IEBC Background
Encourage the use and re-use of existing buildings while requiring reasonable upgrades and improvements in code compliance.

3. 2006 IEBC Fundamentals
3/31/2017
WI IEBC History
Replaces S&B Existing Building Guidelines, Wisconsin Historic Code (Comm ch. 70) and IBC ch. 34, which share similarities with IEBC.
Provides a more predictable alternative than one or more petitions for variance
Note that there is no distinction between buildings originally approved under ICC suite or pre-ICC Wisconsin codes
Note that per s , WI Stats, local ordinances may not be anymore restrictive for historic building projects approved per this code

4. 2006 IEBC Fundamentals
3/31/2017
IEBC Approach
New work intended by the owner is generally regulated by the IBC, IMC, etc., but additional upgrades maybe triggered by the IEBC depending on the type and extent of the intended work.

s. Comm (1) Application
Does not apply to unchanged existing buildings which are instead subject to:
Per s. Comm 61.03(13) for post-1914 structures:
Buildings shall continue to comply with applicable State Building Code
Bleachers and grandstands shall comply with ICC Bleacher Standard – annual owner inspections and retroactive 4” guard infills
Or chs. Comm Buildings Constructed Prior to 1914 (previously titled, Existing Buildings Code)
And applicable fire prevention codes, ch. Comm 14 & IFC or NFPA-1

8. s. Comm 66.0101(2) Change of Use to a Public Building
2006 IEBC Fundamentals
3/31/2017
s. Comm (2) Change of Use to a Public Building
Change of Occupancy to a Public Building Occupancy from non-commercial use – comply with new construction requirements per IBC, rather than IEBC, except that archaic materials may continue to be used
Revised Comm (2)(b)2. to allow qualified historic buildings including 1&2 family dwellings to use the IEBC
May petition to use IEBC or alternative compliance for other non-commercial buildings
Also requires that initial tenant spaces plans following shell approval shall meet new construction requirements of IBC

9. 2006 IEBC Fundamentals
s. Comm Plan Submittal
3/31/2017
Required for new buildings, additions and alterations
Change of Use - There is NO requirement that a plan has to be submitted to gain an approval for a change in use. Submittal requirements exist only for the plans of the alteration work that is often desired or required with a change a use.
61.30(4) Minor Alterations - If the code official can understand the proposed project and agree that compliance can be achieved without having plans to work from, no submittal of plans is necessary - Document the decision!
