¶ 1 The primary issue in this case is whether a charter city, in the exercise of its general regulatory police powers, may ban light fixtures mounted on the bottom of existing billboards, or whether Arizona’s nonconforming use statute, A.R.S. § 9-462.02(A), precludes it from doing so. Adopting the latter view, the trial court granted partial summary judgment in favor of Whiteco Outdoor Advertising. The City of Tucson appeals from that ruling and the trial court’s judgment entered thereon. We vacate the judgment and remand for further proceedings.
BACKGROUND
¶ 2 Whiteco owns and maintains outdoor billboards used to display advertising copy. As of 1985, Whiteco had within the city a number of billboards illuminated by lighting fixtures mounted to the bottom of the billboard. In 1985, the City adopted an Outdoor Lighting Code (OLC) (Ordinance No. 6344), which required billboard lighting fixtures to be mounted on the top of the sign structure but exempted certain billboards of a specified size and design, within certain light spillage tolerances. The 1985 OLC expressly provided that any outdoor light fixtures “lawfully installed prior to and operable on the effective date of this code,” with certain inapplicable exceptions, were “exempt from all requirements of this code.”
¶ 3 In 1987, the City adopted another OLC (Ordinance No. 6786), which required all billboard lighting to be mounted on the top of the sign structure, and which removed the exemption for bottom-mounted billboard lighting. The 1987 OLC prohibited “bottom-mounted outdoor advertising sign lighting ... after December 31, 1987.” In 1994, the City again adopted an amended OLC (Ordinance No. 8210). Like the 1987 version, the
¶4 In August 1995, the City’s Development Services Director notified Whiteco that 170 of its billboards were in violation of the OLC’s prohibition of bottom-mounted billboard illumination and directed Whiteco to abate the violations. Whiteco appealed to the City Board of Appeals (the Board), contending that the City’s ability to regulate billboard lighting derived from the state’s zoning statutes and that the subject billboards are a protected nonconforming use under § 9-462.02(A), which provides in pertinent part:
Nothing in an ordinance or regulation authorized by this article shall affect existing property or the right to its continued use for the purpose used at the time the ordinance or regulation takes effect, nor to any reasonable repairs or alterations in buildings or property used for such existing purpose.
After a hearing, the Board denied Whiteco’s appeal, finding that ‘Whiteco’s utilization of bottom mounted illumination is not a nonconforming use, enforcement of the [OLC] against Whiteco is not discriminatory or in violation of Whiteco’s property rights____” Whiteco then filed this action in superior court, seeking special action relief ordering the city not to enforce the OLC prohibition against Whiteco, and a declaratory judgment that the OLC as applied only to billboard lighting is discriminatory and violates Whiteco’s due process rights.
¶ 5 The City moved for summary judgment, and Whiteco filed a cross-motion for partial summary judgment on the interpretation of § 9-462.02. The trial court denied the City’s motion and granted Whiteco’s, concluding that the 1985 and 1987 OLC’s “are zoning ordinances.” The trial court also concluded that Whiteco’s billboards illuminated by bottom-mounted lighting fixtures in existence before the 1987 OLC took effect are protected as nonconforming uses under § 9-462.02(A), and that the prohibition against such billboards “cannot be applied.” The court noted, however, that “such billboards are subject to and must comply with reasonable regulations under the governments’ [sic] police power to protect the health, safety, welfare or morals.”
¶ 6 The trial court denied the City’s post-ruling motions for clarification and to amend its answer by asserting a counterclaim. Over the City’s opposition, the trial court later entered judgment for Whiteco, declaring that its billboards illuminated with bottom-mounted lighting fixtures at the time the City adopted the 1987 OLC “are valid prior non-conforming uses protected under A.R.S. § 9-462.02,” and that the City exceeded its authority in requiring the removal of such bottom-mounted lighting fixtures. This appeal followed. 1
STANDARD OF REVIEW
¶ 7 Because of the procedural posture of this case, the applicable standard of review is somewhat convoluted. On appeal from a summary judgment, we must determine
de novo
whether there are any genuine issues of material fact and whether the trial court erred in applying the law.
Prince v. City of Apache Junction,
DISCUSSION
¶ 8 In granting partial summary judgment for "Whiteco, the trial court stated:
At the time of the adoption of the 1985 OLC and the 1987 OLC, the cited billboards were illuminated with bottom-mounted lighting fixtures. Consequently the cited billboards fall within the protection of A.R.S. § 9-462.02, as an existing non-conforming use at the time of the adoption of the ordinances. As the cited billboards were existing non-conforming uses at the time of the adoption of the ordinances, the Defendants acted in excess of its [sic] authority in requiring the removal of the bottom-mounted lighting fixtures. However, the City of Tucson may still pass reasonable regulations regarding these cited billboards to protect the public safety, health, welfare, or morals and may include limitations on light spillage.
That ruling, in turn, hinged on the trial court’s determination that the City’s OLC’s are “zoning ordinances.” We disagree with that characterization and with the ultimate ruling based thereon.
¶ 9 “[Z]oning authority comes from the state,” and “the power must be exercised within the limits and in the manner prescribed in the [state’s] grant [of zoning power to a city] and not otherwise.”
City of Scottsdale v. Scottsdale Associated Merchants, Inc.,
¶ 10 The issue, then, is whether the OLC, as applied to outdoor billboard advertising, is a sign regulation that is included within the City’s zoning power and therefore limited by state zoning laws, including the nonconforming use statute. We think not. Neither the state zoning laws nor the foregoing cases which Whiteco cites mention, let alone restrict, municipal authority to regulate lighting or illumination of signs.

Cf. Outdoor Systems,
The City of Tucson is a charter or “home rule” city organized pursuant to article 13, § 2 of the Arizona Constitution. As such, it may exercise all powers granted by its charter, provided that such exercise is not inconsistent with either the constitution or general laws of the state.
Jett v. City of Tucson,
¶ 11 In our view, the City’s charter provides a general police power to regulate billboard lighting that is not inconsistent with Arizona’s Constitution or general laws, and is not restricted by Arizona’s zoning statutes. That the City’s 1985 OLC exempted from its regulatory scope billboards with bottom-mounted lighting fixtures does not grant permanent “grandfathered” status to such fixtures or preclude subsequent OLC regulation affecting them.
See City of Fayetteville v. S & H, Inc.,
¶ 12 Even if the OLC’s were subject to Arizona zoning laws, that would not alter our conclusion. Relying on § 9-462.02(A), Whiteco contends, and the trial court agreed, that the City may not “retroactively” ban Whiteco’s bottom-mounted lighting fixtures. 3 We agree with the City, however, that that statute “only protects Whiteco’s non-conforming billboard structure as a land use for the display of advertising copy,” and “does not protect the means by which the billboard is illuminated.” The “existing property” protected by § 9-462.02, in our view, is Whiteco’s use of its illuminated outdoor advertising structures and the surrounding land on which they sit, see Outdoor Systems, not the mounting or location of lighting fixtures that provide the billboard illumination. To suggest that the City, in its exercise of general police powers, may not pass any regulations affecting the manner or mode of billboard lighting without violating the nonconforming use statute is an overbroad proposition that we decline to adopt.
¶ 13 In an analogous ease, Division One of this court rejected a similar proposition in
Watanabe v. City of Phoenix,
¶ 15 The trial court erred in characterizing the OLC’s as zoning ordinances and in ruling that § 9-462.02(A) precludes the City from applying its current OLC to Whiteco’s existing billboard light fixtures. Therefore, we vacate the judgment entered in favor of Whiteco on October 1, 1997, and deny its request for attorney’s fees. In view of this disposition, we do not address the City’s other issues. Because the trial court did not address WOiiteco’s constitutional claims, 4 we remand for consideration and resolution of those claims and for reconsideration, if appropriate, of the City’s motion for summary judgment.
Notes
. In its minute entiy granting partial summary judgment for Whiteco on the interpretation of § 9-462.02, the trial court noted that "the constitutional issues raised by the parties need not be addressed.” The judgment from which the City appeals does not mention Whiteco’s constitutional claims and contains no "express determination that there is no just reason for delay and ... express direction for the entry of judgment,” as required by Rule 54(b), Ariz.R.Civ.P., 16 A.R.S. Therefore, the judgment on its face appears to be nonappealable. See A.R.S. § 12-2101;
Stevens v. Mehagian's Home Furnishings, Inc.,
. Although it does not expressly grant cities authority to regulate outdoor lighting, A.R.S. § 49-1106, first enacted in 1986 and dealing with light pollution, states: "The provisions of this article are cumulative and supplemental and shall not apply within any county, city or town which by ordinance or resolution has adopted provisions restricting light pollution which are equal to or more stringent than the provisions of this chapter.” Similarly, A.R.S. § 9-276(A)(24), first enacted in 1973, permits cities to "[a]dopt and enforce standards for shielding and filtration of commercial or public outdoor portable or permanent light fixtures in proximity to astronomical or meteorological laboratories.”
. Because the law and public policy not only disfavor nonconforming uses but also favor their eventual elimination, we strictly construe § 9-462.02 against Whiteco’s interests.
