How to Search San Diego Property Tax Records
The fastest lookup uses the 10-digit APN, formatted as book-page-parcel (000-000-00-00). Your APN appears on the most recent tax bill or grant deed. The Treasurer-Tax Collector’s search tool accepts either the APN or the street address and returns the current fiscal year’s tax data, payment status, and any outstanding balances.1San Diego County Treasurer-Tax Collector.

What Appears in a Property Tax Record
Each record ties together the APN, the street address, and the legal owner as shown on the most recent deed. The assessed value is broken into two components: the land and any improvements such as buildings or landscaping. California’s constitution caps the base property tax rate at 1% of full cash value, so a home assessed at $800,000 owes $8,000 in base taxes before anything else is added.3Justia Law. California Constitution Article XIII A Section 1 – Tax Limitation Under Proposition 13, that assessed value generally increases no more than 2% per year unless the property changes hands or undergoes new construction.
On top of the 1% base, the record shows voter-approved debt service and special assessments. Mello-Roos charges are common in newer San Diego developments and fund infrastructure such as roads, schools, and fire stations. You can identify the specific Community Facilities Districts attached to a parcel on the County’s Special Assessments page, which lists each district by name with a contact phone number.4County of San Diego. Mello-Roos These charges can add thousands of dollars to an annual bill, so buyers should check them before closing.
The record also reflects exemptions that reduce taxable value. The Homeowners’ Exemption knocks $7,000 off the assessed value of a primary residence, saving roughly $70 per year.5California Department of Tax and Fee Administration. Homeowners Exemption Disabled veterans with a 100% VA disability rating qualify for a larger exemption on a primary residence; the basic tier applies regardless of income and requires a one-time filing, while the low-income tier requires annual renewal by February 15.6San Diego County Assessor/Recorder/County Clerk.

Payment Status, Due Dates, and Penalties
The record shows whether each installment for the current fiscal year has been paid. Annual taxes are split into two installments: the first is due November 1 and delinquent after December 10, and the second is due February 1 and delinquent after April 10.7San Diego County Treasurer-Tax Collector.

Supplemental Bills May Not Appear on the Regular Record
When a property changes ownership or new construction is completed, the county reassesses the property and issues a supplemental tax bill for the difference between the old and new assessed values, prorated from the date of the change through the end of the fiscal year on June 30.10San Diego County Treasurer-Tax Collector. Supplemental Property Taxes Subtract the old assessed value from the new one, prorate by months remaining in the fiscal year, and apply the 1% rate.
A supplemental bill arrives separately from the regular annual bill, sometimes months after closing, so a buyer looking at the regular tax record shortly after a sale may not see the supplemental amount yet. If the new assessed value is lower than the previous one, the county issues a supplemental refund instead.
When Records Show a Tax-Defaulted Property
If both installments remain unpaid by June 30, the property is declared tax-defaulted. Redemption penalties then accrue at 1.5% per month on the unpaid amount, which reaches 18% after one year and continues compounding on any additional taxes that come due.
After five years in default, the tax collector gains legal authority to sell the property at public auction to recover the unpaid taxes.11California Legislative Information. California Revenue and Taxation Code 3691 For nonresidential commercial property, the timeline is three years. The county must publish notice of the sale in a newspaper beforehand. The owner’s right to redeem by paying all back taxes, penalties, and fees runs only until the close of business on the last business day before the sale.
If the Record Shows the Wrong Value
Two separate processes exist for owners who believe the assessed value on the record is too high. Start with the informal route, which is free and handled directly by the Assessor’s Office. The formal route goes before an independent review board and fits disputes the Assessor will not resolve informally.
Decline-in-Value Review (Proposition 8)
If market value has dropped below the assessed value, you can request a Proposition 8 decline-in-value review at no cost. The application period runs December 1 through April 30, using the “Review of Assessment (Proposition 8)” form available online or at any Assessor branch.12San Diego County Assessor/Recorder/County Clerk. Real Property Assessment If the Assessor agrees, the assessed value is temporarily reduced. The reduction is not permanent; the Assessor reviews it annually and can restore the value as the market recovers.
Formal Assessment Appeal
If you disagree with the Assessor’s determination, file a formal appeal with the Clerk of the Board of Supervisors. The filing window generally runs July 2 through November 30 for regular assessments.13San Diego County Assessor/Recorder/County Clerk. Assessment Appeals For a supplemental assessment, you have 60 days from the mailing date on the supplemental tax bill. The Assessment Appeal Application is available through the County’s Assessment Appeals Board page.14County of San Diego. Property Tax Assessment Appeals
The county schedules a hearing before an independent citizen review board where you present evidence such as comparable sales or an independent appraisal. If you and the Assessor’s Office agree in writing before the hearing, the hearing is waived. Missing the filing deadline means waiting until the next fiscal year.
If the Record Shows the Wrong Mailing Address
To update the mailing address so tax bills reach you, the Assessor’s Office offers an online form for single-property changes. For multiple properties, download and submit a “Change of Address – Real Property” form by mail, email to addr.arcc@sdcounty.ca.gov, or in person at any branch office with a valid photo ID.15San Diego County Assessor/Recorder/County Clerk. Address Change Request If the property is held in a trust or company name, only the owner on title or an authorized agent can file the change. A bill sent to an old address does not extend any deadline; penalties apply whether or not the bill reached you.
