Common Areas vs Tenant Suites: Who Cleans What in an Office Building

In a multi-tenant office building, cleaning splits into two zones: common areas vs tenant suites. The common areas (the lobby, hallways, elevators, stairwells, and shared restrooms) are the landlord’s job, cleaned by the building’s own service. Your suite, the space inside your own door, is usually yours to handle.

Which side of that line your office falls on isn’t set by the cleaning crew you see in the lobby. It’s set by your lease.

The tenants who get caught out are the ones who assumed the service that shines the lobby floor also empties their trash. It doesn’t, unless your lease says so, and one clause settles the whole question.

If you lease office space, here’s exactly who cleans what, and how to tell which parts are on you.

The Two Zones: Common Areas vs Tenant Suites

Every multi-tenant building draws a line between shared space and leased space.

Common areas are the parts everyone uses and nobody leases outright:

  • Building entrances, vestibules, and the main lobby
  • Corridors and hallways between suites
  • Elevator cabs and landings
  • Stairwells
  • Shared restrooms on each floor
  • Common break rooms, mail rooms, and shared conference rooms

Your tenant suite is the space you actually lease, everything inside your entry door:

  • Your offices, cubicle areas, and private conference rooms
  • Your own break room or kitchenette, if it’s inside your suite
  • A private restroom that opens only into your space
  • Your trash, your floors, your desks

The landlord’s building service almost always handles the first list. The second list is where the surprise lives, because whether the building touches it at all comes down to how your lease is written.

If it turns out the suite’s on you, our office cleaning services guide covers how to hire for it, from the scope to the contract.


Who Cleans the Common Areas (and How You Pay for It)

The common areas are the landlord’s responsibility, and the property manager arranges a janitorial service for them. That part is consistent across almost every building.

What’s less obvious is that you’re paying for it. The cost of cleaning the lobby and hallways doesn’t come out of the landlord’s pocket, it’s passed to the tenants as an operating expense, usually under the heading of common area maintenance, or CAM.

In a triple net lease, CAM is a line you pay on top of base rent, and janitorial for the shared spaces is one of the items folded into it. In a full-service lease, the same cost is baked into your single rent number instead of itemized. Either way, the hallway you walk twice a day is being cleaned on your dime. It just shows up differently depending on your lease.

That CAM line affects more than cleaning, because in Pennsylvania it also carries a sales tax wrinkle when cleaning is billed through your lease. Our post on cleaning billed through your lease and the CAM charge question walks through that.


Who Cleans Your Suite

Here’s the part tenants miss. The building service that cleans the common areas usually stops at your door. Whether anyone cleans inside your suite depends entirely on your lease type.

In a full-service (gross) lease, the landlord typically covers a standard nightly clean of your suite along with everything else, so trash, restrooms, and floors inside your space are included. This is common in professional office buildings where the landlord runs cleaning centrally.

In a triple net (NNN) or modified gross lease, suite cleaning is usually not included. CAM pays for the common areas, but your leased space is yours to clean, and if you don’t arrange it, nobody does.

Even in a full-service building, the included clean is a basic one. Anything beyond the standard nightly service, extra frequency, carpet extraction, floor refinishing, or a deep clean, is almost always the tenant’s cost, not the landlord’s.

So the honest answer to “does someone clean my office?” is: check your lease. Assuming it’s covered is exactly how a new tenant ends up three days in with overflowing bins and no one to call.


Your Lease Is the Deciding Document

The clause that settles this is usually called something like “Services” or “Janitorial,” and it sits alongside the operating-expense or CAM definition. Read both. One tells you what the landlord provides, the other tells you what you’re paying for.

Here’s how the common lease types usually shake out:

Lease typeCommon areasYour suite
Full-service (gross)Landlord cleans, cost in your rentUsually included, standard clean
Modified grossLandlord cleans, cost sharedNegotiated, often yours
Triple net (NNN)Landlord cleans, billed as CAMAlmost always yours

Treat this as a starting point, not gospel, because leases are negotiated one at a time and the words in yours win over any general rule. If the janitorial clause names your suite and describes what gets done, you’re covered. If it only mentions common areas, or it’s silent on the inside of your space, that space is yours.

When you’re not sure, ask the property manager one direct question: is cleaning of the leased premises included, or only the common areas? Get the answer in writing before you sign.


If Your Suite Is Yours, Hire a Cleaner

If your lease leaves the suite to you, hiring a cleaner is straightforward, and you’re in control of exactly what gets done.

Start by deciding what your suite actually needs. A ten-person office with one restroom is a different job than a quiet two-room law office. Write down the areas and the tasks so any cleaner you call is pricing the same work. Our guide to writing an office cleaning scope of work walks through exactly that.

The breakdown of what office cleaning includes covers the standard task list you can build your suite scope from.

Then match the frequency to how your space is used, and decide up front which periodic work (carpets, floors, high dusting) you want on the schedule, because those are the tiers inside a cleaning contract that quietly get skipped when nobody names them.

A local cleaner can service your suite on your schedule, independent of whatever the building does in the halls. The two don’t have to match, and yours should fit your actual hours and headcount.


What to Do Next

Pull your lease and find the janitorial clause. If you’re in a full-service building and the clause names your suite, you’re covered for a standard clean, and anything deeper is a conversation with your provider. If you’re on a triple net or modified gross lease, or the clause only mentions common areas, plan to hire your own suite cleaning, because that space is yours no matter what happens in the lobby.

Excellence Janitorial cleans tenant suites across Northeastern Pennsylvania on schedules built around each office, independent of the building’s common-area service.

Frequently Asked Questions

Does my landlord clean my office suite?

It depends on your lease. In a full-service (gross) lease, the landlord usually includes a standard clean of your suite. In a triple net or modified gross lease, the landlord typically cleans only the common areas, and your suite is your responsibility. Check the janitorial or services clause in your lease to be sure.

Who cleans the common areas in an office building?

The landlord or property manager, through a janitorial service they arrange for the shared spaces: lobby, corridors, elevators, stairwells, and shared restrooms. Tenants pay for this indirectly, either as a common area maintenance (CAM) charge in a triple net lease or baked into rent in a full-service lease.

Is janitorial cleaning included in a commercial office lease?

Sometimes. Full-service gross leases often include suite cleaning; triple net leases usually cover only common areas through CAM and leave the suite to the tenant. It varies by lease, so read the specific services clause rather than assuming, and ask the property manager directly if it’s unclear.

What is CAM, and does it cover cleaning?

CAM stands for common area maintenance, the pooled cost of running the building’s shared spaces, which tenants pay as part of their lease. Janitorial cleaning of the common areas is typically one of the items CAM covers. It does not usually cover cleaning inside your leased suite.

Do I have to hire my own cleaner for a leased office?

If your lease leaves your suite to you (common with triple net and modified gross leases), then yes, you arrange and pay for cleaning inside your space. You choose the cleaner, the tasks, and the schedule, independent of the building’s common-area service.

Who cleans the shared restrooms in a multi-tenant building?

Shared restrooms in the common areas are the landlord’s responsibility, cleaned by the building service and funded through CAM or rent. A private restroom that opens only into your suite is part of your leased space, so it usually falls to you unless your lease says otherwise.
