'Inclusionary housing' law takes effect in D.C.

A law that makes new or expanded housing developments more affordable for low- to moderate-income residents in the District has gone into effect.

The law requires housing developments consisting of more than 10 units to set aside between 8 and 10 percent to be affordable to residents with low and moderate incomes. The policy, called “inclusionary zoning,” is practiced by hundreds of jurisdictions nationwide, including Montgomery, Fairfax and Arlington counties locally.
