Short answer: most Chicago businesses pay $200 to $800 per month for janitorial service on a light schedule, and buildings over 20,000 square feet commonly pay more than $1,200 per month. Nightly five-night contracts for a 10,000 square foot office usually land in the low to mid thousands per month. The real number depends on square footage, frequency, restroom count and any medical areas, and it comes from a walkthrough, not a guess.
If you manage an office, a medical suite or a multi-tenant building, janitorial service is probably one of your largest recurring facility costs. This guide explains how janitorial services in Chicago are priced in 2026, shows monthly examples by building size, and walks through the contract terms that change what you actually pay over a year.
Janitorial pricing in Chicago is quoted three ways: per square foot, per cleaner hour, or as a flat monthly rate. Most proposals end with a monthly number, but the math underneath is one of the first two.
Prices in 2026 are running roughly 8 to 12% above 2024 levels. If you are renewing a contract signed two years ago, expect the new number to reflect that.
For a deeper look at the per square foot and hourly ranges, see our 2026 Chicago office cleaning cost guide.
Frequency is the biggest single lever on your monthly cost. A nightly program costs more per month than a weekly one, but it usually costs less per visit.
When a crew cleans every night, the space never gets very dirty. Trash is light, restrooms need a reset rather than a scrub, and floors need a pass instead of a recovery. The crew moves fast and the per visit rate drops well below the light schedule range. When a crew comes once a week, each visit has to undo seven days of use, so each visit takes longer and costs more per square foot.
A month has about 21.7 weekdays, so a five night contract means roughly 21.7 visits per month. A two night schedule is about 8.7 visits and a weekly schedule is about 4.3 visits. Those multipliers are the backbone of every monthly quote.
The examples below show how a typical Chicago quote is built from labor hours. They assume a standard office with carpet and some hard floor, normal traffic, and supplies like liners and restroom paper billed separately. They are planning ranges, not quotes. Your building will be priced from a walkthrough.
A small office with one or two restrooms and a kitchenette usually needs one cleaner for about 1 to 1.5 hours per visit.
A midsize office with open seating, private offices, two to four restrooms and a break room usually needs about 3 cleaner hours per night.
A full floor or small building with multiple restroom cores, conference rooms and a lobby usually needs a crew of two or three for a combined 6 to 8 hours per night.
A multi-tenant building or large single user office needs a supervised crew. Larger buildings get some efficiency, so the blended hourly rate often comes down.
Notice that the per visit cost on a nightly contract works out well below the light schedule per square foot range. That is normal. The per square foot range describes lighter schedules where each visit is a fuller clean. Nightly contracts are priced on the labor hours your building actually needs.

Two buildings with the same square footage can get very different numbers. These are the factors that move the quote, roughly in order of impact.
More visits mean more monthly cost and a lower cost per visit. Matching frequency to real traffic is the fastest way to right size a contract.
Open floor plans clean faster per foot than a maze of private offices.
Restrooms are the most labor intensive rooms in any building. Each additional restroom core adds cleaning, disinfecting and restocking time every visit. Public or shared restrooms in multi-tenant buildings add more.
Exam rooms, procedure rooms and lab spaces need healthcare specific protocols, documented disinfection and careful handling of waste streams. That takes more time and training. Our medical office cleaning service is scoped separately for that reason.
Most Chicago janitorial work already happens after hours, so standard nightly service is priced with that in mind. Very late starts, weekend only visits and buildings with restricted access or security escorts in the Loop can add a modest premium.
Hard floors need more frequent mopping and periodic scrubbing. Chicago winters bring ice melt and salt residue into every entrance, which adds entry floor care from roughly November through March.
If restrooms and lobbies need attention during business hours, a day porter adds hours on top of the nightly crew. See our guide to day porter services in Chicago for when that makes sense.
The monthly number is only part of the cost. The contract terms decide how flexible that number is and how it changes over time.
Many janitorial contracts run 12 months, sometimes longer. A 30-day out clause lets either side end the agreement with 30 days written notice. It protects you if service slips. A vendor confident in its work should not resist a reasonable out clause. Be cautious with long terms that have no exit and auto renew quietly.
Multi-year contracts often include an annual price increase, commonly tied to a fixed percentage or to wage changes. Ask what the escalator is, when it applies and whether it is capped. A low starting price with an uncapped escalator can cost more over three years than a fair starting price with a fixed one.
Some quotes include consumables like trash liners, toilet paper, paper towels and hand soap. Others bill them separately at cost or with a markup. Cleaning chemicals and equipment are almost always included.
Carpet extraction, floor stripping and refinishing, window washing and high dusting are usually priced as separate line items. Ask for them to be listed with a frequency so your annual budget is complete.
Your vendor should carry general liability, workers compensation and a janitorial bond, and should provide a certificate of insurance naming your property manager or landlord when required. Many Chicago buildings will not let a crew in without one.
The lowest bid is not the cheapest contract. Bids that come in far below the market usually reflect fewer labor hours on site, skipped tasks, or a crew that changes every month. Here is how to compare apples to apples.

Small and midsize Chicago offices on a light schedule typically pay $200 to $800 per month. Buildings of 20,000 square feet and up commonly pay more than $1,200 per month, and nightly five night programs for larger buildings run higher. Your exact price depends on square footage, frequency, restrooms and any medical areas.
Both methods are common. Light schedules are often quoted at about $0.07 to $0.25 per square foot per visit. Nightly contracts are usually built from labor hours at about $35 to $75 per cleaner hour. Most vendors convert either method into a flat monthly price so your budget stays predictable.
Commercial cleaning prices in 2026 are running roughly 8 to 12% above 2024 levels. Higher wages for cleaning staff are the main cause, along with rising costs for supplies and insurance. If your contract was priced two or more years ago, expect a renewal to reflect those increases.
Either approach can work, as long as it is clear. Some vendors include liners, paper products and soap in the monthly price, while others bill them separately. Ask every bidder to show supplies on their own line so you can compare quotes fairly and track usage over time.
A good contract lists the cleaning scope by area and frequency, the monthly price, how supplies are handled, any annual escalator, the term length and a 30-day out clause. It should also confirm insurance coverage and name a point of contact. Periodic services should appear as separate line items with their own schedule.
