What are the search warrant requirements in Maryland?

Maryland's warrant procedure is at § 1-203 of the Criminal Procedure Article, with state constitutional protection under Declaration of Rights art. 26.

1. Constitutional Foundation

The Fourth Amendment is supplemented by Md. Decl. of Rights art. 26. Maryland courts generally interpret art. 26 in lockstep with the Fourth Amendment (Liichow v. State) but enforce it independently.

2. Probable Cause & Affidavit

Md. Code, Crim. Proc. § 1-203(a) requires a sworn written application stating facts establishing probable cause. The warrant must particularly describe the place and items. Maryland applies the Gates totality test. Anticipatory warrants are recognized.

3. Who Issues

Section 1-203(a) authorizes a "judge" — circuit court judges and District Court judges — within whose jurisdiction the property is located. The issuer must be neutral and detached.

4. Execution

Knock-and-announce is constitutionally required (Wilson v. Arkansas). Following 2021 reforms after high-profile incidents, no-knock warrants are limited in Maryland — they must be specifically authorized in the warrant upon a showing of imminent threat or destruction (codified amendments to § 1-203). Section 1-203(a)(5) requires execution within 15 days. Nighttime service requires specific authorization for good cause.

5. Scope & Plain View

Search is limited to areas where listed items could reasonably be hidden. Plain-view seizure is permitted when officers are lawfully present and incriminating nature is immediately apparent (Horton v. California).

6. Exceptions to the Warrant Requirement

Consent, search incident to arrest, exigent circumstances, automobile (Carroll), inventory, protective sweep, and Terry frisk.

7. Suppression

Maryland recognizes the Leon good-faith exception (Patterson v. State) and generally tracks federal exclusionary doctrine, including Hudson v. Michigan on knock-and-announce violations.
