When a commercial lease starts to unravel, the questions tend to come fast: Can the landlord lock the space? Does the tenant still owe rent after moving out? Are CAM charges really allowed? What happens if the business wants to assign the lease, negotiate a surrender, or raise repair issues as a defense?
Those questions often show up at the exact moment the stakes are highest. A missed notice deadline, a poorly documented default, or a misunderstood lease clause can shift leverage quickly. And because commercial leasing is driven heavily by contract language and state law, the answer is often less about “fairness” and more about what the lease actually says, what notices were sent, and what happened next.
In this post you’ll learn the 10 questions landlords and tenants ask most often when a business lease relationship breaks down, along with the legal issues that frequently shape those disputes. If you want a broader overview of how defaults, expense disputes, transfers, and eviction risk fit together, this plain-English overview of business lease conflicts can help set the stage.

Commercial lease disputes rarely involve just one issue. A rent default may turn into a fight over notices. A maintenance complaint may become a claim about quiet enjoyment. A proposed sublease may trigger a separate dispute over consent rights. And a disagreement over additional rent can become a full-blown possession case.
That pressure is easier to understand in the context of the current rental environment. The U.S. Census Bureau reported that real median gross rental costs rose 3.8% in 2023, the largest annual real increase since at least 2011, and its more recent county-level release found renters paying about $100 more per month in the 2020–2024 period than in 2015–2019. (U.S. Census Bureau, U.S. Census Bureau) While those figures are not limited to commercial space, they reflect a broader cost environment that often makes lease disputes more financially sensitive for both property owners and business tenants.
Usually, the first question is practical: Can the landlord change the locks, shut off access, or remove property?
In general terms, that depends heavily on state law, local procedure, and the lease. Across U.S. landlord-tenant law, eviction rules are largely governed by state statutes, local ordinances, court rules, and common law, and in many jurisdictions a court order is part of the possession process. (Cornell Law School Legal Information Institute, Cornell Law School Legal Information Institute) Legal guides discussing lockouts also note that “self-help” evictions are widely restricted and can expose landlords to penalties.

Commercial tenancies can be more complicated than residential ones because some states treat business leases differently, and some leases contain specific re-entry provisions. Even so, many lockout disputes turn on very specific questions:
For landlords, a mistaken lockout can create exposure beyond unpaid rent. For tenants, waiting too long to challenge a lockout can make recovery of records, inventory, and operations much harder. That is one reason many businesses start organizing documents early, including notices, payment history, lease amendments, and correspondence.
A lot of people assume default means nonpayment of rent. It often does, but commercial leases usually define default more broadly.
