ICC Adds to Codes for Cob Construction, ‘Tiny Homes’

The International Code Council has added adoptable appendices in the current 2021 International Residential Code (IRC) pertaining to cob construction and “tiny homes,” the organization announced.

The appendices, according to the Washington, DC-based ICC, are aimed at providing explicit guidelines for builders, remodelers and local authorities in dealing with cob buildings and tiny homes.

Cob is an earthen material mix of clay-soil, straw and water that is placed into a wall in layers to create a monolithic wall. Cob buildings typically feature raised impermeable foundations and extended roof eaves to protect the walls from moisture and weather.

“Tiny homes” are most often less than 400 sq. ft., with some as small as 80 sq. ft. The units are typically constructed in a factory setting, and then transported to the building site and placed on a permanent foundation.

The International Code Council is the leading global source of model codes and standards and building safety solutions that include product evaluation, accreditation, technology, training, and certification. The Code Council’s codes, standards, and solutions are aimed at ensuring safe, affordable, and sustainable buildings worldwide. Additional information can be obtained by visiting www.iccsafe.org.
