Do You Have to Sign a Personal Guaranty on a Commercial Lease?

No law requires it, but most landlords leasing to a new or small business will ask, because the tenant entity has little credit history and the landlord is spending real money on build-out and commissions. A personal guaranty on a commercial lease makes you, the owner, liable for the tenant’s obligations if the LLC defaults, and an unlimited guaranty can run for the full term, every renewal, and every amendment. The question is not usually whether to sign but how much you are guaranteeing and for how long.

What an unlimited guaranty actually covers

The landlord’s form guaranty is a separate contract, and it is drafted to be broad. It typically covers all base rent, additional rent, damages, and the landlord’s attorneys’ fees, for the initial term and any renewal or extension, including amendments you may not have seen. It is usually “absolute and unconditional,” meaning the landlord can sue you without first pursuing the tenant, and it waives defenses the tenant might have. If there are several owners, each signs jointly and severally, so the landlord can collect the whole amount from any one of them. The guaranty survives an assignment of the lease unless it says otherwise, which means you can sell the business, hand the keys to a buyer, and remain liable for the buyer’s rent.

Read it as carefully as the lease. Our leasing practice often finds that the guaranty, not the lease, is the document that determines a founder’s real exposure.

The limited guaranties landlords will accept

A landlord that needs credit support will usually accept something narrower than the form. The common structures are:

• a capped guaranty, limited to a stated dollar amount or to a fixed number of months of rent;
• a rolling guaranty, under which you guarantee only the next several months of rent measured from the date of default, rather than the remaining term;
• a burn-off, under which the guaranty terminates or steps down after a set number of years of timely payment with no default;
• a guaranty that ends on a permitted assignment to a qualified buyer of the business, so that a sale actually releases you;
• a guaranty limited to the pre-surrender period, discussed below.

Spouses who are not involved in the business should not sign, and the guaranty should not reach jointly held assets unless you have agreed to that. If the landlord insists on an unlimited guaranty, the tenant improvement allowance and the free rent period should be larger to match the risk you are taking on.

The good guy guaranty, explained

New York practice developed the “good guy” guaranty, and it has spread elsewhere. Under it, the guarantor is liable for rent and other charges only through the date the tenant vacates and surrenders the premises, provided the tenant gives the agreed advance notice and is current on rent through the surrender date. A tenant whose business fails can leave, pay through the move-out, and walk away from the remaining term. The landlord gets back possession quickly and without litigation, which is why landlords accept it.

The details decide whether it works. The notice period should be realistic. The guaranty should state that the landlord accepts the surrender and that the guarantor’s liability ends on that date, not when the landlord relets. Watch for drafting that makes the guarantor liable for the landlord’s costs of reletting, brokerage, or unamortized improvements, which can reintroduce much of the exposure the clause was meant to remove. Remember too that a good guy guaranty protects the guarantor, not the tenant entity; the landlord can still pursue the LLC for the rest of the term.

Alternatives: deposits, letters of credit, and entity guaranties

Credit support does not have to be personal. A larger security deposit, a letter of credit from the tenant’s bank, prepaid rent for the final months, or a guaranty from a parent company can each substitute for or shrink the personal guaranty. A shorter initial term with renewal options also lowers the landlord’s exposure and gives you a reason to ask for a smaller guaranty. Which combination works depends on the landlord’s own lender, which often has a say in what credit the landlord must obtain. Our comparison of triple net and gross leases is relevant here, because in a net lease the guaranteed amount includes pass-through charges that rise over time, not just base rent.

Before you sign

Treat the guaranty as a negotiation item from the letter of intent onward, together with the other commercial lease terms worth negotiating. Confirm who is signing and in what capacity, whether the guaranty covers renewals and amendments, what law governs, and whether it contains a confession of judgment or a waiver of jury trial. Keep the entity separate in practice, since a guaranty is one thing and personal liability for the LLC’s debts is another; our business and corporate law group handles the entity side. And when the lease is amended years later, ask whether the guaranty needs to be re-signed; a guarantor who never agreed to the amendment may have a defense, and a landlord who forgets to ask has made a mistake you should not correct for free.
