The Beginner’s Guide to Leasing Your First Warehouse Space: Terms You Need to Know

Leasing your first warehouse space is a significant step for any growing business. However, the industrial real estate world comes with its specialized vocabulary that can be confusing and intimidating for first-time tenants. This guide breaks down the essential terms and concepts you’ll encounter during the warehouse leasing, helping you confidently navigate negotiations.

Lease Structure Terms

Triple Net (NNN) Lease

The most common industrial lease type where the tenant pays:

• Base rent
• Property taxes
• Insurance
• Maintenance costs

In a true NNN lease, you’re responsible for virtually all expenses related to the property, including structural components and common areas.

Modified Gross Lease

A middle-ground option where:

• Tenant pays base rent and some operating expenses
• Landlord typically covers structural components and common areas
• Specific responsibility split varies by lease

Full Service/Gross Lease

Less common in industrial properties, but sometimes used for flex spaces:

• Tenant pays one flat rental amount
• Landlord covers most or all operating expenses
• Often includes utilities and janitorial services

Base Rent

The fundamental lease payment, typically quoted as:

• Annual rate per square foot (e.g., $8.50/SF/year)
• Monthly payment for the entire space

Escalations

How your rent increases over the lease term:

• Fixed increases: Set percentage (e.g., 3% annually) or dollar amount
• CPI adjustments: Tied to Consumer Price Index
• Market rate adjustments: Adjusted to reflect market rates at specific intervals

Space Measurement Terms

Rentable Square Footage (RSF)

The total area you pay rent on, including:

• Your exclusive space (warehouse, office, mezzanine)
• Your proportionate share of common areas

Industrial Gross Square Footage

How warehouse space is typically measured:

• Usually measured from the outside walls
• Often includes your portion of shared walls
• Generally does not include a separate common area factor

Office Add-On Factor

For industrial properties with office space:

• Office areas may include a load factor (typically 10-15%)
• Accounts for corridors, restrooms, and shared areas within the office portion

Clear Height

Usable height from floor to lowest obstruction (beams, lights):

• Modern warehouses: 28-36+ feet
• Older buildings: 18-24 feet
• Determines stacking capacity and cubic storage potential

Financial Terms

Security Deposit

Upfront payment to protect the landlord:

• Typically 1-3 months’ rent
• May increase for tenants with limited history or credit

• Can cover offices, lighting, additional power, docks, etc.
• Often amortized into the rental rate

Lease Term Concepts

• Must be exercised within a specific notification window

Right of First Refusal (ROFR)

Opportunity to match offers for adjacent space:

• Allows for potential expansion

Early Termination Right

Ability to end the lease before the full term:

• Usually requires significant notice (6-12 months)
