Quick answer: 485-x — officially called Affordable Neighborhoods for New Yorkers — is the new NYC property tax exemption program that replaced 421-a in 2024. Developers who include affordable, rent-stabilized apartments in new buildings get a property tax break for 10, 20, 35, or 40 years. For renters, that means a brand-new pipeline of below-market, rent-stabilized apartments is hitting NYC Housing Connect through 2038. This guide explains what 485-x actually does for you as a tenant, what your lease has to look like by law, and exactly how to find one of these apartments before the lottery closes.
What 485-x is, in one paragraph
Section 485-x of the New York State Real Property Tax Law (RPTL § 485-x) was signed into law on April 20, 2024 as part of the state budget. It replaced 421-a, which had expired in June 2022. The City’s Department of Housing Preservation and Development (HPD) finalized the implementing rules — Chapter 63 of Title 28 of the Rules of the City of New York — on December 16, 2024. The deal is simple: a developer building a new apartment building with six or more units can apply for a property tax exemption that runs anywhere from 10 to 40 years, but only if a percentage of the units are reserved as permanently affordable and permanently rent-stabilized. “Permanent” is not a typo. Unlike under 421-a, where affordability protections expired with the tax benefit, 485-x makes the affordable units stay affordable and rent-stabilized forever.
Who runs the program and where the forms live
HPD’s Tax Incentive Programs (TIP) unit administers 485-x. The official program page is at nyc.gov/site/hpd/services-and-information/tax-incentives-485-x.page and every form, workbook, and restrictive declaration template lives there. The HPD program hotline is (212) 863-6603 and the program email is 485-x_anny@hpd.nyc.gov. The two most important documents for developers (worth knowing exist so you can sanity-check a building’s claim that it’s a 485-x property) are the Affordable Neighborhoods for New Yorkers — 485-x Option A & B Application (last updated May 20, 2024) and the 485-x Units Workbook & Affidavits (updated April 30, 2025). Once HPD approves a building, that building gets a docket sequence number you can reference when calling about a specific property.
The four flavors of 485-x: what kind of apartment you’re actually looking at
485-x has four eligibility tracks, and which one your building used decides how many affordable units it has and at what income level. Knowing the option matters because the affordable share — and the AMI band you need to fit into — changes by track.
Option A: Large and Very Large Rental Projects
Buildings with 100 or more units get a 35-year tax break; very large buildings (150+ units) in certain neighborhoods get a 40-year break. The trade for the deeper benefit is stricter affordability: at least 25% of the units must be income-restricted, and in the largest “Zone A” and “Zone B” buildings the income average is held at 60% of Area Median Income (AMI). “Zone A” includes essentially all of Manhattan south of 96th Street plus Brooklyn neighborhoods like Williamsburg, Greenpoint, and DUMBO and the Queens neighborhood of Long Island City. “Zone B” picks up parts of central Brooklyn and northwest Queens. In citywide 100-unit-plus buildings outside those zones, the average income cap is 80% of AMI. No more than three income bands are allowed, and the highest band can’t exceed 100% of AMI.
Option B: Modest Rental Projects (6–99 units)
This is most of the buildings that will use 485-x. Buildings with between six and 99 units get the same 35-year benefit but only have to make 20% of units affordable, at an 80% AMI average, with the highest band capped at 100% AMI. If you’re looking at apartments in a newer mid-rise outside the prime Manhattan submarkets, this is the track you’re most likely to encounter.
Option C: Small Rental Projects (6–10 units)
The boutique-building track. Properties with 6 to 10 units, located outside Manhattan, can opt into a shorter 10-year benefit in exchange for permanently rent-stabilizing at least half of the units. There’s no AMI test on Option C buildings — the protection is pure rent stabilization. If you sign a lease in a small new building in Brooklyn, Queens, the Bronx, or Staten Island, ask whether the building took the 485-x Option C exemption. If it did, the unit is rent-stabilized by law.
Option D: Homeownership Projects
The homeownership track is for new condo and co-op buildings with at least six units, outside Manhattan, where the assessed valuation per square foot doesn’t exceed $89/SF on the first assessment after completion. Owners get a 20-year property tax break, but they have to commit in writing to live in the unit as their primary residence for the first five years. This is the only 485-x option that helps owner-occupants directly.
What 485-x actually does for renters: four protections worth knowing
Most renters will never read RPTL § 485-x. But four things in the statute matter directly to anyone living in or applying for one of these units.
1. The affordable unit is permanently rent-stabilized. All Restricted Units — both Affordable Housing Units under any option and the rent-stabilized units under Option C — remain subject to rent stabilization both during and after the tax benefit period. That means your rent can only be increased by whatever the NYC Rent Guidelines Board allows each year (the board sets the percentage each June for leases starting October 1 of that year through September 30 the following year). It also means you have the right to a renewal lease, and the landlord cannot evict you except for cause as defined by the Rent Stabilization Code.
2. Your lease must be one or two years, your choice. Every lease and renewal for a 485-x restricted unit must be for a term of one or two years, at the tenant’s option. If your landlord tries to push you into a longer commitment or a month-to-month, that’s not lawful for a 485-x unit.
3. No second-class status inside the building. The statute requires that all rental units in a 485-x building share the same common entrances and common areas as the market-rate units. Affordable units cannot be segregated to a specific floor or wing — the era of “poor doors” is over for 485-x. If the building has a gym, lounge, package room, roof deck, or laundry, you have the same access on the same terms as any market-rate tenant.
4. Even if HPD revokes the building’s benefits, you stay stabilized. If your eligibility was approved by HPD and you moved in before any later denial or withdrawal of the building’s application, your unit remains subject to rent stabilization until you choose to leave. The protection follows the tenant, not the tax break.
How to find a 485-x apartment
There are three real-world ways tenants get into a 485-x unit. The first is by far the most common.
Path 1: NYC Housing Connect (the lottery)
Almost every new 485-x affordable unit is marketed through the city’s central housing lottery portal, NYC Housing Connect, at housingconnect.nyc.gov. You create one free profile with your household size, income, and current address, and then you apply to individual lottery listings as they post. There is no fee to apply, and there is no limit on how many lotteries you can enter. Each listing tells you which AMI bands the building is offering, the rent at each band, and the application deadline. For a 1-person household in 2026, the standard AMI brackets translate roughly to: 30% AMI maximum income $29,100; 50% AMI max $48,500; 80% AMI max $77,600; 120% AMI max $116,400. The NYC AMI for a family of four is $120,800. The official income guide is published by HPD at a806-housingconnect.nyc.gov/nyclottery/instructionPDFs/Income_Guide_text_en.pdf.
Selection is by random log number, not first-come-first-served, so applying early in the lottery window gives you no advantage. What does matter is being in the right income band, having all your documentation ready when you get the call (pay stubs for the past six months, last two years of tax returns, government ID, and references from current and prior landlords), and being responsive to the marketing agent’s emails. If you miss a deadline to submit documentation, you go back to the bottom of the log pile.
Path 2: Direct application to the building’s marketing agent
Every 485-x building that’s filed an Application Registration form within six months of its Commencement Date has selected a Marketing Monitor — an outside firm HPD has approved to run the lease-up. After the lottery has cleared and the building has placed initial tenants, units sometimes become available between full lottery cycles. The marketing agent will list these on the building’s own website or on Housing Connect as a “re-rental.” The same income rules apply, but you may face a smaller applicant pool.
Path 3: New construction street-level signage and HPD’s project list
HPD publishes a list of all 485-x prospective applicants and approved projects through NYC Open Data. If you want to see whether a specific new building near you took 485-x benefits — or is about to start a lottery — search the dataset 485-x Affordable Neighborhoods for New Yorkers: Registrations of Prospective Applicants for Tax Benefits at data.cityofnewyork.us. The dataset shows the project address, the Commencement Date, and the option the developer is pursuing, which tells you in advance what AMI levels the affordable units will be priced at.
How 485-x is different from 421-a (and why it matters for your rent)
If you’ve been in NYC’s rental market for a while, you’ve heard of 421-a. Many older buildings — the apartment your friend rents in a glassy mid-rise from 2018 — were built under 421-a. The key differences for renters are worth knowing because they explain why some buildings act very differently at the end of their benefit period:
Under 421-a, the affordable units were rent-stabilized only for as long as the building received the tax benefit. When the exemption expired (often after 25 or 35 years), the apartments could be deregulated. Some 421-a buildings are facing that cliff now. Under 485-x, the affordable units are permanently rent-stabilized — they stay rent-stabilized even after the building’s tax break expires. That’s a generational change in tenant protection, and it’s the single biggest reason housing advocates supported the new program despite its lower overall affordability share.
The second big change: 485-x has wage requirements baked into the deal. Construction workers on buildings with 100+ units must earn at least $40/hour, escalating 2.5% per year, and building service employees (porters, doormen, supers) in buildings of 30+ units must earn the prevailing wage. The Comptroller’s office enforces these wages. None of this directly affects your rent, but it does affect who builds your building and who maintains it.
Important deadlines and dates that affect your apartment hunt
The 485-x program is time-limited by statute. Eligible projects must commence construction after June 15, 2022 and on or before June 15, 2034. They must complete construction on or before June 15, 2038. That means the pipeline of new 485-x apartments is finite — every new building that breaks ground after June 15, 2034 cannot use the program. For renters, this matters in two ways: first, the deepest benefits go to projects that start before June 30, 2026, which is creating a near-term construction surge; second, expect lotteries for 485-x buildings to accelerate through 2027–2030 as those projects finish.
Common questions HPD’s hotline gets
Does my landlord have to tell me if my building is a 485-x building? Yes. The lease for a 485-x affordable unit is required to identify the unit as a Restricted Unit. The rent stabilization rider that comes with every stabilized lease is also required.
Can my rent go up by more than the Rent Guidelines Board allows? No. Your unit is rent-stabilized. Increases are limited to whatever the RGB sets each year (the board meets in June and the new rate takes effect for any lease beginning October 1 through September 30 of the following year). The current Rent Guidelines Board rates are posted at rentguidelinesboard.cityofnewyork.us.
What if I think the landlord is overcharging me? File a rent overcharge complaint with the New York State Division of Homes and Community Renewal (HCR). The form is RA-89 and the agency hotline is (718) 739-6400. HCR will pull the rent history and adjudicate.
What if I’m denied at the lottery and I think it was wrong? Each lottery has an appeal process administered by HPD’s Marketing unit. The denial letter explains the appeal deadline, which is typically 10 business days. If you don’t get a denial letter and you should have, contact HPD Marketing through the contact page at nyc.gov/site/hpd/services-and-information/marketing.page.
The bottom line for renters
485-x is a new — and frankly more tenant-friendly — version of the 421-a deal: developers get a multi-decade property tax break in exchange for committing a slice of every new building to permanently affordable, permanently rent-stabilized apartments. For a renter, that means a pipeline of newly built, code-compliant, fully amenity-shared apartments will keep coming online through 2038, at rents pegged to 60%, 80%, or 100% of AMI. The only way into one is to be in the Housing Connect system, in the right income band, and ready to act fast when you get matched. Set up the profile now — even if you’re not ready to move — because you can’t apply to a lottery without it, and the lotteries close fast.
