Chiang Mai Condo Service Charges (2026)
What a Chiang Mai condominium charges you to run it
The common-area fee is the cost buyers most reliably underestimate, because it is quoted per square metre per month and therefore looks small until it is annualised against a unit that may be empty for part of the year.
How it is calculated
Per square metre, per month, on the registered area of the unit. Roughly ฿40 to ฿70 per m² is typical across Thailand, so a 35 m² unit runs a few thousand baht a month and a 70 m² unit runs double. It scales with SIZE, not with price, which is why a large cheap unit can carry a heavier running cost than a small expensive one.
The sinking fund is a separate thing
A contribution toward major works — lifts, structure, the things that arrive once a decade and cost more than a year of fees. A building with a thin sinking fund is not cheaper to own, it is deferring a bill. How that failure actually looks.
What to ask before you offer
The current rate per m², when it last rose, the sinking-fund balance, and whether any major works are scheduled. A juristic office that cannot answer those four questions quickly is itself the answer.
// The building file
Area medians tell you where to look. The Chiang Mai Condo Buyer’s Guide names the buildings inside those areas, each with its unit count, size range and the rent evidence behind it.

Are these asking prices or achieved prices?
Asking. They are what the market is currently testing, computed as the median per area from the building file. Achieved prices sit below asking and are not published by any Thai portal.
Can a foreigner buy a condominium in Chiang Mai?
Yes, on freehold title inside the building's 49 percent foreign quota, in their own name. Land is closed to foreign individuals.
How is the common-area fee calculated?
Per square metre of the registered unit area, per month, so it scales with size rather than price. Roughly 40 to 70 baht per square metre is typical.
What is the sinking fund?
A separate contribution toward major works. A building with a thin sinking fund is not cheaper to own, it is deferring a bill.
