Clayton Council Adopts Biennial Property Tax Assessments For 12,400 Homes

The Clayton City Council voted 4-3 on July 7 to shift property tax assessments from a three-year cycle to a two-year cycle. The change applies to all parcels within city limits and matches the frequency already used by four other jurisdictions in the county.

Why the timing of the vote

County records show the last full revaluation occurred in 2023. The new ordinance requires the next assessments to begin in January 2027, with notices mailed by December 2026. The legislation states that assessments must now incorporate sales data from the prior 24 months rather than 36 months.

City budget documents project the shorter cycle will add 2.3 million dollars in revenue for fiscal year 2027. That figure equals an average increase of 147 dollars per residential parcel, according to the finance department projection released with the agenda packet.

Effects on Clayton households and services

Homeowners will receive updated notices every two years instead of three. Renters may see indirect effects if landlords adjust lease rates to cover revised tax liabilities. The additional revenue is earmarked for street maintenance contracts and park irrigation upgrades listed in the 2027 capital plan.

Under the prior schedule, properties sold in 2024 would not have been reassessed until 2026. The new rule closes that gap by one year for any parcel that changes hands after the January 2027 start date. Local advocates note that the adjustment brings Clayton's process into line with the county's four other full-service cities that already operate on two-year cycles.

Implementation will require the assessor’s office to hire two temporary data reviewers for six months in late 2026. The council approved a 185,000-dollar line item for that purpose during the same meeting. The government says the policy will produce more current market values for all future tax rolls.
