- There is no single legal standard, but there is a normal routine: nightly or several times a week for trash, restrooms and floors, with periodic deeper tasks.
- Industry groups such as ISSA publish cleaning standards and productivity guidance that many companies reference.
- Your written scope, not a general standard, is what you can enforce.
Many buyers ask what is "normal" so they can tell whether they are getting a fair deal. The honest answer is that there is no single law that defines it. There is, however, a common pattern.
The usual rhythm
- Daily or several nights a week: trash and recycling, restrooms, vacuuming or mopping, break room, entry and high-touch points.
- Weekly: dusting of reachable surfaces, detailed restroom work, glass and partitions.
- Monthly or quarterly: high dusting, vents, baseboards and spot treatment of carpet.
- Annually or as needed: carpet extraction, hard-floor refinishing and exterior windows.
Frequency should match traffic. A busy front office needs more attention than a small back-office suite.
Where the "standards" come from
The cleaning industry has recognized references. ISSA, the worldwide cleaning industry association, publishes the Cleaning Industry Management Standard (CIMS) for how cleaning organizations run, and productivity guidance such as cleaning time estimates. Many professional companies use these as a framework. They are guidelines for the business, not a contract with you.
OSHA rules also apply to cleaning companies and their workers, covering chemical hazard communication, protective equipment and bloodborne pathogens where relevant. See our disinfection basics guide.
What you can actually rely on
The standard you can enforce is the one written into your scope of work. If you want restrooms disinfected nightly and glass cleaned weekly, write it down.
