Dale Garnett saw this coming

Dale Garnett was talking about demand.

In December 2024, as Side Out Pickleball Centers opened its first facility in Everett, Garnett, a co-founder of the company, told 425 Business, "We've had a lot of memberships and people ready to play". The next day he told Fox 13 Seattle, "It's hard to believe the Seattle metro area hasn't had a dedicated indoor pickleball-exclusive facility until now…the demand is huge". The same December release also announced a second, far larger building to come.

That building, at 2300 26th Ave S in south Seattle, would eventually hold 26 indoor courts across nearly 100,000 square feet (98,577, according to public reporting), three of them built for championship play. Garnett is now the facility's Operating Partner.

Inside Sideout Tsunami's warehouse

Twenty-six courts fill a single level at Sideout Tsunami, three of them built for championship play.

A café and a two-storey viewing deck split the room down the middle, so spectators watch from above instead of walking behind live games. A beer garden, private meeting rooms and free parking round out the building.

Every core membership says wait

Nearly two years after Garnett's prediction, Sideout Tsunami's own membership page tells a plain story.

Tsunami Solo costs $150 a month for one player, Tsunami Duo $270 for two ("Doubles partners and couples"), and Tsunami Clan $320 for a whole household ("Families living at the same address").

Cheapest or priciest, the result is the same: all three are marked Waitlist, each with a $100 initiation fee and 20 days' notice to cancel. Each tier's "Join the waitlist" button leads to the same line: "Join the waitlist and we'll be in touch as places open up". The page does not say how many people are already on it.

Two doors stay open

Two membership tiers never got the waitlist treatment.

Tsunami Sunrise and Side Out Senior both cost $75 a month, and both are live and bookable. Sunrise opens the courts to early risers for free play from 6 to 9 a.m.; Senior, for players 65 and older, extends that free window from 6 a.m. to noon.

Anyone else can still walk in without joining anything, paying $15 an hour per player for a court, or $25 per player for a three-hour open-play session. Those open-play sessions can fill up fast on their own terms. The Intermediate and Advanced sessions for Wednesday, October 14, were full a day ahead, with waitlists of 60 and 59 people, numbers that measure a single evening, not the open-ended wait for a membership.

The weekly court sheet

The court sheet gets specific about who plays when.

Court 24 is reserved as an advanced challenge court, where the winning team stays on with no game limit, while Court 2 caps intermediate players at three games before they rotate off. Five recurring leagues share the week, among them the Honcho League, the Westside Pickleball League and a Winter Queer League. Devin Schmidt directs instruction; Cai Haught directs pickleball programming.

The room also hosts its own crews. A recurring social called "Pickleball Social Open Play Hosted By 1.5 Gen Asians" has run there repeatedly through 2026, and in August an AREAA Greater Seattle charity tournament, organized by board member Aaliyah Mitchell, used the courts too. The courts have also carried "Paddles for a Purpose Open Play", a fundraiser for Treehouse for Kids.

Finding the building and a court

Sideout Tsunami Pickleball Center sits at 2300 26th Ave S, in south Seattle.

The building is a converted bottling-plant warehouse between Martin Luther King Jr. Way S and Rainier Ave S, open seven days a week, 6 a.m. to 11 p.m. Booking for members and the public alike runs through CourtReserve, and membership is not required.

Anyone can register and show up under the walk-in rates, sorted into sessions by skill level: Novice, Intermediate, Advanced, or a DUPR-gated court for anyone already rated above 4.2. A club announcement in October added a Monday Open Play Trial from 5 to 8 p.m., set to start October 26, aimed at spreading out the facility's busiest evening hours. The core memberships are still waitlisted. Monday night is the facility's newest attempt to make room anyway.
