Types of Commercial Leases: What Business Tenants Need to Know

When searching for the right commercial space for your business, one of the most important considerations is the type of lease being offered. Not all commercial leases are created equal. The structure of your lease will determine how expenses are shared between the Landlord and the Tenant, and can significantly impact your bottom line.

Here’s a breakdown of the most common types of commercial leases in Ontario, along with their key features, pros, and cons.


1. Gross Lease (Full-Service Lease)

In a gross lease, the Tenant pays one fixed monthly rent, and the Landlord covers most operating expenses, such as property taxes, building insurance, and maintenance. This type of lease simplifies budgeting by offering a single, predictable payment.

Pros:

  • Easy to manage, with no surprise charges
  • Ideal for small businesses or short-term arrangements

Cons:

  • Higher base rent, since expenses are built in
  • Little control over operating costs

Commonly used in: Multi-tenant office buildings and small retail plazas.


2. Net Lease

A net lease separates rent from operating costs. The Tenant pays a lower base rent but is also responsible for one or more property-related expenses. There are several types:

  • Single Net (N): Tenant pays rent + property taxes
  • Double Net (NN): Rent + taxes + insurance
  • Triple Net (NNN): Rent + taxes + insurance + maintenance (and often utilities)

Triple Net leases are especially common in Ontario and essentially transfer most of the cost responsibility to the tenant.

Pros:

  • Lower base rent
  • Transparent cost structure

Cons:

  • Costs can fluctuate with building expenses
  • Higher responsibility for repairs and ongoing fees

Common Use: Office buildings, industrial properties, and standalone commercial units.


3. Modified Gross Lease

A modified gross lease is a hybrid that blends elements of gross and net leases. The Landlord may pay certain expenses (e.g., janitorial services, insurance), while the Tenant covers others (e.g., utilities or property taxes). This arrangement offers more flexibility and can be tailored to meet both parties’ needs.

Pros:

  • Balanced cost-sharing
  • Negotiable terms

Cons:

  • Must clearly define who pays for what to avoid confusion

Common Use: Mixed-use developments or buildings with varying tenant requirements.


4. Percentage Lease

A percentage lease is often used in retail environments, particularly shopping malls or food courts. In this model, the Tenant pays a base rent plus a percentage of gross sales once a certain sales threshold is met.

Example: Base rent of $2,000/month plus 5% of annual sales over $500,000.

Pros:

  • Aligns rent with business performance
  • Lower fixed rent during slower periods

Cons:

  • Requires accurate sales forecasting
  • May involve reporting obligations or audits

Common Use: Retail stores, cafés, restaurants, and other high-traffic locations.


Information to Seek Before You Sign

Regardless of the lease type, it’s important to understand the fine print. Ask your prospective Landlord:

  • What type of lease is being offered?
  • Are Common Area Maintenance (CAM) charges capped or unlimited?
  • How are annual rent increases calculated—fixed percentage, CPI, or actual costs?
  • Can they provide a breakdown of past operating expenses?

Every cost matters, especially in a long-term lease.


Comments

Choosing the right lease structure can mean the difference between a stable business plan and unexpected financial stress. Whether you prefer the simplicity of a gross lease or the cost control of a net lease, make sure the terms are clearly defined, and always review them with a commercial real estate lawyer before signing.
