Common Area Maintenance (CAM) describes the fees incurred by occupants on top of their base lease that are used to cover regular charges to maintain the shared areas of a given residential or commercial property.

How Does Common Area Maintenance Work?

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

CAM represents "Common Area Maintenance", and refers to the costs paid by occupants to their landlord for the maintenance of a residential or commercial property's typical area.

The value of typical location maintenance (CAM) tends to be greater for commercial property (CRE) residential or commercial properties because there are more occupants and shared areas in such residential or commercial properties.

- Usable Area → The functional location is the area that leased by a specific renter. Therefore, the usable square video footage in a building is what is occupied by a special occupant, inclusive of washrooms, personal conference spaces, and individual workplaces.

  • Common Area → In contrast, the typical location of a building is not rented to an individual however is rather accessible to all occupants for cumulative use. These shared locations can consist of lobbies, parking space, roofing system decks, and elevators.

    So, who pays for the expenses associated with maintaining the common area?

    Since all occupants have the right to use the area, as part of the leasing agreement, each of them contribute towards such payments, typically on a pro rata basis.

    With those profits, the property owner is anticipated by occupants to ensure the common locations are kept arranged and clean, while fixing problems or fixing damages.

    What Does Common Area Maintenance Include?

    The most regular kinds of typical 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).
  • Building Security and Alarm Systems.
  • Concierge Services.
  • Roofing and Landscaping

    For example, if the elevator shared by all occupants were to malfunction, the property manager is accountable for fixing the issue quickly.

    The stipulation referring to common area maintenance (CAM) charges is mentioned in business realty leases, where the specific terms around the legal obligations of each celebration (the lessor and the lessee) are set.

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

    How to Calculate CAM Charges

    The CAM charges matter in real estate, particularly for commercial residential or commercial properties, because the fees affect the overall expense of devoting to a rental arrangement at a given residential or commercial property.

    In a lot of leasing agreements, the tenants pay a portion of the total CAM on a professional rata basis per the negotiated contract, i.e. in percentage with the quantity of square footage rented.

    The calculation of each renter's common location maintenance (CAM) cost, revealed on a yearly basis, can be determined by dividing the tenant's square video footage by the gross leasable area 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 Monthly Fee (Divide by Twelve Months)

    Common Area Maintenance Formula (CAM)

    The typical location maintenance (CAM) sustained by each tenant is determined by multiplying their respective pro-rata share of expenses by the expected 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 quantity must be divided by twelve to transform into a regular monthly cost.

    Conversely, an alternative technique 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 footage.

    Since CAM fees are usually allocated based on the quantity of space inhabited, the tenants with more space rented will incur more CAM charges (and vice versa).

    Common area maintenance is most frequently calculated on an annualized basis, and after that divided into month-to-month payments attributable to each occupant on a per square foot basis.

    Usually at the start of each year, a residential or owner will project the upcoming typical location upkeep (CAM) expenses for the entire residential or commercial property as part of the yearly spending plan, which impacts pricing.

    Broadly put, CAM charges fall under two categories:

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

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

    FAQ: Is Capital Investment Included in CAM?

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

    Why? Capex related the residential or commercial property enhancements, such as developing a more modern gym for tenants, are a kind of discretionary costs (and part of the property manager's cost of ownership).

    However, particular non-discretionary capital expenditures can be categorized as common location upkeep, such as repairing a damaged A/C system, which impacts all existing (and future) tenants.

    CAM Charges Calculation Example

    Suppose a residential or commercial property owner is approximating the typical location maintenance (CAM) charges anticipated on their business office structure for the approaching year, 2024.

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

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

    After dividing the total annual CAM charges by the gross leasable area (GLA), the CAM charge per square foot is $5.20, which represents the quantity that each business renter must contribute based on the quantity of square footage rented each year.

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

    The approximated CAM charge per square footage - $5.20 sq. ft. - must then be assigned in proportion with each renter's pro-rata share.

    The pro-rata share is figured out by dividing the specific tenant's square video footage by the gross leasable location (GLA) of the office building.

    Therefore, if one of the business occupants leased a total of 6k sq. ft., the pro-rata share is 12%.

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