2024 Ontario Building Code: Egress and Travel Distance Requirements for London Construction
Sarah's Expert Insight
OBC Compliance Specialist
"As your construction contractor in London, Ontario, we often see developers in Oakville and Muskoka overlook how dead-end corridor limits can drastically restrict suite layouts in multi-unit conversions. At empcontracting.ca Inc., we recommend integrating these travel distance calculations during the initial floor plan phase to avoid costly fire separation retrofits or the need for additional exits later in the build."
Understanding Egress and Exit Requirements in the 2024 OBC
Navigating the complexities of the Ontario Building Code (OBC) is essential for any successful renovation or new build. As empcontracting.ca Inc. your construction contractor in London, Ontario, we prioritize life safety through strict adherence to Section 9.9 regarding egress and travel distances.
Dead-End Public Corridors (Section 9.9.7.3)
The code strictly limits the length of dead-end corridors to ensure occupants can escape safely during an emergency. For residential (Group C) and business (Group D) occupancies, the maximum length is 6 meters. Retail (Group E) and industrial (Group F) spaces allow for up to 9 meters, provided occupancy loads stay within regulated limits.
Egress Door Requirements for Suites (Section 9.9.7.4)
In most commercial and multi-residential settings, a single exit door is insufficient if the suite exceeds specific size thresholds. You must provide at least two egress doors when:
- A Group D, E, or F suite exceeds 200 m².
- A Group C (Residential) suite exceeds 150 m².
- The travel distance from any point in the suite to the nearest door exceeds 25 meters.
Measuring Travel Distance and Required Exits (Section 9.9.8)
Travel distance is the total path an occupant must take to reach an exit. According to Section 9.9.8.2, most floor areas require at least two exits, spaced to ensure the travel distance does not exceed:
- 40 meters: Business and personal service occupancies.
- 45 meters: Sprinklered buildings across all occupancy types.
- 30 meters: All other non-sprinklered occupancies.
