ค่าส่วนกลางคอนโด: ใครต้องจ่าย เจ้าของหรือผู้เช่า

You just signed a lease for a nice one-bedroom condo near BTS Thong Lo. Rent is 22,000 THB per month, which felt like a solid deal. Then your landlord mentions something called "common area fees" and suddenly the math gets a little murky. Who actually pays for this? Is it baked into your rent, or is it an extra charge you need to budget for? If you have been renting in Bangkok for any length of time, you have probably bumped into this question. And the answer is not always as straightforward as you would hope. Let me break the whole thing down so you never get caught off guard again.

What Exactly Are Common Area Fees?

Common area fees, often called CAM fees (Common Area Maintenance), are the charges that cover the upkeep of shared spaces in a condo building. Think lobbies, swimming pools, gyms, gardens, security guards, elevator maintenance, hallway lighting, pest control, and garbage collection. Basically, everything outside your unit door that keeps the building running smoothly.

These fees are calculated per square meter of your unit. A typical rate in Bangkok ranges from 40 to 80 THB per square meter per month, depending on the building's age, location, and level of facilities. High-end developments like The Esse at Singha Complex near BTS Nana or 98 Wireless on Wireless Road can charge well above 100 THB per square meter because of their premium amenities and services.

According to DDproperty, the average common area fee for condos in central Bangkok sits around 50 to 70 THB per square meter per month. For a 35 square meter one-bedroom unit, that translates to roughly 1,750 to 2,450 THB per month. Not a massive number on its own, but over a year, it adds up to 21,000 to 29,400 THB. That is real money, and somebody has to pay it.

Who Is Legally Responsible for Common Area Fees?

Here is the part that matters most. Under Thai condominium law, specifically the Condominium Act B.E. 2522 administered by the Land Department, common area fees are the legal responsibility of the unit owner. Full stop. The juristic person office of the building collects these fees from registered co-owners, not from tenants.

This means that if you are renting a condo at Life Ladprao near BTS Ha Yaek Lat Phrao and your landlord has not been paying common area fees, the building management will go after the owner, not you. They can restrict access to certain facilities, impose late fees, and even take legal action against the owner. As a tenant, you are not on the hook in the eyes of Thai law.

That said, this is where the real world gets interesting. Just because the law says the owner pays does not mean your rental agreement says the same thing. Many landlords in Bangkok try to pass common area fees along to tenants, either by adding them on top of rent or by writing them directly into the lease. And if you sign a contract that says you will cover common area fees, then you have agreed to it voluntarily, and that agreement is enforceable between you and your landlord.

How It Works in Practice Across Different Price Ranges

Let me paint a few real scenarios from the Bangkok rental market so you can see how this plays out at different price points.

Take a studio unit at Lumpini Park Rama 9 near MRT Rama 9. Rent might be around 10,000 to 13,000 THB per month. At this budget level, landlords frequently try to pass the common area fee to tenants because their margins are already thin. The fee might be 1,200 to 1,500 THB per month. If you are not careful, you could end up paying almost 15% more than the listed rent.

Now consider a two-bedroom at Ashton Asoke near BTS Asok, where rent runs 45,000 to 65,000 THB per month. At this level, most landlords absorb common area fees into the rent because the numbers are large enough to accommodate them. The competition at this price bracket is also fierce, so landlords who try to tack on extra charges tend to lose tenants to buildings with simpler pricing.

Then there is the ultra-luxury segment. A unit at The Residences at Mandarin Oriental on Charoen Krung might rent for 200,000 THB per month or more. Common area fees here can exceed 150 THB per square meter, pushing monthly CAM charges for a large unit to 15,000 to 25,000 THB. Even at these prices, the owner typically covers the common area fee, but every detail is negotiated case by case.

Price Segment	Typical Rent Range (Monthly)	Common Area Fee (Monthly Est.)	Who Usually Pays CAM?	Example Building
Budget (Studio/1-Bed)	8,000 to 15,000 THB	1,000 to 1,800 THB	Often passed to tenant	Lumpini Park Rama 9 (MRT Rama 9)
Mid-Range (1-Bed/2-Bed)	18,000 to 35,000 THB	1,500 to 3,000 THB	Usually included in rent	Life Ladprao (BTS Ha Yaek Lat Phrao)
Upper Mid (1-Bed/2-Bed)	35,000 to 65,000 THB	2,500 to 5,000 THB	Almost always owner pays	Ashton Asoke (BTS Asok)
Luxury (2-Bed/3-Bed)	65,000 to 150,000 THB	4,000 to 12,000 THB	Owner pays	The Esse Singha Complex (BTS Nana)
Ultra-Luxury	150,000 THB and above	10,000 to 25,000+ THB	Owner pays (negotiable)	Mandarin Oriental Residences (Charoen Krung)

What to Check Before You Sign a Lease

The single most important thing you can do is read your lease carefully before signing. Look specifically for any clause mentioning common area fees, maintenance fees, CAM fees, or building management charges. If the lease says you pay them, you need to factor that into your total monthly cost and decide if the deal still makes sense.

Here is a real example I have seen play out more than once. A tenant found a great deal on a one-bedroom condo near BTS Ekkamai listed at 18,000 THB per month. The listing did not mention common area fees at all. When the lease arrived, there was a clause buried on page three stating the tenant was responsible for the common area fee of 2,100 THB per month, plus a sinking fund contribution if any special assessments were levied. That bumped the effective rent to over 20,000 THB, which changed the equation entirely.

Ask your landlord directly: is the common area fee included in the rent? Get it in writing. If the landlord insists you pay it separately, you can absolutely negotiate. Offer a slightly higher rent that includes the fee so you have one clean number each month. Most reasonable landlords will agree to this because it simplifies accounting for everyone.

Also check whether the building has any outstanding special assessments planned. The juristic person office sometimes levies one-time charges for major repairs like repainting the building exterior, replacing the pool system, or upgrading elevators. Under Thai law, these are the owner's obligation, but some landlords try to slip them into the tenant's responsibilities too. Research from Knight Frank Thailand shows that special assessments in aging Bangkok condos can run 500 to 2,000 THB per square meter, which for a 45 square meter unit could mean a one-time bill of 22,500 to 90,000 THB. You absolutely do not want to get stuck with that.

Common Area Fees vs. Utilities: Do Not Confuse Them

One mistake tenants make, especially those new to Bangkok, is confusing common area fees with utility charges. These are completely separate expenses. Utilities include electricity, water, and internet that you use inside your unit. Common area fees cover the shared building infrastructure outside your unit.

Say you rent a one-bedroom at Ideo Mobi Sukhumvit near BTS On Nut for 16,000 THB per month. Your utilities might run 2,000 to 4,000 THB per month depending on how much air conditioning you use. If the landlord also passes along the common area fee of 1,400 THB per month, your total monthly housing cost jumps from 16,000 to potentially 21,400 THB. That is a 34% increase over the headline rent. Always calculate your all-in cost before committing.

Electricity in Bangkok condos is charged either at the government rate of about 4 to 5 THB per unit or at the building's marked-up rate of 7 to 9 THB per unit. Water is usually 18 to 25 THB per unit at the building rate. These are tenant expenses everywhere in the city, no debate. Common area fees, though, remain that gray zone where the landlord and tenant need to reach an explicit agreement.

What Happens If Common Area Fees Are Not Paid?

If the owner falls behind on common area fees, the building's juristic person can take several actions. They might restrict the owner's voting rights at annual general meetings. They can charge penalty interest, which most buildings set at 10% to 15% per year. In extreme cases, the juristic person can file a civil lawsuit or even place a lien on the unit.

As a tenant, you might feel the effects indirectly. If your landlord is not paying common area fees, the building might restrict your access to amenities like the pool, gym, or parking. I have seen this happen at older buildings along Soi Sukhumvit 77 near BTS On Nut, where a few delinquent owners caused the building to cut off key card access for their tenants. It is awkward and uncomfortable, and it is entirely caused by the owner's negligence, not yours.

If you find yourself in this situation, document everything and communicate with both your landlord and the juristic person office. You may have grounds to terminate your lease early if the landlord's failure to pay common area fees materially affects your ability to use the property as intended.

At the end of the day, common area fees are one of those details that can quietly make or break a good rental deal in Bangkok. The law is clear that owners bear this responsibility, but the reality on the ground depends entirely on what your lease says. Know the numbers, ask the right questions, and always calculate your total monthly cost before you commit. A little homework upfront saves you from surprises later, and that peace of mind is worth its weight in gold when you are settling into a new home in this city.
