What Is a Commercial Lease? Key Terms, Types, and What to Watch For
A commercial lease is a legally binding contract between a landlord and a business tenant. Learn the key terms, lease types, and critical clauses before you sign.
Montana provides a highly contract-driven, landlord-neutral commercial leasing environment shaped by its rural agricultural economy, vast geographic scale, and relatively small total commercial real estate market. Commercial landlord-tenant relationships are governed primarily by the Montana Residential Landlord and Tenant Act (MCA Title 70, Chapter 24) and the general property statutes under MCA Title 70. For commercial leases, Montana courts overwhelmingly defer to the express terms of the agreement, applying general contract law principles and common-law property doctrine where the lease is silent.
Montana does not permit self-help commercial evictions; landlords must pursue formal unlawful detainer proceedings. The state's commercial market is driven by agriculture, ranching, timber, mining, and a growing outdoor recreation and tourism economy. Commercial leases for properties adjacent to or used in agricultural and ranching operations—grain storage, livestock facilities, irrigation equipment shops, and outfitter operations—carry specialized norms that differ significantly from urban commercial leases. The Billings, Bozeman, Great Falls, and Missoula markets represent the primary urban commercial real estate centers, with Bozeman experiencing significant tech and high-amenity commercial growth driven by in-migration.
While primarily residential, this act informs commercial lease practice by providing baseline landlord obligation and notice standards in Montana.

No statutory right; entirely governed by the negotiated lease.
Montana provides no statutory audit rights for commercial tenants with respect to CAM charges or operating expense reconciliations. All audit rights must be explicitly negotiated and documented in the lease agreement. Given Montana's market characteristics—often smaller, non-institutional landlords and relatively informal lease structures—tenants in NNN or modified gross leases should ensure audit provisions are clearly defined, as informal operating expense pass-throughs are common and may lack documentation standards found in larger markets.
