Free Modified Gross Lease Agreement Template

A modified gross lease agreement splits operating costs between landlord and tenant, rather than leaving one side to carry them all. So base rent covers an agreed set of expenses, while the tenant pays the rest directly. Both sides therefore need to read those clauses closely, because that is where the real price sits.

Generally, the structure sits between two extremes. A fully gross deal folds everything into rent, while a triple net deal pushes taxes, insurance, and upkeep onto the tenant.

Because every split is negotiated, no two versions look alike. One building may keep taxes and insurance with the landlord, while another hands utilities and janitorial work to the tenant.

That flexibility is the whole point. Landlords limit their exposure to rising costs, and tenants avoid paying for services they never use.

A modified gross lease agreement usually leans on one of two mechanics: a base year or an expense stop. Both cap what the landlord absorbs and pass later increases along.

A base year fixes the landlord’s share at the operating costs recorded during the first full year of the term. Afterward, the tenant pays its proportionate share of anything above that figure.

An expense stop works from a stated dollar amount instead of one year of actuals. Once real costs pass the stop, the tenant covers the difference on whichever categories the lease names.

Either route ends in reconciliation. The landlord estimates the tenant’s share, bills it monthly, then trues up against actual spending once the year closes.

Ask for audit rights and a cap on controllable expense increases. Otherwise, a predictable-looking lease can still produce an unpredictable year-end invoice.

Reach for a shared-cost structure when neither bundled rent nor a full pass-through suits the building. Multi-tenant office properties, medical suites, and mixed-use blocks fit especially well.

Landlords favor it where usage varies sharply between occupants. For example, a quiet accounting practice and a busy imaging clinic should never carry the same utility share.

Tenants favor it when they want predictability without funding services they never touch. So a firm with its own cleaning crew can strip that cost out of base rent entirely.

The approach fits poorly on single-tenant buildings. In that case a net structure is simpler, because there is nobody else to apportion costs against.

A workable modified gross lease agreement leaves no expense category unassigned. Cover each element below in writing.

Parties, Premises, and Share

Name both parties and describe the space by suite number and area. Then state the tenant’s proportionate share as a percentage, since every pass-through calculation depends on it.

Term and Options

Next, set the start and end dates, plus any renewal or expansion option. Note the notice each option requires and who must give it.

Base Rent

Likewise, record the monthly figure, the due date, and any scheduled increase. Keep this separate from expense charges so both sides can read the numbers cleanly.

The Expense Split

Then list by name which costs the landlord keeps and which the tenant picks up. Ambiguity here is the single most common source of later disputes.

Base Year or Expense Stop

State which mechanism applies and the exact year or figure it uses. Also define which categories count toward it and which sit outside the calculation.

Estimates, True-Ups, and Audit Rights

Explain how estimates are set, when statements arrive, and how the tenant may review them. Furthermore, note the window for raising a challenge.

Utilities and Services

Also say whether the suite is separately metered, and name who arranges cleaning, security, and after-hours climate control.

Maintenance, Insurance, and Default

Divide repair duties between building systems and the tenant’s interior. Then set the coverage each side carries, what counts as a breach, and how a breach may be cured.

Requirements for commercial leases change from place to place, and an expense structure does not alter them. Your state’s official website is the right starting point, since recording and disclosure practices differ.

A signed written lease is the record both sides will lean on. Date every signature, and initial any change made by hand.

Worth confirming before you commit:

• Which definition of operating expense applies, and is capital work excluded?
• Does the landlord hold clear title, or does a master lease sit above this one?
• Do building rules or lender requirements limit what is being promised?

Complex splits, expansion rights, and large build-outs all justify professional help. A commercial real estate attorney or a tenant representative can price the expense structure against comparable buildings nearby.

The lease binds landlord and tenant to each other. Nothing in it changes what a lender or a local authority separately requires.

Sign before occupancy and before any allowance gets spent. A lease papered after the work starts rarely reflects what the parties actually agreed.

Most commercial landlords now accept e-signed leases. Even so, confirm the lender’s position, because some financing terms still call for originals.

Immediately after signing:

1. Circulate a complete signed copy with all exhibits, rules, and expense schedules.
2. Log the base year figure or expense stop where your finance team will find it.
3. Calendar the annual statement date, the audit window, and every renewal notice.
