A personal guarantee on a commercial lease makes you, the owner, personally liable for the lease if your business defaults, which puts your home and personal savings on the hook for rent the LLC cannot pay. The three structures that limit that exposure are the Good Guy Guarantee (liability ends when you surrender the space), the burn-off guarantee (the guaranteed amount shrinks each year of on-time payment), and a capped guarantee (liability limited to a fixed number of months). Never sign a full-recourse, full-term personal guarantee on a multi-year lease without trying for one of these first.
TL;DR
A personal guarantee pierces the liability protection of your LLC for this one contract. Landlords ask for it from small businesses and startups because the entity has no credit history or assets. Your job is to convert an unlimited, full-term guarantee into a limited one. The three tenant asks, in order: a Good Guy Guarantee (caps liability at the rent owed through the day you hand back the keys), a burn-off clause (the guarantee expires after 2 to 3 years of on-time payment), and a hard dollar cap (commonly 6 to 12 months of rent). Get the guarantee in a separate document so it can be released without amending the whole lease.
What a personal guarantee actually does
The lease is signed by your entity, usually an LLC or corporation. The personal guarantee is a separate promise, signed by you as an individual, that if the entity fails to pay, the landlord can collect from you personally.
That is the entire point of it from the landlord’s side. It defeats the reason most owners formed an LLC in the first place. If the business closes and the space sits empty, an unlimited guarantee can leave you owing every remaining month of rent out of your own pocket.
The exposure is real money. On a 5-year lease at $4,000 a month, an unlimited full-term guarantee is up to roughly $240,000 of personal liability before any concessions or mitigation. That is the number to shrink.
The four guarantee structures, worst to best for you
1. Full recourse, full term (worst)
You personally owe the entire remaining lease obligation on default, with no cap and no early exit. Avoid this on any term longer than one year.
2. Capped guarantee
Personal liability is limited to a fixed dollar amount or a set number of months, commonly 6 to 12 months of base rent. Once the landlord has collected that amount, your personal exposure ends even if more rent comes due. This is the most common compromise.
3. Burn-off (burn-down) guarantee
The guaranteed amount shrinks on a schedule, then disappears. A typical structure: full for year 1, reduced by a third in year 2, by two thirds in year 3, and released entirely after 36 months of on-time payment. The logic is fair: the longer you prove you pay, the less the landlord needs the backstop.
4. Good Guy Guarantee (best, and standard in many markets)
The Good Guy Guarantee (GGG) is widely used in New York City office and retail leases and increasingly elsewhere. Your personal liability is capped at the rent that accrues up to the day you vacate, surrender the keys, and leave the space in good condition, with proper notice. You stay liable for rent only while you occupy. Walk away cleanly and the personal exposure stops, even years before lease end. It does not erase the entity’s liability for the remaining term, but it protects you personally.
How to negotiate the guarantee down
The asks, in priority:
- Ask to remove it. Strong financials, a large security deposit, or prepaid rent can substitute. If your business has two years of profitable tax returns, lead with that.
- Convert to a Good Guy Guarantee. This is the highest-value single ask. It changes your personal risk from “the whole lease” to “rent until I leave.”
- Add a burn-off. Negotiate full release after 24 to 36 months of on-time payment.
- Cap it. If the landlord won’t burn it off, cap it at 6 to 12 months of base rent.
- Limit it to base rent. Exclude consequential damages, the landlord’s attorney fees, and unpaid CAM or NNN from the guaranteed amount where possible.
- Require notice and cure. The guarantee should only trigger after the entity has been given written notice and a chance to cure the default.
- Keep it in a separate document. A standalone guarantee can be released by a one-page letter once the burn-off condition is met, without reopening the lease.
A larger security deposit is the most common trade for a weaker guarantee. Model that cash cost in your total cost of occupancy before agreeing.
What a guarantee costs you in practice
The guarantee has no line-item price, but it carries real cost: it sits on your personal credit profile as a contingent liability, it can complicate a home refinance or a personal loan, and it is the single largest reason owners lose personal assets when a business fails. Treat it as a cost term, not boilerplate. The U.S. Small Business Administration’s leasing guidance flags personal guarantees as one of the highest-stakes terms a small-business tenant signs.
