OBC 2024 Partial Occupancy Requirements: A Guide for Developers in London, Ontario

Safety and Fire Protection Standards for Phased Occupancy

According to Article 1.3.3.7 of the 2024 Ontario Building Code (OBC), occupying a building before construction is fully complete requires strict adherence to fire safety protocols. This includes the installation of required fire extinguishers on all occupied storeys and ensuring that garbage rooms, chutes, and ancillary services are fully functional. Additionally, firefighting access routes and dedicated elevators for firefighter use must be tested and operational up to the level above the highest occupied floor.

Protecting Means of Egress: Covered Ways and Safety Measures

To safeguard occupants, a covered way must be installed over all means of egress and public access areas. These structures must maintain a minimum height of 2400 mm, be weather-tight, and be capable of supporting heavy snow or construction impact loads as determined by a professional engineer.

Engineering Reports and Municipal Indemnity

Partial occupancy is not permitted without a comprehensive site safety plan and written agreement with the municipality to assume risk. The OBC requires reports from professional engineers attesting to the safety of life and health, ensuring that ongoing construction—including heavy lifting, noise, dust, and vibrations—does not adversely affect the occupied portions of the building.

Separation of Services and Public Access

A critical requirement under Clause (8)(k) is the total separation of utilities. Occupied areas must have independent heat, water, and electricity systems from the construction zones. Furthermore, occupant access points, vehicle deliveries, and elevators must be completely isolated from construction staging and loading areas to prevent accidents and ensure comfort.
