Bishop property taxes. A rising market. A narrower opening.

By Vulorean · Published October 4, 2026

The typical home in Bishop, in Mono County, was worth about $574,000 in January 2026, 3.1% more than a year earlier. In a rising market most assessments stay below market value, so an appeal makes sense for specific homes, often ones bought near a past high, rather than whole neighborhoods.

What Bishop home values did

Bishop values were at their high in January 2026. Across Mono County, the typical value was 3.9% below its own peak at the same point, so Bishop saw a smaller drop than the county as a whole.

Values have recovered 3.6% since January, through August 2026. That doesn't weaken a 2026 claim, which is judged as of January 1, 2026, but it may narrow any gap on the 2027 roll.

Which Bishop owners may be over-assessed

Under Prop 13, your assessment starts at your purchase price and can rise up to 2% a year. Under Prop 8, it must drop to market value whenever market value as of January 1 is lower. The table compares a typical purchase in each year with the January 2026 typical value of $574,000.

The buyers most likely to be over-assessed are those who bought in 2022. A typical 2022 purchase would carry a 2026 assessment of roughly $589,000 after the 2% annual increases, about $15,000 more than the January 2026 typical value. At California's 1% base tax rate, that's on the order of $150 a year before local voter-approved add-ons.

This is an illustration built on citywide typical values, not an estimate of your home. Your assessment notice shows your actual assessed value, and some assessors lower values on their own in a falling market, so check it first. If you do appeal, your evidence has to show your home's market value.

Mono County deadlines

• 2026 regular filing period: closed September 15, 2026. Mono County uses the earlier California window.
• Next regular filing period: July 2 through September 15, 2027, for the 2027 roll.
• Before then: ask the Mono County Assessor how and when it accepts informal decline-in-value review requests for 2027. An informal review never extends the formal deadline.
• Supplemental or escape assessments: these have their own deadline, generally 60 days from the notice date. Check the notice.

Where Bishop owners file

Bishop assessments are set by the Mono County Assessor. Formal appeals go to the county's assessment appeals board, not to the city.

Confirm the current form, fee and address with the county before you file. The Mono County guide lists step-by-step instructions and official links.

Building a Bishop case

Market averages explain why an appeal might work. The board decides on evidence about one property. Look for sales of similar homes in Bishop that closed near January 1, 2026. The BOE treats comparable sales as the strongest evidence for a home, and the appeals board can't consider sales more than 90 days after the valuation date. Match living area, age, condition, lot and location as closely as you can, and write down every difference you can't adjust for.

Smaller communities can have few sales in any month. If nearby Bishop sales are thin, widen the search area before you widen the date range, and explain why each sale still compares.

A Vulorean report pulls comparable sales and a January 1 value opinion into one document you can file with. Eligible self-file reports are free during launch, with no payment card required. Review every comparison before you use it; you know your home's condition better than any dataset.
