Firearm Storage Rules in Cambridge, Massachusetts

Firearm storage in Cambridge is governed at least by the statewide standard in MGL Chapter 140, Section 131L.^[1] A review of Cambridge's published municipal code and listed uncodified ordinances did not identify a separate local firearm-storage rule as of August 25, 2026. The City directs readers to its municipal code and advises contacting the City Clerk for official ordinance copies.^[2]

Statewide Storage Standard

Section 131L generally requires a firearm that is not carried by or under the control of its owner or another lawfully authorized user to be secured in a locked container or equipped with an engaged qualifying lock or safety device. The statute contains specific exceptions and penalty tiers, so the text should be checked for the facts at issue.

Limits of the Municipal Review

The online Cambridge code is a reference source, and recently adopted measures may not appear immediately. The City states that official ordinance copies are available from the City Clerk. A person relying on the absence of a local rule should confirm with the Clerk or qualified counsel, especially after a recent City Council action.
