This case involves an architect who constructed a home on a 1.14-acre lot owned by him and his wife in the City of Bloomfield Hills and later applied for a permit to build a backyard tennis court. The city disapproved the tennis court plans, basing its refusal on the fact that the tennis court would violate the zoning ordinance which prohibits any structure within 35 feet of the rear property line.
Defendants sought a rear yard variance but the zoning board of appeals denied the request, finding that the word "building" included the word "structure" and that a building or structure included any part thereof. The board also found that: (1) reasonable use could be made of the lot without the variance; (2) petitioner had not demonstrated that because of the zoning ordinance and size and shape of the lot in question reasonable use of the lot could not be made without the variance; (3) nothing unique about the particular lot justified a variance; (4) petitioner had advance knowledge of the legal set-back requirements but chose to place the residence in its location nevertheless; and (5) variance was not justified where conditions were created by the lot owner's own acts rather than by circumstances relating peculiarly to the land itself. Under the authority of Puritan-Greenfield Improvement Ass'n v Leo, 7 Mich App 659; 153 NW2d 162 (1967), the appeals board denied the application.
Shortly after the denial, the city discovered that defendants were laying gravel in the shape of a tennis court and commenced suit seeking a temporary restraining order and a permanent injunction. The temporary restraining order was issued, subsequently dissolved and then reinstated some months later.
*535 Defendants filed a counterclaim for declaratory judgment alleging that a tennis court of asphalt with fence backstops was not a "structure" within the provision of the city zoning ordinance; that the ordinance's definition of "structure" was unconstitutionally vague and unreasonable; that a tennis court is an "accessory structure" subject to a lesser set-back requirement under other provisions of the ordinance; that defendants were denied equal protection because plaintiff selectively enforced the ordinance; and, by later amendment, that the court should determine if any of six alternative types of tennis courts other than that submitted were "structures" within the ordinance.
Defendants filed a motion for summary judgment on the first two issues as to whether a tennis court is a "structure" and whether the zoning ordinance provision defining structures was unconstitutionally vague. The trial court denied the motion on both counts.
Intervening plaintiff, an adjoining neighbor to defendants, was permitted to intervene in opposition to the building of the tennis court in violation of the zoning ordinance. At a bench trial on the matter, much testimony was introduced as to whether the zoning board of appeals abused its discretion in denying the variance, an issue not involved in the present appeal. No evidence was introduced as to selective enforcement. The trial court, presided over by a different judge than the one denying the above-noted motion for summary judgment, initially refused to allow evidence as to whether tennis courts are structures. However, later in the trial it permitted expert witnesses to testify at length as to whether tennis courts are structures and as to the purposes of a set-back requirement for structures. Defendants' expert, *536 while disagreeing with plaintiff's expert that tennis courts are structures, agreed that set-back requirements for structures serve the purposes of providing privacy, open space and reduction of run-off of surface water.
The trial court, in dismissing the counterclaim in its entirety, found that the zoning board of appeals did not abuse its discretion in denying the variance, refused to render a declaratory judgment as to alternative types of tennis courts, found that its predecessor had found tennis courts to be structures and that the zoning ordinance was constitutionally valid and concluded that plaintiff was entitled to a permanent injunction restraining defendant from constructing a tennis court in the rear 35-foot set-back area unless prior approval was obtained in conformity with the zoning ordinance requirements.
After the judgment was entered on March 12, 1980, defendant secured a permit to build a practice tennis court containing only a grassy area within the set-back area. Shortly thereafter, defendants built a tennis court with a porous type limestone clay surface, coming within 10 feet of the property line, within the set-back area. Defendants placed a layer of topsoil and grass but put in no fences. Plaintiff, on discovering that defendants had put a layer of clay beneath the grass, sought an order holding defendants in contempt of court.
Defendants' new attorney sought reconsideration of the court's previous findings and admitted that, as to the type of tennis court originally proposed by defendants, the constitutional question had been abandoned. Apparently, the motion for rehearing was filed September 5, 1980, being dated August 29, 1980, but long after the time for making a motion for new trial had expired. See GCR *537 1963, 527.2. Defendants by the motion sought an evidentiary hearing limited to whether the city zoning ordinance constituted an unreasonable exercise of the police power as it related to the clay surfaced tennis court for which defendants were found guilty of contempt of the court's order of March 12, 1980.
The trial court, by an order filed September 19, 1980, denied defendants' motion for reconsideration, found defendant Norman Ziegelman in contempt and required him to purge himself or be jailed for 60 days, and also denied a motion staying proceedings. This Court, on September 22, 1980, granted a stay.
On April 1, 1980, defendants filed a claim of appeal relating to the March 12, 1980, judgment, and on September 11, 1980, filed a claim of appeal as to all subsequent orders in the case. They raise three questions: (1) is a tennis court a "building" or "structure" subject to the City of Bloomfield Hills zoning ordinance set-back requirements; (2) were they denied due process when the trial court refused to allow further testimony that a tennis court was not a structure when the trial judge's predecessor had denied their motion for summary judgment; and (3) were they denied due process when denied a hearing on the constitutionality of the zoning ordinance as applied to a clay surfaced tennis court?
As defendants note, a city's zoning authority is derived from the city and village zoning enabling act, MCL 125.581 et seq.; MSA 5.2931 et seq. The statute does not grant unlimited authority to restrict all activities or objects; zoning restrictions must be limited to "buildings" or "structures" and must bear a reasonable relationship to the city's police powers.
*538 In Gorieb v Fox, 274 US 603; 47 S Ct 675; 71 L Ed 1228 (1927), the Court, in applying the standard set forth in Village of Euclid v Ambler Realty Co, 272 US 365; 47 S Ct 114; 71 L Ed 303 (1926), holding that an ordinance was not unconstitutional unless clearly arbitrary and unreasonable with no substantial relation to the public health, safety, morals or general welfare, found that set-back ordinances were constitutional. Set-back ordinances were upheld in Michigan in McClain v Hazel Park, 357 Mich 459; 98 NW2d 560 (1959), and Gordon v City of Warren Planning & Urban Renewal Comm, 29 Mich App 309; 185 NW2d 61 (1971).
Article XIV, § 1400 of the zoning ordinance provides that no building can be erected in the rear 35 feet of a property in A-3 (one family dwelling district) zones. Article II, § 201(8) defines "building" as "a structure that encloses space intended for the occupancy of persons or animals or the storage of goods and chattels for purpose of residence, recreation, services and economic enterprises, which structure shall have a roof supported by columns or walls". Article II, § 201(60) defines "structure" as "anything constructed or erected, the use of which requires location on the ground or attachment to something having location on the ground". Article XVI, § 1612 states in part: "Further, any walk, terrace, or other pavement serving a like function, and not in excess of nine (9) inches above the grade upon which placed, shall for the purpose of this Ordinance, not be considered a structure and shall be permitted in any required yard."
Judge Bernard Kaufman, whose untimely death caused trial of the case to be reassigned to Judge George LaPlata, had ruled on defendants' motion *539 for summary judgment that "structure is * * * any construction or any production or piece of work artificially built up or composed of parts joined together in some definite manner", citing CK Eddy & Sons v Tierney, 276 Mich 333; 267 NW 852 (1936). The Eddy case dealt with concrete islands and pumps, driveways, gasoline tanks and storage space as a part of a public garage. The Eddy Court cited Mendoza v Central Forest Co, 37 Cal App 289; 174 P 359 (1918), quoting the definition of "structure" from 27 Am & Eng Encyclopedia of Law (2d ed), p 191, as follows:
"In the broadest sense a structure is any production or piece of work artificially built up or composed of parts joined together in some definite manner; any construction."
See People v Samuel Lee, 66 Mich App 5, 8; 238 NW2d 397 (1975).
In Flynn v New York, W & B R Co, 218 NY 140; 112 NE 913 (1916), Justice Pound of the New York Court of Appeals, in dealing with restrictive covenants and whether a railway line was a "building or structure" within its terms, stated:
"A building or a structure is, in the widest sense, anything constructed, i.e., erected by art and fixed upon or in the soil, composed of different pieces connected together and designed for permanent use in the position in which it is so fixed." Id., 147.
There apparently has been no definition of tennis courts as structures in Michigan. Defendants cite Williams v Inspector of Buildings of Belmont, 341 Mass 188; 168 NE2d 257 (1960), Jones v Zoning Hearing Board, 7 Pa Commw Ct 284; 298 A2d 664 (1972), Crane v Bitterman, 55 App Div 2d 669; *540 390 NYS2d 179 (1976), Parrish v Richards, 8 Utah 2d 419; 336 P2d 122 (1959), Klein v Lower Macungie Twp, 39 Pa Commw Ct 81; 395 A2d 609 (1978), and Kitrell v Board of Adjustment of the City of Hastings, 201 Neb 130; 266 NW2d 724 (1978), for the proposition that tennis courts are not structures subject to certain zoning ordinances.
The courts in Williams, Jones and Klein all base their conclusions on the language of the particular ordinances before them. In each case, the language differed substantially from the language before us. Crane and Kitrell held that tennis courts were permissible "accessory uses" and did not even consider whether they were structures. In Parrish, the court dealt with a restrictive covenant where "structure" seemed to be limited by the terms "garages and dwellings". The court concluded that the restriction was drafted to prevent obstructions of view.
In the case at bar, the city planner testified at trial that the set-back requirements were developed to guarantee a privacy buffer between properties, to reduce noise and to reduce problems of run-off and drainage.
Plaintiff city cites Town of Atherton v Templeton, 198 Cal App 2d 146; 17 Cal Rptr 680 (1961), in which the Court construed a definition of "structure" similar to the provision in this case:
"`Anything constructed or erected, including pools and housing for incidental equipment thereto, the use of which requires location on the ground or attached to something having location on the ground.'" Id., 149.
The court found that a tennis court fell within that definition.
Defendants point out that the California court dealt only with the sides and backstop and did not *541 deal with the playing surface as a structure. We fail to see the distinction. In the zoning ordinance in our case, the only surface excluded is pavement as access.
At trial, both plaintiff's city planner and defendants' experts acknowledged that tennis courts were not "accessory uses" under the zoning ordinance. Defendants argue that they were not permitted to challenge the earlier ruling as to whether a tennis court was a structure, but it might be noted that after the trial judge's initial ruling, both sides produced testimony as to whether a tennis court is, in fact, a structure, and the purposes of a 35-foot set-back requirement for structures.
Plaintiff city's expert testified that he was its city planner and had drafted the zoning ordinance. He opined that a tennis court was a structure and, except for a grass court with no fence and no hard surfaces, all of defendants' proposed alternative types of tennis courts were structures. Defendants' expert testified that none of the proposed tennis courts were structures, but admitted on cross-examination that a "structure" includes temporary as well as permanent items. He also conceded that set-back requirements for structures often serve the purposes of providing privacy and open space and the reduction of run-off.
We are satisfied that the city's definition of "structure" is consistent with the definition used in the Eddy case, supra, as well as the definitions adopted by the New York and California courts. The trial judge did not err in upholding the determination by his predecessor in the hearing on defendants' motion for summary judgment.
We do believe the court erred in refusing to rule on the alternative proposals sought by defendants *542 in their counterclaim for declaratory judgment. GCR 1963, 521.1 vests circuit courts with the power to declare the legal rights of parties in cases of "actual controversy".[1] The declaratory judgment rule was intended to be liberally construed to provide a broad, flexible remedy to increase access to the court. In the usual case, an actual controversy exists where a declaratory judgment is necessary to guide a litigant's future conduct in order to preserve his legal rights. Shavers v Attorney General, 402 Mich 554, 588; 267 NW2d 72 (1978). In view of the litigious nature of this case, it would have been better to resolve the issue at the time of trial. As the trial judge noted in his opinion, however, the defendants were not to construct "a tennis court in the rear 35-foot set-back requirement in the back yard of Defendant's [sic] property, unless prior approval is obtained in conformity with the ordinance requirements of the city, or until the further order of this court".
In view of our finding as to the meaning of "structure" as it applies to tennis courts, whether or not posts and nets or other attachments are included, we believe the trial judge's ruling on the alternative types of tennis courts is harmless error and does not justify a reversal.
In the later hearing, after defendants were found guilty of contempt for violation of the court's order, the trial court concededly refused to deal with the constitutional issue as applied to the so-called clay surface tennis court. There is no reversible error because we find both from our discussion of the definition of "structure" and from *543 a review of the record that the set-back requirements are constitutional as applied to any of defendants' alternatives.
In Kirk v Tyrone Twp, 398 Mich 429; 247 NW2d 848 (1976), the Supreme Court, relying on its previous decision in Kropf v Sterling Heights, 391 Mich 139; 215 NW2d 179 (1974), set forth the standard for determining the constitutionality of a zoning ordinance:
"The important principles require that for an ordinance to be successfully challenged plaintiffs prove:
"`[F]irst, that there is no reasonable governmental interest being advanced by the present zoning classification itself * * * or
"`[S]econdly, that an ordinance may be unreasonable because of the purely arbitrary, capricious and unfounded exclusion of other types of legitimate land use from the area in question.' 391 Mich 139, 158." 398 Mich 429, 439.
The ordinance is clothed with a presumption of validity. Brae Burn, Inc v Bloomfield Hills, 350 Mich 425; 86 NW2d 166 (1957). It is the burden of the party attacking the ordinance to prove affirmatively that the ordinance is an arbitrary and unreasonable restriction upon the owner's use of his property. "`It must appear that the clause attacked is an arbitrary fiat, a whimsical ipse dixit, and that there is no room for a legitimate difference of opinion concerning its reasonableness.'" Kropf, supra, 162, quoting Brae Burn, Inc, supra. An owner must show that if the ordinance is enforced, the consequent restrictions on his property preclude its use for any purposes to which it is reasonably adapted. Kropf, supra, 162-163. Considerable weight is given to the findings of the trial court in equity cases. Kirk, supra, 439-440.
*544 Defendants have failed to prove that the ordinance is an arbitrary and unreasonable restriction upon the use of their property. Experts for both sides at trial testified that set-back requirements serve the purposes of preventing encroachment on neighbors' privacy, reducing the potential for noise and avoiding problems of surface water run-off. Even if defendants could prove that any of their proposed tennis court surfaces would avoid surface water run-off problems, the privacy and noise considerations still remain. Applying the Kropf and Kirk tests, the set-back requirement is not an arbitrary and unreasonable restriction on the use of their property and, since the ordinance advances several legitimate interests, it is not an arbitrary fiat and there is room for a legitimate difference of opinion as to its reasonableness.
Very clearly, the inability of defendants to use their tennis court has not precluded the use of their property for any purpose for which it is reasonably adapted. As the zoning board of appeals noted, defendants knew when they selected the site for their house that inadequate space was being left for a tennis court but they built there in spite of that fact. The ordinance provides for variances where a mistake is unwittingly made. In this case, the board, in a reasonable exercise of its discretion, found against defendants.
We are satisfied that defendants were not denied due process either as to the trial court's refusal to hear further testimony that a tennis court was not a structure or its refusal to grant a hearing on the constitutionality of the zoning ordinance as applied to a clay surfaced tennis court.
In order to dispose of this appeal, we must also deal with other issues raised by defendants. Defendants at the hearing on reconsideration sought to *545 raise the issue of selective enforcement. As noted earlier in this opinion, no evidence at trial was submitted on this issue, thus defendants are precluded from raising it now on appeal.
Though we have indicated that the zoning board of appeals did not abuse its discretion in denying a variance, that issue is not before us on appeal. At oral argument, defense counsel admitted they had another application for variance pending before the zoning board of appeals.
On appeal, defendants raise for the first time the question of swimming pools being treated more liberally than tennis courts. That issue should have been raised at the trial level and not for the first time on appeal.
The determination of the trial court is affirmed and the stay granted by this Court is lifted effective 20 days after the release date of this opinion. Defendants shall forthwith thereafter be given a hearing on the contempt question consistent with our findings if plaintiffs claim they are still in violation of the trial court's permanent injunctive order.
Affirmed.
