What are the minimum code requirements for a residential hallway?
Sunday, March 20, 2022
Here are the minimum code requirements for a residential hallway:
• Minimum width of a hallway is 3-feet (IRC R311.6).
• A receptacle outlet is only required when a hallway is 10-feet or longer, and just one is necessary even if hallway is much longer (IRC E3901.10).
• At least one switch-controlled lighting outlet (lighting fixture) required in every hallway, except that remote, central, or automatic light controls may be used as an alternative (IRC E3903.3).
• Minimum ceiling height of a hallway is 6-feet 8-inches (IRC R305.1.1).
• A smoke detector-alarm must be installed in every hallway providing access to a sleeping room (bedroom) (IRC AM104.3).
These requirements are based on the International Residential Code (IRC), and similar National Electrical Code (NEC) standards. Other codes and local jurisdiction amendments may be different. Also see Frequently Asked Questions (FAQ) about Minimum Code Requirements
