New York City has its own rental language. Listings often include terms that sound familiar but mean something very specific in NYC. Misunderstanding these words can lead to wrong expectations, surprise costs, or uncomfortable living situations.
This glossary explains the most common NYC rental terms in clear, practical language.
Walk-up
A building without an elevator. In NYC, a walk-up can have anywhere from three to six (or more) floors. Lower floors are usually more desirable.
Elevator building
A building with at least one elevator. These apartments often cost more and may include additional building fees.
Doorman building
A building with staff at the entrance who assist with security, packages, and guest access. Convenient, but usually higher rent or fees.
Super (Superintendent)
The person responsible for building maintenance and repairs. In NYC, a good super can make a huge difference in quality of life.
Rent-stabilized
An apartment with regulated rent rules that limit how much rent can increase over time. These units often have stronger tenant protections.
Market-rate
An apartment with rent set by the market, not regulation. Rent can change significantly at renewal.
Studio
One open room combining living and sleeping space, with a separate bathroom.
Convertible
An apartment designed so a temporary wall can create an extra room. Often advertised as “1-bed flex” or “2-bed flex.”
Flex wall
A temporary wall added to divide space. Always confirm if it’s allowed by the building.
Railroad apartment
Rooms connected in a straight line, where you pass through one room to reach another. Common in older buildings.
Alcove
A small recessed area, often used for a bed or desk, usually without a door.
Exposed brick
Interior brick walls. Visually appealing, but sometimes colder and harder to insulate.
Gross rent
The full monthly rent before any discounts or concessions.
Net rent
The average monthly rent after incentives (for example, “1 month free”). Always confirm what you actually pay each month.
Security deposit
A refundable deposit, typically equal to one month’s rent, held to cover damages beyond normal wear.
Guarantor
A person or service that agrees to pay the rent if the tenant cannot. Often required for students or newcomers.
Application fee
A fee charged to process your rental application, usually covering background and credit checks.
Heat included
Heating costs are covered by the landlord. This can significantly reduce winter expenses.
Utilities included
Some or all utilities (heat, hot water, gas) are included in the rent.
Laundry in building
Shared laundry facilities located somewhere in the building.
In-unit laundry
Washer and dryer inside the apartment — rare and highly valued in NYC.
Pet-friendly
The building allows pets, often with restrictions or extra fees.
COI (Certificate of Insurance)
Proof of insurance required by some buildings when hiring professional movers.
Move-in window
A specific time slot reserved for moving, often required in elevator buildings.
Amenity fee
An extra charge for access to building features like gyms, lounges, or roof decks.
