Public Meeting for Seattle’s Permanent Floodplain Development Regulations

The City currently has interim Floodplain Development Regulations in effect through February 2022 so that the City’s floodplain map and development regulations are consistent with federal law. Here is a link to the Interim Floodplain Development Regulations. The Federal Emergency Management Agency (FEMA) required updates to maps and regulations based on the February 2020 updated floodplain map for King County. This map (called the Flood Insurance Rate Map) identifies properties that are at risk of flooding and is used to determine which properties are required to have flood insurance.

2018 Seattle Codes Effective as of March 15

The 2018 Seattle construction codes went into effect on March 15, 2021. Unless your project is vested to an earlier code, all new permit applications are required to use the 2018 version of the building, residential, existing building, mechanical, fuel gas, plumbing, elevator, and fire codes and the 2020 versions of the electrical and boiler codes. A summary of key changes can be found on the Project Documents page of SDCI’s 2018 Seattle Code Adoption webpage.

New Code Interpretation for Townhouse Unit Separation

SDCI published a new Code Interpretation R302.2 Townhouse Unit Separation on March 15, 2021. The purpose of the Code Interpretation is to clarify methods to provide separation between townhouse units designed to the 2018 Seattle Residential Code. Typically, the code requires a fire-resistance-rated wall assembly to provide continuous separation between units from foundation to roof. There are several conditions where separation is required to extend beyond this enclosed floor area.

New Effective Date for 2018 Seattle Construction Codes

The effective date for the 2018 Seattle construction codes is March 15, 2021. This effective date applies to the 2018 Seattle editions of the building, residential, existing building, mechanical, fuel gas, plumbing, electrical, boiler, elevator, and fire codes.  Applicants can submit complete permit applications using either the 2015 or the 2018 versions of the Seattle construction codes between the state’s implementation date of February 1, 2021 and Seattle’s implementation date of March 15, 2021. As of March 15, 2021, SDCI will only accept permit applications that use the 2018 codes.

2021 Fee Changes

The Seattle City Council recently adopted the 2021 budget, including legislation that implements SDCI fee changes in 2021. This year, SDCI did not implement an across-the-board increase in fees but instead was able to make adjustments decreasing several fees. On January 1, 2021, changes to electrical, refrigeration, and furnace fees will go into effect.

Seattle Floodplain Development Regulations Extension

The City of Seattle proposes to extend the interim Floodplain Development Regulations that took effect in August 2020 extended by Ordinance 126113. If the City Council does not adopt this legislation the interim regulations would expire on February 24, 2021. This legislation will extend the original interim regulations for 12 months so that the City’s floodplain mapping and development regulations will continue to be consistent with federal law. The City needs this additional time to prepare a proposal for permanent regulations that includes conducting necessary studies, consulting with federal and state agencies, and public outreach.

2018 Seattle Construction Code Adoption Delayed to March 2021

SDCI is in the process of updating Seattle’s construction codes to the 2018 versions of the building, residential, existing buildings, fire, electrical, mechanical, energy, fuel gas, elevator, boiler, and plumbing codes. SDCI was planning to adopt the 2018 edition of the codes effective July 1, 2020.  Due to several factors, including the impacts of Covid-19 and the Governor’s executive order, the effective date was delayed to Feb 1, 2021.   Adoption of Seattle’s 2018 suite of construction codes has been further delayed.  The revised effective date is March 15, 2021.   

Restrictions on Use of Easements in Lieu of Drainage and Wastewater Main Extensions

Projects can only use easements in lieu of extensions of public sewer drains IF they have SPU approval.   As of this notice, projects submitting for new preliminary applications will not be allowed to use an easement in lieu of an extension of the public sewer system unless an adjustment or exception is made by the General Manager of SPU. SPU protects existing and future assets and ratepayer resources by providing an orderly and predictable public system. Minimizing the length of privately-owned side sewers will better serve future residents of the property, as well as reduce the total life cycle costs of owning and maintaining them. It will also help protect ratepayers by reducing claims filed by residents due to issues with easements and long, privately-owned utility services.
