The Verdict
Hire the attorney. A $3,000 review fee is cheap insurance against a $150,000 mistake. The question is never the attorney cost — it is the cost of the clause you did not understand.
When this flips: Short-term residential leases under 12 months in tenant-friendly states are lower risk for DIY review. A 10-year commercial lease with a personal guaranty is never DIY territory.
Frequently Asked Questions
- How much does a commercial lease attorney typically cost?
- Commercial lease review and negotiation typically runs $1,500-$5,000 depending on the attorney, market, and complexity of the lease. A straightforward 3-year office lease runs less than a 15-year restaurant lease with NNN and personal guaranty.
- What does a lease attorney actually do?
- They read every clause, flag obligations you have not noticed, identify one-sided language, and negotiate specific changes with landlord counsel. They are not just reviewing for comprehension — they are identifying leverage points.
- What is the most common clause that DIY reviewers miss?
- The restoration clause — which requires you to restore the space to its original condition at your expense when you leave. On a buildout-heavy space, this exposure runs $20,000-$100,000.
- Do residential tenants need an attorney to review their lease?
- Not always. Short-term residential leases in states with strong tenant protection laws are generally manageable without counsel. Multi-year leases in landlord-favorable states with large security deposits or unusual clauses warrant a review.
- Can I negotiate my own commercial lease without an attorney?
- You can, but you are negotiating against a landlord whose attorney wrote the lease specifically to favor the landlord. You do not know what you do not know — and the restoration clause on page 14 is what gets most tenants.
