MR. JUSTICE POWELL delivered the opinion of the Court.

Petitioners, various organizations and individuals resident in the Rochester, N. Y., metropolitan area, brought this action in the District Court for the Western District of New York against the town of Penfield, an incorporated municipality adjacent to Rochester, and against members of Penfield's Zoning, Planning, and Town Boards. Petitioners claimed that the town's zoning ordinance, by its terms and as enforced by the defendant board members, respondents here, effectively excluded persons of low and moderate income from living in the town, in contravention of petitioners' First, Ninth, and Fourteenth Amendment rights and in violation of 42 U.S.C. 1981, 1982, and 1983....

Petitioners' complaint alleged that Penfield's zoning ordinance, adopted in 1962, has the purpose and effect of excluding persons of low and moderate income from residing in the town. In particular, the ordinance allocates 98% of the town's vacant land to single-family detached housing, and allegedly by imposing unreasonable requirements relating to lot size, setback, floor area, and habitable space, the ordinance increases the cost of single-family detached housing beyond the means of persons of low and moderate income.... Petitioners also alleged that "in furtherance of a policy of exclusionary zoning," the defendant members of Penfield's Town, Zoning, and Planning Boards had acted in an arbitrary and discriminatory manner: they had delayed action on proposals for low- and moderate-cost housing for inordinate periods of time; denied such proposals for arbitrary and insubstantial reasons; refused to grant necessary variances and permits, or to allow tax abatements; failed to provide necessary support services for low- and moderate-cost housing projects; and had amended the ordinance to make approval of such projects virtually impossible.

In sum, petitioners alleged that, in violation of their "rights, privileges and immunities secured by the Constitution and laws of the United States," id., at 17, the town and its officials had made "practically and economically impossible the construction of sufficient numbers of low and moderate income . . . housing in the Town of Penfield to satisfy the minimum housing requirements of both the Town of Penfield and the metropolitan Rochester area. . . ." Petitioners alleged, moreover, that by precluding low- and moderate-cost housing, the town's zoning practices also had the effect of excluding persons of minority racial and ethnic groups, since most such persons have only low or moderate incomes.

Petitioners further alleged certain harm to themselves. The Rochester property owners and taxpayers - Vinkey, Reichert, Warth, Harris, and Ortiz - claimed that because of Penfield's exclusionary practices, the city of Rochester had been forced to impose higher tax rates on them and others similarly situated than would otherwise have been necessary. The low- and moderate-income, minority plaintiffs - Ortiz, Broadnax, Reyes, and Sinkler - claimed that Penfield's zoning practices had prevented them from acquiring, by lease or purchase, residential property in the town, and thus had forced them and their families to reside in less attractive environments. To relieve these various harms, petitioners asked the District Court to declare the Penfield ordinance unconstitutional, to enjoin the defendants from enforcing the ordinance, to order the defendants to enact and administer a new ordinance designed to alleviate the effects of their past actions, and to award $750,000 in actual and exemplary damages....

On May 2, 1972, petitioner Rochester Home Builders Association, an association of firms engaged in residential construction in the Rochester metropolitan area, moved the District Court for leave to intervene as a party-plaintiff. It claimed that these practices arbitrarily and capriciously had prevented its member firms from building low- and moderate-cost housing in Penfield, and thereby had deprived them of potential profits.....
 

Apart from this minimum constitutional mandate, this Court has recognized other limits on the class of persons who may invoke the courts' decisional and remedial powers. First, the Court has held that when the asserted harm is a "generalized grievance" shared in substantially equal measure by all or a large class of citizens, that harm alone normally does not warrant exercise of jurisdiction.  Second, even when the plaintiff has alleged injury sufficient to meet the "case or controversy" requirement, this Court has held that the plaintiff generally must assert his own legal rights and interests, and cannot rest his claim to relief on the legal rights or interests of third parties. Without such limitations - closely related to Art. III concerns but essentially matters of judicial self-governance - the courts would be called upon to decide abstract questions of wide public significance even though other governmental institutions may be more competent to address the questions and even though judicial intervention may be unnecessary to protect individual rights....
 

But the fact that these petitioners share attributes common to persons who may have been excluded from residence in the town is an insufficient predicate for the conclusion that petitioners themselves have been excluded, or that the respondents' assertedly illegal actions have violated their rights. Petitioners must allege and show that they personally have been injured, not that injury has been suffered by other, unidentified members of the class to which they belong and which they purport to represent. Unless these petitioners can thus demonstrate the requisite case or controversy between themselves personally and respondents, "none may seek relief on behalf of himself or any other member of the class"....

In their complaint, petitioners Ortiz, Reyes, Sinkler, and Broadnax alleged in conclusory terms that they are among the persons excluded by respondents' actions. None of them has ever resided in Penfield; each claims at least implicitly that he desires, or has desired, to do so. Each asserts, moreover, that he made some effort, at some time, to locate housing in Penfield that was at once within his means and adequate for his family's needs. Each claims that his efforts proved fruitless.  We may assume, as petitioners allege, that respondents' actions have contributed, perhaps substantially, to the cost of housing in Penfield. But there remains the question whether petitioners' inability to locate suitable housing in Penfield reasonably can be said to have resulted, in any concretely demonstrable way, from respondents' alleged constitutional and statutory infractions. Petitioners must allege facts from which it reasonably could be inferred that, absent the respondents' restrictive zoning practices, there is a substantial probability that they would have been able to purchase or lease in Penfield and that, if the court affords the relief requested, the asserted inability of petitioners will be removed.....

We find the record devoid of the necessary allegations. As the Court of Appeals noted, none of these petitioners has a present interest in any Penfield property; none is himself subject to the ordinance's strictures; and none has ever been denied a variance or permit by respondent officials. Instead, petitioners claim that respondents' enforcement of the ordinance against third parties - developers, builders, and the like - has had the consequence of precluding the construction of housing suitable to their needs at prices they might be able to afford....

Here, by their own admission, realization of petitioners' desire to live in Penfield always has depended on the efforts and willingness of third parties to build low- and moderate-cost housing. The record specifically refers to only two such efforts: that of Penfield Better Homes Corp., in late 1969, to obtain the rezoning of certain land in Penfield to allow the construction of subsidized cooperative townhouses that could be purchased by persons of moderate income; and a similar effort by O'Brien Homes, Inc., in late 1971. But the record is devoid of any indication that these projects, or other like projects, would have satisfied petitioners' needs at prices they could afford, or that, were the court to remove the obstructions attributable to respondents, such relief would benefit petitioners. Indeed, petitioners' descriptions of their individual financial situations and housing needs suggest precisely the contrary - that their inability to reside in Penfield is the consequence of the economics of the area housing market, rather than of respondents' assertedly illegal acts. In short, the facts alleged fail to support an actionable causal relationship between Penfield's zoning practices and petitioners' asserted injury.

We hold that a plaintiff who seeks to challenge exclusionary zoning practices must allege specific, concrete facts demonstrating that the challenged practices harm him, and that he personally would benefit in a tangible way from the court's intervention.
 

Petitioners do not, even if they could, assert any personal right under the Constitution or any statute to be free of action by a neighboring municipality that may have some incidental adverse effect on Rochester. On the contrary, the only basis of the taxpayer-petitioners' claim is that Penfield's zoning ordinance and practices violate the constitutional and statutory rights of third parties, namely persons of low and moderate income who are said to be excluded from Penfield. In short the claim of these petitioners falls squarely within the prudential standing rule that normally bars litigants from asserting the rights or legal interests of others in order to obtain relief from injury to themselves. As we have observed above, this rule of judicial self-governance is subject to exceptions, the most prominent of which is that Congress may remove it by statute....
 

Metro-Act does not assert on behalf of its members any right of action under the 1968 Civil Rights Act, nor can the complaint fairly be read to make out any such claim....

Even if we assume, arguendo, that apart form any statutorily created right the asserted harm to Metro-Act's Penfield members is sufficiently direct and personal to satisfy the case-or-controversy requirement of Art. III, prudential considerations strongly counsel against according them or Metro-Act standing to prosecute this action. We do not understand Metro-Act to argue that Penfield residents themselves have been denied any constitutional rights, affording them a cause of action under 42 U.S.C. 1983. Instead, their complaint is that they have been harmed indirectly by the exclusion of others. This is an attempt to raise putative rights of third parties, and none of the exceptions that allow such claims is present here. In these circumstances, we conclude that it is inappropriate to allow Metro-Act to invoke the judicial process....

Petitioner Home Builders, in its intervenor-complaint, asserted standing to represent its member firms engaged in the development and construction of residential housing in the Rochester area, including Penfield. Home Builders alleged that the Penfield zoning restrictions, together with refusals by the town officials to grant variances and permits for the construction of low- and moderate-cost housing, had deprived some of its members of "substantial business opportunities and profits."

Here an association seeks relief in damages for alleged injuries to its members. Home Builders alleges no monetary injury to itself, nor any assignment of the damages claims of its members. No award therefore can be made to the association as such. Moreover, in the circumstances of this case, the damages claims are not common to the entire membership, nor shared by all in equal degree. To the contrary, whatever injury may have been suffered is peculiar to the individual member concerned, and both the fact and extent of injury would require individualized proof. Thus, to obtain relief in damages, each member of Home Builders who claims injury as a result of respondents' practices must be a party to the suit, and Home Builders has no standing to claim damages on his behalf....A like problem is presented with respect to petitioner Housing Council....

The exception is the Penfield Better Homes Corp. As we have observed above, it applied to respondents in late 1969 for a zoning variance to allow construction of a housing project designed for persons of moderate income. The affidavit in support of the motion to join Housing Council refers specifically to this effort, and the supporting materials detail at some length the circumstances surrounding the rejection of Better Homes' application. It is therefore possible that in 1969, or within a reasonable time thereafter, Better Homes itself and possibly Housing Council as its representative would have had standing to seek review of respondents' action. The complaint, however, does not allege that the Penfield Better Homes project remained viable in 1972 when this complaint was filed, or that respondents' actions continued to block a then-current construction project. In short, neither the complaint nor the record supplies any basis from which to infer that the controversy between respondents and Better Homes, however vigorous it may once have been, remained a live, concrete dispute when this complaint was filed....

MR. JUSTICE DOUGLAS, dissenting.

With all respect, I think that the Court reads the complaint and the record with antagonistic eyes. There are in the background of this case continuing strong tides of opinion touching on very sensitive matters, some of which involve race, some class distinctions based on wealth....

Standing has become a barrier to access to the federal courts, just as "the political question" was in earlier decades. The mounting caseload of federal courts is well known. But cases such as this one reflect festering sores in our society; and the American dream teaches that if one reaches high enough and persists there is a forum where justice is dispensed. I would lower the technical barriers and let the courts serve that ancient need. They can in time be curbed by legislative or constitutional restraints if an emergency arises....

MR. JUSTICE BRENNAN, with whom MR. JUSTICE WHITE and MR. JUSTICE MARSHALL join, dissenting.

The Court today, in an opinion that purports to be a "standing" opinion but that actually, I believe, has overtones of outmoded notions of pleading and of justiciability, refuses to find that any of the variously situated plaintiffs can clear numerous hurdles, some constructed here for the first time, necessary to establish "standing." While the Court gives lip service to the principle, oft repeated in recent years, that "standing in no way depends on the merits of the plaintiff's contention that particular conduct is illegal," in fact the opinion, which tosses out of court almost every conceivable kind of plaintiff who could be injured by the activity claimed to be unconstitutional, can be explained only by an indefensible hostility to the claim on the merits. I can appreciate the Court's reluctance to adjudicate the complex and difficult legal questions involved in determining the constitutionality of practices which assertedly limit residence in a particular municipality to those who are white and relatively well off, and I also understand that the merits of this case could involve grave sociological and political ramifications. But courts cannot refuse to hear a case on the merits merely because they would prefer not to, and it is quite clear, when the record is viewed with dispassion, that at least three of the groups of plaintiffs have made allegations, and supported them with affidavits and documentary evidence, sufficient to survive a motion to dismiss for lack of standing....
