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.
Self-storage leases govern facilities providing individual storage units rented to consumers and businesses for personal property storage. Self-storage represents a unique lease type in commercial real estate — individual unit leases are typically month-to-month consumer agreements, but ground leases, build-to-suit agreements, and portfolio acquisition leases governing entire self-storage facilities require commercial lease abstraction with a focus on operating metrics, revenue per unit, and management agreement terms.
Individual self-storage unit rentals are simple month-to-month license agreements governed by the state's self-storage act rather than commercial lease law. Leases governing entire self-storage facilities — such as ground leases for development sites or master leases for portfolio acquisitions — are long-term NNN or absolute NNN commercial leases where the operator-tenant is responsible for all operating costs and capital expenditures. Operating agreement and franchise terms for branded self-storage operators may be separate documents requiring simultaneous abstraction.
National self-storage REIT operators (Public Storage, Extra Space, CubeSmart, Life Storage), regional storage operators, and private entrepreneurial self-storage companies. Self-storage operators typically negotiate facility leases as ground leases or triple-net leases on existing buildings, frequently with purchase options reflecting the operator's desire to own stabilized facilities.

Lextract automatically checks self-storage leases against these red flag rules during extraction:
Self-storage facility leases require extraction of revenue-sharing provisions if the landlord participates in rental income above a base threshold, percentage rent mechanisms tied to gross revenue from unit rentals, and any restrictions on rental rate increases that affect the operator's revenue optimization ability. Climate-controlled space provisions, vehicle storage allowances, and outdoor storage areas must be extracted as they significantly affect the facility's revenue potential. Lien law provisions giving the operator rights to auction contents of units with delinquent accounts are governed by state law and typically incorporated by reference rather than stated in full.
Individual self-storage unit rentals are typically month-to-month license agreements (not leases in the traditional sense) governed by state self-storage lien acts. Leases governing entire facilities — for development, acquisition, or long-term operation — are commercial leases with standard commercial lease provisions including renewal options, assignment rights, and NNN expense structures. This guide focuses on facility-level commercial leases, not individual unit agreements.
Purchase options are relatively common in self-storage ground leases and facility leases because operators frequently develop sites they intend to own long-term. A typical structure involves a 20–30 year ground lease with a purchase option exercisable after a stabilization period, priced at a defined capitalization rate applied to net operating income. This allows the operator to control the site during development without committing full acquisition capital upfront.
Some self-storage facility leases include percentage rent provisions where the landlord receives a share of gross revenue above a defined threshold in addition to base rent. Others include revenue reporting requirements that give the landlord visibility into facility performance. Ground leases for self-storage development may tie rent to performance metrics or include escalation tied to revenue growth rather than fixed percentages.
