Should The Tacoma Dome House The Sonics Return?

The Tacoma Dome Case: Why the South Sound May Already Have the Arena the NBA Needs for the Sonics’ Return

The Seattle SuperSonics are no longer merely a matter of nostalgia. In March 2026, the NBA Board of Governors formally authorized the league to explore expansion to Seattle and Las Vegas, turning what had long been a civic wish into an officially recognized league-level possibility. NBA Commissioner Adam Silver said the league would evaluate prospective markets, ownership groups, arena infrastructure, and the broader economic implications of expansion. And that development forces a question that deserves considerably more attention than it has received: if professional basketball is coming back to the Puget Sound, must the new team necessarily play in Seattle? Or could the most practical home for the next generation of Sonics basketball already be sitting just 35 miles south of the city's traditional basketball center, under one of the largest domed structures in the world? The case for the Tacoma Dome is not a sentimental argument for putting Seattle's team somewhere else. It is an argument that Tacoma may possess something the region should not overlook: an existing, publicly owned, enormous, flexible, transit-connected building with actual SuperSonics history, proven NBA-scale capacity, and a demonstrated ability to host the franchise when Seattle's own arena was unavailable.

The historical connection is stronger than many casual observers realize. The Tacoma Dome opened in 1983, and the SuperSonics played their first exhibition game there on October 9 of that year, facing the Portland Trail Blazers. The team subsequently played four regular-season games at the Dome during the 1983–84 season and another four during the 1984–85 season. The Tacoma experiment was not merely symbolic: the Sonics averaged 11,852 spectators during those four 1983–84 Tacoma regular-season games, a figure that exceeded their average attendance at the Kingdome that season. The franchise ultimately returned to Seattle Center, but Tacoma had already demonstrated that the Dome could function as a home for NBA basketball.

Then came the moment that permanently connected Tacoma to the history of Seattle basketball. When the Seattle Center Coliseum underwent its extensive renovation following the 1993–94 season, the Sonics relocated their home games to the Tacoma Dome for the entire 1994–95 season. The Dome therefore was not simply a venue where the Sonics occasionally appeared; it served as the franchise's home for 41 games during an actual NBA season. That history changes the question. Tacoma is not proposing itself as an experimental basketball market with no relationship to the franchise. The region has already used Tacoma as the operational solution when Seattle's principal basketball building was unavailable.

The building itself remains an extraordinary piece of infrastructure. The Tacoma Dome is owned and operated by the City of Tacoma and is described by the venue as one of the largest wood-domed structures in the world. Its flexible configurations can accommodate between 1,000 and 21,000 patrons, making it the largest indoor venue in Washington. Its dimensions are equally striking: the dome is approximately 530 feet in diameter and 152 feet high, while its enormous structural grid spans approximately 384 by 160 feet. For an NBA franchise, the significance is obvious. The Tacoma Dome does not have to prove that it can contain an NBA-sized crowd in theory; its historical NBA configuration reached a maximum capacity of approximately 22,000 during the Sonics era. The current venue advertises configurations accommodating up to 21,000 patrons, which still places it firmly in the major-arena category.

That is where the Tacoma Dome becomes particularly interesting when compared with the obvious competitor: Climate Pledge Arena in Seattle. Climate Pledge is unquestionably the more modern building. The former Seattle Center Coliseum was transformed beneath its historic roof through a massive privately financed redevelopment that opened in 2021. Today, Climate Pledge Arena has an official basketball capacity of 18,300 and serves as the home of the Seattle Storm and NHL's Seattle Kraken. It is precisely the kind of facility an NBA expansion committee would expect to see in a modern professional sports market. Seattle's political leadership is also openly positioning the arena for a Sonics return, with the Seattle City Council stating in 2026 that Climate Pledge Arena was constructed to be NBA-ready.

So why Tacoma? Because the competition is not simply about which building is newest. It is about what the region needs from a professional basketball facility and what each venue can realistically offer. Climate Pledge has the advantage of being in Seattle, at Seattle Center, beneath the same historic roof associated with the Sonics' most famous era. It has modern premium spaces, an 18,300-seat basketball configuration, established NHL and WNBA operations, and a sophisticated urban location. It would be difficult to argue that Climate Pledge is not a legitimate candidate. But that does not automatically eliminate Tacoma. In fact, it creates a fascinating regional alternative: Seattle already has a premier arena serving two major professional franchises, while Tacoma has a giant public venue with historic Sonics credentials that could potentially provide another model for NBA basketball in the Puget Sound.

The Tacoma Dome's greatest advantage may therefore be its sheer flexibility. The venue was designed as a multipurpose building rather than a facility locked into one primary professional sports configuration. Its telescoping seating and extensive curtaining system allow the interior to be configured for dramatically different events. The Dome says its configurations can accommodate audiences from 1,000 to 21,000. That flexibility matters to an NBA expansion franchise because the economics of professional basketball extend far beyond 41 home games. Concerts, family entertainment, college sports, tournaments, conventions, community events, and other major productions can all compete for dates. A building capable of transforming itself for different audiences has a fundamentally different business model from a venue optimized around a narrower range of permanent configurations.

There is another major difference between the Tacoma Dome and Climate Pledge that deserves attention: ownership. Climate Pledge Arena's redevelopment was privately financed by Oak View Group and its partners under a long-term lease arrangement with the City of Seattle. The city states that the project was financed entirely by OVG, with the current project cost estimated at $1.15 billion, while OVG bears the project's construction and operating cost risks under the arrangement. The Tacoma Dome, by contrast, is owned and operated by the City of Tacoma. That does not automatically make Tacoma the better NBA market, but it presents a different institutional model that could become relevant in negotiations involving an ownership group, the city, the region, and the league.

Transportation is another part of the Tacoma argument that deserves to be separated from the simplistic assumption that an NBA team must be physically located in Seattle to be accessible to the Seattle metropolitan population. The Tacoma Dome sits adjacent to Tacoma Dome Station, a major regional transportation hub served by Sound Transit, Pierce Transit, and other services. Sound Transit specifically identifies the Tacoma Dome as accessible via the T Line, Sounder S Line, and local bus service. The Tacoma Dome's own transportation information identifies the Tacoma Dome Station as a regional hub connecting the area with bus and commuter rail service, while the surrounding district provides access to Tacoma's downtown restaurants, retail, museums, and other destinations. The current regional transportation system therefore already recognizes the Dome as a destination capable of absorbing large event crowds.

The future transportation picture could make that location even more consequential. Sound Transit's Tacoma Dome Link Extension is planned to add approximately 8.5 miles of mostly elevated light rail between Federal Way and Tacoma, with proposed stations at South Federal Way, Fife, East Tacoma/Portland Avenue, and the Tacoma Dome area. Sound Transit says the project is currently in environmental review, with the Final Environmental Impact Statement expected in 2027 and the Board expected to select the project to be built afterward. The agency projects that the eventual extension could connect Federal Way to the Tacoma Dome area in approximately 20 minutes and Tacoma Dome to Sea-Tac Airport in approximately 35 minutes. In other words, Tacoma's location is not frozen in today's transportation map. The regional transit system is actively planning to make the Tacoma Dome area an even more significant regional transportation node.

That does not mean the Tacoma Dome is without weaknesses. Its parking situation is one of them. The Dome itself acknowledges that parking is limited and can sell out during large events, encouraging visitors to use public transportation, rideshare, or downtown Tacoma parking. Interstate 5 access can also become challenging during major events, and the venue specifically advises against using Exit 133 during high-volume events because that exit is generally closed and traffic is rerouted. An NBA franchise playing dozens of home games each year would therefore need a sophisticated transportation and traffic-management strategy rather than simply assuming that existing parking would be sufficient.

But here is where the comparison becomes more interesting: Climate Pledge Arena has its own transportation challenges precisely because it sits in one of the densest and most congested parts of the region. Its location at Seattle Center is a tremendous urban advantage, but it also means that an NBA team would be sharing a highly desirable urban campus with existing professional sports, entertainment, cultural, and convention activity. Climate Pledge currently operates as the home of the Kraken and Storm while hosting hundreds of other public and private events. The question for an NBA expansion committee would therefore not simply be, "Which arena is better?" It would be, "Which arena arrangement produces the strongest long-term regional sports ecosystem?"

The other Puget Sound venues demonstrate why Tacoma stands out. The accesso ShoWare Center in Kent is a legitimate multipurpose arena with strong freeway access, free parking, 20 suites, and flexible configurations ranging from approximately 1,500 to 7,300 seats. It is home to the Seattle Thunderbirds and Tacoma Stars and hosts more than 200 event days annually. It is an excellent regional entertainment facility, but its scale immediately separates it from an NBA proposition. At roughly 6,500 seats in its standard configuration, ShoWare is simply not an equivalent competitor to a building capable of accommodating more than 18,000 basketball spectators.

Farther north, Angel Of The Winds Arena in Everett provides another useful comparison. Opened in 2003, the arena is home to the Everett Silvertips and can accommodate up to 10,000 guests. It is an established professional sports and entertainment facility in Snohomish County, but again, its capacity places it in a fundamentally different category from an NBA arena. Everett has the advantage of representing the northern portion of the metropolitan region, but it would require a substantially different arena proposition to compete directly with Climate Pledge or the Tacoma Dome for an NBA franchise.

That leaves the Puget Sound with an unusual hierarchy. Climate Pledge Arena is the modern Seattle option at approximately 18,300 basketball seats. Tacoma Dome is the giant South Sound option, capable of accommodating up to 21,000 under its current configurations and historically configured for approximately 22,000 for NBA games. ShoWare Center and Angel Of The Winds Arena are important regional facilities, but their capacities are substantially smaller. The question is therefore not whether Tacoma possesses a legitimate arena. It plainly does. The question is whether the region should consider the Tacoma Dome a legitimate NBA arena solution.

There is an argument that Tacoma could offer something Seattle cannot: geographic expansion without abandoning the Seattle identity. A Tacoma-based Sonics team could potentially become the Puget Sound's NBA franchise rather than merely Seattle's basketball tenant. Seattle, Bellevue, Renton, Kent, Federal Way, Tacoma, and the surrounding communities are not isolated sports markets. They are interconnected by highways, commuter rail, buses, and an expanding light-rail system. The Tacoma Dome's location at a major transportation hub places it in a position to draw from both the South Sound and the broader metropolitan region. Sound Transit's existing services and planned expansion reinforce that regional character.

There is also something symbolically powerful about returning the Sonics to the building that once sheltered them when Seattle could not. The 1994–95 season demonstrated that the franchise could operate out of Tacoma without ceasing to be the Seattle SuperSonics. That historical fact should not be treated as a footnote. It is perhaps the strongest evidence available that the Tacoma Dome can be integrated into the identity of the franchise rather than treated as an outsider to it. When the Seattle Center Coliseum was unavailable, the Sonics did not cease being Seattle's team. They played in Tacoma.

There is another argument that deserves consideration: scarcity. The Puget Sound does not need three NBA-sized arenas. It needs the right combination of venues capable of supporting different levels of professional and entertainment demand. Climate Pledge already has a powerful position at Seattle Center, with the Kraken, Storm, major concerts, NCAA events, and other programming. A returning NBA team would therefore enter an already crowded sports and entertainment ecosystem. Tacoma could provide geographic diversification while allowing the region to maintain Seattle Center as its premier urban sports-and-culture campus.

That possibility becomes even more intriguing because the NBA itself is now officially examining Seattle's expansion prospects. The league has authorized formal exploration of Seattle and Las Vegas, and it has specifically stated that arena infrastructure will be part of its evaluation. The conversation has therefore moved beyond whether Seattle deserves another team. The more consequential question is what infrastructure and ownership model can sustain one. If the league is evaluating arena infrastructure rather than simply city names, then Tacoma deserves to be sitting at the table.

Of course, the Tacoma Dome would require serious evaluation before anyone could responsibly declare it NBA-ready in its present condition. Modern NBA standards encompass much more than seating capacity. Premium seating, player facilities, locker rooms, media infrastructure, broadcast operations, technology, concessions, accessibility, security, hospitality, sponsorship inventory, practice facilities, and revenue-generating spaces would all need to be assessed. The fact that the Dome once hosted NBA games proves historical viability; it does not automatically prove that every modern NBA requirement is currently satisfied. The distinction is important.

But that is precisely why Tacoma should not be dismissed. The question is not whether the Dome is already perfect. The question is whether it provides a sufficiently strong foundation to justify investment. A 21,000-capacity publicly owned multipurpose facility with a genuine SuperSonics history and direct access to a regional transportation hub is not something a prospective ownership group should casually overlook.

The case becomes even more compelling when viewed through the history of the franchise itself. The Sonics have already occupied the Seattle Center Coliseum, the Kingdome, and the Tacoma Dome during their history in the region. The franchise's identity was never exclusively dependent upon one physical building. What made the Sonics the Sonics was the relationship between the team and its Pacific Northwest audience. The Tacoma Dome has already been part of that relationship.

The NBA's renewed interest in Seattle therefore presents Tacoma with an unusual opportunity. Rather than waiting for Seattle to determine whether Climate Pledge Arena will be the exclusive destination for professional basketball, Tacoma could make its own case: not as a consolation prize, not as a temporary relocation site, and not as a second-rate substitute for Seattle, but as a legitimate South Sound home for a regional NBA franchise.

The argument ultimately comes down to a simple proposition. Climate Pledge Arena may be the obvious answer because it is in Seattle, is modern, is already configured for basketball, and was explicitly designed with NBA compatibility in mind. But obvious does not necessarily mean only. The Tacoma Dome has the historical precedent, the scale, the flexibility, the public ownership structure, the transportation connections, and the geographic opportunity to make the conversation much bigger than Seattle proper. Its own history tells us that the Sonics have already called Tacoma home when circumstances required it.

So perhaps the question for the next Sonics ownership group should not simply be, "Where in Seattle will the team play?" Perhaps the more ambitious question is, "Where can the next generation of Sonics basketball serve the entire Puget Sound?" If the answer is supposed to involve an arena capable of hosting NBA-scale crowds, a location connected to regional transit, a facility with demonstrated professional-basketball history, and an opportunity to expand the economic and cultural footprint of the franchise beyond Seattle's urban core, then the Tacoma Dome deserves something more than a nostalgic mention.

It deserves a serious bid.

Because the Tacoma Dome has already done something no prospective venue can manufacture overnight: it has already been home to the Seattle SuperSonics. The NBA is now once again looking toward Seattle. The arena question is coming. When that question arrives, Tacoma should not be asking permission to participate in the conversation. It should be making the case that the Dome has been waiting for another chance since 1995.

And perhaps the most provocative question of all is the simplest one: if the NBA is returning to the Puget Sound, why should the next chapter of the Sonics story be confined to the city limits of Seattle when the franchise has already proven that its home court can be somewhere else?
