Direct answer: When your building sells, your lease and your rights come with it. The new owner steps into the old landlord's shoes — they must honor your lease to the end of its term, can't raise your rent mid-lease, and if you're rent-stabilized, must keep offering regulated renewals at Rent Guidelines Board rates. A sale doesn't cancel your lease, reset your rent, or let anyone evict you just because the deed changed hands. What can change is enforcement: some new owners are stricter, and a few try tactics to push long-term stabilized tenants out. Knowing the difference between what's legal and what's just pressure is the whole game.
What legally carries over
A sale is a change of landlord, not a change of your tenancy. Your signed lease stays valid through its term under the new owner, same rent, same terms. Sign a one-year lease in June, building sells in October — that lease runs until the following June, untouched. If you're rent-stabilized, everything continues (renewal rights, capped increases, the rider), because those protections attach to the apartment, not to whoever owns it.
You're also entitled to be told about the change. The new owner should notify you in writing — name, contact info, where to send rent now, who holds your security deposit, and whether management changed. Until you get that in writing, keep paying rent on your existing terms, but confirm in writing who the rightful recipient is before you redirect a single payment.
The security-deposit handoff
Your security deposit is supposed to transfer to the new owner. Get written confirmation that it did — from both sides. If it slips through the cracks during the sale, you can end up chasing two owners to recover it later. In buildings with six or more units, it must sit in an interest-bearing account, and that obligation transfers too.
The tactics to watch for
Most sales are uneventful. But when a new owner wants to raise the building's income and your stabilized rent is in the way, some reach for a familiar playbook. None of it changes your legal status — it's pressure, not law:
- Aggressive lease enforcement — minor things like clutter or a home office suddenly become "violations." (For the record, you're generally allowed to use a reasonable part of your apartment as a home office.)
- Surveillance of common areas, building a case that the unit isn't your primary home.
- Residency monitoring — checking whether you actually live there the required part of the year.
- Construction as harassment — projects that make daily life miserable enough that you leave on your own.
In practice, the single most useful move after a sale is the least dramatic one: verify who actually owns the building before you change where your rent goes. The most important thing: in New York, whatever a new owner claims, they can't remove you without going to court. An eviction notice demanding you be out by a date is not a court order, and nobody puts your furniture on the street without a judge.
After a sale, check these public records
Don't take anyone's word for who owns the building or where your rent should go. Verify it yourself:
| Record | What it tells you | Where |
|---|---|---|
| Deed | Who actually bought the building | ACRIS |
| Owner + managing agent | Who's legally registered | HPD building registration |
| Recent permits/filings | Whether a renovation or demolition is planned | DOB |
See who actually owns your building today — and how many others they control. Weverit identifies the current registered owner for 9,973 of its 10,088 NYC building reports, and shows how many other buildings that same owner controls — so you can see whether you're dealing with a one-building landlord or a large portfolio operator. It also pulls in HPD complaint history (9,972 buildings) and open-violation counts. Look up your building → search any NYC building.
Then: gather copies of your lease and all renewals, get the deposit transfer in writing, document every interaction with new management, and — if you're stabilized and sense pressure — consider forming or joining a tenant association. There's real strength in numbers when a building changes hands.
Frequently asked questions
Can a new owner raise my rent or evict me after buying the building? Not mid-lease, and not just because they bought it. Your existing lease binds the new owner through its full term at the same rent. If you're rent-stabilized, they must offer a renewal at Rent Guidelines Board rates and can only refuse for specific legal reasons. A new owner who sends an eviction notice still has to go to court — the notice itself doesn't remove you, and a change of ownership is never, by itself, a legal ground to evict.
How do I know who the new owner is and where to send rent? The new owner must notify you in writing with their name, contact details, where to send rent, and who holds your deposit. You can verify all of it: the deed is on ACRIS and the current owner and managing agent are listed in HPD's building registration. Confirm the new landlord through those records before redirecting any payment, and keep paying under your existing lease terms in the meantime.
What happens to my security deposit when the building is sold? It should transfer to the new owner as part of the sale. Get written confirmation from both sides — the old landlord that they sent it, the new one that they got it — so it doesn't get lost. In buildings with six or more units it must be in an interest-bearing account. If your deposit disappears during a sale, you may have claims against the previous or new owner, so document the handoff carefully.
My new landlord is enforcing rules the old one ignored — is that legal? Stricter enforcement of your actual lease terms is generally allowed; inventing violations to force you out is not. Watch for a pattern: sudden "inspections," clutter complaints, claims you're running a business or that the apartment isn't your primary home, or disruptive construction. Your rent-stabilized status doesn't change because of any of this. Document everything in writing, know you can usually use part of your home as an office, and get legal help if the pressure escalates — free and low-cost tenant representation exists in NYC.
