Against the background of the continuous promotion of urban renewal and quality improvement of stock assets in China, the number of housing maintenance and renovation projects is growing rapidly. These projects are characterized by large differences in single-unit scale, complex on-site conditions, frequent changes and visas, and high difficulty in cost control. The traditional static cost management model is difficult to adapt to the uncertainty of the whole life cycle of maintenance and renovation projects, which is prone to problems such as over-budget, low efficiency and unreasonable resource allocation. To improve the economic efficiency and refinement of project management, this paper takes housing maintenance and renovation projects as the research object, based on the whole-cycle management theory and dynamic cost control ideas, combs the cost composition and control points of each stage of the project, adopts literature research, case analysis and dynamic tracking methods to identify the core pain points of current cost control. The study constructs a dynamic cost control system covering the whole project cycle, puts forward targeted cost optimization strategies, verifies its effectiveness with actual cases, provides theoretical reference and practical path for similar projects, and promotes the transformation of projects from passive accounting to active control.
