Commercial leases are complex legal documents that most business owners encounter with limited preparation. Understanding the key terms before sitting down with a landlord or reviewing a lease proposal puts you in a dramatically better negotiating position — and helps you avoid the costly misunderstandings that trap many commercial tenants. Here is a plain-language guide to the terms that matter most.

Base Rent and Escalation

Base rent is your core monthly occupancy cost, typically expressed in dollars per square foot per year. Annual escalation clauses specify how base rent increases each year — typically by a fixed percentage (2-3% is standard) or tied to a cost-of-living index. Always understand both your starting rent and how fast it grows: a low starting rate with aggressive escalation can become expensive over a multi-year lease.

Net Lease vs. Gross Lease

In a gross lease, your monthly payment covers most or all operating costs including taxes, insurance, and maintenance. In a net lease (including single net, double net, and triple net variants), you pay base rent plus some or all of those costs separately. Always calculate your total monthly occupancy cost — not just base rent — when comparing options.

Tenant Improvement Allowance and Buildout

A tenant improvement (TI) allowance is a landlord contribution toward customizing the space for your use. The TI allowance is often negotiable and can significantly offset your upfront setup costs. Understand exactly what the allowance covers, whether unused amounts revert to the landlord, and what happens if your actual buildout costs exceed the allowance.

Common Area Maintenance (CAM) Charges

CAM charges cover your proportionate share of maintaining shared areas like parking lots, landscaping, and common spaces. These are often underestimated in total occupancy cost calculations. Ask for a detailed breakdown of what is included in CAM and what the annual cap on increases is.
