What is Common Area Maintenance?

Common Area Maintenance (CAM) refers to the costs incurred by occupants on top of their base rent that are used to cover regular charges to maintain the shared spaces of an offered residential or commercial property.

How Does Common Area Maintenance Work?

Common area maintenance (CAM) charges are separate costs incurred per month on top of the base rent to cover costs connected to residential or commercial property upkeep.

CAM represents "Common Area Maintenance", and describes the charges paid by occupants to their proprietor for the upkeep of a residential or commercial property's common location.

The significance of common location upkeep (CAM) tends to be greater for business real estate (CRE) residential or commercial properties because there are more renters and shared spaces in such residential or commercial properties.

- Usable Area → The functional location is the space that rented by a particular renter. Therefore, the functional square video in a building is what is occupied by an unique tenant, inclusive of restrooms, personal meeting spaces, and private workplaces.

  • Common Area → On the other hand, the common area of a building is not leased to an individual but is rather accessible to all tenants for collective usage. These shared locations can include lobbies, parking space, roof decks, and elevators.

    So, who pays for the costs related to keeping the typical area?

    Since all renters deserve to use the space, as part of the leasing contract, each of them contribute towards such payments, typically on a professional rata basis.

    With those proceeds, the landlord is anticipated by tenants to guarantee the common locations are kept organized and tidy, while fixing issues or repairing damages.

    What Does Common Area Maintenance Include?

    The most regular kinds of common areas at residential or commercial properties consist of the copying:

    - Lobby and Hallway.
  • Open Area Workspace. - Fitness Center (Public Gym).
  • Janitorial Services. - Elevators.
  • Parking Spaces.
  • Shared Amenities.
  • Surrounding Outdoor Areas (Pool).
  • Building Security and Alarm Systems.
  • Concierge Services.
  • Roofing and Landscaping

    For example, if the elevator shared by all tenants were to malfunction, the proprietor is accountable for fixing the issue promptly.

    The clause referring to common area maintenance (CAM) charges is mentioned in commercial property leases, where the specific terms around the legal obligations of each party (the lessor and the lessee) are set.

    Furthermore, the type of lease signed between the 2 celebrations is key to determining each celebration's respective responsibilities, e.g. triple web (NNN).

    How to Calculate CAM Charges

    The CAM charges matter in genuine estate, especially for business residential or commercial properties, because the costs affect the overall expense of committing to a rental arrangement at a given residential or commercial property.

    In most leasing arrangements, the renters pay a part of the overall CAM on a pro rata basis per the worked out arrangement, i.e. in proportion with the quantity of square footage leased.

    The estimation of each occupant's common area upkeep (CAM) fee, revealed on an annual basis, can be determined by dividing the renter's square footage by the gross leasable area in the structure.

    - Step 1 → Divide the Tenant's Rentable Square Footage (RSF) by the Gross Leasable Area (GLA) of the Residential or commercial property.
  • Step 2 → Multiply the Pro-Rata Share (%) by the Estimated Annual CAM Charges of the Residential or commercial property.
  • Step 3 → Convert the Annual CAM Charge of a Tenant into a Month-to-month Fee (Divide by Twelve Months)

    Common Area Maintenance Formula (CAM)

    The typical location upkeep (CAM) incurred by each occupant is determined by increasing their respective pro-rata share of costs by the anticipated annual CAM charge.

    Where:

    - Pro-Rata Share (%) = Tenant Rentable Square Footage (RTF) ÷ Gross Leasable Area (GLA).
  • Annual CAM Charge = Σ Monthly CAM Fees × 12 Months

    Since the tenant CAM charge is an annualized metric, the quantity must be divided by twelve to transform into a monthly charge.

    Conversely, an alternative method to calculate the CAM charges is on a per square foot (sq. ft.) basis, which is done by dividing the estimated yearly CAM fees by the residential or commercial property's leasable square footage.

    Since CAM costs are usually assigned based on the amount of area occupied, the occupants with more space leased will sustain more CAM charges (and vice versa).

    Common location upkeep is most typically computed on an annualized basis, and then divided into month-to-month payments attributable to each tenant on a per square foot basis.

    Usually at the start of each year, a residential or commercial property owner will predict the upcoming common area upkeep (CAM) costs for the whole residential or commercial property as part of the yearly budget, which affects rates.

    Broadly put, CAM charges fall under two categories:

    1. Controllable Charges → The residential or commercial property owner has direct impact over manageable charges (e.g. administrative costs, personnel payroll).
  1. Uncontrollable Charges → On the other hand, charges, stay outside the residential or commercial property owner's control and are unpredictable (e.g. snow storm, fire).

    However, CAM cost price caps and floorings can set restrictions on how much lease can be changed.

    FAQ: Is Capital Investment Included in CAM?

    For the a lot of part, capital investment (Capex) are left out from typical location upkeep (CAM), depending on the context of the invest.

    Why? Capex related the residential or commercial property improvements, such as developing a more modern-day fitness center for tenants, are a form of discretionary spending (and part of the property manager's cost of ownership).

    However, specific non-discretionary capital investment can be classified as common location upkeep, such as fixing a damaged A/C system, which impacts all existing (and future) tenants.

    CAM Charges Calculation Example

    Suppose a residential or commercial property owner is estimating the common area maintenance (CAM) charges anticipated on their business office complex for the upcoming year, 2024.

    The total annual CAM charges for the entire office structure are predicted to be $260k, while the gross leasable area (GLA) is 50k sq. ft.

    - Annual CAM Charge = $260,000.
  • Gross Leasable Area (GLA) = 50,000 sq. ft.

    After dividing the overall annual CAM charges by the gross leasable location (GLA), the CAM charge per square foot is $5.20, which represents the amount that each industrial tenant need to contribute based upon the amount of square video footage rented each year.

    - CAM Charge per Square Footage = $260,000 ÷ 50,000 sq. ft. = $5.20

    The estimated CAM charge per square footage - $5.20 sq. ft. - should then be designated in percentage with each occupant's pro-rata share.

    The pro-rata share is identified by dividing the individual renter's square footage by the gross leasable location (GLA) of the office complex.

    Therefore, if among the commercial renters leased an overall of 6k sq. ft., the pro-rata share is 12%.
