1 2006 IEBC Fundamentals3/31/20172009 International Existing Buildings Code (IEBC) & Comm 66 Fundamentals & Revisions
2 2006 IEBC Fundamentals3/31/2017IEBC BackgroundEncourage the use and re-use of existing buildings while requiring reasonable upgrades and improvements in code compliance.
3 2006 IEBC Fundamentals3/31/2017WI IEBC HistoryReplaces 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 varianceNote that there is no distinction between buildings originally approved under ICC suite or pre-ICC Wisconsin codesNote that per s , WI Stats, local ordinances may not be anymore restrictive for historic building projects approved per this code
4 2006 IEBC Fundamentals3/31/2017IEBC ApproachNew 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.
5 IEBC Proportional Approach 2006 IEBC Fundamentals3/31/2017IEBC Proportional ApproachREQUIDCh. 6 Level 1 AlterationCh. 7 Level 2 Alteration3Ch. 8 Level 3 AlterationCh. 9 Change of UseUPGRADES21Alt. Lev.1Alt. Lev.2Alt. Lev. 3Change of UseTypes of Work
6 2006 IEBC Fundamentals3/31/2017s. Comm (1) ApplicationDoes 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 CodeBleachers and grandstands shall comply with ICC Bleacher Standard – annual owner inspections and retroactive 4” guard infillsOr chs. Comm Buildings Constructed Prior to 1914 (previously titled, Existing Buildings Code)And applicable fire prevention codes, ch. Comm 14 & IFC or NFPA-1
7 2007 ICC 300 Bleacher & Grandstand Standard Adopted per IBC 1028 Retroactive 4” bleacher guard infill at perimeter and between seats and footboards
8 s. Comm 66.0101(2) Change of Use to a Public Building 2006 IEBC Fundamentals3/31/2017s. Comm (2) Change of Use to a Public BuildingChange 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 usedRevised Comm (2)(b)2. to allow qualified historic buildings including 1&2 family dwellings to use the IEBCMay petition to use IEBC or alternative compliance for other non-commercial buildingsAlso requires that initial tenant spaces plans following shell approval shall meet new construction requirements of IBC
9 2006 IEBC Fundamentalss. Comm Plan Submittal3/31/2017Required for new buildings, additions and alterationsChange 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!
