BCAB #1498

Re: Door Hardware, Clause 1.1.2.1.(1)(k), Sentence 3.3.1.12.(3)

Project Description

This appeal involves the installation of additional hardware, for security reasons, on access to exit doors in an existing building of Group D occupancy.

Reason for Appeal

Clause 1.1.2.1.(1)(k) states that the code applies to "... the installation of ... equipment regulated by this Code." Sentence 3.3.1.12.(3) requires that door hardware "shall be operable by one hand and the door shall be openable with not more than one releasing operation."

Appellant's Position

The appellant contends that the additional hardware requested by the client must comply with the current code (1998 BC Building Code). The thumb latch deadbolts with which the client wishes to install on three office doors would be in addition to the existing lever handle passage sets and would not comply with Sentence 3.3.1.12.(3). An interconnected single motion lock set should be installed to replace the existing passage set.

Building Official's Position

The building official maintains that the installation of a thumb latch deadbolt is a relatively minor alteration and permits are not required. The building official is prepared to allow hardware that contravenes the current code in an existing building, provided it does not lessen the existing level of safety and it seems "reasonable."

Appeal Board Decision #1498

It is the determination of the Board that new hardware installed in addition to or to replace existing door hardware must comply with the current code. Alternate installations must meet the requirements of Section 2.5, Equivalents.
