Cambridge Firearms Storage Ordinance

Cambridge firearms storage requirements are governed primarily by the state standard under MGL Chapter 140, Section 131L^[1]. No specific Cambridge municipal ordinance imposing storage requirements beyond the state standard was identified in publicly accessible databases.

State Baseline: MGL Chapter 140, Section 131L

All firearms must be stored either in a locked container (unlockable only by combination, key, or similar means) or equipped with a tamper-resistant mechanical lock or safety device rendering the weapon inoperable by unauthorized persons. A weapon is not "stored" if carried by or under the control of the owner. Antique firearms (pre-1899) are exempt.

Penalties (as Amended by Chapter 135)

Chapter 135 of the Acts of 2024^[2], Sections 69-70, significantly increased the penalty structure:

• Non-large capacity firearm: Fine of $1,000 to $7,500 or imprisonment up to 1.5 years, or both
• Large capacity firearm or machine gun: Fine of $2,000 to $15,000 or imprisonment of 1.5 to 12 years, or both
• Non-large capacity weapon where person under 18 may have access: Fine of $2,500 to $15,000 or imprisonment of 1.5 to 12 years, or both

A violation constitutes evidence of wanton or reckless conduct if a person under 18 gained access and personal injury or death resulted.

Municipal Authority

Proposed House Bill H.3610 would have allowed municipalities to enact stricter storage laws, suggesting that municipalities generally cannot exceed state storage requirements without special authorization.
