What is common area maintenance?

Common area maintenance (CAM) is the upkeep and cleaning of the shared spaces in a building or complex that every tenant uses but no one rents individually, such as lobbies, hallways, elevators, restrooms, parking areas, and shared air systems. In commercial leases, the cost is typically passed to tenants as a CAM charge based on their share of the property.

What does common area maintenance usually include?

It commonly includes janitorial and floor cleaning, carpet and hard-surface care, restroom servicing, snow and ice removal, landscaping, lighting and minor repairs, and upkeep of shared HVAC and air systems. The exact list depends on the property and the lease, since there is no single universal definition of CAM.

Who pays for common area maintenance?

In most commercial and retail leases, tenants reimburse the landlord for common area maintenance through a CAM charge, usually their pro-rata share of the building. In apartment communities and associations, the cost is built into operating budgets, HOA dues, or rent rather than billed as a separate line item.

How can a property manager control common area maintenance costs?

The biggest lever is moving from reactive, one-off cleanings to a right-sized recurring schedule, and consolidating trades like carpet, hard floors, and air systems under one vendor instead of three. That reduces duplicate trip charges, keeps spaces consistently presentable, and makes the annual budget predictable.

Common area maintenance, often shortened to CAM, is the ongoing upkeep and cleaning of the shared spaces in a building or property that every tenant uses but no single tenant rents. Think lobbies, hallways, elevators, shared restrooms, parking areas, and the air systems that serve those spaces. Here is what it actually covers, what moves the cost, and how to keep it manageable.

The short definition

A common area is any space used by or for the benefit of all occupants rather than leased to one of them. According to commercial real estate guidance, that typically includes hallways, lobbies, elevators, parking lots, public restrooms, and shared building space. Common area maintenance is simply the work of keeping all of that clean, safe, and presentable.

In most commercial and retail leases, that cost is passed to tenants as a CAM charge, usually their pro-rata share of the property. In apartment communities and associations, the same work is funded through operating budgets, HOA dues, or rent instead of a separate billed line. Either way, someone is paying to keep the shared spaces in good shape, and the quality of that work shows the moment anyone walks in the door.

What common area maintenance typically includes

There is no single, universal list. Industry resources are clear that CAM can vary from one market to another and even from one landlord to the next, because what counts is whatever the lease defines. That said, the maintenance and cleaning side of CAM usually covers:

Janitorial and floor cleaning of lobbies, corridors, and shared rooms
Carpet care in hallways, entries, and amenity spaces
Hard-surface and tile and grout cleaning for shared floors
Restroom cleaning and restocking in public and shared facilities
Snow and ice removal and entryway mat service, which matters a lot in Minnesota
Landscaping and grounds upkeep
Lighting, signage, and minor repairs in common areas
Shared HVAC and air system cleaning, including ducts and dryer vents in multi-unit laundry rooms

CAM charges can also fold in non-cleaning costs like property insurance, management fees, and administrative overhead, depending on the lease. The hands-on maintenance work above is the part that keeps a property looking and feeling cared for.

What drives the cost

Two identical-looking buildings can have very different CAM costs. The usual factors:

Traffic and size. More units and more foot traffic mean shared floors, entries, and restrooms wear faster and need more frequent service.

Seasonality. In the East Metro, winter is the expensive season for common areas. Road salt, grit, and slush get tracked across lobby floors and hallway carpet for months, which is why many managers tighten the cleaning schedule from late fall through spring.

Number of vendors. Juggling separate companies for carpet, hard floors, and air systems means duplicate trip charges, three schedules, and three invoices to reconcile.

Reactive versus planned work. Cleaning only when a space already looks bad almost always costs more than a steady schedule, because neglected areas need an expensive deep reset to recover.

How to keep it under control

The two highest-leverage moves are simple. First, replace reactive cleanings with a right-sized recurring schedule so spaces stay consistently presentable for a predictable cost. Second, consolidate the trades. When one local crew handles carpet, hard surfaces, and air systems, the work can be routed and priced together, which trims duplicate costs and gives you a single point of contact.

That consolidation is the entire idea behind AB CAM Services. We handle the cleaning and maintenance side of common areas, carpet, hard floors, tile and grout, and air systems, for apartment communities, associations, and commercial properties across the Twin Cities East Metro, on a schedule you set once.

The bottom line

Common area maintenance is everything that keeps shared spaces clean, safe, and inviting, from hallway carpet to snow removal to the air systems behind the walls. The exact scope is defined by your lease or budget, but the path to controlling it is the same: plan the work on a schedule and put as much of it as possible under one reliable vendor.
