The San Bernardino County Assessor's office in San Bernardino values every property on California's January 1 lien date. When that assessed value overshoots the market, you have two tools: an informal Prop 8 decline in value review with the assessor, or a formal Assessment Appeals Board filing with the Clerk of the Board.

San Bernardino County reminder: California's Prop 13 caps annual taxable value growth at 2%, so a successful appeal keeps paying dividends every year your market value sits below the Prop 13 base. Prop 8 is the complement. It lets you capture temporary market dips. Both paths run through the San Bernardino County Assessor in San Bernardino.

When does San Bernardino County mail assessment notices?
California counties, including San Bernardino, typically mail notices in June or July. Your window to file BOE-305-AH opens July 2 and closes either September 15 or November 30 depending on the county's Clerk of the Board schedule. Confirm with the San Bernardino Clerk's office.
Do I have to use an attorney?
No. The California Assessment Appeals Board is designed for pro se homeowners. Filing BOE-305-AH is a two page form and hearings are informal. Most San Bernardino County homeowners file and represent themselves.
Will my San Bernardino County taxes go up if I appeal?
No. California appeal outcomes at the Assessment Appeals Board are strictly reductions or no change. Prop 13 caps assessed value growth at 2% per year regardless.
Is Prop 8 the same as Prop 13?
No. Prop 13 is the base year rule that caps annual assessment growth. Prop 8 is the companion rule that lets the assessor (or you) temporarily drop your value below the Prop 13 base when the market falls. When the market recovers, your value can rise back up to the Prop 13 cap, but not above it.
