Ada County tax deed sales, Idaho

Verified

Ada is the Boise county, and its published auction results show how small the lists can be and how wide the outcomes run. The October 13 to 16, 2025 sale offered three parcels, one drew no bids, and a single parcel in the April 8 to 10, 2026 results sold for $330,301.00 against a $10,765.99 minimum bid, creating $319,535.01 in excess proceeds. Minimum bids here are often only the taxes, penalty, interest and sale costs, so bidding, not the opening price, sets the real price.

Next sale: No future auction date is published on the county pages. The most recent auction in the county results ran April 8 to 10, 2026, following an October 13 to 16, 2025 sale.. The treasurer says the auction is usually held in late summer or fall and the hearing that feeds it is held once a year on a date that varies. Watch the treasurer Property Auction and Tax Delinquency pages and the posted parcel list, which appears about one week after the hearing.

Plan around a hearing once a year and an auction that usually follows in late summer or fall, with the parcel list posting about a week after the hearing. Dates move from year to year, so the treasurer pages are the place to watch.

Research Ada County parcels before you bid

A sale list gives you the parcels, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across Ada County, searchable by address, owner, or county, including parcels that never reach a sale list.

How Idaho tax deed sales work

• Taxes go delinquent and the lien belongs to the county. A delinquency carries interest at 1 percent per month from the January 1 after the lien attached, and the county holds a perpetual lien that entitles it to a tax deed (Idaho Code 63-1001 and 63-1003).
• Three years pass with no investor product to buy. There is no lien sale and no certificate in Idaho; during the wait the only event is the county building its own deed.
• Notice of pending issue goes out. Between five months and two months before the deed date, the tax collector serves notice on the record owner and parties in interest by certified mail with return receipt requested; if the mail comes back undelivered, a summary is published once a week for four consecutive weeks, and an affidavit of compliance is recorded at least five working days before the deed (Idaho Code 63-1005).
• The commissioners hold a hearing. If the tax collector followed the notice statute and the delinquency is still owing and unpaid, the board directs the tax collector to issue and record the tax deed to the county (Idaho Code 63-1006).
• Redemption stays open after the deed. The former owner or a party in interest may redeem until the commissioners contract to sell the property or transfer it by deed, and never later than 14 months from tax deed issuance, by paying the delinquency with interest and costs, including title search and professional fees, plus taxes accrued after the deed (Idaho Code 63-1007).
• The commissioners auction the property. The auction must be held no later than 14 months from issuance of the tax deed, on newspaper notice at least ten calendar days ahead naming the taxpayer and the legal description, and the minimum bid is set to include all taxes owing, interest, and costs (Idaho Code 31-808).
• Excess proceeds are claimed, not kept. Money above everything owing is apportioned first to parties in interest who claim within 60 days of the board notice, in lien priority, and the remainder goes to the owner of record at the time the tax deed issued (Idaho Code 31-808).

How buying works in Ada County

The county delinquency page does not publish a bidder registration procedure. Registration and bidding steps, when an auction is scheduled, come with that sale, so contact the treasurer at 208-287-6800 for the current sale terms.

• Where bidding happens At the public auction the commissioners set for each group of tax deeded parcels. Idaho counties run these sales differently: Kootenai and Bonner sell online, Ada and Canyon in scheduled county sales, Twin Falls on the courthouse steps, and each county page on this site names that county venue and route.
• Deposit and payment Terms are set county by county and sale by sale; several Idaho counties require the full bid in certified funds on the day of the sale. The statement at the top of each county page carries the deposit and payment terms that county publishes, or says plainly that the county does not publish them.
• Transfer fees and the deed The purchaser also pays all transfer fees, and no deed is delivered until the deed has been recorded (Idaho Code 31-808). Most counties convey by quitclaim or county deed, so the interest bought is the interest the county holds, and nothing more.

Terms: what a bid actually costs

Parcels that receive no bids

The county results list parcels that drew no bids, for example one Eagle parcel in October 2025 and one Boise parcel in September 2024. Under Idaho Code 31-808(6), property the county cannot sell at public auction may later be sold without further notice by public or private sale on the terms the county sets. The county page does not publish a separate over the counter list for these parcels.

Before you bid

• Read the notice for the specific auction The statute sets the frame, but the notice for each sale sets the venue, the parcel list, the minimum bids, and the payment terms for that day. The county pages here link the treasurer and sale pages where those notices appear.
• Expect a quitclaim, and price the title work Most Idaho counties deed without warranty and sell parcels as is. Budget for a title search and, where the parcel matters, a quiet title action, and treat access, zoning, and condition as your own research.
• Watch the redemption tail Because redemption runs after the deed and right up to the county sale contract, a parcel on a posted list can be paid off and disappear before auction day. Recheck the list close to the sale.
