*1004 OPINION
Thе Small Property Owners of San Francisco Institute (“SPOSFI”) and Mary Figone appeal the district court’s judgment rejecting their facial First Amendment and vagueness challenges to portions of “Proposition M,” a popularly enacted amendment to the rent-stabilization ordinance of the City and County of San Francisco (“the City”). Because we conclude that both SPOSFI and Figone lack standing, we cannot reach the merits of their challenges. Instead, we vacate the district court’s judgment and remand with instructions to dismiss the complaint for lack of subject-matter jurisdiction.
I
San Francisco vоters approved Proposition M in November 2008. As pertinent here, the proposition amended the City’s rent-stabilization ordinance to prohibit residential landlords and their agents from attempting, “in bad faith,” to “coerce the tenant to vacate with offers of payments to vacаte which are accompanied with threats or intimidation.” S.F. Admin. Code § ST.lOBiaXO). 1
SPOSFI is a nonprofit association of approximately 1,500 residential landlords in San Francisco. In February 2009, it filed suit in the district court, seeking declaratory relief and a permanent injunction barring enforcement of parts of Proposition M. The association was joined by Tim Carrico, an individual landlord who is not a party to this appeal. Figone, another individual landlord, joined the suit in May of that year.
As set forth in their amended complaint, the plaintiffs raised three federal constitutional challenges. First, they alleged that § 37.10B(a)(6) violated the Free Speech and Petition Clauses of the First Amendment, made applicable to the City by the Fourteenth Amendment. Second, they alleged that § 37.10B(a)(6) failed to provide adequate notice of prohibited conduct in violation of the Due Process Clause of the Fourteenth Amendment. Third, they argued that deficiencies in the presentation of Proposition M on the ballot violated substantive due process. They also raised several state-law challenges. Rather than claiming that the proposition was invalid only as applied to them, the plaintiffs argued that it was invalid on its face.
The City moved to dismiss the substantive due process challenge pursuant to Federal Rule of Civil Procedure 12(b)(6). The district court agreed and dismissed that claim with prejudice. That ruling has not been appealed.
At the same time, the district court issued аn order to show cause why the remaining federal claims — that is, the First Amendment and vagueness challenges — should not be dismissed as “moot or insubstantial.” After hearing argument and considering the parties’ written responses to the show-cause order, the district court issued a twelve-page order dismissing the rеmaining federal claims.
The district court concluded that § 37.10B(a)(6) implicated only commercial speech, but not just commercial speech that was misleading or connected to unlawful activity. Accordingly, it applied the
*1005
test announced in
Central Hudson Gas & Electric Corp. v. Public Service Commission,
Turning to the vagueness challenge, the district court held that bad faith “enjoys such common usage as to overcome any vagueness concеrns,” and that the other challenged terms threats, intimidation and offers of payment — “have meanings that a person of ordinary intelligence would understand.” Finally, the court held that plaintiffs could not make out a facial challenge to Proposition M as an unconstitutional burden on their right to petition because § 37.10(a)(6) could be applied in many cases that did not implicate that right.
Having dismissed all of the federal claims, the district court declined to exercise supplemental jurisdiction, which is discretionary, over the state-law challenges. This appeal followed.
Although the City did not challenge appellаnts’ standing either in the district court or before us, we raised the issue
nostra sponte
at oral argument.
See Stormans, Inc. v. Selecky,
II
To establish “the irreducible constitutional minimum of standing,” a plaintiff invoking federal jurisdiction must establish “injury in fact, causation, and a likelihood that a favorable decision will redress the plaintiffs alleged injury.”
Lopez v. Candaele,
Plaintiffs in First Amendment cases may satisfy the injury-in-fact requirement without actually engaging in claimed protected speech.
See Arizona Right to Life Political Action Comm. v. Bayless,
The same rules apply to plaintiffs bringing facial challenges and invoking the speech of others under the overbreadth doctrine.
See Dream Palace v. County of Maricopa,
In concluding that particular “pre-enforcement plaintiffs” have failed to establish standing, we have relied on “three related inquiries”:
First, we have considered whether preenforcement plaintiffs have failed to show a reasonable likelihood thаt the government will enforce the challenged law against them. Second, we have considered whether the plaintiffs have failed to establish, with some degree of concrete detail, that they intend to violate the challenged law. We have also considered a third factоr, whether the challenged law is inapplicable to the plaintiffs, either by its terms or as interpreted by the government. Such inapplicability weighs against both the plaintiffs’ claims that they intend to violate the law, and also their claims that the government intends to enforce the law against them.
Lopez,
A plaintiff must establish standing with the “manner and degree of evidence required at the successive stages of the litigation.”

Appellants alleged, without further elaboration, that “Proposition M was intended to, and does, impact their operations as landlords.” This conelusory allegation is insufficient to establish standing.
See Lopez,
Appellants further alleged that they “are subject to the legal and constitutional infirmities of the municipal ordinance.” Citing
Pennell v. City of San Jose,
At issue in
Pennell
was an ordinance allowing city officials to take into account “hardship to a tenant” in determining whether a landlord’s proposed rent increase was reasonable.

S.Ct. 849. As in the present case, an individual landlord and an association akin to SPOSFI sued to enjoin еnforcement of the ordinance.
See id.
at 6,
Contrary to appellants’ contention, the Supreme Court did not find standing based solely on the allegation that the plaintiffs were “subject to the terms of’ the ordinance; it also noted the association’s statement at oral argument that it reprеsented “most of the residential unit owners in the city and [had] many hardship tenants.”

Here, by contrast, there is no allegation on which to base an inference that any of SPOSFI’s members intend to engage in conduct even arguably proscribed by Proposition M. As a matter of common sense, an allegation that a plaintiff is “subject to” the challenged ordinance cannot suffice. The plaintiff in Lopez, a college student, was undoubtedly “subject to” his college’s antiharassment policy. We nevertheless held that he could not establish even a threat of being punished for violating the policy.
As the Supreme Court observed in
Pennell,
“application of the constitutional standing requirement's not] a mechaniсal exercise.”
This failing pervades the three inquiries identified in Lopez. Without any description of intended speech or conduct, we cannot analyze what SPOSFI’s members would like to do. We, therefore, cannot analyze whether what they would like to do even arguably falls within the scope of Proposition M. And, therefore, we cannot analyze whether they face a credible threat of prosecution by the City. Indeed, without more, we cannot even analyze whether what SPOSFI’s members want to do is protected by the First Amendment in the first place.
In sum, SPOSFI has not demonstrated that its members have “an intention to engage in a course of conduct arguably affeсted with a constitutional interest,” that what they wish to do is “proscribed by [Proposition M],” or that they face “a credible threat of prosecution thereunder.”
Babbitt,
Unlike SPOSFI, Figone at least alleged a concrete example of Proposition M’s effect on her. She alleged that she bеcame embroiled in a dispute with a sub *1008 tenant of a former tenant who continued to claim a valid tenancy after the main tenant’s lease expired. The subtenant sued, claiming that Figone’s “communications regarding his status, threats to invoke legal process to resolve the situation, hеr subsequent lawsuit itself, and even her refusal to accept his rent pending resolution violated Proposition M.”
Nevertheless, Figone’s allegations are insufficient for two reasons. First, since she did not allege that she offered the subtenant payment to vacate, she has not demonstrated that her conduct is even “arguably ... proscribed,”
Babbitt,
In sum, we hold that appellants’ allegations, as they now stand, are insufficient to confer standing. We therefore pass to the question of whether we should allow appellants leave to amend them.
IV
A court should “freely give leave [to amend] when justice so requires.” Fed.R.Civ.P. 15(a)(2). It is prоperly denied, however, if amendment would be futile.
See Gordon v. City of Oakland,
Appellants’ principal argument is that the allegations of their amended complaint are sufficient to confer standing. They seek leave to amend only as an afterthought. Moreover, they do not, in their post-argument submissions, propose any specific allegations that might rectify their failure to identify any arguably prohibited speech or conduct in which they would otherwise engage. We take that as a demonstration of their inability (or, perhaps, unwillingness) to make the necessary amendment. Accordingly, we deny leave to amend as futile.
Instead, we
VACATE AND REMAND WITH INSTRUCTIONS TO DISMISS FOR LACK OF JURISDICTION.
Notes
. In a state-court challenge, the California Court of Appeal, First District, invalidated other parts of Proposition M, including a companion provision prohibiting "[c]ontinu[ing] to offer payments to vacate after tenant has notified the landlord in writing that they no longer wish to receive further offers of payments to vacate.”
See Larson v. City & County of
S.F.,
. “Associational standing” also requires a showing that “the interests the suit seeks to vindicate are germane to the organization’s purpose,” and that “neither the claim аsserted nor the relief requested requires the participation of individual members in the lawsuit.”
Fleck & Assocs.,
. Having held that the association had standing, the Court did not address whether the individual landlord did as well.
See Pennell,
. Figone’s allegations do not convert her facial chаllenge into an as-applied one. Had she wished to remedy the effect of Proposition M on her subtenant’s suit, she would have named him as a party and sought a declaratory judgment and/or injunctive relief binding him. Instead, the only entity bound by a judgment favorable to Figone in this case would be the City. Thus, the relief Figone seeks would not remedy her claimed injury.
