Read the document for the actual space
The NYC Department of Buildings’ certificate-of-occupancy guidance explains that a certificate states legal use or permitted occupancy. Identify the building, floor, and area covered. If the document is temporary, examine its conditions and expiration rather than treating it as a permanent sign-off for every space in the project.
For older premises, a missing certificate is not by itself the complete answer. The agency guidance describes an exception for qualifying pre-1938 buildings and a process for obtaining evidence of lawful use where appropriate. Counsel and the design professional should evaluate the actual history, including later alterations, rather than assuming either universal legality or universal illegality.
Compare the approved condition with the intended operation
A plan for a quiet showroom may differ from one involving classes, food preparation, or large gatherings. Explain the activities, expected occupancy, equipment, and changes to exits or layout. Ask what additional review or work may be needed before the proposed operation can begin.
Keep zoning analysis separate. A certificate’s description does not remove the need to evaluate applicable zoning rules, and a zoning conclusion does not complete every building or operating approval. Likewise, permission to perform construction is not the same milestone as permission to occupy the completed space for the intended activity.
Translate readiness into lease language
A delivery clause should identify the condition the landlord promises, the evidence of completion, and the work left to the tenant. Compare possession, access for fit-out, rent commencement, and opening obligations. Those events may occur at different times and should not be treated as interchangeable merely because the parties use the word delivery.
General Obligations Law § 5-703 contains writing requirements for leases longer than one year. Document material negotiated commitments through the appropriate written agreement. An oral assurance that the landlord will handle approvals may leave unresolved which approvals, by when, and what happens if they are delayed.
Plan for an unmet condition
Suppose the tenant receives keys for construction access while a required occupancy milestone remains unfinished. Decide in advance whether rent starts, whether the opening obligation is extended, and what notice or outside date applies. The answer depends on the negotiated terms and applicable law, not simply on whether the tenant physically has keys.
Before scheduling staff and customer appointments, request the agreed completion evidence and identify any outstanding conditions. Have the relevant professionals address discrepancies between the premises, plans, records, and contract. The goal is a defined path to opening, supported by documents that match the actual space and proposed use.
