Triple Net (NNN) Lease Explained for Texas Retail and Office Owners

A triple net (NNN) lease has the tenant paying base rent plus its share of three property costs: property taxes, building insurance, and common area maintenance (CAM). The owner receives those costs through monthly estimates, which are reconciled once a year. In Texas, NNN is the standard lease for retail strip centers and single-tenant buildings. It's less common in multi-tenant office buildings, where you'll typically see full-service or base-year rates.

Do you own a strip center in Garland or Mesquite? Then your tenants are almost certainly paying your property tax bill.

Well, sort of. You get paid, you pay the county, and once a year everyone checks the arithmetic. That's a triple net lease in one breath.

It sounds simple enough. In reality, NNN leases cause more owner/tenant disputes than almost anything else we come across. The majority of those disputes are actually kicked off by a vague lease or a poor reconciliation.

So let's go through how NNN actually works for Texas retail and office owners, with some real DFW numbers.

What Does NNN Lease Mean?

NNN is "net, net, net," with each "net" being one additional cost the tenant pays on top of the base rent.

• The first net is property taxes.
• The second is building insurance.
• The third is common area maintenance, or CAM.

CAM covers the common stuff. Parking lot repairs, landscaping, lighting, trash collection and occasionally a management fee.

The owner's rent is "net" of those expenses. In theory your income is stable regardless of what the costs go up to. In theory.

Single Net vs Double Net vs Triple Net vs Absolute NNN

"Net lease" is a broad family of lease types. The difference between them is in how many of the costs are passed to the tenant.

That final row is what appeals to the investor. One absolute NNN listing in DFW on Crexi actually had "zero landlord responsibilities" advertised. Very attractive if you can get it, though those leases usually go to national tenants with good credit.

Here's a trap. Brokers will sometimes say "NNN" when the actual lease is NN. Always check the repair section rather than the listing headline.

How a Triple Net Lease Works in a Texas Retail Strip Center

Each tenant pays its pro-rata share of the center's costs (i.e., on a per-square-foot basis).

Say you have a 20,000 sq ft strip center in the Dallas suburbs. A nail salon has 2,000 sq ft. Its pro rata is 10%.

Now let's say the center's annual NNN costs are $9 per square foot. Here's what that tenant would be paying in a given example year:

The $21.18 base rent is the DFW-wide retail NNN average per the Dallas Regional Chamber's 2026 retail data (from CoStar). The expense split is an example only. Actual centers will vary considerably.

How much do they vary? Look at the recent DFW listings. One Lancaster strip center is advertising CAM at $6.75 per square foot. A property on Henderson Avenue in Dallas has a 2026 NNN estimate of approximately $13.50.

That's a massive spread. The older centers with large parking areas and high tax values rank highest. The newer, more efficient centers rank lower.

Why Triple Net Leases Are Less Common in Texas Office Buildings

Multi-tenant office buildings in DFW will typically quote either full-service or "plus electric" rents with a base year. True NNN is more common in single-tenant offices, medical buildings, and smaller suburban properties.

Why the difference? Office buildings have so much in common. The lobbies, the elevators, the HVAC, the janitors and the security are all things which are extremely difficult to apportion fairly between dozens of tenants.

Retail is simpler, really. Each store has its own entrance, utilities, and usually its own HVAC. The only thing in common is the parking lot.

If you've got a small office building, then NNN can still work. Just anticipate more queries from your tenants and more detail in your reconciliation.

DFW Retail Rents and Occupancy in 2026

DFW retail is tight right now, giving owners the scope to be firm on NNN terms.

Weitzman reported 95.3% retail occupancy at mid-year 2026 (the same as the record DFW hit at the end of 2025). Bob Young at Weitzman called that record a "retail three-peat."

Rents vary sharply by area. Here's the Dallas Regional Chamber's 2026 snapshot, based on CoStar data:

Sources: Weitzman midyear 2026 report, Community Impact and the Dallas Regional Chamber.

One thing to watch is new supply. Weitzman forecasts around 4.2 million sq ft of new retail in 2026, up from 2.4 million in 2025. More space means tenants have more choice. Expect tougher negotiations on CAM caps in the growth corridors.

Why Texas Property Taxes and Insurance Make NNN So Popular

Texas has no state income tax. Property taxes are local, and commercial owners feel it.

Insurance is the other nightmare. Texas was the nation's hail damage capital for the 11th year in a row (according to United Policyholders). Hail claims in North Texas have devastated roofs, parking lots, and HVAC systems.

The bigger picture is actually worse. Mariam Yousuf of the Dallas Fed found that Texas went from 8 billion-dollar disasters in 2017 to 20 in 2024 (Dallas Fed).

Under a gross lease the landlord takes the increases. Under NNN, the tenant pays them. That's the whole point in one sentence.

It also explains why the tenants are so keen to protest. If their NNN charges go up 20% in a year they want to know why. You need to have a clean answer.

NNN Lease Pros and Cons for Texas Property Owners

NNN protects your income, but it adds work and can create tenant friction. That's the blunt truth of the trade-off.

That second row absolutely needs a highlighter. If 2,000 sq ft is vacant, then no one pays that 10% of the tax and insurance. You do.

CAM Reconciliation: The Part Most Owners Get Wrong

CAM reconciliation is the annual true-up. You compare what the tenants paid in estimates against what the property actually spent.

Here's how it usually runs:

1. Before the year starts, budget taxes, insurance, and CAM.
2. Bill each tenant a monthly estimate based on its pro-rata share.
3. After year-end, total the actual expenses.
4. Calculate each tenant's true share and any lease caps or exclusions.
5. Send a statement with backup, and either bill the shortfall or credit the overpayment.

Sounds easy, doesn't it? It isn't. Mostly because of step four.

Leases vary from tenant to tenant. One has a 5% cap on controllable CAM. Another doesn't include management fees. An anchor may pay a flat CAM. If you miss one of those clauses, that tenant's bill will be wrong.

Tenants notice. Many leases now include audit rights, and tenants are exercising them. A bad reconciliation can cost you the overcharge, the audit fee, and some goodwill you won't easily get back.

Our advice? Submit reconciliations on time, with the invoices attached. That level of transparency will resolve most disputes before they even get to the point of needing resolution.

NNN Lease Clauses Texas Owners Should Get Right

A good NNN lease answers the money questions before anyone asks them. These are the clauses that matter most:

• A clear definition of CAM, with what's included and what isn't
• How the pro-rata share is calculated, and whether vacant space is included
• Any cap on controllable expenses (tenants commonly ask for 3% to 5% a year)
• Whether management fees and administrative fees can pass through
• Who pays for roof and parking lot replacement versus repairs
• A deadline for sending the annual reconciliation
• Tenant audit rights, including how far back they can go
• How hail and storm deductibles get shared

That last one is more important in North Texas than almost anywhere else. A big hail deductible on a center's roof can be a five-figure shock. Who pays it is the question you have to answer while everyone is still on the same page.
