King County Commercial Real Estate Advisory
90-Day Advisory Outlook | Seattle • Bellevue • Redmond • South King County | Washington State
Executive Summary
King County’s Q4 2025 fundamentals show a bifurcated CRE market: office remains the clear laggard with very high vacancy in the Seattle core and sustained tenant leverage, while industrial and retail are closer to stabilizing tightness, though both face pockets of new supply and demand volatility tied to trade, logistics, and consumer spending. Multifamily is rebalancing: vacancy is elevated but stabilizing, King County still captures most regional absorption, and the under-construction pipeline is large enough to keep operator execution, including lease-up and retention, as the dominant 90-day determinant of NOI.
Over the next 90 days, the highest-conviction watch items are policy and infrastructure scheduling, not just quarterly fundamentals. The Washington State Legislature is expected to adjourn the 2026 session March 12, with a governor action deadline April 4. The Sound Transit cross-lake light-rail connection is scheduled to begin March 28. Washington’s Clean Buildings Performance Standard Tier 1 compliance deadline is June 1 for covered buildings over 220,000 square feet, directly relevant to large offices, hospitals, and big-box retail and industrial campuses.
Capital markets conditions as of March 10–11, 2026 are best summarized as cautiously thawing but still highly underwritten. The Federal Reserve held the federal funds target range at 3.5%–3.75% on January 28, 2026, and the Senior Loan Officer Opinion Survey indicates generally unchanged standards and stronger demand for CRE loans. That is supportive at the margin, but not a return to loose credit.
- Office owners and investors: treat leasing as the product, not a back-office function; lean into renewal capture and structured concessions, and underwrite conversion optionality more explicitly for aging inventory.
- Industrial owners and investors: protect occupancy via early renewals and targeted TI or abatement; reduce spec exposure; watch port volumes and trade policy sensitivity.
- Retail owners and investors: focus on necessity-based and service tenancy, be sober on discretionary exposure, and treat the April–August cruise season as a short-cycle demand tailwind for waterfront and visitor nodes.
- Multifamily operators and investors: manage vacancy with disciplined concession surgery, prioritize renewals and retention, and re-check construction competition weekly rather than quarterly.
- All stakeholders: pre-plan compliance and CapEx paths for Clean Buildings and track local zoning implementation calendars, especially Seattle Phase 2.
Market Metrics by Asset Class
Office
In Seattle close-in, vacancy ended 2025 at 27.6%, the highest in the region. Q4 net absorption was negative 20,142 square feet, and average asking rents for all office classes were about $35.71 per square foot. On the Eastside, including Bellevue and Redmond, vacancy rose to 21.5%. Q4 net absorption was positive 217,018 square feet, but the year remained negative. Asking rent was about $41.09 per square foot. A key Q4 delivery was Four106, a 485,000-square-foot project delivered 0% pre-leased, increasing near-term leasing competition. South King County vacancy declined to 20.2% with positive 11,089 square feet of Q4 absorption and asking rents around $27.35 per square foot.
For benchmark pricing and cap-rate context, Lee & Associates reports Q4 2025 Puget Sound office vacancy of 16.9%, average FSG asking rent of $38.11 per square foot, and an office cap-rate indicator of approximately 7.7%. CBRE notes early signs of stabilization with positive net absorption and an overall Puget Sound vacancy of 28.6%, with limited new pipeline relative to the size of the inventory.
Recent King County office signals include large Eastside leases in Bellevue and Redmond, reinforcing a flight-to-quality and renewal commitment trend. Reported office sales examples include Class B assets in Seattle and on the Eastside trading in roughly the $238 to $366 per square foot range, reinforcing that pricing dispersion is driven by tenancy, fitness-for-purpose, and redevelopment optionality.
The next 90 days remain tenant-advantaged. The real edge comes from renewal capture and controlling shadow vacancy. The March 28 cross-lake rail opening is more likely to affect touring velocity and location perception than to immediately change vacancy mathematically.
Industrial
In Seattle close-in, industrial vacancy was approximately 9.4%, with asking rates for blended office and warehouse product reported around $1.36 per square foot per month. One of the major vacancy drivers was a roughly 702,000-square-foot logistics facility delivered on port-related land with no leases at delivery. Southend, especially Kent Valley, carried approximately 122.1 million square feet of inventory, vacancy of about 7.9%, and average blended rents around $1.05 per square foot per month. Construction slowed to two projects totaling approximately 587,000 square feet under construction, reflecting a more cautious supply environment. Eastside industrial ended with vacancy around 5.8% and rents near $1.89 per square foot per month, though with negative absorption.
Lee’s Q4 2025 industrial indicators show regional vacancy of 9.3%, an average asking rate of $14.67 per square foot per year NNN, and a cap-rate indicator around 5.8%, with roughly 3.6 million square feet under construction. CBRE also flags improvement in quarterly absorption, but notes vacancy rose to 10.4% because of major deliveries.
Notable recent King County industrial transactions include a major Woodinville distribution center sale for $115.25 million and another large industrial trade in Burien for $67.2 million. Demand remains sensitive to port and trade conditions, with October 2025 container volumes reported down 14.4% year-over-year, making industrial leasing especially responsive to short-cycle logistics demand.
Retail
Kidder Mathews reports King County retail direct vacancy around 4.4% at year-end 2025, with the Seattle retail market around 4.0%, indicating a still-tight market despite softening. CBRE reports Puget Sound retail availability around 4.0%, Q4 net absorption of negative 588,000 square feet, and an average net asking rent of $24.46 per square foot. Lee’s Pacific Northwest retail benchmark suggests a retail cap-rate indicator around 6.3%, implying stable yields but still borrowing-cost-sensitive pricing.
A North King transaction example includes a multi-tenant retail center in Lake Forest Park trading for approximately $28.9 million. For the next 90 days, retail remains healthy where anchored by necessity and service tenancy, but discretionary exposure deserves careful underwriting.
Multifamily
Cushman & Wakefield reports King County multifamily inventory at 283,013 units, with 9,682 year-to-date deliveries, 13,091 units under construction, 9,008 units of YTD net absorption, vacancy around 8.0%, and average effective rent around $2,153 per unit. Lee’s multifamily benchmark for the broader Seattle MSA suggests vacancy near 7.4%, asking rent near $2,064 per unit, and cap-rate indicators around 5.0%.
Transaction evidence shows liquidity remains for scale assets. That said, the current pipeline means execution, lease-up, retention, and concession management will dominate spring and summer 2026 performance.
Land Development
Industrial land scarcity and redevelopment logic remain central to King County land value. The Puget Sound Regional Council industrial lands analysis suggests only a limited share of core industrial land remains vacant or potentially redevelopable, supporting a structural premium for well-located industrial sites. The City of Seattle’s One Seattle comprehensive plan update is now in effect, and 2026 Select Committee hearings on Phase 2 zoning implementation will influence land pricing, mixed-use feasibility, corridor density assumptions, and redevelopment optionality. In unincorporated areas, updated critical areas rules also create a real entitlement watchpoint.
Supply Pipeline and Near-Term Development Signals
Office under construction at the Puget Sound benchmark level remains active, but within King County the biggest near-term competitive effect comes from the Eastside’s major recent delivery, which adds to a vacancy profile already above 20%. Industrial construction remains significant at the regional level, though Southend spec starts have clearly slowed. Retail supply is still muted relative to industrial and multifamily. King County multifamily under construction, at 13,091 units, is large enough to influence vacancy and concessions during the next 90 days.
King County also publishes issued permits and new applications reports for unincorporated areas, which can be used to monitor permit valuation and project velocity. Because many of the county’s largest projects are in incorporated jurisdictions such as Seattle and Bellevue, a serious market strategy should pair county reports with city permit systems.
Demand Drivers and Economic Base
King County’s population is estimated at approximately 2.34 million as of July 1, 2024, preserving its role as the primary demand engine for housing, office employment, and consumer services in Puget Sound. The county unemployment rate was reported at 4.9% in December 2025. Major employer demand remains anchored by Amazon, Microsoft, Boeing, Starbucks, Costco, the University of Washington, and related corporate, advanced manufacturing, research, and healthcare clusters.
Industrial and logistics demand is also influenced by the Port of Seattle and the Northwest Seaport Alliance. Port-related economic activity remains a major regional support for warehouse and distribution demand, even while trade volumes remain volatile.
Financing Environment and Rate Sensitivity
The Federal Reserve held rates at 3.5%–3.75% on January 28, 2026. Upcoming FOMC meetings inside the advisory window are March 17–18 and April 28–29, both of which matter for rate volatility, debt lock timing, pricing guidance, and buyer-seller negotiation ranges. The January 2026 Senior Loan Officer Opinion Survey indicates generally unchanged standards and stronger demand for CRE loans, but debt is still selective. Stabilized cash flow, sponsor strength, rollover visibility, and reserves remain central to execution.
Baseline cap-rate markers used in this advisory are approximately 7.7% for office, 5.8% for industrial, 6.3% for retail, and 5.0% for multifamily, using Q4 2025 market-level indicators rather than promising any specific deal outcome.

| Asset Class | Q4 2025 Posture | 90-Day Owner Moves | 90-Day Investor Moves | 90-Day Occupier Moves | 90-Day Lender Moves |
|---|---|---|---|---|---|
| Office | Very high Seattle vacancy, Eastside still over 20%, tenant leverage persists. | Run renewal-first playbooks, structure concessions into longer WALE, prepare for large-building energy rules. | Underwrite realistic downtime and TI; favor assets with conversion or transit-node logic. | Press for abatements, TI, flexibility, and location trade-offs post-rail opening. | Use tight DSCR, rollover testing, and compliance reserves for large assets. |
| Industrial | Vacancy elevated vs prior cycle lows; construction slowing but new supply still matters. | Secure renewals early, use surgical concessions, upgrade functionality where justified. | Target infill logistics and durable distribution locations; stress-test trade volatility. | Lock favorable terms while vacancy pockets exist. | Prefer stabilized assets and strong sponsors with disciplined tenant concentration. |
| Retail | Vacancy still relatively tight, but net absorption has weakened. | Focus on necessity and service tenancy; monitor tenant credit. | Favor grocery-anchored and daily-needs centers. | Negotiate targeted concessions in softening nodes. | Underwrite rollover carefully, especially discretionary exposure. |
| Multifamily | Vacancy elevated but stable; pipeline remains significant. | Use precision concessions, prioritize renewals, track competing lease-ups weekly. | Stay disciplined on basis and near-term rent growth. | Use delivery-heavy submarkets to negotiate concessions. | Require lease-up detail, exit-cap stress tests, and reserve discipline. |
| Land Development | Zoning implementation and land scarcity drive value more than raw vacancy. | Advance entitlements with schedule certainty and realistic infrastructure assumptions. | Prioritize infill sites with actual adopted upside, not speculative zoning assumptions. | Expect scarcity premiums in stronger access corridors. | Demand stronger contingency budgets and permit timeline clarity. |
