Assignment & Sublet Clause: NYC Office Leasing, Explained

How the clause works in a New York office lease

Nearly every New York office lease starts from a flat prohibition: no assignment or sublet without the landlord's prior written consent. A negotiated clause carves the flexibility back, saying consent will not be unreasonably withheld, conditioned, or delayed, listing what the landlord may ask about a proposed occupant, and putting a deadline on the answer. A bare consent requirement with no reasonableness standard leaves the decision with the landlord.

Two companion provisions usually travel with it: profit sharing, which gives the landlord a piece of any rent a subtenant pays above your contract rent, and recapture, which lets the landlord take the space back instead of consenting. Together they decide whether the clause is a usable exit or a decorative one.

A worked example at the citywide median

The citywide median asking rent on our book is $75 per square foot per year, so a company holding 1,000 square feet it does not need carries roughly $75,000 a year, about $6,250 a month, for empty desks. Suppose it subleases the surplus. If the market has moved up, the profit-sharing clause decides who keeps the spread, and an unnegotiated form can hand the landlord all of it. If the market has moved down, the shortfall between what the subtenant pays and what you owe stays yours for the remaining term. Either way the sublet reduces the bleeding rather than closing the wound, so consent has to move fast enough that a live subtenant does not walk.

What is negotiable, and where we push

Landlords write the first draft to be improved; on our tenant-side mandates the pressure goes to four places:

• Permitted transfers without consent: affiliates, successors by merger, and a buyer of the business, so a financing round or acquisition never hands the landlord leverage over the company's future.
• The consent standard and the clock: "not unreasonably withheld, conditioned, or delayed", a fixed review window, and silence counting as consent, so a deal cannot die in an inbox.
• Recapture, narrowed: only on a full assignment or a sublet of substantially all the space, exercised once on a short window, with a complete release if the landlord takes the space back.
• Profit sharing, after real costs: any split should apply only to profit net of free rent, commissions, legal fees, and downtime, with an even split after costs a common landing point.

The traps that cost tenants money

The most expensive misunderstanding is believing an assignment ends your liability. On most New York forms the original tenant stays liable for the balance of the term even after assigning, so if the assignee fails years later the landlord can come to you. A full release is hard to win; a burn-off after clean performance by a creditworthy assignee is a realistic ask.

Recapture carries a quieter trap: on some forms the request itself triggers the right, so merely asking to sublet lets the landlord take the space back and re-let it at today's rents. Watch also for profit computed before your costs, uncapped consent fees, and marketing restrictions that bar advertising below the building's asking rents. Each is fixable on paper before signing and nearly impossible after.
