A lease where the tenant pays everything is called an absolute net lease, sometimes known as a bondable lease or a “hell or high water” lease. Under this arrangement, you pay base rent plus every operating cost tied to the property: real estate taxes, insurance, common area maintenance, routine repairs, structural repairs, roof replacement, and even reconstruction if the building is damaged or condemned. Some versions strip away your right to terminate under any circumstances, which is where the “hell or high water” nickname comes from. Absolute net leases show up most often in sale-leaseback transactions with credit tenants.1Legal Information Institute. Net Lease
The more common cousin is the triple net lease (NNN), where you pay base rent plus property taxes, insurance, and common area maintenance, but structural and catastrophic obligations stay with the landlord. The tradeoff for either arrangement is a lower base rent than you’d see in a gross lease, where the landlord bundles all costs into one higher monthly figure.
Where Absolute Net Sits on the Spectrum
Net leases run on a sliding scale. The further along it you go, the more expenses move from the landlord’s column to yours.
- Single net lease (N): base rent plus property taxes. Landlord still handles insurance and maintenance. Least common.
- Double net lease (NN): base rent, taxes, and building insurance. Landlord keeps structural maintenance and major repairs.
- Triple net lease (NNN): base rent, taxes, insurance, and common area maintenance. Most routine repairs are yours. This is the workhorse of commercial leasing, especially for freestanding retail and single-tenant buildings.
- Absolute net lease: everything above, plus structural repairs, roof replacement, and rebuilding after a casualty or condemnation. Termination rights are often eliminated.
The “net” in each name refers to what the landlord receives: rent that is net of operating expenses, because those costs flow through to you.1Legal Information Institute. Net Lease
What “Everything” Actually Covers
When a lease makes you responsible for operating expenses, those expenses break into several categories. Vague lease language in any of them is where unexpected bills come from.
Property Taxes and Assessments
You pay your proportionate share of real property taxes levied on the building and land. In a single-tenant building, that’s the full tax bill. In a multi-tenant property, your share depends on how the lease defines “proportionate.” A calculation based on total rentable space gives you a smaller share than one based on actually rented space, because the first method forces the landlord to absorb the cost of vacant units while the second spreads the full tax bill only among current tenants.2Nolo.

Building Insurance
You contribute to insuring the building’s structure: hazard insurance, general liability, and sometimes flood or earthquake coverage depending on location. Your lease should specify whether you’re paying a pro-rata share of a blanket policy the landlord carries or purchasing your own. Either way, you still need a separate commercial general liability policy for your own operations.
Common Area Maintenance
CAM charges cover shared spaces: parking lots, lobbies, hallways, landscaping, exterior lighting, elevators, and security. Your share is typically a fraction of total leasable area. Some landlords add an administrative or management fee on top of actual CAM costs, often expressed as a percentage of total operating expenses. That fee is negotiable, and you should know it exists before you sign.
Structural Repairs and Rebuilding
This is what sets absolute net apart from triple net. The roof, the foundation, the load-bearing walls, the HVAC system at the end of its life, and the building itself after a fire or storm all become your financial responsibility. In a triple net lease, most of this stays with the landlord. In an absolute net lease, it doesn’t.
Utilities and In-Space Costs
Electricity, water, gas, internet, and trash removal within your leased space are almost always your responsibility in any net lease. If the building lacks separate meters, utility costs may be rolled into CAM and allocated by square footage, which can mean subsidizing a neighbor who runs heavy equipment while you run a quiet office.
How Your Share Gets Calculated
The math is straightforward, but the inputs matter. Most leases use one of two formulas to calculate your share of taxes, insurance, and CAM.
The first divides your leased square footage by the building’s total rentable square footage. Lease 2,000 square feet in a 10,000-square-foot building and your share is 20%, regardless of occupancy. The second divides your square footage by the space actually rented, which inflates your share when the building has vacancies. Using the same example, if only 5,000 square feet are rented, your share jumps to 40%.2Nolo. Commercial Triple Net Leases: Allocating Taxes
Push for the total-rentable-area method. The vacancy risk belongs to the landlord. If the landlord insists on the rented-space method, negotiate a cap so your share never exceeds what you’d pay if the building were fully occupied.
Repairs vs. Capital Improvements
Most net lease disputes start here. A repair restores something to its original working condition without adding value or extending its life. Replacing a gasket on a generator, patching a section of roof, or fixing a broken pipe is a repair. A capital improvement goes further: it prolongs the property’s useful life, increases its value, or adapts it for a different use. Replacing an entire water main with a larger one is an improvement, not a repair.
In an absolute net lease, capital expenditures land squarely on you. If you can’t negotiate them out entirely, negotiate amortization. Instead of paying the full $50,000 cost of a roof replacement in year eight of a ten-year lease, you’d pay the cost spread over the roof’s useful life, so you’re only covering the portion you’ll actually benefit from. A common landlord counter is amortization over the shorter of the useful life, five years, or the remainder of your lease. That’s still better than a lump sum. Push for the longest amortization period you can get.
Clauses That Decide Whether the Lease Is Survivable
Expense allocation gets most of the attention, but a handful of other clauses determine whether this lease works for you or quietly bleeds you over a decade.
Operating Expense Caps
An expense cap limits how much your operating costs can rise year over year, typically expressed as a percentage. Without one, a reassessment that doubles the tax bill or an insurance spike after a natural disaster hits your bottom line directly. A related mechanism is the base year stop: the landlord covers operating expenses up to the amount incurred in the first year of your lease, and you pay only the increases above that baseline. Either approach gives you some protection against cost surges you can’t control.
Rent Escalation
Most net leases include scheduled rent increases, usually a fixed dollar amount, a fixed percentage, or an adjustment tied to the Consumer Price Index. Fixed increases give you certainty. CPI-tied increases track inflation but can be unpredictable in volatile years. If you agree to CPI escalation, negotiate an annual cap.
Casualty and Condemnation
These clauses spell out what happens if the building is severely damaged or taken by the government through eminent domain. In a standard triple net lease, you typically have the right to terminate if damage is extensive. In an absolute net lease, you may not, and you could be on the hook to rebuild. Make sure you know which version you’re signing. The clause should also address how insurance proceeds are handled and whether you receive any compensation for lost leasehold interest in a condemnation.
Assignment and Subletting
If your business outgrows or downsizes out of the space, your ability to assign the lease or sublet depends on this clause. Most leases require the landlord’s consent. You want language specifying that consent won’t be unreasonably withheld. Without that qualifier, a landlord can simply say no and leave you paying for space you can’t use.
Subordination, Non-Disturbance, and Attornment
An SNDA protects you if the landlord’s lender forecloses. The non-disturbance piece means the new owner can’t evict you as long as you’re current on your lease. The attornment piece requires you to recognize the new owner as your landlord and continue performing. Without an SNDA, a foreclosure could force you out of a space you’ve invested heavily in building out. If the property has a mortgage, request an SNDA before signing.
Audit Rights Over the Landlord’s Numbers
You’re paying a proportionate share of actual operating expenses, which means you’re trusting the landlord’s accounting. That trust should be backed by contractual audit rights.
A strong audit clause does three things. The landlord delivers an annual reconciliation statement, typically within 90 to 120 days of the lease year’s end, breaking down actual expenses by category against the estimates you paid monthly. You have the right to review the landlord’s books and supporting documentation, either yourself or through a third-party auditor. And the lease specifies a lookback period for recovering overcharges, commonly one to three years.
One provision worth fighting for: if an audit reveals an overcharge above a stated threshold (3% to 5% is common), the landlord reimburses your audit costs. That creates a real incentive for accurate bookkeeping. Without audit rights, you’re writing checks against numbers you can’t verify.
Carve-Outs to Insist On
Not every cost a landlord incurs belongs in your expense reconciliation. Tenants with leverage routinely exclude specific items from CAM pass-throughs: costs of correcting building code violations that predate your lease, legal fees from disputes with other tenants, costs of finding and signing new tenants (leasing commissions, advertising, tenant improvement allowances), and capital expenditures that benefit the landlord beyond your lease term.
Depreciation on the building itself should never appear in your CAM statement, nor should the landlord’s income taxes or debt service. If the landlord uses a property management company, cap the management fee at a stated percentage rather than leaving it open-ended. These exclusions won’t appear in a standard lease form. You have to add them, and the time to do that is before you sign.
Tax Treatment of What You Pay
Rent you pay for business property is generally deductible as an ordinary business expense, and that includes the operating costs you cover under a net lease. Federal tax law allows a deduction for “rentals or other payments required to be made as a condition to the continued use or possession” of property used in your business, as long as you’re not building equity in the property.3Office of the Law Revision Counsel. 26 U.S. Code 162 – Trade or Business Expenses Property taxes, insurance premiums, and CAM charges you pay as a condition of your lease fall under this umbrella.4Internal Revenue Service. Small Business Rent Expenses May Be Tax Deductible
If you prepay rent, the timing of your deduction depends on your accounting method. Cash-basis taxpayers can deduct advance rent in the year paid, but only if the prepayment covers no more than 12 months and doesn’t extend beyond the end of the following tax year. Anything beyond that must be spread over the period it covers. Accrual-basis taxpayers deduct only the portion that applies to the current year regardless of when they pay.
For long-term leases with significant rent escalations, there’s one more thing to flag with a tax advisor before signing: if total payments exceed $250,000, the IRS may require special accrual rules under Section 467, which can change when you recognize the expense.5Office of the Law Revision Counsel. 26 U.S. Code 467 – Certain Payments for the Use of Property or Services
