Seoul to halve public contribution rate in 11 northern districts to spur private development

The Seoul Metropolitan Government plans to cut the public contribution rate in half for 11 districts where low land values have long delayed development, aiming to accelerate private investment, balanced regional growth and housing supply.

The city announced Thursday it would introduce a new system called the "win-win development pre-negotiation+" regime, which applies tailored incentives to areas with weak development conditions.

The targeted districts are those whose officially assessed land prices fall at or below 60 percent of the city average and face comparatively poor development conditions. They are Gangseo-gu, Gangbuk-gu, Guro-gu, Geumcheon-gu, Dobong-gu, Seodaemun-gu, Seongbuk-gu, Eunpyeong-gu, Jungnang-gu, Nowon-gu and Dongdaemun-gu.

Under the new system, the uniform negotiation standards previously applied across the city will be replaced with a tailored framework reflecting each district's characteristics. The city will lower the public contribution rate from 60 percent to 30 percent and allow the residential ratio to be set through negotiations that weigh location, development conditions and public interest.

The intent is to reduce the public contribution burden, apply the residential ratio more flexibly to improve project viability and thereby attract private investment.

The city said the new system builds on the pre-negotiation regime for urban planning changes it first introduced nationwide in 2009, with the latest guidelines revision serving as the basis for the new framework. It also said the system marks the first concrete step toward institutionalizing a key 9th-term campaign pledge — a "super-strong incentive" to improve housing conditions in northern Seoul.

The city said it had previously pursued efforts to narrow the development gap between districts through a balanced-development pre-negotiation scheme, but found that some areas could not secure sufficient project viability due to residential ratio requirements, limiting its ability to draw in private participation.

Beyond the regulatory changes, the city plans to identify candidate sites with development potential and push forward pilot projects. It will hold briefing sessions for landowners and developers in the target areas and support project development through site identification and preliminary consulting. The city also intends to use the pilot projects to verify the system's effectiveness and address any shortcomings.

"The win-win development pre-negotiation+ system is the concrete mechanism for delivering the super-strong incentive to improve northern Seoul housing — a core campaign pledge of the 9th elected term," said Kim Yong-hak, the city's director of future space planning. "We will invigorate private investment and accelerate balanced development across Seoul by offering reasonable incentives even in areas where development has stalled due to poor project viability."
