Overview

For residential properties, Jefferson adopted the Wisconsin state building code with amendments, including an amendment that makes the code applicable to all work except minor repairs.  See Jefferson Code, Ch. 120, § 120-1 and § 120-5.

 

For commercial properties, Jefferson doesn't expressly say that it adopts the Wisconsin Commercial Building Codes, but it says that the "Plans for buildings required to comply with the State Building Code shall bear a stamp of approval from the Building/Zoning Inspector." See Jefferson Code, Ch. 120, § 120-1(C) and (I) (note that the Jefferson code refers to Ch. Comm 21-25 [applying to the dwelling code], which have been renumbered by the State to SPS 361, etc.).

 

Wisconsin adopts its very own residential building code by regulation.  See Wis. Adm. Code § SPS 320 (accessed 11/11/2013).  In other words, it has not adopted the IRC.  The Wisconsin code is a statewide code that applies to new construction, but allows local jurisdictions to adopt the code, extend it to existing buildings, and add requirements.  

 

Wisconsin adopted the 2009 IBC with amendments. See Wis. Adm. Code § SPS 361.05 (accessed 11/15/2013).  Wisconsin amends its commercial code by Administrative Code.  See Wis. Adm. Code § SPS 361, Administration and Enforcement;  Wis. Adm. Code § SPS 362, Building and Structures.

 

Authority for the state adoptions is found in statute. See Wis. Stat. Ch. 101.
