Findings of a study that determined the physical conditions of Minnesota's public school buildings 50 years and older are presented in this report. Data were obtained from a survey that was distributed to 367 school districts that have 614 buildings 50 years and older. Responses were received from 398 buildings in 242 school districts. Findings indicate that buildings 50 years and older are in general usage statewide and that they present multiple inadequacies in applicable codes and standards including health and safety, handicapped access, and functional adequacy. Over 75 percent reported inadequate site sizes in which future expansion is limited. Recommendations are made to develop and implement a comprehensive statewide monitoring and inspection system, to assess the cost of building improvement, and to identify the adequacy and cost-effectiveness of funding resources. Six tables are included. Appendices contain the survey form and a list of responding schools. (Contains 7 references.) (LMI)
