Calculating Pass-Through Charges in Commercial Leases

One of the most crucial concepts for both landlords and tenants to understand is pass-through charges. These charges play a significant role in the financial structure of commercial leases and can have a substantial impact on the overall cost of occupancy for tenants. This comprehensive guide will delve deep into the intricacies of pass-through charges, providing real-world examples and practical insights for lease administration professionals.

What Are Pass-Through Charges?

Pass-through charges, also known as operating expenses or additional rent, are expenses incurred by the landlord in the operation and maintenance of a commercial property that are subsequently "passed through" to the tenants. These charges are typically in addition to the base rent and are calculated based on each tenant's proportionate share of the property.

Pass-through charges are common in various types of commercial real estate, including:

  • Office buildings

  • Shopping centers and malls

  • Industrial properties

  • Mixed-use developments

The primary purpose of pass-through charges is to ensure that the landlord can recover the costs associated with operating and maintaining the property while providing a fair and transparent method for allocating these expenses among tenants.

Common Types of Pass-Through Charges

While the specific pass-through charges can vary depending on the property type and lease agreement, some of the most common categories include:

1. Common Area Maintenance (CAM) Charges

CAM charges cover the costs associated with maintaining and operating the common areas of a property. These areas are typically shared by all tenants and may include:

  • Lobbies and corridors

  • Elevators and escalators

  • Restrooms

  • Parking lots and garages

  • Landscaping and exterior maintenance

  • Janitorial services

  • Snow removal (in applicable climates)

  • HVAC systems for common areas

Real-world example: In a multi-tenant office building, the landlord spends $500,000 annually on CAM expenses. These costs include daily cleaning of the lobby and elevators, maintaining the landscaping around the building, and ensuring the proper functioning of the shared HVAC system. Instead of absorbing these costs, the landlord passes them through to the tenants based on their proportionate share of the building.

2. Property Taxes

Property taxes are levied by local governments on commercial properties. These taxes can be a significant expense and are typically passed through to tenants. The amount can vary greatly depending on the property's location, value, and local tax rates.

Real-world example: A shopping center in a prime suburban location has an annual property tax bill of $1,200,000. Rather than incorporating this cost into the base rent, the landlord passes it through to the tenants. A major anchor tenant occupying 30% of the leasable area would be responsible for $360,000 of the property tax bill.

3. Insurance Premiums

Landlords are required to carry various types of insurance on their properties, including:

  • Property insurance

  • General liability insurance

  • Flood insurance (if applicable)

  • Earthquake insurance (if applicable)

  • Workers' compensation insurance

These insurance costs are typically passed through to tenants as part of their operating expenses.

Real-world example: The owner of an industrial park carries a comprehensive insurance policy that costs $250,000 annually. This cost is divided among the tenants based on their occupied square footage. A tenant leasing a 50,000 sq. ft. warehouse in a 500,000 sq. ft. industrial park would be responsible for 10% of the insurance premium, or $25,000 per year.

4. Utilities

While some leases may require tenants to contract directly with utility providers, others include utility costs as part of the pass-through charges. This is particularly common in office buildings or shopping centers where individual metering may not be feasible. Utilities often included in pass-through charges are:

  • Electricity

  • Water and sewer

  • Natural gas

  • Trash removal

Real-world example: In a multi-tenant office building, the landlord receives a monthly electricity bill for $30,000. Instead of trying to submeter each individual office suite, the landlord includes electricity as a pass-through charge. Tenants pay their share based on their occupied square footage, with adjustments made for any high-consumption tenants (e.g., those with data centers or 24/7 operations).

5. Security Services

Many commercial properties require security services to ensure the safety of tenants and their customers or employees. These costs can include:

  • Security personnel

  • Surveillance systems

  • Access control systems

  • Emergency response systems

Real-world example: A downtown office tower employs a 24/7 security team and maintains an advanced access control system. The annual cost for these security measures is $400,000. This expense is passed through to tenants, with each tenant contributing based on their percentage of occupancy in the building.

Calculating Pass-Through Charges

The method for calculating pass-through charges can vary depending on the lease agreement, but the most common approach is based on the tenant's pro rata share of the property. This is typically determined by the ratio of the tenant's leased space to the total rentable area of the property.

Basic Formula for Calculating Pass-Through Charges

Tenant's share of pass-through charges = (Tenant's leased square footage / Total rentable square footage of the property) * Total pass-through charges

Detailed Example Calculation

Let's consider a more complex example to illustrate how pass-through charges are calculated in practice:

Property Details:

  • Total rentable area: 100,000 sq. ft.

  • Tenant A occupies: 20,000 sq. ft.

  • Tenant B occupies: 30,000 sq. ft.

  • Tenant C occupies: 50,000 sq. ft.

Annual Operating Expenses:

  • CAM: $500,000

  • Property Taxes: $750,000

  • Insurance: $150,000

  • Utilities: $300,000

  • Security: $100,000

Total Pass-Through Charges: $1,800,000

Calculation of Each Tenant's Share:

  1. Tenant A (20% of total area): (20,000 / 100,000) * $1,800,000 = $360,000

  2. Tenant B (30% of total area): (30,000 / 100,000) * $1,800,000 = $540,000

  3. Tenant C (50% of total area): (50,000 / 100,000) * $1,800,000 = $900,000

In this example, each tenant's annual pass-through charges would be added to their base rent. For instance, if Tenant A's annual base rent is $600,000, their total annual rent including pass-through charges would be $960,000.

Additional Considerations in Pass-Through Charges

1. Gross Leases vs. Net Leases

The structure of pass-through charges can vary depending on the type of lease:

  • Gross Lease: In a gross lease, the base rent typically includes most or all operating expenses. Any pass-through charges are usually limited to increases over a base year or expense stop.

  • Net Lease: In a net lease (e.g., triple net or NNN lease), the tenant pays a base rent plus their proportionate share of most or all operating expenses as pass-through charges.

Real-world example: A tenant signs a gross lease for office space with a base year of 2023. In 2024, if the property's operating expenses increase by $2 per square foot compared to the base year, the tenant would be responsible for their proportionate share of this $2 per square foot increase as a pass-through charge.

2. Expense Caps and Exclusions

Many lease agreements include provisions that limit the landlord's ability to pass through certain expenses or cap the annual increases in pass-through charges.

Real-world example: A retail lease might stipulate that CAM charges cannot increase by more than 5% per year. If actual CAM expenses increase by 7%, the landlord can only pass through a 5% increase to the tenant, absorbing the additional 2% increase.

3. Audit Rights

Most commercial leases grant tenants the right to audit the landlord's books and records related to pass-through charges. This ensures transparency and allows tenants to verify that they are being charged correctly.

Real-world example: A large office tenant exercises their audit rights and discovers that the landlord has been incorrectly allocating certain executive salaries to the building's operating expenses. As a result of the audit, the tenant receives a refund for overpaid pass-through charges and the landlord adjusts their accounting practices going forward.

4. Reconciliation Process

At the end of each year, landlords typically provide tenants with a reconciliation statement that compares the estimated pass-through charges paid by the tenant throughout the year with the actual expenses incurred. This process may result in additional charges or credits to the tenant.

Real-world example: A shopping center tenant pays estimated CAM charges of $10,000 per month throughout the year. At year-end, the reconciliation shows that actual CAM expenses attributable to the tenant were $115,000. The tenant would then owe an additional $5,000 to cover the shortfall.

Best Practices for Managing Pass-Through Charges

For lease administration professionals, effectively managing pass-through charges is crucial for maintaining positive landlord-tenant relationships and ensuring financial accuracy. Here are some best practices to consider:

  1. Maintain Detailed Records: Keep comprehensive records of all expenses related to pass-through charges, including invoices, payment records, and allocation calculations.

  2. Provide Clear Communication: Regularly communicate with tenants about pass-through charges, including providing detailed breakdowns of expenses and explanations for any significant changes.

  3. Implement Strong Accounting Systems: Use robust accounting software that can accurately track and allocate pass-through charges to individual tenants.

  4. Conduct Regular Internal Audits: Periodically review your pass-through charge calculations and allocations to ensure accuracy and compliance with lease terms.

  5. Stay Informed About Market Standards: Keep up-to-date with industry standards and best practices regarding pass-through charges in your specific market and property type.

  6. Be Prepared for Tenant Audits: Maintain organized and easily accessible records to facilitate any tenant audits of pass-through charges.

  7. Consider Expense Management Strategies: Implement cost-saving measures and efficient property management practices to help control operating expenses and minimize pass-through charges.

Pass-through charges are a fundamental aspect of commercial real estate leases, playing a crucial role in the financial relationship between landlords and tenants. By understanding the types of pass-through charges, calculation methods, and best practices for management, lease administration professionals can ensure fair and transparent allocation of operating expenses.

As the commercial real estate landscape continues to evolve, staying informed about pass-through charges and related lease provisions is essential for both landlords and tenants. By mastering this aspect of lease administration, professionals can contribute to more efficient property management, reduced disputes, and ultimately, more successful landlord-tenant relationships.
