What prevails Area Maintenance?
Common Area Maintenance (CAM) refers to the fees incurred by occupants on top of their base rent that are used to cover regular charges to preserve the shared areas of an offered residential or commercial property.

How Does Common Area Maintenance Work?
Common area maintenance (CAM) charges are separate fees incurred each month on top of the base rent to cover costs connected to residential or commercial property maintenance.

CAM represents "Common Area Maintenance", and describes the costs paid by renters to their property owner for the upkeep of a residential or commercial property's common area.
The significance of common area upkeep (CAM) tends to be greater for business genuine estate (CRE) residential or commercial properties considering that there are more tenants and shared areas in such residential or commercial properties.
- Usable Area → The usable area is the space that leased by a specific occupant. Therefore, the usable square footage in a structure is what is occupied by an unique renter, inclusive of bathrooms, personal conference spaces, and individual offices.
- Common Area → In contrast, the common area of a building is not rented to a private but is rather available to all renters for cumulative use. These shared areas can include lobbies, parking space, roofing decks, and elevators.
So, who pays for the costs related to maintaining the common area?
Since all tenants deserve to utilize the area, as part of the leasing contract, each of them contribute towards such payments, usually on a pro rata basis.
With those proceeds, the property manager is anticipated by occupants to ensure the typical locations are kept arranged and tidy, while fixing issues or fixing damages.
What Does Common Area Maintenance Include?

The most frequent kinds of typical areas at residential or commercial properties include the following examples:
- 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 circumstances, if the elevator shared by all occupants were to malfunction, the landlord is accountable for fixing the issue quickly.
The stipulation referring to typical location upkeep (CAM) charges is stated in commercial property leases, where the particular terms around the contractual obligations of each party (the lessor and the lessee) are set.
Furthermore, the type of lease signed in between the two celebrations is essential to determining each celebration's respective commitments, e.g. triple web (NNN).
How to Calculate CAM Charges
The CAM charges matter in realty, especially for business 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 many leasing contracts, the renters pay a part of the total CAM on a professional rata basis per the negotiated agreement, i.e. in percentage with the amount of square video leased.
The computation of each occupant's typical location upkeep (CAM) fee, revealed on an annual basis, can be identified by dividing the occupant's square 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 an Occupant into a Month-to-month Fee (Divide by Twelve Months)
Common Area Maintenance Formula (CAM)
The typical area maintenance (CAM) incurred by each tenant is calculated by increasing their particular pro-rata share of expenses by the expected yearly 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 renter CAM charge is an annualized metric, the amount must be divided by twelve to convert into a regular monthly charge.
Conversely, an alternative technique to determine the CAM charges is on a per square foot (sq. ft.) basis, which is done by dividing the estimated yearly CAM charges by the residential or commercial property's leasable square video.
Since CAM costs are most typically assigned based upon the amount of space occupied, the occupants with more space rented will incur more CAM charges (and vice versa).
Common location upkeep is most typically determined on an annualized basis, and after that divided into regular monthly payments attributable to each occupant on a per square foot basis.
Usually at the start of each year, a residential or commercial property owner will forecast the upcoming typical area upkeep (CAM) expenses for the entire residential or commercial property as part of the yearly budget, which affects rates.

Broadly put, CAM charges fall under 2 categories:

1. Controllable Charges → The residential or commercial property owner has direct impact over controllable charges (e.g. administrative expenses, personnel payroll).
2. Uncontrollable Charges → On the other hand, uncontrollable charges, remain outside the residential or commercial property owner's control and are unforeseeable (e.g. snow storm, fire).
However, CAM fee rate caps and floorings can set restraints on just how much lease can be adjusted.
FAQ: Is Capital Investment Included in CAM?
For the a lot of part, capital investment (Capex) are left out from common area upkeep (CAM), depending on the context of the invest.
Why? Capex related the residential or commercial property enhancements, such as building a more modern fitness center for renters, are a type of discretionary spending (and part of the property manager's cost of ownership).
However, certain non-discretionary capital expenses can be categorized as common location upkeep, such as fixing a broken A/C system, which affects all existing (and future) renters.

CAM Charges Calculation Example
Suppose a residential or commercial property owner is approximating the typical location maintenance (CAM) charges expected on their commercial workplace structure for the upcoming year, 2024.
The total annual CAM charges for the whole 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 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 commercial occupant must contribute based upon the quantity of square footage leased each year.
- CAM Charge per Square Footage = $260,000 ÷ 50,000 sq. ft. = $5.20
The estimated CAM charge per square video - $5.20 sq. ft. - should then be allocated in proportion with each renter's pro-rata share.
The pro-rata share is figured out by dividing the private occupant's square video footage by the gross leasable area (GLA) of the office complex.
Therefore, if among 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.
