Principals: Here’s a Ten-Item Checklist to Assess the Health of Your School Building

by Michael Keany

November 2026

Principals spend enormous amounts of time assessing instruction, student achievement, attendance, behavior, and school culture. But there is another important question worth asking regularly:

How healthy is the building itself?

A school building affects far more than appearances. Ventilation, cleanliness, temperature, lighting, moisture, noise, and maintenance can influence student comfort, staff morale, attendance, and the ability to concentrate. The U.S. Environmental Protection Agency emphasizes that good operations and preventive maintenance are essential to keeping school environments healthy and functioning effectively.

A principal does not need to become an engineer or facilities expert. But every principal should periodically walk the building with fresh eyes—and preferably with the head custodian or facilities director.

Here is a ten-item checklist.

1. What does the building smell like?

Pay attention immediately upon entering classrooms, bathrooms, locker rooms, cafeterias, basements, and storage areas. Musty or unusual odors can signal moisture, inadequate ventilation, plumbing problems, accumulated waste, or other conditions requiring investigation.

2. Is the air comfortable?

Visit classrooms at different times of day. Are some consistently too hot, too cold, stuffy, or humid? Ask teachers whether conditions change when classrooms are full. EPA guidance identifies effective HVAC operation and adequate outdoor-air ventilation as important components of healthy indoor environments.

3. Is there evidence of water?

Look above ceiling tiles, around windows, beneath sinks, near exterior doors, and along walls. Water stains, peeling paint, warped materials, damp carpeting, or visible mold deserve prompt attention. Moisture problems can worsen quickly if ignored.

4. How clean is the school—really?

Do more than inspect shiny hallway floors. Look behind furniture, on vents, along window ledges, in stairwells, under cafeteria tables, and inside frequently used common areas. Cleanliness communicates expectations, but it also contributes to environmental health.

5. Are bathrooms fully functioning?

Check faucets, toilets, soap dispensers, hand dryers or paper towels, stall doors, ventilation, odors, and overall cleanliness. Students quickly notice whether adults tolerate broken or poorly maintained facilities.

6. Are classrooms well lit?

Look for burned-out lights, glare, excessively dark rooms, blocked windows, and inconsistent lighting. Then ask the most important question: Can students comfortably see what they are expected to read, write, build, or examine?

7. What is the noise level?

Listen for HVAC systems that roar, buzzing fixtures, hallway echoes, exterior equipment, or neighboring spaces that interfere with instruction. Environmental conditions should support—not compete with—teachers and students.

8. Are entrances, exits, and pathways safe?

Walk the school as though you were unfamiliar with it. Are emergency exits clearly marked and unobstructed? Are stair rails secure? Are floor surfaces damaged? Are exterior walkways, steps, playground approaches, and parking areas in good repair?

9. Are maintenance problems being tracked—or merely noticed?

A recurring leak, broken door, malfunctioning thermostat, or damaged ceiling tile should not survive simply because everyone has become accustomed to it. EPA guidance recommends preventive-maintenance schedules and work-order systems that document problems, repairs, and recurring equipment issues.

10. What do the people who use the building say?

Perhaps the most valuable inspection tool is conversation.

Ask custodians, teachers, nurses, students, secretaries, cafeteria workers, and security staff: “Is there anything about this building that concerns you?”

They occupy different parts of the school at different times and often notice patterns administrators miss. EPA’s framework for school indoor-air-quality management specifically recommends walking the grounds, listening to occupants, establishing baselines, and communicating findings.

The Principal’s Building Walk

Consider conducting this ten-point inspection once each quarter.

Do not simply create a list of deficiencies. Identify each concern, assign responsibility, establish a completion date, and revisit unresolved items.

A healthy school building does not have to be new, luxurious, or architecturally impressive. Some excellent schools operate in very old buildings.

But healthy schools are noticed, maintained, monitored, and cared for.

And perhaps the simplest leadership test is this:

Would you be satisfied if your own child spent six or seven hours every day in this building?

If the answer gives you pause, your next leadership walkthrough may need to begin with the building itself.
