What Do Seattle's "Zombie Towers" Actually Mean for Office Tenants?

For the downtown core, yes, and the number is real. The Seattle Times reported in July 2026 that nearly 37 percent of downtown Seattle office space sits empty, citing Cushman & Wakefield, and called it the worst downtown vacancy rate in the country. The same reporting put King County assessor value loss at $15 billion since 2020, a 46 percent decline, with about $128 million a year in foregone property tax. Downtown office rents are down 25 percent in inflation-adjusted terms since late 2019.

The number you quote depends on whose universe you are quoting. Kidder Mathews put the Seattle CBD at 34.9 percent vacancy in Q2 2026 and the Puget Sound region at 23.4 percent. Cushman & Wakefield measured Puget Sound at 28.6 percent the same quarter. JLL, reported by GeekWire, had regional vacancy at 23.9 percent. None of them is wrong. They count different buildings, different size minimums, and different geography.

Quote the provider and the quarter or you are not quoting anything. That habit alone separates a broker who gets believed from one who gets checked.

Because vacancy is a stock and leasing is a flow, and right now they are moving in opposite directions.

Savills counted 2.4 million square feet of Puget Sound office leasing in Q2 2026, the strongest quarter since early 2019, and the first back-to-back pair of 2 million square foot quarters since then. First half leasing hit 4.6 million square feet. Cushman & Wakefield logged 3.4 million square feet of year-to-date leasing in Q2 2026, up 62 percent year over year, with net absorption improving from negative 2.41 million square feet a year ago to negative 386,368 square feet. JLL, via GeekWire, recorded roughly 372,000 square feet of positive net absorption in Q2 2026, the first positive quarter in four years, with technology tenants taking 42.5 percent of leasing activity.

The recovery is also geographically lopsided. Kidder Mathews had East King County posting 248,731 square feet of positive Q2 2026 absorption while Seattle Close-In gave back 247,471 square feet in the same quarter, with regional net absorption at negative 46,836 square feet. The Eastside sits at 21.0 percent vacancy. The Seattle CBD sits at 34.9 percent.

That gap is the whole negotiation. One side of Lake Washington is tightening. The other is still absorbing a decade of overbuild and Amazon's footprint reshuffle.

That is a map, not an obituary. Read it building by building and it tells you exactly where an owner has to compete for your signature.

Three places it shows up. Face rent first: Savills put Seattle CBD asking rents at $48.24 per square foot in Q2 2026 against $62.34 in Bellevue CBD, and Kidder Mathews had Seattle CBD Class A quoting $40.29, down from $40.60 the prior quarter. Second, concessions. An owner facing five more years of carrying empty floors competes on free rent and improvement dollars because nothing else is left to compete on. Third, time. Kidder Mathews counted 4.72 million square feet of sublease space in Q2 2026, 11.7 percent of everything available. With that much standing inventory, a downtown tenant can run a full market process without the options evaporating mid-search. Eastside tenants no longer have that luxury.

The value collapse matters here, and not the way the headlines frame it. A building marked down 46 percent eventually gets a new owner with a new basis. The Real Deal reported in June 2026 that Blackstone agreed to sell the 943,600 square foot U.S. Bank Center to Spear Street Capital for roughly $280 million, against $612 million paid in 2019, a 54 percent decline and about $297 per square foot. My read: an owner at $297 a foot can sign economics that an owner at $650 a foot mathematically cannot. Some of the best tenant deals of this cycle will be signed in buildings that just traded.

The discount is easy to see. The delivery risk is not. Landlord distress is only a tenant win if the landlord can still write the TI check.

The debt picture is not hypothetical. Trepp reported overall CMBS delinquency at 7.35 percent in June 2026, down 20 basis points, with the office sector at 11.57 percent and still creeping up. KBRA's July 1, 2026 report had office generating the largest share of newly distressed loans in June, 46.8 percent, or $642.1 million. CRED iQ measured office distress at 17.1 percent across the top 25 U.S. metros as of May 2026, against 12.7 percent for all property types.

Six things I check before a letter of intent goes out on a distressed building.

Capital stack. Pull the deed and the recorded deed of trust. Identify the lender, the original loan amount, the maturity date, and whether the loan is securitized. A 2027 maturity on a building at 40 percent occupancy is a countdown clock.

Lender control. Find out whether the loan has transferred to special servicing or a receiver is in place. Ask the leasing team directly, in writing. In Seattle, The Real Deal reported in June 2025 that 19 of roughly 30 downtown buildings tied to Martin Selig had been placed under outside management or handed to lenders. That is the environment you are underwriting into.

TI funding. Ask how the allowance gets paid and by whom. If the answer routes through a servicer approval, treat that allowance as a hope rather than a term. Get it escrowed at signing, backed by a letter of credit, or converted into free rent you control.

Operating expense risk. A cash-strapped owner cuts security, janitorial, and elevator maintenance long before it misses a mortgage payment. Cap controllable operating expense growth, exclude capital items from the pass-through, and write in an audit right with teeth.

Non-disturbance. Get an SNDA signed by the lender before the lease, not "to be provided." Without it, a foreclosure can wipe out a below-market lease that took six months to negotiate.

Successor obligations. Confirm in writing that unfunded TI, free rent, and renewal options bind a successor owner. If title changes, your client should not be renegotiating from zero.

That the discount pool is shallower than 37 percent makes it look. The vacancy is concentrated in commodity buildings most tenants would not take at any price, and the space clients actually want is tightening even in the CBD. CBRE's Q2 2026 U.S. office figures put prime vacancy at 12.3 percent against a national rate of 18.3 percent, the largest quarterly national decline in more than a decade. Seattle follows the same physics: the trophy floors with committed institutional ownership are a much smaller market than the headline implies.

The second version of the bear case is the one I take seriously. JLL reported no new speculative office construction under way in the region. If absorption keeps compounding the way Q2 2026 went, the tenant who waits for maximum distress in 2027 may find the floors gone and the concessions trimmed. The leverage window is open. It is not frozen.

Casey Krueger, BrokerHQ. I run downtown Seattle and the Eastside as two different assignments right now, and I tell clients that in the first meeting.

Downtown, the play is patience plus structure. Run a genuine market process across eight to twelve buildings. Sort them by ownership quality before you sort them by rent, because the cheapest face rent in the CBD frequently comes from the building least able to deliver the space. Target two categories: institutions with committed capital, and buildings that recently traded at a reset basis. Then spend your negotiating capital on delivery certainty rather than on the last dollar of face rent. I would rather have $80 a foot of escrowed TI at $42 than $110 of promised TI at $38 from an owner in special servicing. One of those numbers is real.

On the Eastside, the play is speed. At 21.0 percent vacancy per Kidder Mathews with East King absorbing 248,731 square feet in Q2 2026 alone and nothing new delivering, quality blocks are thinning. Waiting there costs money.

The part most brokers skip is the hour of public-record work. Deed, deed of trust, maturity, servicer status. It costs you one hour and it changes which buildings make the tour list. I have watched tenants sign beautiful economics into buildings that could not fund a demising wall, and the client does not remember the rent number when their build-out is stalled in month seven.

The zombie tower story will keep running through 2026 as loans mature and buildings change hands. Read it as inventory intelligence. The tenants who win this window are the ones whose broker read the capital stack instead of the headline. Disclosure: I run BrokerHQ, which builds software for Seattle tenant-rep brokers, so I am not neutral on whether this work should be easier.
