As a result of three warrantless inspections of a private social club by Boston police officers, the defendants were both charged with eight criminal complaints.2 The defendants’ motion to suppress was denied as to evidence obtained as a result of a warrantless inspection conducted *655on March 1, 1981, but allowed as to evidence obtained as a result of warrantless inspections made on March 8 and March 15. The Commonwealth has appealed from the judge’s order as to the latter inspections. See Mass.R.Crim. P. 15(a)(2), 378 Mass. 882-883 (1979). The Commonwealth contends that the evidence ordered suppressed by the judge was obtained in the course of three warrantless administrative inspections authorized by G. L. c. 140, § 201.3 The Commonwealth does not argue that the inspections on March 8 or 15 were permissible in the absence of statutory authority.4 The judge ruled that the statute does not authorize the type of inspection that was conducted here.
We summarize the motion judge’s findings of fact. The defendants are the managers of The Loft Twenty One Association, Inc. (Loft), a private social club located on the second floor of a building on Stanhope Street, Boston. The defendants claim the third floor as their residence.5 During *656the relevant period of time in March, 1981, the Loft held a “club victualler” license issued by the city of Boston, in accordance with G. L. c. 140, § 21E.6 The premises covered by the license were the second floor. At that time, the Loft provided a place for its members and their guests to socialize on weekend nights, including the early morning hours after other social establishments were closed. When the Loft was open, members and their guests gained entrance by “checking in” at the second floor landing with the defendant D’Onofrio, who positioned himself there each night for the purpose of monitoring a sign-in sheet and, with respect to some patrons, collecting an admission fee.
On Sunday, March 8, 1981, at approximately 4:00 a.m., five police officers entered the Loft for the purpose of making a warrantless inspection. D’Onofrio asked to be shown a search warrant, his request was ignored, and the officers conducted a search of the second floor over D’Onofrio’s objection. They observed persons dancing, seized a glass that contained an alcoholic beverage, and informed the defendants that complaints would be filed. The third floor was not searched.
In the early morning hours of Sunday, March 15, six police officers conducted another warrantless inspection. Over D’Onofrio’s objection, the officers inspected the second floor. On this occasion, however, they also entered and inspected the third floor, again over objection. On that floor, they observed a large number of persons dancing and, in one corner of the room, several partially clothed men engaged in group sexual activity. The officers ordered the activity to cease, and subsequently informed the defendants that further complaints would be filed against them for permitting sexual activity to take place in the Loft. Subsequently, criminal complaints issued against the defendants. We affirm the judge’s order allowing the defendants’ sup*657pression motion as to the warrantless inspections conducted on March 8 and 15.
The United States Supreme Court has extended the warrant requirement of the Fourth Amendment to administrative searches of private and commercial premises. See v. Seattle, 387 U.S. 541, 543 (1967). Marshall v. Barlow’s Inc., 436 U.S. 307, 311-312 (1978). Therefore, unless some recognized exception to the warrant requirement applies, a warrant is required to conduct an administrative inspection. Marshall v. Barlow’s Inc., supra at 313. The United States Supreme Court has recognized exceptions from the search warrant requirement for “pervasively regulated business[es],” United States v. Biswell, 406 U.S. 311, 316 (1972) (firearms), 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) (liquor). Inspections of such businesses or industries “may proceed without a warrant where specifically authorized by statute.” United States v. Biswell, 406 U.S. at 317. Also see Commonwealth v. Lipomi, 385 Mass. 370, 380 (1982), where the court, quoting from Donovan v. Dewey, 432 U.S. 594, 600 (1981), stated that it is “clear that a warrant may not be constitutionally required when [the Legislature] has reasonably determined that warrantless searches are necessary to further a regulatory scheme and the [governmental] regulatory presence is sufficiently comprehensive and defined that the owner of commercial property cannot help but be aware that his property will be subject to periodic inspections undertaken for specific purposes.” Three factors must be present in order to have a lawful warrantless administrative search. They are (1) the enterprise sought to be inspected must be engaged in a pervasively regulated business, (2) the warrantless inspection must be a crucial part of a regulatory scheme designed to further an urgent governmental interest, (3) the inspection must be conducted in accord with a procedure authorized by statute itself carefully limited as to time, place, and scope. Commonwealth v. Lipomi, 385 Mass. at 380.
*658The Loft’s license authorized it “to dispense food and beverages to be consumed on its premises, to its stockholders or members and their guests, but to no other.” The judge ruled that by virtue of G. L. c. 140, § 201, the Legislature had placed the food and beverage industry within the perimeters of the Colonnade-Biswell warrant exception. Assuming without deciding that the judge was correct in so holding,7 the statute does not authorize forcible nonconsensual inspections of the type conducted at the Loft. The statute provides that a fine may be imposed on the person obstructing or hindering such inspection. There is nothing in the statute that authorizes forcible entries. In examining a warrantless search made under a similar statutory provision, the United States Supreme Court stated, “Under the existing statutes, Congress selected a standard that does not include forcible entries without a warrant. It resolved the issue, not by authorizing forcible, warrantless entries, but by making it an offense for a licensee to refuse admission to the inspector.” Colonnade Catering Corp. v. United States, 397 U.S. at 77.8 Commonwealth v. Lipomi, supra at 378. Because Congress had not authorized forcible entries as a part of the inspection procedure, the Court held that the evidence seized should be suppressed. Colonnade Catering Corp. v. United States, supra at 77. We follow *659the rationale of Colonnade and conclude that the Legislature, in providing that a fine be levied against anyone who refuses to permit an official inspection of licensed premises, precludes the type of warrantless nonconsensual inspections undertaken by the police here. Because of our holding, we do not consider the defendant’s argument that G. L. c. 140, § 201, is unconstitutional under the factors cited in Commonwealth v. Lipomi, 385 Mass. at 380. See School Comm. of Greenfield v. Greenfield Educ. Assn., 385 Mass. 70, 79 (1982) (“It is our duty to construe statutes so as to avoid . . . constitutional difficulties, if reasonable principles of interpretation permit it”).
Order allowing motion to suppress affirmed.
