How much does a commercial lease review cost?

The cost of reviewing a commercial lease depends almost entirely on who does it. There are three realistic options: a real estate attorney, an AI-powered lease analysis tool, or a DIY approach using a general-purpose AI chatbot. Each has a different price point, turnaround time, and output format.

A commercial lease is usually a multi-year commitment, and often a personal one if you sign a guarantee. The question is not whether to review it, but which method fits your situation.

Attorney review: what you get and what you pay

A real estate attorney review is the gold standard. The attorney reads the full lease, flags unfavorable clauses, explains your legal exposure, suggests negotiation positions, and can represent you directly with the landlord's counsel. For high-stakes leases — flagship retail locations, long-term office space, sale-leaseback transactions — this is often the right choice.

What attorneys charge per hour

At those rates, a standard commercial lease review costs roughly $1,100–$1,900 in attorney time. Negotiating with the landlord's attorney adds more hours on top.

What you get: a written memo identifying risk clauses, recommended redlines, and legal advice you can act on. What you do not get: speed. Attorney availability, scheduling, and back-and-forth typically mean 2–5 business days minimum before you have anything in hand.

AI lease analysis: how it works

AI-powered lease analysis tools like LeaseLens (leaselens.org) take a different approach. You upload your lease PDF, pay a flat fee, and receive an emailed review of 22 lease terms — a verdict, answers to your questions, the changes to make ranked by dollars at stake with contract-ready replacement language and a fallback, a separate “Requested lease changes” PDF to send the landlord, contradictions inside the lease, and rent and key dates — usually 2–3 minutes (up to 5 for very long leases).

LeaseLens charges $75 per report, paid once. The output is a structured, shareable review, not a chat response. Every lease is checked against the same 22-term checklist with market benchmarks drawn from published commercial real estate attorney guidance, and checks every quote word-for-word against your lease — so nothing on the checklist gets missed because you forgot to ask about it.

What AI analysis does not provide: legal advice. LeaseLens reports are informational — they tell you what the lease says and flag what is unusual, but they do not constitute legal counsel and do not create an attorney-client relationship. For many tenants, the right workflow is to run a LeaseLens analysis first, then bring the flagged clauses to an attorney for a focused (and therefore cheaper) legal review.

Side-by-side comparison: Attorney vs. LeaseLens vs. DIY ChatGPT

The key difference between LeaseLens and a DIY chatbot is not the underlying AI, it is structure. A general-purpose AI chatbot responds to your questions. LeaseLens applies a fixed checklist to every lease, so you get a complete analysis even when you do not know what to ask for. It checks every quote against your lease and benchmarks each term against market. It also produces a requested-changes PDF you can send to your landlord, and a review you can share with your attorney or business partner.

When to use which option

The right choice depends on the complexity of your lease, the length of the term, and how much time pressure you are under.

You can also use both: run a LeaseLens analysis at $75 to find the highest-risk clauses, then bring that list to an attorney for a focused session instead of starting from scratch. LeaseLens is a fast, plain-English first read that tells you what to change; it makes attorney time cheaper and more focused, not unnecessary.

Reviewing a lease without an attorney

Most small-business tenants don't have a real estate attorney on call. You can still get a solid first read on your own, because the expensive terms sit in a handful of provisions. These are the ones most worth understanding before you sign:

• CAM charges. Common area fees are often uncapped and defined broadly. “Operating expenses” can quietly include landlord overhead, management fees and capital improvements.
• Personal guarantee. You sign personally, not just as a business. Know whether it covers the full term, whether it burns off over time, and whether it survives a sale of the business.
• Holdover rent. Stay past the end date without a new agreement and many leases charge 150–200% of base rent.
• Rent increases. Fixed percentage, CPI-linked or stepped, and whether they compound. At 3% a year, year-10 rent is about 30% higher than year 1.
• Renewal options. Whether you can renew, how renewal rent is set (fair market or fixed), and the notice deadline. Many options require notice 6 months or more before the lease ends.
• Relocation. Whether the landlord can move you to another space in the property, and on what notice and compensation.

What “standard lease” means: when a landlord calls a lease standard, it means standard from the landlord's attorney's side. A “standard” lease can still have uncapped CAM, a full personal guarantee, a 150% holdover rate and no real renewal option. All of those are negotiable.

What a good commercial lease review should cover

Whether you use an attorney or an AI tool, a complete commercial lease review should address all of the following. If your review does not cover these, you have gaps.

LeaseLens checks 22 lease terms on every lease, covering most of these — rent increases, CAM, personal guarantee, renewal options, early termination, holdover, assignment and subletting, build-out allowance, insurance, and exclusive use — plus lender protection (SNDA), relocation, landlord liens, default remedies, co-tenancy, required operating hours and more. Permitted use and casualty provisions are not separate checklist items, so give those a careful read yourself or with an attorney.
