What is Common Area Maintenance?

Common Area Maintenance (CAM) describes the fees incurred by renters on top of their base rent that are used to cover regular charges to preserve the shared spaces of a given residential or commercial property.

How Does Common Area Maintenance Work?

Common location maintenance (CAM) charges are separate fees incurred monthly on top of the base lease to cover costs connected to residential or commercial property maintenance.

CAM stands for "Common Area Maintenance", and refers to the fees paid by renters to their landlord for the maintenance of a residential or commercial property's typical location.

The value of common location upkeep (CAM) tends to be greater for industrial property (CRE) residential or commercial properties since there are more renters and shared spaces in such residential or commercial properties.

- Usable Area → The usable location is the space that leased by a specific tenant. Therefore, the usable square video footage in a structure is what is occupied by a distinct occupant, inclusive of toilets, private meeting rooms, and individual workplaces.

  • Common Area → In contrast, the typical location of a structure is not leased to a specific however is rather available to all occupants for cumulative use. These shared locations can consist of lobbies, parking space, roofing decks, and elevators.

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

    Since all tenants have the right to utilize the space, as part of the leasing agreement, each of them contribute towards such payments, normally on a professional rata basis.

    With those profits, the proprietor is anticipated by occupants to ensure the typical areas are kept organized and tidy, while repairing issues or fixing damages.

    What Does Common Area Maintenance Include?

    The most regular types of common locations at residential or commercial properties include the copying:

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

    For circumstances, if the elevator shared by all renters were to malfunction, the property owner is responsible for repairing the problem immediately.

    The stipulation pertaining to common area upkeep (CAM) charges is stated in commercial property leases, where the particular terms around the legal obligations of each party (the lessor and the lessee) are set.

    Furthermore, the type of lease signed between the two parties is crucial to figuring out each celebration's particular obligations, e.g. triple web (NNN).

    How to Calculate CAM Charges

    The CAM charges matter in real estate, specifically for commercial residential or commercial properties, because the charges affect the total cost of devoting to a rental arrangement at a provided residential or commercial property.

    In the majority of leasing contracts, the renters pay a part of the overall CAM on a professional rata basis per the worked out arrangement, i.e. in proportion with the quantity of square video rented.

    The estimation of each tenant's common location maintenance (CAM) cost, revealed on a yearly basis, can be determined by dividing the occupant's square footage by the gross leasable location in the building.

    - 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 Renter into a Month-to-month Fee (Divide by Twelve Months)

    Common Area Maintenance Formula (CAM)

    The typical area maintenance (CAM) incurred by each renter is determined by increasing their particular pro-rata share of expenses 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 occupant CAM charge is an annualized metric, the amount should be divided by twelve to convert into a month-to-month fee.

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

    Since CAM costs are frequently assigned based on the amount of area occupied, the renters with more area rented will sustain more CAM charges (and vice versa).

    Common area maintenance is most typically computed on an annualized basis, and then divided into regular monthly payments attributable to each renter on a per square foot basis.

    Usually at the start of each year, a residential or commercial property owner will project the upcoming common area maintenance (CAM) costs for the entire residential or commercial property as part of the yearly spending plan, which impacts prices.

    Broadly put, CAM charges fall under 2 categories:

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

    However, CAM fee cost caps and floors can set restraints on just how much lease can be changed.

    FAQ: Is Capital Expenditure Included in CAM?

    For the a lot of part, capital expenditures (Capex) are omitted from common area maintenance (CAM), based on the context of the invest.

    Why? Capex related the residential or commercial property improvements, such as constructing a more modern fitness center for renters, are a kind of discretionary spending (and part of the landlord's expense of ownership).

    However, specific non-discretionary capital expenditures can be classified as common area upkeep, such as repairing a broken A/C system, which impacts all existing (and future) occupants.

    CAM Charges Calculation Example

    Suppose a residential or commercial property owner is approximating the common location maintenance (CAM) charges expected on their industrial office complex for the upcoming year, 2024.

    The total annual CAM charges for the whole office complex are projected 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 area (GLA), the CAM charge per square foot is $5.20, which represents the amount that each commercial occupant need to contribute based on the amount of square video leased each year.

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

    The estimated CAM charge per square video footage - $5.20 sq. ft. - need to then be assigned in percentage with each renter's pro-rata share.

    The pro-rata share is identified by dividing the individual tenant's square video footage by the gross leasable location (GLA) of the workplace building.

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

    - Pro-Rata Share (%) = 6,000 sq. ft. ÷ 50,000 sq.
