       JOHN K. BUSH, Circuit Judge. Christopher May-Shaw was sentenced to 144 months in
prison after he entered a conditional guilty plea to a charge of conspiracy to distribute cocaine.
 No. 18-1821                       United States v. May-Shaw                              Page 2


The conviction arose from police surveillance of a parking lot near his apartment building and a
covered carport next to that building, where May-Shaw parked his BMW, one of his several
vehicles. The surveillance lasted for twenty-three days and used a camera affixed to a telephone
pole on a public street and cameras in a surveillance van parked in the parking lot. After
witnessing May-Shaw engage in several suspected drug deals, the police used a drug-detecting
dog to sniff the BMW. The dog indicated the presence of narcotics in the vehicle. Based on the
dog sniff and the surveillance, the officers obtained a search warrant for May-Shaw’s apartment
and all of his vehicles. The search found evidence of drug distribution, including cash, wrappers,
and cocaine. The district court denied his motion under the Fourth Amendment to suppress the
evidence from his apartment and vehicles. May-Shaw then entered a conditional guilty plea for
conspiracy to distribute cocaine, but he preserved the right to appeal the denial of his motion to
suppress.

       As explained below, May-Shaw did not have a reasonable expectation of privacy in the
carport such that police surveillance constituted a search in violation of the Fourth Amendment.
Nor was the carport within the curtilage of his apartment such that the dog sniff was
unconstitutional. Therefore, we AFFIRM the district court’s denial of May-Shaw’s motion to
suppress.

                                                I.

       In December 2015, the City of Grand Rapids Police Department began investigating
May-Shaw for suspected involvement in drug trafficking. The Department had received tips
from Silent Observer—an organization that receives anonymous information from the public—
describing vehicles May-Shaw was using to transport drugs and a specific bag where he kept
drugs, money, and a gun. A criminal history check on May-Shaw revealed that he had one
felony firearm conviction and two felony drug convictions. Based on all of this information, the
Grand Rapids police decided to conduct surveillance of the exterior of May-Shaw’s apartment
building and the parking lot of the apartment complex.

       The apartment where May-Shaw lived is one of several units in the complex, which itself
abuts a communal parking lot. In the parking lot are covered carports, the interiors of which are
 No. 18-1821                        United States v. May-Shaw                             Page 3


easily viewable from a public vantage point on Norman Drive, a road outside of the parking lot.
May-Shaw often parked his vehicles under a covered carport close to the entrance to his
apartment building.    Nothing in the record indicates whether the carport was specifically
assigned to him, or if he had just consistently parked there.

       The carport is next to a parking lot that is accessible only from Norman Drive, and that
entrance affords almost complete visibility of the lot and adjacent apartment complex. The
owner of the complex gave police permission to conduct physical and video surveillance of the
lot. They had a good view, for only a line of trees obstructs the parking lot from public view on
the road, and there was no foliage obstructing the view in February 2016, when the surveillance
occurred.

       Most of the stakeout, lasting several weeks, was done from a van using remotely operated
cameras. Officers would park the van in the lot, moving its location every day or two. Through
this method, police observed May-Shaw loading and unloading drugs and cash from his BMW
and engaging in what officers believed to be drug deals in the parking lot.

       In addition to their surveillance from the van, on January 26, 2016, police installed a
camera on a telephone pole on Norman Drive. Officer Mesman, the principal investigator in
May-Shaw’s case, testified as to the specifics of the pole camera. According to Mesman, the
camera was affixed to the pole approximately twenty feet from the ground, and could pan from
side to side and up and down. The camera, which recorded continuously for twenty-three days,
could produce video as well as still shots. Though officers did not monitor the footage
continuously in real time, they reviewed the footage they missed by watching the recorded video.

       The pole-camera and van-camera footage captured May-Shaw engaging in what the
officers suspected were drug transactions in the parking lot. They based this conclusion on
observations of May-Shaw making brief contact with people inside their vehicles, during which
time he and the person in the car exchanged something. Also, on several occasions May-Shaw
retrieved what appeared to be evidence of drug distribution from his vehicles. For example, on
February 17, 2016, officers observed him lean into the front passenger side of one of his vehicles
and remove cash and a bag of suspected drugs, hide the items under his jacket, and carry them
 No. 18-1821                         United States v. May-Shaw                            Page 4


inside the apartment. The next day, officers watched May-Shaw reach into the back of his car
and remove a large stack of cash, which he also took inside the apartment. Soon thereafter, the
officers saw him put another two bags, which they also suspected contained drugs and cash, in
the trunk of his BMW.

       After witnessing such suspected drug transactions, the officers called in a K-9 unit for a
drug-detecting dog sniff of the BMW, where the officers had just seen May-Shaw stash the bags.
When the dog circled the BMW, which was parked directly under the carport, it alerted the
officers to the odor of narcotics.

       Based on the surveillance and dog sniff, the officers sought a search warrant. The police
relied primarily on the footage from the pole camera and the surveillance van, which showed
different angles of the same conduct described earlier. A state magistrate judge authorized a
search warrant for the apartment and three vehicles connected to May-Shaw. The apartment
search resulted in seizure of almost $2,000 in cash, a gun, drug paraphernalia and packaging
material, and nearly a pound of marijuana. In their search of the BMW, police found a kilogram
of cocaine, some fentanyl, and over $200,000 in cash. The search of one of May-Shaw’s other
vehicles, a Chevrolet Tahoe, turned up another $486 in cash. Neither May-Shaw nor his third
car was present when the police conducted the search. May-Shaw was arrested some months
later in Brooklyn, New York.

       A federal grand jury in the U.S. District Court for the Western District of Michigan
returned a superseding indictment charging May-Shaw with conspiracy to distribute and possess
with intent to distribute cocaine, possession with intent to distribute cocaine, and maintaining
drug-involved premises, in violation of 21 U.S.C. §§ 846, 841(b)(1)(A) and 856.

       May-Shaw moved the district court to suppress the evidence seized pursuant to the search
warrant, arguing that the warrantless surveillance through the pole camera and the warrantless
sniff by the drug-detecting dog of the BMW constituted unconstitutional warrantless searches.
The district court denied the motion, holding that (1) May-Shaw had no reasonable expectation
of privacy in the parking lot; (2) the area surveilled by the pole camera was not constitutionally
protected curtilage of the apartment; (3) the dog sniff was permitted under the Fourth
 No. 18-1821                         United States v. May-Shaw                              Page 5


Amendment; and (4) even if the dog sniff was unconstitutional, the remainder of the information
in the warrant affidavit was sufficient to support probable cause for the search warrant.

       May-Shaw entered a conditional guilty plea to the conspiracy count, preserving the right
to appeal the denial of the motion to suppress. He was sentenced to 144 months in prison. He
filed this timely appeal.

                                                II.

       When reviewing a district court’s decision on a motion to suppress, we use a mixed
standard of review, reviewing findings of fact for clear error and conclusions of law de novo.
United States v. Hines, 885 F.3d 919, 924 (6th Cir. 2018). Evidence should be viewed in the
light most favorable to the district court’s conclusions. United States v. McCraney, 674 F.3d
614, 616–17 (6th Cir. 2012). “[A] denial of a motion to suppress will be affirmed on appeal if
the district court’s conclusion can be justified for any reason.” United States v. Moorehead,
912 F.3d 963, 966 (6th Cir. 2019) (alteration in original) (quoting United States v. Pasquarille,
20 F.3d 682, 685 (6th Cir. 1994)).

       May-Shaw’s motion to suppress invokes the Fourth Amendment, which protects “[t]he
right of the people to be secure in their persons, houses, papers, and effects, against unreasonable
searches and seizures.”     U.S. Const. amend. IV.        May-Shaw maintains that his Fourth
Amendment rights were violated when the police conducted warrantless surveillance of the
carport outside of his apartment, and when they used a drug-detecting dog to sniff his car that
was parked in that carport. We address each argument in turn.

                                                A.

       May-Shaw argues that the district court erred in finding that the long-term surveillance of
the carport did not constitute a search. Under Fourth Amendment jurisprudence, there are two
ways in which government action may constitute a search. First, when the government gains
information by physically intruding into a constitutionally protected area—namely, “persons,
houses, papers, and effects,” U.S. Const. amend. IV—“‘a search within the original meaning of
the Fourth Amendment’ has ‘undoubtedly occurred.’” Morgan v. Fairfield Cty., 903 F.3d 553,
 No. 18-1821                       United States v. May-Shaw                               Page 6


561 (6th Cir. 2018) (quoting Florida v. Jardines, 569 U.S. 1, 5 (2013)). Second, as articulated
by the Supreme Court, a search occurs when “a government official invades an area in which ‘a
person has a constitutionally protected reasonable expectation of privacy.’” Taylor v. City of
Saginaw, 922 F.3d 328, 332 (6th Cir. 2019) (quoting Katz v. United States, 389 U.S. 347, 360
(1967) (Harlan, J., concurring)). Under the latter framework, there are two requirements for a
government intrusion to constitute a Fourth Amendment search: first, a person must exhibit “an
actual (subjective) expectation of privacy” in the place or thing searched; second, the expectation
is one “that society is prepared to recognize as ‘reasonable.’” Katz, 389 U.S. at 361.

       Because the officers’ use of the pole camera did not involve any sort of physical intrusion
into a constitutionally protected area, May-Shaw must show that he had a reasonable expectation
of privacy in the carport. Cobbling together dicta from several Fourth Amendment cases, he
argues that, although police may permissibly observe the curtilage of a home for a short period
of time, for example with an aerial flyover, see California v. Ciraolo, 476 U.S. 207, 213 (1986),
long-term video surveillance of a home’s curtilage is problematic under the Fourth Amendment,
see United States v. Anderson-Bagshaw, 509 F. App’x 396, 405 (6th Cir. 2012). There is at least
some support for that proposition, as this court and five Justices of the Supreme Court have
noted concerns about the problems with long-term warrantless surveillance. See id.; see also
United States v. Jones, 565 U.S. 400, 415, 429–30 (2012) (Sotomayor, J., concurring and Alito,
J., concurring).

       Although this argument may be compelling in theory, as applied here, it is foreclosed by
this circuit’s case law, which has consistently held that this type of warrantless surveillance does
not violate the Fourth Amendment. For example, in United States v. Houston, we held that
affixing a video camera to the top of a utility pole to record the defendant’s front porch over a
ten-week period did not violate the defendant’s Fourth Amendment rights because “agents only
observed what [the defendant] made public to any person traveling on the roads” surrounding his
home. 813 F.3d 282, 288 (6th Cir. 2016). We rejected the defendant’s claim that the length of
the period of monitoring made the surveillance constitutionally unreasonable, reasoning that it is
the possibility—not the practicability—that the police could have themselves sat atop the utility
pole and observed the same view for every waking moment of a ten-week period that is critical.
 No. 18-1821                             United States v. May-Shaw                                        Page 7


Id. at 289–90. That reasoning was applied in United States v. Powell, in which we held that the
warrantless surveillance of three buildings through the installation of video cameras on three
public utility poles, for periods of up to 90 days each, did not violate the defendants’ Fourth
Amendment rights. 847 F.3d 760, 773 (6th Cir. 2017). And, even assuming that May-Shaw is
correct that the carport constitutes the curtilage of his apartment—an argument that we find
unpersuasive, for reasons discussed below—that is of no consequence to the constitutional
analysis of the video surveillance. We held in Houston that warrantless video surveillance of the
defendant’s front porch, which is unquestionably within the curtilage of his home, did not violate
his reasonable expectation of privacy because the camera “captured only views that were plainly
visible to any member of the public who drove down the roads bordering” his home. Houston,
813 F.3d at 288.

        May-Shaw contends that the pole camera did not provide the same vantage point that was
readily accessible from the street.1 The district court, however, held that the area surveilled by
the pole camera was readily accessible from a public vantage point. This is a factual finding that
is reviewed for clear error. Officer Mesman testified that the vantage point from the pole camera
was the same as the vantage point from the street, and nothing in the record contradicts that
assertion. Therefore, the district court’s factual finding that the pole camera recorded the same
view enjoyed by an individual standing on Norman Avenue was not clearly erroneous.

        Furthermore, the surveillance footage and photos here did not “generate[] a precise,
comprehensive record of [May-Shaw’s] public movements that reflects a wealth of detail about
[his] familial, political, professional, religious, and sexual associations,” Jones, 565 U.S. at 415


        1The     parties dispute which camera or cameras recorded the illicit activity. May-Shaw claims that the
footage was captured by the pole camera, whereas the government maintains that the incriminating footage came
from the cameras in the van. Though the officers did not keep a log of which images came from each camera, a
comparison of two sets of photos available at R. 60-2, PageID 236–37 clearly indicates that the close-up images
showing May-Shaw engaged in suspected drug transactions did not come from the more remote camera affixed to
the telephone pole. May-Shaw does not point to anything other than the lack of a log to suggest that the images did
not come from the surveillance van cameras. Appellant Br. at 13. If the images were in fact recorded from the
surveillance van rather than from the pole camera, then this is a simple case of police surveillance from a publicly
accessible area, in which the police had permission to conduct the surveillance. This does not raise the same Fourth
Amendment concerns. See United States v. Gooch, 499 F.3d 596, 602–03 (6th Cir. 2007) (noting that an individual
does not have a reasonable expectation of privacy in an openly accessible parking lot, and so police surveillance in
that lot did not constitute a search).
 No. 18-1821                       United States v. May-Shaw                              Page 8


(Sotomayor, J., concurring), which could raise significant Fourth Amendment concerns. Rather,
the footage and photos only revealed what May-Shaw did in a public space—the parking lot.
They captured images of May-Shaw moving things from his car to his apartment. The video
showed when he arrived and left the apartment. In other words, the cameras observed only what
“was possible for any member of the public to have observed . . . during the surveillance period.”
Houston, 813 F.3d at 290.

       May-Shaw has not demonstrated that when the government surveilled the carport for
twenty-three days, it violated his reasonable expectation of privacy and thus conducted an
unconstitutional search. We find no error in the district court’s judgment that the pole-camera
surveillance did not violate May-Shaw’s Fourth Amendment rights.

                                               B.

       May-Shaw also argues that the district court should have granted his motion to suppress
because the use of the drug-detecting dog to sniff his BMW while it was parked in the carport
constituted an unlawful search under the Fourth Amendment. This argument hinges on one
issue: whether the carport where the vehicle was parked constitutes the curtilage of the
apartment.

       As relevant here, the Fourth Amendment protects the people from “unreasonable
searches” of “their . . . houses.” And, as a general rule, the curtilage of a home is protected by
the Fourth Amendment. See United States v. Dunn, 480 U.S. 294, 300 (1987); see also Jardines,
569 U.S. at 6 (noting that the area “immediately surrounding and associated with the home” is
“part of the home itself for Fourth Amendment purposes” (quoting Oliver v. United States, 466
U.S. 170, 180 (1984))). That rule is well-rooted in history. “At the founding, curtilage was
considered part of the ‘hous[e]’ itself.” Collins v. Virginia, 138 S. Ct. 1663, 1676 (2018)
(Thomas, J., concurring) (alteration in original) (quoting 4 W. Blackstone, Commentaries on the
Laws of England 225 (1769) (“[T]he capital house protects and privileges all its branches and
appurtenants, if within the curtilage.”)). “The protection afforded the curtilage is essentially a
protection of families and personal privacy in an area intimately linked to the home, both
 No. 18-1821                       United States v. May-Shaw                               Page 9


physically and psychologically, where privacy expectations are most heightened.” Id. at 1670
(majority opinion) (quoting Ciraolo, 476 U.S. at 212–213).

       Although it is well-settled that the warrantless search of a home’s curtilage with a drug-
sniffing dog violates the Fourth Amendment, Jardines, 569 U.S. at 11–12, what constitutes
curtilage for purposes of the Fourth Amendment generally, and in the present case in particular,
are harder questions. If the carport was within the curtilage of May-Shaw’s apartment, then the
dog sniff constituted an unconstitutional warrantless search under Jardines, but if the carport was
not within the curtilage, then the sniff was not a search, and therefore was not constitutionally
problematic. See United States v. Perez, 440 F.3d 363, 375 (6th Cir. 2006) (holding that using a
drug-sniffing dog on a car parked in a hotel parking lot, which was not stopped, detained, or
moved, did not constitute a search).

       Courts have identified four factors as guideposts to determining whether an area falls
within a home’s curtilage: (1) the proximity of the area to the home, (2) whether the area is
within an enclosure around the home, (3) how that area is used, and (4) what the owner has done
to protect the area from observation from passersby. Morgan, 903 F.3d at 561 (citing Dunn, 480
U.S. at 301). These factors are not to be applied mechanically; rather, they are “useful analytical
tools only to the degree that, in any given case, they bear upon the centrally relevant
consideration—whether the area in question is so intimately tied to the home itself that it should
be placed under the home’s ‘umbrella’ of Fourth Amendment protection.” Dunn, 480 U.S. at
301. In the application of the factors, the onus is on May-Shaw: he “bears the burden of
establishing that the challenged search violated his Fourth Amendment rights.” United States v.
Coleman, 923 F.3d 450, 455 (6th Cir. 2019) (quoting United States v. Witherspoon, 467 F.
App’x 486, 490 (6th Cir. 2012)).

       The Supreme Court recently held that an enclosed driveway abutting a house constituted
the curtilage of the home. Collins, 138 S. Ct. at 1670–71. In Collins, police searched a
motorcycle that was covered by a tarp and was parked in a section of a driveway that was
partitioned off by two brick walls and a wall of the house itself. Id. at 1670. “A visitor
endeavoring to reach the front door of the house would have to walk partway up the driveway,
but would turn off before entering the enclosure and instead proceed up a set of steps leading to
 No. 18-1821                          United States v. May-Shaw                           Page 10


the front porch.” Id. at 1671. The Court held that the driveway enclosure “constitute[d] ‘an area
adjacent to the home and “to which the activity of home life extends,”’ and so is properly
considered curtilage.” Id. (quoting Jardines, 569 U.S. at 7).

       May-Shaw argues that Collins is dispositive here, and that because the carport was
partially enclosed, it constitutes the curtilage of the apartment. But Collins does not mandate
that result. At least three cases in this circuit cut against May-Shaw’s position.

       First, there is Coleman, mentioned above. There, we found that the defendant’s car was
not within the curtilage of his condo when it was parked in his condominium complex’s
driveway, reasoning in part that the driveway was communal and other condo residents
frequently walked past cars parked in front of the condo units. 923 F.3d at 456–57; see also
United States v. Jones, 893 F.3d 66, 72 (2d Cir. 2018) (“[Collins] has no effect on [the
defendant’s] appeal, which fails because the driveway in which [the defendant’s] vehicle was
parked was the shared driveway of tenants in two multi-family buildings and was not within the
curtilage of [his] private home.”).

       In addition, two Sixth Circuit cases decided prior to Collins—United States v. Galaviz,
645 F.3d 347 (6th Cir. 2011), and United States v. Estes, 343 F. App’x 97 (6th Cir. 2009)—are
instructive. Those cases involved unenclosed driveways that were adjacent to a home, and
abutted a sidewalk or alley, with no steps taken by the resident to obstruct the view of passersby.
Galaviz, 645 F.3d at 356; Estes, 343 F. App’x at 101. In both cases, we held that officers did not
intrude upon the curtilage by entering the driveway. In Galaviz we found that although the
driveway was adjacent to the house, it was not enclosed by any barrier, and the portion where
cars were parked was directly adjacent to a public sidewalk. Galaviz, 645 F.3d at 356. And in
Estes, the driveway was not curtilage because it was not enclosed, the defendant had not taken
any steps to protect it from observation by passersby, and it was used as a point of entry to the
defendant’s residence. Estes, 343 F. App’x at 101.

       May-Shaw directs the court’s attention to several cases—one from the Sixth Circuit, and
three from district courts within our circuit—in an attempt to establish a broad rule that a carport
is always within the curtilage of a home. See Appellant Br. at 26. But each of the cases he cites
 No. 18-1821                       United States v. May-Shaw                              Page 11


is factually distinct. As the first case he cites for that proposition states, “[e]very curtilage
determination is distinctive and stands or falls on its own unique set of facts.” Daughenbaugh v.
City of Tiffin, 150 F.3d 594, 598 (6th Cir. 1998) (alteration in original) (quoting United States v.
Reilly, 76 F.3d 1271, 1276 (2d Cir. 1996))).

       In Daughenbaugh, as May-Shaw notes, our court held that a detached garage was within
the curtilage of a home. Id. at 601. But there, the garage was “within natural boundaries
demarcated by the river and the heavy tree coverage . . . [and] the backyard and garage [were]
not readily visible from the street.” Id. at 599. We considered these natural boundaries to be
compelling evidence that the garage was within the curtilage of the home. Id. Furthermore, the
garage was set far back from the road, and a large tree prevented neighbors, those parked in the
driveway, and those on the street from viewing the interior of the garage. Id. at 600. Important
to the court’s calculus was that the “contents [of the garage] were only visible after a person
entered the backyard and approached the garage.” Id.

       Here, although the carport where May-Shaw parked his vehicles was the closest in
proximity to his apartment, it was not as close to the residence as other structures found to be
curtilage have been. But in any event, that factor is not determinative “without reference to the
additional Dunn factors.” Daughenbaugh, 150 F.3d at 599. In Collins, Coleman, Galaviz, and
Estes, the areas at issue were all driveways that, unlike the carport here, directly abutted homes
or condominiums. And even in those cases where the driveway was connected to the home, the
courts each held that the driveway was not curtilage.

       The second factor—whether the area is an enclosure around the home—also cuts against
May-Shaw. Here, although the area was enclosed, at least to the extent that the carport had a
roof and two side walls, it was not in an enclosure around the residence as was the walled-off
driveway in Collins, nor was it enclosed within natural boundaries of the property like the
detached garage in Daughenbaugh.

       The third factor, which relates to May-Shaw’s use of the carport, arguably weighs in his
favor because, by regularly parking his car in the carport, he contends it was sufficiently
“associated with the activities and privacies of domestic life” to ostensibly support a finding that
 No. 18-1821                        United States v. May-Shaw                              Page 12


it was within the curtilage of his apartment. Dunn, 480 U.S. at 303. However, there is no
evidence that May-Shaw had any legal right to exclude others from the carport.

       Furthermore, May-Shaw did little to protect the area from the view of passersby, and so
the fourth factor weighs against him. With respect to this last consideration, May-Shaw’s case
falls somewhere in between Collins and Coleman. Like the driveway in Collins, the carport here
was partially enclosed, which cuts at least somewhat in his favor. But, like in Coleman, May-
Shaw took no additional steps to protect the area from passersby. He did not, as did the
petitioner in Collins, cover his vehicle to shield it from view from his neighbors. See 138 S. Ct.
at 1668. And because officers could see into the carport from a camera affixed to a utility pole
across a street, it is apparent that May-Shaw did not take significant steps to protect the area from
observation.

       The burden is on May-Shaw to establish that the carport is “intimately linked to the
home, both physically and psychologically, where privacy expectations are most heightened.”
Collins, 138 S. Ct. at 1670 (quoting Ciraolo, 476 U.S. at 212–13). He has not done so. May-
Shaw has failed to establish that the carport constituted the curtilage of his apartment; the drug
dog sniff therefore did not constitute a search. See Perez, 440 F.3d at 375. Because we hold that
neither the pole-camera surveillance nor the dog sniff constituted a search, we need not decide
whether the evidence would have been admissible under the independent-source doctrine or the
good-faith exception.

                                                III.

       May-Shaw has not shown that (1) police surveillance from the pole camera violated his
reasonable expectation of privacy; or (2) the dog sniff constituted an unconstitutional search.
Therefore, we AFFIRM the district court’s denial of his motion to suppress.
