Common Area Maintenance (CAM) Fees + Formula

Common Area Maintenance

Understanding Common Area Maintenance (CAM) fees is crucial for both landlords and tenants. CAM fees play a pivotal role in maintaining shared spaces and ensuring the overall well-being of commercial properties.

What are CAM Fees?

Common Area Maintenance (CAM) fees are charges levied by landlords to cover the costs associated with maintaining and operating common areas within a commercial property. These areas typically include lobbies, hallways, parking lots, elevators, landscaping, and other shared spaces. CAM fees ensure that these spaces are well-maintained, creating a positive and functional environment for all tenants.

Some components of CAM fees, include:

1.) Operational Expenses, such as:

   – Routine maintenance and repairs

   – Security services

   – Cleaning and janitorial services

2.) Utilities, such as:

   – Lighting common areas

   – Heating, ventilation, and air conditioning (HVAC)

   – Water and sewer services

3.) Property Management:

   – Management fees

   – Administrative costs

4.) Insurance, such as:

   – Liability insurance for common areas

   – Property insurance

Determining CAM Fees

1.) Lease Agreement: CAM fees are typically outlined in the lease agreement. It’s essential to thoroughly review the lease to understand the specific expenses covered by CAM fees and how they will be calculated.

2.) Base Year Calculation: Many leases use a base year calculation as a reference point for CAM fees. In the base year, the landlord determines the total CAM costs and uses this as a benchmark for future years, with tenants responsible for any increases.

3.) Cap on CAM Fees: Some leases include a cap on annual CAM fee increases to provide tenants with cost predictability. Understanding the cap is crucial for both parties involved.

4.) Audit Rights: Tenants may have the right to audit CAM expenses to ensure transparency and accuracy. This helps maintain trust between landlords and tenants.

Common Area Maintenance (CAM) fees are an integral aspect of commercial real estate, contributing to the upkeep and functionality of shared spaces. By understanding the components of CAM fees, how they are determined, and implementing effective management strategies, both landlords and tenants can build a mutually beneficial relationship that enhances the overall value of the commercial property.


The calculation of Common Area Maintenance (CAM) charges involves several steps, and the formula may vary based on the terms outlined in the lease agreement. Here’s a general formula for calculating CAM charges along with an example:

CAM Charges = (Tenant’s Pro-Rata Share ÷ Total Pro-Rata Share of All Tenants​) × (Total CAM Expenses Base Year CAM Expenses) + Base Year CAM Expenses

Tenant’s Pro-Rata Share: The proportion of the property’s leasable square footage that the tenant occupies.

Total Pro-Rata Share of All Tenants: The sum of the pro-rata shares for all tenants in the property.

Total CAM Expenses: The total expenses incurred for Common Area Maintenance.

Base Year CAM Expenses: The expenses for Common Area Maintenance in the agreed-upon base year.

Example

Let’s say you have a commercial property with a total leasable square footage of 10,000 square feet. Tenant A leases 2,000 square feet, Tenant B leases 3,000 square feet, and Tenant C leases 5,000 square feet.

– Tenant A’s Pro-Rata Share = 2,000 ÷ 10,000 = 0.2

– Tenant B’s Pro-Rata Share = 3,000 ÷ 10,000 = 0.3

– Tenant C’s Pro-Rata Share = 5,000 ÷ 10,000 = 0.5

Now, let’s assume the total CAM expenses for the current year are $50,000, and the base year CAM expenses were $40,000.

CAM Charges for Tenant A = (0.2) × (50,000−40,000) + 40,000

CAM Charges for Tenant A = 0.2 × 10,000 + 40,000

CAM Charges for Tenant A = 2,000 + 40,000 = 42,000

Similarly, you can calculate the CAM charges for Tenants B and C using their respective pro-rata shares.

This formula provides a simplified example, and actual CAM fee calculations may involve additional factors as specified in the lease agreement, such as expense caps, exclusions, or different methods of distribution. Always refer to the terms of the lease agreement for the specific details applicable to your situation.
