United States and Canada construction class codes
Touchstone supports the construction codes listed in this topic for the United States and Canada. Each listed code is not necessarily supported for both countries.
Solar codes were added, only for the United States, in Touchstone 2025 (13.0).
Note: For information about supported codes and limitations for specific
models, refer to the model documentation available on the Client Portal.
