San Diego County tax sales, California

Verified

San Diego sells once a year in March, online through Grant Street Group at sdttc.mytaxsale.com, not on Bid4Assets. The 2026 sale, Online Public Auction Tax Sale No. 7102, ran March 13 to March 18, 2026 and opened with 686 properties, including 70 improved properties, 66 unimproved properties, and 550 timeshares. The board item approved 793 parcels before redemptions shrank the list, which is the normal pattern here. No dated 2027 sale was published when read November 9, 2026, so the March pattern is the planning fact, not a date.

Selling office: San Diego County Treasurer Tax Collector

Next sale: No dated sale published as of November 9, 2026. The county pattern is one online sale a year in March. The last dated sale was March 13 to March 18, 2026. No dated sale for 2027 was published on the county tax sale pages.

San Diego is a large, timeshare heavy sale: 686 properties at the open of the 2026 auction, with a stated $18.2 million in tax revenue if every property sold at its minimum bid. Expect the next announcement in the winter before a March sale, based on the 2026 pattern.

Research San Diego 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 San Diego County, searchable by address, owner, or county, including parcels that never reach a sale list.

How California tax defaulted property sales work

• Default runs on a five year clock. Property taxes that go unpaid become tax defaulted. After five years of default (three years for nonresidential commercial property and the other classes the code names), the property becomes subject to the tax collector's power to sell under Revenue and Taxation Code Section 3691. Until that clock runs, there is nothing to buy: California sells no tax liens.
• The county sets a Chapter 7 auction. With the board of supervisors' approval, the tax collector publishes notice and offers the property at public auction under Chapter 7 of Part 6. The minimum price is set by Section 3698.5(a): not less than the total amount necessary to redeem the property, plus costs. Most of the counties in this set now sell online under the electronic auction provisions (Section 3692.2); the county's own tax sale page names the platform and the terms.
• The owner can stop the sale until the last business day. Redemption stays open until the close of business on the last business day before the sale begins (Section 3707), and a redemption in full ends the power to sell that parcel. Parcels are pulled right up to that deadline, so a list researched a week out is not the list that sells.
• The sale is an auction of the property itself. The highest bidder at or above the minimum wins. Counties gate bidding behind a refundable deposit funded days ahead, and winning bids are due in full on the deadline the county terms set, usually within days of the close. A winner who does not pay forfeits the deposit and the parcel returns to inventory.
• The buyer receives a tax deed, and unsold parcels come back as reoffers. The tax collector issues a tax deed under Section 3712; there is no redemption after the sale. A parcel that draws no bid at the minimum is not finished: under Section 3698.5 the tax collector may offer it again, including at a reduced minimum, and Chapter 8 (Section 3771 and following) routes some properties to public agencies and nonprofits instead. The leftover channel in California is a second, cheaper auction, and it is part of the pricing decision on the first one.

How bidding works in San Diego County

Register at sdttc.mytaxsale.com, the Treasurer Tax Collector tax auction website run by Grant Street Group. For the 2026 sale the deadline was Thursday, March 5, 2026, about a week before bidding opened. The registration deadline for a 2027 sale is not published as of November 9, 2026 and must be taken from the next sale terms when the county posts them.

• The deposit gate is real. California online sales close registration and deposit funding days before the auction opens, and an unfunded deposit cannot bid. The deadline that decides whether you are in the sale is the deposit deadline, not the auction date.
• Payment clocks are short and enforced. Winning bids come due on the county's deadline, often within days of the close, and a missed payment forfeits the deposit. Fund the maximum bid before the auction opens, not after it closes.

Terms: what a bid actually costs

Reoffers and parcels that do not sell

If no acceptable bid is received at the Section 3698.5 minimum, the Treasurer Tax Collector may, with the board approval already given in the 2026 resolution, offer the same property at the sale or the next scheduled sale at a reduced minimum the collector deems appropriate in light of the most current assessed valuation. The board item also states that any parcel remaining unsold may be reoffered within a 90 day period under Section 3692(e). The owner right of redemption revives for a parcel that does not sell, which is why reoffer lists are always smaller than the first list.

Before you bid

• Work the list twice. Redemption pulls parcels until the close of business on the last business day before the sale. The list a county publishes at notice is the research list; the list that actually sells is shorter. Re-check the morning the auction opens.
• As is, and the deed is not a policy. No interior access, occupants may be in place, and the tax deed's statutory exceptions leave title homework behind the sale. Drive the property, read the county disclosures, and budget the title and cleanup work.
• Price the reoffer before the first sale. Parcels that draw no bid at the minimum return under Section 3698.5, sometimes at a reduced minimum. Decide in advance whether you are a first round buyer at the statutory floor or a reoffer buyer waiting for the second price.
• Set the maximum before the sale opens. The free Max-Bid Calculator below works backwards from your resale or hold value to the highest bid you can pay, with the costs shown.
