808 janitorial services establishments are based in the Riverside-San Bernardino metro. 35 more opened over the past year, so buyers are fielding new names. The trade is 29% less concentrated than the U.S. as a whole, so a consistent outbound program reaches facility and office managers that are not tired of contractor calls. 3.7 larger cleaning-buying buildings per contractor puts Riverside 55 of 100 markets, and 6 of 11 in California. That sits mid-pack: real room to grow, but the best accounts are contested. If you can serve San Diego and Los Angeles, they have more larger buildings per contractor than Riverside.

Tier 1 covers manufacturing plants, ambulatory health care: physician, dental, outpatient and urgent care and senior living and skilled nursing with 50 or more people on site.
