CAM Charges
Common area maintenance (CAM) charges are fees paid by tenants to cover the cost of maintaining shared spaces in a commercial property, such as parking lots, lobbies, landscaping, and common restrooms. CAM is typically allocated proportionally based on each tenant's share of the total leasable area.
CAM charges are a fundamental component of commercial lease economics, particularly in shopping centers, office buildings, and mixed-use properties. They allow landlords to pass through the actual costs of maintaining common areas to the tenants who benefit from them. Typical CAM expenses include parking lot maintenance and lighting, landscaping, snow removal, common area utilities, janitorial services, security, and property management fees.
CAM is usually structured in one of two ways: actual CAM (tenants pay their proportionate share of actual expenses, which varies year to year) or fixed CAM (tenants pay a predetermined amount that escalates annually by a fixed percentage or CPI). Fixed CAM provides income certainty for the landlord and expense predictability for the tenant. Many institutional landlords prefer fixed CAM because it eliminates the administrative burden of annual reconciliations and provides a built-in profit margin.
For investors analyzing a property, CAM recovery rates are an important metric. If a property's actual common area expenses total $150,000 and CAM reimbursements from tenants total $135,000, the landlord absorbs $15,000 in unrecovered CAM (often from vacant spaces or anchor tenants with CAM caps). Understanding the CAM structure, recovery rate, and any caps or exclusions in tenant leases is essential for accurately projecting operating expenses and NOI.

Triple Net Lease
A triple net lease (NNN) is a lease structure in which the tenant is responsible for paying all three major operating expense categories -- property taxes, insurance, and maintenance -- in addition to base rent. This shifts the majority of operating risk from the landlord to the tenant.
Gross Lease
A gross lease (also called a full-service lease) is a lease structure in which the landlord pays all or most property operating expenses -- including taxes, insurance, maintenance, and utilities -- and the tenant pays a single, all-inclusive rent amount.
Operating Expense Ratio
The operating expense ratio (OER) is the proportion of a property's effective gross income consumed by operating expenses. It indicates how efficiently a property is managed and is used to benchmark expenses against comparable properties.
Tenant Improvement (TI)
Tenant improvements (TIs) are modifications made to a commercial rental space to customize it for a specific tenant's needs. TI costs are typically negotiated as part of the lease and may be funded by the landlord, the tenant, or shared between them.
