In this сase, in which defendant Will Nelson Clark stands indicted in the United States District Court for the Western District of New York (William M. Skretny,
Judge)
on two counts of unlawful possession of cocaine base, the United States appeals from a pre-trial order entered on July 16, 2009, suppressing both physical evidence seized pursuant to a search warrant and defendant’s post-arrest statement on the grounds that (1) the warrant to search a multi-family dwelling was not supported by probable cause; (2) defendant’s statements were tainted by the unlawful search; and (3) the “good faith exception” to the exclusionary rule announced in
United States v. Leon,
I. Background
A. The Challenged Search Warrant
On June 10, 2008, detectives with the Niagara Falls Police Department sought and obtained from a city court judge a warrant to search both “the person known as WILL N. CLARK,” and the premises at “1015 Fairfield Ave, being a multi family dwelling” for “[cjocaine and any other controlled substances” as well as a range of physical items indicative of drug dealing. Search Warrant at 1. Although nothing before the issuing judge appears to have indicated the size of the building and whether “multi family” referenced two or twenty distinct residential units, the warrant authorized a search of the entire premises, including “any and all persons present at this location during execution of said search warrant, all rooms, contents of those rooms, including any computers and hard drives of same ..., hallways, stairways, storage areas, basement, attic areas, closets, any and all locked and secured areas, locked safes or containers and porches to said address.” Id. 1
In support of this expansive warrant, two detectives swore to an affidavit disclosing that an informant of “unknown reliability” 2 had advised police that Clark was selling cocaine at 1015 Fairfield Avenue, a “multi family dwelling,” but only to persons previously known to him. Aff. for Search Warrant (“Warrant Aff.”) at 2-3. The informant had also stated that Clark had “full control over 1015 Fairfield Ave.” Id. at 2. In further support of the warrant, the detectives swore that in the course of numerous surveillances of the subject premises, police had observed defendant Clark “entering and remaining and exercising control at the residence of 1015 Fairfield Ave.” Id. In addition, in May 2008, police supervised two controlled purchases of cocaine by the confidential informant from Clark. On the first occasion, after confirming that the informant *92 had no drugs in his possession, police observed him “going directly to the area of 1015 Fairfield Ave, staying for a short period of time, and then retu[r]ning directly back to your deponents” whereupon the informant turned over an “off white chunk substance” that tested as cocaine. Id. On the second occasion, after again confirming that the informant had no drugs in his possession, police observed him “going directly to the area of 1015 Fairfield Ave, entering the front porch area, staying for a short period of time, and then returning directly back to your deponents,” where he turned over an “off white chunk substance” that tested as cocaine. Id.
B. The Evidence and Statements Obtained During Execution of the Search Warrant
Police executed the challenged search warrant on June 12, 2008, at which time Clark was present in a downstairs apartment on the 1015 Fairfield Avenue premises. From that apartment, police seized a quantity of drugs, which subsequently tested as cocaine base, approximately $1703 in cash, and various items of drug paraphernalia. 3 Clark was promptly arrested and advised of his Miranda rights, whereupon he was shown the seized contraband and asked if it was real. Clark nodded affirmatively and asked, “What am I looking at? 25 or what?” Appellee’s Br. at 5.
C. District Court Proceedings
On July 31, 2008, a federal grand jury in the Western District of New York indicted Clark on two counts of drug possession; Count One charges that on June 12, 2008, Clark possessed with intent to distribute 50 grams or more of cocaine base in violation of 21 U.S.C. § 841(a)(1), (b)(1)(A); Count Two charges Clark with simple possession of more than 5 grams of cocaine base on the same date in violation of 21 U.S.C. § 844(a).
Clark filed a pre-trial motion to suppress the physical evidence seized on June 12, 2008, arguing that it derived from a warrant that was invalid for lack of probable cause, overbreadth, and staleness. He moved to suppress his post-arrest query, arguing that it was tainted by the unlawful search. 4
Pursuant to a general referral of all pretrial matters, Magistrate Judge Jeremiah H. McCarthy issued reports on April 14 and 27, 2009, recommending that the district court suppress both the seized evidence and the post-arrest statement. See Report & Recommendation, United States v. Clark, No. 08-CR-196(S)(M) (W.D.N.Y. Apr. 27, 2009); Interim Report and Recommendation (“Interim R & R”) at 2, *93 United States v. Clark, 08-CR-196(S)(M) (W.D.N.Y. Apr. 14, 2009). The magistrate judge concluded that the warrant was not supported by probable cause to search the whole of the subject multi-family dwelling and that the unlawful search tainted Clark’s post-arrest statement. The magistrate judge further concluded that the government could not claim the benefits of the good faith exception to the exclusionary rule because (1) the issuing judge had failed to act as a neutral and detached magistrate, (2) the warrant was facially defective, and (3) the lack of probable cause to search the entire multi-family dwelling was so apparent that police could not reasonably rely on the validity of the warrant. Accordingly, the magistrate judge recommended that the district court suppress the seized physical evidence as the product of an unreasonable search and Clark’s post-arrest statement because it was tainted by the search.
After unsuccessfully seeking reconsideration, the government filed objections to the magistrate judge’s reports with the district court, which rejected them without discussion in a text order and granted defendant’s suppression motion. The government timely appеaled, invoking our jurisdiction pursuant to 18 U.S.C. § 3731.
II. Discussion
A. Standard of Review
The government submits that the district court erred in ordering suppression of seized evidence and Clark’s statements because the challenged search warrant was supported by probable cause and, in any event, Leon’s good faith exception to the exclusionary rule applies to this case. 5
In considering these arguments, we are mindful that a court reviewing a challenged warrant — whether at the district or appellate level — “must accord considerable deference to the probable cause determination of the issuing magistrate.”
Walczyk v. Rio,
When, as in this case, we review a district court’s assessment of a search conducted pursuant to a warrant, we apply the clear error standard to its findings of historical fact, but we “analyze
de novo
the ultimate determination of such legal issues as probable cause and the good faith of police officials in relying upon a warrant.”
United States v. Smith,
Applying these principles to this case, we conclude that, even after deferential review, we cannot identify a “substantial basis” for the issuing judge to have author *94 ized a search of the entire multi-family dwelling at 1015 Fairfield Avenue and all persons in it. At the same time, however, we conclude that defendant’s suppression motion should have been denied pursuant to the good faith exception to the exclusionary rule. The record does not support the district court’s conclusions that the issuing judge abandoned his neutral and detached role, that the warrant was invalid on its face, or that the lack of probable cause in the warrant affidavit was so evident that executing officers could not reasonably have relied on the validity of the issued warrant.
B. The Lack of Probable Cause to Search the Subject Multi-Family Dwelling
1. Identifying Probable Cause to Search Multiple-Occupancy Premises
To protect against unreasonable searches and seizures, the Fourth Amendment states that “no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.” U.S. Const, amend. IV. As has long been recognized, probable cause is “a fluid concept — turning on the assessment of probabilities in particular factual contexts — not readily, or even usefully, reduced to a neat set of legal rulеs.”
Illinois v. Gates,
Particularity concerns frequently arise in circumstances where the description in the warrant of the place to be searched is so vague that it fails reasonably to alert executing officers to the limits of their search authority,
see generally Stanford v. Texas,
2. “Control” as a Factor Relevant to Probable Cause
The government acknowledges this body of law, but submits that it is subject to an exception: “Probable cause need not be shown for each particular unit [of a multiple-occupancy building] when the application establishes that the suspect exercises control over the entire premises.” Appellant’s Br. at 13 (emphasis added). We do not think the law supports such an absolute pronouncement.
The New York Court of Appeals, whose rulings presumably controlled issuance of the warrant here at issue, as well as several of our sister circuits, have referenced “control” of a multiple-occupancy building as a fact that can support a warrant to search the whole premises.
See People v. Tambe,
Control, after all, can be manifested in various ways — e.g., ownership, occupancy, access, authority to exclude others — and exercised to varying degrees. Thus, even though a person may own the multiple-occupancy building from which he deals drugs, probable cause to search the whole *96 is more likely to be identified if the building is a two-family structure of which the suspect is the only occupant than if it is a twenty-family structure in which the suspect occupies only a single residential unit with other units leased by families unassociated with his criminality. We do not attempt to hypothesize all the contexts in which various types or degrees of cоntrol might be evidenced in a multiple-occupancy building. We note simply that they are sufficiently numerous to defeat the government’s argument that a simple allegation of control — necessarily and by itself — provides a substantial basis for authorizing the challenged search of a multiple-occupancy building.
Indeed, we observe that the single case cited by the government in support of its control argument,
United States v. Gusan,
This is consistent with an exception that has been summarized as follows:
[I]f the building in question from its outward appearance would be taken to be a single-occupancy structure and neither the affiant nor other investigating officers nor the executing officers knew or had reason to know of the structure’s actual multiple-occupancy character until execution of the warrant was under way, then the warrant is not defective for failure to specify a subunit within the named building.

supra,
§ 4.5(b), at 581-82
&
n. 64 (collecting cases recognizing exception (footnote omitted));
see Maryland v. Garrison,
3. The Affidavit’s Allegations of Control Were Insufficient To Establish Probable Cause To Search the Entire Subject Premises
When the allegations of “control” in this case are properly considered in the
*97
context of the totality of circumstances, we conclude that the whole does not establish probable cause to support the challenged search of all residеnces in the subject building. To be sure, an informant reported that Clark exercised “full control” over the building, but the informant was then untried and his assertion entirely conelusory. While no specific test determines when informant information can be relied on in making a probable cause determination, the Supreme Court has instructed that the “totality of circumstances” must present the magistrate with “[sjufficient information ... to allow
that official
” to make the necessary determinations; “his action cannot be a mere ratification of the bare conclusions of others.”
Illinois v. Gates,
Here, such information was totally lacking on the issue of control.
8
First, the issuing judge was not advised as to the size of the building or the number of residential units it contained, which would have provided an important, if not essential, context for evaluating the probability of the “full control” allegation. Second, nothing in the warrant affidavit advised the issuing judge what the informant meant by “full control.” Indeed, the affidavit did not even disclose whether the informant’s allegation was based on personal observation, a hearsay account, or mere rumor. Third, the affidavit did not provide any descriptive facts consistent with the full control allegation. We do not suggest that any one of these facts was necessary to establish probable cause,
see id.
at 230,
In urging otherwise, the government submits that the informant’s control conclusion must be considered together with two other allegations: (1) that surveillance officers observed Clark “entering and remaining and exercising control at the residence of 1015 Fairfield Ave,” Warrant Aff. at 2 (emphasis added), and (2) that the informant made two controlled purchases of cocaine from Clark at the subject building. We are not persuaded that the sum of these allegations provided a substantial basis to order the search of all parts of and persons in the multi-family dwelling.
Focusing first on the controlled purchase allegations, the warrant affidavit states only that the informant went to the “area” of 1015 Fairfield Avenue to make the first purchase and to the building’s “front porch area” to make the second. Id. at 3. Thus, these allegations failed to provide any information as to where within the multi-family dwelling Clark dealt or stored drugs, much less did they establish his control over all units in and parts of the premises. 9 The government does not *98 contend otherwise. Rather, it submits that the controlled purchases corroborated the informant’s allegation that Clark was dealing drugs at 1015 Fairfield Avenue and that the partial corroboration provided a basis for the issuing judge to credit the informant’s further allegation that Clark exercised “full control” over the building.
Partial corroboration of an informant is a circumstance that, on totality review, may allow a judicial officer to credit the informant’s whole account.
See Illinois v. Gates,
The law to which we refer is, of course, the Fourth Amendment, which specifically identifies the right of persons to be secure in their homes as a basis for conditioning the issuance of warrants on a demonstration of probable cause and particularity.
See generally Georgia v. Randolph,
This conclusion is consistent with the viеw of the New York Court of Appeals in
People v. Tambe,
*99 Nor do we think that “more” was supplied by surveillance observations of Clark “entering and remaining and exercising control at the residence at 1015 Fairfield Ave.” Warrant Aff. at 2 (emphasis added). While the surveillance allegation derived from police officers rather than an untested informant, and was based on personal observation, it was nevertheless conclusory. The issuing judge was not told what the officers meant by “exercising control,” a concept that could easily mean less than full control. A surveillance officer who saw a suspect unlock the common entry door to a multiple-occupancy building might reasonably think he was “exercising control” over the building, but that would hardly provide a substantial basis for finding probable cause to search an unspecified number of residential units not linked to the defendant or his criminal activities. We further note that to the extent the affidavit reported that surveillance observed Clark exercising control “at the residence,” the affidavit is devoid of information that would allow the issuing judge to determine whether “residence” referred to the building as a whole or to a particular residential unit.
In sum, while the totality of circumstances permitted the issuing judge to find it probable that Clark was dealing drugs from somewhere within 1015 Fairfield Avenue, it did not provide a substantial basis to conclude that Clark so controlled the various residential units in that multi-family dwelling that there was probable cause to think evidence of his criminal conduct could be found throughout the building. 10
C. The Good Faith Exception Applies to this Case
A determination that the warrant at issue was not supported by probable cause to search the entire multi-family dwelling does not automatically dictate the suppression of all physical evidence seized or statements derived therefrom. As the Supreme Court recently reminded courts, suppression is “‘our last resort, not our first impulse’ ” in dealing with violations of the Fourth Amendment.
Herring v. United States,
“The burden is on the government to demonstrate the objective reasonableness of the officers’ good faith reliance” on an invalidated warrant.
United States v. George,
“[S]еarehes pursuant to a warrant will rarely require any deep inquiry into reasonableness,” Illinois v. Gates,462 U.S. at 267 [103 S.Ct. 2317 ] (White, J., concurring in judgment), for “a warrant issued by a magistrate normally suffices to establish” that a law enforcement officer has “acted in good faith in conducting the search.” United States v. Ross,456 U.S. 798 , 823 n. 32 [102 S.Ct. 2157 ,72 L.Ed.2d 572 ] (1982).
United States v. Leon,
(1) where the issuing magistrate has been knowingly misled; (2) where the issuing magistrate wholly abandoned his or her judicial role; (3) where the application is so lacking in indicia of probable cause as to render reliance upon it unreasonable; and (4) where the warrant is so facially deficient that reliance upon it is unreasonable.
United States v. Moore,
Here, the district court concluded that the last three circumstances were all present in this case, precluding application of the good faith exception. Reviewing this determination de novo, we conclude to the contrary.
1. The Issuing Magistrate Did Not Abandon His Judicial Role
The district court concluded thаt the issuing judge had abandoned his judicial role by relying solely on the affidavit’s conclusory allegations of control in finding probable cause to search the whole of a multiple-occupancy building. This misconstrues the abandonment concern identified in Leon.
There, the Supreme Court observed that in issuing warrants, a magistrate must “perform his neutral and detached function” as a judicial officer “and not serve merely as a rubber stamp for the police.”
United States v. Leon,
In
Lo-Ji Sales,
a town justice issued a warrant for the seizure of obscene materials from an adult bookstore. The justice then accompanied police officers and prosecutors to thе store and, in the course of a six-hour search, reviewed items for himself and decided which could be seized.
See Lo-Ji Sales, Inc. v. New York,
Animating these two decisions is a common precept: that “someone independent of the police and prosecution must dеtermine probable cause.”
Shadwick v. City of Tampa,
2. The Challenged Warrant Is Not Facially Deficient
In
Leon,
the Supreme Court observed that “a warrant may be so facially deficient — i.e., in failing to particularize the place to be searched or the things to be sеized — that the executing officers cannot reasonably presume it to be valid.”
Id.
at 923,
Massachusetts v. Sheppard,
In
Groh v. Ramirez,
agents submitted for approval a warrant that erroneously described the suspect’s residence in the area reserved for identification of the items to be seized. Although the warrant affidavit detailed the latter information, the Court concluded that its complete absence from the warrant precluded reasonable reliance.
See
The warrant here contains no similar defect. It specifically identified the place to be searched — “1015 Fairfield Ave, being a multi family dwelling located on the south side of Fairfield Avе and located on SBL# 144.31-3-26, in the City of Niagara Falls, New York.” Warrant at 1. It specifically identified the items that could be seized:
Cocaine and any other controlled substances as defined in Article 220 and 221 of the Revised Penal Laws of the State of New York, as well as for any imple *103 ments used to administer same, or prepare same for packaging or sale or other dispensation of aforementioned substances, as well as for any monies, all written papers or articles, or keys, or any other papers that tend to show that crimes relating to violation of Article 220 and 221 of the Revised Penal Laws of the State of New York have been committed.
Id.
To be sure, the Constitution further requires that warrants be issued only “upon probable cause,” but it does not require that probable cause be stated in the warrant itself.
See, e.g., United States v. Grubbs,
3. The Warrant Affidavit Was Not So Lacking in Indicia of Probable Cause as To Preclude Reasonable Reliance
Leon
instructs that officers cannot reasonably rely on a warrant issued on the basis of an affidavit “ ‘so lacking in indicia of probable cause as to render official belief in its existence entirely unreasonable.’ ”
United States v. Leon,
Such a concern most frequently arises when affidavits are bare bones,
ie.,
totally devoid of factual circumstances to support conclusory allegations.
Cf. United States v. Leon,
At the opposite end of the spectrum are cases in which a defective warrant issued based on an affidavit providing detailed factual allegations in support of probable cause. Such cases almost invariably demonstrate reasonable reliance. As the Supreme Court explained in
Leon,
“[i]t is the magistrate’s responsibility to determine whether the officer’s allegations establish probable cause.... In the ordinary case, an officer cannot be еxpected to question the magistrate’s probable-cause determination .... ”
Id.
at 921,
This case falls somewhere in between these two extremes. The warrant affidavit was not completely bare bones. It provided sufficient details to рermit the issuing judge to find probable cause to believe that Clark was dealing drugs from somewhere within 1015 Fairfield Avenue. In addition to reporting that an untested informant had ascribed such conduct to Clark and that surveillance officers had witnessed Clark entering and remaining inside the suspect premises on multiple occasions, the affidavit detailed two controlled buys made by the informant directly from Clark at or very near the subject property.
13
Further, in seeking leave to search the property, the warrant affidavit candidly advised the issuing judge that 1015 Fair-field Avenue was a multi-family dwelling,
cf. United States v. Reilly,
A problem arises only when we consider the allegations of control in the warrant application. Ascribed to an informant (“full control”) and surveillance officers (“exercising control”), the allegations are entirely conclusory. Warrant Aff. at 2. We have already explained why such conclusory assertions about a concept that can be manifested in different ways and to different degrees depending on circumstances were insufficient to permit the issuing judge to find probable cause to search the entirety of a building containing an undisclosed number of residential units.
See supra
at 95-98. Nevertheless, we are not persuaded that law enforcement conduct here was so “flagrant” or “culpable” in violating Fourth Amendment rights as to compel suppression.
Herring v. United States,
In reaching this conclusion, we note that, before the district court, Clark appears to have challenged only the specificity of the government’s control allegations,
*105
not their
bona fides.
14
At the time the warrant issued, however, the need to allege control with some factual specificity appears not to have been the subject of discussion in prior precedent from this оr other courts. As we have already observed, in
People v. Tambe,
the New York Court of Appeals cautioned that the rule it there recognized allowing for a search of all premises “in the control of’ various criminal associates to find evidence “likely to be in the possession of one of them” might “be different” if such searches “would intrude upon the rights of individuals in no way involved in the criminal activity under investigation.”
In sum, because the warrant affidаvit was not completely bare bones, because the issuing judge was told the premises to be searched was a multi-family dwelling, because control can be a factor relevant to assessing probable cause to search the whole of such premises, and because the need to support an allegation of control with descriptive facts was not previously established in precedent, we conclude that the application was not “so lacking in indicia of probable cause as to render official belief in its existence entirely unreasonable.”
United States v. Leon,
III. Conclusion
To summarize, we conclude as follows:
1. Because “control” is a concept that can be manifested in various ways and to different degrees, conclusory allegations that defendant “controlled” a multi-family dwelling were insufficient to allow a judge to find probable cause to search each of *106 the unspecified number of residences in the building.
2. Defendant’s motion to suppress evidence derived from the invalid search should have been denied pursuant to the good faith exception to the exclusionary rule recognized in
United States v. Leon,
(a) the issuing judge did not abandon his neutral and detached judicial role in mistakenly finding probable cause to support the challenged warrant,
(b) the warrant was not facially invalid, and
(c) the warrant affidavit was not completely bare bones and the need to support a conclusory allegation of “control” with specific facts not so established in law as to preclude the police from reasonably relying upon the validity of the challenged warrant in this case.
Suppression order Reversed and case Remanded for further proceedings consistent with this opinion.
Notes
. While the scope of the warrant might raise concerns as to both persons and place, because no evidence seized from third parties is here at issue, we need only consider whether there was a substantial basis for finding probable cause to search the entire building.
. The government reiterates on appeal a point made in the district court: that the informant’s reliability was unknown at the time of his first meeting with police, but thereafter was corroborated by the police surveillance and two controlled purchases of drugs discussed in the warrant affidavit.
. The fact that the identified items were seized from the downstairs apartment was disclosed by the government at oral argument on the suppression motion. Although the record lacks explicit evidence as to the number of residential units located at 1015 Fairfield Avenue, at several points during the suppression proceedings the government made statements that suggest there were only two apartments in the building. See Pretrial Motions Hr'g 22:16-19 (Feb. 19, 2009) ("[T]hey found the defendant in the downstairs ... they didn't get anything from the upstairs....''); id. at 6:16-18 ("If there are two apartments, if he exercises dominion and control over both apartments, I dоn’t know what we can say in terms of he doesn't have standing.”); id. at 8:21-23 ("And I have a feeling, again, that he basement would be accessible from either apartment.”). Our focus, however, is on the information provided to the judge who issued the warrant, not on the information provided to the judge presented with a suppression motion.
. Although Clark initially moved to suppress his statement on the ground that he was not given Miranda warnings, he subsequently withdrew that argument, making it unnecessary for us to discuss it here.
.
Bermudez
nevertheless held that the suppressed evidence could be used for purposes of impeachment.
See
. A subsequent suppression hearing revealed that defendant had to pass through the lower floor apartment — which was vacant at the time of the search — to reach the second floor apartment.
See United States v. Gusan,
. While control was only part of the probable cause presentation in this case, it was the only part that supported a search of the entire multi-family dwelling, as opposed to a residence specifiсally linked to the defendant.
. Notably absent from the warrant affidavit is any allegation as to where the informant said the controlled purchases occurred, information about which he presumably had direct knowledge.
. The government submits that any error in issuing so broad a search warrant was necessarily harmless because incriminating evidence was seized only from the ground floor apartment wherein Clark was found. To the extent this might be construed to suggest that probable cause existed at least for that apartment, we are not persuaded. The govern-men! was obliged to demonstrate probable cause to search a particular apartment before securing the warrant, not after executing it. Moreover, we note that the government did not specifically deny searching other residences in executing the warrant; it simply denied making any seizures therefrom.
. Nevertheless, the Court concluded that the officer’s reliance on the warrant was reasonable because the officer had brought the defect to the attention of the issuing judge, who had represented that he would correct it, but then failed to do so unbeknownst to the officer.
See Massachusetts
v.
Sheppard,
.
Groh
was a civil action under
Bivens v. Six Unknown Fed. Narcotics Agents,
. While it might have been preferable for the affidavit to disclose not only surveillance observations of the buys — which were less than detailed — but also the informant’s account of where the buys actually occurred, the allegations were sufficient to demonstrate probable cause to believe that evidence of Clark’s criminality would be found somewhere in 1015 Fairfield Avenue.
See Walczyk v. Rio,
. Thus, we have no reason to remand for the district court to ascertain what facts supported the allegation of control in order to determine whether a well-trained officer aware of those facts could, in good faith, have alleged control.
