The rules that govern it
Cal. Rev. & Tax. Code §1603: the filing window, and it is strict, The regular appeal period runs July 2 to September 15 in counties where the assessor sends every assessee a value notice by August 1 under §619. Where the county does not, the period extends to November 30. San Diego County has published a July 2 to November 30 window. Confirm the current date with the clerk of the board before relying on it, because a deadline falling on a weekend or holiday rolls. Miss it and you generally wait a year.
Cal. Rev. & Tax. Code §167, and why it does not help commercial owners, This section creates a rebuttable presumption affecting the burden of proof in favour of the taxpayer, but only for an owner-occupied single-family dwelling that is the owner’s principal residence and qualifies for the homeowners’ exemption, and in escape assessment appeals. It does not apply to commercial property. On a commercial appeal the burden is yours, which is exactly why the evidence has to be strong.
Proposition 8 decline in value versus Proposition 13 base year, Two different challenges. A Proposition 13 challenge disputes the base year value set when the property changed hands. A Proposition 8 challenge argues that current market value has fallen below the factored base year value, producing a temporary reduction reviewed annually and restorable as values recover, never above the factored base year value. Most commercial appeals are Proposition 8 appeals.
The lien date is the valuation date, The board is asking what the property was worth on the January 1 lien date for the year under appeal. An appraisal with today’s effective date does not answer that question, and a report that capitalises current income rather than income as of the lien date will not survive the assessor’s review.
What makes a cap rate defensible before a board, Extraction from verified comparable sales, as of the lien date, with the income behind each sale verified rather than assumed. A rate taken from a published survey where real comparables existed invites the assessor to produce their own survey, and the board is then choosing between two assertions rather than weighing evidence.
How it works
- Confirm the filing window with the clerk of the assessment appeals board for the county: the statutory rule turns on whether the assessor sends §619 notices, and dates roll off weekends.
- Obtain the assessor’s record and check it for factual error first. Overstated square footage or improvements that do not exist are the cleanest wins and need no valuation argument.
- Establish the correct valuation date: the January 1 lien date for the year under appeal.
- Reconstruct income and expenses as of the lien date, including a reserve for replacement and a reassessed property tax figure where relevant.
- Extract capitalisation rates from verified comparable sales near the lien date, not from survey data.
- Prepare the report for the board as the audience. It must be followable by someone who is not an appraiser.

Most assignments start with a short call, property type, the purpose of the appraisal, and the deadline you are working against. You get a fixed quote before any engagement, never contingent on the value reached.
Typical commercial fees range $2,000–$4,000. Residential and simpler assignments quote lower. Every engagement is quoted in advance, so the figure is known before work begins.
