United States v. Perez: Probable Cause Required to Search a Third Party’s Home Under a Supervisee’s Search Condition; Landlord-Ownership Alone Is Insufficient

1. Introduction

In United States v. Augustine Perez (4th Cir. Feb. 23, 2026), the Fourth Circuit confronted a recurring but under-settled Fourth Amendment problem: how far probation/supervised-release search conditions extend when officers target a residence occupied by a third party who is not under court supervision.

The United States brought a civil forfeiture action seeking forfeiture of $25,325 seized during searches connected to federal supervised-release supervision of Augustine Perez. The key third party was Deanna Coleman, Perez’s girlfriend, who leased and occupied a home at 140 Teal Drive that Perez owned but no longer reported as his residence (he reported 721 Lawndale Drive). Probation officers searched Lawndale Drive and then entered Teal Drive over Coleman’s objection, framing the entry as a “probationary search” authorized by Perez’s supervised-release conditions.

The appeal focused on whether the warrantless entry and search of Teal Drive could be justified by Perez’s supervised-release search conditions—despite Coleman’s status as a tenant and her objection—and whether the evidence seized there could support forfeiture.

2. Summary of the Opinion

The Fourth Circuit reversed, holding the Teal Drive warrantless probationary search unconstitutional and ordering suppression in the forfeiture case. It announced two central rules:

  1. A supervised-release condition permitting warrantless searches of a supervisee’s “property” does not authorize officers to search real property owned by the supervisee but leased and occupied by a third-party tenant.
  2. To rely on a supervisee’s search condition to enter and search a residence “not known” to be the supervisee’s home, officers must have probable cause to believe the supervisee resides there; reasonable suspicion is insufficient where third-party home privacy is at stake.

Applying these rules, the court found the Government failed to establish probable cause that Perez lived at Teal Drive at the time of entry. Because the $25,325 was seized at Teal Drive, the court vacated summary judgment for the Government and remanded with instructions to dismiss the forfeiture complaint.

3. Analysis

3.1. Precedents Cited

The court assembled its rule from three doctrinal lines: (i) the sanctity of the home and the warrant presumption; (ii) probation/parole search doctrine; and (iii) third-party home protections in related entry/search contexts.

A. The home’s “special protection” and the warrant presumption

  • Florida v. Jardines and Payton v. New York: The opinion foregrounded the home as “first among equals,” emphasizing that warrantless home entry is the “chief evil” the Fourth Amendment targets. This framing supports using a higher evidentiary threshold (probable cause) before allowing the government to treat a third party’s home as searchable via supervision.
  • United States v. U.S. Dist. Ct. for the E. Dist. of Mich.: Cited through Payton for the proposition that home searches are at the core of the Fourth Amendment’s concerns.
  • Lange v. California, Kyllo v. United States, and Brigham City v. Stuart: Reinforced the default requirement of a warrant supported by probable cause, subject only to carefully bounded exceptions.

B. Probation/parole search doctrine (why supervisees can be searched more easily)

  • Griffin v. Wisconsin: Supported the idea that supervision creates “special needs” that can justify warrantless searches of a probationer’s residence under regulated conditions and a reduced privacy expectation for the supervisee.
  • United States v. Knights: Provided the balancing framework (“totality of the circumstances”) and the commonly cited rule that a probationer’s home can be searched warrantlessly when authorized by a condition and supported by reasonable suspicion.
  • Samson v. California and Penn. Bd. of Prob. & Parole v. Scott: Reinforced the diminished privacy expectations and heightened governmental interests in supervising parolees/probationers to reduce recidivism.

Critically, the court treated these cases as explaining why supervisees’ own privacy interests are diminished—not as blanket authorization to intrude upon the undiminished Fourth Amendment rights of third parties in their homes.

C. Third-party home rights and entry/search safeguards

  • United States v. Brinkley and Steagald v. United States: The linchpin analogy. Brinkley held police must have probable cause that a suspect resides at a home before entering to execute an arrest warrant, because that “reason to believe” requirement is the primary safeguard for third parties. The Perez court imported this protection into the probation-search context: if probable cause is required before entering a third party’s home to execute an arrest warrant, it is likewise required before entering a third party’s home to execute a probationary search condition.
  • United States v. Vasquez-Algarin: Quoted (via Brinkley) for the warning that anything less than probable cause would render “all private homes” vulnerable to entry based on suspicion or uncorroborated tips.
  • United States v. Thabit and United States v. Grandberry: Sister-circuit support for the specific rule adopted—probable cause that the supervisee/parolee resides at the location is required before initiating a warrantless supervision-based search of a residence not known to be the supervisee’s home.
  • Motley v. Parks and United States v. King: Appeared within Thabit’s reasoning to underscore the constitutional risk to third parties and the need for a more rigorous threshold than reasonable suspicion.
  • United States v. Johnson and Griffith v. Kentucky: Used (through Grandberry) to emphasize the Fourth Amendment’s “special protection” for the home.
  • Florida v. Harris and Alabama v. White: Supplied general probable-cause principles—totality-of-the-circumstances assessment and the idea that lower-quality information requires greater corroboration.

D. Consent doctrine and landlord-tenant limits (why ownership did not equal search authority)

  • Illinois v. Rodriguez and United States v. Matlock: Established the consent framework and the role of “common authority” in shared premises searches.
  • Georgia v. Randolph: Highlighted that an occupant’s present objection can defeat consent-based entry (a proxy for “widely shared social expectations” about authority over the home).
  • Chapman v. United States: The core landlord-tenant principle—landlords cannot consent to search a tenant’s home. Perez extended this logic: a supervisee’s ownership interest does not allow probation officers to treat a tenant’s home as searchable “property” under the supervisee’s search condition.
  • Smith v. City of Santa Clara and United States v. Harden: Discussed (in a footnote) to distinguish cohabitant cases from landlord-tenant cases. The court rejected importing a “assumption of risk” rationale (cohabiting with a supervisee) into a tenant’s relationship with a probationer-landlord.

E. Exclusionary rule in forfeiture

  • One 1958 Plymouth Sedan v. Pennsylvania and United States v. Taylor: Anchored the proposition that the Fourth Amendment and exclusionary rule apply in civil forfeiture, so illegally seized evidence cannot sustain forfeiture.

3.2. Legal Reasoning

A. “Property” in a search condition does not swallow a tenant’s home rights

The Government’s first theory was textual: Perez’s conditions allowed warrantless searches of his “property,” Perez owned Teal Drive, so Teal Drive was searchable. The Fourth Circuit rejected this as a category error. A leased dwelling is still a “home” for Fourth Amendment purposes, and the tenant—not the landlord—holds the possessory privacy interest that Fourth Amendment doctrine protects.

The court did not treat this as a mere technicality; it grounded its conclusion in social and legal expectations reflected in consent doctrine. Under Chapman v. United States, a landlord’s property interest does not supply authority to admit police to a tenant’s home. By analogy, a supervisee-landlord’s diminished privacy expectation cannot be “exported” to erase a tenant’s normal privacy expectations. Thus, a supervision condition authorizing searches of the supervisee’s “property” cannot be read to authorize warrantless entry into a third party’s leased residence.

B. Probable cause is required to treat a third party’s home as a supervisee’s “residence” for probationary search purposes

The Government’s alternative theory was functional: officers believed Perez actually lived at Teal Drive, so they could conduct a probationary residence search. The district court applied a lower “reasonable suspicion” approach; the Fourth Circuit raised the threshold to probable cause when the home is “not known” to be the supervisee’s.

The court’s core reasoning was structural. In the third-party-home setting, the residence-status determination is effectively the only gatekeeping safeguard. Following the logic of United States v. Brinkley, a probable-cause requirement prevents third-party homes from becoming searchable based on rumors, stale information, or minimal corroboration. The court also stressed that the burden on law enforcement is modest: supervision systems already track addresses, and the key requirement is simply adequate proof that the supervisee truly resides at the targeted home.

C. Application: the Government did not show probable cause Perez lived at Teal Drive

On the record presented, the court found both the quantity and quality of information insufficient:

  • A confidential informant allegedly said Perez lived at Teal Drive, and probation officers claimed unspecified “investigative efforts” including surveillance—but the record contained no detail about the tip’s basis, reliability, or what surveillance showed, limiting the tip’s weight under the corroboration principles reflected in Alabama v. White.
  • Coleman stated she and her daughter had lived at Teal Drive for over a year and did not confirm Perez lived there.
  • Probation officers had conducted twelve monthly visits to Perez’s reported address at Lawndale Drive; Perez was present during visits and arrived there during the search, while officers remained with him there during the Teal Drive entry—facts the court treated as undermining the claim that Teal Drive was his actual residence at that time.
  • Prescription bottles with Perez’s name and Teal Drive address were discovered at Lawndale Drive, but (i) the officers planned to search Teal Drive before entering Lawndale Drive, and (ii) even if known, the Teal Drive address could be stale or administrative, given Perez previously lived there.

Because probable cause was not established, the warrantless probationary entry/search was unconstitutional; the resulting evidence was suppressible in the forfeiture case under One 1958 Plymouth Sedan v. Pennsylvania.

3.3. Impact

  • Fourth Circuit rule for probationary searches of third-party homes: Officers must have probable cause of residence before using a supervisee’s search condition to enter and search a home “not known” to be the supervisee’s. This aligns the Fourth Circuit with the Eighth and Ninth Circuits’ approach (United States v. Thabit; United States v. Grandberry) and extends United States v. Brinkley’s third-party home protection logic into supervision searches.
  • Landlord-supervisee conditions cannot be used as a backdoor warrant exception against tenants: Leasing arrangements now have explicit Fourth Circuit protection from being treated as searchable merely because the owner is under supervision and subject to “property” search clauses.
  • Operational consequences for probation offices and partnering police: Agencies must document and corroborate residence evidence (e.g., verified occupancy indicators, recent surveillance specifics, admissions, key possession patterns, consistent overnight presence) if they intend to search a location other than the supervisee’s verified address without a warrant.
  • Civil forfeiture vulnerability: Because suppression applies in forfeiture (One 1958 Plymouth Sedan v. Pennsylvania; United States v. Taylor), unconstitutional search steps can collapse an entire forfeiture case, as happened here (dismissal instructed).

4. Complex Concepts Simplified

  • Probable cause vs. reasonable suspicion: Reasonable suspicion is a lower standard—enough to suspect wrongdoing based on specific, articulable facts. Probable cause is higher—enough facts for a reasonable person to believe something is true (here, that Perez actually lived at Teal Drive at the time).
  • “Probationary search” / supervision search condition: A court can require a supervisee to submit to searches (sometimes warrantless). That reduces the supervisee’s privacy rights, but it does not automatically reduce everyone else’s rights.
  • Third-party rights: A “third party” here is someone not under supervision (Coleman). The court treated her home privacy as intact and requiring heightened protection.
  • Landlord-tenant Fourth Amendment principle: Renting a home gives the tenant the right to exclude others, including the landlord and, generally, police without a warrant. That is why a landlord’s consent—or a landlord’s supervision condition—cannot substitute for a warrant.
  • Exclusionary rule in forfeiture: If the government obtained evidence through an unconstitutional search, it cannot rely on that evidence to win forfeiture of property.

5. Conclusion

United States v. Perez establishes a clear Fourth Circuit safeguard for homes occupied by non-supervised individuals: probation and supervised-release search conditions cannot be leveraged to enter and search a third party’s home unless officers have probable cause that the supervisee actually resides there, and a supervisee’s ownership of a leased dwelling is not enough to treat it as searchable “property.” The decision strengthens the Fourth Amendment’s traditional protection of the home while preserving supervision searches within constitutionally defined limits—especially where third-party tenants would otherwise bear the cost of a supervisee-landlord’s diminished privacy.
