Frequently Asked Questions
How do I appeal my San Bernardino County property tax assessment?
The formal appeal window runs July 2 through December 1 each year. San Bernardino County charges a $45 nonrefundable filing fee per application — fee waivers are available for qualifying residents. File with the Assessment Appeals Division at 385 N Arrowhead Ave, 2nd Floor, San Bernardino. Before filing formally, contact the Assessor's Office at 909-387-8307 for an informal review. Ownwell can manage the entire process and only charges if you save.
Why does San Bernardino County have four Assessment Appeals Boards?
San Bernardino County has four Assessment Appeals Boards to handle the volume of appeals generated by the county's large and geographically dispersed property base. Each board has three citizen members appointed by the Board of Supervisors. Having multiple boards allows the county to schedule and hear more cases simultaneously and serve residents across its 20,105-square-mile territory more efficiently.
Where do I file probate in San Bernardino County?
Probate matters are handled at the Fontana District courthouse (17780 Arrow Blvd, Fontana) and the Victorville District courthouse (14455 Civic Dr, Victorville) — not at the main San Bernardino courthouse downtown. Which location you use depends on where the deceased resided. Contact the probate clerk before filing to confirm the correct courthouse. Probate notes are available through the Court Access Portal two weeks before your hearing.
How do I find the right courthouse in San Bernardino County?
San Bernardino County has six courthouse locations serving distinct geographic regions. The main Justice Center at 247 W 3rd St in San Bernardino handles central county matters. Rancho Cucamonga serves the western Inland Empire. Fontana serves the Fontana and Rialto area. Victorville serves the High Desert. Big Bear Lake serves mountain communities. Barstow serves the Barstow area. Filing in the wrong district can result in transfer delays. When in doubt, call the court clerk before traveling.
