Plan Review Submittal Checklists


The Division of Industry Services reviews plans for public buildings and places of employment prior to construction for compliance with the state statutes and building codes and sets standards for energy efficiency and heating, ventilating and air conditioning systems. This includes multifamily buildings.

The division cooperates with local certified municipalities which provide plan review and inspection services for certain types of buildings. Inspection certifications are administered by Industry Services. Building materials are evaluated for conformance with standards. To become a local certified municipality, please visit our resources page.

Recent Announcements:

The Department of Safety and Professional Services-Division of Industry Services wishes to inform you on the status of the SPS 361-366 Commercial Code Package.  At this time, the proposed code package will not become effective by September 1, 2017.  While we are working towards a timeline for the code package to be finalized and released, a formal opinion has been requested from the State Attorney General’s office on a provision of code.  The Attorney General’s Office opinion will assist us in formulating portions of the code package.  As information becomes available, we will provide further updates.


The Department of Safety and Professional Services has been engaged in rulemaking to update Wis. Admin. Code chapters 361 to 366, the Wisconsin Commercial Code.  As part of this process, a review of the current fire sprinkler rules for multifamily dwellings was completed and feedback from stakeholders received. Stakeholder feedback called into question the enforceability of current fire sprinkler rules due to them being potentially more restrictive than allowed by statute. The Department takes these concerns seriously and has requested a formal attorney general’s opinion. For additional questions, please contact Chris Joch 608-267-9152.


SPS 364.0403 What ventilation requirements are to be met for a boat or other 'off-highway' vehicle storage area? 

Answer:  The Department's code has provisions that apply when a use does not fit entirely within one of the listed occupancies in either the IBC or IMC.  The Department has specifically modified IMC 403.3 to address this.  Ventilation rates for occupancies not represented in SPS Table 364.0403 shall be determined by using the most similar occupancy in the table as based on SPS 364.0403(5)(a).   The storage of a boat is more similar to storage of a vehicle than it is to general warehouse storage.  Additionally, when one rule prescribes a general requirement and a different rule a more specific requirement on the same subject, the more specific rule shall govern per SPS 361.03(3)(c).  Either of the occupancy classifications listed in SPS Table 364.0403  and IMC 403.3 could potentially relate to the storage of boats, however enclosed parking structure is a more specific designation.  The guidelines present in both 364.0403(5)(a)2.d. and 361.03(3)(c) support requiring boat or other 'off-highway' vehicle storage to comply with the exhaust requirements of an enclosed parking garage.

Uniform Building Code Update

2013 Act 270 establishes a uniform commercial building code in Wisconsin, while allowing municipalities to grandfather fire detection, prevention, and suppression ordinances that relate to the construction, alteration, or addition to a public building or building that is a place of employment. An ordinance that is grandfathered has passed the requirements laid out by the Legislature in Wisconsin Statute §101.02(7r)(b).
