OPINION
NIX, Justice.We granted an appeal in this matter from an order of the Superior Court at 242 Pa.Super. 233, 363 A.2d 1246 (1976), affirming a judgment of sentence based upon evidence which appellant contends was obtained as a result of an unlawful search and seizure. The pivotal question is whether appellant had a reasonable expectation of privacy with respect to the contents of certain closed containers stored inside a barn with the consent of the owner’s relative who had a limited right to the use of the barn, where the owner of the barn neither knew nor specifically consented to the storage of such containers. For reasons following, we find that appellant had no reasonable expectation that the contents of the closed boxes and footlockers would not be open to inspection and that the owner of the premises had authority to consent to a search of the closed containers. The order of the Superior Court is hereby affirmed.
In reviewing a suppression court’s findings, this Court will consider the evidence of the Commonwealth and so much of the evidence for the defense as, fairly read in the *302context of the record as a whole, remains uncontradicted. Commonwealth v. Silo, 480 Pa. 15, 18, 389 A.2d 62, 63 (1978), citing Commonwealth v. Harris, 479 Pa. 131, 136, 387 A.2d 869, 872 (1978). The court below summarized the testimony as follows:
“Minnie Bubb was the sole owner of a set of farm buildings which were not used as part of a farming operation. The buildings consisted of a large two-story farmhouse, a woodshed, a shanty, and a large barn, the latter located some 25-30 yards distance from the house. Her niece was married to Robert Hinds, and she rented to Mr. and Mrs. Hinds the one side of the farmhouse for $100 per month, which included utilities. Minnie Bubb resided in the remainder of the farmhouse.
Minnie Bubb never at anytime made any lease, either oral or written, with respect to the barn or any of the out-buildings, but she did from time to time grant permission for relatives to store articles and to utilize lower portions of the barn. Mrs. Hinds kept a horse in the barn prior to her marriage, and, following her marriage, they kept a goat there and parked their car under the barn. Minnie Bubb also gave permission to a brother to store his tractor, lumber, and a lawn mower in the barn, and allowed him to park his truck outside the barn. She never at anytime gave permission to anyone to use the loft, the haymow, or the upper portion of the barn.
Robert Hinds was a friend of the defendant, Bruce Latshaw. Without knowledge, permission or consent of Minnie Bubb, Robert Hinds gave permission to Bruce Latshaw to store and process shipments of marijuana in the hayloft of the barn for $75.00 a shipment. The presence of the defendant and his co-conspirators was explained to Ms. Bubb by informing her that they were college students who were planting a garden and were doing something for a term paper, and that their presence was necessary as a college requirement.
A week before the search and seizure occurred, Minnie Bubb noticed on her brother’s truck, parked outside of the *303barn, greenish material resembling weeds, which she suspicioned [sic.] to be marijuana. She discussed it with her brother and then called in her sister-in-law, Dora Bubb, who climbed into the loft and discovered a brown paper bag which further confirmed their suspicions, and they then called the police to investigate. Not only did Minnie Bubb give permission to the police authorities to search the area, she actually called them and invited them to do so. The police search which followed uncovered 76 pounds of cured marijuana in bags, cartons and footlockers and, in addition thereto, the police discovered dust masks, a 100-lb. hanging scale, a pair of shears, nets for drying marijuana, a pair of binoculars, masking tape, cord and other processing equipment.”
The Fourth Amendment does not preclude a warrantless search of property when consent is given by a person possessing the authority to consent to such search. United States v. Matlock, 415 U.S. 164, 94 S.Ct. 988, 39 L.Ed.2d 242 (1974); Schneckloth v. Bustamonte, 412 U.S. 218, 93 S.Ct. 2041, 36 L.Ed.2d 854 (1973); Bumper v. North Carolina, 391 U.S. 543, 88 S.Ct. 1788, 20 L.Ed.2d 797 (1968); Johnson v. United States, 333 U.S. 10, 68 S.Ct. 367, 92 L.Ed. 436 (1948); Zap v. United States, 328 U.S. 624, 66 S.Ct. 1277, 90 L.Ed. 1477 (1946); Commonwealth v. Kontos, 442 Pa. 343, 276 A.2d 830 (1971); Commonwealth v. Platou, 455 Pa. 258, 312 A.2d 29 (1973); Commonwealth v. Storck, 442 Pa. 197, 275 A.2d 362 (1971). There is no question that Ms. Bubb’s consent was voluntarily given and unlike many situations arising in this area, here the police did not seek the permission to search. Thus, the present case is distinguishable from cases in which the government initiated the search, and cases in which there was an element of governmental coercion in obtaining the alleged consent. See Bumper v. North Carolina, supra; Go-Bart Importing Co. v. United States, 282 U.S. 344, 51 S.Ct. 153, 75 L.Ed. 374 (1931); Amos v. United States, 255 U.S. 313, 41 S.Ct. 266, 65 L.Ed. 654 (1921).
*304At the outset we note that the standing of appellant to contest the validity of the search has been conceded by the appellee. Since the offense charged included as an essential element, the possession of the seized articles at the time of the challenged search, the concession of this point was indeed appropriate. Brown v. United States, 411 U.S. 223, 93 S.Ct. 1565, 36 L.Ed.2d 208 (1973); Commonwealth v. Treftz, 465 Pa. 614, 351 A.2d 265 (1976).
Under the facts of this case, Ms. Bubb’s control of the barn cannot be seriously questioned.1 Nevertheless, appellant argues that since Ms. Bubb’s actual use of the premises was limited and infrequent, she lost the interest which would permit her to give a valid consent for its search. Custody over and control of a building and its contents is not lost merely because the owner has made only infrequent use of the property where the owner has clearly retained the right of access to and use thereof. See United States v. Cook, 530 F.2d 145 (7th Cir. 1976). At all times Ms. Bubb made evident her intention of retaining all of the indicia of ownership. Mr. Hinds’ use of the barn, and that of the other family members, was gratuitous and not pursuant to any type of lease arrangement. Moreover, the permitted uses were not of a general nature but rather explicitly limited. For example, prior to her marriage, Mrs. Hinds was permitted to keep a horse in the barn and after her marriage, she and her husband were allowed to keep a goat and to park their car under the barn. Ms. Bubb allowed her brother to store his tractor, lumber and a lawn mower in the barn. The suppression court found that she did not at any time give permission to anyone to use the loft, the haymow, or the upper portion of the structure. The particularity with which the owner saw fit to grant to others the right to use her property reinforced her control over the property rather than creating an inference of an intention to relinquish that control.
*305The only serious question presented is whether Ms. Bubb’s control over her property vested her with the right to authorize police officials, without a warrant to open and examine the contents of the sealed cartons and locked footlocker that had been placed thereon by another. The answer to this question rests upon a determination as to whether the owner of these containers had a reasonable expectation of privacy as to their contents. The decisions of the United States Supreme Court bearing upon the need to obtain a warrant to authorize a search have been far from consistent, as even the most cursory review makes evident. There has been language which would suggest that the test is not whether the search was reasonable but rather whether it would have been unreasonable to have required the governmental agency to procure a search warrant before making it. See e. g. United States v. U. S. Dist. Ct., 407 U.S. 297, 92 S.Ct. 2125, 32 L.Ed.2d 752 (1972); Chimel v. Calif., 395 U.S. 752, 89 S.Ct. 2034, 23 L.Ed.2d 685 (1969). However, the prevailing opinions in South Dakota v. Opperman, 428 U.S. 364, 96 S.Ct. 3092, 49 L.Ed.2d 1000 (1976) appear to focus upon the reasonableness of the search. Furthermore, it has been indicated that a warrantless search is per se unreasonable under the Fourth Amendment. Cady v. Dombrowski, 413 U.S. 433, 93 S.Ct. 2523, 37 L.E.2d 706 (1973); Katz v. United States, 389 U.S. 347, 88 S.Ct. 507, 19 L.Ed.2d 576 (1967).2 However, exceptions under the umbrella of exigent circumstances have been well established.3
*306In any event the third party consent exception to the warrant requirement is firmly established. South Dakota v. Opperman, supra; U. S. v. Matlock, supra; Schneckloth v. Bustamonte, supra; Frazier v. Cupp, 394 U.S. 731, 89 S.Ct. 1420, 22 L.Ed.2d 684 (1969). The basis for the principle that the consent of one who possesses common authority over premises or effects is valid as against the absent, non-consenting person with whom that authority is shared, is discussed at length in United States v. Matlock, supra. In Matlock, the Court focused upon the joint access or control, “so that it is reasonable to recognize that any of the co-inhabitants has the right to permit the inspection in his own right and that the others assume the risk that one of their number might permit the common area to be searched.” Id. 415 U.S. at 171, n.7, 94 S.Ct. at 993.
A close reading of the above quoted language from Mat-lock indicates that the test is not based merely on appellant’s subjective expectation of privacy, but rests also on a finding that said expectation was reasonable. In determining what is “reasonable” all the surrounding facts and circumstances must be considered.4 Here, appellant’s purported expecta*307tion of privacy is greatly limited by the legitimate interest of Minnie Bubb in the subject property. Accordingly, what distinguishes the present case from other cases which concern the issue of the ability of a third party to consent to a search of the property or effects of another party is the utter lack of any consensual relationship between Ms. Bubb and the appellant, coupled with the inescapable fact that Ms. Bubb at no time surrendered any indicia of her absolute control over the barn. Relinquishment of this control cannot be implied from mere sporadic permission granted by Ms. Bubb to her tenant and various others for specific uses. As the undisputed owner of the barn, Ms. Bubb had the unimpeded ability to act at will with regard to the contents of the barn. Absent any express or implied consensual understanding with Ms. Bubb, the appellant had no expectation of privacy with regard to the boxes or their contents placed therein. Ms. Bubb’s rights thus were superior to the appellant’s rights in the barn and its contents. Appellant could not force Ms. Bubb to permit the property to remain in the barn, nor could he impose upon her any custodial duty to protect or otherwise harbor the property.
The record does not reflect what representations Mr. Hinds might have made with reference to his control over the barn.
Nevertheless, while these statements may have been such as to provide a basis for a reasonable subjective expectation of privacy, based upon the facts as they actually existed, the expectation could not be deemed to have been reasonable. The right of an owner of property to request the police to open and examine closed containers upon finding the objects upon her property, which were placed there without her knowledge or consent, particularly where she had reason to believe that they might contain contra*308band,5 is indisputable. The fact that Hinds’ statements may have been misleading does not vest a constitutional protection in a situation where it obviously would not otherwise exist. The independent right of Ms. Bubb to authorize the search of her property and all items thereon could under no theory have been affected by any representations made by Mr. Hinds to appellant. We therefore hold that the instant search did not violate appellant’s right to be free from unreasonable search and seizure.
Order of the Superior Court is affirmed.
POMEROY, J., concurred in the result. ROBERTS, J., filed a dissenting opinion in which O’BRIEN and MANDERINO, JJ., joined. MANDERINO, J., filed a dissenting opinion.. The dissenters in the Superior Court readily admitted Ms. Bubb’s right to authorize a search of the barn. Commonwealth v. Latshaw, 242 Pa.Super. 233, 237, 363 A.2d 1246, 1248 (1976).
. Recently, in the decision in Mincy v. Ariz., 437 U.S. 385, 98 S.Ct. 2408, 57 L.Ed.2d 290 (decided June 21, 1978), the United States Supreme Court reaffirmed the Katz view that warrantless searches are per se unreasonable, “subject only to a few specifically established and well-delineated exceptions.” Id. at 390, 98 S.Ct. at 2412.
. “Exigent circumstances” is a generic term encompassing numerous examples where it would be unreasonable to require law enforcement agencies to obtain a search warrant prior to effecting a search. Thus, warrants have not been required under the following circumstances: a search incident to a lawful arrest, United States v. Rabinowitz, 339 U.S. 56, 70 S.Ct. 430, 94 L.Ed. 653 (1950); hot pursuit of a fleeing felon, Warden v. Hayden, 387 U.S. 294, 87 S.Ct. 1642, 18 L.Ed.2d 782 (1967); emergency requiring the need for immediate action to prevent destruction of evidence, Schmerber v. California, *306384 U.S. 757, 86 S.Ct. 1826, 16 L.Ed.2d 908 (1966); and emergency requiring the need for immediate action to prevent evidence, which is easily moveable, from being quickly removed from the jurisdiction, Carroll v. United States, 267 U.S. 132, 45 S.Ct. 280, 69 L.Ed. 543 (1925).
. See South Dakota v. Opperman, 428 U.S. 364, 375, 96 S.Ct. 3092, 49 L.Ed.2d 1000 (1976). The most familiar expression of a reasonable expectation of privacy, i. e., one which is entitled to protection under the Fourth Amendment, is the test suggested by Mr. Justice Harlan. See Katz v. United States, 389 U.S. 347, 360, 88 S.Ct. 507, 19 L.Ed.2d 576 (1967) (Harlan, J., concurring):
“As the Court’s opinion states, ‘the Fourth Amendment protects people, not places.’ The question, however, is what protection it affords to those people. Generally, as here, the answer to that question requires reference to a ‘place.’ My understanding of the rule that has emerged from prior decisions is that there is a two-fold requirement, first that a person have exhibited an actual (subjective) expectation of privacy and, second, that the expectation be one that society is prepared to recognize as ‘reasonable.’ Thus a man’s home is, for most purposes, a place where he expects privacy, but objects, activities, or statements that he exposes to the ‘plain view’ of outsiders are not ‘protected’ because no intention to *307keep them to himself has been exhibited. On the other hand, conversations in the open would not be protected against being overheard, for the expectation of privacy under the circumstances would be unreasonable.” Id. at 361, 88 S.Ct. at 516.
. There have been several circuit court decisions suggesting that a search authorized by a third party, who has a legitimate interest in exculpating himself or herself from possible criminal involvement with the suspected contraband, is not an unreasonable search under the Fourth Amendment. See United States v. Diggs, 544 F.2d 116 (3rd Cir. 1976); United States v. Botsch, 364 F.2d 542 (2nd Cir. 1966). This theory would also justify the result we reach today.
