This article provides an overview of changes for the 2015 Permanent Wood Foundation (PWF) Design
Specification—a publication intended to address structural design requirements of a wood foundation for
light-frame construction. The standard for designing wood foundations, most commonly used in residential
structures in the upper Midwest, has been updated to reflect reference to the 2015 National Design
Specification® (NDS®) for Wood Construction and 2015 Special Design Provisions for Wind and Seismic
(SDPWS). The 2015 PWF, 2015 NDS, and 2015 SDPWS are all adopted by reference in the 2015 International Building Code and the 2015 International Residential Code.
