| A town, city or municipality may not adopt a residential |
building code or nonresidential building code other than the |
Maine Model Building Code after the effective date of this |
chapter. A town, city or municipality that adopts the Maine |
Model Building Code or the International Existing Building Code |
may adopt amendments to the code codes at any time, as long as |
such an amendment does not result in the adoption of all or a |
significant portion of any code other than the code codes adopted |
pursuant to this section. This section may not be construed to |
prevent a town, city or municipality from selectively adopting |
parts or portions of the Maine Model Building Code or from |
adopting a building rehabilitation code. A town, city or |
municipality that adopts the Maine Model Building Code shall also |
adopt the International Existing Building Code. |
