BROWN, J.

Steamboat Realty, LLC, and its principal, James Rudolph (collectively, Steamboat) appeal from a decision of the Superior Court affirming the zoning board of appeal of Boston's (board's) denial of an application for a height variance for renovations made to the penthouse unit at 194 Beacon Street. We affirm.

A building permit was issued for the renovations based on plans that reflected no increase in the height of the roof line of the building. However, the judge, after a two-day bench trial, found that as built, the roof exceeds the preexisting height by at least four feet. Steamboat contends the actual increase is either zero or less than four feet four inches. When the Back Bay Architectural Commission made Steamboat aware of the height increase by issuing a notice of violation, Steamboat sought a variance for the "as built" plans. The board denied the variance. On appeal to the Superior Court, the judge affirmed the board's decision.

The standard of review we apply to a Superior Court decision reviewing a decision of a board of appeals on a variance is well settled. "We must accept the judge's findings of fact unless they are clearly erroneous, . . . but we are independently to 'determine[] what decision the law requires upon the facts found.'" 39 Joy St. Condominium Assn. v. Board of Appeal of Boston, 426 Mass. 485, 488 (1998) (citations omitted). In making this determination, we are cognizant that "[n]o person has a legal right to a variance and they are to be granted sparingly." Id. at 489, quoting from Broderick v. Board of Appeal of Boston, 361 Mass. 472, 479 (1972). "If variances (or exceptions, unless bestowed fairly in accordance with ascertainable standards properly stated in the zoning provisions) are granted with undue frequency or liberality, and without strict compliance with the prescribed statutory criteria, zoning regulations can become a matter of administrative whim." Damaskos v. Board of Appeal of Boston, 359 Mass. 55, 62(1971).

The criteria applicable to Steamboat's application for a variance, noted in the margin, are conjunctive; Steamboat must meet all of the criteria in order to qualify for a variance. See 39 Joy St. Condominium Assn. v. Board of Appeal of Boston, 426 Mass. at 489; McGee v. Board of Appeal of Boston, 62 Mass. App. Ct. 930, 931 (2004). Steamboat essentially concedes that it does not meet all of the criteria. It, for example, has identified no structural anomalies particular to the building that would distinguish it from neighboring buildings, particularly its adjacent mirror image, nor has it shown that a variance is necessary for the reasonable use of the land. Further, "an inability to maximize the theoretical potential of a parcel of land is not a hardship within the meaning of the zoning law." Id. at 932. Indeed, "[f]inancial hardship to the owner alone is not sufficient to establish 'substantial hardship' and thereby justify a variance." 39 Joy Street Condominium Assn. v. Board of Appeal of Boston, 426 Mass. at 490, quoting from McNeely v. Board of Appeal of Boston, 358 Mass. 94, 101 (1970). Where an applicant fails to meet the codified requirements for a variance, "it [is] not enough to show merely that the [applicant] ha[s] expended a substantial amount of money . . . or to show that there [are] other nonconforming buildings in the area, because neither fact constitute[s] a condition especially affecting the lot in question but not affecting that zoning district generally." Warren v. Zoning Bd. of Appeals of Amherst, 383 Mass. 1, 12 (1981). See Raia v. Board of Appeals of N. Reading, 4 Mass. App. Ct. 318, 321-322 (1976).

Steamboat's principal argument on appeal is that even assuming a height differential of four feet, four inches (see note 4, supra), and notwithstanding that it does not meet the criteria for a variance, a variance should have been granted on equitable principles that disfavor enforcing trivial or de minimis zoning infractions, particularly where the violation was made innocently, the cost to the applicant is great, and the harm to abutters is minimal. Steamboat argues that, pursuant to the teachings of Capodilupo v. Vozzella, 46 Mass. App. Ct. 224, 227 (1999), "a balancing of equities after due consideration of all pertinent facts" is necessary to determine whether this is one of the rare or exceptional cases where strict enforcement of the zoning code (here, by ordering restoration of the roof line) should be considered oppressive, inequitable, and illegal.

In support of its argument, Steamboat contends that it proceeded in good faith, innocently relying on the advice of a qualified architect, expended close to $300,000 to complete the renovations, and would have to spend another $300,000 to restore the roof line. Moreover, Steamboat points out that the building is one of the shorter buildings in the neighborhood notwithstanding the fact that, even before the renovation, it exceeded the current height limitation and therefore constituted a prior nonconforming use. Steamboat notes that the front roof line is unaltered; the alteration (visible from the back of the building) cannot be seen by a person standing at street level on Beacon Street. Steamboat argues further that at most, the height increase constitutes 6.6 percent of the total height of the building and should be deemed "de minimis." Finally, Steamboat notes the parties' stipulation that Steamboat's most immediate neighbor testified that he does not oppose the plan as built.

There is no order before us requiring Steamboat to return the roof to its previous condition. In the absence of such an order, an argument that principles of equity militate against literal enforcement of the zoning code strikes us as premature. However, in its decision the board concluded that Steamboat had failed to show that "this is a specific case where a literal enforcement of the [Zoning] Act involves a substantial hardship upon the Appellant as well as upon the premises, [or that] the described relief may be granted without substantial detriment to the public good and without substantially derogating from the intent and purpose of the Zoning Act." The parties have briefed the issue, and to the extent restoration of the original roof line is implicit in the variance decision, we exercise our discretion to reach the issue.

There is no merit to Steamboat's argument that the judge failed to balance the equities. In response to Steamboat's argument that equitable principles militate in favor of granting a variance, the judge found that the property at issue is located in the Back Bay section of Boston, where there is great concern in the neighborhood about attempts to build on top of existing structures. The judge noted that the board has consistently taken a tough stance on requests for variances that increase building height. Indeed, the evidence suggests that the board has refused to grant any height variances in the Back Bay neighborhood in the past ten or more years in order to "maintain the architectural integrity of the neighborhood as manifested in original, unbroken roof and cornice lines." This is true even where applicants came in with "clean hands" and claims of personal hardship. In addition, the Boston Redevelopment Authority voted to recommend that the board deny the variance petition because the "[e]xcessive height would not protect the character of the Back Bay Historic District" and the "Neighborhood Association of the Back Bay is opposed" to the petition.

The judge explained that she saw "nothing arbitrary or capricious with the Board's position. Indeed, it seems completely consistent with the purposes of the Zoning Code, which in part is designed to maintain the architectural integrity of existing buildings and encourage uses appropriate to the neighborhood." We agree.

We noted in Cottone v. Cedar Lake, LLC, 67 Mass. App. Ct. 464, 472 (2006), that judicial reluctance to enforce a demolition order has been based on factors such as the "lack of any violation of a private property interest, see Marblehead v. Deery, [ 356 Mass. 532, 537-538 (1969)]; the availability of money damages for the diminution, if any, in the fair market value of the abutting property, see Kelloway v. Board of Appeal of Melrose, [ 361 Mass. 249, 256-257 (1972)]; or the use of public funds in the construction of housing for the elderly. See Chambers v. Building Inspector of Peabody, [ 40 Mass. App. Ct. 762, 768-769 (1996)]." In none of the cited cases did the neighborhood, as here, have a well-established interest in preserving the architectural integrity of a historic neighborhood; nor did the zoning board in those cases have a record of furthering such an interest by consistently denying all requests for a height variance. Moreover, the judge here found that the height differential is not de minimis, and our review of the record does not reveal any error in that conclusion. We agree that the photographs, particularly those taken of the rear of the building, are quite telling as to the significance of the addition. We note also that Steamboat does not assert that the building, in its preexisting condition, was inadequate for reasonable uses such that failure to grant an exception could be considered unreasonable. Contrast Lombard v. Board of Appeal of Wellesley, 348 Mass. 788, 789 (1965) (denial of permit to enlarge garage to accommodate modern automobile, where building would encroach eighteen inches into twenty-foot side yard setback, was arbitrary and capricious).

The factors that led the court to provide equitable relief in Marblehead v. Deery, supra, cited extensively by Steamboat, differ significantly from the facts here. There, the town approved a plan for the subdivision of the defendant's property, including construction of a new road situated less than nine feet from the defendant's home. The defendant changed his position dramatically in reliance on approval of the plan: road construction and subsequent conveyances changed the defendant's access from the north to the east side of his property, resulting in his violation of the front yard setback requirement and causing him to be unable to relocate the road in such a way as to satisfy the setback requirement. 356 Mass. at 537. He also made significant improvements to the portion of the house that was in violation of the setback requirement. Ibid. The court concluded, based on the testimony of town officials, that no showing had been made of any public advantage that could result from a rigid enforcement of the by-law. Id. at 537-538.

Here, by contrast, the city did not approve a plan for the renovations that showed there would be an increase in the height of the roof line. In fact, the certificate of appropriateness issued by the Back Bay Architectural Commission was based on the fact that the application showed no increase in height or exterior volume. Nothing the city did contributed to any change of position by Steamboat. Moreover, in Marblehead v. Deery, supra at 536, the court found that the town's only objection was the technical violation of the zoning by-law. Here, in contrast, the public interest in maintaining the architectural integrity of the neighborhood is implicated.

Given that more is at issue here than the mere technical violation of a height restriction, that the city did not cause Steamboat to change its position, and that public monies are not involved, we discern no error in the judge's decision declining to grant a variance on equitable grounds. While the financial expenditures Steamboat has incurred and may incur in the future are regrettable, they do not supersede the board's interest in preserving the architectural integrity of the neighborhood.

We have not overlooked Steamboat's remaining arguments. "We find nothing in them that requires discussion." Department of Rev. v. Ryan R., 62 Mass. App. Ct. 380, 389 (2004), quoting from Commonwealth v. Domanski, 332 Mass. 66, 78 (1954).

Judgment affirmed.
