From: Building Inspector Stefan Nilsson
Agenda Item: Adoption of the 2006 International Mechanical Code
BACKGROUND & JUSTIFICATION:
September 13, 2007, the State of Alaska adopted the 2006 edition of the International Mechanical
Code (IMC). in order to maintain our Deferment Agreement with the State of Alaska, the City of
Seward is required to also adopt the 2406 IMC. These laws and regulations set the minimum
acceptable standard and variances below the standard will not be granted. In other words, the City of
Seward is required to adopt a code at least as restrictive as the State's adopted code.
The Ordinance includes revisions made by the State and also suggested local revisions. The State of
Alaska adopts amendments to modify the Code specific to the State of Alaska. These amendments
are highlighted with an asterisk to clearly illustrate for the public and Council which amendments
can not be changed or deleted. The asterisks will be removed prior to the Ordinance being codified.
The City of Seward also adopts amendments specific to Seward including modifications for
Seward's climatic, geographic and seismic conditions and local fees. The local suggested
modifications are not asterisked and can be modified by Council.
CONSISTENCY CHECKLIST:
Where applicable, this Ordinance is consistent with the Seward City Code, Charter, Comprehensive
Plans, Land Use Plans, Strategic Plan and City Council Rules of Procedures.
