Seattle rents are usually quoted in dollars per square foot per year, which is almost impossible to compare with an actual invoice. So here are the numbers the other way round, straight from our catalogue: 137 available units across 8 buildings, of which 89 are private offices, asking anywhere from $130 to $38,550 a month.
Average office rent in Seattle
Private space in the listing asks $2.25 to $6.33 per ft² a month — about $27 to $76 per ft² a year. The single most common rate is $2.63 per ft² a month, and a typical unit rents for roughly $5,097 a month. The spread looks dramatic only because it covers everything from a 43 ft² furnished room to a 16,598 ft² floor plate in the same table.
Where the cheap end and the top end sit
The lowest per-foot rates belong to Qualtrics Tower at 1201 Second Avenue and to 450 Alaskan Way South, both opening at $2.25 per ft² a month. The ceiling is $6.33, reached at Columbia Tower (701 Fifth Avenue) and at the creative floors of 1455 Northwest Leary Way in Ballard. A tenant at the top of that range pays nearly three times the rate of a value floor a short walk away — for the identical square foot.
Office space for lease: what sizes are on the market
Units run from 43 to 16,598 ft², averaging 3,406 ft². About a quarter of the private offices are under 500 ft², which is the format most one- to six-person firms actually need. Large floor plates above 12,000 ft² are available in six of the eight buildings, priced between $31,175 and $38,550 a month.
Flexible formats price separately
Not every requirement justifies a lease. A coworking desk costs $385 a month, a meeting room books from $120, a business address with mail handling is $110, and a virtual office starts at $100. Those rates are flat across the buildings that offer them, so at that end of the market the address is effectively free — you pay for the service, not the postcode.
What this means for a tenant in 2026
Seattle continues to price at roughly half of what comparable Manhattan space commands, and the competition sits in the commodity towers rather than the trophy ones. That is where concessions show up: free months on longer terms, turnkey fit-outs, month-to-month serviced suites. Anchor your budget on $2.63 per ft² a month, treat anything above $3.50 as a view-and-address premium, and check the live Seattle office listings — every unit shows its floor, exact size and asking rent.
