For buyers with a Promontory purchase in motion before September 15, 2026, the key deadline was 5:00 p.m. on September 14.
That was the hour Promontory Club had set as the funding deadline for anyone hoping to lock in a $300,000 Full Membership deposit instead of the $500,000 figure that took effect September 15. The club's membership application window, which closed August 20, had already come and gone. The narrow, mechanical question for buyers then was whether their purchase could close and their membership fund before the clock ran 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 in the same announcement: Promontory retired the membership structure that let full access pass down through a family indefinitely and replaced it with a hard cap. Two homes in the same neighborhood, finished by the same builder, can carry different membership terms.
What Changed at 5:00 p.m.
Here's the mechanism that applied before the change. For any Full Membership transferred with a resale property, the transaction had to close and fund by 5:00 p.m. on September 14, 2026, to lock in the then-current $300,000 deposit. Anything that funded on or after September 15 fell under the new $500,000 figure. There was no partial credit and no proration. It was 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 and Its Resale Implications
Before September 15, 2026, a Full Membership could extend vertically. That meant a member's adult children, and in some cases grandchildren, could inherit access to the club without buying their own membership. It was 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. Buyers comparing similar homes should confirm which membership terms apply.
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. The change places Promontory's Full Membership deposit at the same $500,000 level as Marcella Club's, while Promontory's family-membership terms differ.
Membership, Sales and Club Investment
The deposit increase came amid changes in membership availability and sales activity. 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.
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
What did this mean for a home already under contract? It depended on when the transaction closed and funded, not on when the contract was signed. A deal that closed and funded after 5:00 p.m. on September 14 fell 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.
Was the deposit the only thing that changed? No. The cap on qualifying family members, the age-29 cutoff for children, and the shift away from multigenerational transfer were separate changes from the deposit increase, and applied to any Full Membership issued after the September 14 cutoff regardless of price.
