How Much Do Office Cleaning Services Cost in the San Francisco Bay Area?

How Much Do Office Cleaning Services Cost in the San Francisco Bay Area?Commercial office cleaning in the San Francisco Bay Area typically runs $0.10 to $0.25 per square foot per month for recurring janitorial service, or $45 to $75 per hour per cleaner. A 5,000 sq ft office cleaned three nights a week generally falls between $800 and $1,300 per month. Bay Area rates sit above national averages because California labor costs are higher — San Francisco's minimum wage alone is $19.61 per hour as of July 2026.

Most cleaning companies won't publish numbers. We will, because a range you can budget against is more useful than a quote form.

Recurring office cleaning rates by building size

Smaller buildings pay more per square foot. Setup time, travel, and labor minimums don't shrink proportionally, so a 3,000 sq ft suite costs more per foot than a 40,000 sq ft floor plate.

Building size 5 nights/week 3 nights/week 1x/week

Under 5,000 sq ft $0.22–$0.35 $0.16–$0.26 $0.08–$0.14

5,000–20,000 sq ft $0.16–$0.26 $0.11–$0.18 $0.06–$0.10

20,000–50,000 sq ft. $0.13–$0.20 $0.09–$0.15 $0.05–$0.08

Over 50,000 sq ft $0.11–$0.17 $0.08–$0.13 —

Per square foot, per month, of cleanable square footage. Medical, dental, lab, and food service spaces run $0.20–$0.35 per sq ft due to added sanitation requirements.

per sq ft

Most Bay Area commercial cleaning companies carry a monthly minimum in the $600–$1,000 range. Below that, the overhead of servicing an account exceeds what the work bills.

What drives the price

Frequency. Nightly costs more per month than three-nights-a-week, but less per visit — soil load compounds when you skip days. Weekly-only service on a busy office often costs more over time, because the building degrades past what routine cleaning can restore.

Restroom count and traffic. Restrooms are the most labor-intensive square footage in any building. Two restrooms in a 5,000 sq ft office prices very differently than six.

Floor type. Carpet needs vacuuming and periodic extraction. VCT needs stripping and refinishing on a cycle. Polished concrete, stone, and hardwood each have their own requirements and costs.

Access and hours. After-hours work with keys and alarm codes is standard. Restricted windows, badge-in requirements, escorted access, or daytime-only cleaning all add labor.

Specialty requirements. Medical and lab spaces, food prep areas, enhanced disinfection protocols, and certified green product requirements each carry a premium.

A worked example

A 5,000 sq ft professional office in SoMa — open plan, two restrooms, a break room, mostly carpet with tile in wet areas, cleaned three nights a week:

Trash and recycling removal at all stations

Vacuum all carpet, damp mop hard floors

Restrooms: fixtures cleaned and disinfected, floors mopped, supplies restocked

Break room: counters, sink, tables, appliance exteriors

High-touch disinfection: door handles, light switches, shared surfaces

Entry glass and doors spot cleaned

Typical range: $800–$1,300 per month.

Quarterly carpet extraction on that space would add roughly $250–$500 per visit. Annual floor refinishing in the tile areas is quoted separately.

Why the cheapest bid usually costs more

This is arithmetic, not sales talk. Run it on any bid you receive.

San Francisco's minimum wage is $19.61 per hour. Nobody retains reliable janitorial staff at exactly minimum, so realistic base pay runs $22–$26. On top of that an employer carries payroll taxes, workers' compensation (janitorial carries one of the higher comp rates in California), general liability, mandated paid sick leave, uniforms, equipment, and supplies. Fully loaded, a legally employed Bay Area cleaner costs an employer roughly $32–$40 per hour before a dollar of supervision, overhead, or profit.

That's why billable rates start around $45. A bid that implies $30 per hour of billable labor cannot pay a properly employed, insured worker. It's being covered one of three ways: fewer hours than the scope requires, workers paid off the books, or a company that will fail the account within a year.

How to check a bid: divide the monthly price by $45. That's roughly the maximum labor hours the vendor can afford to put in your building. Compare it against what your building plausibly needs. Commercial cleaning production rates run around 3,000–3,500 sq ft per hour for standard office work — so a 20,000 sq ft office needs roughly 6 hours per visit.

Is there a minimum job size?

Market standard in the Bay Area is $600–$10,000 per month for recurring commercial services.

Getting an accurate number for your building

A real proposal requires a walkthrough. What matters: cleanable square footage (not gross), restroom fixture count, floor surface breakdown, occupancy and traffic patterns, access constraints, and specialty requirements.

Expect a written scope of work listing every task and its frequency — not a single line item with a price.

Common questions

Is it cheaper to hire an in-house janitor? Rarely, once you account for payroll taxes, workers' compensation, benefits, paid leave, equipment, supplies, coverage for absences, and management time. A contracted vendor absorbs all of that, plus carries the liability.

Should I pay per square foot, hourly, or a flat monthly fee? Flat monthly against a written scope is the most common and the most predictable. Hourly suits project work. Per square foot is a way of arriving at the monthly number, not usually the billing method.

How often do rates increase? Annual increases of 3–5% are standard and typically track labor costs. San Francisco's minimum wage adjusts every July 1 with CPI, so an increase in the second half of the year is normal. Any escalation clause should be capped.

Why is my quote higher than the national average? Bay Area labor costs. National figures often reflect markets with minimum wages under $10. Compare against regional numbers, not national ones.
