As large-scale redevelopment projects are limited, small-scale renewal projects are attracting attention. In order to substantially improve the residential environment in the areas where the redevelopment promotion zone has been lifted, it is necessary to introduce a small-scale renewal project. This study is to establish renewal alternatives in consideration of the block-type residential type characteristics of the target site, review the feasibility of the renewal alternatives through business balance review, and present implications. First, eight alternatives were set in consideration of the size and location of the existing complex and the size of unit households. Second, the business balance review was set in 6 stages. As a result of the proportional ratio and contribution analysis, the 3 and 4 plans for both A and B types are advantageous, and the B type is more advantageous as a result of the contribution per same area analysis. Third, as a result of reviewing in terms of maintenance effectiveness, spreadability, and ease of installation of parking lots, it was concluded that the B-4 plan was advantageous. According to the previous results, in order to activate small-scale maintenance projects, it is necessary to upgrade at least one level and to relax related regulations so that an acceptable contribution is possible.
