Connecticut Fire Code: Key Requirements & Compliance Guide

The Connecticut Fire Code establishes minimum fire safety standards for buildings, structures, and premises across the state. It exists to protect lives, property, and first responders by enforcing fire prevention, detection, and suppression measures.

Connecticut adopts the NFPA 1 Fire Code (2021 edition) with state-specific amendments. Compliance is mandatory for all new construction, renovations, and existing buildings—regardless of occupancy type or size.

• Local Fire Marshals: Appointed in each municipality per CGS § 7-313a. Conduct inspections, issue permits, and enforce the code at the local level.
• Department of Administrative Services (DAS): Manages state-owned buildings and coordinates with the SFM.

Key Statutes & Codes

• Connecticut General Statutes (CGS) Title 29, Chapter 541: Fire Safety Code.
