International Existing Building Code
A large number of existing buildings do not comply with current building code provisions for new construction and in many cases, may not comply with the building code adopted at time of original construction.
Upgrading buildings to current building code for new construction is an option, however, can sometimes be cost prohibitive. Another option to consider, is evaluation of the building under the International Existing Building Code (IEBC). The intent of this code is to provide more flexibility to permit the use of alternative approaches in order to rehabilitate existing buildings, while still maintaining a reasonable level of safety. The IEBC code pertains to repairs, alterations, change of occupancy, additions and relocation of existing buildings. There are chapters on historic buildings and relocated buildings as well.
The IEBC has three (3) options for consideration:
Option 1: The Prescriptive Compliance Method (specified in Chapter 4)
Option 2: The Work Area Compliance Method (specified in Chapters 5-13)
Option 3: The Performance Compliance Method (specified in Chapter 14)
Each option has its own advantages and disadvantages and the designer needs to work closely with the building owner for a desired path forward. One option must be chosen for the design to then be submitted for building permit application.

Locking Access Port Caps for Refrigeration Piping
The International Mechanical Code requires locking access port caps for refrigeration piping. This provision was added into the code to deter a relatively new method of substance abuse where individuals intentionally inhale refrigerant gases for the intoxicating effect. Inhalant abuse is very dangerous, and it can result in sickness or death. Locking access port caps help prevent such abuse by making it difficult for individuals to tamper with or remove these caps without a special tool or key. The special caps also make it harder for individuals to tamper with the refrigerant levels in the system.
More recent published code editions have added an exception to exclude this code provision for equipment located in a controlled area, such as on a roof with a locking access hatch or behind locked fencing.
City of Boise Mechanical Inspectors will be enhancing inspection emphasis on verifying these locking access port caps are installed on all new equipment and replacement equipment when not installed in a controlled area.
