(dissenting in part). I agree with the majority that the motion by defendant City of New York for an order dismissing the complaint against it should have been granted by Special Term. I also agree that summary judgment was properly granted to defendants Chase Manhattan Bank, N. A., John Hancock Mutual Life Insurance Company and Debevoise & Plimpton. However, I disagree with the result reached by the majority that notice and consent by the plaintiff ground lessee was not required before the defendant fee owner could incorporate the leased property into a single zoning lot and exploit the enlarged development rights attributable to the full tract. This conclusion is inconsistent with the intent of the drafters of *494Zoning Resolution § 12-10 to require notice and agreement among interested parties before a multilot tract can be treated as a single zoning lot.
The majority opinion notes the history of the section and the fact that as it was first promulgated, the Court of Appeals reached the conclusion that the ground lessee (with a total term of not less than 75 years) or the fee owner, whichever acted first, had the right to use the development rights attributable to the lot in connection with the development of a neighboring lot (Newport Assoc, v Solow, 30 NY2d 263, cert denied 410 US 931).
Further problems under section 12-10 resulted from the fact that although the minimum length of term for a lease to qualify as “ownership” was specified, there was no statutory requirement that the lease itself, or a memorandum thereof, be recorded. There was, therefore, no certain way for prospective purchasers or others to determine from the public record whether development rights attributable to one lot had been used in constructing a building on an adjacent site.
In recognition of such problems associated with the original section 12-10, the definition of zoning lot was amended to its current form in 1977. The purpose of the amendment was described by this court in Macmillan, Inc. v Cadillac Fairview Corp. (86 AD2d 15, 19, revd on other grounds sub nom. Macmillan, Inc. v Lex Assoc., 56 NY2d 386): “The limited legislative history suggests that the function of the amendment * * * was to facilitate air rights transfers in a manner which would not derogate from the rights of parties with certain defined substantial interests in the real property affected. The purpose was to involve and bind all such parties to the arrangement (City Planning Comm. Doc. No. N760226ZRY, July 13,1977 Cal. No. 27, p 2, Amendment of the Zoning Resolution).” Thus, under this guiding principle that a zoning lot merger should not be effected without the knowledge and agreement of all interested parties, the drafters of the 1977 amendment devised a statutory scheme under which recognition and protection would be afforded to the holders of interests in the property and notice of prior zoning lots mergers would be a matter of public record for prospective purchasers and others interested in the property.
The draftsmen of section 12-10 created a separate subsection for each of a series of increasingly complex situations which might be involved in a zoning lot designation: subsection (a) deals with the simplest case, an existing single lot of record; subsection (b) deals with the still relatively simple situation of two or more lots which are to be merged into a single zoning lot, *495till of the interests in which are owned by a single owner; subsection (c) deals with the more complex situation where two or more lots are held in single fee ownership, but as to which there are other parties with interests, such as ground leases, affecting all or substantially all of the tract; and, finally, subsection (d) deals with the most complex situation, where the lots to be included in the tract are under either single or multiple fee ownership, but there are entities holding lesser interests, such as ground leases, with respect to different portions of the tract, and such interests do not extend to all or substantially all of the tract. Under a proper reading of section 12-10, which gives meaning and effect to all of its subsections and which carries out the drafters’ intent, the tract at issue cannot qualify as a single zoning lot under any of the provisions of section 12-10, except for subsection (d). It is a fundamental rule of statutory construction that all parts of a statute should be given effect and meaning and harmonized to achieve the legislative purpose (Sanders v Winship, 57 NY2d 391; McKinney’s Cons Laws of NY, Book 1, Statutes § 98).
Special Term held that Kenvic was entitled to merge plaintiff’s previously separate lot into a single zoning lot without the latter’s knowledge or consent by virtue of subsection (b) of section 12-10 and former subsection (c), which has not been part of the Zoning Resolution since 1977. Subsection (b) was found to apply because the tract allegedly was, at all times, in “single ownership”. In this connection, the court found that the phrase “single ownership” has exactly the same meaning as the phrase “single fee ownership” used in current subsection (c) and that both require only that the tract be held by individuals or entities having an undivided interest in the entire tract. Former subsection (c) was also held to be available to Kenvic, notwithstanding that it had already been repealed by the time Kenvic purportedly effected its zoning lot merger, because of a grandfather provision added to section 12-10 in 1977. The court, as does the majority herein, read the grandfather provision as carrying forward in perpetuity “all pre-existing rights” under section 12-10 as it stood before its amendment.
To reach these conclusions, the legislative history of the 1977 amendment was ignored and a statutory construction tolerated which makes subsections (b) and (c) redundant; distinguishes subsections (c) and (d) on a basis which is not only illogical but flatly inconsistent with the language of the resolution; and reads back into law a subsection which was expressly repealed.
*496Subsection (b) defines as a zoning lot: “A tract of land, either unsubdivided or consisting of two or more contiguous lots of record, located within a single block, which, on the effective date of this resolution or any applicable subsequent amendment thereto, was in single ownership.” (Emphasis added.) Thus, the tract cannot qualify as a zoning lot under subsection (b) because the tract was not “in single ownership,” either at the time of the purported zoning lot merger or on August 18,1977, the effective date of the 1977 amendment of the “zoning lot” definition.
To have “single ownership” within the meaning of subsection (b), there must be single ownership of all interests in the property. The tract here was thus not “in single ownership” because of the existence of multiple interests in the property, including plaintiff’s ground lease.
Unlike the other subsections of section 12-10 dealing with tracts containing multiple lots, subsection (b) contains no procedures, such as a certification of parties in interest or a declaration of zoning lot merger, for taking into account the interests of other parties who have an interest in all or part of the tract. Such procedural safeguards are necessary unless all interests in the property are in the hands of one party, as is required under subsection (b). If the drafters of the 1977 amendment of section 12-10 had contemplated the application of subsection (b) when multiple interests in a tract exist, they would have written in procedural safeguards at the time of the amendment to ensure that the goals of notice and consent would be met before a zoning lot merger could be effected. Since no such safeguards were considered necessary, subsection (b) must be read as applying only where all interests in the tract are in single ownership.
The plain language of section 12-10 further supports this construction of subsection (b). The requirement in subsection (b) that the tract must be “in single ownership” stands in sharp contrast to the reference in subsection (c) to “under single fee ownership” (emphasis added). Subsection (c) may, if other required conditions are met, be available in circumstances where there is single ownership only of the fee, notwithstanding the presence of other interests in the property. Subsection (b), on the other hand, requires that the tract be “in single ownership,” without any reference to the fee, and must be read as being applicable only where all interests in the lots involved are held singly. If the two phrases — “in single ownership” and “under single fee ownership” — are, despite their notable difference, treated as interchangeable, as Special Term’s interpretation requires, then subsection (c) loses all independent meaning and *497becomes redundant since any tract qualifying under subsection (c) would also necessarily qualify under subsection (b). The court’s reading of section 12-10 thus renders subsection (c) meaningless.
Under the only logical interpretation of subsection (b), it plainly was not available to Kenvic as a means of creating a single zoning lot. As a ground lessee with the right to exploit the development rights attributable to its lot for the duration of the lease, plaintiff now has, and has had at all times since 1959 when the lease was made, a significant interest in the property. Thus, the tract was not “in single ownership” under subsection (b) at any conceivably relevant time, and subsection (b) was unavailable to Kenvic.
To qualify as a zoning lot under subsection (c), a tract must be “under single fee ownership” and each party having any interest in the tract must be a “party in interest” as that term is defined for purposes of subsection (c). For purposes of subsection (c),. a “party in interest” includes only the following: “(W) the fee owner thereof, (X) the holder of any enforceable recorded interest superior to that of the fee owner and which could result in such holder obtaining possession of all or substantially all of such tract of land, (Y) the holder of any enforceable recorded interest in all or substantially all of such tract of land which would be adversely affected by the development thereof and (Z) the holder of any unrecorded interest in all or substantially all of such tract of land which would be superior to and adversely affected by the development thereof and which would be disclosed by a physical inspection of the tract of land.” (Emphasis added.)
In light of the language and the purpose of section 12-10, subsection (c) must, therefore, be read as applying only when there is single fee ownership of the tract and each party having any interest in the property is a “party in interest” as that term is defined for purposes of subsection (c). That requirement is not met here, as Special Term apparently agreed since it found that subsection (c) did not apply. Although Kenvic may have had single fee ownership of the tract, every party having an interest in the tract was not a “party in interest” as defined for purposes of subsection (c). As the holder of an unexpired ground lease in a lot incorporated in the tract involved here, plaintiff unquestionably has an interest in the tract, and Kenvic conceded below that plaintiff was not a “party in interest” as that term is defined in subsection (c).
*498Subsection (d), which the court below also found unavailable to authorize Kenvic’s actions here (presumably because of Kenvic’s failure to obtain plaintiff’s consent to the zoning lot merger), defines as a zoning lot: “A tract of land, either unsubdivided or consisting of two or more lots of record contiguous for a minimum of ten linear feet, located within a single block, which at the time of filing for a building permit (or, if no building permit is required, at the time of filing for a certificate of occupancy) is declared to be a tract of land to be treated as one zoning lot for the purpose of this resolution * * * Each Declaration shall be executed by each party in interest (as defined herein) in the portion of such tract of land covered by such Declaration (excepting any such party as shall have waived its right to execute such Declaration in a written instrument executed by such party in recordable form and recorded at or prior to the recording of the Declaration.” Subsection (d) was intended to come into play in situations, such as the present one, in which none of the previous subsections of section 12-10 apply because there are entities holding less than fee interests in the property and such interests do not extend to all or substantially all of the tract. In such circumstances, in order for the full tract to qualify as a single zoning lot, a declaration of zoning lot merger must be executed by all “parties in interest” as that term is defined for purposes of subsection (d). As used in subsection (d), the term “party in interest” is far more broadly defined than in subsection (c) to include: “(W) the fee owner or owners thereof, (X) the holder of any enforceable recorded interest in all or part thereof which would be superior to the Declaration and which could result in such holder obtaining possession of any portion of such tract of land, (Y) the holder of any enforceable recorded interest in all or part thereof which would be adversely affected by the Declaration, and (Z) the holder of any unrecorded interest in all or part thereof which would be superior to and adversely affected by the Declaration and which would be disclosed by a physical inspection of the portion of the tract of land covered by the Declaration.” (Emphasis added.) Plaintiff clearly is a “party in interest” under both parts (X) and (Y) of the quoted definition since it is a ground lessee of a portion of the tract under a recorded, enforceable lease which is superior to the declaration; it already has possession of a portion of the tract; and it is adversely affected by the treatment of the tract as one zoning lot inasmuch as such treatment caused the permanent loss of its development rights and substantially limited its rights to remodel and renovate during the balance of its lease. As a “party in interest”, plaintiff’s participation in a declaration under subsec*499tion (d) was required. Since plaintiff did not execute the requisite declaration with respect to the tract, the tract cannot qualify as a single zoning lot under subsection (d).
In addition to finding that Kenvic’s tract was a single zoning lot under subsection (b), Special Term held that by virtue of a grandfather provision added to section 12-10 in 1977 (referred to by Special Term as subdivision [e]), the tract also qualifies as a zoning lot under the former subsection (c) which was repealed in 1977.
The grandfather provision, which was added to section 12-10 in 1977 when the amendment of section 12-10 eliminated the prior definition of “ownership” which had included long-term leases, states: “Where ownership of a zoning lot or portion thereof was effected prior to the effective date of this amendment, as evidenced by an attorney’s affidavit, any development, enlargement or alteration on such zoning lot may be based upon such prior effected ownership as then defined in the zoning lot definition of Section 12-10. Such prior leasehold agreements shall be duly recorded prior to August 1,1978.” The sole purpose of the grandfather clause was to make clear that a 75-year lease which constituted “ownership” as previously defined in section 12-10 would continue to be recognized as “ownership” thereafter if the lease arrangement was already in effect and the lease was recorded within one year after the amendment. The grandfather clause was intended to grandfather a definition of “ownership,” not to grandfather the right to effect a zoning lot merger in a manner which had already proved sufficiently unsatisfactory to require its appeal.
Regarding the grandfather provision, Norman Marcus, counsel to the City Planning Commission, wrote: “The new zoning-lot definition grandfathers assemblages completed prior to its effective daté that are subsequently recorded within a year following 'its effective date. The city did not intend to force renegotiation of assemblages, including long-term development rights leases, which satisfied the old zoning-lot definition. The statute’s objective of placing such assemblage long-term lease relationships on record, is achieved by requiring, as a condition of grandfather status, the recordation of such leases prior to August 1, 1978.” (Marcus, From the Legislatures, 6 Real Estate LJ 336, 339 [1978].) The City Planning Commission memorandum clearly reflects the same purposé: “In order to protect the interests of all parties holding interest in a lot merger effected through leasehold arrangements prior to the effective date of this amendment, provision for recordation of their agreement *500has been incorporated into the proposed text amendment.” (City Planning Commn Amend of Zoning Resolution, July 13, 1977, Cal No. 27, at 3.)
The grandfather provision was not intended to have any application whatsoever to a situation such as this one where there is no claim to ownership by virtue of a long-term lease. This fact is made clear by the final sentence of the grandfather provision which reads, “Such prior leasehold agreements shall be duly recorded prior to August 1, 1978” (emphasis added). The sentence confirms that the grandfather provision was intended to deal exclusively with long-term leasehold situations. Thus, the grandfather provision has no relevance here and cannot reasonably be read to have given Kenvic the right to proceed under a subsection of section 12-10 which is no longer part of the Zoning Resolution.
