  • Rent escalation clauses can substantially increase your occupancy costs over a multi-year term.
  • Exit provisions, subletting rights, and personal guarantees deserve the same scrutiny as base rent.
  • A commercial real estate attorney should review any lease before execution.

Why Commercial Lease Review Demands More Rigor Than Residential

Commercial leases are not standardized the way residential agreements often are. Landlords typically draft them to protect their own interests, and nearly every clause is negotiable — but only if you identify the issues before signing. Unlike residential tenants, commercial tenants generally have fewer statutory protections, which means the written contract governs almost everything.

If you're new to this terrain, the Commercial Real Estate for First-Time Learners provides useful grounding on how leasing and valuation work before you engage with a specific property. For a plain-English explanation of terms you'll encounter in the lease itself — cap rates, triple-net, NNN, CAM — consult The Language of Commercial Real Estate: A Plain-English Glossary.

Use this checklist as a structured review tool. Work through it methodically, and engage a qualified commercial real estate attorney before you execute any lease.

Required

Commercial Real Estate Attorney

Review and negotiate lease terms, personal guarantees, and exit clauses on your behalf before signing.

Required

Commercial Property Inspector

Conduct a thorough physical inspection of HVAC, electrical, structural, and roofing systems.

Required

Local Zoning Office / Municipal Records Portal

Verify zoning classification, permitted uses, and any outstanding code violations for the property address.

Optional

Tenant Representative Broker

Provide market comparables, negotiate on your behalf, and identify off-market spaces that better fit your needs.

Optional

Accountant or Financial Adviser

Model total occupancy costs over the full lease term, including escalations and operating expense exposure.

The Checklist

The items below are organized into four critical areas: property and zoning fundamentals, financial obligations, lease structure and flexibility, and physical condition of the space. Address each category before entering final negotiations.

Property & Zoning Fundamentals

Confirm zoning classification with the local municipality and verify it explicitly permits your business type and operations. Must
Check whether any special use permits, conditional use permits, or variances are required — and who is responsible for obtaining them. Must
Verify ADA (Americans with Disabilities Act) compliance obligations and identify which party — landlord or tenant — bears responsibility for any required upgrades. Must
Research whether the building or area has any deed restrictions, environmental liens, or pending code violations that could affect operations. Must
Confirm that parking supply, loading access, and signage rights are adequate for your business and explicitly described in the lease. Should

Financial Obligations & Operating Costs

Identify the lease type (gross, modified gross, or net/NNN) and understand exactly which operating expenses — property taxes, insurance, common area maintenance — you will pay. Must
Request a full breakdown of current CAM (Common Area Maintenance) charges and review whether caps on annual CAM increases are included. Must
Examine rent escalation clauses, including any fixed annual increases or CPI (Consumer Price Index) adjustments, and calculate total cost over the full lease term. Must
Clarify the security deposit amount, conditions for its return, and whether any portion is non-refundable. Must
Determine who is responsible for utilities, HVAC maintenance, structural repairs, and roof — verify these are explicit in the lease, not assumed. Must
Request two to three years of actual operating expense statements from the landlord to benchmark stated costs against historical reality. Should

Lease Structure, Flexibility & Exit Rights

Review the lease term length relative to your business plan and negotiate renewal options — including the rent rate at renewal — in writing. Must
Examine any personal guarantee clause carefully; understand what assets you are pledging and whether a 'good-guy' clause (limiting liability upon proper notice and surrender) is available. Must
Confirm subletting and assignment rights — the ability to transfer your lease to another party — and the conditions or landlord approval required. Must
Identify termination and early exit provisions, including any break clauses, penalties, and notice periods required. Must
Review exclusivity provisions, if applicable, to confirm no competing business can operate within the same property or center. Should
Negotiate a tenant improvement (TI) allowance and document in the lease who owns any buildout improvements at lease end. Should

Physical Condition & Practical Inspection

Commission an independent commercial property inspection covering HVAC systems, electrical panels, plumbing, roof condition, and structural integrity. Must
Verify that the usable square footage matches the lease — confirm how the landlord measures space (usable vs. rentable) and what the load factor is. Must
Confirm internet, fiber, and telecommunications infrastructure availability and, if critical to operations, get service guarantees documented. Should
Walk the property at different times of day to assess foot traffic, neighborhood safety, neighboring tenants, and loading dock or delivery access. Nice to have

Personal Guarantees Carry Serious Financial Risk

Many commercial leases require the business owner to sign a personal guarantee, making you individually liable for rent obligations even if your business closes or fails. This can expose personal assets — including savings and property — to collection. Always have an attorney review the scope of any personal guarantee and negotiate for limits such as a 'good-guy' clause before signing. Never treat a personal guarantee as standard boilerplate to be accepted without scrutiny.

CAM Charges Can Grow Unexpectedly

Common Area Maintenance charges are frequently underestimated by first-time commercial tenants. Landlords may pass through costs for landscaping, security, management fees, and capital repairs with little notice. Always request a CAM reconciliation history and negotiate a cap on annual CAM increases — typically 3–5% — before finalizing the lease. Without a cap, your effective rent can climb substantially above the base rate over a multi-year term.
