Subletting and Lease Assignment in NYC
The Short Answer
New York gives many tenants a statutory right to sublet under RPL §226-b, subject to landlord consent that can't be unreasonably withheld - you just have to follow the procedure. Subletting keeps you on the lease and liable; assignment transfers the lease entirely and needs the landlord's consent (which they can withhold, though that may release you). Stabilized units have anti-profiteering limits: you generally can't charge a subtenant more than your legal rent. And short-term (under 30 days) rentals are effectively banned by NYC Local Law 18, so Airbnb-style subletting is generally illegal and likely violates your lease.
Why This Matters
Subletting is how renters handle real life - a temporary work assignment, a semester abroad, a need to leave before the lease ends - without breaking the lease or eating the full remaining rent. But it only works if you follow the §226-b process and understand that you stay liable. Done wrong (no consent process, or assuming a sublet ends your obligations), it can leave you exposed to your landlord for a subtenant's nonpayment or damage.
It matters even more because of the short-term-rental trap. Renters tempted to list a room or the apartment on Airbnb to cover rent often don't realize that Local Law 18 makes most sub-30-day rentals illegal - exposing them to penalties and lease termination. Knowing the line between lawful subletting and illegal short-term rental keeps a money-saving move from becoming a costly mistake.
The Money Math
- Lawful sublet: if your subtenant pays the rent, your out-of-pocket can drop to roughly $0 while you're away - without breaking the lease. You remain liable as a backstop.
- Stabilized profiteering limit: you generally can't charge a stabilized-unit subtenant more than your legal rent (plus limited allowances). Overcharging can carry penalties and the subtenant can recover the overage.
- Local Law 18 risk: illegal short-term rentals can trigger fines and lease termination - turning a few hundred dollars of "extra income" into a far larger loss.
The lawful path (a proper sublet) protects your finances; the unlawful path (short-term rentals) risks them.
How People Get This Wrong
The first mistake is subletting without the §226-b process - not sending the required written request, or treating the landlord's "no" as final when an unreasonable refusal may not be enforceable.
The second is assuming a sublet transfers liability. It doesn't - you remain responsible to the landlord. Only an approved assignment transfers the lease.
The third is the Airbnb assumption. Renters list their unit short-term to make money, not realizing Local Law 18 makes most sub-30-day rentals illegal and that it likely breaches the lease too.
Where Renters Get Stuck
- Not following the §226-b procedure (certified-mail request, required info).
- Confusing sublet with assignment and their different liability.
- Stabilized profiteering they didn't know was capped.
- Short-term/Airbnb rentals that violate Local Law 18 and the lease.
- Unreasonable refusals they accept without pushing back.
Your Step-by-Step Playbook
- Decide sublet vs assignment: temporary (you may return) → sublet; permanent exit → assignment.
- Follow the §226-b process for a sublet: written request by certified mail with the required information; the landlord may ask for more but can't unreasonably refuse.
- Use a written sublease and collect a deposit; remember you stay liable to the landlord.
- If stabilized, keep the subtenant's rent within your legal rent (plus limited allowances) - don't profiteer.
- For assignment, get the landlord's written consent; understand a withheld consent may release you in some cases.
- Never run a short-term (<30 day) rental - Local Law 18 generally prohibits it and it likely breaches your lease.
- Keep all requests and responses in writing.
Weighing Your Options
| Path | Liability | Consent | Best for |
|---|---|---|---|
| Sublet (§226-b) | You stay liable | Not unreasonably withheld | Temporary move; you may return |
| Assignment | Transfers (if approved) | Landlord can withhold | Permanent exit |
| Stabilized sublet | You stay liable; rent capped | §226-b process | Same, with profiteering limits |
| Short-term (<30 day) rental | - | - | Illegal (Local Law 18) |
The NYC Rules That Apply
- RPL §226-b: statutory sublet right (buildings of four or more units); consent not unreasonably withheld; assignment needs consent.
- Stabilized profiteering limits: can't overcharge a subtenant beyond legal rent (plus limited allowances).
- NYC Local Law 18: registration requirement that effectively bans most sub-30-day rentals where the host isn't present.
- Lease terms: most leases restrict subletting/assignment consistent with (but not beyond) the statute.
Run the Numbers
Sublet cash position:
Your out-of-pocket ≈ $0 if subtenant pays full rent (but you remain liable to the landlord)
Stabilized profiteering limit:
Max sublet rent ≈ your legal rent (+ limited allowances) - overcharging carries penalties
Short-term rental:
Rentals < 30 days (host absent) = generally illegal (Local Law 18) → fines + lease termination risk
Common Mistakes to Avoid
- Skipping the §226-b process.
- Assuming a sublet ends your liability.
- Profiteering on a stabilized sublet.
- Running an illegal short-term rental.
- Accepting an unreasonable refusal without pushing back.
- Not using a written sublease.
The Thing Most People Miss
Subletting in NYC is a genuine right, not a favor - RPL §226-b means a landlord usually can't simply say "no" to a proper request - but it comes with two catches renters routinely miss: you stay on the hook, and the short-term version is illegal. The lawful sublet is a powerful tool: it lets you leave temporarily without breaking the lease or paying for an empty apartment, provided you follow the process and pick a reliable subtenant (since their default becomes your problem). The trap is treating your apartment as Airbnb income - Local Law 18 turns that into fines and a lease-termination risk. Use the statutory right correctly and it protects you; cross into short-term rentals and it does the opposite.
Renter Decision Layer
When this applies to you: any time you need to leave temporarily, share the unit, or are tempted to rent it out.
Red-flag signals:
- A landlord flatly refusing a proper sublet request.
- Pressure to overcharge a stabilized subtenant.
- The temptation to list short-term on Airbnb.
Your quick checklist:
- Chose sublet vs assignment for my situation.
- Followed the §226-b written request process.
- Used a written sublease; collected a deposit.
- (Stabilized) Kept rent within legal limits.
- Avoided any sub-30-day rental (Local Law 18).
What to do next: follow the §226-b process and keep everything in writing; for a permanent exit see Breaking a Lease in NYC, and for sharing see Roommate Rights Under NYC Law.
Quick Questions
Can I sublet my NYC apartment? Often yes - RPL §226-b gives a statutory right (in 4+ unit buildings), and the landlord can't unreasonably refuse if you follow the process.
Does subletting end my responsibility? No - you stay liable to the landlord. Only an approved assignment transfers the lease.
Can I charge my subtenant more than my rent? Not on a stabilized unit - profiteering beyond your legal rent is prohibited and can carry penalties.
Can I list my apartment on Airbnb? Generally no - NYC Local Law 18 bans most rentals under 30 days, and it likely violates your lease.
What if the landlord unreasonably refuses? Consent can't be unreasonably withheld under §226-b; document the request and response and push back.
