Under-cleaning an office costs more than it saves. Sick days rise, carpets and hard floors wear out years early, client perception drops, and the eventual restoration cleaning costs several times what maintenance would have. Over-cleaning wastes budget on tasks nobody notices. The right answer is a frequency matched to how the space is actually used.
This guide gives a practical framework for setting commercial cleaning frequency, built around headcount, foot traffic and industry requirements, with the task breakdown that belongs in each tier.
The three variables that set your schedule
Start with headcount density: people per square foot, not just total staff. A twenty-person team in 2,000 square feet generates far more soil load than the same twenty people spread across 8,000. Next, foot traffic from outside — every visitor tracks in soil, and entryways receive a disproportionate share of it. Third, industry requirements: medical, dental, food service, childcare and fitness facilities have hygiene obligations that override convenience.
Combine the three and most offices land in one of four tiers: nightly, three times weekly, weekly, or biweekly with daily restroom service. Restrooms and kitchens almost always need a higher frequency than the rest of the floor, and it is normal to split a contract that way.
Frequency by business type
These are the schedules that hold up in practice across Bay Area offices, and they assume standard eight-hour occupancy.
- Medical, dental and clinical: nightly, with disinfection protocols and regulated waste handling
- Restaurants and food service: nightly, plus periodic deep kitchen degreasing
- High-traffic retail: nightly floors and restrooms, weekly detail
- Tech and professional offices, 25+ staff: three to five nights per week
- Small offices, under 15 staff: two to three times weekly, with daily restroom checks if client-facing
- Warehouses and light industrial: weekly detail, daily break room and restroom
- Coworking spaces: nightly, plus daytime porter service during peak hours
What belongs in daily service
Daily tasks are the hygiene and appearance floor — the things that visibly degrade within twenty-four hours. Trash and recycling removal, restroom disinfection and restocking, kitchen and break room surfaces, entryway glass and mats, high-touch point disinfection, and floor vacuuming or dust mopping in traffic lanes.
High-touch points deserve explicit mention in your contract: door handles and push plates, light switches, elevator buttons, shared keyboards and phones, printer and copier panels, refrigerator and microwave handles, conference table surfaces, and stair rails. These are where transmission actually happens, and they are the most commonly skipped items in a cheap contract.
Weekly and monthly rotations
Weekly work covers what daily service intentionally skips: full-floor vacuuming including under desks, mopping all hard floors, dusting workstations and shelving, interior glass and partitions, baseboards, and spot-cleaning of walls and doors.
Monthly and quarterly rotations preserve the asset value of the building itself: high dusting of vents and light fixtures, carpet extraction on traffic lanes, hard floor buffing or recoating, upholstery cleaning on shared seating, window cleaning, and deep degreasing of kitchen equipment. Skipping this tier is the most expensive false economy in facilities management — carpet that is extracted quarterly lasts roughly twice as long as carpet that is only vacuumed.
- Weekly: full vacuum, mop, dust, interior glass, baseboards
- Monthly: high dusting, vents, upholstery, detail edges
- Quarterly: carpet extraction, floor refinishing, window cleaning
Day porter versus night crew
Night cleaning is the default because it does not disturb work and lets crews move freely. But buildings with heavy daytime traffic — lobbies, coworking, clinics, showrooms — often need a day porter as well: someone present during business hours to keep restrooms stocked, handle spills immediately, reset conference rooms between meetings and maintain entryway appearance.
The hybrid model is the most cost-effective for client-facing spaces. A part-time porter during peak hours plus a lighter night crew usually outperforms a heavier night-only contract, because appearance problems are solved when they occur rather than twelve hours later.
Measuring whether your contract is working
Vague contracts create vague results. Ask for a written scope broken down by daily, weekly, monthly and quarterly tasks, a defined inspection schedule, and a named account manager. Monthly walkthroughs with a scored checklist catch drift before it becomes a complaint.
Track the practical signals too: restroom supply-out incidents, employee complaints, entryway appearance at 9 a.m., and carpet condition in traffic lanes over time. If those four are healthy, your frequency is right. If restrooms run out or the lobby looks tired by mid-week, the schedule needs adjusting before the contract does.
Budgeting realistically
Commercial cleaning in the Bay Area typically runs $0.10 to $0.22 per square foot per visit for standard office work, with medical and food service higher. A 5,000 square foot office cleaned three nights a week generally budgets $1,800 to $3,200 monthly depending on scope and restroom count.
Rather than cutting frequency when budgets tighten, cut the right tasks. Reducing full-floor vacuuming from daily to three times weekly while keeping restrooms, kitchens and high-touch disinfection daily preserves both hygiene and appearance at a meaningfully lower cost.
Getting the schedule right from day one
A proper commercial quote starts with a walkthrough: square footage, floor types, restroom fixture count, kitchen setup, headcount, visitor volume, security and access requirements, and any compliance obligations. Anyone quoting a per-square-foot number without seeing the space is guessing, and that guess becomes your service problem later.

Frequently asked
Quick answers
How often should office restrooms be cleaned?
Daily at minimum for any staffed office, and multiple times daily for high-traffic or client-facing buildings. Restroom frequency should usually exceed general floor frequency.
Is night cleaning better than day cleaning?
Night cleaning suits most offices because crews work uninterrupted. Client-facing and high-traffic spaces do better with a hybrid: a day porter for upkeep plus a night crew for full service.
What does commercial cleaning cost per square foot?
Typically $0.10 to $0.22 per square foot per visit for standard offices in the Bay Area, with medical, dental and food service at the higher end.
