Common Examples

Home Entry for Arrest
William Williams is suspected of a serious crime. Officers arrive at his home with probable cause but no arrest warrant. They hear sounds indicating Williams is destroying evidence inside and enter immediately to prevent loss of that evidence. The entry is upheld because the risk of evidence destruction supplies the required exigency.
Minor Offense Weighs Against Exigency
Willow Walker is suspected of a low-level regulatory violation carrying only a small fine. Officers follow her to her condominium and enter without a warrant after seeing her through a window. The court suppresses the evidence because the minor nature of the offense makes it unreasonable to forgo obtaining a warrant.

Hot Pursuit into Home
Whitney Washington flees into her home after officers see her commit a violent felony. Officers follow and enter without a warrant to complete the arrest. The entry is lawful because hot pursuit supplies the exigent circumstance permitting warrantless home entry.
Coolidge v. New Hampshire403 U.S. 443 (1971)
Emergency Aid to Occupant

Chimel v. California395 U.S. 752 (1969)
Homicide Scene Limits
Wanda Williams is found dead in her apartment. Officers enter without a warrant and conduct only a brief sweep for other victims or suspects. Further evidence gathering is suppressed because the homicide alone does not justify a full warrantless search once the exigency ends.

Common questions
Frequently Asked
3
When does the gravity of the offense affect a finding of exigent circumstances?+
A minor offense punishable only by a small fine weighs strongly against finding exigent circumstances that would justify a warrantless home entry. Officers must show a compelling immediate need that makes obtaining a warrant impracticable, and low offense gravity cuts against that showing.
May officers temporarily restrict a resident's access to the home while seeking a warrant?+
Officers who have probable cause and are diligently pursuing a warrant may briefly prevent a resident from reentering unaccompanied to preserve evidence. The restriction must be modest in scope and duration and closely tied to the need to prevent destruction of evidence.
Does an overnight guest have standing to challenge a home search?+
An overnight guest who stays in a home with permission, keeps personal belongings there, and uses the space as a residence has a reasonable expectation of privacy and may contest a warrantless search of that home.
