ELURP and the Fast Track: what they allow, require, and change.

The list is set by rule: 62 RCNY ch. 13, adopted by the City Planning Commission on April 13, 2026 and in effect since May 20, 2026. It ranks community districts by new affordable homes, counted when an HPD start date is matched to a DOB permit, between July 1, 2021 through June 30, 2026, as a share of each district's housing stock, with preservation excluded, and takes the lowest 12. This is the official list. Search any address to see whether its district is on it.

The City publishes two residential ceilings for each lot. The market-rate ceiling is what an owner may build with no affordability requirement. In R6 and above, the higher one is reachable only if the added floor area is permanently affordable (the Universal Affordability Preference, from City of Yes); in R1 through R5 it is a separate allowance for qualifying sites. ELURP's 30% is measured on the higher ceiling. Applying it to the market-rate one, then subtracting the affordable housing, counts the affordability requirement twice.

We rebuilt the zoning ladder from the City's own lot data. It reproduces the Charter Revision Commission's worked example: R6A to R7A computes to 28.5% against the published 28.5%. Only one step up the ladder is allowed, and across R6 and above the average permitted step is 22.8%. Thirty percent is a ceiling, not a typical outcome.

The affordability requirement can materially change the project economics. An ELURP map change generally brings Mandatory Inclusionary Housing to the entire building, not just the added floor area; we model Option 1, 25% of residential floor area at a weighted average of 60% AMI. So the useful comparison is not rezoning against doing nothing. It is rezoning against building under City of Yes today, which needs no vote and no delay.

The owners with the most immediate reason to look at ELURP are the ones already building: a project filed with DOB but not yet permitted could evaluate a one-step rezoning before it builds. We ran every such filing through the modeled rules. Data pulled September 30, 2026.

Most of the gains are small. The step is one rung of the ladder, and MIH generally requires 25% of residential floor area under the modeled option, so a typical site adds a few homes:

40 of these sites, and 123 of the homes, are in the 12 Fast Track districts.

• More than half the screened projects could not be measured. Of 755 filed projects that pass every other screen, 441 filed for more homes than the lot's published capacity allows. That usually means the project spans several tax lots or already uses a bonus, and our capacity figure for it is wrong. We leave those out rather than rank them on a number we know is wrong. The 307 above are out of the 314 we could measure.
• No private residential top-off has yet used ELURP. 4 ELURP applications appear in the City's Zoning Application Portal as of September 22, 2026: two from City agencies and two private commercial overlays. The first approved was the City's own, HPD's 351 Powers Avenue in the Bronx, 84 affordable homes on City land, approved by the City Council on May 20, 2026. Nothing here is a probability of approval, and ELURP can be used once per site per ten years.
• Not every rule is final. The Fast Track method was adopted on April 13, 2026 and took effect May 20, 2026. City Planning held its hearing on proposed ELURP eligibility rules on September 9, 2026. The Commission postponed its September 23, 2026 vote, so they are not yet adopted. Adopted rules take effect 30 days after publication, and until then who can use ELURP may still change. We model Mandatory Inclusionary Housing at Option 1, 25% of residential floor area at a weighted average of 60% AMI; the option mapped in a given rezoning can differ.
• Landmarks, historic districts and large projects are screened out. A project that would need an environmental impact statement falls back to full review, which removes the reason to use ELURP.

Any address in the five boroughs: its modeled ELURP and Fast Track eligibility, the zoning step the rules allow, the affordability it requires, likely constraints, and whether rezoning beats building today.
