Understanding your commercial lease economics begins with clarity. Every tenant should know how CAM (Common Area Maintenance), TI (Tenant Improvements), and Escalations influence total occupancy expenses and long-term financial planning.
Core Terms That Define Your Lease
Common Area Maintenance (CAM)
Common Area Maintenance charges represent shared operating expenses across all tenants in a commercial property. These costs typically include landscaping, lighting, parking lot maintenance, building security, janitorial services, and property management fees.
Understanding operating expenses and how they are allocated is essential. Tenants should confirm:
- Which expenses are included or excluded
- Whether annual CAM increases are capped
- How their pro rata share is calculated
CAM may also include property insurance, shared utilities, and administrative fees. Since landlords often define CAM differently, tenants should review this section carefully to avoid unexpected costs.
According to BOMA International, properties with transparent CAM accounting experience lower tenant turnover and improved retention.
Tip: Always ask if your lease allows for a CAM audit or requires landlords to provide an annual operating expense reconciliation.
Tenant Improvements (TIs)
Tenant Improvements refer to modifications that tailor the leased space to a tenant’s business needs. Examples include new offices, upgraded flooring, lighting, HVAC systems, or customized build-outs for retail and office tenants.
The Tenant Improvement Allowance (TIA) is the landlord’s contribution toward those upgrades. Common TI structures include:
- Turnkey Build-Outs: The landlord manages and delivers the completed space.
- Reimbursement Model: The tenant completes construction and receives repayment within a fixed amount.
- Carryover Rights: Unused allowance funds can sometimes offset rent.

Escalations
Lease escalations determine how rent or expenses increase over the lease term. They protect landlords from inflation while providing tenants with predictability.
Common escalation structures include:
- Fixed percentage increases (for example, 3 percent annually)
- CPI (Consumer Price Index) adjustments (rent tied to inflation)
- Operating expense escalations (rent adjusted based on actual property cost changes)
Tenants can negotiate escalation caps or hybrid clauses that limit volatility. Over time, small percentage differences can lead to major cost variations, so understanding each clause matters.
The NAIOP Research Foundation found that tenants represented by brokers reduce total occupancy costs by an average of 12 percent over their lease term.
Market Forces Redefining Lease Economics
The commercial real estate environment is evolving. Sustainability, data transparency, and flexibility are redefining how tenants evaluate lease costs such as CAM, TI, and escalations.
Emerging Influences:
- Sustainability and efficiency: energy-efficient systems reduce long-term CAM expenses.
- Smart building data: automation improves operating expense tracking.
- Flexible lease models: shorter, renewable terms support cost predictability.
- Tenant experience: amenity-driven environments increase retention rates.
The CBRE U.S. Real Estate Market Outlook 2024 highlights that sustainable and amenity-rich properties achieve faster lease-up times and higher renewal rates.
Regional Insights: Cost Trends Across Key Markets
Southern California – Logistics and industrial absorption continues to drive demand. CAM expenses are rising slightly due to energy and infrastructure upgrades.
Texas Sunbelt – Corporate relocations have fueled higher TI allowances and shorter lease terms.
Mid-Atlantic – Life-science growth has increased specialized build-out costs and escalations tied to equipment maintenance.
KEYZ Commercial Note:
Tenants expanding across multiple markets should benchmark operating expenses per square foot alongside escalation formulas to maintain predictable lease performance.
