Notes: All electrical wiring, installations, equipment and materials used in the construction of dwellings are required to comply with the requirements of the Wisconsin Administrative Electrical Code.

The State commercial building code applies to all commercial buildings (public buildings and places of employment) with few limited exceptions. Plan review, enforcement and inspection provisions apply to most commercial buildings (public buildings and places of employment) with exceptions for some smaller buildings. Many plan reviews and inspections are conducted by local officials that are certified by the State to conduct those enforcement activities on their behalf. The State Uniform Dwelling Code applies to all one- and two-family dwellings. The State codes are uniform (mini/maxi) codes with strict limitations on municipal authority to have in place differing provisions. There are limited state inspectors for buildings. Most inspection is by the local officials.
