When you sign a commercial lease through your LLC or corporation, you might think your personal assets are protected by the corporate veil. Then the landlord slides a personal guarantee across the table. Suddenly, your house, savings, and personal credit are on the line for a 5-year lease obligation that could total hundreds of thousands of dollars. Personal guarantees are standard in commercial leasing, especially for small businesses and startups without established credit histories. But the terms of these guarantees vary enormously — and most tenants sign them without negotiation.
What is a Personal Guarantee?
A personal guarantee is a legally binding commitment by an individual (typically the business owner or principal) to be personally liable for the obligations of their business entity under a commercial lease. If the business defaults on rent, the landlord can pursue the guarantor's personal assets — bank accounts, real estate, investments, and wages — to recover the debt. The guarantee typically covers the full remaining lease obligation, not just unpaid rent, and may include future rent acceleration, legal fees, and property damage.
Red flags to watch for
A guarantee covering the entire lease term (often 5–10 years) with no burndown provision means your personal exposure stays at maximum even as you prove yourself a reliable tenant.
If you assign your lease to a new tenant but the guarantee continues, you remain personally liable for someone else's obligations. This defeats the purpose of assignment.
Combined with a personal guarantee, an acceleration clause means a single default could make you personally liable for years of future rent in one lump sum.
Some guarantees extend beyond rent to include the cost of restoring the premises to original condition, which can add tens of thousands to your personal exposure.
Landlord's attorney fees for enforcement can be substantial. Without a cap, these costs are added to your personal liability on top of the rent owed.
Your legal rights
Personal guarantees in commercial leases are governed by state contract law and are generally enforceable as written. Unlike consumer contracts, commercial leases have limited statutory protections. However, the UCC (Article 9 for secured transactions) and state-specific laws may apply to certain aspects. Under the common law, a guarantee must be in writing to be enforceable (Statute of Frauds). Some states limit deficiency judgments or require landlords to mitigate damages — for example, under New York Real Property Law §235-f and case law requiring mitigation. In California, Civil Code §1951.2 requires landlords to make reasonable efforts to re-let the space, which can reduce your guarantee exposure. The CARES Act and subsequent legislation provided temporary protections for commercial tenants during COVID-19 but these have largely expired.
Questions to ask before you sign
- 1Can the personal guarantee be limited to a specific dollar amount or time period rather than the full lease term?
- 2Is there a burndown provision that reduces my guarantee exposure over time as I establish a payment history?
- 3Does the guarantee terminate if I assign the lease to a qualified replacement tenant?
- 4Does the landlord have a duty to mitigate damages before pursuing me personally?
- 5Can I negotiate a 'good guy guarantee' where my liability ends when I vacate and surrender the space?
- 6Are legal fees and collection costs under the guarantee capped at a reasonable amount?
