Kuna Just Split Its Housing Market Into Two Different Deals

Two homes hit the market in Kuna this summer within a few blocks of each other. One is a new build in a subdivision like Lugarno Terra, priced off a builder's spec sheet. The other is a resale a few years old, priced by an owner watching what the neighbors' houses are doing. Round both to the nearest ten thousand and they can look almost identical on a portal search. They are not the same deal anymore, and the difference has nothing to do with square footage or countertops.

It has to do with a fee.

What Kuna's City Council Actually Voted On in April

In April 2026, the Kuna City Council held a combined public hearing and voted to adopt Ada County's jail and EMS capital improvement plans, layering a new county-administered impact fee onto every new single-family building permit issued in the city. City planning director Doug Hansen gave the council the baseline number for context.

"Without the county fees, it would come out to approximately $10,470 in impact fees for a single-family home," Hansen said, describing that figure as the city-only portion already paid at building permit.

County staff estimated the new jail and EMS additions would tack on roughly $691 per single-family home on top of that. Add the two together and a new home permitted in Kuna after the vote carries close to $11,161 in impact fees before the builder has poured a foundation.

The hearing wasn't quiet. Kuna resident John Leroy told the council that "$691 doesn't seem like a lot of money" on its own, but urged members to weigh the cumulative effect of stacked fees on affordability. Developer Tucker Johnson pushed back from the other direction, saying he wasn't "a fan of impact fees" generally but supported a structure where "everybody pays a fair share." The council approved it anyway, waiving three readings to put the ordinances into city code the same night.

Kuna wasn't alone. By June 2026, Eagle and Star had also passed the same county fee ordinances at Ada County's urging, with Meridian moving its own version through council around the same time. Ada County's own framing for the push, offered by chief operations officer Steve Rutherford at an earlier Eagle council meeting, was blunt: the goal is to have "growth pay for itself" rather than "saddle current residents and businesses with paying for the increase." With Ada County's population projected to grow by more than a quarter between 2024 and 2050 according to regional planning estimates, city officials across the valley are reaching for the same lever at close to the same time.

Why the Fee Never Touches a Resale Listing

Impact fees are collected at building permit. That timing detail is the whole story here. A home that already exists never generates a new permit, so it never generates a new fee. The $11,161 stack applies going forward, to homes not yet built or currently under construction, not backward to anything already standing in an established Kuna neighborhood.

That creates a cost floor under new construction that resale simply doesn't have. A builder pricing a spec home in a subdivision has to account for the fee the same way they account for lumber, labor, and the lot itself. It gets built into the price sheet and it doesn't move much even if buyer traffic slows down, because the builder still owes the city the same amount at closing regardless of how the market feels that month. A resale seller has no equivalent floor. If their home sits, they can cut the price, offer a credit toward closing costs, or throw in an allowance for the neighbor's new roof estimate. A builder's fee obligation doesn't flex the same way.

Idaho law also draws a line that matters here. School districts still can't charge impact fees the way cities and counties can, which is part of why Kuna's most recent high school bond, the one that funded Swan Falls High School, cost local taxpayers $40 million when voters approved it back in 2017. Growth-related road, park, jail, and EMS costs can now be passed to new construction at the point of sale. Growth-related classroom costs still get funded the older way, through property tax bonds shared by everyone in the district. A new-construction buyer paying the fee stack at closing is not off the hook for the next school bond vote.

The Gap Hiding Under Kuna's Median

The fee floor under new construction would matter less if resale prices were holding firm against it. They aren't, at least not on the numbers from earlier this year.

As of February 2026, the median sale price for a home in Kuna sat at $450,000, up only two-tenths of a percent from the year before, essentially flat. Homes took a median of 106 days to sell that month, up from 86 days the year before, a real stretch, not a rounding difference. More homes actually changed hands that February, 119 compared to 79 the year before, so it wasn't a case of a thin market. Buyers were out there. They were just taking longer to commit at the asking price.

Sellers heading into fall 2026 are still listing at a median close to $529,000 as of August, based on current active listing data across the market, holding roughly in the same $517,000 to $529,000 range that's persisted through the spring and summer. Line that list price up against the February sale figure and the gap runs close to $79,000, something like fifteen percent of the asking price. That's not proof every seller is getting cut that hard. It is a signal that resale asking prices and what resale sellers are actually accepting have drifted apart, and that the drift has been going on for months, not weeks.

New construction doesn't have room to drift the same way. A builder like Tresidio pricing homes in Lugarno Terra from roughly $700,000, or entry-level builders such as CBH, Hayden Homes, and KB Homes working the $300,000s to $500,000s range, is pricing against fixed costs that include the fee stack. Days on market and negotiating room matter far more on the resale side of that comparison than the new-construction side right now.

What This Means If You're Comparing a New Build to a Resale Listing This Fall

A few things worth checking before assuming a price on paper means what it looks like it means:

• Ask for the permit date on a spec home. A nearly finished home permitted before April 2026 was priced under the old fee schedule. One permitted after carries the full stack. That difference belongs in your comparison even if the two houses look identical.
• Ask what the builder's base price actually includes. Lot premiums in Kuna communities can add anywhere from $20,000 to $100,000 depending on view or corner placement, on top of the fee-inclusive base.
• Check HOA dues and what they cover. In Indian Creek Ranch, an established Kuna community with creek frontage, HOA dues run in the $80 to $85 a month range for path and common area upkeep, and resales there are commonly running $600,000 to $900,000 depending on lot and finish. Get a current budget, not just the monthly number, since assessments can shift.
• Treat a resale asking price as a starting point, not a floor. With days on market running well above last year's pace, a resale seller has more reason to talk than a builder's price sheet does.

None of this means new construction is a bad deal or resale is automatically the smarter buy. It means the two no longer move together the way they used to, and pricing one against the other without accounting for the fee stack and the negotiating gap will lead you to the wrong number.

A Few Questions Worth Asking Directly

Does the new fee apply to a nearly finished spec home I'm about to buy? It depends on when the builder pulled the permit. Homes permitted before the April 2026 vote were priced under the prior fee schedule. Ask directly, it's a fair question for any builder or listing agent to answer.

Does this fee push resale prices down? Not directly. Resale pricing is still set by individual sellers reading the market. What the fee does is widen the practical gap between a builder's fixed price and a resale seller's flexible one, which shows up as longer days on market and softer sale-to-list ratios on the resale side rather than a direct price cut.

Will this show up in other Treasure Valley cities too? Likely. Eagle and Star had adopted the same county fee structure by June 2026, and Meridian was working through its own version around the same time. This looks like a valley-wide shift in how growth gets funded, not a Kuna-only policy.
