Korea's land ministry plans to cut developers' rezoning payments to turn office sites into housing

The plan cuts in two directions at once. The ministry wants developers to pay less when land is rezoned ^[1]. It also wants a legal basis for charging them on zoning upgrades and changes in permitted use inside a single use zone, where no such basis has existed ^[2]. Under the National Land Planning and Utilization Act, contributions can be levied only when land moves between zone categories, such as residential to commercial, so local governments have set their own rates for everything else ^[6]. A ministry official said the aim is "to help make it easier to convert commercial and office land into residential land" ^[7].

A contribution is the part of a rezoning gain that a developer hands back as public facilities, land or cash when a plan change raises the floor area ratio ^[5]. Seoul has already made the large cut. If its July rate is a share of the gain, a developer in the 11 districts now keeps 70% instead of 40%, or 1.75 times as much ^[12][18]. The same month the city cleared a knowledge industry center site on the former CJ factory grounds in Gayang-dong for about 960 apartments ^[13].

The supply count explains the hurry. Seoul finished 6,065 fewer homes in the first eight months than a year earlier ^[19]. The starts figure is thinner than its 41% headline. Take out July and the other seven months produced 14,293 starts, close to the roughly 14,700 that the 41% gain implies for all eight months of last year ^[20][21]. Land Minister Hong Ji-sun told a National Assembly audit on the 7th that "housing starts have fallen markedly over the past three years, and it is also true that move-ins are being delayed" ^[11].

The government is choosing conversion over new land. Officials say new development in city centers is difficult and redevelopment takes years ^[16]. The ministry counts about 1 million square meters of unbuilt city-center land in Seoul and 750,000 square meters across 15 regulated areas of Gyeonggi Province, 1.75 million in all ^[8][17]. It says those sites could take housing immediately through use-zone changes, yet they have sat undeveloped for long periods ^[8].

The study could set a national rate below what local governments now charge, raising returns and restarting stalled projects as officials intend ^[15]. It could instead put a national charge on within-zone upgrades that leaves some projects paying more than local practice asks ^[2]. Or the research could run long enough that the sites stay idle while it does. The request for proposals asks for recapture levels "that allow projects to proceed while blocking claims of preferential treatment" ^[4].

I think the bigger cut for Seoul developers came from the city in July, and the national study is mostly about standardising rates, or rather about giving the ministry a statute to charge where it now has none. Seongnam has also trimmed burdens without waiting, lowering the mandatory rental share in redevelopment to 10% from 12% ^[14]. The ministry has not published a target rate or a timeline, and its material does not mention REITs; the only sites it sizes are unbuilt land ^[8]. This view is wrong if the national rate lands below Seoul's 30% ^[12], or if Seoul starts outside one-off months begin to climb.
