Commercial Lease Checklist: What Owners Should Confirm Before Signing

Every clause in a commercial lease eventually becomes an operational obligation — something a property manager has to track, bill, or enforce for years. Reviewing a lease with that in mind, before signing, prevents a lot of downstream friction.

Rent structure and escalations

Confirm the lease type (gross, modified gross, net, or triple net) and the exact escalation schedule — fixed percentage, CPI-indexed, or stepped increases at specific dates. Vague or missing escalation language is one of the most common sources of lost revenue over a long lease term.

CAM and operating cost terms

Confirm exactly which cost categories are recoverable, which are explicitly excluded, and how the tenant's pro-rata share is calculated. If the lease is silent or ambiguous on any of these, resolve it in the lease language now — not during a reconciliation dispute three years in.

Renewal options and notice periods

Note every renewal option, the notice window required to exercise it, and any rent adjustment tied to the renewal term. These dates need to go directly into a lease abstract and tracking system the day the lease is signed — a missed renewal notice deadline can mean losing negotiating leverage or losing the tenant relationship entirely.

Tenant improvement (TI) allowance terms

If the lease includes a TI allowance, confirm the total amount, what it can be used for, the process for approving contractor work, and what happens to any unused allowance. Poorly defined TI terms are a common source of disputes during build-out.

Maintenance and repair responsibility

Confirm exactly which party is responsible for which building systems — HVAC, structural, roof, plumbing — since ambiguity here creates disputes precisely when something breaks and neither party wants to pay for it.

Insurance and indemnification requirements

Confirm the tenant's required insurance coverage and limits are actually specified, and build a process to collect and track certificates of insurance on an ongoing basis, not just at lease signing.

Assignment and subletting terms

Confirm what rights the tenant has to assign or sublet the space, and what landlord approval process applies — this matters more than owners often expect if a tenant's business changes hands during the lease term.

Why this matters for ongoing management

A well-drafted lease makes property management dramatically easier — every ambiguity resolved at signing is one less dispute during the lease term. A poorly drafted one creates years of avoidable friction that a manager has to navigate around instead of simply enforcing.
