Materials cost about the same everywhere, so the difference is mostly pay. These are numbers to plan with, not quotes. Prices still change by neighborhood and contractor, so get two or three local bids. You can also see prices for all of Washington.

What Seattle permits say jobs cost

When someone files for a building permit, they write down what the job will cost. This table uses 4,970 home-sized permits issued in the last 12 months (City of Seattle Building Permits). It shows the median filed value (half of jobs listed less, half listed more) and the middle 50%, the range where the middle half of jobs fall. People often list less than the final price, so use these numbers as a check, not a quote. See every city on what projects actually cost.

Common questions

Is it expensive to renovate in Seattle?
A typical project in the Seattle area costs about 20% more than the U.S. average. Construction workers there earn $87,590 a year on average, 34% above the U.S. average of $65,360 (2025 U.S. government wage data). Labor is a big part of what most jobs cost, so local pay moves the price.
Why does Seattle cost more than average?
Materials cost about the same across the country. What changes the price is local pay. Of the 44 large metro areas we track, the Seattle area ranks 2 for construction pay, where number 1 pays the most.
Do these prices cover the whole Seattle area?
Yes. These prices are for the whole Seattle metro area, meaning the city and the towns around it. Quotes still change by neighborhood, contractor and the size of the job, so get two or three local bids. For a number that fits your project, use the calculator in any cost guide.
