Alameda County, California — Tax Sale & Surplus Procedure
Local operations layer. The legal framework (5-year power-of-sale clock, pre-sale-only redemption, RTC §§ 4674–4676 excess-proceeds waterfall, Tyler compliance, statutes, case law) lives on the parent page → california. This page covers how Alameda County actually runs it. Legal information, not legal advice. Last verified: 2026-06-01.
C0. Identity
- County seat: Oakland · Population: 1,682,353 (2020 Census; 7th-most-populous CA county). City of Oakland 440,646 (2020). — https://www.census.gov/quickfacts/fact/table/alamedacountycalifornia,oaklandcitycalifornia,US/POP010210
- Recording unit: county (one of California’s 58 counties)
- FIPS: 06001
- Selling authority: Alameda County Treasurer-Tax Collector (TTC) — exercises the statutory power of sale under RTC authority (see california module 1). The county does not use a sheriff for tax-defaulted sales. — https://treasurer.acgov.org/tax-defaulted-land/
- Parent legal framework: california
C1. Local Tax Sale
- Conducts own sale? Yes — the TTC offers tax-defaulted property (taxes unpaid five years or more) at public auction; the county sells to the highest bidder online (no courthouse-steps sale). There are no tax-lien certificates and no over-the-counter sales — these are no-reserve online auctions and properties sell “as is.” — https://treasurer.acgov.org/tax-defaulted-land/ , https://treasurer.acgov.org/tax-defaulted-land-faqs/
- Platform / vendor: Bid4Assets (online auction). Bid4Assets handles all registration, deposits, and bidding; bidder support 1-877-427-7387. 2026 county storefront: https://www.bid4assets.com/storefront/AlamedaMar26 (HTTP 403 to automated fetch; storefront name + sale terms corroborated via the county TTC FAQ and KTVU news coverage below). — https://treasurer.acgov.org/tax-defaulted-land-faqs/
- Calendar / frequency: Annual online tax sale, customarily held in late March (re-offer sales of unsold parcels have occurred in May in prior years, e.g., AlamedaMay21 / AlamedaMay22Reoffer / AlamedaMay23Reoffer storefronts). — https://treasurer.acgov.org/tax-defaulted-land/
- 2026 annual tax sale: 256 tax-defaulted properties offered, opening bids as low as **1.5M). Deposit deadline: Tue. Mar 17, 2026, 1:00 p.m. PT (4:00 p.m. ET). Auction opens: Fri. Mar 20, 2026, 8:30 a.m.; closes Wed. Mar 25, 2026 (closing times vary by parcel). Full payment/settlement due by Mar 25, 2026, 1:00 p.m. PT (4:00 p.m. ET). — https://www.ktvu.com/news/deadline-looms-property-auctioned-bay-area-county-bids-low-455 (KTVU FOX 2, quoting Bid4Assets marketing manager Sean McLaughlin)
- Rate within statutory range: N/A — California is a tax-deed state with no investor interest/bid-down mechanism; the minimum bid is the redemption amount + costs (see below and california).
- Registration / deposit: Register on Bid4Assets (free account); bidders must complete vesting information before they can access deposit instructions. A single refundable 35 processing fee ($5,035 total) is required, received by Bid4Assets no later than the deposit deadline. The deposit is applied to the winning bid or refunded if the bidder wins nothing. — https://treasurer.acgov.org/tax-defaulted-land-faqs/ , https://www.ktvu.com/news/deadline-looms-property-auctioned-bay-area-county-bids-low-455
- Bidder requirements / payment terms: Bids placed by Auction ID at predetermined increments until close; proxy bidding available for bidders without internet access. Minimum bid = total amount to redeem the delinquent taxes plus costs (RTC § 3698.5; see california). Winning bidders must submit deed-vesting/transfer information to Bid4Assets within 24 hours of close and pay the balance by the settlement deadline; only certified check/money order or wire transfer are accepted (ACH, credit card, money transfers rejected). All sales are final, no refunds; failure to pay forfeits the deposit to Alameda County and may result in a ban from future sales. — https://treasurer.acgov.org/tax-defaulted-land-faqs/ , https://www.ktvu.com/news/deadline-looms-property-auctioned-bay-area-county-bids-low-455
- Delinquent / sale list location: Parcel preview list published on Bid4Assets for the specific sale (e.g., the AlamedaMar26 storefront), updated daily as parcels are redeemed before the auction; the TTC links to it from its Tax Defaulted Land page. County Assessor plat maps are recommended to locate parcels. — https://treasurer.acgov.org/tax-defaulted-land-faqs/ , https://treasurer.acgov.org/tax-defaulted-land/
C2. Local Redemption → framework: right-of-redemption
- Where/how to redeem: Pay all defaulted taxes, penalties, interest, and costs to the Treasurer-Tax Collector before the pre-sale cutoff. Per the TTC FAQ, the right to redeem expires at the close of business, 5:00 p.m., on the last business day prior to the sale — a local restatement of the state rule (RTC § 3707; see california and right-of-redemption). — https://treasurer.acgov.org/tax-defaulted-land-faqs/
- Local fees: State-set redemption charges apply (10% delinquent penalty + 1½%/month redemption penalty + $15 redemption fee — see california module 2); no Alameda-specific local redemption surcharge located.
- Redemption contact: Treasurer-Tax Collector, (510) 272-6800; TTC.WEBMAIL@co.alameda.ca.us; office at 1221 Oak Street, Room 131, Oakland, CA 94612. — https://treasurer.acgov.org/tax-defaulted-land/ , https://treasurer.acgov.org/tax-defaulted-land-faqs/
- Deviations from state default: none identified — Alameda follows the California pre-sale-only redemption rule with no post-sale redemption of a tax deed.
C3. Local Surplus / Excess Proceeds → framework: surplus-funds
- Claim filing venue: Clerk of the Board’s Office, Assessment Appeals Unit, Attn: Claim for Excess Proceeds — i.e., the Clerk of the Board of Supervisors, NOT the Tax Collector and NOT a court. Mailing/filing address: 1221 Oak Street, Suite 536, Oakland, CA 94612. Phone (510) 272-3854, Fax (510) 208-9660. (This is the office that determines the proof required and brings claims to the Board for distribution under RTC § 4675(d)–(e); see california module 3.) — https://www.acgov.org/clerk/forms/claimexcess.pdf
- Claim form: “Claim for Excess Proceeds (Revenue & Taxation Code § 4675)” — official Clerk of the Board form. https://www.acgov.org/clerk/forms/claimexcess.pdf (also listed on the Clerk’s forms page https://www.acgov.org/clerk/forms.htm). The form requires the Assessor’s Parcel No., Item No., Date of Sale, amount claimed, a notarized declaration under penalty of perjury, and a statement of the claimant’s party-of-interest basis. — https://www.acgov.org/clerk/forms/claimexcess.pdf
- Documentation required (per the form’s instructions):
- Person with title of record: original recorded documents (deed, death certificate, court order, etc.), notarized verification, and photographic proof of identity. Heirs of a deceased title-holder must add a Probate Code § 13100 et seq. affidavit.
- Lienholders of record: original recorded lien + statement of original amount, payments received, and balance due as of the sale date + photo ID. Trust-deed beneficiaries add the original note, trust deed, and assignments; judgment creditors add a certified copy of the judgment and proof the debtor held record ownership.
- Assignees / third-party recovery agents: a verified, notarized affidavit executed by all parties to the assignment that explicitly states the right to claim excess proceeds is assigned, plus (1) proof the amount and source of excess proceeds was disclosed to the interested party, (2) that the party was advised of the right to file a claim directly with the County at no cost, and (3) the interested party’s contact information (mirrors RTC § 4675(b)–(c); see california module 3 and third-party-recovery-rules).
- Business claims: corporate/LLC/partnership authority docs (Articles, Statement of Information, company resolution, etc.). — https://www.acgov.org/clerk/forms/claimexcess.pdf
- Local deadline notes: State law controls — a claim must be filed prior to the expiration of one year following recordation of the Tax Collector’s deed to the purchaser (RTC § 4675(a)). The form expressly notes excess proceeds will not be distributed before the expiration of one year following execution of the Tax Collector’s deed, and any action to review the Board’s decision must be commenced within 90 days of that decision (RTC § 4675(g)). Claimants must notify the Clerk of the Board of any address change so notice can be given at the end of the one-year period. — https://www.acgov.org/clerk/forms/claimexcess.pdf
- Unclaimed-funds / excess-proceeds list published? needs_verification — a standalone Alameda excess-proceeds / unclaimed-funds list URL on an official county page was not located on this pass (the Clerk of the Board hosts the claim form and the TTC publishes auction results PDFs, but no confirmed live “excess proceeds available to claim” listing was retrieved). The TTC does publish auction results reports (e.g., 2023 TDL auction results PDF). — https://treasurer.acgov.org/wp-content/uploads/2023/06/2023-TDLAuctionResultsReport.pdf
- Contact: Clerk of the Board — Assessment Appeals Unit, (510) 272-3854 (excess-proceeds line on the form) / general Clerk of the Board (510) 208-4949. — https://www.acgov.org/clerk/forms/claimexcess.pdf , https://www.acgov.org/clerk/contactus.htm

Note: For tax-defaulted sales and excess-proceeds claims there is no clerk of court role — claims are decided administratively by the Board of Supervisors via the Clerk of the Board (RTC § 4675; see california). The Superior Court is involved only in quiet-title / set-aside litigation or judicial review of a Board decision.
C5. Local Procedure Notes
- Online-only annual tax-defaulted auction via Bid4Assets, customarily late March, with periodic May re-offer sales of unsold parcels; no lien certificates and no over-the-counter sales (consistent with the California tax-deed framework on california). — https://treasurer.acgov.org/tax-defaulted-land/ , https://treasurer.acgov.org/tax-defaulted-land-faqs/
- Excess-proceeds claims route to the Clerk of the Board (Assessment Appeals Unit), not the Tax Collector — an Alameda-specific operational split worth noting for recovery work: the TTC runs the sale and holds the funds, but the § 4675 claim form is filed with the Clerk of the Board at 1221 Oak St., Suite 536, and the Board of Supervisors orders distribution. — https://www.acgov.org/clerk/forms/claimexcess.pdf
- Strict payment discipline: certified funds/wire only, 72-hour/settlement-deadline window, deed-vesting info within 24 hours; non-payment forfeits the $5,000 deposit and risks a bidding ban. — https://treasurer.acgov.org/tax-defaulted-land-faqs/ , https://www.ktvu.com/news/deadline-looms-property-auctioned-bay-area-county-bids-low-455
- Tax deed timing: the Tax Deed is mailed roughly 60 days after the close of the auction; the former owner retains the one-year statutory window to challenge the sale under California law (see california modules 6–7). — https://treasurer.acgov.org/tax-defaulted-land-faqs/
- No Alameda-specific ordinance deviating from the state surplus/redemption framework was located.

- needs_verification:
- Standalone excess-proceeds / unclaimed-funds list URL — no confirmed live official Alameda County listing of “excess proceeds available to claim” was retrieved this pass; only the claim form (Clerk of the Board) and TTC auction-results PDFs were located. Whether Alameda publishes a per-sale excess-proceeds availability list (and at what URL) is unconfirmed.
- Bid4Assets storefront (AlamedaMar26) is HTTP-403/Cloudflare-gated to automated fetch; the 2026 sale terms were corroborated via the county TTC FAQ and KTVU coverage rather than verbatim storefront text.
- County-wide enterprise GIS open-data viewer URL (beyond the Assessor Parcel Viewer) not separately confirmed.
- Treasurer-Tax Collector officeholder name not pulled from a retrieved official bio page (office identified, individual not).
- The TTC FAQ “72 hours” payment phrasing vs. the 2026 KTVU “Mar 25 1 p.m. settlement” deadline — both retrieved; treat the per-sale Bid4Assets settlement deadline as controlling for a given auction.
