The two things that cost people money
Rental disputes in Chiang Mai almost always come down to one of two issues: a deposit that didn’t come back, or an electricity bill three times higher than expected.
Both are entirely avoidable, and both are avoided at the same moment — before you sign. This guide sits under our renting hub and covers what to ask, what’s normal, and what to do when something goes wrong.
Deposits: what’s standard
| Rental type | Typical deposit | Paid alongside |
|---|---|---|
| 12-month lease | 2 months’ rent | 1 month advance |
| 6-month lease | 1–2 months’ rent | 1 month advance |
| Monthly | 0–1 month | 1 month advance |
So a 15,000 THB flat on a yearly lease needs 45,000 THB on day one. That’s the number to have ready, and it’s the reason a Thai bank account matters early.
The deposit exists to cover damage and unpaid bills, not normal wear. In practice, what’s “normal wear” is decided by whoever has evidence.
The move-in record
This is the single highest-value twenty minutes in the whole rental process.
On the day you get the keys, before you move anything in:
- Photograph every room, wall, floor and ceiling.
- Close-up every existing mark, scratch, stain, chip and burn.
- Photograph the meter readings for electricity and water.
- Test and film anything that doesn’t work — a socket, a tap, a window latch.
- Email or message the whole set to the landlord the same day, with a short note.
That message is your evidence. It costs nothing and it resolves virtually every deposit argument before it starts.
The electricity markup
Thailand’s Provincial Electricity Authority charges a regulated per-unit rate, currently in the region of 4–5 THB depending on consumption tier. Many condo landlords bill tenants at their own rate instead — 6, 7, sometimes 8 THB a unit.
It’s legal in the sense that it’s contractual, and it’s extremely common. What’s not acceptable is a landlord who refuses to tell you the rate before you sign.
Why it matters: a typical air-conditioned one-bedroom in hot season can consume 400–700 units a month. At the government rate that’s roughly 2,000–3,000 THB. At 8 THB a unit it’s 3,200–5,600 THB. Across March, April and May the difference is real money.
Ask for the per-unit rate in writing, before signing. A landlord who answers straight away is telling you something good about how they’ll handle everything else too. Our guide to renting a condo has the full list of pre-signing questions.
Other charges to check
- Water. Usually cheap and metered, sometimes a flat monthly charge.
- Common-area fee. Some buildings charge tenants a monthly maintenance fee; many roll it into rent.
- Internet. Rarely included. Budget 500–800 THB for fibre.
- Cleaning and aircon servicing. Confirm who pays. Aircon servicing twice a year is normal and someone has to fund it.
- Parking. Usually free for scooters, sometimes charged for cars.
Getting the deposit back
Three things decide this:
Notice. Give the exact period the contract states, in writing. Verbal notice to a landlord who later doesn’t remember it is worth nothing.
Condition. Clean the unit properly, including the aircon filters and the fridge. Fix anything you broke.
Handover. Do a joint walkthrough with the landlord present, take final meter photographs, and settle outstanding bills there and then.
If a deduction is proposed that you disagree with, ask for it in writing with a reason. Most landlords, faced with a documented move-in record and a calm request, drop it. If they don’t, the amounts involved rarely justify formal escalation — which is exactly why the photographs at the start are the real protection.
