ISANTA maintains an active role in the development of various standards and codes.

Model Building Codes

Most towns do not write their own building codes. Towns usually adopt one of the building codes written and maintained by the International Code Council (ICC).

The predominant codes used are the International Building Code (IBC) or International Residential Code (IRC). Some localities may still use the older BOCA, ICBO, and SBCCI codes, which were consolidated by ICC several years ago.

These building codes are often referred to as “model building codes” because towns “model” their building code after one of these codes. They may adopt one of the codes verbatim or they might make changes. The IBC and IRC are reissued every 3 years with ongoing reviews and necessary updates between versions. The current versions available from ICC are the 2015 IBC and the 2015 IRC.

The model building codes contain fastening schedules. Some schedules are for framing. Tables for shear walls and horizontal diaphragms are used by design professionals like architects and structural engineers when designing a wall or roof to resist or transfer forces such as those produced by wind or seismic activity. Other schedules tell how to fasten sheathing to roofs, walls, and floors.
