If you’re a business tenant, you’ve probably seen your operating expenses tick up over the years. We all have. But do you know *how* that increase is calculated, and what’s driving it? It’s often tied to a "base year" in your lease, a concept that can feel a bit like reading hieroglyphs. We found a great article that really breaks down how base years function in operating expense escalations, making it much clearer to understand the financial impact on our bottom line.

The piece clearly illustrates how a tenant's share of increased operating costs is calculated. For instance, if your lease specifies a base year of 2022, any operating expenses *above* what was spent in 2022 become your responsibility, proportional to your leased space. The article uses a straightforward example to show how this works over time, helping us visualize how those seemingly small annual increases can add up. It’s particularly helpful for understanding why your operating expense pass-throughs might be what they are, and what to expect as your lease continues.

Understanding your base year is crucial, especially if you're approaching a lease renewal or negotiating new terms. Knowing how operating expenses are escalated gives us a better footing to discuss these costs with our landlord. It’s also worth considering whether it’s possible to negotiate a different base year if you’re renewing, or even an expense stop, which is another way to cap your exposure. Have you ever tried to reset your base year mid-lease, or negotiated an expense stop? We’d love to hear your experiences and insights in the forum.
