1. What Is an Inventory Search?

An inventory search occurs when law enforcement, after lawfully impounding a vehicle, opens and documents its contents—not to find evidence, but to safeguard the owner’s property and protect the police department from liability.

Courts treat this as an administrative procedure, not a criminal investigation. That means no probable cause or warrant is required if strict legal conditions are met.

2. When Is an Inventory Search Lawful in Maryland?

To be legal, two conditions must be satisfied:

Lawful Impoundment
- The vehicle must be impounded for lawful reasons—such as arrest, traffic violations, or public safety hazards.
Following Standardized Police Procedures
- Officers must follow a written department policy that outlines how and where inventory searches are conducted.
- The search can’t be arbitrary or a pretext for an unrelated investigation.

3. Legal Foundations

Court rulings such as South Dakota v. Opperman and Cady v. Dombrowski affirm that inventory searches are reasonable under the Fourth Amendment when:

The vehicle is in lawful custody.
The search is done according to established policy.
The purpose is administrative, not investigative.

Maryland courts apply the same principles—lawful custody + standardized procedure are key.
