Owners hear "the rent-stabilized tenant finally moved out" and, understandably, their first instinct is relief — a chance to reset the rent, refresh the unit, and start clean. That instinct is out of date. Before 2019, a vacancy really could mean an opportunity to raise the rent significantly or, in some cases, move the unit out of stabilization entirely. The Housing Stability and Tenant Protection Act of 2019 (HSTPA) rewrote that playbook. Today, a vacancy in a rent-stabilized unit is a compliance event with a specific, fairly mechanical set of steps — not a reset button.
Getting this wrong is one of the more expensive mistakes a Brooklyn landlord can make, because the exposure (an overcharge claim on the new tenant's rent) can sit quietly for years before it surfaces. Here's exactly what happens — and what you're required to do — when a rent-stabilized tenant vacates.
The unit stays stabilized. Full stop.
The single most important fact to internalize: a rent-stabilized apartment does not become market-rate just because the tenant left. Pre-2019 law allowed "high-rent vacancy deregulation" (and, separately, "high-income deregulation" for certain long-term tenants). HSTPA eliminated both. There is no rent threshold, no vacancy trigger, and no tenant-income test that pulls a stabilized unit out of regulation today.
If the building was subject to stabilization when the outgoing tenant lived there — because of unit count and building age, or a 421-a or J-51 benefit — it's subject to stabilization for the next tenant too. For the full mechanics of how a unit becomes and stays stabilized in the first place, see our companion guide, NYC Rent Stabilization: A Guide for Landlords.
Step 1: Confirm there's no succession claim before you call it "vacant"
Before you do anything else, verify that the apartment is actually vacant in the legal sense. If the named tenant passed away, entered a nursing facility, or otherwise stopped occupying the unit, a qualifying family member who lived with them as their primary residence — generally for two years, or one year for seniors and people with disabilities — may hold a succession right to take over the stabilized tenancy at the existing legal rent. That person is not a "new applicant" you get to screen and re-rent to at will; they're the next stabilized tenant of record if they qualify.
Skipping this check and marketing the apartment as available while a lawful successor is still living there is a serious misstep that can escalate into an illegal-lockout or harassment claim. Confirm occupancy and succession status first, in writing, ideally with legal input if there's any ambiguity.
Step 2: Know the rent you're allowed to charge
Once you've confirmed the unit is genuinely vacant, the next question is the legal rent for the new tenant. This is where the biggest post-HSTPA change lives.
| Pre-HSTPA (before June 2019) | Post-HSTPA (today) | |
|---|---|---|
| Vacancy bonus | Automatic percentage increase allowed on turnover | Eliminated — no automatic bump for turning the unit |
| High-rent deregulation | Units above a rent threshold could exit stabilization on vacancy | Eliminated — no deregulation path on vacancy |
| Rent charged to new tenant | Legal rent + vacancy bonus + often a market push | The prior legal regulated rent, plus only documented, formula-based increases |
| IAI increases | Larger, often permanent | Capped, temporary, tightly documented |
In practice: the rent you can charge the incoming tenant is the legal regulated rent on file — the same number the outgoing tenant's rent was built from, including whatever guideline increases had accumulated over that tenancy. If the outgoing tenant had a preferential rent below the legal rent, you generally have the option to offer the new tenant the legal rent or continue the preferential rent — but whichever figure you actually charge has to be registered accurately. You cannot simply price the unit at whatever the neighborhood's free-market comps suggest.
Step 3: Individual Apartment Improvements — the legitimate way to add value
Vacancy is, understandably, the moment most owners want to renovate — new kitchen, new bathroom, updated flooring — and it's genuinely the cleanest time to do that work, since there's no tenant to work around. An Individual Apartment Improvement (IAI) can support a rent increase for that work, but HSTPA changed the math substantially: spending is capped, the resulting increase is proportionally smaller than it used to be, the increase is temporary rather than a permanent addition to the legal rent, and DHCR requires real documentation — contracts, invoices, proof of payment — not a verbal estimate. Renovate with a real budget and a compliance plan, not an assumption that the improvement pays for itself in higher rent alone. This is exactly the kind of project our renovation oversight work is built around.
Step 4: Register the new tenancy with DHCR
A change in tenant is precisely the kind of event your annual DHCR registration needs to capture accurately: the new tenant's name, the lease start date and term, and the rent you're actually charging. If you've also filed an IAI, the registration should reflect that increase correctly and on the right timeline. For the step-by-step mechanics, see our DHCR registration guide. Lapsed or inaccurate registration doesn't just risk a fine — it can block you from collecting future guideline increases and undermines your position if the new tenant (or a later one) ever files an overcharge complaint.
Step 5: Re-rent the unit — and screen every applicant the same way
With the legal rent set and the unit ready, you're back to ordinary leasing — with one legal guardrail every Brooklyn owner needs to internalize. Under the NYC Human Rights Law, source-of-income discrimination is illegal. You cannot decline an applicant because they intend to pay all or part of the rent with a housing voucher — Section 8 (Housing Choice Voucher, administered by NYCHA), CityFHEPS or FHEPS, or HASA (all administered by NYC's HRA/DSS). A vacated stabilized unit is, in fact, one of the most common places a voucher tenancy begins, since legal regulated rents in older Brooklyn buildings often line up well with voucher payment standards.
That doesn't mean skipping screening — it means screening consistently. Evaluate income (including the voucher's contribution) against the tenant's actual share of rent, run the same credit and background review you'd run on any applicant, and document your criteria so they're applied evenly. If you're re-renting to a voucher holder, our Section 8 voucher management, CityFHEPS voucher management, and broader government housing programs services handle the program-specific paperwork — HAP contracts, inspections, recertifications — alongside the stabilization compliance above, so the two systems work together instead of tripping over each other.
The mistakes that show up again and again
- Treating vacancy as a deregulation event. It isn't, full stop, post-HSTPA.
- Adding a vacancy bonus out of habit. That increase no longer exists.
- Skipping the succession check. The "vacant" unit may legally still be occupied by a qualifying family member.
- Guessing at the legal rent instead of pulling the actual DHCR-registered figure.
- Renovating on a pre-2019 IAI budget and being surprised the recovery is smaller and temporary.
- Declining a voucher applicant — a source-of-income violation that can trigger a Human Rights Law complaint on top of everything else.
The bottom line
A rent-stabilized vacancy is a compliance checklist, not a reset. Confirm there's no succession claim, price the unit at the legal regulated rent (plus only legitimate, documented increases), register the new tenancy correctly with DHCR, and screen every applicant — voucher or not — on the same fair criteria. Owners who treat vacancy this way turn over units cleanly and keep their rent rolls defensible for years; owners who don't often discover the problem only when a new tenant files an overcharge complaint down the line.
This exact sequence — succession checks, legal-rent verification, DHCR registration, and voucher-ready re-leasing — is what we manage day in and day out across Bed-Stuy, Crown Heights, and the rest of Brooklyn, and it's why we typically re-lease turned-over units in under seven days without cutting a single compliance corner.
