The 2006 editions of The Michigan Building Code, Michigan Residential Code and The Michigan Rehabilitation Code for Existing Buildings will take effect On August 1, 2008.

A change to the 2006 International Building Code deleted text which referenced the International Existing Building Code. This change eliminated the use of the IEBC as an alternative. The State of Michigan adopted the IEBC with its own amendments, thereby allowing it to be used as an alternative.

The State will have a limited number of copies of the new codes available for pick-up at DLEG’s offices in Okemos. They will not ship books. To order books through The International Code Council go to - 2006 Michigan Codes - to fill out an order. The State’s prices for the codes are the same as ICC’s member pricing.

Fred Bear writes: I was told by my inspector that the code doesn't allow "greenboard on a ceiling". Is this true?

Answer: Section 2509.3 of the 2006 IBC states 1/2 thick water-resistant gyp backing board can be used if the framing is 12" o.c. or less. 5/8" w-r-g backing board can be used on framing 16" o.c. or less. I must note this section only refers to "showers and water closets" and is referring to "backerboard" which I interpet as being used for tile or other like finishes. Back in the days of The BOCA model code, we did not allow w-r-g on ceilings by referring back to the individual gypsum manufacturer's written installation instructions. If you are planning on using it for a finish surface, I would refer to the manufacturer for their input.

SIde note: A change in 2006 IBC does not allow w-r-g backer board to be used as a base for wall tile in tub and shower areas and wall and ceiling panels in shower areas.
