Based on data from the Central Statistics Agency (BPS), the population of Cilacap has increased by 300,282 people over the past five years. With rapid population growth, the need for housing is becoming increasingly difficult to meet. The Ministry of Public Works and Public Housing (PUPR) is committed to building public housing as a solution to this problem. However, to ensure that these buildings are livable and sustainable, it is important to conduct a comprehensive cost analysis. In construction projects, life cycle cost analysis is one of the efforts to prepare for the need to understand that costs are not limited to the construction phase. Construction projects often only consider initial costs, which can lead to errors in long-term financial planning. Life Cycle Cost Analysis helps in long-term planning, enabling decision-makers to consider all aspects of costs that will arise throughout the building's lifespan. This not only improves budget efficiency but also ensures that residents receive adequate housing facilities. Therefore, it is necessary to conduct research on the economic value analysis of a building, specifically in the form of life cycle cost planning, for a low-cost apartment building with a 25-year lifespan. This analysis should encompass initial costs, operational costs, and maintenance and replacement costs. This research is quantitative. The method used is life cycle cost. Data collection methods include field observations and interviews. The research results indicate that the life cycle cost (LCC) planned for a 25-year lifespan amounts to Rp 20,486,745,640, comprising initial costs of Rp 13,446,741,389 (54.07%), operational costs of Rp 5,832,349,683 (23.45%), maintenance costs of Rp 1,940,837,459 (7.80%), and replacement costs of Rp 3,649,042,776 (14.67%).
