(dissenting). The language of the zoning bylaw itself, as well as its legislative history and good sense, ■separately and in combination requires the conclusion that single-family homes subject to time-sharing or time-interval ownership in Nantucket are transient residential facilities, and therefore are not permitted in the zoning district in which the plaintiff’s lots lie.
It is unquestioned that the lots lie in a district from which the by-law excludes transient residential facilities. The question is whether the term “transient residential facilities” includes single-family homes subject to time-sharing, as well as multiunit buildings. Section 139-2 of the by-law defines transient residential facilities as “[hjotels, motels, lodging or guest houses and time-sharing or time-interval-ownership dwelling units.” The court concludes that a single-family home does not fit within that definition; more specifically, that a single-family home, whether or not subject to time-sharing, cannot contain a “dwelling unit.” The court concludes, as did the trial judge, that the term “dwelling unit” necessarily refers to a separate unit within a multi-family residence; a “subdivision” of a structure divided into “habitable subparts.” Ante at 139. But, *142nowhere in the by-law is the term “dwelling unit” defined or described as a separate unit in a multi-unit building, or as a subpart or a subdivision. Instead, “dwelling unit” is defined in § 139-2 as “[a] room or enclosed floor space within a dwelling used by, or forming a habitable unit for one (1) family with facilities for living, sleeping, cooking or eating.” The court does not explain why a room or enclosed floor space within a single-family home, used or appropriate for use as a residence for a single family, does not come within that definition. The court does not explain why such a room or space qualifies as a “dwelling unit” only if it is one of several such rooms or spaces in a single building. Read literally, the by-law treats dwelling units as habitable spaces in single or multiple-unit residences, and the by-law contains no inherent contradiction in language that requires manipulation by the court. A succession of occupants for brief periods is no less a transient use when it occurs in a single-family structure than when it occurs in a structure devoted to simultaneous multi-family use.
It cannot fairly be said that the Nantucket by-law unambiguously provides that single-family homes subject to time- sharing or time-interval ownership are permissible in zoning districts in which dwelling units in multi-unit buildings subject to time-sharing or time-interval ownership are prohibited. Thus, such a construction may be achieved, if at all, only by the use of interpretive aids traditionally invoked to resolve ambiguities. See Massachusetts Mut. Life Ins. Co. v. Commissioner of Corps. & Taxation, 363 Mass. 685, 690-691 & n.8 (1973); Murray v. Board of Appeals of Barnstable, 22 Mass. App. Ct. 473, 478 (1986). However, those aids point the other way. One such aid is judicial recognition that “[a] local board of appeals brings to the matter an intimate understanding of the immediate circumstances, of local conditions, and of the background and purposes of the entire by-law; and so, at least in the first instance, the board’s administrative view is valuable and is wanted.” Fitzsimonds v. Board of Appeals of Chatham, 21 Mass. App. Ct. 53, 57 (1985). Here, the Nantucket board of appeals concluded that single-family homes subject to time-sharing or time-interval ownership are not permitted in the zon*143ing district in which the plaintiff’s lots lie. In its decision, the board of appeals stated the following: “Counsel for [the plaintiff] would have us read the Zoning By-Law as if Time-Sharing Transient Residential Facilities were permitted in every residential zone if limited to a ‘dwelling’ as distinguished from a multiple ‘dwelling unit’ use. Or, as put by counsel, [the plaintiff] proposes to construct a Time-Shared ‘dwelling’ (presumably as a single-family residence permitted in the R-2 zone) without constructing a ‘dwelling unit’ and thus without the result constituting a ‘Transient Residential Facility’ barred in R-2. Comparing the definitions of ‘dwelling’ and ‘dwelling unit,’ such a ‘dwelling’ would necessarily not include within it a ‘room or enclosed floor space’ . . . ‘forming a habitable unit for, one (1) family . . .’ Clearly, [the plaintiff] strains in asking consideration of such a misreading. ‘Dwelling unit’ serves in counting units in a single or multi-unit ‘dwelling.’ ‘Transient Residential Facilities’ can, by definition, include time-shared dwellings with one or more dwelling units.” It would be difficult to find a board’s administrative view more at variance with the view adopted by the court than in the instant case.
Another aid to construction, related to that just discussed, is the legislative history of the by-law. Owens v. Board of Appeals of Belmont, 11 Mass. App. Ct. 994, 995 (1981). Like the view of the board of appeals, the relevant legislative history does not support the court’s result, but, instead, clearly cuts the other way. The provisions of the by-law regarding time-sharing were adopted at Nantucket’s annual town meeting held on April 7, 1982, pursuant to Article 14 on the town meeting warrant. Prior to adoption of that article, the Nantucket Planning and Economic Development Commission submitted a report to the town. A relevant paragraph taken from that report states as follows: “An important point to remember is that time-sharing does not have to be employed along with condominium ownership or be installed in multi-family structures, although clearly multi-family condos continue to be the principal ownership and structure types chosen for time-sharing thus far on the mainland. This distinction is particularly important *144in Nantucket’s case in view of the fact that Nantucket’s zoning does not now permit the new construction of multi-family residences and those that already exist are not particularly numerous. This means that under current zoning, most future time-sharing projects would probably involve conversion of existing or newly constructed single-family homes, with the exception of what few grandfathered multi-family apartment structure[s] exist.”
Not only does the legislative history contain the report just referred to, but also the town planning board submitted the following recommendation for the guidance of those voting at the town meeting: “The Planning Board RECOMMENDS FAVORABLE ACTION on Article 14 as written. The Board finds that time sharing or interval ownership constitutes a use of property which is clearly different in intensity, type, and degree from that normally associated with single family home use. The location of time sharing or interval ownership uses in heretofore stable, quiet residential neighborhoods is contrary to the general intent and purpose of the zoning by-law. The use of a structure for time sharing is very similar to the intensity, type and degree of use normally associated with such transient residential facilities as hotels, motels, and guest houses. For that reason, the Board feels that time sharing or interval ownership use should be permitted in districts which now allow transient residential facilities — Residential Commercial and Limited Commercial.” It is abundantly clear that the town intended by its by-law as amended to prohibit single-family homes subject to time-sharing or time-interval ownership in the district in which the plaintiff’s lots are located.
In view of its interpretation of the by-law, it was unnecessary for the court to reach the constitutional issues addressed by the trial judge and argued on appeal by the parties. In view of the by-law construction for which I argue, it is necessary that I focus on the constitutional questions at least briefly. The by-law as I would construe it does not violate art. 2, § 7 (5), of the Home Rule Amendment, as appearing in art. 89 of the Amendments to the Massachusetts Constitution as a regulation of civil relationships not incidental to a lawful exercise of zoning *145power. See CHR Gen., Inc. v. Newton, 387 Mass. 351, 353-358 (1982). A “fundamental principle of zoning [is that] it deals basically with the use, without regard to the ownership, of the property involved or who may be the operator of the use.” Id. at 356, quoting 1 A. Rathkopf, Zoning and Planning § 1.04, at 1-21 (4th ed. 1982). However, even if a zoning limitation is phrased in terms of types of ownership, it may be a valid regulation of use. See Goldman v. Dennis, 375 Mass. 197 (1978). In Goldman, the court concluded that “[t]he legislative body of the town could reasonably believe that conversion of a cottage colony to single family use under condominium type ownership would encourage expansion of use beyond the short summer season,” and that the town could restrict that expansion of use by restricting the type of ownership. Id. at 199. Clearly, Nantucket could reasonably have concluded that time-share ownership encourages use of property that is significantly different in intensity and nature from conventionally owned property.
The plaintiff’s due process challenge to the by-law is without merit. The test is “whether the challenged measure bears a rational relation to any permissible public object which the legislative body ‘may plausibly be said to have been pursuing.’” Sturges v. Chilmark, 380 Mass. 246, 256 (1980), quoting Blue Hills Cemetery, Inc. v. Board of Registration in Embalming & Funeral Directing, 379 Mass. 368, 372 (1979). As the town argues, control of the nature and intensity of use of residential areas, and the encouragement of use and ownership by persons with a significant stake in the community clearly are public objects which the town meeting “may plausibly be said to have been pursuing” in adopting the time-sharing provisions of the by-law. I would reverse the judgment below.
