Bangkok Condo Common-Area Fee Comparison

A completed condo can have several fee figures in circulation at once. The launch brochure may show one amount, a resale listing another, while the condominium juristic person is collecting a third. For an owner, the operative figure is the one supported by the building’s current rules or fee notice; older developer material is evidence of what was published at that date, not proof that the same rate still applies.

The recurring common-area fee is kept separate here from a sinking fund and from optional resident services. In several project documents, the sinking fund is a one-time transfer payment calculated per square metre. Housekeeping inside a unit, laundry, catering, private event support and similar on-demand services belong in a different bucket unless the building document explicitly says they are covered by the mandatory fee.

Thailand’s Department of Lands provides the legal framework, not a Bangkok tariff. Its 2026 answers explain that Section 18 shared expenses follow the condominium juristic person’s registered bylaws, while Section 40 covers advance expenses, initial capital and other payments made under the conditions set by a co-owner meeting. The same distinction is why a special levy should not be averaged into the normal monthly rate.

For a resale unit, this distinction becomes concrete. A dated juristic-person fee schedule or registered bylaw change is stronger than a launch brochure; a developer transfer sheet is useful when the building is handing over, and professional property pages are supporting evidence; they are not the final word. The Department of Lands also states that a transfer can be registered only when the unit is clear of Section 18 debt and the latest debt-free certificate is presented.

The project documents below show how far apart published Bangkok condo fees can be without implying a citywide benchmark. AP Thailand’s March 2026 material for GOOD DAY Sukhumvit 93 states THB 36/sq m/month, while the COCO PARC brochure states THB 130/sq m/month plus a THB 1,000/sq m sinking fund. Those are documented building figures, not the lower and upper bounds of the Bangkok market.

The date column matters as much as the number. Sansiri’s June 2026 homeowner articles use THB 50 for NIA BY SANSIRI and THB 55 for THE LINE Vibe; Pruksa’s 2026 transfer promotion for Privacy Parc Taopoon discloses THB 55 and a THB 500/sq m sinking fund. By contrast, Ideo Mobi Sukhumvit 40’s THB 65 rate comes from a page updated in July 2020, and Ideo Q Sukhumvit 36’s THB 85 figure comes from an April 2021 project article. For an operating building, those older figures should be treated as historical or transfer-era terms until the juristic person confirms the current charge.

COCO PARC also illustrates why fee levels cannot be read as a quality ranking. Its residential operation is tied to a Dusit hospitality-service model, including staffed concierge and separate on-demand services. A higher published fee may sit alongside a more service-intensive operating model, while a lower fee says nothing by itself about reserves, future levies or management efficiency.

All rates are shown per sq m per month. The third column identifies the evidence type; none is labelled as a current juristic-person schedule for an operating building, so a resale buyer still needs the building’s fresh document.

A per-square-metre rate does not tell you how the building spends it. GOOD DAY Sukhumvit 93 is marketed with a 20-plus-metre pool, a large fitness room, filtered fresh-air equipment, solar panels serving common areas and a shuttle to the BTS. Ideo Mobi Sukhumvit 40 publishes two pools, fitness space, gardens, 24-hour security and CCTV. Those lists show the operating environment, but they do not allocate the fee line by line.

NIA BY SANSIRI uses a different amenity mix, including lounges, a rooftop garden, exercise areas and a walking track. Noble Recole’s brochure adds a garden, sky fitness, multipurpose areas, pool, steam room, laundry space and EV charging. Similar fee levels can therefore support buildings with materially different common-property layouts and staffing needs.

COCO PARC is more useful as a service-boundary example than as a price benchmark. Dusit’s launch material describes onsite concierge, security and maintenance staff, while laundry, catering, events and other personalised services are offered on demand. The existence of those services does not establish that every on-demand item is included in the mandatory building fee; a buyer needs the current service menu to know where the common fee stops.

This is why facility counts do not translate into management quality. The useful comparison is the mandatory service scope, the building’s reserve arrangements and any separately priced resident services, each supported by the document that governs it.

Using three published rates makes the ownership effect easier to see without pretending they are market quartiles. At THB 36/sq m/month, a 35 sq m unit costs THB 1,260 a month or THB 15,120 a year; 50 sq m costs THB 1,800/21,600; 80 sq m costs THB 2,880/34,560. These calculations assume the confirmed chargeable area is the unit area used by the fee rule.

At THB 65, the same three sizes become THB 2,275/27,300, THB 3,250/39,000 and THB 5,200/62,400 per month/year. At THB 130, they rise to THB 4,550/54,600, THB 6,500/78,000 and THB 10,400/124,800. The rate looks abstract until it is multiplied by the apartment you are actually buying.

A sinking fund should stay outside that recurring calculation. On a 50 sq m unit, a THB 500/sq m fund is THB 25,000 once, THB 600 is THB 30,000, and THB 1,000 is THB 50,000. Converting a one-time fund into a monthly “maintenance cost” would blur two different obligations.

Promotional free-fee periods need the same separation. Privacy Parc Taopoon’s 2026 terms publish a THB 55 rate while granting 12 months of common fees as a promotion, so the underlying tariff is not zero. On a resale, the relevant numbers are the current fee, the amount prepaid by the seller, any arrears and the next amount due after transfer.

Online project pages can outlive the commercial terms they were written for. Ideo Mobi Sukhumvit 40 is a clear example: its official page still displays the 2020 transfer terms of THB 65/sq m/month, one year payable in advance and a THB 600/sq m sinking fund. That is valuable historical evidence, but it is not a substitute for the building’s current 2026 collection notice.

The Department of Lands explains why a fee can change without treating the change as arbitrary. Section 18 expense proportions sit in the condominium bylaws, and amendments to those registered rules require the relevant co-owner meeting process; its April 2026 answer also points to Section 40 for advance expenses, initial capital and other payments made under meeting resolutions. A special assessment therefore needs its own basis and date instead of being silently folded into the ordinary monthly rate.

The practical question is always “current as of when?”. A launch tariff remains useful for historical comparison, and an expired free-fee campaign can explain what the first buyer received. Neither tells a resale buyer what the juristic person is charging now.
