The typical Washington home is worth about $501,000 — see Washington home prices by city.

What drives construction costs in Washington

The state index reflects local labor rates, material delivery costs, and code requirements — Washington is among the most expensive states to build in, which pushes replacement costs well above most market expectations. Within the state, metro areas cost more than rural counties, hillside and coastal lots add site work, and post-disaster demand can lift prices 20% or more for a year.
