Body of News Release
Marin County, CA – Marin County Assessor-Recorder-County Clerk Shelly Scott has completed and certified the 2026 local Assessment Roll, which totals $114.1 billion. The assessment roll increased 3.62% over the previous year, reflecting approximately $4 billion in additional assessed property value.
The annual Assessment Roll establishes the taxable value of residential and commercial real estate, boats, aircraft, business property, and other taxable property throughout Marin County. Property tax revenue generated from the Assessment Roll provides critical funding for public schools, public safety, fire protection, parks, libraries, transportation, and other local government services.
Although the pace of growth slowed from recent years, Marin's property market remained resilient during 2025. New construction, property transfers, and the annual Proposition 13 inflation adjustment continued to drive growth in assessed values. In June 2025, the countywide Assessment Roll was $110.1 billion.
"The 2026 Assessment Roll reflects a stable Marin County real estate market and continued investment in our communities, even as higher interest rates and affordability challenges influenced market activity," Scott said. "Our office is committed to delivering fair, accurate assessments that ensure taxpayers are treated equitably and local governments have a reliable foundation for funding the essential services our communities depend on."
Property Tax Savings
In addition to Proposition 13's limits on annual increases in assessed value, California offers property tax relief programs for qualifying property owners. This year, more than $3.77 billion in assessed value was exempted from the Marin County Assessment Roll.
Homeowners who own and occupy their home may qualify for the homeowners’ exemption, which reduces a home's assessed value by $7,000. Additional exemptions are available for qualified disabled veterans and certain nonprofit organizations.
Change in Assessed Value Notification
Marin property owners were notified by mail in June if the assessed value of their property changed for reasons other than the annual California Consumer Price Index adjustment. Assessed value changes may be due to new ownership, new construction, market value changes, or other factors.
