Riverside Bkk Zoning Ordinance Amendment Revises Multi-Unit Housing Permits

The Riverside Bkk City Council adopted amendments to the Municipal Zoning Ordinance on 2 July 2026 that alter density allowances and review timelines for multi-unit residential projects. The updates apply to parcels zoned R-2 and R-3 within the municipal boundaries and require new documentation for projects exceeding four units.

Local government records show the amendments respond to housing permit backlogs documented in the 2025 annual planning report. The changes arrive as the city processes applications under the existing five-year development framework adopted in 2024.

Permit Process Adjustments for Property Owners

Under the revised rules, applicants must submit traffic impact statements for any proposal adding more than six units on a single lot. Property owners in the Riverside East and West districts will file these statements with the Department of Planning and Zoning before receiving preliminary approval. The legislation states that review periods will extend from 45 days to 60 days for affected submissions.

Renters in buildings that receive new permits may encounter updated lease terms once construction concludes. Local advocates note that existing tenants remain protected under current rent-stabilization provisions until their contracts expire.

Budget Allocation and Next Steps

The 2026 Municipal Budget Paper allocates 1.8 million baht to hire two additional zoning reviewers to handle the revised workload. City staff will begin accepting updated application forms on 15 July 2026. The government says the policy will clear 120 pending cases by December 2026.

Residents seeking to convert single-family homes into duplexes must now attend a mandatory neighborhood notification meeting before filing. Further guidance will be posted on the city website by the end of July.
