What is Common Area Maintenance CAM in Commercial Real Estate Leases?
I've seen many commercial tenants scratch their heads when they first encounter CAM charges on their lease agreements. Let me break down this critical component of commercial real estate leasing that affects both property owners and tenants.
Common Area Maintenance (CAM): Common Area Maintenance (CAM) refers to the shared expenses of maintaining and operating the public spaces in a commercial property, such as parking lots, lobbies, walkways, and landscaping. These costs are typically divided among all tenants based on the percentage of space they occupy in the building.
Understanding CAM Charges
Think of CAM charges like the shared expenses of living in a neighborhood. Everyone chips in to maintain the spaces everyone uses. These areas include:
Parking lots and structures - including repairs, lighting, and snow removal
Lobbies and elevators - cleaning, maintenance, and repairs
Landscaping and outdoor spaces - mowing, planting, and irrigation
Security systems - cameras, personnel, and access controls
HVAC systems in common areas - maintenance and utilities
The math behind CAM charges isn't rocket science, but it does require attention to detail. Your share typically depends on your square footage compared to the building's total leasable area. For example, if you lease 2,000 square feet in a 20,000-square-foot building, you'd pay 10% of the total CAM costs.
Types of CAM Structures
Commercial leases handle CAM charges differently:
Triple Net (NNN) leases: You pay your portion of CAM, property taxes, and insurance separately from base rent. Modified gross leases: Some CAM expenses are included in your base rent, while others are passed through separately. Full-service gross leases: Most CAM charges are built into your base rent. Percentage of sales leases: CAM charges might be tied to your business performance.
Common CAM-Related Issues
I've noticed several recurring challenges with CAM charges. Watch out for:
Unexpected cost increases
Unclear definitions of what constitutes a common area
Disputes over calculation methods
Annual reconciliation surprises
Best Practices for Tenants
Protect your interests by:
Reading your lease carefully - know exactly what you're responsible for
Getting everything in writing during negotiations
Keeping detailed records of all CAM-related communications
Setting aside money monthly for CAM expenses
Best Practices for Landlords
Property owners should focus on:
Clear documentation of all CAM expenses
Regular updates to tenants about maintenance schedules
Fair distribution of costs among tenants
Open communication about upcoming projects or expenses
Common Misconceptions About CAM
Let's clear up some confusion:
Not everything about CAM is negotiable. While some aspects can be discussed, basic maintenance costs are usually non-negotiable.
Each building has its unique CAM structure based on its needs and management style.
CAM covers more than basic maintenance - it often includes capital improvements and specialized services.
Future Trends in CAM
The commercial real estate industry is adapting to new demands:
Green building initiatives: Energy-efficient systems and sustainable practices are becoming standard in CAM programs. Technology integration: Smart building systems are changing how common areas are managed and monitored. Health and safety measures: New cleaning protocols and air filtration systems are now part of many CAM programs.
