With the implementation of the central government’s Integrated Public Rental Housing (IPRH) policy, the rent system for public rental housing has shifted from a cost-based system to an income-based one that considers both rental market prices and household income. However, when IPRH is provided in areas with high rental prices, the rent burden for residents increases compared to existing Public Rental Housing types. Therefore, it is necessary to adjust the rent system for IPRH so that the specificity of Seoul with high rental prices can be taken into account, and this study aimed to develop a rent adjustment factor to realize the reduction of rent levels. First, we set the upper limit of the rent-to-income ratio for moving-in households at 25% as the basic direction for calculating the adjustment factor. The adjustment factor could be calculated by estate and household income. Considering these two aspects, we suggested four alternatives for calculating the adjustment factor. Each alternative has its advantages and disadvantages from three perspectives: the size of the landlord’s rent income, the equity of the rent burden among tenants and the possibility of mixed-income housing. In the actual project stage, it will be necessary to select an appropriate alternative that meets the policy direction.
