How much are condominium common fees in Thailand in 2026?

The Condominium Act requires owners to share common expenses in proportion to each unit's registered area unless the bylaws set a different lawful formula. Your monthly invoice is usually quoted as baht per square metre of your unit, multiplied by your registered size.

Older low-rise projects in Chiang Mai or outer Bangkok might sit near the lower end of the range. High-rise towers with pools, gyms, and 24-hour security in Sukhumvit, Thonglor, or Phuket west coast often land higher. Luxury branded residences can exceed the rough 40 to 100 baht per sqm band entirely. Always request the current schedule from management, not a year-old listing screenshot.

Renters sometimes pay common fees through the landlord as part of "all inclusive" rent, or separately if the lease says so. Clarify that split before you sign, using rental contracts and deposits as a checklist alongside how to rent a home.

Beyond the monthly line item, owners usually contribute to a sinking fund (a reserve for major capital works such as facade repainting, lift replacement, or waterproofing). Amounts vary by age and ambition of the building.

When the reserve is too small, the juristic person may levy a special assessment, a one-off charge voted at an owners' meeting. A cheap purchase price or low advertised rent can turn expensive after a roof vote. Review meeting minutes, audited accounts, and any pending projects before you buy foreign-quota stock under can foreigners buy property.

Unpaid common fees attach to the unit. At transfer, buyers are often expected to clear seller arrears or negotiate who pays. That cleanup belongs in your property purchase costs spreadsheet alongside transfer fees.

Bangkok mid-rise and supertall projects on the BTS corridor usually carry heavier staffing and lift costs than a walk-up in Ayutthaya. Resort condos in Pattaya or Samui may bundle extensive pool and garden upkeep. If you are narrowing neighbourhoods, compare real out-the-door housing cost in Living in Bangkok with fee-inclusive quotes, not headline rent alone.

Ownership structure still matters: only registered condominium freehold within quota carries this juristic person framework. Land-backed villas use different cost lines, which freehold versus leasehold explains.
