Property Tax Appeals in Glenn County, California
Glenn County's Clerk of the Board of Supervisors page states that the office provides overall support to the Board of Supervisors and acts as Clerk for other boards, including the Board of Equalization, Air Pollution Control District, and Assessment Appeals, rather than printing the regular-roll filing window as page text. The California State Board of Equalization's certified 2026 filing-period table lists Glenn County's regular filing period as ending November 30, 2026. Neither the Clerk of the Board's page nor the Assessor's Office page states a dollar filing fee for the Assessment Appeal Application. The Clerk of the Board's office is listed at 525 West Sycamore Street, Suite B1, Willows, CA 95988, phone 530-934-6400. FairPath can help an owner organize a comparison table, condition photos, official links, and a filing checklist. It does not file the application, choose the owner's opinion of value, or communicate with the Assessor's Office or the Board on the owner's behalf.
Assessment context: Begin with the Assessor's parcel record and confirm the current regular-roll filing dates directly with the Clerk of the Board, since Glenn County's own Clerk of the Board page does not print fixed dates as page text. Glenn County sits in the northern Sacramento Valley, anchored by the county seat of Willows and the agricultural communities of Orland and Hamilton City, with rice fields and orchards spreading across the valley floor and the Coast Range foothills of the Mendocino National Forest rising along the county's western edge near Stony Creek. A property a few miles away can sit in a very different irrigated-farmland, orchard, or foothill-rangeland setting, so land use and water rights should be confirmed against the Assessor's record rather than assumed from a map.
Filing process: Glenn County's Clerk of the Board of Supervisors page lists the Assessment Appeal Application among its resources, with the Clerk of the Board's office at 525 West Sycamore Street, Suite B1, Willows, CA 95988, phone 530-934-6400, serving as the filing point since the Clerk acts for the Board of Equalization and Assessment Appeals. The Assessor's Office, at 516 West Sycamore Street (Courthouse Annex), Willows, CA 95988, phone 530-934-6402, maintains the parcel record, maps, and ownership information an owner would review before filing. Neither page describes an online e-filing system separate from the posted application, and neither states a dollar filing fee for the Assessment Appeal Application.
Evidence to review: Glenn County's Clerk of the Board page links to a separate Assessment Appeal Publication 30 resource for background on the appeals process, rather than describing evidence rules directly on the page itself. Build a comparable-sales table showing sale date, price, parcel, community, lot size, living area, age, and condition, weighted toward sales near the January 1, 2026 lien date, since California law generally excludes comparable sales occurring more than 90 days after that date. For rice, orchard, or foothill-rangeland parcels around Orland, Hamilton City, or the Stony Creek area, document acreage, water rights, and any condition issues with dated photographs, since land use varies widely across Glenn County's valley-to-foothill geography.
Current deadline guidance: 2026 regular assessment appeals: filing period ends November 30, 2026; the county directs owners to the Clerk of the Board of Supervisors for the current filing period. The Board of Equalization lists Glenn among the counties whose 2026 regular filing period ends November 30, 2026; file with the Glenn County Clerk of the Board of Supervisors, which its own page states acts as Clerk for the Board of Equalization and Assessment Appeals, as its page describes. The Clerk of the Board's page does not itself print the regular-roll date range.
