SAN BERNARDINO, CA – San Bernardino County Assessor-Recorder Bob Dutton signed and delivered Supplemental Assessment Roll #127 to the County’s Auditor-Controller/Treasurer/Tax Collector. Supplemental Assessment Roll #127 contains a net assessed value of $8,274,968,424.

Notable increases include the city of Ontario with a supplemental total value of $1.9 billion, followed by Fontana at $1 billion, and Rancho Cucamonga at $745 million.

“Increases in supplemental assessed values reflect certain transfers of property or new construction during the mid-fiscal year. Supplemental Assessment Roll #127 showcases increased activity in San Bernardino County’s residential and commercial properties,” said Assessor-Recorder Bob Dutton. “The supplemental roll has been signed and delivered to the Auditor-Controller/Treasurer/Tax Collector.”

State law requires county assessors to reappraise property upon a change in ownership or new construction to identify changes in assessed value that occur in the middle of a fiscal year, whether an increase or decrease. Supplemental assessments are issued on real property such as land, improvements, fixtures and taxable possessory interests, but do not apply to personal property or any property not subject to Proposition 13.

A Supplemental Roll is provided three times a year, in addition to the annual Property Assessment Roll, which will be delivered in July.

Property owners who are assessed will be provided a written notice by mail from the assessor, as required by state law. Individuals wishing to see their personal assessed values may visit: The public can also call the Assessor’s toll-free number at 1-877-885-7654.
