing affordable housing. That includes the ambitious goal of maintaining as affordable 100 percent of units currently receiving federal or city subsidy.

The committee — made up of 18 members from city agencies, law firms, community organizations and the D.C. council — also recommended creating a Preservation Unit within city government to focus on the issue and a public-private preservation fund to leverage outside investment. Other programs would focus on renovating small buildings, providing rental assistance to allow seniors to age in place, and allowing the district to transfer ownership of properties at risk of losing their affordable units to developers who agree to maintain affordability. Regulations for the latter program will be proposed this fall.

With D.C.’s low-cost units dropping precipitously, the strike force recommended all suggestions be implemented immediately. According to the D.C. Office of Planning, between 2009 and 2014, almost 9,500 rental units became unaffordable to households earning 60 percent or less of area median income. During that same period, the overall number of rental units in the district increased by 30,000. That means even as housing production boomed, affordable units decreased by 11 percent.

The crux of the recommendations is the Preservation Unit, which would monitor opportunities to maintain subsidized or naturally affordable units within reach of low-income households. The agency would collect data on existing rentals across the city and monitor the Tenant Opportunity to Purchase Act, which gives renters the right to buy the properties where they reside through tenant associations. Staffing the unit will begin in 2017.
