What Is CAM For Commercial Real Estate?

What Are CAM Charges?

In the world of commercial real estate investing, the term “CAM charges” stands for the costs a landlord charges tenants for common area maintenance (CAM). These costs can entail just about any detail of managing and maintaining a commercial property, from landscaping to painting to trash services and utilities.

Most of the time, adding CAM charges to a lease is beneficial to the landlord, as it enables them to recuperate certain costs involved with owning and managing the property. This, in turn, gives the commercial property owner a degree of protection from cost increases, protecting the property’s return on investment. Because of these advantages, it has become an industry standard for commercial properties.

Typical Items Covered By CAM Charges

Common area maintenance charges cover a wide array of items that, if neglected, could result in damage to the property that increases the net operational costs. Usually, CAM charges include the various costs of repairing, maintaining, and cleaning the common areas of leased properties that all of the tenants use collectively.

It’s important to note that the itemized costs included in CAM charges are dependent on the type of lease that the tenant and landlord agree upon. These charges can be limited to a few specific aspects of the property or be much broader in scope, covering every expense necessary to keep the property running smoothly and cleanly.

Here are some of the costs generally included in CAM charges:

  • Bathrooms
  • Elevators
  • Hallways
  • Lawncare And Landscaping
  • Parking Lot Maintenance
  • Sidewalks
  • Snow Removal
  • Utilities

Other Operating Expenses Covered By CAM Charges

Other operating expenses could include on-site management staff, security staff, or a number of other costs necessary for the management and maintenance of the commercial property.

Several other operating costs can be included in the common area maintenance charges in a lease, some of which exceed what some people would consider maintenance. These could include:

  • Administrative expenses
  • Building repairs
  • City permits
  • Property insurance
  • Property management fees
  • Property taxes
  • Any other cost a landlord may want to include

Pros And Cons Of CAM Charges

For Tenants


Some tenants may find CAM charges scary because they could end up with cost increases if CAM charges go up in the future. 


Although there’s some risk of costs going up eventually, CAM fees can benefit tenants. When forced to bear every cost of upkeep of common areas, some landlords may put them off instead of handling them expediently. Passing these costs on to tenants generally makes landlords less reluctant to keep up with maintenance, ensuring tenants a clean and well-maintained space.

For Landlords


Adding CAM charges may deter some tenants. Depending on the type of tenants the property manager wants to attract, CAM charges may or may not be a good pricing strategy.


Landlords get protection from fluctuating costs and ensure they always have funding for more extensive maintenance items when it comes time to address them. CAM charges also help ensure commercial real estate investors get more stable net returns. In addition, properties tend to be much better maintained and managed, which benefits the tenants as well.

How Commercial Real Estate Lease Types Impact CAM Charges

What determines how CAM fees are charged to a tenant is the type of lease the commercial property owner offers. The following are the basic terms and CAM charges associated with each type of commercial lease.

Triple Net Lease, Or NNN Lease

Triple net leases require tenants to pay CAM charges and shoulder almost all costs of upkeep. In a NNN lease, tenants pay a pro-rata share of the property taxes, insurance, and common area maintenance costs. Normally, the landlord’s only responsibility with an NNN lease is to pay for capital expenditures like improvements or repairs to the building, land, or parking lot.

While most costs are passed to tenants, in many cases, tenants are only responsible for certain repairs up to a specified dollar amount per year, called a “stop,” which is similar to how an insurance deductible works.

The majority of retail properties come with NNN leases, such as restaurants, strip malls, shopping centers, and single-tenant properties. When it comes to the investors who back commercial real estate, REITs and other investors often prefer to invest in properties with NNN leases because of the stability they bring for net cash flows.

Net Net Lease, Or NN Lease

Net-Net leases only charge tenants their portion of property taxes and insurance, while the commercial landlord covers all common area maintenance costs.

NN leases are less common than NNN leases, but there are advantages for some situations. A NN lease may be attractive to prospective tenants because of their minimized risk of cost increases. Sometimes NN leases are implemented when common area expenses can be shared across multiple properties within an investor’s portfolio. In the few instances you do see these lease structures, they’re typically used in more tertiary, and less sophisticated markets.

Net Lease

Net leases aren’t very common. This type of lease only requires the tenant to pay their share of the property taxes, with the landlord covering all other costs, including property insurance and common area maintenance.

Net leases normally have higher rates because of the costs and risks to the landlord. These leases structures are very uncommon.

Gross Lease

When the landlord covers all costs, including the property taxes, insurance, and common area maintenance costs, it’s called a gross lease. This is a common type of lease encountered by office building tenants.

A gross lease only requires tenants to pay a flat rental rate that doesn’t involve fluctuations in expense recapture from one year to the next. Sometimes with a gross lease, the landlord will even cover the tenant’s utilities in the case of a “Full Service Gross” contract, with some going as far as covering janitorial costs for tenants.

Which Lease Type Is Best For Real Estate Investors?

It’s important to note that property owners typically structure their leases to maximize their return on investment. While passing CAM charges to tenants is usually the most favorable option for the landlord, the operating costs specific to an individual property may actually provide a higher return with a gross, net, or net-net lease in some markets.

Frequently Asked Questions:

How are CAM charges calculated?

CAM charges are usually calculated based on a tenant’s share of the building’s total square footage, as outlined in their lease agreement. The charges cover expenses associated with maintaining and operating common areas, and the amount can be adjusted periodically based on actual expenses.

Are CAM charges included in the rent?

CAM costs are often not included in the regular rent, but instead charged to the renter separately. The CAM fee is often based on a tenant’s proportional part of the building’s total square footage and is used to pay the costs of maintaining and managing common facilities. Typically, this fee is in addition to the tenant’s regular rent and other running costs.

How are CAM charges reviewed and adjusted over time?

Annually, CAM costs are evaluated and modified depending on actual expenditures or as indicated in the lease agreement. They are based on the real costs of maintaining and managing the common areas. An audit may be conducted by a third party to check correctness.Review the lease agreement for specifics.
