The average age of a main instructional school building in the United States is 49 years, according to a survey by the National Center for Education Statistics (NCES).
About 38% of schools were built before 1970. Roughly half of the schools surveyed have undergone a major building renovation or addition. Of those that have been renovated, the average age of the renovation was 14 years.
Major repair, renovation, or modernization work was being performed in 21% of all public schools surveyed as of December 2023. Indoor air quality is a major focus for many schools, with 39% having an indoor air quality coordinator on campus. This position is responsible for monitoring air quality conditions at the school and reporting air quality issues and complaints.
Some 60% of schools have designated vehicle loading and unloading areas at least 25 feet from all building air intakes, including doors and windows. Eighteen % of schools have an anti-idling program that includes signage and active monitoring during pick-up and drop-off times.
Some 31% of public schools have one or more non-permanent (portable) buildings in use.
