Buildings that operate without a structured preventive maintenance checklist spend 4.8x more per emergency repair and face 2.4x higher tenant turnover. This system-by-system checklist gives facility and property managers every critical inspection task — with timing, priority, and responsible party mapped to each item. Book a demo to see how Oxmaint auto-schedules every item on this checklist across your entire portfolio.
Oxmaint Compliance Coverage by Region
A preventive maintenance checklist is only effective if it aligns with the inspection frameworks your jurisdiction requires. Oxmaint maps PM schedules to regional compliance standards and auto-generates audit-ready documentation for every completed task. See how Oxmaint handles your region's compliance requirements in a live walkthrough.

How to Use This Checklist
This checklist is organized into six building system categories. Each task includes a recommended frequency, a priority level, and the responsible party. Tasks marked Critical must not be deferred — they directly prevent equipment failure or regulatory citations. Tasks marked High should be completed within each scheduled interval window. Walk through how Oxmaint loads this checklist directly into your PM schedule in a 30-minute demo.
Checklist 1: HVAC and Central Plant
HVAC systems account for 84% of reactive maintenance spend in commercial buildings. A missed filter change or deferred coil cleaning routinely escalates into a $3,500-$8,500 compressor failure. Pre-scheduled HVAC PM reduces emergency callouts by 45% and extends equipment life by 3-5 years. See how Oxmaint auto-assigns HVAC PM tasks to technicians on a fixed interval schedule across your entire building portfolio.

Checklist 2: Plumbing and Water Systems
Plumbing failures account for 72% of preventable emergency water damage in commercial buildings. A single undetected pipe failure causes an average of $18,000 in direct repair and remediation costs — not including lost rent or tenant claims. Every task on this checklist is a documented line of defense against that figure. Book a demo to see how Oxmaint tracks plumbing asset condition and PM status across a multi-building portfolio.

Checklist 3: Electrical and Lighting Systems
Electrical failures account for 63% of preventable emergency electrical spend in commercial buildings. Missed panel inspections and deferred thermal imaging scans are the leading cause of unplanned shutdowns and insurance claim complications. See how Oxmaint schedules electrical PM tasks and captures inspection findings asset-by-asset in a live demo.

Checklist 4: Fire Safety and Life Safety Systems
Regulatory citations for missed fire safety inspections average $12,000-$18,000 per finding. 60% of commercial buildings fail at least one annual fire safety audit — a direct result of undocumented or inconsistently executed PM programs. Book a demo to see how Oxmaint tracks life safety compliance tasks with auto-generated audit documentation.

Checklist 5: Elevators and Vertical Transport
Elevator downtime in a commercial building costs an average of $1,200 per hour in tenant disruption and lost productivity.
