Korea Insight Now: Why Do So Many Koreans Live in Apartments? Land, Jeonse and Apartment Life Explained

More than half of all households in South Korea live in an apartment. In the latest official count, 54.5% of ordinary households lived in one, and apartments made up 65.8% of all homes in the country. That is about two of every three homes.

So why? There is no single reason. Mountains leave little flat land. Cities grew very fast, and the government answered by building whole apartment towns at once. Over time apartments also became the easiest home to price, sell and rent out, so they turned into the main way Korean families hold their wealth.

This guide goes through the numbers first, then each reason, then the parts of apartment life that surprise visitors: brand names on the buildings, strict rules about noise between floors, shoes at the door, and a monthly fee for everything in between.

At a Glance

Apartments are 65.8% of all homes in Korea, and 54.5% of households live in one (Statistics Korea, as of November 1, 2025).
About 70% of the peninsula is mountains or hills, so cities build up instead of out.
In the late 1980s and early 1990s the government built new apartment towns such as Bundang and Ilsan to ease a serious housing shortage.
Apartments are the easiest homes to price and resell, and they fit jeonse, Korea's lump-sum rental deposit.
Foreign buyers in Seoul and much of the capital area now need a permit and must live in the home for two years.

The Numbers: How Many Koreans Live in Apartments?

The figures come from the Population and Housing Census (인구주택총조사, Ingu Jutaek Chongjosa). Since 2015, Statistics Korea has run it every year by linking government records such as resident registrations and building registers. The latest results, released on July 28, 2026, describe the country as of November 1, 2025. (Statistics Korea now operates under the name 국가데이터처, the National Data Office.)

Here are the main results:

Homes: Korea had 20.18 million homes. 13.29 million of them were apartments, or 65.8%.
Households: 54.5% of ordinary households (about 12.26 million) lived in an apartment. Another 27.2% lived in detached houses and 10.8% in low-rise "villa" buildings.
Not counted as housing: 6.1% of households lived in places the census does not count as housing, such as officetels (studio units in office-type buildings, explained below).

Why are the two numbers different? The first counts buildings. The second counts people's households, and some households live in places that do not count as housing at all. Both numbers point the same way.

The trend only goes one way. Apartments were already 47.8% of homes in 2000, the year they overtook detached houses as the most common type. The share of households living in apartments rose from 48.1% in 2015 to 54.5% in 2025. Of the roughly 280,000 homes completed in the first ten months of 2025, about 250,000 were apartments.

It also depends a lot on where you are:

Sejong (세종), the newer administrative capital: 87.6% of homes are apartments, the highest in the country.
Gwangju (광주): 82.0%. Daejeon (대전): 77.0%.
Seoul (서울): 60.7%. Seoul also has many low-rise multi-household buildings, 26.2% of its homes.
Jeju (제주): only 31.7%. It is the only region where detached houses outnumber apartments.

Apartment, Villa, Officetel, or House?

Korean housing words do not match English ones exactly. A Korean "villa" (빌라) is not a luxury holiday home. It means a small, low-rise apartment-style building. Here is how the four main types compare.

	Apartment (아파트)	Villa (빌라: 연립·다세대)	Officetel (오피스텔)	Detached / multi-family house (단독·다가구)
Legal definition	Shared housing with 5 or more residential floors	Shared housing with 4 or fewer residential floors (row houses and multi-household buildings)	Classified as a business facility under the Building Act, not as housing	A single house, or a multi-family house of up to 3 residential floors sold as one property
Share of households, 2025	54.5%	10.8%	Part of the 6.1% living outside "housing"	27.2%
Typical setting	Large complexes with many towers	Single buildings on ordinary streets	Near offices and subway stations	Older neighborhoods, small towns, rural areas
Shared facilities	Management office, security, playgrounds, parking, often a gym or library	Few or none	Usually a front desk or manager, parking varies	None
Who often lives there	Families, but every age group	Young people, smaller households	Single workers, students	Older owners, tenants renting rooms or floors
Short-term stay for foreign tourists	Possible only if registered as a foreigner homestay (see FAQ)	Same rules as apartments	Cannot be registered as a homestay	Possible if registered

Reason 1: Mountains Leave Little Flat Land

The Korean Peninsula is mostly mountains. Yonhap News' official Korea in Brief guide puts it plainly: only about 30% of the land is flat, and there are no vast plains.

The flat land that does exist is already taken by farms, rivers, roads and older city centers. Seoul is a good example. The city sits in a river basin ringed by mountains, so there is only so much room to spread out.

When land is limited and demand keeps rising, you build up. A high-rise complex can house thousands of households on land that might hold a few dozen detached houses.

Reason 2: Cities Grew Fast, So the State Built Whole Towns

From the 1960s on, millions of people moved from farming areas to Seoul and other cities for factory and office jobs. Housing did not keep up.

The numbers show how bad it got. By the end of 1987, the housing supply ratio in Seoul was only 56.2%, according to the National Archives of Korea. The housing supply ratio compares the number of homes to the number of households, so Seoul had roughly 56 homes for every 100 households. Prices were climbing fast.

The government's answer was the 2 Million Homes Plan (주택 200만호 건설계획). Its goal was to build 2 million homes from 1988 to 1992, with special attention to low-income and homeless households, according to a 1991 Ministry of Construction review now held by the Presidential Archives.

The biggest part of the plan was five new towns on the edge of Seoul, announced in April 1989:

Bundang (분당): the largest, planned for about 97,500 homes and 390,000 people
Ilsan (일산): about 69,000 homes
Pyeongchon (평촌), Sanbon (산본) and Jungdong (중동): about 42,000 homes each

Together they added about 293,000 homes, which the National Archives compares to 22% of Seoul's housing stock at the time. Koreans now call them the "first-generation new towns" (1기 신도시). The archives record says the 2 million target was reached in September 1992, before the new towns were even finished.

Why apartments, not houses? Speed and scale. Building tall towers on large, cleared plots was the quickest way to add hundreds of thousands of homes. That model of a big complex, standard floor plans and a school in the middle became the template for later new towns too.

Reason 3: Apartments Are the Easiest Home to Price and Sell

For many Korean families, an apartment is more than a place to live. It is their savings account.

Look at where household wealth sits. In the 2025 Survey of Household Finances and Living Conditions, the average household held 566.78 million won in assets. Of that, 76% was real assets, mostly real estate. Only 24% was financial assets such as savings and stocks.

Apartments became the favorite form of that wealth because they are easy to compare. Units in the same complex share the same layout and size, so a buyer can see what similar units sold for. Real estate sales in Korea must be reported to the government within 30 days of the contract, and the Ministry of Land (MOLIT) publishes actual sale prices online.

That makes an apartment liquid. Liquid means you can sell it quickly at a fair price. A detached house or an older villa is harder to value, so it can take longer to sell and is harder to borrow against.

There is a flip side. When so much family wealth sits in one kind of asset, apartment prices become a national obsession and a political issue. That is why the government keeps adjusting lending rules and transaction permits, including the rules for foreign buyers in the FAQ below.

Reason 4: Jeonse, Korea's Lump-Sum Lease

Jeonse (전세) is a rental system that barely exists outside Korea, and it is closely tied to apartments.

Here is how it works. Instead of paying monthly rent, the tenant hands the landlord a large lump-sum deposit at the start, often a big share of the home's price. The tenant then lives there without monthly rent. When the lease ends, the landlord returns the full deposit.

So how does the landlord make money? By using the deposit in the meantime, for example by putting it in savings or toward buying another home. For the tenant, jeonse is a way to live somewhere better while saving toward a purchase.

The law gives tenants some protection. Under Korea's Housing Lease Protection Act, a lease is treated as at least two years, and a tenant can ask to renew once for another two years.

Apartments fit jeonse well because their value is easy to check, so both sides can judge whether the deposit is safe. Many landlords also bought apartments with the help of tenants' deposits, which pushed demand for apartments even higher.

Jeonse has real risks, though. If the landlord cannot return the deposit, the tenant can lose a large amount of money. That is why deposit-return guarantees exist. The Seoul Housing Portal explains the guarantee from Korea Housing & Urban Guarantee Corporation (HUG), and says foreign tenants can apply too.

Reason 5: A Complex Works Like a Small Town

A Korean apartment complex (단지, danji) is not just a building. Large complexes often include:

A management office (관리사무소, gwalli samuso) that handles repairs, notices, parking and complaints
Security staff and controlled entrances
Playgrounds and green space between the towers, often with cars kept underground
Shared facilities such as a small gym, a study room or a senior center, depending on the complex
Schools nearby. School districts matter a lot to Korean parents, and new complexes are often planned around schools

Then there is the floor. Koreans have heated the floor rather than the air for a very long time. This tradition, ondol (온돌), was designated a National Intangible Heritage of Korea in 2018. Modern apartments carry it on with hot-water pipes under the floor, which is one reason people sit, play and even sleep close to the floor at home.

For parents with young kids, the appeal is simple. Children can walk to school and play outside without crossing a busy road, and help is a call to the management office away.

What Surprises Foreigners About Korean Apartments

Brand names on the towers. Big construction companies give their apartments brand names, often English- or French-sounding words, and paint them in huge letters on the side of each building. The brand works like a quality label, and residents care about it. Each building also has a large number (101, 102...) so delivery drivers and visitors can find the right tower.

Noise between floors (층간소음, cheunggan soeum). This is the most common neighbor problem. Korea even has a legal standard. For "direct impact noise" like footsteps or jumping, the limit is 39 dB averaged over one minute in the daytime (06:00–22:00) and 34 dB at night (22:00–06:00). Many residents put soft mats on the floor, wear indoor slippers and avoid running, laundry or moving furniture late at night. If a dispute gets serious, the Korea Environment Corporation runs a public mediation service called the Floor Noise Neighbor Center (층간소음 이웃사이센터), reachable at 1661-2642.

Shoes off at the door. Every apartment has a small entry area (현관, hyeongwan) a step lower than the floor. Shoes stay there. With floor heating and life lived close to the floor, outdoor shoes inside feel unclean.

The recycling area. Complexes have a collection point where residents sort paper, plastic, glass, cans and vinyl. General trash goes in official pay-per-bag garbage bags, a system used nationwide since January 1, 1995. Food waste is collected separately.

The management fee (관리비, gwallibi). Every month, residents pay a fee on top of rent or the mortgage. It covers things like cleaning, security, elevators, shared electricity and repairs, and it is often billed together with each unit's heating and utility use. Many complexes post their fees on K-apt, the government's apartment management information system, so you can compare before you move in.

Tips If You Live in or Visit a Korean Apartment

Take your shoes off at the entrance, even for a short visit.
Walk softly, and keep loud activities to daytime hours.
Ask the management office or a neighbor how recycling works in that complex. Sorting rules and pickup days vary.
Use the official pay-per-bag garbage bags sold for your city or district, available at convenience stores and supermarkets.
If you rent, ask what the monthly management fee usually is, and whether heating is included or billed separately.
Read notices in the elevator and lobby. That is where water shutoffs, inspections and noise reminders appear. A translation app helps.
Park only where the complex allows. Many complexes register residents' cars.

Cautions

Jeonse deposits are large. Before signing, check the property's registry (등기부등본, deunggibu deungbon, the official record of who owns it and what loans sit on it). If you want HUG's deposit-return guarantee, register your move-in and get a fixed-date stamp on the lease, and apply before half the lease period has passed.
Short-term rentals must be registered. An unregistered apartment listing is illegal lodging, and you may have little protection if something goes wrong. Officetels cannot be registered as homestays at all.
Buying rules change often. Permit zones and residency duties for foreign buyers are set for one year at a time. Check the latest rules before any contract.
Apartment numbers are not one story. 65.8% is the national figure. Some neighborhoods, especially in Seoul and Jeju, look very different.

FAQ

Q. What is jeonse?
A rental system where you pay one large deposit at the start instead of monthly rent, then get the full deposit back when you move out. The landlord uses the money in the meantime. A lease is treated as at least two years, with one tenant-requested renewal for two more. The big risk is a landlord who cannot repay, so check the property's existing debt and consider a deposit-return guarantee.

Q. Can foreigners buy an apartment in Korea?
Yes, but the Seoul area now has strict conditions. Since August 26, 2025, foreign individuals, companies and governments need a permit from the local city or district office before signing a contract to buy a home in all of Seoul, 23 cities and counties in Gyeonggi Province and most of Incheon. MOLIT extended the same zone for another year, from August 26, 2026 to August 25, 2027. After Incheon reorganized its districts in July 2026, the zone is listed as 9 Incheon districts (7 under the old map). A buyer who gets a permit must move in within four months and live there for two years. Breaking that rule can bring repeated fines of up to 10% of the purchase price and possibly a cancelled permit. Since February 10, 2026, foreign buyers also have to report their visa status and address. In permit zones they also submit a funding plan that covers overseas money. Separately, every apartment purchase in Seoul, by Koreans or foreigners, needs a permit through December 31, 2026. Outside these zones, foreigners can generally buy, but they still have to report the purchase. Rules are reviewed often, so confirm with the local office before you commit.

Q. Can travelers legally stay in an apartment rental?
Yes, if the place is registered. The common category is the Foreigner Tourist Urban Homestay (외국인관광 도시민박업). Under the Tourism Promotion Act, a resident can host foreign tourists in the home they actually live in, including an apartment, if it is in a city area and under 230 square meters. These homestays are meant for foreign tourists only. For apartments, the host must also follow the complex's management rules, which can require consent from the management or neighbors. Officetels cannot be registered at all. The government's local licensing site (localdata.go.kr) lets you check whether a business is registered. Airbnb also requires Korean listings to submit a business registration. Since October 16, 2025, unregistered listings cannot be booked for stays from January 1, 2026 onward.

Q. Why are apartments in K-dramas everywhere?
Because that is how most viewers live. With over half of households in apartments, a family drama set in an apartment looks normal to a Korean audience. Apartments also tell the story quickly. The complex, the brand and the floor hint at a character's money and status, and noise between floors and the management office give writers easy conflicts. That is also why the alley-house neighborhood in Reply 1988, set in Seoul's Ssangmun-dong (쌍문동), feels so nostalgic. It shows the kind of neighborhood many Koreans grew up in before the apartment era took over.
