Downtown Seattle Absorbed 300,000 SF in Q3, the First Positive Quarter Since 2021. Does That Change Which Buildings a Tenant Rep Should Tour?

CBRE's Q3 2026 Puget Sound office figures show vacancy of 27.9%, down 40 basis points, and availability of 28.2%, up 10 basis points. Net absorption was 514,000 SF for the quarter and 979,000 SF year to date. Average direct asking rent rebounded to $47.18 per SF full service gross after a dip in Q2. Leasing volume was roughly 1.5 million SF in the quarter and nearly 9.5 million SF over the trailing four quarters, up about 12% year over year.

By submarket, Downtown Seattle absorbed 300,000 SF, with the Seattle CBD at 197,000 SF. The Eastside lost 145,000 SF after three positive quarters.

Kidder Mathews measures a different geography. Its 3Q26 report puts Seattle Close-In vacancy at 27.7%, with 150,670 SF of positive absorption in the quarter but negative 459,019 SF year to date. The two firms define submarkets differently, so the numbers should not be netted against each other.

CBRE attributes the Eastside decline to GIX relocating approximately 96,000 SF in the Bel-Red Road corridor. That is the whole story at the submarket level: one tenant move accounts for roughly two thirds of the quarter's negative number.

The same submarket led the region in Q1 2026, when CBRE's report, as covered by Connect CRE, pointed to large-block tenants and AI-related tech companies, including OpenAI's 223,000 SF expansion at City Center Plaza in Bellevue. A submarket that leads in one quarter and trails in the next, on the strength of a handful of leases, is telling you how lumpy absorption is, not how any individual building is doing.

Not by much, and not evenly. Vacancy is 27.9% regionally. TenantBase's Seattle Q3 page lists Seattle CBD vacancy at 37.6% in its submarket data and 35.4% in its FAQ, so the honest reading is the mid-30s, which is still more than one square foot in three sitting empty. A positive quarter downtown after years of negative ones is a change in direction. It is not yet a change in who holds the pen on a specific floor.

Asking rent moving back up to $47.18 tells you landlords are testing price. Whether a particular landlord can hold it depends on that building's availability, its sublease competition and its debt, none of which appear in a quarterly figure.

Four questions turn a submarket number into a tour list.

Who absorbed the space? If a quarter's gain came from one or two large leases, the buildings that signed them may have less to offer, while the rest of the submarket looks the same as before.

Who is moving out and when? A building that gained a tenant this quarter can lose one next year. Lease expirations and announced relocations matter more than last quarter's total.

What is on the sublease market in the same building? Sublease space competes with the landlord's own availability and usually sets the real price floor for short-term deals.

What does the landlord need? A landlord with a near-term maturity behaves differently from one with a full rent roll, and public records often show which is which.

Each of those answers sits in a different place: the lease record, the building's tenant list, the sublease listings, the ownership and loan history. That is the data work a tenant rep repeats before every tour book.

Market-level numbers do matter. Four straight quarters of positive absorption and a rebound in asking rent are the reasons a tenant who waits may pay more later, and CBRE's trailing leasing volume of nearly 9.5 million SF says deals are getting done. A rep who ignores the trend and treats every building as an isolated case will mis-time advice about when to start a search.

There is also a data limit. The CBRE figures here come from a public summary page, not the full report, and the submarket vacancy figures on the TenantBase page are inconsistent with each other. Quarterly summaries are good for direction and poor for specifics, which is the argument for building-level checks, not against reading the quarter.

Pick the two buildings you expect to show most often in the next month. For each, write down who signed, who is leaving, what is on sublease and what the landlord's debt picture looks like, with a source and a date next to each line. If any line takes more than a few minutes to fill, that is the part of your process a data layer has to replace first.
