Tax deed sale
- Run by
- San Luis Obispo County Tax Collector, a division of the Auditor-Controller-Treasurer-Tax Collector-Public Administrator
- Frequency
- annual
- Typical timing
- The county runs one internet auction a year, in late spring. The auction page states: "The Internet Public Auction of Tax-Defaulted Properties begins at 8:00 a.m. PDT on May 30, 2025. The auctions close in staggered groups beginning at approximately 9:00 a.m. PDT on June 2, 2025." The same page says the property list became available in February 2025, roughly three months before bidding opened. As read in July 2026 the page still carried the 2025 sale as its most recent posted auction, so confirm the current year's dates with the Tax Collector before planning around them.
Registration and deposit
Bidders create an account on the internet auction website at bid4assets.com. A $5,000 deposit is required to take part in the real property auction. Timeshare parcels carry no deposit. Bidders must be at least 18 years old, and county employees are excluded. The winning bidder owes payment in full within 72 hours after the auction closes, by cashier's check, wire transfer, or cash. Failing to complete a purchase brings a permanent ban from future county auctions.
San Luis Obispo County sells tax-defaulted property at an online internet auction, not in person. The county's auction page names bid4assets.com as the bidding site. That site refused automated requests during this research, so the platform URL was not independently loaded and is left out here; reach it from the link on the county auction page. The county publishes the parcel list about three months ahead of bidding on its "Properties Available for Sale" page, and the same page later carries the results of the completed sale, which is what it held when checked. Parcels sell as is with no refunds, and the county warns bidders to verify access, permits, zoning, and condition before bidding. The Assessor's parcel maps and the Department of Planning and Building "Land Use View" site are the research tools the county points to. Numbered sales run in sequence; the May 2025 auction was Sale #268.

Official websiteNotes for San Luis Obispo County
- Online only. San Luis Obispo County runs its tax-defaulted property sale as an internet auction on Bid4Assets, with bidding opening on one day and closing in staggered groups a few days later.
- The $5,000 real property deposit and the 72-hour full-payment deadline are county terms, tighter than the 90-day deferred-payment window California law allows a tax collector to offer.
- The parcel list posts on the county's "Properties Available for Sale" page roughly three months before the sale, and the same page is reused for post-sale results, so an empty or results-only page means the next list has not gone up yet.
- Office hours are Monday through Friday, 8 AM to 5 PM. General questions go to (805) 781-5831.
California statewide rules
- Redemption
- Tax-defaulted property may be redeemed until the right of redemption is terminated (section 4101). That right terminates at the close of business on the last business day prior to the commencement date of the tax sale, and the start of the auction counts as the sale date no matter when bidding closes. A redemption payment sent by mail must be received in the tax collector's office before that deadline. California has no post-sale redemption period: once the auction opens, a record owner who has not redeemed loses all legal and equitable interest in the property. Two situations revive the right of redemption. The right revives if the property is not sold, and it revives on the next business day if the tax collector approved a credit sale and the buyer did not pay in full by the deadline the tax collector set.
- Deed deposit
- The tax collector may require a deposit and must give public notice before the sale of its amount, payment method, and due date, and of whether it is a condition of bidding or applies toward the purchase price. On a sale the tax collector approves as a deferred-payment transaction, the deposit may be $5,000 or 10 percent of the minimum bid price, whichever is greater. Counties set the specific figure, so confirm it on the county page or auction platform.
- Surplus proceeds
- Sale proceeds first cover statutory distributions, then taxes, assessments, and county costs. Anything left is excess proceeds held in the delinquent tax sale trust fund. A party of interest may file a claim at any time before one year after the tax collector's deed to the purchaser is recorded. Distribution runs first to lienholders of record before the tax deed was recorded, in order of their priority, then to persons with title of record. Excess proceeds not claimed within that year may be transferred to the county general fund.
A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
