Operating Costs in a Commercial Lease: What They Include and How They Are Calculated
When a business owner assesses whether they can afford a commercial space, they typically start with the monthly rental figure. That figure is the most visible cost in the lease and the one most prominently quoted when a space is marketed. It is also, in many commercial leases, not the full story.
Operating costs are charged to tenants separately from base rental in most commercial leases structured on a net basis. Depending on the building, the lease terms, and the composition of those costs in any given year, operating cost recoveries can add a material amount to what you actually pay each month, and that amount can increase independently of your rental escalation.
Understanding what operating costs are, what they include, and how they are calculated before you sign is one of the most practical steps a commercial tenant can take to avoid financial surprises once they are in occupation.
Operating costs are charged to commercial tenants in addition to base rental and can significantly increase your monthly liability.
What operating costs are
Operating costs, sometimes referred to in leases as outgoings, service charges, building levies, or recoveries, are the costs a landlord incurs in running, maintaining, and managing a commercial building. Rather than absorbing these costs as a property owner, the landlord recovers them from tenants in proportion to the floor area each tenant occupies relative to the building as a whole.
The principle behind operating cost recovery is that tenants, as the users of the building and its common areas and services, contribute to the cost of keeping those services operational. In a fully let multi-tenant building, the total operating cost is distributed across all tenants. If a building has a single tenant occupying the entire floor area, that tenant typically carries the full operating cost.
The key distinction is between a gross lease and a net lease. In a gross lease, operating costs are built into the base rental, the landlord has estimated what those costs will be and incorporated them into the rental figure. In a net lease, the base rental and operating costs are separate line items, and the tenant pays both. Many commercial leases in South Africa are structured on a net or modified net basis, which means operating costs are recovered in addition to the rental you agreed to pay.
What operating costs typically include
The specific composition of operating costs varies between buildings and between leases, but most commercial operating cost schedules include the following categories. Municipal rates and taxes are typically the largest single component. These are the charges levied by the local municipality on the property and are passed through to tenants as a recoverable cost. Municipal rates can increase significantly from one year to the next, particularly following a municipal revaluation, and those increases flow directly into the operating cost recovery without being subject to the escalation cap that applies to base rental.
Building insurance covers the landlord’s insurance of the building structure itself, not the tenant’s contents or liability, which the tenant is responsible for separately. The building insurance premium is a recoverable operating cost in most commercial leases.
Common area cleaning covers the maintenance and cleaning of all shared spaces in the building, lobbies, corridors, ablutions, and any other areas used by multiple tenants. Security costs cover the provision of access control, security personnel, and monitoring systems for the building and its common areas.
Utilities for common areas,electricity and water consumed in shared spaces rather than within individual tenancies are typically recovered as part of operating costs. Lifts, escalators, and other mechanical services in common areas carry their own maintenance and service contract costs, which are also commonly included.
Building management fees are charged by the managing agent or property management company responsible for administering the building on behalf of the landlord. These fees cover the day-to-day management of the property, including tenant liaison, maintenance coordination, and financial administration. Management fees are a legitimate recoverable cost, but their structure and rate are worth checking in the lease, particularly where the landlord manages the property through a related entity.
Grounds and landscaping maintenance covers the upkeep of any external areas, gardens, or parking areas associated with the building. Pest control and general building maintenance costs are also commonly included, subject to what the lease specifies.
What operating costs typically exclude
Not all building-related costs are recoverable from tenants, and understanding what sits outside the operating cost schedule is as important as understanding what sits inside it. Capital expenditure, the cost of major structural repairs, roof replacements, or significant building upgrades, is generally not recoverable as an operating cost. The distinction between maintenance and capital expenditure is not always clear-cut and can be a source of dispute between landlords and tenants. A landlord who includes the cost of a roof replacement in the annual operating cost recovery is doing something that most leases do not permit, and that a tenant has grounds to challenge if the lease draws a clear line between operating costs and capital items.
Costs that relate specifically to the landlord’s obligations under the lease , rather than to the general running of the building, are also generally not recoverable. If the landlord has a maintenance obligation under the terms of the lease, the cost of meeting that obligation is their liability, not a shared cost to be recovered from tenants.
How operating costs are calculated and recovered
The mechanics of operating cost recovery are set out in the lease, and the detail matters. The most common approach in multi-tenant commercial buildings is a proportionate recovery based on the tenant’s share of the gross leasable area of the building. If a building has a total leasable floor area of 5 000 square meters and you occupy 500 square meters, your proportionate share of the total operating cost is ten percent.
In practice, most leases require tenants to pay an estimated monthly operating cost amount based on the landlord’s budget for the year ahead. At the end of the financial year, the landlord prepares a reconciliation statement comparing the actual operating costs incurred against the estimated amounts recovered from tenants. Where the actuals exceed the estimates, tenants are billed for the shortfall. Where the actuals are lower than the estimates, tenants receive a credit or a refund.
This means your monthly operating cost payment is provisional, not final, and the annual reconciliation can produce an additional liability that was not accounted for in your monthly budget. Understanding how the reconciliation process works, and what the lease says about the timing and format of reconciliation statements, is an important part of understanding your total cost exposure.
Audit rights
Many commercial leases give tenants the right to audit the landlord’s operating cost accounts, to inspect the underlying records and verify that the costs being recovered are legitimate, accurately calculated, and consistent with the lease terms. Audit rights are a meaningful protection for tenants, particularly in larger buildings where operating costs represent a significant monthly liability.
Check whether your lease includes an audit right, what the process for exercising it is, and what timeframe applies. Some leases require the tenant to raise any dispute about the operating cost reconciliation within a specified period after the statement is issued, typically 30 to 90 days. Missing that window can limit your ability to challenge a recovery you believe is incorrect.
What to check in the lease before you sign
Before signing a commercial lease that includes operating cost recovery, there are five things worth checking in the lease document.
The definition of operating costs matters. A broad definition that includes costs without specific exclusions gives the landlord significant discretion over what is recovered. A well-defined schedule with clear inclusions and exclusions gives the tenant a predictable liability. Whether operating cost recoveries are capped matters. Some leases cap the annual increase in operating costs at a fixed percentage or link it to CPI. A cap limits your exposure to unexpected cost escalation in any given year. Many leases do not include a cap, which means municipal rates increases, insurance premium hikes, or increased security costs can pass through to tenants without limit.
The reconciliation process and its timing matter. Understand when the annual reconciliation statement will be issued, how long you have to dispute it, and what the process is for resolving disagreements about the operating cost accounts. Whether management fees are included and how they are calculated matters. A management fee expressed as a percentage of total operating costs creates a structure where the managing agent’s fee increases as operating costs increase, which is worth being aware of. Your audit right and the process for exercising it matters. If the lease includes one, know how to use it. If it does not, consider whether that is a point worth raising before you sign.
Getting your commercial lease reviewed
Operating costs are one of the most consistently misunderstood elements of commercial tenancy. The monthly liability they create is real, it can be significant, and it is one of the areas where the difference between what tenants expect to pay and what they actually pay tends to be largest.
A commercial lease review covers the full operating cost structure of your agreement, what is included, how it is calculated, whether any caps or protections apply, and what the reconciliation process means for your annual liability.
