One number explains most of it
Park City has 8,701 housing units. 4,232 of them — 48.6% — are held for seasonal, recreational or occasional use. Across Utah, that figure is 3.7%.
Add the other vacancies and 58.7% of all housing units in Park City have no year-round occupant. The median home value is $1,757,800, against $489,400 statewide.
The full occupancy table, with Summit County alongside, is in Why Park City Costs What It Does.
Why that drives price
In most housing markets, prices are tethered to what local households earn, because local households are the buyers. Park City is not that market. The buyer for a home here frequently earns their income in California, Texas or New York, and is comparing this purchase to a second home in Jackson or Sun Valley rather than to a house in Sugar House.
That does two things at once. It unhooks price from local income, and it halves the stock available to a year-round resident. Scarce supply, non-local demand — that is the whole mechanism.
What it changes if you are buying
Listing age means less here. A seller who does not live in the home has no lease ending and no school year. Time pressure that would move a valley seller often does not exist, so a long listing is not automatically a discount.
The comparable set is narrower than it looks. Ski-adjacent, walkable Old Town and larger-lot basin properties have behaved differently for six years. Comparing across them produces bad numbers.
Carrying costs deserve a line of their own. Second-home ownership here carries HOA or club obligations, nightly-rental rules that vary by area, and maintenance for a property you are not in. Those decide more outcomes than the purchase price does.
What it changes if you are selling
Your buyer is likely on a short trip, viewing a small number of homes. Being ready during the weeks they are here matters more than being on the market for many months.
That is an argument for preparing properly before listing rather than listing early and improving later. In a market of patient sellers, the prepared home is the one that gets chosen.
The honest limits
These are Census five-year estimates covering 2020 through 2024, so they describe recent conditions, not this week. The seasonal category does not separate short-term rentals from private second homes. And the city boundary excludes much of the surrounding basin that shares the Park City name — the ZIP-level comparison shows how differently those two areas have performed.
If you are weighing a Park City purchase against staying in the valley, I am happy to put the specific numbers side by side.
