How to Use This Checklist

  • **Complete the audit section first.** Record the date of the inspection, who prepared it and the location so the results are traceable.
  • **Work through each section in order.** Go through lighting, electrical, safety, HVAC, building interior, building exterior and plumbing, answering every question as you inspect the relevant area.
  • **Verify, don't assume.** For each item, look at the fixture, component or area and confirm its actual condition rather than relying on the last inspection.
  • **Answer honestly using the three-point scale.** Mark 'Yes' when a point is satisfactory, 'No' when it is not, and 'N/A' when the item does not apply to your building.
  • **Carry out the maintenance the questions call for.** Replace air filters and detector, torch and testing-instrument batteries; clean air intakes, motors, ducts, roof, drains and gutters as needed; drain condensate properly; remove plants growing on the structure and clear roof debris.
  • **Record what needs fixing.** Note any item marked 'No' or any point that requires repair — worn or damaged cables, loose fittings, torn ductwork, refrigerant line damage, broken windows or doors, waste accumulation or signs of infestation.
  • **Assign corrective actions during the inspection.** Give each task to the right person while you are still on site, so responsibility and timing are clear.
  • **Monitor the work to completion.** Check that open items are closed out before the next scheduled inspection, and use the completed checklist as the record of what was found and done.

Overview and preparation

Preventive maintenance in office buildings means regularly inspecting the building's systems and areas before problems get worse. Instead of reacting only when something fails, you work through a defined set of points, check the actual condition of each one and record the result. This checklist supports that work in eight sections (audit, lighting, electrical, safety, HVAC, building interior, building exterior and plumbing) and helps you identify problems, prioritize corrective actions, assign tasks to the right team during the inspection and track progress. Start with the audit section and record the date, who prepared the inspection and the location. Throughout all sections, each point is answered with one of three options: **Yes**, **No** or **N/A** (not applicable). This fixed scale keeps inspections consistent and makes it possible to compare results and track whether problems are being resolved.

Lighting and electrical systems

Lighting is one of the most visible areas of preventive maintenance. Check that all lights and bulbs work and none need replacing, that fixtures with transformers, control gear or accessories (diffuser lenses, glare baffles, color filters) are in good condition, and that outdoor lights and cables are not torn and all hardware and screws are in place. Also confirm that all emergency and exit lighting, interior lighting and exterior lighting is properly installed and working. This area also includes replacing the batteries in smoke and carbon monoxide detectors, flashlights and test instruments, and checking that timers and photocells work. On the electrical side, confirm that all hardware and electrical connections are in good condition, that controls and equipment have been tested and are safe, and that guards and access panels are secured and not loose.

Safety and emergency

Safety is handled as a set of specific checks: - First aid kit inventory checked and items restocked. - Eyewash bottles and stations checked. - Safety signs and equipment labels in good condition. - Respirators inspected and cleaned. - Harnesses and fall protection kits inspected. - Smoke and carbon monoxide detectors tested and working. - Fire alarm system tested and working. - Firefighting equipment in good condition. - Doors working properly and exits unobstructed. - Door locks and latches in good condition. - Work areas and walkways properly marked. The inspection should also confirm that floors, ceilings and walls show no signs of deterioration, that there are no visible signs of leaks and that no electrical, mechanical, structural, physical, tripping or other hazard has been identified.

HVAC (heating, ventilation and air conditioning)

HVAC covers several of the most technical points. Check the air intake and replace air filters as needed, clean motors and ducts as needed, and confirm that running blower motors show no excessive noise or vibration. Flexible duct connectors should be checked, the condensate drain pan should drain properly, and guards and panels should be secured. The indoor unit should work properly, and on the condenser side the condenser motor bearings should be checked for excessive noise or vibration, along with the condenser air intake, discharge and coil. All refrigerant lines and insulation should be in good condition, and guards or access panels secure and not loose. The outdoor unit should be in good working order.

Interior, exterior, telhado e estacionamento

Inside the building, confirm that faucets, toilets and showers are in good working order, that no trash builds up in storage areas, that there is no evidence of insect infestation, that cart wheels show no wear and that shelves are labeled, organized and secure. Also check the condition of paint and walls, the absence of broken windows or doors, the condition of grilles and that no plants are growing on the building or its foundation. Outside, the focus is on the roof and gutters: the roof should be cleaned as needed and in good condition; drains and gutters should be clean and tested by flushing them with water; gutters should be properly anchored and tightened if necessary. The chimney and all roof penetrations should be inspected, and there should be no plants growing on the roof and no accumulated debris. Plumbing completes the set, with a check of the working condition of faucets, toilets and showers and an inspection of compressed air lines for leaks in piping, tubing or fittings. Air filter elements should be replaced or cleaned at least quarterly, or as needed, and oil levels in air compressor pumps monitored and changed according to use.

What to do with the results

Marking a point as **No** does not end the job: identify the problem, define the corrective action and assign it to the right person during the inspection. Some points require immediate action as soon as they are found, such as removing plants growing on the building or roof and clearing debris. Others, such as replacing air filters, cleaning ducts and flushing gutters, are done as needed. Use the completed checklist as a record of what was found and what was done, track corrective actions until they are completed and repeat the inspection regularly. This standardized routine is what reduces failures and increases asset safety and reliability.

Frequently Asked Questions

A preventive maintenance checklist is a standardised set of checks your facilities team works through on a regular schedule. It groups the building's systems into sections — such as lighting, electrical, safety, HVAC and plumbing — and asks a defined question for each point so nothing is overlooked. The same checks are run each time, which is what makes the results comparable and the routine repeatable.

Without a written routine, problems tend to be found only after something fails — a light that is out, a leak, an obstructed exit or a smoke detector with a flat battery. Working through the checklist lets you identify issues, prioritise corrective actions, assign tasks to the right team member during the inspection and monitor progress. Over time this standardises routines, reduces breakdowns and raises the safety and reliability of the asset.

The checklist covers eight areas: an audit section for recording who conducted the inspection, where and when; lighting, including emergency and exit lighting; electrical systems; safety and emergency equipment; HVAC; the interior of the building; the exterior, roof, gutters and parking; and plumbing. It also asks you to record hazards found and whether housekeeping, storage and pest conditions are satisfactory.

Start with the audit section and record the date, who prepared the inspection and the location. Then work through each section in turn. Answer 'Yes' when a point is satisfactory, 'No' when it is not, and 'N/A' when the item does not apply to your building. Where the checklist asks you to act — replacing air filters, cleaning drains and gutters, removing plants or clearing debris — note when it was done or raise a corrective action. Assign follow-up tasks to the right person as you go and review the open items afterwards.

Three answer options are used throughout: 'Yes' for a point that passes, 'No' for one that fails and needs action, and 'N/A' where the item does not apply. The fixed scale keeps the results consistent across inspections so you can compare them and track whether problems are being closed out.

The lighting and electrical sections ask you to verify that all interior, exterior, emergency and exit lighting is installed and working, that fixtures with transformers, control equipment or accessories are checked, and that external lights and cables are not torn and all screws and fittings are in place. You also check that smoke and carbon monoxide detector batteries, torches and testing instruments have been replaced, and that timers and photocells are working correctly.

The safety section covers first aid kit inventories and replenishment, eyewash bottles and stations, the condition of safety signs and equipment labels, inspection and cleaning of respirators, and inspection of harnesses and fall protection kits. It also asks whether smoke and carbon monoxide detectors, the fire alarm system and firefighting equipment have been tested and are working, whether all doors operate properly with exits unobstructed, and whether locks and latches are in good order. Other points cover floor, ceiling and wall deterioration, visible leaks, and whether the inspection found any electrical, mechanical, structural, physical or trip hazard.

The HVAC section walks through the air handling system: air intakes cleaned and air filters replaced as needed; blower motors checked for excessive noise or vibration; motors and ducts cleaned; condensate drain pans draining properly; flexible duct connectors checked; guards and panels secure; electrical hardware and connections in good condition; controls and equipment tested and safe; and the indoor unit operating correctly. It then covers the condensing unit — bearing noise and vibration, the condensing air inlet, discharge and coil, refrigerant lines and insulation, and secure access guards and panels.

Yes. The plumbing section asks whether taps, toilets and showers are in good working condition, and a separate section on air compressors covers air lines for leaks in piping, tubing and connections, replacement or cleaning of air filter elements at least quarterly or as needed, and monitoring and replacement of oil levels in air compressor pumps depending on use.

The exterior section covers the roof — cleaned as needed, in good condition, with drains and gutters cleared and tested with water, gutters properly anchored and tightened where needed, and the chimney and all roof penetrations inspected. It also checks for plants growing on the roof or on the building and its foundation, and for debris that needs clearing. Separately it covers windows and doors, the condition of fence rails, the removal of waste accumulation in storage areas, and evidence of insect infestation.

All are presented as plain inspection points, but several items note a frequency in the question itself — for example, air filter elements are replaced or cleaned at least quarterly or as needed, and oil levels in air compressor pumps are monitored and replaced as needed depending on use. Other points, such as cleaning air intakes, motors, ducts and the roof, are marked 'as needed', so the right interval depends on your building and how it is used.

The electrical section asks whether all electrical hardware and connections are in good condition and whether controls and equipment have been tested and are safe. It also asks whether guards and access panels are secure and not loose. The audit section records who carried out the inspection, where and when, so findings can be attributed. The checklist does not name a specific electrical standard or regulation.

The audit section records the date of the inspection, who prepared it and the location. As you work through the sections, note any item answered 'No' or any point requiring action, assign the corrective task to the appropriate team member during the inspection, and monitor progress until the item is closed out.
