Appellant was charged with violating the San Francisco Housing Code for refusing, after three efforts by city housing inspectors to secure his consent, to allow a warrantless inspection of the ground-floor quarters which he leased and residential use of which allegedly violated the apartment building's occupancy permit. Claiming the inspection ordinance unconstitutional for failure to require a warrant for inspections, appellant while awaiting trial sued in a State Superior Court for a writ of prohibition, which the court denied. Relying on Frank v. Maryland, 359 U.S. 360 , and similar cases, the District Court of Appeal affirmed, holding that the ordinance did not violate the Fourth Amendment. The State Supreme Court denied a petition for hearing. Held:

MR. JUSTICE WHITE delivered the opinion of the Court.
In Frank v. Maryland, 359 U.S. 360 , this Court upheld, by a five-to-four vote, a state court conviction of a home-owner who refused to permit a municipal health inspector to enter and inspect his premises without a search warrant. In Eaton v. Price, 364 U.S. 263 , a similar conviction was affirmed by an equally divided Court. Since those closely divided decisions, more intensive efforts at all levels of government to contain and eliminate urban blight have led to increasing use of such inspection techniques, while numerous decisions of this Court have more fully defined the Fourth Amendment's effect on state and municipal action. E. g., Mapp v. Ohio, 367 U.S. 643 ; Ker v. California, 374 U.S. 23 . In view of the growing nationwide importance of the problem, we noted probable jurisdiction in this case and in See v. City of Seattle, post, p. 541, to re-examine whether administrative inspection programs, as presently authorized and conducted, violate Fourth Amendment rights as those rights are enforced against the States through the Fourteenth Amendment. 385 U.S. 808 .
Appellant brought this action in a California Superior Court alleging that he was awaiting trial on a criminal charge of violating the San Francisco Housing Code by refusing to permit a warrantless inspection of his residence, and that a writ of prohibition should issue to the criminal court because the ordinance authorizing such inspections is unconstitutional on its face. The Superior Court denied the writ, the District Court of Appeal affirmed, and the Supreme Court of California denied a petition for hearing. Appellant properly raised and had considered by the California courts the federal constitutional questions he now presents to this Court.
Though there were no judicial findings of fact in this prohibition proceeding, we shall set forth the parties' factual allegations. On November 6, 1963, an inspector [387 U.S. 523, 526] of the Division of Housing Inspection of the San Francisco Department of Public Health entered an apartment building to make a routine annual inspection for possible violations of the city's Housing Code. 1 The building's manager informed the inspector that appellant, lessee of the ground floor, was using the rear of his leasehold as a personal residence. Claiming that the building's occupancy permit did not allow residential use of the ground floor, the inspector confronted appellant and demanded that he permit an inspection of the premises. Appellant refused to allow the inspection because the inspector lacked a search warrant.
The inspector returned on November 8, again without a warrant, and appellant again refused to allow an inspection. A citation was then mailed ordering appellant to appear at the district attorney's office. When appellant failed to appear, two inspectors returned to his apartment on November 22. They informed appellant that he was required by law to permit an inspection under 503 of the Housing Code:
Appellant has argued throughout this litigation that 503 is contrary to the Fourth and Fourteenth Amendments in that it authorizes municipal officials to enter a private dwelling without a search warrant and without probable cause to believe that a violation of the Housing Code exists therein. Consequently, appellant contends, he may not be prosecuted under 507 for refusing to permit an inspection unconstitutionally authorized by 503. Relying on Frank v. Maryland, Eaton v. Price, and decisions in other States, 3 the District [387 U.S. 523, 528] Court of Appeal held that 503 does not violate Fourth Amendment rights because it "is part of a regulatory scheme which is essentially civil rather than criminal in nature, inasmuch as that section creates a right of inspection which is limited in scope and may not be exercised under unreasonable conditions." Having concluded that Frank v. Maryland, to the extent that it sanctioned such warrantless inspections, must be overruled, we reverse.
Though there has been general agreement as to the fundamental purpose of the Fourth Amendment, translation of the abstract prohibition against "unreasonable searches and seizures" into workable guidelines for the decision of particular cases is a difficult task which has for many years divided the members of this Court. Nevertheless, one governing principle, justified by history and by current experience, has consistently been followed: except in certain carefully defined classes of cases, a search of private property without proper consent [387 U.S. 523, 529] is "unreasonable" unless it has been authorized by a valid search warrant. See, e. g., Stoner v. California, 376 U.S. 483 ; United States v. Jeffers, 342 U.S. 48 ; McDonald v. United States, 335 U.S. 451 ; Agnello v. United States, 269 U.S. 20 . As the Court explained in Johnson v. United States, 333 U.S. 10, 14 :
To the Frank majority, municipal fire, health, and housing inspection programs "touch at most upon the periphery of the important interests safeguarded by the Fourteenth Amendment's protection against official intrusion," 359 U.S., at 367 , because the inspections are merely to determine whether physical conditions exist which do not comply with minimum standards prescribed in local regulatory ordinances. Since the inspector does not ask that the property owner open his doors to a search for "evidence of criminal action" which may be used to secure the owner's criminal conviction, historic interests of "self-protection" jointly protected by the Fourth and Fifth Amendments 5 are said not to be involved, but only the less intense "right to be secure from intrusion into personal privacy." Id., at 365.
We may agree that a routine inspection of the physical condition of private property is a less hostile intrusion than the typical policeman's search for the fruits and instrumentalities of crime. For this reason alone, Frank differed from the great bulk of Fourth Amendment cases which have been considered by this Court. But we cannot agree that the Fourth Amendment interests at stake in these inspection cases are merely "peripheral." It is surely anomalous to say that the individual and his private property are fully protected by the Fourth Amendment only when the individual is suspected of criminal behavior. 6 For instance, even the most law-abiding citizen [387 U.S. 523, 531] has a very tangible interest in limiting the circumstances under which the sanctity of his home may be broken by official authority, for the possibility of criminal entry under the guise of official sanction is a serious threat to personal and family security. And even accepting Frank's rather remarkable premise, inspections of the kind we are here considering do in fact jeopardize "self-protection" interests of the property owner. Like most regulatory laws, fire, health, and housing codes are enforced by criminal processes. In some cities, discovery of a violation by the inspector leads to a criminal complaint. 7 Even in cities where discovery of a violation produces only an administrative compliance order, 8 refusal to comply is a criminal offense, and the fact of compliance is verified by a second inspection, again without a warrant. 9 Finally, as this case demonstrates, refusal to permit an inspection is itself a crime, punishable by fine or even by jail sentence.
The Frank majority suggested, and appellee reasserts, two other justifications for permitting administrative health and safety inspections without a warrant. First, it is argued that these inspections are "designed to make the least possible demand on the individual occupant." 359 U.S., at 367 . The ordinances authorizing inspections are hedged with safeguards, and at any rate the inspector's particular decision to enter must comply with the constitutional standard of reasonableness even if he may enter without a warrant. 10 In addition, the argument [387 U.S. 523, 532] proceeds, the warrant process could not function effectively in this field. The decision to inspect an entire municipal area is based upon legislative or administrative assessment of broad factors such as the area's age and condition. Unless the magistrate is to review such policy matters, he must issue a "rubber stamp" warrant which provides no protection at all to the property owner.
In our opinion, these arguments unduly discount the purposes behind the warrant machinery contemplated by the Fourth Amendment. Under the present system, when the inspector demands entry, the occupant has no way of knowing whether enforcement of the municipal code involved requires inspection of his premises, no way of knowing the lawful limits of the inspector's power to search, and no way of knowing whether the inspector himself is acting under proper authorization. These are questions which may be reviewed by a neutral magistrate without any reassessment of the basic agency decision to canvass an area. Yet, only by refusing entry and risking a criminal conviction can the occupant at present challenge the inspector's decision to search. And even if the occupant possesses sufficient fortitude to take this risk, as appellant did here, he may never learn any more about the reason for the inspection than that the law generally allows housing inspectors to gain entry. The practical effect of this system is to leave the occupant subject to the discretion of the official in the field. This is precisely the discretion to invade private property which we have consistently circumscribed by a requirement that a disinterested party warrant the need to [387 U.S. 523, 533] search. See cases cited, p. 529, supra. We simply cannot say that the protections provided by the warrant procedure are not needed in this context; broad statutory safeguards are no substitute for individualized review, particularly when those safeguards may only be invoked at the risk of a criminal penalty.
The final justification suggested for warrantless administrative searches is that the public interest demands such a rule: it is vigorously argued that the health and safety of entire urban populations is dependent upon enforcement of minimum fire, housing, and sanitation standards, and that the only effective means of enforcing such codes is by routine systematized inspection of all physical structures. Of course, in applying any reasonableness standard, including one of constitutional dimension, an argument that the public interest demands a particular rule must receive careful consideration. But we think this argument misses the mark. The question is not, at this stage at least, whether these inspections may be made, but whether they may be made without a warrant. For example, to say that gambling raids may not be made at the discretion of the police without a warrant is not necessarily to say that gambling raids may never be made. In assessing whether the public interest demands creation of a general exception to the Fourth Amendment's warrant requirement, the question is not whether the public interest justifies the type of search in question, but whether the authority to search should be evidenced by a warrant, which in turn depends in part upon whether the burden of obtaining a warrant is likely to frustrate the governmental purpose behind the search. See Schmerber v. California, 384 U.S. 757, 770 -771. It has nowhere been urged that fire, health, and housing code inspection programs could not achieve their goals within the confines of a reasonable search warrant requirement. Thus, we do not find the public need argument dispositive. [387 U.S. 523, 534]
In summary, we hold that administrative searches of the kind at issue here are significant intrusions upon the interests protected by the Fourth Amendment, that such searches when authorized and conducted without a warrant procedure lack the traditional safeguards which the Fourth Amendment guarantees to the individual, and that the reasons put forth in Frank v. Maryland and in other cases for upholding these warrantless searches are insufficient to justify so substantial a weakening of the Fourth Amendment's protections. Because of the nature of the municipal programs under consideration, however, these conclusions must be the beginning, not the end, of our inquiry. The Frank majority gave recognition to the unique character of these inspection programs by refusing to require search warrants; to reject that disposition does not justify ignoring the question whether some other accommodation between public need and individual rights is essential.
In cases in which the Fourth Amendment requires that a warrant to search be obtained, "probable cause" is the standard by which a particular decision to search is tested against the constitutional mandate of reasonableness. To apply this standard, it is obviously necessary first to focus upon the governmental interest which allegedly justifies official intrusion upon the constitutionally protected [387 U.S. 523, 535] interests of the private citizen. For example, in a criminal investigation, the police may undertake to recover specific stolen or contraband goods. But that public interest would hardly justify a sweeping search of an entire city conducted in the hope that these goods might be found. Consequently, a search for these goods, even with a warrant, is "reasonable" only when there is "probable cause" to believe that they will be uncovered in a particular dwelling.
Unlike the search pursuant to a criminal investigation, the inspection programs at issue here are aimed at securing city-wide compliance with minimum physical standards for private property. The primary governmental interest at stake is to prevent even the unintentional development of conditions which are hazardous to public health and safety. Because fires and epidemics may ravage large urban areas, because unsightly conditions adversely affect the economic values of neighboring structures, numerous courts have upheld the police power of municipalities to impose and enforce such minimum standards even upon existing structures. 11 In determining whether a particular inspection is reasonable - and thus in determining whether there is probable cause to issue a warrant for that inspection - the need for the inspection must be weighed in terms of these reasonable goals of code enforcement.
There is unanimous agreement among those most familiar with this field that the only effective way to seek universal compliance with the minimum standards required by municipal codes is through routine periodic [387 U.S. 523, 536] inspections of all structures. 12 It is here that the probable cause debate is focused, for the agency's decision to conduct an area inspection is unavoidably based on its appraisal of conditions in the area as a whole, not on its knowledge of conditions in each particular building. Appellee contends that, if the probable cause standard urged by appellant is adopted, the area inspection will be eliminated as a means of seeking compliance with code standards and the reasonable goals of code enforcement will be dealt a crushing blow.
In meeting this contention, appellant argues first, that his probable cause standard would not jeopardize area inspection programs because only a minute portion of the population will refuse to consent to such inspections, and second, that individual privacy in any event should be given preference to the public interest in conducting such inspections. The first argument, even if true, is irrelevant to the question whether the area inspection is reasonable within the meaning of the Fourth Amendment. The second argument is in effect an assertion that the area inspection is an unreasonable search. Unfortunately, there can be no ready test for determining reasonableness [387 U.S. 523, 537] other than by balancing the need to search against the invasion which the search entails. But we think that a number of persuasive factors combine to support the reasonableness of area code-enforcement inspections. First, such programs have a long history of judicial and public acceptance. See Frank v. Maryland, 359 U.S., at 367 -371. Second, the public interest demands that all dangerous conditions be prevented or abated, yet it is doubtful that any other canvassing technique would achieve acceptable results. Many such conditions - faulty wiring is an obvious example - are not observable from outside the building and indeed may not be apparent to the inexpert occupant himself. Finally, because the inspections are neither personal in nature nor aimed at the discovery of evidence of crime, they involve a relatively limited invasion of the urban citizen's privacy. Both the majority and the dissent in Frank emphatically supported this conclusion:
The judgment is vacated and the case is remanded for further proceedings not inconsistent with this opinion.

[ Footnote 4 ] In Frank, the Baltimore ordinance required that the health inspector "have cause to suspect that a nuisance exists in any house, cellar or enclosure" before he could demand entry without a warrant, a requirement obviously met in Frank because the inspector observed extreme structural decay and a pile of rodent feces on the appellant's premises. Section 503 of the San Francisco Housing Code has no such "cause" requirement, but neither did the Ohio ordinance at issue in Eaton v. Price, a case which four Justices thought was controlled by Frank. 364 U.S., at 264 , 265, n. 2 (opinion of MR. JUSTICE BRENNAN).

Some cities notify residents in advance, by mail or posted notice, of impending area inspections. State courts upholding these inspections without warrants have imposed a general reasonableness requirement. See cases cited, n. 3, supra.
