Carson Harbor Village Ltd. appeals the dismissal of its complaint alleging that laws regulating mobile home parks in the City of Carson, California violate the Due Process and Takings Clauses of the United States Constitution. We affirm.
I
Carson Harbor Village Ltd. (“Carson Harbor”) owns a mobile home park containing 409 rental spaces in the City of Carson (“city”). Residents of the park own their mobile homes but rent spaces from Carson Harbor. Despite their name, mobile homes are largely immobile. As a practical matter, moving one is expensive and difficult. Once in place, the vast majority of mobile homes are never moved again. 1 If a mobile home owner desires to relocate, he usually sells the mobile home in place and the purchaser rents the space from the park owner.
Since 1978, mobile home park owners in California have been subject to the Mobile Home Residency Law, Cal.Civ.Code § 798 et seq. (“Residency Law”). The Residency Law severely limits the bases upon which a park owner may terminate a mobile home owner’s tenancy. It also prohibits park owners from requiring the removal of a mobile home when it is sold. Park owners cannot charge a transfer fee upon sale, nor can they disapprove a purchaser as long as the purchaser demonstrates an ability to pay the space rental. The Residency Law, however, does not include any rent control provisions.
In 1979, the city passed the Mobilehome Space Rent Control Ordinance (“Rent Control Law”), which sets a maximum ceiling on rent levels that can be charged for a space in mobile home parks. Carson, Cal., Ordinance 79-485U (May 20, 1979); Carson, Cal., Municipal Code, art. TV, ch. 7, § 4700 et seq. The Rent Control Law also contains a provision prohibiting park owners from increasing *471 rents upon termination of a tenancy or sale of a mobile home. It also establishes the Mobilehome Park Rental Review Board (“Review Board”) to hear claims for increases above the ceiling. The Review Board’s decisions are guided by a set of policy guidelines adopted by the Carson City Council. The Rent Control Law makes legislative findings that park tenants face a “low vacancy rate and rapidly rising space rents” and that the “purchase of a mobile[]home involves a substantial investment, and its relocation is expensive and difficult.” Carson, Cal., Ordinance 79-485U, Sec. 2, (May 20, 1979). As the findings suggest, and as the city argues on appeal, the Rent Control Law’s purpose is to mitigate rising rents and to protect tenants from losing their investments if they sell their mobile homes.
In 1982, the city supplemented the Rent Control Law with an ordinance requiring park owners to obtain city approval before converting mobile home parks to other uses or vacant lots. Carson, Cal., Ordinance 82-589U (Mar. 8,1982); Carson, Cal., Municipal Code art. IX, eh. 1, pt. 2, div. 8, § 9128.21. Later in 1982, the city passed another ordinance which, among other things, grants the city the power to require a park owner to bear the costs of relocating tenants to another park, reimburse tenants for the on-site value of their coaches, or set aside a certain number of units for park tenants, in the event the park is closed or converted to another use. Carson, Cal., Ordinance 82-618 (Sept. 20, 1982). Together, these two ordinances constitute the Conversion Law. The stated purpose of the Conversion Law is to “minimize the impact [park] closures ... will have on park residents and to provide assistance to park residents in relocating.” Carson, Cal., Municipal Code, art. IX, eh. 1, pt. 2, div. 8, § 9128.21.
Carson Harbor purchased Carson Harbor Village Mobile Home Park on March 31, 1983, after enactment of the Rent Control and Conversion Laws. On January 30,1989, Carson Harbor, pursuant to the Rent Control Law, applied to the City of Carson’s Community Development Department for an increase in rent above the ceiling. On October 19, 1989, after a hearing before the Review Board, the city granted the request only in part.
On July 2, 1990, Carson Harbor filed suit in district court alleging that the Rent Control Law and Conversion Law are unconstitutional. In its complaint, Carson Harbor asserted claims under the Takings and Due Process Clauses of the United States Constitution, and Art. I, § 19 of the California Constitution. 2
The district court dismissed the entire complaint, concluding: (1) the due process claim failed to state a claim under Fed. R.CÍV.P. 12(b)(6), (2) the takings claims based on the Rent Control Law were not ripe for federal adjudication, and (3) the takings claim based on the Conversion Law was not ripe and also failed to state a claim under Fed.R.Civ.P. 12(b)(6). The district court' also concluded it lacked pendant jurisdiction to hear the state-law inverse condemnation claim, since the federal claims had been dismissed. Carson Harbor timely appeals from dismissal of the complaint. 3
*472 II
Carson Harbor contests the district court’s dismissal of its substantive due process claim for failure to state a claim. We review
de novo
a district court’s Rule 12(b)(6) dismissal.
Oscar v. University Students Cooperative Ass’n,
Carson Harbor’s substantive due process claim is based on the Rent Control Law which prohibits park owners from increasing rent during a tenancy and at the termination of a tenancy. Carson Harbor alleges that Rent Control Law, when acting in concert with the California Mobile Home Residency Law’s restrictions on tenancy terminations, has the effect of permitting tenants to occupy the spaces at below-market rents for an unlimited time. When a mobile home tenant sells his home, the seller can charge the buyer a premium for this right over and above the normal market value of the home itself. This premium, Carson Harbor alleges, is a “windfall” to selling tenants. Carson Harbor alleges that the prohibition on rent increases at the termination of a tenancy violates due process because it bears no rational relationship to preventing excessive rents for selling tenants, and because the law “does nothing” to preserve low or moderate income housing.
A generally applicable rent-control ordinance will survive a substantive due process challenge if it is
“designed
to accomplish an objective within the government’s police power, and if a rational relationship existed between, the provisions and the purpose of the ordinances.”
Boone v. Redevelopment Agency of San Jose,
In examining the sufficiency of the complaint, we assume that the facts contained in Carson Harbor’s pleadings are true. Carson Harbor’s pleadings incorporate the text of the statute. As noted previously, the apparent purpose of the ordinance is to mitigate hardships caused by rising rents and to protect the tenants’ investments in their mobile homes if they choose to sell. We are free to examine the face of the statute and determine whether, in light of its purposes, Carson Harbor is able to prove any set of facts in support of its claim.
See Boone,
We hold that Carson Harbor has failed to state a claim upon which relief can be granted. Carson Harbor’s own pleadings állege that the transfer of the premium grants a “windfall” to tenants who sell. In light of this admission, we have no difficulty concluding that a rational legislator could have believed that the prohibition of rent increases at the termination of a tenancy would further the law’s goals, at least insofar as the purpose is to protect the investments of existing tenants. As we have stated before in rejecting a similar claim:
[A] rational legislator could have believed that the unfettered right of a park owner to raise the rent on a space when ownership of a mobile home was transferred might make it difficult for a mobile home owner to sell. The legislator thus could have believed that the ordinance protects owners’ investments in their units.
Levald, Inc. v. City of Palm Desert,
Ill
The Takings Clause of the Fifth Amendment provides: “[N]or shall property be taken for public use, without just compensation.” There are two classes of Fifth Amendment takings recognized by the Supreme Court: physical takings and regulatory takings.
Compare Loretto v. Teleprompter Manhattan CATV Corp.,
Carson Harbor argues that the Rent Control Law and the Conversion law are regulatory takings. A regulatory taking may be challenged in two ways: through a “facial” challenge or an “as-applied” challenge. “A facial challenge involves ‘a claim
*474
that the mere enactment of a statute constitutes a taking,’ while an as-applied challenge involves ‘a claim that the particular impact of a government action on a specific piece of property requires the payment of just compensation.’ ”
Levald,
A
Carson Harbor raises two as-applied taking claims. 5 First, it claims that the Review Board’s partial denial of a request for a rent increase constitutes an as-applied taking because it prevents Carson Harbor from meeting its operating expenses and realizing a reasonable profit. Second, it claims that the Conversion Law’s provisions allowing the city to impose on park owners the costs of relocating tenants in the event of closure or conversion of a park is “confiscatory” and constitutes an as-applied taking.
The district court concluded that neither as-applied claim was ripe for federal adjudication under the two-part rule established in
Williamson County Regional Planning Comm’n v. Hamilton Bank,
In
Williamson,
the Supreme Court placed two independent hurdles to the filing of a taking claim in federal court against a state or local government. The first requires that before filing suit, the claimant seek a final decision from the government entity regarding the application of the regulation to the property at issue.
Id.
at 186,
The second hurdle established by
Williamson
requires a claimant to “ ‘seek compensation through the procedures the State has provided for doing so’ before turning to the federal courts.”
Sinaloa Lake Owner’s Ass’n v. City of Simi Valley,
Carson Harbor’s claim involving the application of the rent control law unquestionably meets
Williamson’s
first ripeness hurdle. Carson Harbor made a “meaningful application” for a variance from the rent control law by submitting an application for a rent increase in October, 1989, which the Review Board partially denied. The district court, however, concluded that Carson Harbor had failed to meet the second ripeness hurdle because a remedy for regulatory takings through a claim of inverse condemnation was available in California in October, 1989. The remedy has been available since 1987, when the Supreme Court ruled in
First English Evangelical Lutheran Church,
Carson Harbor’s other as-applied claim, which challenges the Conversion Law, also is not ripe. Carson Harbor has failed to meet the first hurdle of
Williamson,
which requires a claimant to obtain a final decision regarding the application of the regulation from the governing entity.
See Williamson,
B
Carson Harbor also raises two facial takings claims. First, Carson Harbor claims that the Rent Control Law constitutes a taking by allowing the mobile home tenants to capture the premium, which, Carson Harbor argues, belongs to park owners. As noted, we construe this claim as a facial challenge. 6 Second, Carson Harbor claims that the Conversion Law is a facial taking because the law interferes with the right to dispose of property. As part of the second facial claim, Carson Harbor also claims that the Conversion Law is “unconstitutional” on its face, and seeks a favorable declaratory judgment.
We first address whether Carson Harbor has standing to litigate its facial claims. Because standing is a necessary element of federal jurisdiction, we raise the issue of standing
sua sponte. See City of South Lake Tahoe v. California Tahoe Regional Planning Agency,
Article III limits the judicial power of the federal courts to “cases” and “controversies.” “[A]t an irreducible minimum, Art. Ill requires the party who invokes the court’s authority to ‘show that he personally has suffered some actual or threatened injury as a result of the putatively illegal conduct of the defendant’_”
Valley Forge Christian College v. Americans United for Separation of Church and State, Inc.,
In determining Carson Harbor’s standing to assert facial claims, we “ ‘accept as true all material allegations in the complaint’ and ‘construe the complaint in favor of the complaining party.’ ”
Pennell v. San Jose,
Both facial claims necessarily rest on the premise that an interest in property was taken from all mobile home property owners upon the statute’s enactment. Given this premise, Carson Harbor has suffered no “actual injury.” In a facial taking, the harm , is singular and discrete, occurring
only
at the time the statute is enacted.
See Levald,
In the takings context, the basis of a facial challenge is that the very enactment of the statute has reduced the value of the property or has effected a transfer of a property interest. This is a single harm, measurable and compensable when the statute is passed.
Levald,
We note that Carson Harbor’s facial claim against the Rent Control Law also alleges that the law “does not substantially advance any legitimate government interest.” Under this theory of takings, the law is invalid if the required dedication of property is unrelated in nature, or disproportionate in extent, to the problem that the government seeks to mitigate or control.
See Dolan v. City of Tigard,
— U.S.-,-,

Carson Harbor argues that the district court erred in declining to exercise pendent jurisdiction over its state inverse condemnation claims. The existence of an actionable federal claim is a prerequisite to pendent jurisdiction.
United Mine Workers v. Gibbs,
V
The substantive due process claim fails to state a claim upon which relief can be granted, the as-applied takings claims are not ripe, and Carson Harbor lacks standing to pursue a facial takings claim.
AFFIRMED.

If the regulation “denies an owner economically viable use of his land,” an inquiry into the state interest advanced in support of the regulation is not required.

. In its complaint, Carson Harbor alleges that the Rent Control Law also effected a physical taking by allowing mobile home tenants to capture the premium which, Carson Harbor argues, belongs to the park owner. The subsequent decision in
Yee v. City of Escondido,
— U.S. -,
Carson Harbor, however, further attempts to challenge the transfer of the premium in an as-applied takings claim. We reject the notion that it constitutes an as-applied claim. In
Levald,
which involved similar facts, we noted that the premium is "relevant only to a facial, not an as-applied, regulatoiy challenge. It is not a particular application of the statute that gives rise to the premium; the premium arises solely from the existence of the statute itself."
Levald,
. See supra note 5.
. In non-taking contexts, the harm is continuing or does not occur until the statute “is enforced,!’ and consequently the Supreme Court has allowed non-taking challenges to statutes “long after they were enacted.”
Levald,
. We recognize that a landowner may suffer injury when, pursuant to the rent control ordinance, the city denies a rent increase. However, this injury is relevant only in the context of an as-applied takings claim. Carson Harbor has raised an as-applied claim but, as we have noted, the claim is not ripe.
