1. Residential vs Commercial: The Fundamental Shift
Transitioning from residential cleaning to commercial janitorial work offers huge benefits: predictable recurring monthly revenue, night-time cleaning without client interruption, and long-term multi-year contracts.
However, commercial property managers will reject emotional, per-room pricing. They expect proposals structured in Net Cleanable Square Footage (NSF), itemized scope specifications, and proven ISSA production standards.
2. Facility Production Rate Standards
Use these ISSA 612 verified production rates to estimate labor hours during your facility walkthrough:
| Building Category | Cleaning Speed (Sq Ft / Hour) | Nightly Time (10,000 Sq Ft) | Monthly Bid Range (5 Days/Wk) |
|---|---|---|---|
| General Corporate Office | 3,000 – 4,200 sq ft/hr | 2.4 – 3.3 hours | $1,650 – $2,300 / mo |
| Medical & Dental Clinic | 1,500 – 2,200 sq ft/hr | 4.5 – 6.6 hours | $2,800 – $4,200 / mo |
| Daycare & School Facility | 2,000 – 2,800 sq ft/hr | 3.5 – 5.0 hours | $2,200 – $3,200 / mo |
| Industrial Warehouse Office | 4,000 – 5,500 sq ft/hr | 1.8 – 2.5 hours | $1,350 – $1,850 / mo |
| Retail Showroom / Bank | 2,800 – 3,800 sq ft/hr | 2.6 – 3.5 hours | $1,750 – $2,450 / mo |

3. The Commercial Walkthrough Protocol
Never submit a commercial proposal without conducting an on-site facility walkthrough. Inspect these 5 critical areas:
- Restroom Fixture Count: Count total toilets, sinks, urinals, and sanitary dispensers. Restrooms represent 40% of customer complaints.
- Trash Can Density: Note whether desks have individual wastebaskets (adds 20–30 seconds per cubicle) or central waste stations.
- Janitorial Closet Verification: Check for a functional mop sink, hot water access, dedicated electrical outlets for floor buffers, and chemical storage space.
- Flooring Mix Breakdown: Estimate the exact percentage of high-traffic carpet, laminate, and polished vinyl tile (VCT).
- Security & Access Protocol: Confirm whether key fobs, biometric scans, or alarm codes are required for entry.
