MR. JUSTICE WHITE delivered the opinion of the Court.
Section 8 (a) of the Occupational Safety and Health Act of 1970 (OSHA or Act)*fn1 empowers agents of the Secretary of Labor (Secretary) to search the work area of any employment facility within the Act's jurisdiction. The purpose of the search is to inspect for safety hazards and violations of OSHA regulations. No search warrant or other process is expressly required under the Act.
On the morning of September 11, 1975, an OSHA inspector entered the customer service area of Barlow's, Inc., an electrical and plumbing installation business located in Pocatello, Idaho. The president and general manager, Ferrol G. "Bill" Barlow, was on hand; and the OSHA inspector, after showing his credentials,*fn2 informed Mr. Barlow that he wished to conduct
a search of the working areas of the business. Mr. Barlow inquired whether any complaint had been received about his company. The inspector answered no, but that Barlow's, Inc., had simply turned up in the agency's selection process. The inspector again asked to enter the nonpublic area of the business; Mr. Barlow's response was to inquire whether the inspector had a search warrant. The inspector had none. Thereupon, Mr. Barlow refused the inspector admission to the employee area of his business. He said he was relying on his rights as guaranteed by the Fourth Amendment of the United States Constitution.
Three months later, the Secretary petitioned the United States District Court for the District of Idaho to issue an order compelling Mr. Barlow to admit the inspector.*fn3 The requested order was issued on December 30, 1975, and was presented to Mr. Barlow on January 5, 1976. Mr. Barlow again refused admission, and he sought his own injunctive relief against the warrantless searches assertedly permitted by OSHA. A three-judge court was convened. On December 30, 1976, it ruled in Mr. Barlow's favor. 424 F.Supp. 437. Concluding that Camara v. Municipal Court, 387 U.S. 523, 528-529 (1967), and See v. Seattle, 387 U.S. 541, 543 (1967), controlled this case, the court held that the Fourth Amendment required a warrant for the type of search involved here*fn4 and that the statutory authorization for warrantless inspections was unconstitutional. An injunction against searches or inspections pursuant to § 8 (a) was entered. The Secretary appealed, challenging the judgment, and we noted probable jurisdiction. 430 U.S. 964.
The Secretary urges that warrantless inspections to enforce OSHA are reasonable within the meaning of the Fourth Amendment. Among other things, he relies on § 8 (a) of the Act, 29 U. S. C. § 657 (a), which authorizes inspection of business premises without a warrant and which the Secretary urges represents a congressional construction of the Fourth Amendment that the courts should not reject. Regrettably, we are unable to agree.
The Warrant Clause of the Fourth Amendment protects commercial buildings as well as private homes. To hold otherwise would belie the origin of that Amendment, and the American colonial experience. An important forerunner of the first 10 Amendments to the United States Constitution, the Virginia Bill of Rights, specifically opposed "general warrants, whereby an officer or messenger may be commanded to search suspected places without evidence of a fact committed."*fn5 The general warrant was a recurring point of contention in the Colonies immediately preceding the Revolution.*fn6 The particular offensiveness it engendered was acutely felt by the merchants and businessmen whose premises and products were inspected for compliance with the several parliamentary revenue measures that most irritated the colonists.*fn7 "[The] Fourth Amendment's commands grew in large measure out of the colonists' experience with the writs of assistance . . . [that] granted sweeping power to customs officials and other agents of the King to search at large for smuggled goods." United States v. Chadwick, 433 U.S. 1, 7-8 (1977).
See also G. M. Leasing Corp. v. United States, 429 U.S. 338, 355 (1977). Against this background, it is untenable that the ban on warrantless searches was not intended to shield places of business as well as of residence.
This Court has already held that warrantless searches are generally unreasonable, and that this rule applies to commercial premises as well as homes. In Camara v. Municipal Court, supra, at 528-529, we held:
"[Except] in certain carefully defined classes of cases, a search of private property without proper consent is 'unreasonable' unless it has been authorized by a valid search warrant."
On the same day, we also ruled:
"As we explained in Camara, a search of private houses is presumptively unreasonable if conducted without a warrant. The businessman, like the occupant of a residence, has a constitutional right to go about his business free from unreasonable official entries upon his private commercial property. The businessman, too, has that right placed in jeopardy if the decision to enter and inspect for violation of regulatory laws can be made and enforced by the inspector in the field without official authority evidenced by a warrant." See v. Seattle, supra, at 543.
These same cases also held that the Fourth Amendment prohibition against unreasonable searches protects against warrantless intrusions during civil as well as criminal investigations. Ibid. The reason is found in the "basic purpose of this Amendment . . . [which] is to safeguard the privacy and security of individuals against arbitrary invasions by governmental officials." Camara, supra, at 528. If the government intrudes on a person's property, the privacy interest suffers whether the government's motivation is to investigate violations of criminal laws or breaches of other statutory or
regulatory standards. It therefore appears that unless some recognized exception to the warrant requirement applies, See v. Seattle would require a warrant to conduct the inspection sought in this case.
The Secretary urges that an exception from the search warrant requirement has been recognized for "pervasively regulated [businesses]," United States v. Biswell, 406 U.S. 311, 316 (1972), and for "closely regulated" industries "long subject to close supervision and inspection." Colonnade Catering Corp. v. United States, 397 U.S. 72, 74, 77 (1970). These cases are indeed exceptions, but they represent responses to relatively unique circumstances. Certain industries have such a history of government oversight that no reasonable expectation of privacy, see Katz v. United States, 389 U.S. 347, 351-352 (1967), could exist for a proprietor over the stock of such an enterprise. Liquor (Colonnade) and firearms (Biswell) are industries of this type; when an entrepreneur embarks upon such a business, he has voluntarily chosen to subject himself to a full arsenal of governmental regulation.
Industries such as these fall within the "certain carefully defined classes of cases," referenced in Camara, 387 U.S., at 528. The element that distinguishes these enterprises from ordinary businesses is a long tradition of close government supervision, of which any person who chooses to enter such a business must already be aware. "A central difference between those cases [ Colonnade and Biswell ] and this one is that businessmen engaged in such federally licensed and regulated enterprises accept the burdens as well as the benefits of their trade, whereas the petitioner here was not engaged in any regulated or licensed business. The businessman in a regulated industry in effect consents to the restrictions placed upon him." Almeida-Sanchez v. United States, 413 U.S. 266, 271 (1973).
The clear import of our cases is that the closely regulated industry of the type involved in Colonnade and Biswell is the exception. The Secretary would make it the rule. Invoking
the Walsh-Healey Act of 1936, 41 U. S. C. § 35 et seq., the Secretary attempts to support a conclusion that all businesses involved in interstate commerce have long been subjected to close supervision of employee safety and health conditions. But the degree of federal involvement in employee working circumstances has never been of the order of specificity and pervasiveness that OSHA mandates. It is quite unconvincing to argue that the imposition of minimum wages and maximum hours on employers who contracted with the Government under the Walsh-Healey Act prepared the entirety of American interstate commerce for regulation of working conditions to the minutest detail. Nor can any but the most fictional sense of voluntary consent to later searches be found in the single fact that one conducts a business affecting interstate commerce; under current practice and law, few businesses can be conducted without having some effect on interstate commerce.
The Secretary also attempts to derive support for a Colonnade-Biswell -type exception by drawing analogies from the field of labor law. In Republic Aviation Corp. v. NLRB, 324 U.S. 793 (1945), this Court upheld the rights of employees to solicit for a union during non-working time where efficiency was not compromised. By opening up his property to employees, the employer had yielded so much of his private property rights as to allow those employees to exercise § 7 rights under the National Labor Relations Act. But this Court also held that the private property rights of an owner prevailed over the intrusion of non-employee organizers, even in non-working areas of the plant and during non-working hours. NLRB v. Babcock & Wilcox Co., 351 U.S. 105 (1956).
The critical fact in this case is that entry over Mr. Barlow's objection is being sought by a Government agent.*fn8 Employees
are not being prohibited from reporting OSHA violations. What they observe in their daily functions is undoubtedly beyond the employer's reasonable expectation of privacy. The Government inspector, however, is not an employee. Without a warrant he stands in no better position than a member of the public. What is observable by the public is observable, without a warrant, by the Government inspector as well.*fn9 The owner of a business has not, by the necessary utilization of employees in his operation, thrown open the areas where employees alone are permitted to the warrantless scrutiny of Government agents. That an employee is free to report, and the Government is free to use, any evidence of noncompliance with OSHA that the employee observes furnishes no justification for federal agents to enter a place of business from which the public is restricted and to conduct their own warrantless search.*fn10
The Secretary nevertheless stoutly argues that the enforcement scheme of the Act requires warrantless searches, and that the restrictions on search discretion contained in the Act and its regulations already protect as much privacy as a warrant would. The Secretary thereby asserts the actual reasonableness of OSHA searches, whatever the general rule against warrantless searches might be. Because "reasonableness is still the ultimate standard," Camara v. Municipal Page 316} Court, 387 U.S., at 539, the Secretary suggests that the Court decide whether a warrant is needed by arriving at a sensible balance between the administrative necessities of OSHA inspections and the incremental protection of privacy of business owners a warrant would afford. He suggests that only a decision exempting OSHA inspections from the Warrant Clause would give "full recognition to the competing public and private interests here at stake." Ibid.
The Secretary submits that warrantless inspections are essential to the proper enforcement of OSHA because they afford the opportunity to inspect without prior notice and hence to preserve the advantages of surprise. While the dangerous conditions outlawed by the Act include structural defects that cannot be quickly hidden or remedied, the Act also regulates a myriad of safety details that may be amenable to speedy alteration or disguise. The risk is that during the interval between an inspector's initial request to search a plant and his procuring a warrant following the owner's refusal of permission, violations of this latter type could be corrected and thus escape the inspector's notice. To the suggestion that warrants may be issued ex parte and executed without delay and without prior notice, thereby preserving the element of surprise, the Secretary expresses concern for the administrative strain that would be experienced by the inspection system, and by the courts, should ex parte warrants issued in advance become standard practice.
We are unconvinced, however, that requiring warrants to inspect will impose serious burdens on the inspection system or the courts, will prevent inspections necessary to enforce the statute, or will make them less effective. In the first place, the great majority of businessmen can be expected in normal course to consent to inspection without warrant; the Secretary has not brought to this ...
