The Uniform Dwelling Code (UDC) is the statewide building code for one- and two-family dwellings built since June 1, 1980. The Industry Services Division provides consultation and education concerning UDC construction standards and inspection procedures. Building materials are evaluated for conformance with standards. UDC inspection and contractor credentials are administered. The UDC is enforced in all Wisconsin municipalities.

Caution – Do not use the Southern Pine design values in the new UDC Appendix A for sizing joists and rafters. They do not reflect the reduced values in the newly adopted 2015 National Design Specification for Wood Supplement. To obtain the correct values, go to http://www.awc.org/pdf/codes-standards/publications/nds/AWC-NDS2015-Supplement-ViewOnly-1411.pdf  and scroll to Table 4A. Those values may be increased 15% for repetitive joist or rafter use (due to load sharing by 3 or more members spaced 24” o.c. or less) and an additional 15% for rafter use (due to snow load duration increase).

 

It is suggested that you click on a PDF icon when using the UDC Appendix to properly view diagrams, tables and text.
