Nampa and Caldwell hold most of that renter base.

Rents, growth and affordability

Median gross rent in Canyon County rose 50.3%, from $896 to $1,347, between the 2015-2019 and 2020-2024 American Community Surveys. Median household income grew faster still, up 46.7% to $76,488, while employment rose 23.4%, adding 22,588 jobs.

Renter households actually fell 5.2% over that stretch, a drop of 1,151 households, even as population climbed 15.2%. That points to Canyon County renters moving into ownership as incomes rose. Units in buildings of five or more apartments grew 11.3%, adding 446 units, to reach 4,399 units countywide. That share of the stock, 4.9% of all housing units in Canyon County, still trails many urbanized Idaho markets, which keeps well-located 5+ unit buildings in Canyon County relatively scarce.

Rent burden remains high. In the 2020-2024 ACS, 48.6% of Canyon County renters paid 30% or more of income toward gross rent. HUD's FY2027 two-bedroom Fair Market Rent for the Boise City, ID HUD Metro FMR Area is $1,540, effective October 1, 2026, which runs $193 above the county's median gross rent.

City-by-city comparison

Nampa is the larger apartment market within Canyon County, with 7.2% of its housing units in 5+ unit buildings against Caldwell's 6.1%. Nampa also posts the higher median gross rent and the tighter renter share of its own households.

Caldwell's 5.6% rental vacancy runs well above Nampa's 3.9% and the 3.9% countywide rate for Canyon County. Nampa's rent grew 53.5% since the 2015-2019 survey, slightly ahead of Caldwell's 44.0% gain, keeping Nampa the pricier of the two Canyon County cities on a median-rent basis. Both cities still post rental vacancy under 6%, which tells a Canyon County buyer that demand has kept pace with the new apartment supply added since the 2015-2019 survey.

Property taxes and assessment in Canyon County

Idaho assesses real property, including apartment buildings, at market value as of January 1 each year under Idaho Code 63-205(1). The Canyon County assessor applies that standard locally, and taxing districts in Idaho face a combined 3% budget-growth factor plus new construction, capped at 8% overall under Idaho Code 63-802.

Idaho bars local rent control outright. Idaho Code 55-306 prevents any city or county, including Canyon County, from setting rent, fees or deposit limits on private leases, which keeps rent decisions with the owner rather than local ordinance. Canyon County has no separate real estate transfer tax, though a seller should still confirm recording fees with escrow before closing.

What this means if you sell in Canyon County

If you plan to sell commercial property in Canyon County, ID, the renter pool is smaller than in many metro counties, at 24.5% of households, but it is concentrated: Nampa and Caldwell together hold 83.0% of Canyon County's renter households. A 3.9% rental vacancy rate signals steady lease-up, which buyers will check against your trailing occupancy.

Expect a buyer to model the next Canyon County reassessment at full market value under Idaho Code 63-205(1), not your current tax bill. With no rent control under Idaho Code 55-306, rents stay market-set, which simplifies underwriting for an apartment buyer in Canyon County.
