Ada County property assessments are out. How home values changed where you live
Ada County homeowners will likely see modest increases in their property values this year.
Annual property assessment notices are out, and the latest data from the Ada County Assessor’s Office shows that median home values are up this year across every listing-service region. But in many regions, the growth is minute. And in almost all, it’s smaller than it’s been in recent years.
Countywide, median property values rose roughly 1.6% this year, according to data from the assessor’s office website. Last year, the jump was 5.3%. Residential property values leveled off at almost identical rates.
That puts median assessed values just shy of $471,000 in Ada County this year, compared with $463,500 last year. For just residential properties, median assessments are slightly higher, at $477,400 this year and $470,000 in 2025.
“Overall, the 2025 and early 2026 markets have been pretty sedate,” said Chief Deputy Assessor Brad Smith in an email to the Idaho Statesman. Those “moderate” changes in property values track across various property types, price points and market areas, Smith said.
Smith placed that growth in contrast with the more volatile market that property owners experienced during and following the COVID-19 pandemic, when many property values soared through 2022, then dropped significantly in 2023.
Since 2023, property values have been steadily increasing, with growth slowing this year. The latest jump puts the county within throwing distance of its 2022 peak, when the median countywide assessed property value was just shy of $494,000, the data shows.
These are the key takeaways from this year’s data:
Where home values are growing fastest in Ada County
Leading the county in home value growth was a segment of Garden City, according to data from the Assessor’s Office showing increases by residential market area, also known as listing-service area.
Garden City’s listing-service area, which encompasses most of southeastern Garden City, saw a 5.6% increase in median home values in 2026. The growth spurt brings median home values in the area to roughly $424,000, according to the Assessor’s Office.
Southwest Boise followed Garden City, with median home values growing 3.4%, translating to roughly $487,000. All other market areas grew by less than 3%, the data showed.
Northwest Meridian and Kuna’s market areas saw the slimmest increases, at 0.1% each, followed by Eagle’s market area, which saw a 0.3% increase.
Eagle’s market area, which extends north from Chinden Boulevard between Idaho 55 and Idaho 16, boasts the highest median home value, at nearly $808,000.
Citywide, Eagle’s median home values are lower, but they still top the county, at $767,000.
Kuna had the lowest citywide median assessed home value, at $410,400, the data showed.

This graph reflects the median assessed property values for only “improved,” or developed, residential properties. It excludes residential properties that are vacant.
‘Sedate’ growth, except for this one property type
According to Smith, one property type managed to “buck the trend” of slim growth: “High-end residential.”
“The pool of potential buyers is smaller, but high-end luxury properties continue to break pricing records,” Smith said.
Mark Southard, an appraisal analyst for the Assessor’s Office, added in an email to the Statesman that these properties have been “somewhat more resilient than many entry-level and mid-priced homes” during this assessment cycle.
“One reason may be that buyers in the upper-end market are often less dependent on mortgage financing and therefore less sensitive to elevated interest rates,” Southard said. “While current mortgage rates are not especially high by long-term historical standards, they remain significantly higher than the unusually low rates experienced during the years following the 2008 recession.
“As a result, affordability pressures have been more pronounced in the entry-level market despite continued demand.”
What this means for homeowners’ tax bills
Annual assessments were mailed to property owners over Memorial Day weekend.
These notices tell owners the county assessor’s estimate of a property’s market value as of Jan. 1, Southard said. They are not tax bills and do not, by themselves, determine how much owners owe in property taxes, he clarified. That amount also depends on how much local jurisdictions decide to collect.
“Property taxes are calculated later in the year after the various taxing districts establish their budgets and tax rates,” he said.
Property owners can expect their annual property tax bills from the Ada County treasurer in November, Southard said. The first half of the bill is due in December, and the second half is due in June 2027.
