Once a year, many tenants receive a bill for operating expenses. It can be long, confusing, and easy to approve without reading. That's a mistake, because the reconciliation is where small errors and unexpected charges often hide.
Start by comparing this year's charges with last year's. Look for large jumps, new categories, and costs that seem unrelated to your building. A change that looks minor on one line can signal a bigger issue when you add it up across the statement.
Next, check the lease. Confirm that each charge is allowed under the lease language, that the calculation follows the agreed method, and that your share is correct. Pay attention to how the building's total expenses are determined, how common area costs are allocated, and whether any exclusions apply.
If anything is unclear, ask the landlord for supporting invoices or a breakdown of the charges. Reasonable requests for documentation are a normal part of the process. Landlords who answer quickly and clearly are usually the ones with nothing to hide.
Many leases also give tenants the right to audit the expense records within a set window. If the numbers don't add up, use that right. A review often takes a few hours and can catch errors that would otherwise go unnoticed for years.
