공공지원민간임대 연계형 정비사업의 활성화를 위한 용적률 인센티브에 관한 연구

Abstract

The redevelopment linked to the public support private rental housing, which has changed since New Stay in the past, is not actively progressing. This is because publicity has been strengthened compared to the past, but sufficient incentives are not provided. Therefore, this study attempted to analyze the level of incentives required to revitalize the business in terms of increasing the floor area ratio. To this end, analysis parameters such as construction cost to real sale price ratio, rental housing sale price to real sale price ratio, rental housing supply ratio were set by referring to the cases of the ongoing redevelopment linked to the public support private rental housing. The minimum required incentive level and the change trend were analyzed by increasing the floor area ratio to keep the same profitability or alloted charges of shareholders between general redevelopment and the case of linking the public support system. The change in the floor area ratio incentive level was more sensitive to the rental housing sale price to real sale price ratio compared to the rental housing supply ratio. Especially it was found that under the current system, the project is difficult to proceed outside of the Seoul.
