Gross Leases: One Payment Covers (Almost) Everything

What Is a Gross Lease?

A gross lease is a commercial lease where the tenant pays a single, all-inclusive rent amount, and the landlord covers property operating expenses — property taxes, insurance, and maintenance. From the tenant's perspective, budgeting is simpler because there is one predictable monthly payment.

Gross leases are common in multi-tenant office buildings, where individual tenants would find it impractical to manage shared property expenses directly.

Full-Service Gross vs. Modified Gross

Full-Service Gross Lease

The landlord pays all operating expenses. The rent is higher to account for this, but the tenant has complete cost certainty.

Modified Gross Lease

The most common variation. The tenant pays base rent plus some specific expenses — often utilities, janitorial services, or increases in operating expenses above a base year amount. This hybrid sits between a pure gross lease and a net lease.

The Base Year Trap

Many modified gross leases use a base year concept: the landlord covers operating expenses at the level they were during the first year of the lease, and the tenant pays any increases above that amount in subsequent years.

Watch for:

  • Artificially low base years: If operating expenses in year one were unusually low, you will pay more in escalations
  • Expense spikes: A major property tax reassessment or insurance increase can substantially raise your costs
  • Unclear base year calculations: Ensure the base year methodology is clearly defined

When to Consult a Lawyer

Before signing a gross or modified gross lease, consider having an attorney review the base year provisions, expense pass-through language, and any carve-outs that shift costs to you.
