How to Start a Commercial Cleaning Business
Cleaning offices, retail spaces, medical-adjacent suites, gyms and other commercial properties, often after hours and on a recurring contract.
Who it suits
People who like structure and systems, can manage schedules and staff, and are comfortable with written bids and contracts.
How people get started
Owners often move into commercial work after residential, starting with small offices and bidding larger contracts as they add staff.
Step-by-step plan
- Pick the types of facilities you'll serve and what they typically need.
- Learn to do a walkthrough: measure areas, note floor types, restroom counts and frequency.
- Estimate production time by area type using your own timed work.
- Get insurance and any bonding commercial clients ask for.
- Build a professional proposal template with scope by frequency.
- Decide how you'll staff and supervise night work.
- Bid smaller accounts first and build references.
- Set up a quality inspection checklist and use it.

Licensing pointers
Check local business licensing. Commercial clients often require proof of insurance and sometimes bonding before you can bid.
OSHA's Hazard Communication standard applies to employers whose workers use hazardous chemicals (osha.gov/hazcom). Check specialized requirements before cleaning medical or food spaces.
Rules vary by state, county and city. Confirm with your state board or agency before you start. This isn't legal advice.
