Negotiating the operating expense section of a lease can be one of the most complex and overlooked parts of a commercial lease. Whether you’re signing a new lease or renewing an existing one, learning how to negotiate operating expenses effectively can make a significant difference over time.
Here are several practical tips to help tenants secure a fair deal and avoid surprise expenses, especially in triple-net (NNN) leases, where operating costs are passed through to the tenant.
1. Understand What’s Included in Operating Expenses
Before signing a lease, tenants should have a clear understanding of what counts as operating expenses. These costs vary widely by property and may include maintenance, landscaping, insurance, taxes, and management fees.
Always request an operating expense budget from the landlord before signing. This gives you a starting point for comparison and helps you identify red flags.
For example: A 10-Year Cost Comparison
Let’s say you’re a 10,000 SF tenant comparing two buildings. Both have a 5% annual increase in expenses, but one starts at $10/SF and the other at $15/SF. The long-term difference is massive.
That’s a difference of over $628,000 over the term purely based on operating expenses.
Even with identical square footage, your OpEx structure can make or break your deal. That’s why reviewing this section carefully, or better yet, working with professionals, is critical.
2. Negotiate a Cap on Annual Increases
One of the most effective protections a tenant can negotiate is a cap on year-over-year increases in operating expenses.
A cap helps prevent significant rent hikes if operating costs spike unexpectedly. Most landlords are more flexible on controllable expenses (such as janitorial, landscaping, or management fees) and less so on uncontrollable expenses like utilities, insurance, or property taxes.
We typically suggest tenants propose a 4% non-cumulative cap on controllable expenses. Landlords may counter with a cumulative cap of 4–8%, which still offers meaningful protection. If a landlord refuses any cap, it may be a red flag that they lack strong cost controls.
3. Limit Capital Repairs and Improvements
Capital repairs are major improvements that increase the property’s value, such as lobby remodels, roof replacements, or new HVAC systems. These are different from regular maintenance.
Tenants should push to limit the types of capital costs passed through. A good rule: only allow capital costs that either reduce future operating expenses or are legally required after the lease is signed (such as ADA compliance or energy efficiency upgrades).
You don’t want to end up paying for a new gym or high-end finishes that don’t benefit your business.
4. Get Professional Help
Leases, especially the operating expense section, are dense and often written in landlord-friendly language.
Consider hiring a commercial real estate broker or real estate attorney. These professionals know what to look for, what’s typical in the market, and how to push back effectively during negotiations.
It’s a small investment that can lead to major long-term savings.
5. Audit Your Lease Annually
After you sign, don’t assume everything will run smoothly. Operating expenses should be reviewed every year.
Make sure the landlord’s reconciliation and annual budget match your lease terms. Even if a lease has protections in place, landlords can make mistakes and often do.
