MIH

Mandatory Inclusionary Housing is New York City's requirement that qualifying new residential floor area in mapped areas include permanently affordable housing. MIH is not citywide: it applies within areas mapped through the public land-use process, catalogued in Appendix F of the Zoning Resolution. Each mapping selects among options from the program's menu — combinations of affordable-share and income-level requirements — so obligations differ between mapped areas.

Inside a mapped area, MIH attaches to actions that create new residential floor area above the program's thresholds, whether by construction, enlargement, or conversion, and the affordability obligation is permanent. Whether a specific lot is MIH-mapped is a parcel-level question, checkable against the mapped boundaries rather than neighborhood intuition.
