What Fremont buildings pay for cleaning, service by service
Cleaning in the Tri-City area is priced in a handful of units, and each service carries its own band. Here are the current figures for every service on this site, three sample buildings worked through, and a method for reading two quotes side by side.
Four units that cleaning is priced in
Recurring janitorial and office cleaning is quoted as a rate on each square foot of cleanable space, billed monthly. Daytime porters bill by the hour the porter is on site. Carpet extraction is priced per square foot each time the carpet is cleaned, and post-construction cleaning is a one-time square-foot price that covers the rough, progress and final stages together.
Hard-floor finish work runs per square foot with a minimum charge, so a small lobby floor still carries a full job price. Concrete scrubbing on plant and warehouse floors is quoted from the floor itself: its area, coating, soil load and the shutdown window that frees it up.
Know the unit before comparing anything. A monthly square-foot rate and an hourly porter rate measure different work, and a building that uses both pays for each on its own line.
The current bands, Newark to Milpitas
The figures below are current as of 2026 and span the service area, with Newark at the low end and Milpitas at the top. They draw on recent public-agency cleaning bids checked against independent rate surveys, and they are planning numbers, not a quote.
Recurring janitorial cleaning five nights a week lands between $0.16 and $0.25 per square foot monthly for most buildings, starting near $0.10 for a light suite and reaching $0.45 for dense, detailed accounts. Plant and warehouse support space prices lower per foot because so much of the floor is open: $0.09 to $0.21 for most sites, with a spread from $0.06 to $0.37.
Project and periodic work has its own spread. Porters bill $31 to $56 an hour at the extremes, carpet extraction runs from $0.12 to $0.68 a foot per cleaning, finish work on hard floors spans $0.36 to $3.00, and post-construction cleaning spans $0.23 to $1.00 for the whole project.
Medical suites, labs and cleanrooms run 20 to 50 percent above the office band, because clinical rooms and controlled areas follow the facility’s own products and sequence. Data center white space also prices above office work, shaped by the site controls each visit follows.
Three Tri-City buildings, worked through
A 7,500-square-foot Union City office with one restroom core and a kitchen, cleaned five nights at $0.18, comes to $1,350 a month. The rate sits low in the band because the floor plan is open and the restrooms are few.
A 40,000-square-foot distribution building on the I-880 corridor needs its locker rooms, break areas, restrooms and dock office cleaned five nights through industrial cleaning. At $0.12 across the building, the bill is $4,800 monthly as of 2026, with concrete scrubbing quoted on its own for the shutdown weekends.
A Newark retail center that adds a day porter for four hours each weekday logs 88 porter-hours in a 22-weekday month. At $38 an hour, that daytime coverage costs $3,344, on top of the nightly janitorial visit that handles the full routine.
What moves a Fremont rate
Frequency moves the monthly total more than anything else. Five nights costs more than three, but the per-visit price falls as visits rise, because setup and travel spread over more work. Room mix comes next: restrooms, kitchens and breakrooms take the most minutes per foot, and open workstations take the fewest.
Access adds time. Badge escorts, gowning before each controlled room, alarm steps and rooms that open only at set hours all lengthen a visit. Early-morning and weekend windows price above a standard evening, and small buildings pay more per foot than large ones.
Labor cost sets the floor under every rate. The 2026 minimum wage is $18.05 in Fremont, $18.50 in Milpitas and $17.79 for larger Hayward employers, while Newark and Union City follow the state’s $16.90. Fremont prices sit about 5 percent above the base the bands are built on, Milpitas about 7 percent, and Newark and Union City about 4 percent, all as of 2026.
Reading two quotes side by side
Two quotes are only comparable when they price the same building the same way. Check that each one uses the same cleanable square footage, the same rooms, the same nights and the same service window; a clear scope of work makes that check quick. A bid that assumes three nights against another that assumes five is a smaller job, not a better price.
Look at what sits outside the monthly rate. Liners, paper and soap belong on one bid’s line or the other’s, and periodic carpet, floor and window work should appear as separate prices with their own calendar. Porter hours deserve their own line as well.
The number that counts comes from the building. Every quote here includes an on-site walkthrough that sets the rooms, tasks, frequency and windows, and the quote is built from that list rather than from a band on a page. Start one through janitorial services and bring your current task list along. To weigh the companies themselves, use our guide to choosing a cleaning company.
A few useful answers
Quick answers.
Why does a small Tri-City suite carry a higher rate per foot than a big floor?
Setup, travel and restroom time stay roughly fixed whatever the size, so a small suite spreads them over fewer feet. A large open floor spreads the same costs thin and lands lower in the band.
What sets the price of scrubbing a Fremont plant's concrete floor?
From the floor: its area, coating, soil load and the shutdown or off-hours window available. The walkthrough measures those, and the quote follows them.
How far above office pricing do labs and medical suites run?
As of 2026, labs and medical suites run 20 to 50 percent above the office band. Offices and corridors in the same building stay near the office rate.
Where between Newark and Milpitas does cleaning price highest?
Milpitas sits at the top of the range, with Newark and Union City at the bottom, following their local wage floors. Fremont and Hayward fall between them.
