Commercial Buildings

​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.

Important Update: Automatic Sprinkler Systems and Fire Resistance Requirements

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).

Lighting Plan Submittals No Longer Required

Effective immediately, the Division of Industry Services Commercial Building Program will no longer require the submittal of either emergency egress lighting plans or lighting energy conservation plans to our agency. Instead, the following are the revised expectations:

Emergency Egress Lighting - Building designers shall provide at the project site an egress plan showing where exit lights and emergency egress lighting will be required for new buildings, additions and alterations that create new egress paths. Effective July 1, 2012, this egress plan shall be included with the building plan submittal to our agency. In addition to the egress plan at the jobsite, there shall be emergency lighting cut-sheets, calculations or other means to show compliance of the installed fixtures. Local inspectors may request additional information.

Energy Conservation – Building designers, electrical designers or electrical contractors shall provide fixture layouts, fixture cut-sheet, energy calculations or other documentation at the project site.

These changes are the result of observed, improved compliance in lighting designs and installation since we instituted a temporary enforcement emphasis several years ago. We appreciate the efforts of designers, contractors and code officials to allow these changes. These changes will allow our agency to re-order our priorities as building plan submittals increase this year.

Commercial Building Code

COMcheck is Federal Department of Energy (DOE) software approved in Wisconsin for demonstrating compliance with commercial building envelope requirements and interior & exterior general lighting requirements ONLY (HVAC portions of the program are not acceptable). COMcheck can be used for commercial buildings or high-rise (>3 stories) multi-family buildings. [Within COMcheck, a user is required to choose the code option of "2009 IECC" unless 2009 IECC section 501.2 is applied which would then allow the application of ASHRAE 90.1-2007, in which case the option "90.1 (2007) Standard" must be used.]

Commercial Building Code Requirements for Low-Rise Multi-Family Residential Buildings

REScheck, another software application from DOE, is now used for demonstrating building envelope compliance for low-rise multi-family (3 dwellings or more, 3 stories or less above grade). (Within REScheck, a user is required to choose the code option of "2009 IECC" as the code type to demonstrate building envelope compliance.)

Building Materials/Product Approval

Building Materials Evaluation, under the product approval system as outlined in SPS 361.50. Product approval is generally voluntary. If a product meets the applicable codes and standards, then no further approval is necessary. If an alternative method of compliance is desired, then a petition for variance for a specific project or a product approval for various projects are options. If a national evaluation service such as ICC-ES has approved a product under a code or standard that we have adopted without relevant Wisconsin amendment, then we will generally accept that approval in lieu of a Wisconsin approval.

Wisconsin product approvals are typically valid for five years unless there is a relevant code change. During the approval period, the product approval may be included with individual project submittals and used for the term of the project approval, which may extend past the product approval term. Product approvals are listed on this website for the term of their approval. Contact our agency if a copy of an expired approval is needed.
