Modified Gross Lease
A middle-ground structure where landlord and tenant split operating expenses in a negotiated way.
01
What It Is
A modified gross lease sits between a gross lease and a net lease. The tenant pays base rent plus some specific expenses — often utilities and janitorial — while the landlord keeps responsibility for others such as property taxes, insurance, and structural maintenance.
Because the split is negotiated rather than standardized, two modified gross leases on the same street can allocate costs very differently.
02
Why It Matters
This is the most common structure in many small-market commercial buildings, and it is also the structure most often misunderstood. The label tells you almost nothing; the expense allocation language tells you everything.
Reading the allocation carefully lets you build an accurate occupancy budget and compare offers on equal footing.
It also clarifies operational responsibility. Knowing in advance who calls the HVAC contractor and who pays for the visit prevents friction later.

Common Misconceptions
- "Modified gross is a standard, defined structure." It is a negotiated arrangement that varies property to property.
- "If it isn't listed as mine, it's the landlord's." Silence in a lease is a risk, not a protection. Unassigned responsibilities become a dispute.
- "The split can't be negotiated." Expense allocation is one of the more negotiable elements of a lease, particularly in a soft market.

Questions to Ask
- Can we list every operating expense and mark who pays each one?
- Are any expenses capped, and do caps apply annually or cumulatively?
- How are shared utilities allocated when space is not separately metered?
- Who handles roof, HVAC, plumbing, parking lot, and snow removal?
- How and when will I be billed for my share of shared costs?
