Personal Guarantee in a Commercial Lease: What It Means, What's at Stake, and How to Limit Your Exposure
You formed an LLC. You did everything right to protect your personal assets.
Then you signed a commercial lease with a personal guarantee — and the corporate shield you built became meaningless for that obligation.
Personal guarantees are one of the most significant clauses in any commercial lease, and one of the least understood. Most business owners sign them without knowing the full scope of what they've agreed to.
This post explains what a personal guarantee is, what it actually puts at risk, and what you can negotiate to limit your exposure before you sign.

What Is a Personal Guarantee?
A personal guarantee is a clause in a commercial lease that makes you — as an individual — personally responsible for the lease obligations if your business can’t fulfill them.
In plain terms: if your business defaults, closes, or can’t pay rent, the landlord can come after you personally. Your savings. Your home. Your personal bank accounts. Assets that have nothing to do with the business.
It’s how landlords protect themselves against the risk of leasing to a business entity that could dissolve. And it’s standard practice — especially for small businesses, newer companies, and any tenant without an established credit history as an entity.
The issue isn’t that guarantees exist. The issue is how they’re written.
Unlimited vs. Limited Guarantees
Not all personal guarantees are created equal. The most important distinction is whether yours is unlimited or limited.
An unlimited personal guarantee makes you personally liable for every dollar owed under the lease — all remaining rent, CAM charges, property taxes, legal fees, and any other obligations — for the full remaining term. If you have three years left on a $6,000/month lease and your business closes, that’s potentially $216,000 in personal exposure.
A limited personal guarantee caps your liability. Common structures include:
Capped by months — e.g., limited to 12 months of base rent
Capped by dollar amount — e.g., limited to $50,000 regardless of remaining term
Capped by time — e.g., guarantee burns off after 24 months of on-time payments
Capped by event — e.g., guarantee only triggers on specific default events, not general financial distress
The difference between unlimited and limited can be the difference between a recoverable business setback and a personal financial crisis. Most landlords start with unlimited. Most tenants don’t know to push back.
What Else Might Be in Your Guarantee Clause
Beyond the core unlimited vs. limited question, there are several additional provisions that can significantly expand your exposure:
Spousal signature requirements. Some landlords require a spouse or domestic partner to co-sign the guarantee, extending the liability into your household. This is negotiable — and should be removed if at all possible.
Rent acceleration. If your lease includes a rent acceleration clause, a default can trigger the entire remaining balance of rent becoming due immediately. Combined with an unlimited guarantee, this can create overnight catastrophic personal liability.
Survival after assignment or sale. In some leases, the personal guarantee survives even if you sell the business or assign the lease to a new tenant. You’re gone, but you’re still on the hook.
No cure period. Without a defined cure period, a landlord can trigger the guarantee without giving you time to fix a default. A missed payment becomes a personal liability event instantly.
Search your lease for the words ‘guaranty,’ ‘guarantee,’ and ‘personally liable.’ Those three searches will tell you exactly where your exposure starts.
How to Negotiate Your Personal Guarantee
Landlords expect pushback on guarantees. Here’s what to ask for:
Cap the guarantee by months — 12 months of base rent is a reasonable starting position for most tenants
Burn-down provision — the guarantee reduces over time as you demonstrate payment history
Remove spousal signature requirement
Define and limit the trigger events — guarantee should only activate on specific defaults, not general financial hardship
Add a cure period — at minimum 10 business days written notice before the guarantee can be enforced
Negotiate survival language — ensure the guarantee terminates upon a legitimate assignment or business sale
Some landlords will push back. But many will negotiate — especially if you have good credit, a strong business profile, or if the market is competitive. The guarantee is a risk-management tool for the landlord. If you can demonstrate low risk another way, the negotiation becomes easier.
What Happens If You Don’t Negotiate
A business owner signs a 5-year NNN lease with an unlimited personal guarantee. Two years in, the business struggles. Revenue drops. They close the location.
The landlord doesn’t just re-lease the space and move on. They pursue the guarantee holder for the remaining 36 months of rent — plus CAM charges, legal fees, and accelerated rent triggered by the default clause.
The LLC is gone. But the individual is still liable. Personally. For everything.
This is not a hypothetical. It’s one of the most common financial consequences we see in commercial lease disputes — and almost entirely preventable with the right language negotiated before signing.
The Bottom Line
A personal guarantee in a commercial lease is not a formality. It’s a direct connection between your business obligations and your personal financial life.
Understanding the scope of your guarantee — and negotiating limits before you sign — is one of the highest-value things you can do in any commercial lease transaction.
