What should be on a commercial building preventive maintenance checklist?
Build it around four rhythms: a monthly walk-through, seasonal heating and cooling service, an annual round of life-safety checks, and a log of every repair. Cover exits and emergency lighting, fire extinguishers, floors and walkways, filters and condensate drains, and leaks. Staff can do the walk-through; licensed trades handle systems.

Step by step
Read when to stop and call a pro, further down this page, before you start.
Step 1: Walk the building monthly
Once a month, walk every room, the exits, the restrooms and the exterior with this checklist and a phone for photos.
Step 2: Check the exit routes
Confirm exit routes are free and unobstructed, that nothing is stored in them, and that every exit is clearly visible and marked.[1]
Step 3: Test the safeguards you can see
Look at sprinkler heads, alarm panels, fire doors and exit lighting for damage or blocked access, and report any that are not in proper working order.[1]
Step 4: Inspect the extinguishers
Look at each extinguisher monthly for easy access, a readable label, an intact pin and a gauge in the green, and write the date on the tag or log.[2]
Step 5: Check floors and walkways
Look for loose boards, corrosion, leaks, spills, snow and ice, and guard or repair any hazard before anyone uses the surface again.[3]
Step 6: Change or clean the air filters
Inspect, clean or change air filters once a month, or as the equipment maker directs.[4]
Step 7: Look for water
Check ceilings, under sinks, around the water heater and near the condensate drain for stains, drips and damp; dry any wet area within 24 to 48 hours.[5]
Step 9: Keep the log
Record the date, what you found, who fixed it and what it cost, so patterns show up and vendors can be held to their work.
A good preventive maintenance checklist runs on four rhythms: a monthly walk-through, seasonal heating and cooling service, an annual round of life-safety checks, and a written log of every finding and repair. Cover the exits, fire extinguishers, floors and walkways, air filters and drains, and any sign of water. Staff can do the walk-through; licensed trades handle the systems.
Below is a checklist you can adapt to an office, shop or small commercial building, and where the work stops being yours.
The monthly walk-through
Take twenty minutes with a printed list and a phone for photos. Go through the same route each time so changes stand out.
Exits and emergency equipment. Exit routes must be free and unobstructed. No materials or equipment may be placed, either permanently or temporarily, within the exit route.[1] Check that exits are lit and marked with a sign reading "Exit".[1] Safeguards designed to protect employees during an emergency (e.g., sprinkler systems, alarm systems, fire doors, exit lighting) must be in proper working order at all times.[1] You cannot service them yourself, but you can see a blocked fire door, a dark exit sign or a damaged sprinkler head and report it that day.
Fire extinguishers. Portable extinguishers or hose used in lieu thereof under paragraph (d)(3) of this section shall be visually inspected monthly.[2] Look for clear access, a readable label, an intact pin and a gauge in the green, and note the date.
Floors and walkways. Walking-working surfaces are inspected, regularly and as necessary, and maintained in a safe condition.[3] Walking-working surfaces are maintained free of hazards such as sharp or protruding objects, loose boards, corrosion, leaks, spills, snow, and ice.[3] Check entry mats, stair edges, handrails, lot surfaces and lighting at the doors too.
Filters and drains. Inspect, clean, or change air filters once a month in your central air conditioner, furnace, and/or heat pump.[4] ENERGY STAR writes that advice for homes, but the principle holds for small commercial units: follow the equipment maker's schedule. Look at the condensate drain as well. A plugged drain can cause water damage in the house and affect indoor humidity levels.[4]

Water. Check ceilings, under sinks, near the water heater and by exterior walls for stains, drips and damp. It is important to dry water-damaged areas and items within 24-48 hours to prevent mold growth.[5]
Seasonal and annual items
- Spring and fall heating and cooling service. Contractors get busy once summer and winter come, so it's best to check the cooling system in the spring and the heating system in the fall.[4] That visit covers coils, controls, drains and, for fuel-burning equipment, connections and burners, which are not do-it-yourself work.
- Annual extinguisher maintenance. The employer shall assure that portable fire extinguishers are subjected to an annual maintenance check.[2] Hire a service company, and keep the tag and invoice.
- Roof, gutters and drainage. Have a roofer look at the roof and flashing once a year and after major storms, and clear gutters and downspouts from the ground or have a vendor do it.
- Alarm, sprinkler and emergency lighting testing. Ask the company that maintains them what they test and how often, and request the report in writing.
- Parking lot and exterior. Walk the lot for potholes, faded striping, trip edges and failing lights each season.
Keep a log
A one-page log is enough: date, location, what you found, who was called, what was done and the invoice amount. After a year it shows which system is failing, which vendor is slow and what to budget. For typical spend, read how much facility maintenance costs for a small business in Virginia.
Who does what
A sensible split is simple. Staff do the walk-through, the filter swap, the extinguisher look-over and the log. Vendors do the scheduled service. Licensed people do anything on the building's systems: no individual may work as a tradesman unless licensed, except when working under the supervision of a tradesman licensed in that specialty.[6] If you are weighing a vendor against in-house help, read whether a small business should outsource facility maintenance. Your lease decides which items belong to the owner and which to you, so build the list around your side.
Stop and call a pro if
- You smell gas or smoke, or see sparks. Leave the building and call 911 or the utility from outside.
- An exit is blocked, locked or unlit and you cannot clear it safely. Treat it as urgent and get it fixed before the next shift.
- A leak, stained ceiling or damp wall keeps coming back. A licensed plumber or roofer should find the source.
- An alarm, sprinkler or extinguisher is out of service. Call the company that maintains it and arrange alternate protection until it is back.
- A heating and cooling unit trips, short-cycles or smells. Turn it off and call a licensed technician.
- The work involves electrical panels, gas lines or refrigerant. Use a licensed tradesman.[6]

Common questions
- How often should a commercial building be inspected?
- Walk it monthly, service heating and cooling in the spring and fall, and do the life-safety items on their own schedules: extinguishers are inspected monthly and get an annual maintenance check. Fix hazards on the floors and walkways as soon as you find them.
- Who should do the checklist items?
- Staff can do the walk-through, the filter change, the extinguisher look-over and the log. Anything on electrical, plumbing or heating and cooling systems belongs to a licensed tradesman, since no individual may work as a tradesman unless licensed, except when working under the supervision of a tradesman licensed in that specialty.
- How long should I keep inspection records?
- OSHA requires the annual extinguisher maintenance date to be recorded and kept for one year after the last entry or the life of the shell, whichever is less. Keeping every inspection and repair in one log, for longer, also helps with insurers, landlords and vendor disputes.
- What should I do about a small roof or ceiling leak?
- Stop the water if you safely can, move contents away, and dry the area within 24 to 48 hours, since EPA says that is what prevents mold. Then call a licensed roofer or plumber to find the source; do not go on the roof yourself.
- Does a tenant or the owner do the maintenance?
- It depends on the lease. Read which items the owner keeps up and which fall to you, and build your checklist around yours. The employer's duties for exits, extinguishers and walking surfaces apply to the space your employees use.
