Commercial leases contain dozens of provisions that interact in complex ways. This guide explains the key terms every tenant must understand before signing. For full negotiation strategy, see our Commercial Lease Negotiation Guide.

Modern commercial office space

In a NNN lease, the tenant pays base rent plus property taxes, insurance, and common area maintenance (CAM). This shifts most operating costs to the tenant. NNN leases are standard in retail and industrial but negotiable in office leasing.

Common Area Maintenance charges cover shared expenses like landscaping, parking lot maintenance, security, and building systems. The International Council of Shopping Centers reports CAM disputes are among the most common landlord-tenant conflicts. Always negotiate audit rights and expense caps.

Escalation clauses increase rent over the lease term through fixed annual increases (e.g., 3% per year), CPI adjustments tied to the Consumer Price Index, or percentage rent based on gross sales. Each method has different risk profiles for tenants.

A TI allowance is the landlord's contribution toward customizing the space for your business. Allowances are negotiable and typically expressed as a per-square-foot amount. Higher TI allowances often come with longer lease terms or higher base rent.

Assignment and subletting rights provide flexibility if your business needs change. Landlord-drafted leases typically restrict these rights heavily. Clark Meyers PC negotiates reasonable assignment provisions including rights to assign to affiliates and successors.

An exclusive use clause prevents the landlord from leasing to a direct competitor within the property or shopping center. These are critical for retail tenants and negotiable for office and professional services tenants.

Landlords often require business owners to personally guarantee the lease. This means your personal assets are at risk if the business defaults. Clark Meyers PC negotiates guarantee limitations including burn-off provisions that reduce personal exposure over time.

Tenant remedies for landlord defaults should include rent abatement for service failures, self-help rights for emergency repairs, and termination rights for extended disruptions. Most landlord-drafted leases limit these remedies significantly.

Optimal lease terms balance stability with flexibility. Longer terms provide rent certainty and amortize TI costs but reduce flexibility. Shorter terms with renewal options provide more adaptability. Our commercial real estate practice advises on the right balance for your situation.

Key red flags: unrestricted relocation rights, demolition clauses, radius restrictions, automatic renewal with above-market escalations, and personal liability extending beyond the lease term. See our lease negotiation guide for details.
