What each Mandatory Inclusionary Housing option requires, what the income bands mean in monthly rent, and how much extra floor area MIH unlocks in each district.
When MIH is applied to an area, the City selects one or more of these. They differ in how much floor area must be affordable and how deep the affordability goes.
Individual units may range from 40% to 80% of area median income, so long as the weighted average lands at 60%.
Individual units may range from 60% to 115% of area median income, so long as the weighted average lands at 80%.
Individual units may range from 90% to 135% of area median income, so long as the weighted average lands at 115%.
Individual units may range from 20% to 60% of area median income, so long as the weighted average lands at 40%.
Maximum monthly rent by income band and unit size, 2024 schedule for the New York metro area. This is the number that decides whether a project pencils.

The 60% band is highlighted because it is the weighted average both MIH Option 1 and the City of Yes bonus are written around. HUD republishes these annually; this is the 2024 table.
Where MIH is mapped on a lot, these are the floor area figures. Where it is not, the base column governs and this table does not apply.

MIH requires a share of new residential floor area to be permanently affordable in areas the City has mapped for it, almost always alongside a rezoning. Unlike a voluntary bonus, it is a condition of building at the higher density rather than an option.
It is mapped property by property, in Appendix F of the Zoning Resolution, so it is not a district-wide answer. A lot in an MIH area carries the obligation; an identical lot in the same district a block away may not. The district figures below are what MIH unlocks where it is mapped, not a statement that it applies.
The rent limits follow area median income bands published by HUD for the New York metro area. The table below is the 2024 schedule, which is what the engine applies. HUD republishes annually, so check the vintage before relying on a figure in a model.
MIH is mapped and mandatory where it applies, and sets the affordability condition for a rezoning. The Universal Affordability Preference is a citywide as-of-right bonus introduced in December 2024. They are separate mechanisms with different triggers, and on a given lot either, both or neither may be in play.
MIH options and bonus floor area from the inclusionary housing rule set in the Envelope engine, ZR 27-131. Rent limits are the HUD 2024 schedule for the New York metro area. See also the City of Yes calculator.
