The Urban Institute has a neat piece on housing and affordability in the District. The piece includes visualizations and information relating to housing development. It highlights the fact that housing developed in DC over the last decade has, predictably, targeted the higher-income market. One result is a reduced stock of housing affordable for those with very low and extremely low incomes, even as the city's population increases.
The piece concludes that maintaining an inclusive and diverse DC will require support from public policy and public funds. The Housing Production Trust Fund, the DC Local Rent Supplement Program, and DC’s Inclusionary Zoning policy are highlighted. While the piece does not focus on federal policy, we should bear in mind that federal support is also a key part of this picture. Much of DC's affordable housing has federal as well as local support.
