NNN vs Gross Lease: What Jacksonville Commercial Tenants Need to Know Before Signing

Before you sign a commercial lease in Jacksonville, you need to understand one fundamental distinction: NNN (triple net) vs gross. This single clause determines what you actually pay each month — and the difference between the two can mean thousands of dollars a year in unexpected costs.

What Is a Gross Lease?

In a gross lease (sometimes called a full-service lease), the landlord covers property taxes, insurance, and common area maintenance (CAM). You pay one flat monthly amount, and that's it — predictable, simple, and common in office space, especially Class A suburban buildings.

Pros:

• Predictable monthly cost — no surprise CAM bills.
• Simple budgeting.
• Landlord handles maintenance and repairs.

Cons:

• Higher base rent than a comparable NNN lease.
• Less control over how the building is maintained.
• Annual increases are baked into the base rent.

What Is a NNN (Triple Net) Lease?

In a NNN lease, you pay base rent plus your share of property taxes, insurance, and CAM. These additional costs are typically estimated monthly and reconciled annually. NNN is the dominant structure for retail, industrial, and restaurant space in Jacksonville.

Pros:

• Lower base rent than a gross lease.
• You see exactly what the building costs to operate.
• More transparency on expenses.

Cons:

• Monthly cost fluctuates as taxes and CAM change.
• CAM reconciliation trap (see below).
• More risk shifted to the tenant.

The CAM Reconciliation Trap

Here's the scenario that catches Jacksonville tenants off guard every year:

The landlord estimates your CAM charges monthly — say, $1,000/month on a 2,000 SF retail space. You pay that all year. Then at year-end, the landlord reconciles actual expenses. If actual CAM came in at $1,500/month, you owe the difference — $6,000 in a single bill.

This happens most often in the first year of a lease (when estimates are based on guesswork) and in years when property taxes spike (Jacksonville's tax reassessments can move this number significantly).

How to protect yourself:

• Ask for the prior year's actual CAM charges before signing — not the estimate.
• Negotiate a CAM cap (see below).
• Build a 15–20% contingency into your budget for reconciliation bills.

What to Negotiate in a NNN Lease

A NNN lease is not take-it-or-leave-it. Here's what a commercial broker should negotiate for you:

1. CAM cap (3–5%): Limits how much CAM can increase year-over-year, protecting you from runaway expenses.
2. Exclude capital expenditures from CAM: Roof replacements, HVAC, and parking lot repaving should not be passed through to tenants — they're the landlord's responsibility.
3. Audit rights: You should have the right to review the landlord's actual CAM expenses annually, typically within 60–90 days of receiving the reconciliation.
4. Right to contest tax assessments: If the landlord's tax bill goes up because they didn't contest an assessment, that shouldn't be your problem.
5. Base year for expenses: In a modified gross lease, expenses above a base year are passed through — make sure the base year is a normal expense year, not an artificially low one.

A Real Cost Comparison

Take a 2,000 SF retail space in Jacksonville, quoted two ways:

| Structure | Base Rent | NNN/CAM | Total | Annual Cost | Monthly | |---|---|---|---|---|---| | NNN lease | $18/SF | $6/SF | $24/SF | $48,000 | $4,000 | | Gross lease | $24/SF | — | $24/SF | $48,000 | $4,000 |

On paper, these look identical. But over a 5-year term, the NNN lease carries risk of annual increases — if CAM rises 5% per year, your total cost climbs, while the gross lease stays flat (subject only to fixed annual base rent bumps). The gross lease is more predictable; the NNN lease is potentially cheaper in year one but riskier over time.

Which Lease Type Is Right for You?

• First-time tenants and service businesses → Gross lease. Predictability matters more than squeezing out $1/SF.
• Retail and restaurant tenants → NNN is the market standard in Jacksonville; you'll rarely have a choice, so focus on negotiating CAM caps and exclusions.
• Established tenants with strong financials → NNN with negotiated protections can be cost-effective, especially on longer terms.
• Industrial and warehouse tenants → NNN is standard; negotiate hard on capital expenditure exclusions.

Before You Sign

Before signing any NNN commercial lease in Florida:

1. Ask for the prior year's actual CAM charges.
2. Negotiate a CAM cap (3–5%).
3. Ensure capital expenditures are excluded from CAM.
4. Secure audit rights.
5. Have a commercial broker review the lease and confirm your total occupancy cost.
