What shows up on your Korean apartment's monthly bill
Every apartment carries a building maintenance fee, an electricity bill, and a gas bill each month, plus water every couple of months, and how much each one actually costs depends more on your building and district than any single number can tell you.

Nobody hands you a bill glossary when you move in. You get a key, maybe a landlord who speaks no English, and a stack of paper in your mailbox that looks like it matters. It does.
Here's what's actually in it, and, as much as we could verify, where the money comes from.
| Bill | Korean term | Who sets it | Billing cycle |
|---|---|---|---|
| Building maintenance fee | 관리비 (gwalli-bi) | Each building's management office, no public rate table | Monthly |
| Electricity | 전기요금 (jeongi-yogeum) | KEPCO, tiered by usage | Monthly |
| Gas (heating + stove) | 도시가스 (dosi-gaseu) | Local city gas company, approved by the province | Monthly |
| Water | 수도요금 (sudo-yogeum) | Local water authority, metered by the ton | Usually every 2 months |
관리비: the one that never quite explains itself
This covers the elevator, hallway lighting, security, sometimes cleaning. It's set building by building, so there's no national rate card, but there is data for registered apartment complexes. Nationwide, the average monthly maintenance fee per square meter for apartments rose from about 2,091 won in 2015 to about 2,920 won in 2024, a roughly 40% increase. Last year, the average maintenance fee for an 84㎡ Seoul apartment ran around 280,000 won a month. That's a family-sized unit in a registered complex, not the studio or one-room most teachers get; those are usually smaller and often sit in villas or officetels that don't report to the same public system. Ask the landlord or building office for last month's actual bill. That's the only number worth trusting.
Electricity: tiered, and the tiers matter more than the rate
KEPCO doesn't charge a flat rate per kilowatt-hour. Electricity fees are built from a basic charge, a usage charge, a fuel-cost adjustment, and a climate-environment charge, and can be supplemented with tiered or progressive rates when needed. In plain terms: the more you use in a month, the steeper the price gets on the last chunk of it, and the exact breakpoints shift a little from year to year and season to season. Rather than quote you a number that'll be wrong by next winter, check KEPCO's own calculator (online.kepco.co.kr) once you have a bill in hand. Punch in your kWh and it'll show you exactly which tier you landed in.
Gas: the one that gets people
Korean apartments heat through the floor, ondol-style, so your gas bill in January runs far higher than in September. That part isn't a mystery. What's less obvious is that the rate itself isn't national. Seoul's residential city gas rate is among the cheapest in the country, while some other regions charge noticeably more per megajoule. Same appliance, same weather, different bill, because your local gas company sets its own rate and gets it approved by the city or province, not by a single national office.
Water: cheap by world standards, uneven by region
The national average price of tap water is about 829 won per ton, ranging from about 786 won in metro cities up to 1,017 won in smaller counties and 944 won on Jeju. The gap between the cheapest and most expensive counties runs about four times over. Most residential billing still comes every two months, though some cities are experimenting with digital meters that could eventually move toward monthly reads.
Who actually pays this
- Check your contract's wording on utilities so everyone is working from the same page.
- Some schools cover 관리비 and nothing else; some cover a monthly cap and bill you the rest.
- Confirm in your first week which bills are yours. Arrangements differ from school to school.
If the apartment's in your name, you register with KEPCO (call 123) and with the local city gas company, usually by phone. Once you've got a Korean bank account, set up 자동납부 (autopay) through the bank's app. Untangling a missed bill in a foreign name, over the phone, in Korean, is not how you want to spend a Saturday.
One thing we still don't have a clean answer for: officetel and villa maintenance fees, which is what most teachers actually live in, aren't in any public database the way registered apartment complexes are. Ask for last month's real bill before you assume anything.
