Commercial cleaning, or janitorial services, franchises benefit from multiple different revenue streams in the types of buildings they clean for, including corporate offices, schools, hospitals, retail spaces, and more. And though they are commercial, these franchises can offer services to homeowners as well.

One of the most popular franchise industries, the U.S. commercial cleaning and maintenance services industry is reported to bring in $117 billion annually across all of its franchised and non-franchised businesses.

Green, or environmentally-friendly, cleaning is of great importance within the commercial cleaning franchise industry, especially as more people have gained the desire to actively do the right thing for the Earth.
