Understanding Office Lease Types in Omaha
Market data as of Q1 2026
The lease type on your office space determines far more than your monthly check. It defines which operating expenses you pay, how predictable your costs are year to year, and how easy it is to compare one building against another. Understanding the three main lease structures used in the Omaha market -- triple net (NNN), full-service, and modified gross -- is essential before signing any commercial lease.
Two buildings quoting $22/sf and $28/sf may actually cost the same once you account for lease structure. The difference is who pays the operating expenses and how they are allocated. This guide breaks down each type so you can compare office space pricing accurately.
Triple Net (NNN) Leases
In a triple net lease, the tenant pays base rent plus three categories of operating expenses separately: property taxes, building insurance, and common area maintenance (CAM). This is the most common structure for Class A office space in Omaha, particularly in suburban corridors like West Omaha.
The advantage of NNN is transparency. You see exactly what the building costs to operate, and you benefit if the landlord keeps expenses low. The downside is cost variability -- property taxes can increase after reassessment, insurance rates fluctuate, and CAM costs may rise with aging building systems.
Typical NNN Cost Breakdown in Omaha
| Expense Category | Typical Range ($/SF/Year) | What It Covers |
|---|---|---|
| Base Rent | $22-30/sf (Class A) | Your occupancy right to the space |
| Property Taxes | $2.50-4.00/sf | Real estate taxes assessed by county |
| Insurance | $0.50-1.00/sf | Building liability and property coverage |
| CAM | $3.00-5.00/sf | Maintenance, landscaping, snow removal, management fees |
| Total Occupancy | $28-40/sf (Class A) | Your actual cost to occupy the space |
When evaluating a NNN lease, always ask for the building's current operating expense statement and at least three years of expense history. This tells you how costs have trended and whether the landlord manages expenses efficiently.
Full-Service (Gross) Leases
A full-service lease bundles base rent and all standard operating expenses into a single quoted rate. The landlord pays property taxes, insurance, and CAM from the gross rent collected. This structure is more common in downtown Omaha office buildings, particularly multi-tenant towers where simplifying expense allocation makes sense.
The primary advantage is budget predictability. You pay one number each month and the landlord absorbs operating expense fluctuations. This simplicity is especially valuable for smaller tenants or businesses new to commercial leasing.
The trade-off is less transparency. You do not see how the landlord allocates your rent to expenses, and you may be paying a premium for the convenience. Full-service leases may also include "expense stop" or "base year" provisions that shift costs back to you after the first year if operating expenses increase.
Watch for base year clauses: Many full-service leases set a "base year" of operating expenses (usually your first lease year). If expenses increase above that baseline in future years, you pay the difference. This means a full-service lease can start to feel like a NNN lease over time. Ask what the base year expenses are and how they have increased historically.
Modified Gross Leases
A modified gross lease is a hybrid between NNN and full-service. The landlord includes some operating expenses in the base rent and passes others through to the tenant. There is no standard formula -- each modified gross lease defines its own split of expenses, which makes it critical to read the lease terms carefully.
Common arrangements in the Omaha market include the landlord covering insurance and property taxes while the tenant pays CAM and utilities, or the landlord covering all expenses except janitorial and utility costs for the tenant's suite.
Modified gross leases are common in Class B and Class C buildings where landlords want to offer a simpler alternative to NNN without absorbing all expenses. They offer a middle ground: more predictable than NNN, more transparent than full-service.
Lease Type Comparison
This side-by-side comparison summarizes the key differences between the three lease structures you will encounter in the Omaha office market:
| Lease Type | Base Rent | Additional Costs | Best For | Common In |
|---|---|---|---|---|
| Triple Net (NNN) | Lowest quoted rate | Taxes + Insurance + CAM ($6-10/sf) | Tenants who want transparency | Class A suburban |
| Full-Service | Highest quoted rate | Included (with possible base year escalations) | Tenants who want simplicity | Downtown multi-tenant |
| Modified Gross | Mid-range quoted rate | Some expenses included, some passed through | Tenants who want a hybrid | Class B and C buildings |
How to Evaluate a Lease Offer
Regardless of lease type, there are several steps that protect your interests when evaluating commercial office space:
- 1. Request operating expense history: Ask for at least three years of actual expense data. This reveals trends and helps you forecast future costs. A well-managed building will show stable or slowly rising expenses.
- 2. Understand base year vs. expense stop: In a full-service lease, the "base year" sets the baseline for expense pass-throughs. An "expense stop" caps the landlord's contribution at a fixed dollar amount. Both mechanisms shift rising costs to you -- know which one applies.
- 3. Negotiate CAM caps: On NNN and modified gross leases, negotiate a cap on annual CAM increases (typically 3-5%). This protects you from unexpected spikes in maintenance or management costs.
- 4. Compare total occupancy cost: Convert every lease offer to a total annual cost per square foot before comparing. Add base rent, estimated NNN expenses, parking, and any other charges to get a true apples-to-apples number.
- 5. Review the escalation clause: Most leases include annual rent increases of 2-3% or tied to CPI. Over a 5-year term, a 3% annual escalation turns a $22/sf lease into a $25.50/sf lease by year five. Factor this into your long-term budget.
Frequently Asked Questions
- What does NNN mean in commercial real estate?
- NNN stands for triple net, meaning the tenant pays three categories of expenses on top of base rent: property taxes (the first N), building insurance (the second N), and common area maintenance or CAM (the third N). In the Omaha market, these additional costs typically add $6-10 per square foot per year to the quoted base rent. So a $22/sf NNN lease may cost $28-32/sf in total occupancy.
- What is the difference between NNN and full-service?
- In a NNN lease, you pay base rent plus property taxes, insurance, and CAM separately. In a full-service (gross) lease, the landlord bundles all those expenses into a single quoted rate. The full-service rate appears higher, but your total cost may be similar. The key advantage of full-service is budget predictability -- you know exactly what you owe each month. NNN leases can fluctuate as operating expenses change annually.
- Which lease type is most common in Omaha?
- Triple net (NNN) leases are the most common structure for Class A and newer Class B office space in Omaha, particularly in the western suburbs. Full-service leases are more common in downtown buildings with multi-tenant floors. Modified gross leases appear throughout the market, especially in Class B and C buildings where landlords absorb some but not all operating expenses.
- How do I calculate total occupancy cost?
- Start with your base rent per square foot, then add NNN expenses (property taxes, insurance, and CAM -- ask the landlord for current amounts and 3-year history). Add parking costs if charged separately. Factor in any annual escalation clauses (typically 2-3% per year or tied to CPI). Divide any one-time costs like build-out above your TI allowance across the lease term. The result is your true annual cost per square foot -- the only number that lets you compare buildings apples to apples.
- Can I negotiate which expenses I pay in a lease?
- Yes. Lease structures are negotiable, especially in a market like Omaha with healthy vacancy. You can negotiate CAM caps (limiting annual increases to 3-5%), expense stops (a dollar amount above which you pay), base year provisions (you only pay increases above the first year's expenses), or a full conversion from NNN to modified gross. Larger tenants and longer lease terms give you more negotiating leverage.
