Senate Bill 287 Slashes Property Taxes for Riverside Bkk Homeowners, Excludes Renters

Senate Bill 287, enacted by the state legislature on 2 July, revises property assessment formulas for qualifying single-family residences in Riverside Bkk, reducing taxable values by an average of 7 percent for homes meeting size and occupancy criteria. The change applies to parcels recorded with the county assessor before 1 January 2025 and takes effect with the 2027 tax cycle. Local records list 48,300 such properties inside city limits.

The legislation follows the state revenue department’s 2025 annual report, which documented a 14 percent rise in median assessed values across the Riverside metro area over two years. Officials cited the need to recalibrate formulas after the prior reassessment cycle produced higher bills for long-term residents. The bill does not alter rates for apartment buildings or business properties.

Daily Effects for Riverside Bkk Households

Residents in the Riverside district who own homes of 180 square meters currently pay an average of 3,150 dollars in annual property taxes. Under the new formula those owners are projected to see reductions of 220 dollars per year once the 2027 notices are mailed. Families in the East Riverside neighborhood with properties built before 1990 qualify for the full adjustment, while newer subdivisions on the western edge meet the size limit but must submit occupancy affidavits by 15 September.

Renters in the downtown corridor receive no direct offset. The state housing authority data from March 2026 shows 62 percent of Riverside Bkk rental units sit in buildings assessed under commercial categories, which the bill leaves unchanged. Local advocates note that lease renewals scheduled for 2027 will continue to reflect the higher underlying assessments.

Next Steps and Implementation Timeline

County assessors will begin mailing revised valuation notices in November 2026, with a 30-day window for owners to file correction requests. The state budget office projects 10.4 million dollars in total relief distributed to Riverside Bkk residential parcels during the first year of operation. Commercial property owners and owners of buildings containing five or more units remain outside the scope of the adjustment.

Training sessions for local tax staff start next month at the county administration building, covering updated calculation software released by the state revenue department. Residents can check eligibility through the county online portal using their parcel number once the system update is complete in October.
