New York Sublet Laws: The Registration Rule Most Guides Miss
Back to the NYC Real Estate Blog
NYC sublet laws run on two tracks: NY Real Property Law §226-b gives most rental tenants a statutory right to sublet with landlord consent, while short-term sublets under 30 days now require registration with the NYC Office of Special Enforcement under Local Law 18. Penalties for skipping registration run $1,000 to $7,500 per incident.
One statute covers consent; another covers how long.
What actually governs a legal rpl 226-b sublet in NYC
For most rental tenants in buildings of four or more units, NY Real Property Law §226-b sets the process. You request consent in writing. Your landlord has 10 days to request more information about your proposed subtenant, then 30 days to approve or deny the sublet.
“If the landlord fails to respond to the sublet request within 30 days, then a failure to respond is deemed consent,” per the NYC Rent Guidelines Board’s own FAQ. That’s the statutory baseline for an ordinary sublet lasting more than 30 days.
Rent-stabilized and rent-controlled tenants are subject to a different, more specific set of rules. The NYS Rent Stabilization Code caps a sublet at two years within a four-year lookback, and requires you to maintain primary residence during that period. It also caps any furnished-unit surcharge your landlord can charge; the RGB confirms “a prime tenant is permitted to charge up to an additional 10%… if the unit is fully furnished.” Those protections hold regardless of a building’s house rules, which matters if you live in a co-op; our co-op sublet guide covers that intersection.
The local law 18 short-term rental registration rule, and the illegal sublet NYC penalty
The fine was never really the point anymore. Under Local Law 18, any stay under 30 consecutive days now requires registering with the NYC Office of Special Enforcement first. The host must also actually reside in the unit, and stays are capped at two guests at a time.
That registration requirement, not just the underlying fine, is the operative enforcement mechanism today. The city also maintains a Prohibited Buildings List where short-term rentals aren’t allowed at all. It reportedly covers close to 14,000 buildings as of a recent count.
Skip registration, and you’re looking at real penalties, reported in the $1,000 to $7,500 per-incident range depending on the violation. Beyond the fine itself, a non-primary-residence short-term rental pattern can also expose a tenant to eviction risk in some circumstances. Treat registration as the real floor here, not an optional step.
| Sublet type | Governing framework | Key requirement |
|---|---|---|
| Standard sublet (30+ days) | RPL §226-b | Written consent request, 30-day landlord response |
| Rent-stabilized sublet | 9 NYCRR §2525.6 | 2-year cap, primary-residence requirement |
| Short-term (under 30 days) | Local Law 18 / OSE | Registration required, host must reside, 2-guest cap |
The rent-stabilized sublet rules tenants keep, no matter what
A right your co-op’s bylaws can’t touch. This is the single most important carve-out in this entire topic. Rent-stabilized and rent-controlled tenants who happen to live in a co-op building keep their statutory sublet rights under the Rent Stabilization Code.
That holds regardless of what the co-op’s own house rules or bylaws say about subletting generally. A board can’t override a statutory tenant protection with a private bylaw.
That’s a narrow situation; most co-op shareholders aren’t rent-stabilized tenants, but it’s worth knowing if it applies to you. The RGB’s own subletting FAQ confirms the 30-day advance certified-mail notice requirement and the 10% furnished-unit surcharge cap. It also confirms specific carve-outs for job relocation, military service, college attendance, and seasonal travel. A landlord who overcharges beyond what’s permitted can face a DHCR complaint carrying treble damages.
Where this law stops applying to co-op shareholders
Read the fine print before you assume it covers you. RPL §226-b applies to a landlord-tenant relationship. An ordinary co-op shareholder, someone who isn’t a rent-stabilized tenant, generally isn’t operating within that framework.
Your ability to sublet instead runs through your proprietary lease and your board’s own approval process, a genuinely different legal mechanism. Our co-op sublet guide covers it in depth.
If you’re weighing a purchase where subletting flexibility matters, or short-term rental income factors into your numbers, don’t assume a building’s rules will let you do what you’re planning. Run the real math with NestApple’s closing costs calculator first. For every other cost and rule beyond the mortgage, our co-op costs and rules hub covers flip tax, special assessments, and tax abatements together. If you’re buying with NestApple, our buyer rebate can offset part of what the purchase costs.
