OPINION
¶ 1 The state appeals the trial court’s grant of Ryan Ray Olm’s motion to suppress evidence obtained in a warrantless search of his vehicle. The state argues Olm had no protected privacy interest in the front yard of *431 his home where the vehicle had been parked. Finding no error, we affirm.
Factual and Procedural Background
¶ 2 In reviewing the denial of a motion to suppress evidence, we consider only the evidence presented at the suppression hearing,
State v. Blackmore,
¶ 3 The officer walked onto the yard, approximately ten to fifteen feet away from the concrete walkway, to the left side of the Mustang. He looked at the VIN plate through the Mustang’s front windshield, and saw that the plate was slightly bent. The officer then went to the front door of the house and “tried to make contact with the residents.” When no one responded, the officer contacted one of the detectives and reported the bent VIN plate on the Mustang. The detective then told the officer to seize the Mustang, and the Mustang was soon towed to an impound lot. After searching the Mustang while it was at the impound lot, and after acquiring from Olm the key to its ignition, a detective drove it to an automobile dealership for further inspection “to identify specifically what parts were nonstandard Mustang parts that were on the vehicle.”
¶ 4 A grand jury charged Olm with theft by control of a vehicle, in violation of AR.S. § 13-1802(A)(5), and “conducting a chop shop,” in violation of A.R.S. § 13-4702(A)(5), by buying, selling, or possessing a vehicle with a “removed, destroyed, defaced, or otherwise altered” VIN. Olm filed a motion to suppress all the evidence discovered during and as a result of the inspection and search of the Mustang. After an evidentiary hearing, the trial court, in granting Olm’s motion, determined the yard was part of the curtilage of Olm’s residence and the officer had therefore conducted a warrantless search by “walking onto [Olm]’s private property for the purpose of viewing the VIN plate.” The court granted the state’s motion to dismiss the charges without prejudice, and this appeal followed. See A.R.S. § 13-4032(6).
Discussion
¶ 5 The Fourth Amendment guarantees “[t]he right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” “Unlawful entry of homes was the chief evil which the Fourth Amendment was designed to prevent.”
State v. Ault,
¶ 6 The state argues Olm had no reasonable expectation of privacy in his front yard and that the yard was not part of the home’s curtilage. Although the state presents these concepts as two distinct issues, they are closely interrelated. If the yard was not *432 part of the curtilage of Olm’s house, he had no reasonable expectation of privacy in the area where the Mustang had been parked. And, as we will explain, if the yard was part of the curtilage, the pertinent question is whether the officer viewed the Mustang’s VIN plate from a legal vantage point. Before we reach those questions, however, we must first determine the proper standard of review.
¶ 7 In reviewing a trial court’s ruling on a motion to suppress, we defer to the trial court with respect to the factual determinations it made but review the court’s legal conclusions de novo.
State v. Gonzalez-Gutierrez,
¶ 8 As to the determination of the extent of the curtilage, the majority of courts we have surveyed view this also as a legal conclusion subject to de novo review.
See, e.g., United States v. Davis,
¶ 9 The Supreme Court in
Ornelas,
when considering determinations of probable cause and reasonable suspicion, stated that review must be de novo because “the legal rules for [such determinations] acquire content only through application” and therefore “[i]ndependent review is ... necessary if appellate courts are to maintain control of, and to clarify, the legal principles.”
¶ 10 The state argues the front yard where the Mustang was parked was not part of the curtilage of Olm’s house and thus he had no privacy interest in that area.
See Oliver,
¶ 11 Here, the yard was not enclosed and Olm took no steps to protect it from observation. But the portion of the yard where Olm parked his Mustang directly abutted the home’s front patio. And, despite the state’s assertion to the contrary, there was no evidence the yard was regularly traversed by members of the public in order to “walk[ ] to the front door.” Indeed, the evidence demonstrates the area was used as a parking area for Olm’s private vehicle, for the express purpose of protecting it from the public. There was no evidence visitors to Olm’s house used the front yard for parking or any other purpose.
¶ 12 Moreover, as the Supreme Court noted in
Dunn,
“for most homes, the boundaries of the curtilage will be clearly marked; and the conception defining the curtilage — as the area around the home to which the activity of home life extends — is a familiar one easily understood from our daily experience.’ ”
¶ 13 That the yard was within the house’s curtilage does not end our inquiry. Residents generally do not have a legitimate expectation of privacy in a path across their driveway to and including their front porch and front door, because that area is implicitly open to the public, thereby “necessarily negating] any reasonable expectancy of privacy in regard to observations made there.”
Lorenzana v. Superior Court,
¶ 14 It is undisputed that the officer could not see the Mustang’s VIN plate from the street, the sidewalk, the concrete walkway leading to the front door, or from the area by the front door. In order to see the VIN plate, the officer had to enter the yard. The state argues that, because the yard was actually used as a driveway, it is a semiprivate area the officer could enter without invitation or justification.
See State v. Cobb,
¶ 15 We disagree. The concrete walkway clearly delineated the path guests were expected to take from the street or sidewalk to Olm’s front door. It was not necessary for the officer, or any member of the public, to leave the walkway in order to reach Olm’s front door. And, as we explained above, no reasonable member of the public would believe he or she had permission to enter the yard to peer into the vehicle. The mere fact that Olm parked his private vehicle in his yard, thus arguably converting that area to a semiprivate area, does not compel a different conclusion. Driveways are considered semiprivate areas not because members of the public reasonably could enter them without explicit permission, but because the activities and items in a driveway generally are more readily observable.
See Dugan,
¶ 16 The state also contends Olm had no reasonable expectation of privacy in the yard because it was not enclosed. But the state cites no authority, and we find none, suggesting that merely because a private residential yard is unenclosed, law enforcement officers are thereby permitted to enter that yard to conduct a warrantless search absent an exception to the warrant requirement not present here. The cases upon which the state relies are readily distinguishable.
See State v. Platt,
¶ 17 Accordingly, we conclude the front yard area where Olm’s Mustang was parked was part of his house’s curtilage, and that, by entering the yard, the officer was not in a lawful viewing position when he saw the Mustang’s VIN plate. His doing so was a prohibited warrantless search. The trial court therefore did not err in granting 01m?s motion to suppress evidence.
Disposition
¶ 18 We affirm the trial court’s grant of Olm’s motion to suppress evidence.
