OPINION OF THE COURT
Defendant, Presbyterian Hospital in the City of New York, is the owner of property located at 507 West 166th
The issue is whether defendant’s acceptance of rent during the term with knowledge of plaintiff’s violations and without terminating the lease, assuming plaintiff had violated its terms, constituted a waiver of the violations as a matter of law and thus enabled plaintiff not only to remain in possession during the lease term but also to exercise the option to renew. Plaintiff contends that it did and that its actions were legally effective to “prolong” the lease for the renewal terms (see Atkin’s Waste Materials v May,
There should be a reversal. On the record before us whether or not plaintiff violated the terms of the lease and, if so, whether it cured the violations in accordance with the 15-day requirement of the lease thereby enabling it to exercise its renewal option, are questions of fact. Defendant has not waived the violations, if such they were, and the Appellate Division erred in holding as a matter of law that it did.
A waiver is the voluntary abandonment or relinquishment of a known right. It is essentially a matter of intent which must be proved (Alsens Amer. Portland Cement Works v Degnon Contr. Co.,
Its language is clear and unambiguous. The parties having mutually assented to its terms, the clause should be enforced to preclude a finding of waiver of the conditions precedent to renewal (see Matter of Wil-Low Cafeterias v 650 Madison Ave. Corp., 95 F2d 306, cert den
Nor should the intent to waive be inferred from acceptance of rent during the period of the “Yellowstone” injunction. The broad restraint of that order foreclosed defendant after July 30, 1981 from taking any steps to terminate the
Our decision in Atkin’s Waste Materials v May (
Our decision applied the settled principle that acceptance of rent by a landlord from a tenant with knowledge of the tenant’s violation of the terms of the lease normally results in a waiver of the violation (see Woollard v Schaffer Stores Co.,
Plaintiff contends that application of this principle entitled it not only to remain in possession but to renew the lease. The general rule is that if a tenant’s right to renew is conditional, as it is in this case, it cannot be exercised validly unless the tenant is in full compliance with the conditions (see McIntosh v Rector of St. Phillip’s Church,
In Atkin’s Waste Materials v May (supra), the city had knowledge of the tenant’s violations but had not promptly rejected the notice to renew or demanded correction of
Accordingly, the order of the Appellate Division should be reversed, with costs, and the order of Supreme Court, New York County, denying plaintiff’s motion for summary judgment reinstated.
Chief Judge Cooke and Judges Jasen, Jones, Wachtler, Meyer and Kaye concur.
Order reversed, etc.
