If you're reading this today, September 13, 2026, and you have a Promontory purchase in motion, the number that matters is not $500,000. It's 5:00 p.m. tomorrow.
That's the hour Promontory Club has set as the funding deadline for anyone hoping to lock in a $300,000 Full Membership deposit instead of the $500,000 figure that takes effect September 15. The club's membership application window, which closed August 20, has already come and gone. What's left is a narrow, mechanical question: can your purchase close and your membership fund before the clock runs out on Monday.
But the deposit jump, real as it is, isn't the part of this story that will still matter in five years. The part that will matter is a quieter change buried in the same announcement: Promontory is retiring the membership structure that let full access pass down through a family indefinitely, and replacing it with a hard cap. Two homes in the same neighborhood, finished by the same builder, will soon carry two different products, and the difference won't show up on the listing sheet.
What Actually Changes at 5:00 p.m.
Here's the mechanism in plain terms. For any Full Membership transferred with a resale property, the transaction has to close and fund by 5:00 p.m. on September 14, 2026, to lock in the current $300,000 deposit. Anything that funds on or after September 15 falls under the new $500,000 figure. There's no partial credit and no proration. It's a hard line drawn at a specific hour on a specific day.
The deposit is currently structured as 70 percent refundable, with annual dues around $18,000. A Social Membership, which covers everything except golf, currently runs $100,000, and an Equestrian Membership sits at $35,000. Those tiers aren't going away, but the Full Membership is the one most tied to how a Promontory home gets used and eventually resold.
The Structural Change Nobody's Deadline Countdown Mentions
Under the current, soon-to-expire structure, a Full Membership can extend vertically. That means a member's adult children, and in some cases grandchildren, can inherit access to the club without buying their own membership. It's the structure that let a Promontory home function as a multigenerational gathering point rather than a single household's amenity.
Under the new structure, membership privileges extend primarily to the purchasing couple and their qualifying children through age 29, with a cap of eight qualifying family members. Children older than 29, and future generations, are treated as guests rather than members.
Existing members keep their current vertical privileges. Those privileges are grandfathered in place. But here's the catch that matters for anyone thinking about resale value down the line: those grandfathered privileges don't transfer to the next owner when the property sells. A vertical membership dies with its current holder's ownership, not with the family. Buy a Promontory home today with a legacy membership attached, and you inherit a structure that's already scheduled to expire the moment you decide to sell.
That leaves two classes of Promontory ownership sitting side by side in the same MLS. One class, tied to memberships issued before September 15, still carries the old multigenerational structure until that specific membership changes hands. The other class, issued after the cutoff, is permanently capped. Neither class is labeled as such in a listing description. A buyer comparing two similar homes has no easy way to see which one they're actually getting unless someone tells them to ask.
Promontory isn't inventing this model from scratch. Marcella Club, one of the newer private communities in the Jordanelle corridor, already charges $500,000 for its Full Membership and doesn't offer vertical privileges at all. Promontory's change reads less like an isolated price hike and more like a older, more established club catching up to where the newest entrants in Park City's private club tier have already landed.
Why the Club Is Doing This Now
A deposit increase makes more sense once you see what's happening to the inventory underneath it. Full Golf Memberships at Promontory are currently sold out, with a waitlist that one local buyer's-agent estimate puts around 112 people. The community itself is roughly 75 percent sold, out of a planned 1,924 homesites, with somewhere near 1,000 homes completed and more than 1,400 lots already sold.
The sales numbers back up the scarcity story. Promontory closed more than $637 million in home and homesite sales in 2025, a 21 percent increase over 2024, and accounted for roughly 34 percent of all Park City home and homesite sales that year. Through mid-June 2026, an MLS export for the community showed 38 closed residential sales totaling about $248.2 million, with a median sold price near $5.6 million and a high sale of $25 million.
This is also a club investing visibly in its own infrastructure. The Village Clubhouse finished a renovation at the end of 2025 with new cardio and spin rooms, an expanded weight room, and infrared saunas. A new spa opened with ten treatment rooms and a hydrotherapy circuit. The Hills, Promontory's third golf course and an 18-hole par-3 designed by Forrest Richardson, was named 2024 Clubhouse of the Year by Golf Inc, joining the Pete Dye Canyon Course and the Jack Nicklaus Painted Valley Course, the latter measuring 8,098 yards and ranking among the longest courses in the country. In February 2026, the club also promoted longtime General Manager Kelli Brown, a 24-year veteran of Promontory and its developer Pivotal Group, to Managing Director, and brought in Jonathan Fillman, a 20-year veteran of luxury hospitality and private clubs, as the new General Manager. That's a club adding senior leadership at the same time it's raising its entry price, which points toward planned growth rather than a reaction to short-term cost pressure.
How the Math Looks Next to Tuhaye and Red Ledges
For buyers weighing Promontory against other Park City-area golf communities, the comparison isn't as simple as one deposit number against another, and the sources don't fully agree with each other. Tuhaye's Talisker Club membership has been quoted at $200,000 in some 2026 listings and $300,000 in others, depending on when the figure was pulled and which membership tier is being described. Red Ledges Golf Membership deposits have been quoted between $175,000 and $225,000 across different sources and years, with annual dues in the $12,500 to $15,600 range for that tier. Red Ledges also offers a lower-cost Golf Park Membership around $80,000 with dues closer to $8,700 to $10,800, for buyers who want course access without the full initiation.
What's consistent across those sources is that both Tuhaye and Red Ledges remain well under Promontory's new $500,000 threshold, and neither community has announced a comparable change to family membership privileges. For a buyer who plans to have adult children and grandchildren using the club for decades, that gap in family structure may end up mattering more than the difference in deposit size. A cheaper membership that still lets your grandchildren play golf without joining separately can be worth more over twenty years than an expensive one that stops extending past your own children's 29th birthday.
None of this makes Promontory a worse choice. It has three golf courses, a private ski lodge relationship with both Deer Valley and Park City Mountain, and an amenity base that took two decades to build. It makes it a different kind of purchase than it was six months ago, and a buyer evaluating a Promontory home should be asking which version of membership comes with it before comparing price per square foot to anything else on the market.
A Few Questions Worth Settling Before You Sign
Does this affect a home already under contract? It depends entirely on when the transaction closes and funds, not on when the contract was signed. A deal that closes and funds after 5:00 p.m. on September 14 falls under the new $500,000 deposit and the new family structure, regardless of when the purchase agreement was executed.
What happens to a membership I already hold? Existing members keep their current vertical privileges as long as they hold the membership. Those privileges don't automatically carry to whoever buys the property from them later.
Is the deposit the only thing changing? No. The cap on qualifying family members, the age-29 cutoff for children, and the shift away from multigenerational transfer are separate changes from the deposit increase, and they apply to any membership issued after the September 14 cutoff regardless of price.
If you're trying to figure out whether a specific Promontory property still carries the old membership terms, or whether a home in Tuhaye or Red Ledges might actually serve your family better long term, that's exactly the kind of comparison our team at Selling the Slopes works through with buyers every week.
