Korea Apartment Complex Data API - 아파트 단지정보 (MOLIT K-apt)

Korea Apartment Complex Data API: 아파트 단지정보 (MOLIT K-apt)

Get official facts about every South Korean apartment complex in a district as clean JSON / CSV / Excel: number of households and buildings, floors, use-approval (built) date, builder, unit size mix, heating, parking spaces, EV chargers, nearest subway station and nearby schools. Data comes from the Ministry of Land, Infrastructure and Transport (MOLIT) apartment management information system (K-apt, 공동주택관리정보시스템) through the official open data API, not from scraping listing sites.

Pairs with our Korea Real Estate Scraper (실거래가): join transaction prices to complex facts on the complex name and legal-dong code.

What you can use it for

• Proptech and valuation models: features like built year, households, floors, parking per household, heating and size mix for AVMs and price models.
• Investment screening: list all complexes over 1,000 households built after 2010 in a district, with the nearest subway.
• Market research: count complexes and households by builder (삼성물산 래미안, GS건설 자이, 현대 힐스테이트) or by district.
• Data enrichment: attach English building facts to Korean addresses or complex names you already have.
• Services and B2B: management-company names and complex counts for facility, EV charging or telecom sales planning.

FAQ

Which complexes are covered? Apartment and mixed-use residential complexes registered in K-apt, which covers complexes that must disclose management information by law (generally 150+ households or with elevators/central heating). Small villas and officetels are mostly not included.

Does it include prices? No. Use our Korea Real Estate Scraper for official sale and rent prices, then join on complex name and legal-dong code.

Does it include personal data? No. Only building facts and the management office phone published by MOLIT. No owner or resident information.

Can I search in English? Region names work in English or Korean. Complex names are Korean in the source; a romanized name is added to every row and the name filter also matches romanized text.

How fresh is the data? It is read live from the official API on every run.
