How to Use This Checklist
- **Record the basics.** Note the date the inspection was conducted, who prepared it and the location. This gives you a record you can compare against future visits.
- **Work through each area in turn.** Move through lighting, electrical, safety, HVAC, building interior, building exterior and plumbing. The checklist keeps the same order every time, so a visit does not drift.
- **Flag and assign as you go.** When an item fails, note it and assign the fix to the right person or team straight away. The checklist is designed for tasks to be allocated during the inspection, not after it.
- **Where an item does not apply, mark it N/A.** Not every building has the same equipment, and the checklist allows for that.
- **Confirm the recorded state.** The questions are phrased as conditions — lights have been checked and none need replacing, the fire alarm system has been tested and is working — so a Yes means you have verified it, not simply that you looked.

Why preventive maintenance matters
A building that is only repaired when something breaks costs more to run and is less safe to work in. Preventive maintenance is the practice of inspecting and servicing systems on a schedule so that small problems — a worn door closure, a clogged filter, a slow drain, a light that needs replacing — are found and fixed before they grow into failures, leaks or hazards. The value is in the routine. When you inspect regularly and record what you find, you build a picture of how the building is actually behaving: which systems need attention more often, where waste is accumulating, whether equipment is getting noisier or looser. That record is what lets you plan work and budget rather than react to emergencies. The foundational checks are the lighting and electrical systems. The checklist asks you to confirm that all lights, bulbs and lamps have been checked and none need replacing; that internal, external and exit lights are correctly installed and functioning; that luminaires with transformers, control devices or accessories have been checked; that outdoor lights and cables are not torn and all screws and hardware are in place; and that timers and photocells are working. It also covers practical details such as replacing batteries in smoke and carbon monoxide detectors, flashlights and test instruments, and checking that cover plates show no cracks and are properly tightened. All exhaust fans should be clean. Safety equipment is treated with the same rigour. The checklist covers first-aid kits (inventoried and restocked), eyewash bottles and stations, safety signs and equipment labels, respirators (inspected and cleaned) and harnesses and fall-protection kits. These items are easy to overlook until they are needed, which is exactly why they belong in a scheduled inspection.
What a good inspection covers
A preventive maintenance inspection of an office building should cover the systems and structures that affect safety, comfort and the fabric of the building itself. **Heating, ventilation and air conditioning.** The checklist works through the air intake, air filters, blower motors, motors and ducts, the condensate pan, flexible duct connectors, guards and panels, hardware and electrical connections, controls and equipment, and the indoor and outdoor units. It checks condenser motor bearings for excessive noise or vibration, inspects the air inlet, discharge and condenser coil, and confirms that refrigeration piping and insulation are in good condition. **Compressed air systems.** Where these are present, the checklist covers the lines themselves — no leaks in piping, lines or fittings — as well as air filter elements, which should be replaced or cleaned at least once per quarter or as required by the application, and oil levels in the compressor pump, checked and replaced as necessary depending on use. **The building interior.** Floors, ceilings and walls should show no signs of deterioration, and there should be no visible leaks. The inspection should reveal no hazards — electrical, mechanical, structural, physical or trip hazards. Faucets, toilets and showers should be operational and in good working condition. Smoke and carbon monoxide detectors, and the fire alarm system, should be tested and working, and firefighting equipment should be in good condition. All doors should be in good working order with exits unobstructed, door locks and closures in good condition, work areas and aisles properly marked, storage areas free of waste accumulation, and no signs of insect infestation. Cart casters should show no wear and shelves should be properly labelled, organised and secured, and paint and walls should be in good condition. **The building exterior.** The checklist covers broken windows or doors, the condition of handrails, and whether plants are growing on the building or its foundation. The roof should be cleaned if necessary — working cautiously at height with adequate fall protection — and roof drains and gutters cleaned, with drains and downspouts tested by flushing with water. The roof itself should be in good condition, gutters properly secured and tightened if necessary, and the chimney and all roof penetrations inspected. No plants should be growing on the roof, and no debris should be present. **Plumbing.** There should be no visible leaks, and faucets, toilets and showers should be operational and in good working condition.
How to carry out the inspection
A preventive maintenance inspection is only useful if it is done consistently. The steps below follow the structure of the checklist. 1. **Set the scope and record the basics.** Note the date the inspection was conducted, who prepared it and the location. This is the record you will compare against next time. 2. **Start with lighting and electrical.** Confirm that all lights, bulbs and lamps have been checked and none need replacing, that indoor, outdoor and exit lights are correctly installed and functioning, and that outdoor lights and cables show no tearing with all screws and hardware present. Check timers and photocells, replace batteries in detectors, flashlights and test instruments, and confirm that cover plates show no cracks and are properly tightened. Clean all exhaust fans. 3. **Check safety equipment.** Inventory and restock first-aid kits, check eyewash bottles and stations, inspect safety signs and equipment labels, inspect and clean respirators, and inspect harnesses and fall-protection kits. 4. **Work through HVAC and compressed air.** Confirm the air intake has been cleaned if necessary and that air filters have been replaced if necessary. Listen to blower motors for excessive noise or vibration, clean motors and ducts if necessary, confirm the condensate pan drains properly and check flexible duct connectors. Confirm guards and panels are fastened and not loose, and that hardware and electrical connections are in good condition. Test controls and equipment for safety, confirm the indoor unit is operating correctly, and check the condenser motor bearings for noise or vibration. Inspect the air inlet, discharge and condenser coil, and confirm refrigeration piping and insulation are in good condition. For compressed air, inspect lines for leaks, replace or clean filter elements at least once per quarter or as required, and check and replace oil levels as necessary. 5. **Walk the interior.** Check floors, ceilings and walls for deterioration and look for visible leaks. Confirm the inspection reveals no hazards. Check plumbing fixtures, test smoke and carbon monoxide detectors and the fire alarm system, confirm firefighting equipment is in good condition, and check doors, locks and closures for good working order with exits unobstructed. Confirm work areas and aisles are properly marked, storage areas are free of waste accumulation and there are no signs of insect infestation. Check cart casters and shelving, and the condition of paint and walls. 6. **Walk the exterior.** Check for broken windows or doors and the condition of handrails, and look for plants growing on the building or its foundation. Clean the roof if necessary — with adequate fall protection — and clean roof drains and gutters, testing drains and downspouts by flushing with water. Confirm the roof is in good condition, gutters are properly secured and tightened if necessary, and inspect the chimney and all roof penetrations. Remove any plants growing on the roof and clear any debris. 7. **Assign and track.** As you identify problems, assign each one to the appropriate team or staff member immediately, even while the inspection is still in progress. That way nothing flags on the list and then sits unattended, and you can see progress as the work is closed out.
Who should use this checklist
This checklist is for anyone responsible for keeping an office building in good working order — facilities and property managers, maintenance teams, building supervisors and the contractors who carry out scheduled servicing on their behalf. It is designed for routine, planned inspections rather than emergency call-outs, and it works whether you are responsible for one building or a portfolio. You do not need to be a qualified engineer to use it. Most items are observational: a light that does not work, a door that does not close properly, a drain that does not flow, a leak that is visible, debris that has collected. Where an item calls for hands-on work — cleaning a roof, testing a fire alarm system, servicing a compressor — it should be carried out by someone competent to do it, with the right equipment and, for work at height, adequate fall protection. The checklist assumes a building with the systems listed: lighting, electrical equipment, fire and life safety equipment, HVAC, compressed air and plumbing. Where a building does not have a particular system, mark the item N/A rather than leaving it blank, so the record is clear.
Building the inspection into your routine
A single inspection tells you the state of the building on one day. The real benefit comes from doing it regularly — monthly, quarterly or annually depending on the system and the building — and comparing what you find each time. The checklist supports that rhythm in a few ways. It keeps the same structure, so each visit covers the same ground and you can see changes over time. It records the date, who prepared it and the location, so each inspection has an owner and a place in the sequence. It prompts you to assign issues immediately, which turns a list of observations into a set of actions. And because it is answered Yes, No or N/A, a completed inspection is quick to read: the items that need attention stand out. The section areas are a useful way to divide the work. If several people are involved, one can take lighting and electrical, another HVAC and compressed air, another safety, and another the interior and exterior walkthrough, with plumbing checked alongside the interior. However you split it, the audit section ties it together by recording when the inspection took place and who carried it out.
