For Lease Sign

Triple Net (NNN) Lease

Know what you're agreeing to before you sign.

A Triple Net (NNN) lease can transfer responsibility for building maintenance, repairs, insurance, taxes, and other expenses to the tenant. Before committing to a long-term lease, an independent commercial inspection can help you understand the property's current condition and identify issues that may become your responsibility.

Understanding Triple Net (NNN) Leases

A Triple Net (NNN) lease is a commercial lease in which the tenant may assume responsibility for expenses beyond monthly rent, including property taxes, insurance, maintenance, and certain building repairs. While every lease is different, understanding the condition of the property before signing can help you evaluate future obligations and negotiate from a position of knowledge.

Many prospective tenants assume the landlord will remain responsible for major building systems such as the roof, HVAC equipment, plumbing, or electrical infrastructure. However, depending on the lease terms, some or all of those responsibilities may be assigned to the tenant.

For many business owners, signing a Triple Net lease is one of the largest financial commitments they'll make. Understanding the property's condition before signing can help reduce uncertainty and avoid costly surprises later.

We frequently inspect properties with deferred maintenance that has accumulated over many years. While these conditions may not prevent a business from occupying the building today, they can result in significant repair or replacement costs in the future. An aging HVAC system, deteriorated roof, or neglected parking lot may continue to function for a time—but if those systems fail after you take occupancy, the lease may determine you are responsible for repairs or replacement.

A commercial inspection provides an independent assessment of the property's current condition, helping you identify potential concerns, budget for future expenses, and make informed business decisions before signing a long-term lease.

A commercial inspection cannot determine your legal responsibilities under the lease, but it can provide valuable information about the property's condition so you can better understand the potential risks before you sign. While we do not provide legal advice, we're happy to connect clients with trusted commercial real estate professionals and legal resources who can help interpret lease language and explain potential obligations.

A commercial inspection is designed to provide an objective assessment of the property's current condition. While no inspection can predict every future issue, it can identify existing deficiencies, deferred maintenance, aging building systems, and other conditions that may influence your maintenance planning, lease negotiations, or long-term investment decisions.

A commercial inspection can help identify:

Building Systems

  • Roof concerns and visible signs of deterioration

  • HVAC equipment nearing the end of its expected service life

  • Electrical deficiencies

  • Plumbing problems

  • Sewer concerns (when sewer scoping is included)

  • Fire and life safety concerns

Building Condition

  • Deferred maintenance

  • Structural concerns

  • Moisture intrusion

  • Building envelope deficiencies

  • Interior and exterior deterioration

Site & Safety

  • Parking lot deterioration

  • Sidewalk hazards

  • Exterior maintenance deficiencies

  • Accessibility and safety concerns

Common Questions Before Signing a Triple Net Lease

▼ Why should I have a commercial building inspected before signing a Triple Net lease?

A commercial inspection provides an objective evaluation of the property's condition before you commit to a lease. Identifying deferred maintenance, aging building systems, and potential repair concerns can help you better understand future obligations, plan for anticipated expenses, and make informed business decisions.

▼ Do you follow an inspection standard?

Yes. Commercial property inspections are performed in accordance with the CCPIA Standards of Practice unless a different scope or standard is agreed upon in advance. Every inspection is customized to the property's characteristics and the client's objectives while remaining within the agreed scope of work.

▼ What does a Triple Net lease inspection include?

Every inspection is tailored to the agreed-upon scope of work. Depending on the property and your objectives, inspections may include structural components, roofing, exterior systems, electrical, plumbing, HVAC, interior spaces, parking areas, site conditions, and other accessible building systems. Based on our initial conversation, we can also recommend additional services or specialized evaluations when appropriate.

▼ Will the inspection include an in-depth evaluation of every system?

No. A commercial inspection is performed in accordance with the CCPIA Standards of Practice and is a comprehensive visual evaluation of the property's readily accessible systems and components. While it provides valuable information about the building's overall condition, it is not intended to be an engineering study or destructive examination. If the inspection identifies conditions that warrant additional evaluation, we can recommend qualified specialists to further assess specific systems.

▼ Can an inspection help with lease negotiations?

While we do not provide legal advice or negotiate lease terms, inspection findings often identify conditions that can be valuable when discussing repairs, maintenance responsibilities, or other lease considerations with the property owner.

▼ Will the inspection tell me what I'm responsible for under my lease?

No. A commercial inspection evaluates the physical condition of the property but does not interpret lease language or determine legal responsibilities. However, inspection findings can help you better understand potential maintenance and repair obligations so you can discuss them with your attorney or commercial real estate professional before signing.

▼ Who typically hires 1st Edge Inspections for Triple Net lease evaluations?

Our clients include business owners, franchise operators, investors, commercial real estate professionals, attorneys, and prospective tenants seeking an independent assessment before signing a lease.

▼ Do you inspect occupied buildings?

Yes. We routinely inspect both occupied and vacant commercial properties while working to minimize disruption to tenants and business operations.

▼ Can you inspect restaurants, retail stores, and office buildings?

Yes. We inspect a variety of commercial property types, including office buildings, retail spaces, restaurants, warehouses, industrial facilities, mixed-use properties, multi-family buildings, and more.

▼ Do you use thermal imaging?

Yes. When appropriate for the inspection scope, thermal imaging is used to help identify conditions that may not be visible during a standard visual inspection. It can assist in evaluating building assemblies, identifying moisture intrusion, detecting abnormal thermal patterns within electrical systems, and evaluating heating and cooling performance.

▼ Are there limits to thermal imaging?

Yes. Thermal imaging requires an adequate temperature difference between the interior and exterior of a building to produce meaningful results. In many situations, a temperature difference of approximately 15°F or greater is desirable. Buildings without active utilities or those with doors and windows left open may not provide conditions suitable for effective thermal imaging.

▼ Do you use a drone?

Yes. As an FAA Part 107 Certified Remote Pilot, I use drones when appropriate to safely evaluate roofs, building exteriors, and other areas that may be difficult, unsafe, or impractical to access by conventional means. Every inspection is performed using the method best suited to the property and conditions.

Drone use may be limited by weather conditions, including rain, high winds, or other factors that affect safe flight operations. When a drone cannot be used, we'll discuss alternative inspection methods whenever feasible.

▼ How long does a commercial inspection take?

Inspection times vary depending on the property's size, complexity, occupancy, age, condition, and agreed-upon scope of work. We'll discuss these factors during the proposal process so the inspection scope, schedule, and expectations are clear before the inspection begins.

▼ How quickly can inspections be scheduled?

We understand that commercial real estate transactions often operate on tight timelines. While scheduling can depend on property access and coordination with owners or tenants, we intentionally maintain flexibility in our schedule to accommodate most inspection requests.

▼ How fast can I get the inspection report?

Report delivery timelines are discussed during the proposal process. Our goal is to provide a thorough, accurate, and well-documented report as efficiently as possible. If your transaction has a specific deadline, we'll work with you to meet it whenever feasible.

▼ What happens if significant concerns are found during the inspection?

Inspection findings don't necessarily mean you should avoid leasing the property. Instead, they provide information to help you make informed decisions. Depending on the findings, clients may choose to negotiate repairs, request additional evaluations by specialists, adjust future maintenance budgets, or simply proceed with a better understanding of the property's condition. That's why we often refer to the inspection as your last opportunity to negotiate before the lease becomes your responsibility.
