Census and NOAA figures for the city of Seattle in King County, not the metro, with a source for each.
The median home in the city of Seattle was built in 1976, older than the U.S. median of 1980 and older than the Washington median of 1985.1 About 53% of Seattle's housing units were built before 1980, close to the national share, and 21% since 2010.1 A large share of newer homes means many systems are still inside a warranty; checking that comes before any repair quote. Owner-occupied homes in Seattle are older than rentals: a median build year of 1955 against 1989.1 Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap.
Most housing units in Seattle are not detached houses: 51% are in buildings of five or more units and only 37% are detached single-family homes.1 With most units in multi-family buildings, condo and HOA approvals sit alongside the permit for interior work. Owners and renters are roughly balanced in Seattle, with 44% of occupied homes owner-occupied (64% statewide).1 The median owner-occupied home in Seattle is valued at $938,600 (ACS), above the Washington median of $564,600.1 Home values above the state median tend to support fuller scopes; the written scope should still separate must-do from nice-to-have.
