How Much Is a One-Room Apartment in Seoul? 2026 Guide

If you are planning to live in Seoul, one of the first questions you may have is: How much does a one-room apartment cost?

The short answer is that a typical one-room apartment in Seoul costs around ₩690,000 per month in rent, based on July 2026 actual transaction data for small studio units with a deposit of ₩10 million.

However, your actual cost can vary significantly depending on the neighborhood, apartment type, deposit, maintenance fee, and proximity to subway stations.

In this guide, we will look at Seoul one-room rent in 2026, the most expensive and affordable areas, deposit requirements, maintenance fees, and what foreigners should know before signing a lease.

Average One-Room Rent in Seoul

According to July 2026 data analyzed by real estate platform Dabang using actual transaction data from Korea's Ministry of Land, Infrastructure and Transport, the average monthly rent for one-room units in Seoul was ₩690,000.

The data covers studio units of 33㎡ or less in multi-family and multiplex housing, based on a ₩10 million security deposit.

Item	July 2026 average
Monthly rent	₩690,000
Security deposit	₩10 million
Average jeonse deposit	₩219.36 million
Unit size	33㎡ or less
Housing type	One-room / studio
Area	Seoul

One important point is that ₩690,000 is not the price of every studio in Seoul.

It is an average based on a specific type of housing and deposit amount. A newer studio near a major subway station can cost considerably more.

How Much Does a One-Room Cost by Neighborhood?

Location makes a big difference in Seoul.

The July 2026 data showed significant differences between districts.

Seoul district	Average monthly rent
Gangnam	₩970,000
Yongsan	₩870,000
Seongdong	₩820,000
Gwanak	₩810,000
Mapo	₩770,000
Seocho	₩750,000
Gwangjin	₩740,000
Jungnang	₩740,000
Dongdaemun	₩730,000
Seoul average	₩690,000

Gangnam was the most expensive district, with an average monthly rent of ₩970,000, about 41% higher than the Seoul average.

It has also remained the most expensive district for one-room rentals for 14 consecutive months in the latest data.

Is ₩500,000 Enough for a One-Room in Seoul?

Yes, but your options may be limited.

A monthly rent of around ₩500,000–₩600,000 can still be possible, especially if you are flexible about:

• Distance from the subway

• Building age

• Apartment size

• Floor level

• Furnishing

• Neighborhood

You may also find lower-priced rooms in areas farther from central Seoul.

However, it is important not to compare rent alone.

A ₩550,000 room with a ₩150,000 maintenance fee may actually cost more each month than a ₩650,000 room with a ₩50,000 maintenance fee.

---

What Is a Realistic Budget?

For someone looking for a basic one-room apartment in Seoul, these ranges can be useful as a starting point.

₩500,000–₩700,000

This is the lower-to-average range.

You may find:

• Older one-room studios

• Smaller units

• Buildings farther from central Seoul

• Rooms near universities

• Properties with fewer amenities

₩700,000–₩1 million

This is a more comfortable budget for many locations.

You will have more choices regarding:

• Subway access

• Building condition

• Room size

• Furnishing

• Neighborhood

₩1 million+

At this level, you can consider more expensive neighborhoods such as Gangnam, Yongsan and some areas of Seongdong.

Newer officetels or larger studios can also fall into this range.

---

What About Maintenance Fees?

Rent is not necessarily your total housing cost.

Many Korean studios charge a separate maintenance fee, often called 관리비.

This may cover some combination of:

• Building cleaning

• Common-area electricity

• Water

• Internet

• Security

• Elevator maintenance

• Building management

But what is included varies from property to property.

For example, Dabang's July 2026 analysis of studios near 10 major Seoul universities found average monthly rent of ₩625,000, while the average maintenance fee was ₩84,000.

That means the combined average was roughly ₩709,000 per month, before considering other personal utilities.

So when comparing apartments, always ask:

“Is the maintenance fee included in the rent?”

and

“What exactly does the maintenance fee cover?”

One-Room vs. Officetel

Foreigners searching for housing in Seoul will often see both one-room and officetel listings.

They are similar but not exactly the same.

According to the Seoul Metropolitan Government, an officetel is a residence-like building originally designed as a combination of office and residential space.

One-room studios are generally smaller versions of this type of housing and tend to have lower monthly rents than officetels.

One-room

Usually:

• Smaller

• More affordable

• Common near universities

• Often found in multi-family buildings

• Good for students and people on a budget

Officetel

Usually:

• Newer buildings are easier to find

• Convenient locations

• Often furnished

• Better building facilities

• Usually more expensive

If you want convenience and modern facilities, an officetel may be attractive.

If your priority is keeping rent low, a traditional one-room may offer better value.

What Is the Security Deposit in Seoul?

One of the biggest differences between renting in Seoul and renting in many other countries is the security deposit.

For monthly rent, known as wolse (월세), you generally pay:

Security deposit + monthly rent

For example:

Deposit: ₩10 million
Monthly rent: ₩690,000

The July 2026 Seoul studio average of ₩690,000 is specifically based on a ₩10 million deposit.

However, different combinations are possible.

For example:

₩5 million deposit + higher monthly rent

or

₩20 million deposit + lower monthly rent

The exact relationship depends on the property and landlord.

---

What Is Jeonse?

You may also encounter jeonse, one of Korea's unique rental systems.

Instead of paying monthly rent, the tenant provides a large lump-sum deposit for the lease period.

The Seoul Metropolitan Government explains that jeonse generally involves leasing a home for one to two years with a large deposit, which should be returned when the contract ends, subject to applicable conditions.

For Seoul one-room units of 33㎡ or less, the July 2026 average jeonse deposit was approximately ₩219.36 million.

That is why jeonse is usually much less accessible for students or newcomers without significant savings.

For many foreigners, wolse with a manageable deposit is easier to understand and budget for.

How Much Money Do You Need to Move Into a Seoul One-Room?

Do not prepare only the first month's rent.

Your initial housing budget may include:

1. Security deposit

2. First month's rent

3. Real estate agency fee

4. Maintenance fee

5. Utility bills

6. Furniture or household items

7. Moving expenses

For example, if you rent a studio for:

₩700,000 monthly rent + ₩10 million deposit

you may need considerably more than ₩700,000 before you can move in.

The Seoul Metropolitan Government also notes that brokerage fees vary depending on the type, size and price of the property.

Which Areas Are Better for Foreigners?

There is no single best neighborhood because it depends on your lifestyle.

If you work in Gangnam, paying more to live nearby may save you significant commuting time.

If you are a student, university areas may offer more affordable studios.

If you want central Seoul and convenient transportation, areas such as Mapo, Yongsan or Seongdong may be worth considering, although rents can be above the Seoul average.

The most important thing is to compare:

Rent + deposit + maintenance fee + transportation cost

rather than looking at rent alone.

---

Where Should Foreigners Look for a One-Room?

Foreigners should be particularly careful when signing a Korean rental contract.

The Seoul Metropolitan Government recommends using licensed real estate agencies and provides information about real estate agencies that can assist foreigners in languages such as English, Chinese and Japanese.

Before signing a contract, check:

• Exact deposit

• Monthly rent

• Maintenance fee

• Utilities included

• Contract period

• Early termination conditions

• Deposit return conditions

• Furniture and appliances

• Building management fees

Do not send a large deposit simply because someone sends you photos of an apartment online.

Whenever possible, verify the property and contract through a legitimate real estate professional.

Is Seoul One-Room Rent Getting More Expensive?

The latest data suggests that rental pressure remains significant.

The average Seoul one-room monthly rent increased from ₩640,000 in June 2026 to ₩690,000 in July, a monthly increase of about 6.7%. At the same time, the average jeonse deposit decreased slightly.

This shows why using an older blog post to estimate Seoul rent can be misleading.

Housing prices change by month, neighborhood and property type.

If you are moving to Seoul, it is better to check recent actual transaction data and current listings rather than relying on a single historical average.

Final Thoughts

So, how much is a one-room apartment in Seoul?

For a typical small studio, a reasonable starting point is around ₩690,000 per month, based on the latest July 2026 actual transaction data and a ₩10 million deposit.

But your realistic budget should be higher once you include maintenance fees, utilities and other housing expenses.

A simple guide is:

₩500K–₩700K: Budget-friendly options
₩700K–₩1M: More choices and better locations
₩1M+: Premium neighborhoods or newer properties
