Why Are Seattle Office Asking Rents Barely Moving While Vacancy Hits 28%?

A tenant looking at a renewal quote in 2026 sees an asking rent close to what it was a year ago and concludes the market has not moved much. The vacancy number says otherwise. Both things are true at once, and the space between them is exactly where a good tenant rep earns the fee.

Because asking rent and the actual deal are now two different numbers, and landlords work hard to keep the first one high.

Kidder Mathews reported Seattle Close-In office vacancy at 28.0 percent for the first quarter of 2026, up from 27.6 percent the quarter before and the highest in the region. Net absorption ran negative again at roughly negative 392,000 square feet for the quarter. Average asking rent across all classes was $35.20 per square foot, down 1.4 percent for the quarter and 5.2 percent over the year. A 5 percent face-rate decline against 28 percent vacancy is not what a balanced market produces. It is what a market produces when landlords defend the asking number on purpose.

There is a reason they defend it. The quoted rent feeds the building's appraised value, and that value backs the mortgage. Cutting face rents marks the asset down and can trip loan covenants. Handing a tenant six months of free rent and a fat improvement allowance costs the landlord real money too, but it does not show up in the headline number a lender or appraiser scans. So the give migrates to where it is least visible. The concession is the cut. The asking rent is the costume.

It means roughly one of every four square feet of competitive office space is sitting empty, and the landlord across the table knows you have options. That is leverage, and it is most of the reason to re-trade rather than roll.

Seattle did not get here in a dip. Vacancy has risen for sixteen consecutive quarters, since the fourth quarter of 2021, when it stood near 12 percent. Multi-tenant space over 10,000 square feet ended 2025 at 22.8 percent vacant under Kidder's current methodology. This is not a soft patch you wait out. It is the baseline you negotiate against, and it has been deepening for four straight years.

One caution on the number itself. Different research houses define the market differently, so you will see Seattle's downtown vacancy quoted anywhere from the high 20s to the mid 30s depending on whether the figure covers the broader Close-In market or only the central business district towers. Cushman & Wakefield put the downtown core above 36 percent earlier this year. Use the source that matches the submarket your client is actually in, and do not mix figures from two houses in the same negotiation.

In the three places that do not print on a listing: free rent, tenant improvement allowance, and term structure.

Free rent is the cleanest concession because it is pure landlord cost with no mark to the face rate. In a 28 percent market, multiple months per year of term is realistic on the right asset, not a stretch ask. Tenant improvement dollars are the second lever, and they are where a landlord competing for a scarce credit tenant will move furthest, because a built-out space is easier to keep leased. Term flexibility is the third: shorter terms, expansion and contraction rights, and early-termination options all carry real value and rarely touch the quoted rent.

The point for the tenant rep is that none of this surfaces if you anchor the negotiation on face rate. You have to price the whole package, then re-trade the parts the landlord will move on, which are the parts the appraiser never sees.

Mostly Close-In and the Eastside, less so the suburbs, and not at all in retail.

The Eastside has loosened sharply, from 13.8 percent vacancy to 21.6 percent across the recent window in Kidder's data, so Bellevue and Redmond tenants hold more leverage than they did a year ago even if the headline still trails Seattle. The southern and northern counties run lower and give less. Retail is the mirror image, tight enough that the landlord holds the cards, so a retail tenant should not expect office-style concessions. Match the play to the submarket. The leverage is real downtown and on the Eastside, thinner as you move out.

Treat the renewal like a relocation even when the client wants to stay. A landlord gives the most to a tenant who can credibly leave, and the only way to be credible is to actually price the alternatives. Pull two or three real competing options, build the full economic comparison including concessions, then take that package back to the incumbent landlord. The asking rent is your starting anchor, not your target. Target the free rent, the improvement allowance, and the term.

One honest caveat. In a market this distressed, the landlord's own balance sheet is now part of your client's risk, and the most desperate landlord offering the biggest concession may be the one least able to fund the improvement allowance it just promised. Vet the counterparty before you chase the richest paper deal, and write the protections into the lease. We covered how to read those distress signals and structure around them in a companion piece on landlord counterparty risk.

The honest counter-argument is that the worst may be passing. Kidder itself noted that the pace of vacancy increases has decelerated sharply from the 2020-to-2023 run, which can be the first sign of a floor. If landlords sense a bottom, the concession window starts to close, and the richest giveaways of this cycle may already be behind us on the best buildings. Flight to quality cuts the same way: a trophy tower with strong leasing will not give what a struggling Class B building three blocks away will.

That is a fair read, and it argues for moving now rather than waiting for a deeper bottom that may not come. But deceleration is not reversal. Vacancy still rose in the first quarter, absorption was still negative, and 28 percent is 28 percent whatever the second derivative is doing. The leverage is real today. It is not guaranteed to be real in two years, which is the case for re-trading this year's renewals hard rather than rolling them.

The gap between a flat asking rent and a 28 percent vacancy rate is the tenant rep's entire edge in 2026, and it is invisible to a client reading only the quoted number. Your job is to make the invisible part legible: price the full package, surface the concessions the listing hides, and re-trade against the parts the landlord will actually move on. Lead with the vacancy number, negotiate on the concession number, and protect the deal against the landlord's own balance sheet. That is the read this quarter's data supports.
