The following sections of Chapter 11 of the 2021 Edition of the International Fire Code, as adopted by BMC 17.20.010, are hereby amended as follows:

Section 1103.2 Emergency responder radio coverage in existing buildings. Buildings constructed prior to the implementation date of this code shall not be required to comply with the emergency responder radio coverage provisions except as follows:

1. Whenever an existing wired communication system cannot be repaired or is being replaced.

2. Buildings meeting any of the criteria listed in BMC 17.20 Section 510.1 which are proposing a change of use or occupancy type, an addition of any size, or a remodel involving more than 50% of the building’s total floor area.

3. When buildings, classes of buildings, or specific occupancies do not have minimum radio coverage signal strength as identified in BMC 17.20 Section 510.4.1 and the Fire Chief or Police Chief determines that lack of minimum signal strength poses an undue risk to emergency responders that cannot be reasonably mitigated by other means.
