Hospital buildings had a great importance in maintaining a healthy society free of disease, as it represents the national wealth great economic. Because of, high cost of construction for hospital buildings, so it must maintain its national wealth. The maintenance for hospital buildings has many benefits as, rising the service life for these building, decreasing the need for many works of substitution against negligence, and keeping these buildings away from dangerous of stopping and putting the lives of patients at risk. With no doubt, ignoring the study of maintenance for hospital buildings leads to many problems as, prevented hospital buildings to perform its role in Community Service, deterioration that occurs in the health of buildings (so to speak), increasing risk for life for Patients, Also this leads to a lot of wasted public money, including the impact on the economy, especially in developing countries. The real problem of maintenance for hospital buildings, lies in the failure of following scientific methodology to post-occupancy evaluation for hospitals to improve the efficiency of maintenance. Therefore, the aim of this research is to develop a method for development of the maintenance plan, in order to improve the efficiency of maintenance work in hospitals through the judgment on the performance of its through various elements after occupancy, So we can determine the maintenance and renewal required, in order to achieve the highest health service and social return and investment in the context of the circumstances and possibilities in each hospital. Also, this research highlight on the importance of maintenance for buildings and the importance of post-occupancy evaluation in general and specially for hospitals. The analysis under consideration is perform for hospitals, with a method to the development of maintenance plans in hospitals to improve the efficiency of maintenance work for these building, through the judgment on the performance of its with various elements after occupancy, Then suggest the proposed approach of hospital maintenance to demonstrate the importance of the these elements. Finally, this research suggests a mechanism for improving maintenance of hospital buildings, to rise the efficiency of maintenance in hospitals, through a questionnaire process for the important of elements take into account in this research, the results were perfectly matched what was covered in this research results.
