QLD: Can strata schemes lock fire escape doors to improve security?

Question: Can a body corporate lock fire escape doors to prevent access to all floors?

We live in a 15 storey apartment building. Our fire escape doors do not lock from the inside, so once someone enters the fire stairs, they can access all floors. Can the body corporate lock these doors from the inside to improve security? What requirements apply for fire egress and safety?

Answer: The National Construction Code does permit one-way locking systems.

Under the National Construction Code (NCC), fire escape and stairwell doors must allow occupants to enter the stairwell from each floor at all times to ensure safe egress during an emergency. As a result, these doors cannot be locked in a way that restricts access to the stairwell.

However, the NCC does permit one-way locking systems. These systems prevent access from the stairwell into residential floors, while still allowing occupants to enter the stairwell from each level. This approach improves building security without compromising life safety or code compliance. Additionally, stairwell re-entry is a legislated requirement under the NCC.

A re-entry from the stairwell must be provided every 4th floor, allowing occupants to exit the stairwell back into the building if required during an emergency.

Any changes to fire escape door hardware must comply with the NCC and be approved to ensure ongoing compliance with fire and life safety provisions.
