OPINION
After receiving complaints of odors of drugs from apartment-complex employees, law-enforcement officers performed a dog sniff in a common hallway of appellant’s apartment. The dog alerted to the odor of illegal drugs. The officers then obtained and executed a search warrant and seized drugs and drug paraphernalia frоm appellant’s apartment. The district court denied appellant’s motion to suppress the evidence seized from the search. On appeal, appellant argues that the dog sniff was a search that required probable cause or, alternatively, that a reasonable, articu-lable suspicion did not exist. We affirm.
*844 FACTS
In August 2004, employees of the apartment complex in which appellant Scott Evan Davis resided informed agents of the Dakota County Drug Task Force that they had observed activated growing lights in Davis’s apartment and believed he was growing marijuana. They also stated that they had attempted to investigate a water leak inside Davis’s apartment but that he did not permit them to enter. According to the search-warrant application, a drug-sniffing dog was brought to the apartment complex to “investigate the odor of narcotics on the first floor” and alerted to the presence of illegal drugs at the “threshold of [Davis’s] apartment.” Based upon the observations of the apartment-complex employees and the dog’s alert, agents werе issued a no-knock search warrant. The agents executed the warrant on Davis’s apartment using a key provided by apartment-complex management. The agents discovered and seized marijuana, drug paraphernalia, a mushroom-growing kit, and a handgun. Davis was arrested and charged with controlled-substance crimes for possession of marijuana and drug paraphernalia.
Davis brought a motion to suppress the evidence, alleging that it was obtained in violation of his federal and state constitutional rights. The district court denied Davis’s motion and concluded that there was (1) a reasonable, articulable suspicion of illegal activity to support “using a drug-sniffing canine in the common hallway put-side [Davis’s] apartment” and (2) adequate probable cause, based on the dog sniff and the employees’ observations of the growing lights, to support the issuance of a search warrant of his apartment. Davis then entered a not-guilty plea, submitted the matter to the district court under
State v. Lothenbach,
ISSUES
1. Does use of a drug-sniffing dog in the common hallway of an apartment building constitute a search that requires probable cause under the federal and state constitutiоns?
2. If probable cause is not required, did a reasonable, articulable suspicion exist to conduct the dog sniff in the common hallway of the apartment building?
ANALYSIS
I.
Davis first argues that probable cause must exist before law enforcement can conduct a dog sniff “at [his] apartment door.” The district court decided that the “more persuasive cases have found that a canine sniff of a common hallway in an apartment building has Fourth Amendment implications and must be supported by reasonable articulable suspicion.” Davis bases his argument on the premise that a residence has a greater privacy protection against searches than a seized vehicle or a storage unit. He concludes that, becausе probable cause should be required, the warrantless dog sniff violated his federal and state constitutional rights, and the evidence seized as a result of the warrant should be suppressed.
When reviewing pretrial orders on motions to suppress evidence, appellate

courts “independently review the facts and determine, as a matter of law, whether the district court erred in suppressing — or not suppressing — the evidence.”
State v. Harris,
The expectation-of-privacy element, however, has been subjected to fine line drawing. The United Statеs Supreme Court has found diminished expectations of privacy in luggage in a public airport and in a barn that is outside of a home’s “curtilage.”
See Place,
We conclude that a dog sniff in a common hallway is not a Fourth Amendment search. Davis does not have a reasonable expectation of privacy in the common hallway of the apartment building. The dog sniffs level of intrusiveness was minor. First, the search-warrant application refers to “the odor of narcotics on the first floor.” This observation was made before any dog sniff and suggests that the odor of narcotics existed in the hallway and was detectable through a human being’s sense of smell. Second, we disagree with Davis’s characterization that the dog “detected] the presence of illegal narcotics inside [Davis’s] home.” The evidence in the record shows that the dog sniffed only in the common hallway. The detected scent may have originated from within Davis’s apartment, but it was detected outside the apartment by the dog.
Davis relies on
United States v. Thomas,
But our analysis does not end with the Fourth Amendment. We must also determine whether the dog sniff was a search under the Minnesota Constitution.

The Minnesota Supreme Court has addressed dog sniffs on two recent occasions. It first ruled that a dog sniff of the exteri- or of an automobile legitimately stopped for a traffic offense is not a search requiring probable cause.
State v. Wiegand,
In 2005, the supreme court addressed a dog sniff around the exterior of an individual storage unit at a self-storage facility.
State v. Carter,
[A] narcotics detection dog may be deployed tо test for the presence of narcotics [in the area outside a storage unit] where:
1. the police are able to articulate reasonable grounds for believing that drugs may be present in the place they seek to test; and
2. the police are lawfully present in the place where the canine sniff is conducted.
Id. at 212. This standard properly bаlances a “person’s privacy interests against the public’s interest in effective criminal investigations.” Id. at 211.
We conclude that a dog sniff in the common hallway of an apartment building is a search under the Minnesota Constitution that requires only a reasonable, artic-ulable suspicion. This conclusion is compelled by the supreme court’s statement that the “permissibility of the use of dogs in other settings for other purposes must be evaluated based on whether the privacy expectation is one society is willing to deem reasonable, and not on subjective perceptions of the intrusiveness of the investigative method.”
Wiegand,
Davis relies on the United States Supreme Court’s decision in
Kyllo v. United States,
II.
Alternatively, Davis argues a reasonable, articulable suspicion did not exist for a dog sniff. The district court ruled that the information received from the apartment-complex employees provided a reasonable, articulable suspicion to justify the sniff.
Reasonable, articulable suspicion is determined by reviewing the totality of the circumstances.
State v. Martinson,
The law-enforcement officer first leаrned from employees of the apart-
ment complex that activated growing lights had been observed in Davis’s apartment and that Davis would not permit their entry into his apartment to investigate a possible water leak. Private-citizen informants are “presumed to be reliable.”
Marben v. State, Dep’t of Pub. Safety,
Davis argues that the presence of activаted growing lights could only raise a hunch of drug-related activity and is no different than a marijuana symbol on a key chain.
See State v. Tomaina,
We note the difficulty under which law enforcement operates in attempting to determine whether a dog sniff is a search under the federal or state constitutions. Perhaps our decision today offers clear guidance in the context of an apartment complex: a dog sniff in the common hallway of an apartment is permissible so long as law enforcement has a reasonable, artic-ulable suspicion of drug-related activity.
DECISION
'The dog sniff in the common hallway of the apartment complex was not a search under the Fourth Amendment. The dog sniff was a search under the Minnesota Constitution that required a reasonable, articulable suspicion of drug-related activity. A reasonable, articulable suspicion existed from the information provided by the apartment-complex employees that appellant hаd activated growing lights in his apartment.
Affirmed.
