Splitting a condo with someone in Bangkok sounds like a great plan until you realize the landlord only listed one name on the lease, your roommate adopted a cat without asking, and now nobody knows who owes what for the electric bill. Living with a roommate here can save you serious money, but it comes with its own set of complications that most rental guides never bother to mention.

Bangkok is one of the best cities in the world for affordable condo living, and sharing a place makes it even more accessible. A two bedroom unit near BTS On Nut that runs 18,000 to 25,000 THB per month suddenly becomes very manageable when you split it down the middle. But before you start browsing listings with your best friend or that coworker who seems chill enough, let's talk about what you actually need to know.

What Bangkok Landlords Actually Think About Roommates

Here is the reality most people discover too late: many condo landlords in Bangkok are not thrilled about two tenants sharing a unit, especially if only one person signed the lease. Some buildings, particularly higher end ones like those in the Thonglor or Phrom Phong area, have juristic office rules that limit the number of registered residents per unit.

At a building like The Base Park West near BTS On Nut, for example, each resident typically needs a registered key card. If your landlord only arranged one card and the juristic person sees an unregistered tenant coming and going every day, it can create problems. You might get flagged, fined, or even asked to leave.

The fix is simple but important. Be upfront with your landlord from day one. Tell them you plan to share the unit. Most landlords will agree, especially if it means reliable rent payments. Some may charge a slightly higher security deposit, usually an extra 5,000 to 10,000 THB, which is fair enough. Transparency saves everyone a headache later.

Getting Both Names on the Lease

This is the single most important thing you can do. If both roommates are on the lease, both have legal standing. If only one name is listed, the other person is essentially a guest with zero rights if something goes wrong.

Let's say you and a colleague rent a two bedroom condo near MRT Phra Ram 9 for 22,000 THB per month. You split everything 50/50, but only your colleague's name is on the contract. Three months in, they decide to move out. Guess who has no legal claim to stay? You. The landlord can ask you to leave immediately because, on paper, you were never a tenant.

Ask the landlord to include both names on the rental agreement. If they refuse, at minimum draft a simple written agreement between you and your roommate that outlines each person's share of rent, deposit, utilities, and what happens if one person wants to leave early. It does not need to be fancy. A signed document with both your names, the date, and the key terms will hold up far better than a verbal promise.

Splitting Costs Without Splitting Friendships

Money ruins roommate relationships faster than anything else in Bangkok. Electricity here is billed per unit, and many landlords charge 7 to 9 THB per unit instead of the 3 to 4 THB government rate. Water is usually a flat fee or charged per unit as well. Internet runs around 600 to 900 THB per month for decent fiber.

A couple sharing a one bedroom at Lumpini Park Rama 9, paying 14,000 THB rent plus roughly 2,500 THB in electricity during hot season plus 700 THB internet, is looking at about 17,200 THB total. Split that and you are each paying 8,600 THB to live near an MRT station. That is genuinely hard to beat.

Set up a shared expense tracker from the start. Apps like Splitwise work well, or even a shared Google Sheet. Decide early whether you split everything equally or proportionally based on room size. And pay each other on the same day every month. Consistency prevents resentment.

Know Your Rights If Things Go Sideways

Thai rental law tends to favor landlords, but tenants do have protections. If both names are on the lease, the landlord cannot evict one person and keep the other. They also cannot raise rent mid contract or withhold your deposit without documented reasons.

Imagine you are renting a place on Soi Sukhumvit 50 near BTS On Nut with a roommate. The landlord decides they want to sell the unit and gives you 30 days notice, but your lease runs for another eight months. They cannot force you out. The lease is a binding contract. You have the right to stay until it expires, regardless of a sale.

Document the condition of the condo when you move in. Take photos and videos of every room, every mark on the wall, every scratch on the floor. Send them to the landlord via Line or email so there is a timestamp. When move out day comes, this protects both you and your roommate from unfair deposit deductions.

Choosing the Right Condo for Sharing

Not every Bangkok condo works well for roommates. A 30 square meter studio with one bathroom will test any friendship. Look for units with at least 45 square meters, two bedrooms, and ideally two bathrooms. Buildings along the BTS Sukhumvit line from Bearing to Ekkamai tend to offer the best value for larger layouts.

Check that the building allows two key cards and two parking cards if needed. Visit the unit together before signing. Make sure both bedrooms are livable, not just one real room and a converted storage closet that the listing generously calls a second bedroom. This happens more often than you would think, especially in older buildings around Victory Monument or Ari.

Sharing a condo in Bangkok is one of the smartest financial moves you can make, but only if you set it up properly. Get both names on that lease, agree on money matters before you move in, and pick a unit that actually fits two people.
