The one-sentence version
A good guy clause is a limited personal guarantee. You stay personally responsible for rent and other charges up to the day you actually hand the space back, and only that far. Return it empty, clean, and current on everything, after giving the landlord the advance written notice the clause requires, and your personal exposure stops there. The rent that would have come due over the remaining years is not yours personally. That is the entire trade.
It sits between the two positions most tenants think are the only ones on the table. A full personal guarantee puts everything you own behind every dollar of a ten-year lease. No guarantee at all is something very few South Florida landlords will hand a small business with two years of operating history. The good guy structure gives the landlord the thing they actually care about, which is a tenant who leaves properly instead of one who stops paying, stops answering the phone, and leaves behind a half-finished build-out and a padlock. I wrote separately about negotiating a personal guaranty down. This is about the specific structure tenants now ask for by name, usually without knowing what it actually covers.
What it does not do
Here is the misunderstanding I run into constantly, and it is an expensive one.
A good guy clause does not terminate your lease. It does not release your company. It limits your personal liability and nothing else.
Walk through a hypothetical, and treat it as nothing more than that. Your LLC signs a five-year lease and you sign a good guy guaranty. Two years in, the business is not working. You give the required notice, pay everything owed through the surrender date, hand back a clean and empty space, and go. Your personal liability ends. Your LLC's liability does not. The landlord can still pursue the entity for the three remaining years of rent. Whether that is worth chasing depends on whether the entity has anything left, which for a failing small business is often nothing, and that is precisely why the structure works in practice. But if the company still holds equipment, a liquor license, receivables, or cash you were planning to take out as a distribution, the entity's remaining exposure is not academic.
Worth saying plainly here: I am a broker, not an attorney. I negotiate this term in letters of intent for a living and I read the resulting language on every deal, but a guaranty is a separate contract with real consequences, and a Florida real estate attorney should review the actual words before you sign them.
The four conditions the whole thing turns on
Every good guy clause I have read is conditional. Fail one condition and the limitation does not apply, which puts you back under a full guarantee at the worst possible moment. Four conditions show up almost every time.
- Advance written notice. Usually somewhere between 60 and 180 days before the surrender date, delivered exactly the way the lease notice provision requires. A text to your leasing contact is not notice. Certified mail to the address in the lease usually is.
- Actual surrender of possession. Vacant, broom-clean, free of subtenants and any other occupant, keys delivered. If a subtenant is still in there, or your walk-in cooler is still in there, you have not surrendered.
- Everything paid through the surrender date. Not just base rent. That distinction is the next section, because it is where the number gets bigger than people expect.
- No uncured default. Many drafts require that you not be in default when you give notice and not be in default when you surrender. A tenant who is already three weeks late when the decision finally gets made may have lost the protection before using it.
Read the words "all sums due," not just "rent"
Most good guy language covers base rent plus additional rent. In a triple net lease, additional rent is your share of taxes, insurance, and common area maintenance, and those are usually billed as monthly estimates and reconciled after the calendar year closes. So a September surrender can produce a reconciliation bill the following March covering the months you occupied. Drafted well, that is bounded and you can see it coming. Drafted the landlord's way, your personal guarantee stays open until every reconciliation for every period of occupancy is settled, which can be a year after you are gone. If net leases are new to you, read how triple net actually works for Florida tenants first. You cannot evaluate this clause without knowing what sits inside "additional rent."
What I ask for: an outside date after which no further claim can be made against the guarantor, commonly 90 to 180 days after surrender, with the final-year reconciliation left as an obligation of the tenant entity.
The clawback that quietly eats the clause
Separate from the guaranty, many leases recapture unamortized costs on an early termination. That means the tenant improvement allowance the landlord funded, the free rent months it gave you, and sometimes the brokerage commissions it paid. On early surrender, the unamortized balance becomes due immediately.
Here is the trap. That obligation usually lives in the lease, not in the guaranty, and good guy language often releases the guarantor from obligations accruing after the surrender date. The clawback arguably accrues on the surrender date. I have read drafts where it is genuinely unclear, and unclear favors the party who wrote it. If you fix nothing else in this clause, get an express sentence saying whether the guarantor is liable for unamortized TI and abated rent. On a build-out heavy deal that figure can exceed a year of rent.
Where the negotiation actually happens
Landlords who accept the concept still fight over four things:
- The notice period. The landlord wants twelve months so it can re-tenant with no gap. You want ninety days. This is the real bargaining chip, because every month of notice is a month of rent you are personally guaranteeing. A 180-day notice period on a space at $12,000 a month is $72,000 of personal exposure you agreed to without noticing.
- A floor before you can use it. Some landlords accept the structure only with a minimum, such as no notice before the end of month 24. That is often reasonable, and it is worth trading for a shorter notice period.
- Condition at surrender. Push for broom-clean, ordinary wear and tear excepted, with no obligation to remove any improvement the landlord approved. Otherwise a restoration demand becomes the argument that you failed the surrender condition.
- Who signs. If you are married, the guaranty should name you and not your spouse. Florida is not a community property state and there is often room to keep an uninvolved spouse off the document. Ask your attorney how to do that correctly.
All of this belongs in the letter of intent, not in the lease redline. Once an LOI says "personal guaranty of the full term," the landlord's attorney drafts exactly that, and asking three weeks later to convert it into a good guy structure reads as retrading a closed point. The LOI is where guaranty structure gets decided, every time.
Can you actually get one in South Florida?
In my experience the term comes out of the New York market, where it is standard. Down here it is not on most landlord forms, and plenty of landlord's counsel will tell you flatly that they do not do those. What they mean is that it is not on their form. The concept is negotiable, and the fastest path is often to drop the phrase entirely. Ask instead for a guarantee capped at all sums due through the date of surrender, with a defined notice period and defined surrender conditions. Same economics, no argument about a term of art borrowed from another market.
Who you are asking matters more than what you call it. The buildings small tenants occupy here are mostly owned by individuals and small partnerships rather than institutions. Across 778 recorded office transfers in Miami-Dade from 2021 through 2026, the median building that changed hands was 1,734 square feet at $438 per square foot, roughly $825,000. That is not a REIT's asset. That is somebody's building, and an owner with one building can decide on a guaranty structure in an afternoon. Institutional landlords have a written guaranty policy and an approval chain, so budget weeks and expect a burn-down rather than a clean good guy cap.
The mistakes I see tenants make
- Treating the clause as a termination right. It is not one. The entity still owes the balance of the term.
- Giving notice before actually being ready to move, then missing the stated surrender date and losing the protection.
- Leaving a subtenant, a sign, or a room of equipment behind and assuming close enough counts as surrender.
- Winning the clause at signing, then quietly reinstating a full-term guarantee in a renewal amendment years later. Every extension reopens the guaranty, and most tenants sign the amendment without rereading it.
- Never reading the notice provision until the day they need it, then serving notice by email to a leasing agent who left the company.
What I would ask for
On a five-year deal for a small business tenant in Broward, Miami-Dade, or Palm Beach, the package I push for is this: liability limited to all sums due through the date of surrender, a 90 to 120 day notice period, no notice permitted before the end of month 18, broom-clean condition with no restoration obligation, an express carve-out of unamortized TI and abated rent from the guarantor's liability, and a 120-day outside date for any further claim after surrender. Not every landlord gives all of it. Most give some of it. The ones who give none of it are telling you something useful about how the rest of the relationship is going to go.
If you are sitting on an LOI right now with a full-term guarantee in it, this is the moment it is fixable and the only moment it is cheap. My tenant representation is paid out of the landlord's commission budget, so having someone read the guaranty before you sign it costs you nothing.
Frequently Asked Questions
What is a good guy clause in a commercial lease?
It is a limited personal guarantee. The guarantor is personally liable for rent and other charges only through the date the tenant actually surrenders the space, rather than for the full remaining term. It applies only if the tenant gives the required advance written notice, returns the space vacant and broom-clean, and is current on everything owed as of that date.
Does a good guy clause let me cancel my lease early?
No, and this is the most common misreading. The clause limits the individual guarantor's exposure. It does not terminate the lease or release the tenant entity, which remains liable for the rent that would have come due over the balance of the term. If the company still holds assets, that remaining liability is real. A Florida attorney should walk you through what your entity is exposed to.
How much notice does a good guy clause usually require?
Typically 60 to 180 days of advance written notice, though landlords often open at twelve months. The notice period is the number to negotiate hardest, because every month of notice is another month of rent you are personally guaranteeing. On a space at $12,000 a month, cutting notice from 180 days to 90 days removes roughly $36,000 of personal exposure.
Are good guy clauses common in South Florida?
They are far more common in New York than here, and most South Florida landlord forms do not include one. The structure is still negotiable. It is often easier to ask for a guarantee capped at all sums due through the surrender date, with defined notice and surrender conditions, rather than using the New York term of art and arguing about what it means.
Does a good guy clause cover CAM and tax reconciliations?
It depends entirely on drafting. Most cover base rent plus additional rent, which in a triple net lease includes your share of taxes, insurance, and common area maintenance. Because those are reconciled after the year closes, a claim can arrive months after you leave. Ask for an outside date, commonly 90 to 180 days after surrender, after which no further claim reaches the guarantor.
Can the landlord still claw back tenant improvement money?
Often yes. Many leases recapture unamortized tenant improvement allowance, abated rent, and sometimes commissions on early termination. That obligation usually sits in the lease rather than the guaranty, and drafting is frequently ambiguous about whether the guarantor is covered. Get an express sentence either way. On a build-out heavy deal the clawback can be larger than a year of rent.
When should I negotiate the guaranty structure?
At the letter of intent stage. Once an LOI specifies a personal guaranty of the full term, the landlord's counsel drafts exactly that, and reopening it during lease review is treated as retrading. Guaranty structure, notice period, and surrender conditions all belong in the LOI alongside rent, term, and tenant improvement allowance.
