Bangkok Condo Common Area Fees in 2026: What Investors Need to Know

A Bangkok condo priced at 3.5 million THB (roughly 100,000 USD) carries a monthly common area fee of 2,500 to 7,000 THB. This is the expense that most international investors overlook in their ROI calculations - and it can quietly erode net rental yield by up to 2.5 percentage points per year.

Known in Thai as ค่าส่วนกลาง and referenced in purchase documents as the 'common area fee' or 'CAM fee,' this charge covers pool maintenance, 24/7 security, elevator servicing, lobby upkeep, landscaping, and contributions to the building's sinking fund. It is calculated per square metre, so unit size directly determines the monthly bill.

For serious investors, the critical questions are: how does this cost affect cash flow, and what can you do to account for it properly? Below is a structured breakdown.

Quick answer

• Typical CAM rate in Bangkok 2026: 40 to 120 THB per sqm per month
• Economy segment (On Nut, Bearing): 40-60 THB/sqm - for a 28 sqm studio, that is approximately 1,100 to 1,700 THB per month
• Premium segment (Sukhumvit, Silom, Sathorn): 60-90 THB/sqm - for a 35 sqm one-bedroom, expect 2,100 to 3,150 THB per month
• Luxury segment (Langsuan, Wireless Road, Riverside): 90-150 THB/sqm - for a 45 sqm unit, the bill reaches 4,050 to 6,750 THB
• Sinking fund (one-time payment at purchase): 400-800 THB/sqm, occasionally topped up by a special levy every few years
• Impact on yield: CAM fees reduce gross yield by 1.2 to 2.5 percentage points annually, depending on segment and unit size

Options and scenarios

Scenario 1: 28 sqm studio in the economy segment - Sukhumvit 77 (On Nut)

Purchase price: 2.8 million THB. Long-term rental income: 12,000 THB per month. CAM fee: 50 THB/sqm = 1,400 THB per month.

Annual figures:

• Gross rental income: 144,000 THB
• Annual CAM: 16,800 THB
• Other costs (insurance, minor repairs, withholding tax at 12.5% for non-residents): approximately 22,000 THB

Yield calculation:

• Gross yield: 144,000 / 2,800,000 = 5.14%
• Net yield (after CAM and costs): (144,000 - 16,800 - 22,000) / 2,800,000 = 3.76%
• The CAM fee alone accounts for a 1.38 percentage point drag on returns

Scenario 2: 45 sqm one-bedroom in the premium segment - Asoke / Phrom Phong

Purchase price: 6.5 million THB. Rental income: 25,000 THB per month. CAM fee: 80 THB/sqm = 3,600 THB per month.

Annual figures:

• Gross rental income: 300,000 THB
• Annual CAM: 43,200 THB
• Other costs (property management at 10%, tax, repairs): approximately 48,000 THB

Yield calculation:

• Gross yield: 300,000 / 6,500,000 = 4.62%
• Net yield: (300,000 - 43,200 - 48,000) / 6,500,000 = 3.21%
• CAM fees represent a 1.41 percentage point reduction in annual returns

Scenario 3: 85 sqm two-bedroom luxury unit - Langsuan

Purchase price: 18 million THB. Rental income: 55,000 THB per month. CAM fee: 120 THB/sqm = 10,200 THB per month.

Annual figures:

• Gross rental income: 660,000 THB
• Annual CAM: 122,400 THB
• Other costs: approximately 95,000 THB

Yield calculation:

• Gross yield: 3.67%
• Net yield: (660,000 - 122,400 - 95,000) / 18,000,000 = 2.46%
• CAM fees alone consume over 18.5% of annual rental revenue

At this yield level, the investment thesis depends almost entirely on capital appreciation. Without consistent price growth of 4-6% per year, the numbers do not justify the complexity and currency risk for most investors.

Reference point: Comparable markets

A studio apartment in a major European capital - 30 sqm, purchase price equivalent to 450,000 EUR, monthly rent approximately 1,800 EUR, administrative fees around 150 EUR - delivers a net yield of roughly 4.8 to 5.2% after costs. This is still above Bangkok luxury but broadly in line with the economy segment along the Chao Phraya corridor.

For context, 10-year government bonds in developed markets are currently yielding 4.5 to 5.5% with no currency or liquidity risk. A Bangkok condo investment needs to offer meaningful capital appreciation to justify that premium.

Risks and mistakes

1. CAM rate increases without a statutory cap. Under the Thai Condominium Act (B.E. 2522, amended B.E. 2551), the juristic person (building management committee) can raise CAM rates by ordinary majority vote at the Annual General Meeting. Foreign owners who do not attend the AGM - which is the majority - typically discover the increase when the next invoice arrives. Single-instance increases of 15 to 25% are not uncommon, particularly in buildings aged 8 to 10 years requiring elevator replacement or facade renovation.

2. Delinquent owners creating shortfalls. In buildings where foreign investor ownership exceeds 60%, collective fee arrears are a documented problem. The result is reduced security staffing, pool closures, and general deterioration - all of which suppress rental values and resale prices.

3. Depleted sinking fund. The one-time payment at purchase (400-800 THB/sqm) does not guarantee coverage of future capital works. A special levy of 20,000 to 80,000 THB per unit is a real possibility in older buildings - and rarely appears in investor financial models.

4. Off-plan 'teaser' CAM rates. Some developers advertise an artificially low CAM rate (e.g. 35 THB/sqm) applicable only during the first year of operation. Once building management transfers to the owners' committee, rates revert to market levels. This is a standard marketing technique, not a contractual guarantee.

5. Currency exposure. CAM fees are denominated in Thai Baht. If the Baht strengthens against the investor's home currency (as it did in 2023-2024 for several European currencies), the effective cost of ownership rises even if the nominal THB rate remains unchanged. This exposure compounds across the entire holding period.

6. Comparison with Phnom Penh, Cambodia. Management fees in Cambodian condominiums (notably in BKK1 and Toul Kork districts) run approximately 1.5 to 3.0 USD per sqm per month. For a 50 sqm unit, that is 75 to 150 USD monthly - proportionally similar to Bangkok's premium segment. However, Cambodia's secondary market is significantly less liquid, which complicates exit strategies and should factor into any holding period assumptions.

FAQ

How much are condo common area fees in Bangkok per month?

Typically between 40 and 150 THB per square metre per month. For a 28 sqm studio in the economy segment, expect 1,100 to 1,700 THB. In the luxury segment, an 85 sqm unit can exceed 10,000 THB per month.

What does the CAM fee in a Bangkok condo cover?

The fee covers 24/7 security, pool and gym maintenance, lobby and elevator servicing, CCTV systems, garden upkeep, cleaning of common areas, building insurance, and the salary of the juristic person (management office). Electricity and water inside the individual unit are billed separately.

Can the CAM fee increase over time?

Yes, and there is no statutory maximum under Thai law. An ordinary majority vote at the Annual General Meeting is sufficient to approve an increase. Rises of 10 to 25% in a single year are not uncommon in buildings that are 5 to 8 years old.

What is the sinking fund and how much is it?

The sinking fund is a one-time capital payment collected at the time of purchase to cover future major repairs. The standard rate is 400 to 800 THB per sqm. For a 45 sqm unit, this amounts to 18,000 to 36,000 THB. The owners' committee can vote to collect an additional special levy in the future if the fund is insufficient.

How do CAM fees affect net rental yield?

They reduce net yield by 1.2 to 2.5 percentage points annually. In the luxury segment, CAM fees alone can absorb 18 to 20% of gross rental revenue, making the investment viable only if significant capital appreciation is expected.

Do I have to pay CAM fees if the unit is vacant?

Yes. CAM fees are mandatory regardless of whether the unit is tenanted, owner-occupied, or empty. Arrears attract penalty interest and can restrict the owner's ability to sell the property.

How do Bangkok condo fees compare with Phnom Penh?

Cambodian condo management fees run approximately 1.5 to 3.0 USD per sqm per month - comparable in proportion to Bangkok's premium segment. However, the Cambodian secondary market is considerably less transparent and liquid, which affects resale timelines and exit flexibility.

Do CAM fees include electricity and water?

No. Electricity (supplied via the Metropolitan Electricity Authority) and water are metered and billed separately. Some buildings charge a marked-up unit rate for electricity that can be 30 to 50% above the standard MEA tariff - this should be verified before any purchase commitment.

What due diligence should I conduct on CAM fees before buying?

Request three items from the juristic person: the current CAM rate and its historical rate changes over the past five years, the current sinking fund balance and any outstanding special levy decisions, and the delinquency rate among existing owners. These figures materially affect both cash flow and long-term asset quality.
