Draft 2015 Mechanical and Fuel Gas Codes Available in September

DPD will soon be posting the 2015 International Mechanical Code and International Fuel Gas Code, both with Seattle Amendments, for public review and comment on our website. In late September DPD will also host a series of technical review sessions where participants will learn specific differences between the 2012 and 2015 versions of these codes.  Keep an eye out for these drafts and review sessions to be posted soon at www.seattle.gov/dpd/codesrules/changestocode/BuildingCodeUpdate/.

Code Correction Amendments for Public Review

DPD is responsible for the development and routine maintenance of the Land Use Code and related regulations. We periodically propose legislation to amend the Land Use Code (Title 23) and related land use regulations in the Seattle Municipal Code (in this case, Chapters 3.58, 25.05, 25.06, and 25.08) to clarify and improve the function of various provisions. Our proposed amendments are called “omnibus” amendments because we package a collection of amendments that are small scale, with a limited scope of impact.

On January 12 we released a public review draft of proposed omnibus legislation and a Director’s Report to make corrections to the Seattle Municipal Code.  We also completed an environment review of the proposed legislation per the State Environmental Policy Act (SEPA) on the same day. The amendments have been requested by community members, elected officials, and City staff.

The proposed legislation would:

  • Clarify regulations to be consistent with the City Council’s original intent
  • Provide consistency and predictability for neighbors and permit applicants
  • Correct inadvertent clerical errors and incorrect cross-references, and clarify existing Code language

We are taking public comments on our draft legislation until January 29.  After that we will continue to take comments until we send final recommendations to the Mayor for transmittal to the City Council.  We anticipate that the legislation will be ready for City Council’s consideration this spring or summer.
