Understanding Commercial Leases: Gross vs. NNN, Options & Common Pitfalls
Commercial leases aren’t just about the monthly rent—your total occupancy cost and the fine print can make a big difference over time. Here’s a quick guide to the basics:
GROSS vs. NNN (Triple Net)
Gross Lease: You pay a base rent, and the landlord typically covers most building operating costs (taxes, insurance, CAM).
NNN Lease: You pay base rent plus your share of taxes, insurance, and common area maintenance (CAM)—so the “rent” you see is not the full monthly cost.
Tip: Always ask for an estimate of NNN/CAM charges and expense history so you know the true monthly number.
OPTIONS (Flexibility that matters)
Look closely at:
Renewal options (and the notice deadlines—missing them can cost you)
How rent is set during renewals (fixed increases vs. “market rent”)
Assignment/sublease rights if you sell the business or need to sublet
Use clause (make sure it’s broad enough for your business to evolve)
Common pitfalls we see:
Focusing only on base rent, not total costs (NNN/CAM/utilities)
Unclear responsibility for HVAC, roof, and major repairs
Vague CAM definitions (what’s included and what’s not)
Signage, parking, or access terms that limit operations
Personal guarantees that are broader than expected
Quick checklist before you sign
Can you clearly answer:
What is my all-in monthly cost?
Who pays for big-ticket repairs?
How do rent increases work?
What are my renewal/extension options?
Can I assign the lease if I sell my business?
