If you manage multiple commercial buildings across Wayne, Oakland, or Macomb counties, you know cleaning problems rarely announce themselves. They build quietly until a tenant calls or a walkthrough reveals gaps between what you're paying for and what's getting done. A structured janitorial audit gives you the facts to hold any vendor accountable.
This guide walks through each part of a practical audit you can run across your Detroit-area properties. CJT Janitorial builds every cleaning plan around a written scope with defined tasks, frequencies, and a named point of contact, so audits like these are part of how we work.
What Should a Janitorial Audit Cover for Multi-Building Portfolios?
A janitorial audit compares what your vendor agreed to do against what actually happens in each building. It should cover the written scope of work, invoice accuracy, insurance and vendor documentation, building access logs, and tenant complaint history. Running these checks on a regular schedule keeps small gaps from turning into expensive problems across multiple properties.
- Scope vs. delivered work: Pull out the contract for each location. List every task and its agreed frequency. Walk the building and verify that restrooms, lobbies, offices, and common areas match the written plan.
- Invoice vs. frequency review: Compare monthly invoices to the task schedule. Flag any charges for work that wasn't performed at the stated frequency.
- Insurance and vendor documents: Confirm the vendor carries current general liability and workers' compensation coverage. Request a certificate of insurance and check expiration dates at least once a year.
- Access logs: If your buildings use key cards or sign-in sheets, review entry and exit times. These records show whether crews arrive on schedule and stay long enough to complete the scope.
- Complaint history: Compile every cleaning-related complaint from tenants over the past quarter. Look for patterns by building, floor, or area. Repeat issues in the same spot usually point to a missed task, not a one-time slip.
How Do You Audit Scope of Work Against Actual Cleaning?
Start with the written scope and walk each building after the crew has finished. Check high-traffic areas first: lobbies, restrooms, break rooms, and elevator landings. Compare what you see to the specific tasks listed in the contract. Dust on vents, full trash liners, or unstocked dispensers are signs that listed tasks are being skipped or rushed.
Bring a copy of the task list on a clipboard or phone. Mark each item pass or fail as you go. Over a few weeks, you'll see whether gaps are isolated or repeated. Repeated misses in the same areas across buildings suggest the crew is either understaffed or working without a clear checklist.
How Should You Review Invoices and Cleaning Frequencies?
Match every line item on the invoice to the agreed task schedule for that building. If the contract calls for carpet extraction quarterly and you haven't seen it done, that charge needs a conversation. Look for vague line items like "additional services" that don't tie back to a documented request from your side.
Fixed monthly proposals with a clear task-and-frequency breakdown make this step fast. When every task, frequency, and price is spelled out before work begins, invoice review takes minutes. At CJT Janitorial, we use written, facility-specific scopes so both sides know exactly what's included.
Why Do Insurance and Vendor Documents Matter in a Cleaning Audit?
A vendor working in your building without proper coverage puts your property at risk. Your audit should confirm that the cleaning company carries current general liability and workers' compensation insurance. Ask for a certificate of insurance naming your management company as an additional insured. Check that no policies lapsed since the last review.
Keep a file for each vendor that includes their insurance certificate, W-9, signed contract, and any licensing documents your properties require. Review it at least once a year and at contract renewal. CJT Janitorial makes its insurance certificate available on request, so there's never a delay when your compliance team needs documentation.
How Can Access Logs and Complaint History Improve Accountability?
Building access logs confirm whether crews show up when they're scheduled and stay long enough to complete the work. If, for example, a scope that should take a full evening consistently shows a visit half that long, you have a measurable gap between the plan and the delivery. This data pairs well with your walkthrough findings.
Tenant complaints fill in what walkthroughs miss. Sort them by building, floor, and area to spot patterns. A string of restroom complaints on the same floor means that area needs a closer look at the next audit. Tracking complaints over time shows whether corrective actions are sticking.
What Does a Practical Janitorial Audit Checklist Look Like?
A usable audit checklist fits on one page and covers scope, invoices, insurance, access logs, and complaint patterns. Print one per building and fill it out during your walkthrough. Over a few quarters, these completed checklists become a documented record of vendor performance you can reference during contract renewals.
- Scope review: Written scope on file for each building? All listed tasks observed during walkthrough?
- Invoice check: Every invoice line item matches a contracted task? No unexplained charges?
- Insurance: Current certificate of insurance on file? Expiration dates comfortably in the future?
- Access logs: Crew arrival and departure times match scheduled hours? Visit duration consistent with scope?
- Complaints: All complaints from the last quarter reviewed? Patterns identified and flagged?
- Corrective actions: Open items from the previous audit resolved? Resolution documented?
Run this checklist quarterly at a minimum. For high-traffic buildings or medical facilities, monthly reviews keep standards tighter.
Frequently Asked Questions
How often should property managers audit janitorial vendors?
Quarterly audits work well for standard office buildings. Medical facilities, high-traffic lobbies, and buildings with frequent tenant turnover benefit from monthly reviews. The key is consistency. Pick a schedule and stick with it so patterns become visible over time.
What is the most common issue found during a janitorial audit?
Gaps between the written scope and the work actually performed. Tasks listed as weekly that happen biweekly, or areas skipped entirely, are the findings that come up most often. A written task-and-frequency scope makes these gaps easy to identify.
Should the cleaning vendor be present during the audit?
It depends on the goal. Unannounced walkthroughs show day-to-day performance. Joint walkthroughs with the vendor work well for setting expectations or resolving ongoing issues. Both have a place in a solid audit routine.
What documents should a janitorial company provide on request?
At a minimum: a certificate of insurance, a written scope of work for each location, and a named point of contact. CJT Janitorial keeps all of these ready so you never have to chase paperwork during an audit or compliance review.
How do you handle a vendor that fails the audit?
Document the specific gaps, share the findings in writing, and set a clear timeline for corrective action. If the same issues appear again at the next audit, it may be time to get proposals from other local cleaning partners and compare scopes side by side.
