Thonglor District Referendum on Infrastructure Levy: Effects on Local Road Repairs and Household Fees
Thonglor residents face a October ballot measure that would raise the annual property service charge by 180 baht to cover additional street resurfacing and drainage work in the Sukhumvit 55 corridor.
How we reported this
The Thonglor District Office placed a referendum question on the October 2026 ballot that would authorise an infrastructure levy collected through existing property service bills. The measure applies to all rateable properties within the district boundaries and targets funding for road resurfacing and drainage upgrades along Thonglor Road and adjacent sois.
The Bangkok Metropolitan Administration approved the referendum format in its June 2026 session after the district received repeated complaints about flooding during the 2025 monsoon season. District records show 312 flooding reports filed between May and October last year, mostly from sois off Sukhumvit 55. The legislation states that any funds raised must be spent within Thonglor and cannot be transferred to other districts.
Daily costs and service changes for residents
Under the proposal the annual property service charge would rise from 2,400 baht to 2,580 baht for the average condominium unit. Local advocates note that this amount appears on the same bill residents already receive each January. The extra revenue is projected to support resurfacing of 4.2 kilometres of local roads per year, beginning with sections near Thonglor BTS station where potholes have forced temporary lane closures three times since January.
Policy analysts say the levy would also pay for additional drainage inspection crews that currently operate only during declared flood alerts. Community voices at the June public hearing emphasised that improved drainage would reduce the need for private sandbag purchases, which one soi resident estimated at 800 baht per heavy rain event. The draft by-law requires annual publication of spending details on the district website within 60 days of the financial year close.
Next steps after the vote
If approved, the first levy collection would begin with the January 2027 billing cycle. The district office has scheduled three information sessions at the Thonglor community hall on 15, 22 and 29 July to explain the exact wording on the ballot paper. The legislation requires a simple majority of valid votes cast for the measure to take effect, with results certified by the Bangkok Election Commission within seven days.
