Property Tax Grievances in Genesee County, New York
Genesee County Real Property Tax Services supports municipalities, processes assessment rolls, maintains maps, and publishes property information, while the responsible city or town assessor and Board hear the grievance. The exact filing calendar must be confirmed with the applicable local assessor. The FairPath owner-guided packet remains available year-round to organize the roll, PROS record, owner-approved corrections, comparisons, condition evidence, calculations, and official source notes. FairPath does not file RP-524, choose the homeowner's value or requested assessment, contact the assessor or Board, represent the owner, or predict an assessment change, tax savings, tax bill, hearing result, or outcome.
Assessment context: Begin with the tentative roll and Genesee County PROS record, identifying municipality, SWIS code, tax-map parcel, class, exemptions, assessed value, uniform percentage, valuation date, acreage, and inventory. PROS provides property information, inventory, and comparable-sale search, but the municipal roll remains the assessment authority. The City of Batavia and Town of Batavia are separate assessing units despite the shared name and mailing geography. Batavia urban neighborhoods, Le Roy and village property, agricultural land, rural acreage, manufactured homes, industrial uses, wells, septic systems, and corridor development are not interchangeable. Normalize assessment comparisons using the correct municipal percentage and verify property facts with the local assessor before relying on an apparent mismatch.
Filing process: New York generally uses Form RP-524 for this local administrative grievance. Use the county assessor directory and current tentative roll to identify the actual city or town office, then verify tentative-roll date, assessor sitting dates, Grievance Day, Board hours, filing address, required copies, appointment policy, and accepted delivery method. Do not use City of Batavia instructions for a Town of Batavia parcel or the reverse. The homeowner supplies the grounds, value estimate, requested assessment, supporting facts, and signature. Preserve the complete form, roll and PROS pages, proof of delivery, exhibits, and Board determination. Later SCAR or Article 7 review has distinct eligibility, fees, and deadlines that FairPath does not select or file.
Evidence to review: Anchor the packet to the municipal roll and PROS property inventory. Document measurable errors in acreage, living area, units, basement finish, garage, barns, outbuildings, agricultural use, class, exemptions, utilities, additions, or legal use. Select arm's-length sales or assessment records from the same assessing unit and relevant submarket, then explain differences in city, village, or rural setting, farm influence, acreage utility, water and septic, property type, effective age, renovation, industrial proximity, and condition. Dated photographs, surveys, permits, inspections, appraisals, farm records, environmental information, and contractor scopes can establish facts. Repair cost is not an automatic dollar-for-dollar value adjustment. Owner-provided facts remain attributed and require homeowner approval before packet inclusion.
Current deadline guidance: The filing date is assessing-unit specific; verify the current city or town calendar. New York states that specific assessment-cycle dates vary by locality and directs owners to confirm the exact dates with the local assessor. In Genesee County, the City of Batavia or the applicable town controls the tentative roll, Grievance Day, Board hours, and receipt instructions. The City and Town of Batavia are separate assessing units, so no countywide date should be inferred.
Genesee County combines Treasurer and Real Property functions while local city and town assessors retain assessment and grievance authority. Preserve the municipality, SWIS code, roll version, valuation date, assessment percentage, and PROS retrieval date so evidence stays reproducible.
City of Batavia and Town of Batavia are separate assessing units and cannot share filing instructions by name alone.
PROS offers inventory and comparable-sale search, but the current municipal roll and assessor remain authoritative for the assessment.
Urban Batavia, villages, farms, rural acreage, manufactured housing, industrial property, wells, and septic systems require different controls.
