*752This appeal is brought by the defendant, the East Lyme Zoning Board of Appeals (board), from a decision of the trial court sustaining an appeal from the board's decision denying a building permit for a parcel of land owned by the plaintiff, Fortunata Maluccio, that was designated as a "recreation area" on an original subdivision plan. The defendant claims that the trial court improperly found that the designation of the parcel as a "recreation area" did not preclude the development of that parcel for residential use. We affirm the judgment of the trial court.
The following facts and procedural history are relevant to this appeal. The plaintiff purchased a lot with the address of 6 Red Fox Road (parcel) in the Green Valley Lakes subdivision in East Lyme (town) at a tax sale on May 26, 2006. The Green Valley Lakes subdivision was originally approved on July 13, 1970, by the East Lyme Planning Commission (commission). The East Lyme Subdivision Regulations (regulations), as they existed in 1970, gave the commission discretion to require developers to provide land to the town for "open space for parks and playgrounds as it may deem proper ...." East Lyme Subdivision Regs. (Rev. to June 5, 1967), § 3.5. Accordingly, the developer of Green Valley Lakes designated one lot as a "recreation area" on the subdivision plan he submitted for approval to *753the commission. The lot labeled "recreation area" is the parcel at issue in this appeal.
At its meeting on July 13, 1970, the commission approved the subdivision plan that included the parcel labeled as a "recreation area." The vote on the subdivision, however, did not explicitly mention whether a recreation area would be required. On February 14, 1972, the developer recorded on the land records of the town a "Declaration of Restrictions" relating to the subdivision. No mention was made of the parcel, any special restrictions regarding the parcel, or any rights created for the use of the parcel by any lot owners.
On July 5, 1973, the original developer offered to deed the parcel to the town. The minutes of the town Board of Selectmen meeting state that, following a discussion, the selectmen voted unanimously to reject the offer. Once more, in 1979, a subsequent developer also offered to deed the parcel to the town, but the offer was rejected. The parcel has remained in its natural state since 1970, has not been classified as open space by the assessor, and does not appear as open space on the town's plan of development or comprehensive plan. No rights in the parcel were deeded to lot purchasers in the development, and no lot owner has filed a notice of claim as to any rights in the parcel pursuant to General Statutes § 47-33f.1
Following years of unpaid taxes on the parcel, it became the subject of a statutory tax sale by a public auction conducted by the town's tax collector. A public notice regarding the sale was issued on March 10, 2006. The notice indicated that the parcel was to be sold *754subject to a utility easement and sloping rights, but made no mention of any encumbrance relating to open space for parks and playgrounds. The plaintiff purchased the parcel at the tax sale for $19,500.
In August, 2012, the plaintiff submitted an application to the town for a zoning *72permit to build a single family home on the parcel. The application and attached plans conformed to all specific requirements of the zoning regulations of the town.2 The zoning enforcement officer, acting on behalf of the East Lyme Zoning Commission, denied the permit application, stating his reasons as follows: "[The] application is denied as property is designated as recreation area open space on the original subdivision plan."
The plaintiff appealed from the denial of her permit application to the defendant, which, following a hearing, upheld the zoning enforcement officer's decision. The defendant stated that the zoning enforcement officer "had properly denied the zoning permit for [the parcel], [and] that designations of the original subdivision map such as recreation area, open space, etc., were purely semantics as they all serve the same function and the opinion of the attorney was that they were synonymous as you are talking about language from 1970 and now. Further, it was recommended that the appropriate method of change for this item is through the [commission]."
Pursuant to General Statutes § 8-8(b), the plaintiff appealed from the decision of the defendant to the Superior Court. The court sustained the plaintiff's *755appeal, holding that the decision of the defendant was illegal and not supported by the record. Specifically, the court reasoned that the notation of "recreation area" on the original subdivision plans submitted for approval in 1970 created only, if anything, a private right or restriction that cannot be enforced by the zoning enforcement officer or the defendant. Further, the court observed that the town had twice rejected offers from developers to deed the parcel to the town for recreational purposes, and therefore the parcel was never deeded or dedicated to the town as a "recreation area." The court remanded the case to the defendant with direction to reverse the ruling of the zoning enforcement officer. On the granting of certification, this appeal followed. Additional facts will be set forth as necessary.
We begin by setting forth the applicable standard of review. "In reviewing the actions of a zoning board of appeals, we note that the board is endowed with liberal discretion and that its actions are subject to review by the courts only to determine whether [they were] unreasonable, arbitrary or illegal.... The burden of proof to demonstrate that the board acted improperly is upon the party seeking to overturn the board's decision....
"It is well settled that ... [t]he court's function is to determine on the basis of the record whether substantial evidence has been presented to the board to support its findings.... Upon an appeal from the judgment of the trial court, we review the record to see if there is factual support for the board's decision, not for the contentions of the applicant ... to determine whether the judgment was clearly erroneous or contrary to law."

*756"When a zoning agency has stated its reasons for its actions, a court *73should not reach beyond those stated purposes to search the record for other reasons supporting the commission's decision.... Rather, the court should determine only whether the assigned grounds are reasonably supported by the record and whether they are pertinent to the considerations which the authority was required to apply under the zoning regulations." (Citations omitted; internal quotation marks omitted.) Harris v. Zoning Commission , 259 Conn. 402, 420-21, 788 A.2d 1239 (2002).
A zoning enforcement officer acting on an application for a zoning permit has a purely ministerial function. See Roraback v. Planning & Zoning Commission , 32 Conn.App. 409, 412, 628 A.2d 1350, cert. denied, 227 Conn. 927, 632 A.2d 704 (1993) ; but see Reardon v. Zoning Board of Appeals , 311 Conn. 356, 364-65, 87 A.3d 1070 (2014) (enforcement of zoning regulations generally discretionary). If the application conforms to the requirements of the regulations, he has no discretion but to issue a permit. See Langer v. Planning & Zoning Commission , 163 Conn. 453, 456, 313 A.2d 44 (1972).
In the present case, we agree with the trial court's conclusion that the action taken by the defendant in upholding the denial of the plaintiff's permit was illegal and unsupported by the record. The defendant can exercise only such powers as are expressly granted to it by statute. Moscowitz v. Planning & Zoning Commission , 16 Conn.App. 303, 308, 547 A.2d 569 (1988). General Statutes § 8-6(a) provides in pertinent part: "The zoning board of appeals shall have the following powers and duties: (1) [t]o hear and decide appeals where it is alleged that there is an error in any order, requirement or decision made by the official charged with the enforcement of this chapter or any bylaw, ordinance or regulation adopted under the provisions of this chapter ...." General Statutes § 8-7 provides in relevant *757part: "The board shall hold a public hearing on such appeal .... Such board may reverse or affirm wholly or partly or may modify any order, requirement or decision appealed from and shall make such order, requirement or decision as in its opinion should be made in the premises and shall have all the powers of the officer from whom the appeal has been taken but only in accordance with the provisions of this section. Whenever a zoning board of appeals ... sustains or reverses wholly or partly any order, requirement or decision appealed from, it shall state upon its records the reason for its decision ...."
In upholding the decision made by the zoning enforcement officer, the defendant formally stated the reasons for its decision on the record. The reason provided was that the label "recreation area" on the subdivision map precluded the plaintiff from obtaining the building permit. As the trial court aptly noted, however, "[t]he law is well established that restrictive covenants in a deed as to use of property are distinct and separate from the provisions of a zoning law and have no influence or part in the administration of a zoning law .... Anniello v. Vernon Planning & Zoning Commission , Superior Court, judicial district of Tolland, Docket No. CV-93-52916-S [1995 WL 493781, *3] (August 14, 1995)." (Internal quotation marks omitted.); see also Am. Jur. 840, Zoning and Planning, § 1006 (1992). On appeal, the defendant contends that the court erred in determining that the label "recreation area" on the subdivision map created, if anything, a private right or restriction unenforceable by the zoning enforcement officer or the defendant. Instead, the defendant asserts that, because such label was required by the regulations in effect in 1970, the parcel is currently designated as *74a recreation area, and the zoning enforcement officer therefore has the power to deny a permit to build on the parcel. *758The defendant's proposition fails in at least two regards. First, the regulations did not require an open space parcel, rather, the regulations merely required the developer to allocate a parcel as open space on the subdivision plan submitted for the application. The commission could then decide whether the open space parcel should be required. See East Lyme Subdivision Regs. (Rev. to June 5, 1967), § 3.5. In this case, the commission was silent on the matter, so it cannot be assumed that the commission eventually required the parcel to remain open space. Further, the developers twice offered to deed the parcel to the town but the town denied both offers. Had the town truly wished to ensure that the parcel would remain "open space" indefinitely under the regulations, it could have accepted title to the property. Second, the defendant's argument fails because, even if the regulations actually required the commission to designate the parcel as open space before approving the subdivision application, the designation of "recreation area" did not fall within the explicit confines of the regulations. Instead, the regulations allowed the commission the discretion to mandate that a developer provide land to the town for "open space for parks and playgrounds as it may deem proper ...." (Emphasis added.) East Lyme Subdivision Regs. (Rev. to June 5, 1967), § 3.5. The regulations made no mention of the commission's power to require the developer to set aside land for a "recreation area." Thus, because the commission lacked the authority to require the developer to designate a "recreation area," it follows that the zoning enforcement officer and the defendant could not deny the plaintiff a building permit for the parcel on the basis of its original "recreation area" designation on the subdivision plan.
The defendant's second claim on appeal, namely, that the court erred in determining that the town was *759required to accept title to the property in order to effectuate the recreation area designation, also fails. The defendant's argument is based on a misguided reading of the court's decision. Although the court stated that the parcel was not deeded and perpetually dedicated to the town for recreation, the court was responding to the defendant's argument that § 1.61 of the November 22, 2013 revision of the East Lyme Zoning Regulations applied to the parcel.3 Nowhere in its memorandum of decision did the court state that the town was required to accept title to the parcel to effectuate the recreation area designation. On the contrary, the court's review of the defendant's decision was not based on what action the town could have taken to effectuate the recreation area designation, but rather on the illegality of the action taken by the zoning enforcement officer and the defendant in denying the plaintiff a building permit. Accordingly, the court did not err, and the defendant's second claim fails.
We conclude that the court properly sustained the plaintiff's appeal and remanded the case to the defendant with direction to *75reverse the ruling of the zoning enforcement officer.
The judgment is affirmed.
In this opinion the other judges concurred.
