Industrial Lease Basics - What's Different, and Why It Matters

The Lease Structure: NNN vs. Gross
The most important financial concept in industrial leasing is understanding what type of lease you're signing. The two most common structures are triple net and gross, with many variations in between.

• Triple Net (NNN): In a triple net lease, you pay base rent plus your proportionate share of three expense categories: property taxes, building insurance, and common area maintenance. This is by far the most common structure for industrial space. Your monthly obligation is the base rent number plus these pass-throughs, which add to your all-in cost. When you're comparing industrial options, always compare total occupancy cost — not just the base rent.
• Modified Gross or Full Gross: In a gross lease, the landlord bundles most or all operating expenses into the base rent. These are less common in industrial leases than they are in office leases, but they do exist, particularly in older multi-tenant industrial parks or flex buildings. They offer more cost predictability, but often carry a higher base rent to compensate.

The practical impact: when a landlord quotes $8.00 per square foot on a NNN lease, your real cost might be $10.50 to $11.50 per square foot once taxes, insurance, and CAM are added. Always ask for an estimate of NNN charges before comparing properties.

The Physical Specs That Drive Value

In office leasing, simple physical attributes of the building or offices to consider are floor plan, windows, and location. In industrial leasing, the actual physical specifications of the building are the most important factor in whether the space actually works for your business. Here's what to evaluate:

• Clear Height: This is the usable vertical height inside the warehouse, measured from the finished floor to the lowest obstruction (usually a beam or sprinkler head). Clear heights typically range from 18 feet in older buildings to 36 or 40 feet in modern bulk distribution facilities. If you're racking product, running lifts, or need to stack inventory, clear height is non-negotiable — a space with inadequate clear height simply cannot serve your operation regardless of how reasonable the rent is.

• Dock Doors and Grade-Level Doors: Dock-high doors allow semi-trucks to back up and load/unload at trailer bed height — critical for distribution and freight-heavy operations. Grade-level (or drive-in) doors sit at floor level, useful for smaller vehicles, forklifts, and certain manufacturing processes. Know how many you need and what configuration works for your trucks and your traffic flow.

• Truck Court Depth: The area behind the building where trucks maneuver is called the truck court. Standard semi-trucks require roughly 130 feet of depth to safely back into a dock door. Inadequate truck court depth creates operational headaches — or worse, safety issues. This spec matters and varies significantly across industrial properties.

• Column Spacing: Columns interrupt your floor plan. Wide column spacing (50x50 feet or greater) gives you more flexibility in racking and layout design. Tight column spacing can seriously constrain how you use the space.

• Electrical Power: Manufacturing, cold storage, EV charging, and heavy equipment operations require significant electrical infrastructure. Know your power requirements — ask for the available amps and voltage — before falling in love with a space that can't support your operations. Upgrading electrical service is expensive (and sometimes impossible) depending on the building's infrastructure.

• Sprinkler System: Almost all modern industrial buildings have fire suppression systems, but the type matters. ESFR (Early Suppression Fast Response) sprinklers are the standard for high-bay warehousing and racking. Older systems may not support certain storage configurations or rack heights. Check with your insurance carrier and any applicable fire codes.

Office Finish and Ratio

Most industrial buildings include some amount of office space — a front office for staff, a dispatch area, a showroom, or a breakroom. This is typically called the office component or office finish.

Pay attention to the ratio of office to warehouse space. A building that is 20% office and 80% warehouse may be perfect for one company and completely wrong for another. Office space typically has different build-out standards (HVAC, lighting, ceiling heights) and often a different cost to build. If you need to add or reduce office space, factor that into your TI conversation with the landlord.

Lease Term Expectations

Industrial leases tend to run longer than office leases, particularly for larger spaces or any deal that requires significant build-out or infrastructure investment. Three to five years is a minimum for most landlords in multi-tenant industrial. Single-tenant, larger, or build-to-suit deals routinely carry seven to ten-year terms.

The reason is straightforward: industrial landlords are making real investments in tenant improvements and building modifications. They need the lease term to justify and amortize that investment. If you need maximum flexibility, be prepared to pay for it — shorter terms typically come with higher rent and reduced concessions.

Environmental and Zoning Considerations

Industrial space sits in zoning classifications that office space doesn't. Before signing, verify that your intended use is permitted under the property's zoning designation. Light manufacturing, warehouse/distribution, hazardous material storage, and certain types of processing each carry different zoning requirements and may require specific permits.

Additionally, industrial properties sometimes carry environmental history. Prior tenants may have used chemicals, solvents, or other materials that left behind contamination. A Phase I Environmental Site Assessment — and sometimes a Phase II — is standard practice in industrial due diligence and should not be skipped.

The Bottom Line

Industrial real estate can be an excellent, cost-effective solution for growing your business — but only if the space actually works for operations. The biggest mistakes industrial tenants make:

• underestimating the total occupancy cost by focusing only on base rent
• failing to verify physical specs against their operational needs
• signing leases too short to get meaningful concessions

Go into your industrial search with a clear understanding of your specs — clear height, power, dock requirements, and square footage — and evaluate every building against that standard before anything else.
