About Interbay

Interbay is a neighborhood in northwestern Seattle that occupies the valley between Queen Anne Hill to the east and Magnolia to the west, together with the filled-in areas of Smith Cove and Salmon Bay. It is bounded on the north by Salmon Bay and the Lake Washington Ship Canal, on the south by Smith Cove (an inlet of Elliott Bay), on the east by 15th Avenue West and Elliott Avenue West, and on the west by the BNSF Railway line.

The area was originally settled as "Boulevard" by Henry A. Smith and was renamed Interbay by the mid-1890s. Rail arrived early, and construction of the Lake Washington Ship Canal in the 1910s added roughly 150 acres of filled tideland. Interbay remains predominantly industrial and maritime in character, and residential uses occupy a comparatively small share of the neighborhood.

Housing & homes

Interbay's residential base is small relative to its industrial footprint, and much of the housing is concentrated along the neighborhood's eastern and northern edges near 15th Avenue West and West Dravus Street. In recent decades this corridor has seen newer multifamily construction, and the local inventory is weighted toward apartments, condominiums, and townhomes rather than detached single-family homes.

Older residential fabric survives at the margins, including the early 20th-century houses of the Fourteenth Avenue West group near Smith Cove. Buyers looking for traditional detached homes generally find larger concentrations on the adjacent slopes of Queen Anne Hill and Magnolia, which frame the valley on either side.

Local conditions to know

Interbay sits on low ground, and substantial portions of the neighborhood occupy artificial fill and reclaimed tideland at Smith Cove and Salmon Bay. Published seismic hazard work identifies Interbay as one of the Seattle districts with elevated liquefaction potential in a Seattle Fault Zone earthquake, a characteristic tied to that fill and to alluvial soils. Buyers should factor geotechnical and structural due diligence into their process, and both buyers and sellers should confirm a specific parcel's FEMA flood designation, since shoreline and filled-lowland sites can carry flood-zone considerations. Salmon Bay water levels are regulated by the Hiram M. Chittenden Locks.

Transit access is a defining feature. The Sound Transit Ballard Link Extension is planned to run through the corridor, with a planned elevated Interbay station above 15th Avenue West near West Dravus Street and a planned Smith Cove station near the Magnolia Bridge; Sound Transit has scheduled the extension to open in 2039, and station design alternatives were still being studied as of the most recent public materials. The neighborhood is also crossed by the Ballard Bridge and the Magnolia Bridge and by active BNSF freight rail.

Getting around & local texture

Interbay is anchored by working waterfront and maritime infrastructure. The Port of Seattle operates Fishermen's Terminal on Salmon Bay and Terminal 91 at Smith Cove, a 210-acre site used for cruise operations and vessel moorage. Expedia Group's headquarters occupies the former Amgen waterfront campus on Elliott Avenue. The BNSF Railway's Balmer Yard and its locomotive maintenance shops sit at the center of the valley.

Public amenities include the Interbay Golf Center just south of the Ballard Bridge, the Interbay P-Patch community garden, Interbay Stadium, and a Washington Army National Guard armory. The Elliott Bay Trail runs south through Smith Cove Park toward the downtown waterfront, and commercial activity clusters along 15th Avenue West near West Dravus Street. Interbay lies within the Seattle Public Schools district; Seattle Public Schools assigns homes to attendance-area schools by address, and Lawton Elementary is cited as the neighborhood's attendance-area elementary school. Confirm current boundaries with Seattle Public Schools for any specific address.

What buyers & sellers weigh in Interbay

The residential inventory skews toward condominiums, townhomes, and apartments rather than detached single-family homes.
The planned Ballard Link Extension (targeted for 2039) includes a planned Interbay station near 15th Avenue West and West Dravus; verify station siting and any construction impacts for a given property.

Proximity to Expedia Group's campus and the downtown waterfront trail shapes local commuting and demand patterns.

Location of Expedia Group's headquarters on the former Amgen Elliott Bay campus.
A planned Ballard Link light-rail corridor with a planned Interbay station is set to change access in the neighborhood.
