For many multi-location operators, Common Area Maintenance (CAM) expenses represent one of the largest, and least scrutinized, occupancy costs in the portfolio.
Most organizations review CAM reconciliations before approving payment. Fewer conduct comprehensive audits. Even fewer know whether their current review process is recovering the value it should.
The question isn't simply whether CAM charges are reviewed. It's whether they're reviewed thoroughly enough to identify costly discrepancies before they become recurring expenses.
Understanding the Difference
Internal CAM reviews and formal CAM audit support share a common goal: verifying that occupancy costs are accurate. The difference lies in depth. An internal review often focuses on confirming invoices, validating calculations, and ensuring payments align with expected charges. CAM audit support goes further — it compares landlord billings against lease provisions, evaluates supporting documentation, identifies potential overcharges, and investigates discrepancies that might otherwise go unnoticed.
Both approaches have value. The right choice depends on the complexity of the portfolio, available internal resources, and the organization's risk tolerance.
Where Internal Reviews Work Well
Many organizations successfully manage routine CAM reviews internally. For smaller portfolios with standardized lease structures, experienced accounting or real estate teams can often identify obvious issues before payments are approved.
Internal reviews typically provide:
- Faster invoice processing
- Lower administrative costs
- Familiarity with portfolio history
- Direct coordination between departments
For organizations with limited portfolio complexity, this may be sufficient. The challenge begins as portfolios grow.
Why Margin Often Slips Away
CAM discrepancies are rarely the result of a single large billing error. More often, they accumulate through small inconsistencies across multiple locations, including:
- Expenses allocated differently than permitted by the lease
- Capital expenditures included in CAM recoveries
- Administrative fees exceeding negotiated limits
- Incorrect allocation percentages
- Charges that continue after lease amendments change responsibility
Individually, these discrepancies may appear insignificant. Across dozens or hundreds of locations, however, they can represent meaningful financial leakage. Because these costs recur annually, a missed issue today may continue affecting occupancy costs for years.
When Independent CAM Audit Support Adds Value
Organizations often benefit from additional audit support when they are:
- Managing large or geographically dispersed portfolios
- Operating under multiple landlord relationships
- Experiencing frequent acquisitions
- Managing complex lease provisions
- Preparing for refinancing, acquisitions, or due diligence
- Lacking dedicated internal lease administration resources
Independent audit support provides a fresh review of landlord billings while applying consistent interpretation across the portfolio. Rather than replacing internal teams, it complements them by providing specialized expertise and additional capacity.
The Bottom Line
Effective CAM management isn't about questioning every invoice. It's about ensuring occupancy costs accurately reflect the agreements you've negotiated — whether that happens through internal resources, specialized CAM audit support, or a combination of both.
The most successful organizations build review processes that prioritize consistency, documentation, and long-term financial accuracy, not simply faster approvals.
