Building specs

The Four Seasons Private Residences Seattle were developed by Nitze-Stagen & Co. and delivered in 2008 as part of the Four Seasons Hotel Seattle mixed-use complex at 99 Union Street. At 36 residences, it is the smallest unit count of any full-amenity luxury high-rise in Seattle — a supply constraint that is structural and permanent. The building sits directly above the Seattle waterfront promenade.

View orientation

The most complete Elliott Bay panorama of any Seattle residential address.

The Four Seasons Residences sit directly above the Seattle waterfront. There is no intervening building between the upper floors and Elliott Bay — the western and southern view corridors are unobstructed from water to horizon. This is a physical reality of the building's position that no Belltown tower, however tall, can replicate.

West / Southwest

Elliott Bay, Olympic Mountains, Puget Sound, ferry traffic, waterfront promenade

The Four Seasons Residences' defining view. At this address — directly above the Seattle waterfront — western exposure delivers the most complete Elliott Bay panorama in the city. These units represent the highest price-per-square-foot of any Seattle condominium.

North / Northwest

Puget Sound, Belltown waterfront, Olympic Peninsula

North-facing residences at this elevation deliver the full Olympic Peninsula and north Puget Sound — a quieter water view than the west-facing units but equally expansive at the upper floors.

East

Pike Place Market, downtown Seattle core, Cascade Mountains

East-facing units look directly over Pike Place Market rooftops toward the Cascade range — an unusual urban-historic view angle. The value tier inside the building, still at a significant premium relative to the broader Seattle condo market.

South

Pioneer Square, the waterfront, Elliott Bay south, Mount Rainier

South-facing residences deliver the full length of the Seattle waterfront and Elliott Bay south, with Mount Rainier framed against the bay on clear days — a view angle only buildings at this waterfront position can offer.

Location & commute

The Seattle waterfront. Pike Place. Pioneer Square. All within walking distance.

99 Union Street sits at the intersection of the waterfront promenade and downtown Seattle. Pike Place Market is two minutes on foot. The ferry terminal is four minutes. Pioneer Square is eight. For buyers who want the complete Seattle urban experience within walking distance of home, this address is the center of the map.

Why work with RexMont

2–4 transactions per year. Every one requires bespoke strategy.

The Four Seasons Residences may close 2–4 resales in a given year across the entire building. There is no meaningful "building average" to anchor to — every transaction is individually negotiated and priced. RexMont approaches Four Seasons representation as a bespoke engagement with global buyer outreach and unit-specific pricing analysis.

36 residences — the most exclusive ownership community in Seattle

The Four Seasons Private Residences has 36 homes. That's fewer units than most single floors in Insignia. The ownership community is smaller than many private clubs. For buyers who want genuine privacy, exclusivity, and a building that functions more like a managed estate than a condo complex, no Seattle address competes with this scale.

Full Four Seasons hotel services — not 'access to some services'

Residents receive the complete Four Seasons hotel service stack: concierge, in-residence dining, housekeeping, spa, valet, event catering, and 24-hour security. This is the same service delivered to hotel guests, extended to private residences above the hotel. No other Seattle residential building offers this — Avenue Bellevue approximates it; the Four Seasons delivers the original.

The waterfront address is finite and irreplaceable

99 Union Street sits directly above the Seattle waterfront promenade — not near the waterfront, not a water view from a Belltown high-rise. The new waterfront park, beach access, and ferry terminal are at the building's base. There are exactly zero other luxury residential towers at this waterfront position in Seattle. The supply constraint is permanent.

Ultra-thin comp pool requires ultra-specific expertise

The Four Seasons Residences may close 2–4 resales per year. In this environment, every transaction sets the comp for the next. Pricing is not driven by building averages — it's driven by individual negotiations with deep knowledge of each unit's floor, orientation, renovation level, and the current buyer pool. RexMont approaches Four Seasons Residences representation as a bespoke engagement, not a standard condo transaction.

Selling at the Four Seasons Residences

36 units. Global buyers. Bespoke strategy required.

Selling a Four Seasons Residences unit is not a standard Seattle condo transaction. The buyer pool is global, the comp set is 2–4 units per year, and the Four Seasons brand association attracts buyers who filter by brand before they filter by market. RexMont builds every Four Seasons seller strategy around these specific realities.

36-unit exclusivity as the headline — the smallest unit count of any luxury high-rise in Seattle is the building's most powerful differentiator
Full Four Seasons hotel service access as a tangible lifestyle benefit — not a marketing line, a documented daily reality for residents
Waterfront address as an irreplaceable supply argument — no other Seattle luxury residential tower occupies this waterfront position
International buyer outreach — Four Seasons branded residences draw buyers from across the Pacific Rim and beyond who filter by brand before they filter by city
Photography and videography at the level the building deserves — the Elliott Bay and Olympic Mountain views from this address require production quality that matches the price point
Bespoke pricing strategy — Four Seasons Residences units are priced individually, not by building average. RexMont builds a per-unit case from the ground up

FAQ

Four Seasons Residences Seattle questions buyers ask us most.

What are the Four Seasons Private Residences Seattle?

The Four Seasons Private Residences Seattle are 36 ultra-luxury condominium homes on the upper floors of the Four Seasons Hotel Seattle at 99 Union Street. Developed by Nitze-Stagen and delivered in 2008, the residences sit directly above the Seattle waterfront with Elliott Bay, Olympic Mountain, and Puget Sound views. Residents receive the full Four Seasons hotel service stack.

What hotel services do Four Seasons Residences owners get?

Four Seasons Residences owners have access to the full Four Seasons Hotel Seattle service offering: 24-hour concierge, in-residence dining and room service, housekeeping, spa and fitness facilities, valet parking, event catering, and security. The scope and pricing of specific services should be confirmed in the current residences agreement, which RexMont reviews as part of the offer process.

How much do Four Seasons Residences Seattle condos cost?

Four Seasons Residences Seattle units represent the highest price-per-square-foot of any residential building in Seattle. With 36 total homes and 2–4 resales per year, each transaction is individually negotiated and priced — there is no meaningful building average. RexMont contacts owners and tracks every Four Seasons Residences transaction to advise buyers on current market positioning for any specific unit.

Are there any other buildings in Seattle comparable to the Four Seasons Residences?

Nothing in Seattle directly competes at the Four Seasons Residences level. The combination of 36 total units, full Five-Star hotel services, and a direct waterfront position is unique in the market. Avenue Bellevue in Bellevue offers a hotel co-location model (W Hotel) with a similar luxury residential stack. For pure Seattle waterfront luxury with international brand association, the Four Seasons Residences has no true comparable.

Is the Four Seasons Residences a good investment?

The Four Seasons Residences' investment case is built on three factors: brand permanence (Four Seasons as an operator), supply constraint (36 units, waterfront position, no competitive pipeline), and international buyer liquidity (Four Seasons branded residences attract buyers globally who filter by brand). These factors have historically supported strong value retention through market cycles. Specific investment returns depend on unit selection, timing, and HOA cost trajectory. RexMont advises clients on current market data for any unit under consideration.

What are the HOA fees at the Four Seasons Residences Seattle?

HOA dues at the Four Seasons Residences reflect both the cost of hotel-grade building management and the per-unit operating share across only 36 homes. These are among the higher HOA costs in the Seattle condo market — expected at this service tier. RexMont reviews the current HOA budget, reserve study, and operating cost breakdown in detail before any offer.
