Seattle’s builders are still paying a little more to get projects out of the ground, but the wild swings of the past few years look like they are finally calming down. Late last year, nonresidential construction costs in the city nudged higher, even as bidding and pricing started to feel more predictable to developers and contractors trying to pencil out 2026 work.
What the numbers say
According to Mortenson, tracked nonresidential construction costs in Seattle rose 0.30% in the fourth quarter of 2025. Nationally, the firm recorded a 1.05% jump over the same period, putting Seattle on the softer end of the spectrum.
The report notes that year-over-year cost escalation is still elevated, even as some supply-chain pressures ease and conditions show what the firm calls “improving resilience.” Mortenson’s regional data points to a flatter and more predictable pricing environment in the Pacific Northwest compared with several other major markets.
How Seattle compares
Local business outlets quickly seized on the gap between Seattle’s numbers and the national averages, characterizing the city’s trend as relatively mild. As the Puget Sound Business Journal reported, that flatter cost profile is giving owners a clearer view as they line up projects and budgets heading into 2026.
Developers pivot to lower-risk work
That growing predictability is already showing up in the kinds of deals that are moving forward. Developers are leaning into renovations, conversions and smaller projects where hard costs are easier to forecast and financing feels a little less nerve-racking.
Filings and local reporting highlight the RDA Building in the Chinatown-International District as one of the properties being repositioned, with owners trying to dial down both construction and financing risk. Conversion plans and broader developer activity in the neighborhood are outlined by CoStar.
Materials, labor and the fine print
The cost story is not uniformly rosy. According to Mortenson, metals and long-lead electrical equipment remain selective pressure points, even as trucking and warehousing costs begin to stabilize. It is a mixed picture that still leaves some scopes exposed to sudden price moves.
That combination, the report cautions, is likely to keep the market competitive and choosy about which projects actually break ground in 2026.
Permits and fees still matter
Even with materials behaving a bit better, city processes are still a major part of the pro forma. Permitting timelines and fee changes can easily eat up any predictability gains on the cost side.
Hoodline reported that the City of Seattle adjusted several construction and inspection fees in early January, changes that local contractors say will be baked into 2026 budgets as teams bid and underwrite work. Those construction and inspection fee changes included reactions from builders who are already recalibrating their numbers.
For now, the modest quarterly uptick looks more like a reset than a return to the rapid escalation that rattled the industry in recent years. Builders, owners and lenders will be keeping a close eye on material prices, labor availability and permit timelines as they decide which projects to nudge from the drawing board into active construction this year.
