Trade Support Organization

CASBA offers trade support in several forms. We provide hands-on training to builders and contractors; provide information to assist homeowners in communication with building professionals; and assist builders, building officials, designers, and clients when natural building techniques, code, or nomenclature are proving difficult to navigate.

Support also includes:

  • The CASBA details book
  • Live database of natural building professionals
  • Permitting / Code interpretation assistance
  • Workparty / Workshop Training
  • Structural, fire, and thermal resistance data for straw assemblies
  • Member list and contacts
  • Fire Rebuild Toolkit

And we have a long list of additional resources that we are actively working to add (support on cost estimating, methods for streamlining construction, new design details, and more)
