Understanding Your School Lease

Commercial leases are written by and for landlords. As a school founder, you are likely signing one of the largest financial commitments of your organization, and the terminology can be opaque. This guide breaks down the most important lease concepts in plain language so you know what you are agreeing to, and how your lease fits into your overall financial picture.

Gross vs. NNN: understanding lease structures

The two most common commercial lease structures:

Gross lease (full-service): You pay a single monthly rent that includes most operating expenses. The landlord covers property taxes, insurance, and maintenance. Simpler to budget, but the base rent is higher.

Triple Net Lease (NNN): You pay a lower base rent plus your proportional share of three additional costs: property taxes, insurance, and Common Area Maintenance (CAM). NNN is the most common lease structure for schools.

The formula: Gross Rent = Base Rent + Operating Expenses (NNN)

With NNN, your actual monthly cost is Base Rent + NNN Charges. NNN charges typically add $3 to $8 per square foot per year, depending on the property. Always ask the landlord for the current year's NNN estimates and at least two years of actuals.

CAM charges: what you are really paying for

Common Area Maintenance (CAM) is the landlord's cost to maintain shared spaces and building systems. It typically includes:

Watch out for:

Tenant improvements (TI)

Most commercial spaces need modifications to function as a school. Tenant Improvement (TI) allowances are the landlord's contribution to those build-out costs. This is also known as leasehold improvements -- custom renovations to leased spaces, funded by either the tenant or landlord.

How TI works:

Common school build-out needs:

TI allowances are negotiable. Longer lease terms (7-10 years) often come with more generous TI because the landlord recovers the cost over more years of rent.

Escalation clauses and rent increases

Almost every commercial lease includes annual rent increases. Common structures:

For schools, fixed escalations of 2-3% are ideal because they allow accurate long-term budgeting -- essential when your revenue is relatively predictable.

Financial metrics that matter for your lease

Understanding these financial metrics helps you evaluate whether a lease is affordable:

Debt Service Coverage Ratio (DSCR) measures how well your school can cover its annual debt payments with income.

Maximum Annual Debt Service (MADS) is the highest amount your school will owe in debt payments in a single year over the life of a loan. Lenders use MADS to assess if your school can handle future obligations. Aim for MADS to be less than 15% of total revenue.

Facilities margin: Target 20-24% of recurring public revenue for total facility costs (debt service + M&O combined).

Frequently asked questions

What is a triple net (NNN) lease for a school?

A triple net lease means the tenant pays a lower base rent plus their proportional share of three operating expenses: property taxes, insurance, and common area maintenance (CAM). NNN is the most common lease structure for schools. Your total cost is: Gross Rent = Base Rent + Operating Expenses.

What is a good DSCR for a school facility?

Aim for a Debt Service Coverage Ratio of at least 1.15 at full enrollment. Early-stage schools may need philanthropy to achieve at least 1.1 while enrollment is growing. A DSCR below 1.0 means the school cannot cover its debt payments from operating income.

How much TI allowance should a school expect from a landlord?

Tenant improvement allowances typically range from $15 to $40 per square foot, depending on the lease term, property condition, and local market. Longer lease terms (7-10 years) generally come with more generous TI because the landlord recovers the cost over more years of rent.

What is Maximum Annual Debt Service (MADS)?

MADS is the highest annual debt payment (principal plus interest) your school will owe in any single year over the life of a loan. Lenders use it to assess affordability. Aim for MADS to be less than 15% of your total revenue.
