What is the chimney code?

The chimney code is an aspect of the building code concerning the chimneys. Many nations follow the instructions set out in the International Building Act and the related International Residential Code by creating a chimney code, while some nations add specific regulations dealing with regional concern. Like other aspects of the Building Code, the chimney is not proprietary and is freely available to the public. It is intended for the use of suppliers, architects and other building experts to ensure that the structures meet the safety requirements set out in the Building Act. The chimney code is usually quite lengthy and gets into explicit details of the minimum requirements that must be met when creating a chimney. Specific regional concerns may include concerns about seismic activities could destabilize chimneys. The chimney code also determines various permits associated with the construction of chimneys and solves problems such as chimney size, easy access to maintenance, etc.

The chimney code for different structures and types of applications also varies. For example, a chimney connected to a cremation furnace must meet different standards than a chimney connected to a household fireplace. If code regulations differ for different types of structures, as it is not unusual, the code also clearly defines the types of the respective structures and the differences between them, so the suppliers can be certain that they use the most suitable part of the building code.

6 The inspector can identify problems that need to be repaired before using the chimney or before the structure can be cleaned for use. Chimney inspections are usually required due to chimney fires, extreme seismic activities and other events that could cause the chimney damage. Codes are also regularly updated, which explains why the chimney can go through the inspection for one year and the next failure.
