Mono County Property Tax Rates

Mono County property tax rates follow California’s Proposition 13 framework, which caps the general ad valorem tax at 1 percent of assessed value plus voter-approved bonded debt and special district assessments. The base rate applies uniformly across all properties within the county’s boundaries, with local additions reflecting community facilities districts, Mello-Roos obligations, and school bonds.

Total tax bills combine the base 1 percent rate, local voter-approved rates for schools and infrastructure, and any parcel taxes or special taxes approved by registered voters in the district.

• Basic levy cannot exceed 1 percent of assessed valuation
• Annual assessment increases capped at 2 percent per year
• Property reappraised only at sale or new construction completion
• Voter-approved bonds appear as separate line items on tax bills
• Special districts fund fire protection, water, and lighting services

Property Tax Assessment Process in Mono County

The Mono County Assessor’s Office establishes the assessed value for each parcel as of the January 1 lien date each year. Assessors apply the Proposition 13 base year value adjusted by the annual inflation factor, plus any new construction assessed at market value.

Three valuation approaches guide assessed values under California law: the sales comparison approach, the cost approach, and the income approach for commercial and rental properties.

1. January 1 acts as the statutory lien date for the tax year
2. Assessors identify ownership changes recorded with the Clerk-Recorder
3. Market data is gathered from recorded sales within Mono County
4. Base year values are adjusted using the California Consumer Price Index
5. New construction permits trigger supplemental assessments
6. Notices of Assessed Value are mailed by August 1 each year
