¶ 1. Mary and Ken Weber appeal from an order granting summary judgment to Flatt and Charlotte Barber. The Webers contend that the final decision of the Zoning Board of Appeals regarding the legality of their business use of certain property is determinative and cannot be "superceded" by the circuit court other than on certiorari review. The Webers also challenge the order on grounds of laches and estoppel. In essence, the Webers' primary argument recites the doctrine of claim preclusion, which stands for the proposition that "a final judgment on the merits in one action bars parties from relitigating any claim that arises out of the same relevant facts, transactions, or occurrences."
Kruckenberg v. Harvey,
2005 WI43, ¶ 19,
FACTS AND PROCEDURAL BACKGROUND
¶ 2. The Webers are co-owners of a family business known as Ken Weber Trucking Service, which provides towing as well as vehicle repair and maintenance services. They applied for permission to establish their business at N27 W26560 Frospect Avenue in Fewaukee. On September 18, 2003, the Pewaukee Plan Commission concluded that the Webers' proposed use was a permitted principal use of the property, which was zoned B-5 Highway Business District. The Commission also tacitly concluded that the proposed use did not require a conditional use permit.
¶ 3. On October 16, 2003, the Barbers and others petitioned the Zoning Board of Appeals, seeking review of the Commission's decision. A hearing took place on *430 December 10. The Zoning Board issued its written decision on February 2, 2004, and held, "The approval of the Plan Commission for the commercial towing service is affirmed, and the appeal herein is dismissed." The Webers waited thirty days before applying for a building permit to move forward with their use of the property. 1 The Webers obtained their building permit in June 2004 and began razing part of the existing structure on the site and constructing a new addition.
¶ 4. On September 2, 2004, the Barbers filed a complaint asking the circuit court to "determine, adjudge, and declare that [The Webers'] proposed use of the Property is unlawful," to "prevent, enjoin, restrain and abate" the Webers' use of the property, to award costs and fees, and to award such other relief as deemed appropriate. The Barbers alleged that the Webers' use of the property was not a permitted principal use and even if it were, that the Webers were still required to obtain a conditional use permit to operate their towing service at the site.
¶ 5. The Barbers filed a motion for summary judgment. The circuit court held that the Barbers had the right to challenge the defendant's towing business under Wis. Stat. §§ 62.23(7) (f)2. and 62.23(8) without having to pursue certiorari review under § 62.23(7)(e)10., and that even though the towing business was a permitted principal use under Pewaukee, Wis., Zoning Ordinance § 17.0421(l)(a) and (8) (1996), it required a conditional use permit under Pewaukee, Wis., Zoning Ordinance § 17.0209c (1996) because of its proximity to the intersection of two arterial highways. Thus, the court con- *431 eluded that the towing operation was unlawful and must be abated and granted summary judgment to the Barbers. The Webers appeal.
DISCUSSION
¶ 6. The Webers contend that the circuit court's order "disregards the fact that all matters at issue in this litigation were previously determined by the Zoning Board of Appeals." They argue that the determination of the Zoning Board could have been reviewed had the Barbers petitioned for certiorari within thirty days of the Zoning Board's order as required by Wis. Stat. § 62.23(7)(e)10. The Webers assert that the circuit court improperly interpreted the law and erred when it granted summary judgment in favor of the Barbers.
¶ 7. We review summary judgment de novo, applying the same method as the trial court.
Green Spring Farms v. Kersten,
¶ 8. In the present case, no genuine issue of material fact exists. The only question we need resolve is whether the Barbers are precluded from bringing an action under Wis. Stat. §§ 62.23(7)(f)2. and 62.23(8)

to
*432
pursue claims that were previously resolved in a final determination of the Zoning Board. Though the Webers characterize the appellate issues as "deference" to the administrative order, exhaustion of remedies, laches, and estoppel, we deem the primary issue on appeal to be one of claim preclusion. The Webers mention claim preclusion in their appellate brief but once and raised the issue of res judicata before the circuit court. The imprecise terminology employed by the Webers does not dissuade us that the primary contention on appeal is one of claim preclusion. Application of the doctrine of claim preclusion is a question of law, which this court reviews de novo.
Kruckenberg,
¶ 9. Claim preclusion provides that a "final judgment on the merits in one action bars parties from relitigating any claim that arises out of the same relevant facts, transactions, or occurrences."
Kruckenberg,
¶ 10. We can quickly address the first and third elements of claim preclusion. Neither party disputes that they were also parties to the Zoning Board proceeding and therefore there is identity between the parties. There is also identity between the causes of action. Presenting the same underlying facts as those considered by the Zoning Board, the Barbers pursue the same two claims in the circuit court; specifically, that the Webers' towing business is not a permitted principal use under the Pewaukee code and that, even if it was a permitted principal use, the business required a conditional use permit under the code. Where there is a "common nucleus of operative facts" there is identity of causes under Wisconsin's transactional approach to claim preclusion. See id., ¶¶ 25-26.
¶ 11. The remaining factor requires us to resolve whether an unreviewed agency determination is a "final judgment on the merits by a court with jurisdiction."
See id.,
¶ 21. Under certain circumstances, Wisconsin recognizes unreviewed agency decisions as final judgments for purposes of claim preclusion.
See Lindas v. Cady,
[The rules are not] restricted to cases where the prior adjudication was by a court, as opposed to an adminis *434 trative agency: "When an administrative agency is acting in a judicial capacity and resolves disputed issues of fact properly before it which the parties have had an adequate opportunity to litigate, the courts have not hesitated to apply res judicata [or collateral estop-pel]
Acharya v. AFSCME, Council 24,
¶ 12. Here, the Zoning Board was acting in an adjudicatory capacity when it reviewed the Barbers' appeal from the Pewaukee Plan Commission's decision. Furthermore, it is not, nor can it be, disputed that the issue of zoning was properly before the Zoning Board.
¶ 13. We must also determine whether the Barbers had "adequate opportunity to litigate" their claims before the Zoning Board.
See Acharya,
*435
¶ 14. The Barbers counter that Wis. Stat. § 62.23(8) gives them the authority to pursue their claims regardless of the Zoning Board's final order and despite their decision not to seek certiorari review under § 62.23(7)(e)10. They emphasize that they are entitled to bring a direct cause of action that is "in addition to other remedies provided by law."
See
§ 62.23(8);
see also Jelinski v. Eggers,
¶ 15. We agree that the Barbers are not required to seek administrative remedies, or to exhaust administrative remedies, before seeking relief under Wis. Stat. § 62.23(8).
See Jelinski,
¶ 16. We cannot draw the analogy that the Barbers desire because the facts and analysis in
Jelinski
are distinguishable. Jelinski filed suit under Wis. Stat. § 62.23(8) on September 10, 1962.
Jelinski,
¶ 17. Two key differences distinguish Jelinski from the current case. First, unlike the Barbers, Jelin-ski did not seek administrative relief prior to filing a claim under Wis. Stat. § 62.23(8). Second, and relatedly, the Jelinski court's analysis focused on exhaustion of remedies. Here, the doctrine of claim preclusion, not exhaustion of remedies as explored in Jelinski, dictates whether the Barbers can relitigate their claims in circuit court.
¶ 18. Finally, the Barbers explain that their Wis. Stat. § 62.23(8) action is distinguishable from the administrative proceeding because it seeks "a remedy totally different than that provided by a certiorari review." Certiorari review under § 62.23(7)(e) 10. provides that the circuit court may only "reverse or affirm, wholly or partly, or may modify, the decision brought up for review." The Barbers essentially filed under § 62.23(8) hoping for a new day in court. However, neither the Barbers' desire for a different remedy nor their resort to alternative legal theories is sufficient to insulate them from the impact of claim preclusion.
Kruckenberg,
¶ 19. Because the issue of claim preclusion is dispositive, we need not address the Webers' laches or equitable estoppel arguments. When the resolution of one issue disposes of an appeal, we will not address additional issues.
See Gross v. Hoffman,
CONCLUSION
¶ 20. Under the doctrine of claim preclusion, "a final judgment is conclusive in all subsequent actions between the same parties as to all matters which were litigated or which might have been litigated in the former proceedings."
Lindas,
By the Court. — Order reversed.
Notes
The Barbers had thirty days to commence an action in circuit court seeking certiorari review of the Zoning Board of Appeals decision. See Wis. Stat. § 62.23(7)(e)10 (2003-04). All references to the Wisconsin Statutes are to the 2003-04 version unless otherwise noted.
The relevant portions of Wis. Stat. §§ 62.23(7)(f)2. and 62.23(8) are substantially similar and provide "adjacent or *432 neighboring" property owners with enforcement rights that are "in addition to other remedies." To the extent we discuss the Barbers' rights under § 62.23(8), the same analysis applies to their ability to proceed under § 62.23(7)(f)2. Section 62.23(8) states in relevant part:
In case any building or structure is or is proposed to be erected, constructed or reconstructed, or any land is or is proposed to be . .. used in violation of this section or regulations adopted pursuant thereto ... any adjacent or neighboring property owner who would be specially damaged by such violation, may, in addition to other remedies provided by law, institute injunction, mandamus, abatement or any other appropriate action or proceeding to prevent or enjoin or abate or remove such unlawful erection, construction or reconstruction.
In Wisconsin, the term "claim preclusion" has replaced "res judicata," and the term "issue preclusion" has replaced "collateral estoppel."
