What to know before you go
Daejeon had Korea's worst per-capita jeonse fraud, and the reason is a building type
CriticalBy the government's own recognised-victim counts, Daejeon has run at the highest rate of jeonse-fraud victims per head of population of any region in the country, with the third-highest absolute total after Seoul and Gyeonggi despite being a city of 1.44 million. That is not a coincidence of bad luck: Daejeon has an unusually high share of 다가구주택 — multi-household houses, where one owner holds one registered title over a building full of separate tenancies. Every tenant ranks against the same property by the date of their fixed-date stamp, so being fifth through the door means four deposits sit ahead of yours before the mortgage is even counted. Prefer a registered apartment unit for a first lease, and if you do take a villa or multi-household house, get the building's 전입세대확인서 and 확정일자 부여현황 before any money moves.
The special act that helped fraud victims does not cover a lease you sign now
CriticalThe Special Act on Support for Victims of Jeonse Fraud was extended in 2025 to run until 31 May 2027 — but the extension only reaches tenants whose lease was first signed on or before 31 May 2025. A contract signed after that date falls outside it entirely, whatever the recognition period says. Practically, that means the safety net people read about in the 2023-24 coverage is closing behind you, and the private protections — the property register, the tax-arrears check, the fixed date, and HUG's deposit-return guarantee — are now doing all of the work. Price the guarantee rather than assuming a rescue exists.
Check the landlord's unpaid taxes — and you no longer need their permission
CriticalUnpaid national and local taxes rank ahead of your deposit at auction. Since April 2023 a tenant whose deposit exceeds ₩10 million may inspect the landlord's unpaid national taxes at any tax office in the country, without the landlord's consent, from the moment the contract is signed until the lease start date, on production of ID and a copy of the contract; unpaid local taxes are inspected the same way at any si/gun/gu office. Before signing you still need consent, so ask for it and treat a refusal as an answer. Given what happened in this city, treat it as a required step rather than an optional one.
Your immigration office covers Sejong and half of Chungcheong as well as Daejeon
ImportantThe Daejeon Immigration Office is a full office whose jurisdiction runs across Daejeon, Sejong, South Chungcheong and the Okcheon and Yeongdong counties of North Chungcheong, with separate branch offices at Cheonan for the Cheonan and Asan belt and at Seosan and Dangjin on the coast. That catchment is far larger than the city, and it includes some of Korea's densest industrial foreign-worker populations. Do not assume a provincial office is quiet: book on HiKorea the week you land, and confirm which office actually covers your registered address before booking anything.
Tram construction will reshape the city, slowly and disruptively
ImportantDaejeon has run on a single metro line since 2006. Line 2 is a 38.8 km hydrogen-powered tram loop with 45 stations through five districts, which broke ground in 2025 after nearly three decades of planning. The original end-2028 opening has already slipped in official statements toward the turn of the decade, so treat any date as provisional. What is not provisional is several years of surface construction on the arterial roads it follows. Before signing a lease, look up whether your street is on the alignment and what phase it is in — a tram stop outside the door in 2031 is worth much less than a clear road in 2027.
This is a company town where the company is the government's research system
ImportantDaedeok Innopolis dates from 1973 and holds KAIST alongside a couple of dozen government-funded research institutes, and Government Complex Daejeon houses the customs, patent, procurement, forestry, statistics and military manpower administrations. The practical effects are unusual: a very high concentration of doctorates, a professional culture that runs on institute affiliation rather than corporate brand, hiring cycles tied to national R&D budgets rather than to markets, and a lot of fixed-term research contracts. If you are coming into that world, the question that matters is which institute and on what contract — not which industry.
