Most Seattle offices with steady daily occupancy need washrooms, kitchens and trash handled every day people are in the building, with full vacuuming and dusting two to three times a week. A small office with a handful of staff can often get by on two or three visits a week, while a busy floor in South Lake Union or Downtown usually needs a nightly crew. The right answer depends less on square footage than on how many people use the space, on which days, and how much rain and grit they carry in.
Here is how to build a schedule that matches the way your building is actually used.
Start with headcount, not floor area
Two 10,000 square foot offices can need very different service levels. One might hold 25 people on a quiet engineering floor; the other might host 90 people plus a stream of visitors and a busy kitchen. Cleaning frequency should follow use:
- Under 15 people, mostly desks: two or three visits a week usually covers it, with trash and kitchen touch-ups handled by staff in between.
- 15 to 60 people: most offices land on three to five visits a week, with washrooms and kitchens on every visit.
- 60 or more people, or public-facing space: nightly service, often with a day porter for lobbies, washrooms and meeting rooms during working hours.
Clinics, fitness studios and offices that receive clients all day sit at the top of that range regardless of size.
Hybrid schedules have changed the math
Many Seattle employers, especially in tech, run hybrid schedules where the office fills up Tuesday through Thursday and thins out on Mondays and Fridays. Paying for five identical visits a week in that pattern often means cleaning empty floors twice and running short on the busy days.
A better approach is to weight the schedule toward the days people are actually there. For example, full service on Tuesday, Wednesday and Thursday nights, a lighter visit on Friday night to reset washrooms and kitchens after the week, and nothing on Monday night if the floor was empty all weekend. Ask your contractor to price the schedule by visit type rather than as a flat five-night rate, and review badge or booking data every quarter to see whether the pattern still holds.
Room-by-room frequency guide
These are typical starting points for a general office. Adjust up for heavy use and down for low occupancy.
Every visit (daily in occupied offices)
- Restrooms: clean and disinfect fixtures, restock paper and soap, mop floors.
- Kitchens and break rooms: wipe counters, sinks and appliance fronts, empty trash and compost.
- Trash, recycling and compost collection from desks and common bins.
- Entrances and lobbies: spot vacuum, damp mop hard floors, clean glass doors.
- High-touch points: door handles, elevator buttons, shared equipment.
Two to three times a week
- Full vacuuming of carpeted work areas.
- Dusting of desks (where cleared), sills, partitions and ledges.
- Damp mopping of hard floors outside the entrance zone.
- Meeting rooms: tables, whiteboards and chairs.
Weekly
- Interior glass and partition spot cleaning.
- Detail vacuuming of edges and under furniture.
- Cleaning inside microwaves and wiping out the refrigerator exterior.
Monthly to quarterly
- High dusting of vents, light fixtures and the tops of tall furniture.
- Machine scrubbing or burnishing of resilient and tile floors.
- Upholstery spot cleaning.
Once or twice a year
- Carpet extraction across traffic lanes, with spot extraction in between.
- Strip and refinish of vinyl composition tile, where you have it.
- Exterior and high interior window washing.

The wet season adds work from October to May
Seattle does not deal with road salt the way Chicago or Montréal does, but the long rainy season brings its own load. Wet shoes carry in grit, leaf debris and moisture from fall through spring, and entrances, elevator lobbies and the first stretch of carpet take most of it.
For the wet months, it is worth adding:
- Daily attention to entrance zones, even on days when the rest of the office gets a lighter visit.
- Walk-off matting long enough to cover several steps, swapped or cleaned on a set schedule.
- More frequent damp mopping of hard floors near doors to control slipping and tracked dirt.
- A carpet extraction pass in late spring, once the rain eases, to pull out the grit that settled over the winter.
Damp conditions also matter indoors. Restrooms and kitchens with poor ventilation can develop mildew on grout and caulking faster than in drier climates, so ask that those surfaces be checked and detailed on a regular schedule rather than only when they look bad.
Rules that touch your cleaning plan
Federal OSHA standards require workplaces to keep walking and working surfaces clean and, as far as practical, dry (29 CFR 1910.22), and to keep toilet facilities sanitary (29 CFR 1910.141). Washington enforces workplace safety through the Division of Occupational Safety and Health (DOSH) at the Department of Labor and Industries, under its own state rules. None of these set a fixed number of cleanings per week. They set a standard, and your schedule has to be frequent enough to meet it, which is why entrance zones and washrooms deserve daily attention in a rainy city.
When you hire, confirm that the contractor holds a Seattle business license tax certificate and carries Washington workers' compensation coverage for its crew, and ask for a certificate of liability insurance naming your company or landlord as required by your lease.
Signs your current frequency is wrong
Your schedule is probably too light if you see:
- Washrooms running out of supplies before the next visit.
- Kitchen sinks with dishes and overflowing compost by midafternoon.
- Grey traffic lanes in carpet that come back days after vacuuming.
- Complaints that cluster on the same days of the week.
It may be too heavy if crews report empty bins and untouched floors on certain nights. In that case, move a visit to a busier day instead of simply cutting it.
Frequently asked questions
How often should an office restroom be cleaned?
In an occupied office, restrooms should be cleaned and restocked on every service visit, which means daily for most workplaces. High-traffic restrooms in larger offices or public-facing buildings often need a midday check by a day porter as well. Skipping restrooms is the fastest way to generate complaints, even when the rest of the office looks fine.
Is three times a week enough for a small Seattle office?
For a small office with fewer than about 15 people and no client traffic, three visits a week is often enough, as long as staff empty kitchen trash and wipe up spills in between. During the wet season, ask for entrance mats and floors near the door to be covered on every visit. If complaints build up on the off days, add a short reset visit rather than a full extra clean.
How often should office carpets be deep cleaned?
Most offices schedule hot water extraction once or twice a year across the main traffic lanes, with spot cleaning in between. In Seattle, late spring is a practical time for the main extraction, after the rainiest months have ground grit into the fibres. Entrance carpet and heavy traffic paths may need extraction every quarter.
Should a hybrid office pay for five nights of cleaning?
Not always. If the office is mostly empty on Mondays and Fridays, a schedule built around the busy midweek days, plus a light end-of-week reset, often costs less and keeps the space cleaner when people are there. Review occupancy data every few months and adjust the plan with your contractor.
