Sec. 15. 35-A MRSA §121, sub-§2, as enacted by PL 2003, c. 645, §6, is amended to read:

2. Model code. After the effective date of rules adopted pursuant to subsection 1, a municipality may not adopt a building energy code other than the model building energy code or an amended version of the model building energy code. For purposes of this subsection, "amended version of the model energy building code" means a version of the code that does not include certain parts or portions of the code or that creates new exemptions from its requirements but does not include a version of the code that includes modifications to any standard established in the code. Nothing in this section requires a municipality to adopt a building energy code. A municipality that has a building energy code in effect prior to the effective date of the rules may continue to keep that code, but if the municipality replaces its energy code it must adopt the model building energy code or an amended version of the model energy building code in accordance with this subsection.

Sec. 16. Changes to multifamily building standards; effective date. Those sections of this Act that amend or repeal portions of the Maine Revised Statutes, Title 10, section 1415-C take effect on January 1, 2006.
