Log Building Standards

The International Log Builders Association, founded in 1974 as the Canadian Log Builders Association, is a world-wide organization devoted to furthering the craft of log construction. The ILBA is a registered non-profit Society in Canada and the United States. The ILBA writes and distributes educational material on log construction to individuals, institutions, and the industry. The organization is dedicated to the advancement of Log Builders and to promoting the highest standards of the trade.

It is the responsibility of every builder to understand and to conform to the best practices of the trade. These are minimum Standards for residential, hand-crafted, interlocking, scribe fit log construction. Log Building Standards are revised by the ILBA Building Standards Committee. Changes to this edition were made in January, 2000.
