The state is in IECC Climate Zones 6 (south) and 7 (north). Wind Zone 1 with 130 mph ultimate design wind speed. Snow loads range 30-60 psf. Low seismic risk (SDC A-B). Wisconsin has a unique dual-code system: the UDC for residential and the Commercial Building Code for all other structures. DSPS provides statewide enforcement and licensing.
