The good news: D.C.’s first inclusionary zoning units sold this year! The bad news: That means zero IZ units sold since the regulation went into effect in 2009. The IZ program is the city’s main statutory means of producing affordable housing, requiring developers of large residential buildings to set aside 8 to 10 percent of the units for low-income residents. But the year began with the city facing a lawsuit from the developer of D.C.’s first two IZ units because he couldn’t sell them. Things didn’t get any rosier when an April report revealed that no IZ units had been sold through 2012. Finally, in July, the city triumphantly announced the first sale. Some rental units are occupied, and with the real estate market strong again, the city’s anticipating that more than 1,000 IZ units will be built in the next few years. But this surely isn’t the start the D.C. Council envisioned for the program when it passed in 2007.
