If you’re shopping for office, retail, or industrial space in Rockwall or anywhere across the greater DFW area, you’ll run into lease terms like “NNN,” “gross,” and “modified gross” almost right away. They sound like jargon, but they decide who pays for what over the life of your lease. Getting clear on them early makes it a lot easier to compare spaces side by side and avoid surprises after you move in.
Here’s a plain-English breakdown of how each lease type works and what to ask before you sign.
What Is a Triple Net Lease?
A triple net lease, often written as an NNN lease, is a lease where the tenant pays base rent plus their share of the property’s three main operating costs:
- Property taxes on the building and land
- Building insurance carried by the owner
- Common area maintenance (CAM), which covers things like landscaping, parking lot upkeep, exterior lighting, and shared repairs
Those three are the “nets.” In a multi-tenant building, each tenant usually pays a share based on how much of the building they occupy. The owner estimates the year’s costs, tenants pay monthly toward that estimate, and there’s a reconciliation at year end.
Triple net leases are especially common for retail centers, freestanding restaurant buildings, medical offices, and single-tenant properties. They’re popular with investors because the operating costs pass through to the tenant, which makes the income more predictable.
What Is a Gross Lease?
With a full service gross lease, the tenant pays one rent amount and the landlord covers the building’s operating expenses out of that. Taxes, insurance, and maintenance are baked in. You’ll see this most often in multi-tenant office buildings.
The upside for tenants is simplicity. Your occupancy cost is easier to budget because it doesn’t move around as much when taxes or insurance change. The trade-off is that the landlord builds those expected costs into the rent from the start.
What About a Modified Gross Lease?
A modified gross lease lands in between. The tenant and landlord split the operating costs in whatever way they negotiate. A common setup is the landlord covering taxes and insurance while the tenant handles their own utilities and janitorial. Another is a “base year” structure, where the tenant only pays increases in operating costs above the first year’s level.
Because there’s no single standard, modified gross leases are where reading the fine print matters most.
Triple Net Lease vs Gross Lease: A Quick Comparison
| Lease Type | Tenant Pays | Landlord Pays | Common For |
|---|---|---|---|
| Triple Net (NNN) | Base rent plus share of taxes, insurance, and CAM | Usually roof and structure, depending on the lease | Retail, restaurants, medical, single-tenant buildings |
| Modified Gross | Base rent plus negotiated items | Negotiated items | Office, flex, smaller multi-tenant buildings |
| Full Service Gross | One rent amount | Taxes, insurance, maintenance, often utilities | Multi-tenant office buildings |
Which Lease Type Is Better for Your Business?
Neither one is automatically better. It depends on your business, the property, and how much predictability you want. A few things worth thinking through:
- How much does budget certainty matter? If you want a steady monthly number, a gross lease is easier to plan around.
- How long will you stay? On a longer term, operating costs can shift over time, so it pays to understand how increases are handled.
- What kind of space do you need? If you’re after a retail storefront or a freestanding building, you’ll likely be looking at NNN leases no matter what.
- Who handles repairs? Some leases put HVAC, roof, or parking lot repairs on the tenant. Others don’t. That can matter as much as the rent itself.
Questions to Ask Before You Sign
- What are the current estimated operating expenses, and what did they look like the past few years?
- Is there a cap on how much CAM charges can increase each year?
- What’s included in CAM, and what’s excluded?
- Who is responsible for HVAC, roof, and structural repairs?
- How and when are year-end reconciliations handled?
- Do I have the right to audit operating expense charges?
These are the kinds of details a good commercial real estate broker will dig into on your behalf. When you have your own representation, someone is comparing lease structures across properties and pushing for terms that fit your business, not just the landlord’s.

Frequently Asked Questions
What does NNN mean in a commercial lease?
NNN stands for triple net. It means the tenant pays base rent plus their share of the property’s taxes, insurance, and common area maintenance.
Is a triple net lease good for tenants?
It can be. Triple net leases often come with lower base rent, and tenants see exactly what operating costs they’re paying for. The trade-off is less predictability, since those costs can change year to year.
What is the difference between a gross lease and a net lease?
In a gross lease, the landlord pays the building’s operating costs out of one rent amount. In a net lease, the tenant pays some or all of those costs on top of base rent.
What is CAM in a commercial lease?
CAM stands for common area maintenance. It covers the upkeep of shared areas like parking lots, landscaping, lighting, and common hallways, split among tenants in the building.
