New Code Interpretation for Fire Wall Continuity at Offsets

January 3, 2023

Fire walls are the most robust form of fire-rated assemblies in the Building Code and have strict rules for their construction and continuity. In Seattle, fire walls are being used more frequently for a variety of reasons, including: Fire walls are required for compartmentalization when building 6 stories of wood construction using the Seattle amendment to promote more affordable housing (SBC 510.10); and Fire walls are used to subdivide a building into separate “buildings,” either to change the occupancy designation or to separate new construction from existing.

New Zoning Name – Neighborhood Residential Zones

May 31, 2022

On December 15, 2021, Mayor Durkan signed Ordinance 126509, which changes the name of “Single Family” zones to “Neighborhood Residential” zones. Seattle’s Land Use Code and the official zoning maps divide the city geographically into zoning districts (e.g., single-family residential, multifamily residential, commercial, industrial, etc.). Ordinance 126509 applies the new zone name by dividing the neighborhood residential areas into four zones, based on pre-existing minimum required lot sizes: Single-family 9600 (SF 9600), Single-family 7200 (SF 7200), Single-family 5000 (SF 5000), and Residential Small Lot (RSL).

Revised Policy for Use of Fire Walls in Lieu of Substantial Alterations

April 5, 2022

Substantial alterations are a part of the Seattle Residential Code (SRC) that is applied when a large percentage of the house is being renovated or a large addition is being constructed; SRC Section R107.9. The requirements of substantial alterations are to update the house to the current code for major life safety items of fire, egress, and seismic. Substantial alterations may be required when an attached accessory dwelling unit (AADU) is created as an addition to an existing house. Traditionally, SDCI has given a break from substantial alterations when an AADU is being created in an existing house to support the housing need in Seattle, though this break has not been given when a new addition to a house is for an AADU. Recently, SDCI has revised the policy to allow fire wall construction in compliance with Seattle Building Code 706 to separate a new addition from an existing dwelling unit per SRC 107.5.

Energy Code Tips – New & Updated

December 1, 2021

Our new Tip 424, Heat Pump Water Heating for Commercial and Multifamily Buildings, has been posted on the SDCI Tips page. For permit applications filed beginning January 1, 2022, central domestic water heating systems in hotel and multifamily buildings must utilize heat pumps, rather than conventional gas or electric resistance systems. (In December, City Council will consider extending this requirement to include other commercial buildings with substantial water heating loads. That requirement, if approved, would take effect later in 2022.)

New Seattle Laws Impact Tenant Relocation Assistance License Process

October 29, 2021

Several recent changes to Seattle laws impact residential properties that require a Tenant Relocation License. The Right of First Refusal, SMC 7.24.030.J, requires owners to offer a lease renewal to existing tenants when their term lease is expiring unless there is just cause. To obtain just cause for development activity, you must obtain a Tenant Relocation License. Therefore, all properties that are tenant-occupied at the time of the permit application need to go through the Tenant Relocation Assistance Ordinance (TRAO) process regardless of whether the tenants have a term lease or are month-to-month. We highly recommend that you submit a service request for TRAO when you receive the notification that your project may require a license. If you wait until the end of the permitting process, your permits may be significantly delayed. You can submit a service request by calling (206) 615-0808.
