For entrepreneurs, signing a commercial lease is often an exciting milestone. It means growth, stability, and a new home for their business. But behind the excitement, commercial property agreements are full of hidden clauses that can cause headaches—or even financial ruin—if overlooked.
Many small business owners assume that signing a lease is just a matter of agreeing on rent and moving in. The reality is that property law plays a central role in business success. Understanding the legal framework of commercial real estate can save business owners thousands of dollars and protect them from disputes with landlords, contractors, or even municipalities.
Triple Net Leases: More Than Just Rent
One of the most common surprises for small businesses is the “triple net lease”. Unlike residential leases, which usually include maintenance and utilities, a triple net lease passes on costs for taxes, insurance, and maintenance directly to the tenant.
For a small business, these costs can add up quickly. Imagine budgeting $3,000 per month for rent, only to discover that your share of property taxes and maintenance adds another $1,200.
Takeaway for business lawyers: Always explain to clients what “net” means in their lease and how it will impact their bottom line. Encourage clients to ask for a clear breakdown of all additional charges.
Repair Obligations: Who Fixes What?
Another common trap is repair and maintenance clauses. Many commercial leases require tenants to be responsible for everything inside the space—sometimes even major systems like HVAC or plumbing.
In Ontario, unless the lease explicitly says otherwise, landlords are not automatically required to maintain these systems. If the furnace breaks in the middle of winter, an unprepared tenant may be on the hook for a $10,000 repair.
Takeaway for entrepreneurs: Never assume landlords are responsible for repairs. Review the maintenance clause carefully and consider negotiating caps on repair costs.
Zoning and Permits: The Silent Deal-Breaker
Zoning laws often determine whether a business can operate legally in a chosen space. For example, a restaurant tenant may sign a lease, only to discover that the property is zoned for retail but not food service.
Municipalities enforce zoning strictly under the Planning Act and local zoning by-laws. If a business is shut down because of zoning violations, landlords rarely refund rent or cover losses.
Takeaway for lawyers and tenants: Always verify zoning compliance before signing. Tenants should obtain written confirmation from the municipality or make the lease conditional on proper zoning.
Personal Guarantees: Risk Beyond the Business
Most landlords require personal guarantees on small business leases. This means that if the business fails, the owner is personally liable for rent. For startups with uncertain cash flow, this can turn a business setback into personal bankruptcy.
Ontario law allows these guarantees to be enforced fully unless negotiated otherwise. Many tenants don’t realize the long-term risk they are taking.
Takeaway: Tenants should push for limited guarantees (for example, capped at 12 months’ rent) or “burn-off clauses” where liability decreases over time.
Tenant Improvements: Who Pays? Who Owns Them?
Small businesses often need to customize their space—building counters, installing equipment, or upgrading electrical systems. But under many leases, these improvements become the landlord’s property once installed.
If the business closes or moves, the tenant may lose tens of thousands of dollars in invested improvements. Worse, some leases require the tenant to restore the unit to its original condition upon leaving, adding demolition costs.
Takeaway: Always clarify improvement terms in writing. Who pays, who owns, and what happens at lease end should never be left to assumption.
Dispute Resolution: Court or Arbitration?
Commercial leases often contain dispute resolution clauses, requiring arbitration or mediation before court action. While alternative dispute resolution can be faster, it also means business owners may give up the right to be heard in Small Claims Court.
Lawyers advising clients should review these clauses closely. A poorly drafted arbitration clause can trap a business in costly private proceedings.
The COVID-19 Lesson: Force Majeure Clauses
The pandemic exposed a major blind spot in commercial leases: force majeure provisions. These clauses excuse performance in the event of “unforeseen circumstances,” but most commercial leases specifically exclude rent obligations from force majeure.
During the pandemic, these clauses meant that when businesses were forced to shut down, tenants were still liable for rent. Unless governments stepped in with relief programs, many businesses simply could not survive.
Takeaway for future leases: Negotiate force majeure clauses that fairly address rent obligations in emergencies.
How Property Management and Legal Advice Work Together
For small business owners, property law can feel overwhelming. But the solution isn’t to avoid it—it’s to approach leasing with the right team:
- Lawyers can review and negotiate clauses, protecting clients from hidden risks;
- Property managers can ensure compliance with zoning, maintenance, and landlord-tenant obligations; and
- Business owners gain peace of mind, knowing they are building on a solid legal foundation.
When these three work together, commercial leasing becomes less of a gamble and more of a strategic move for long-term growth.
The Bottom Line: Read Beyond the Rent
For small business owners, a commercial lease is one of the most important contracts they will ever sign. It sets the stage not only for rent, but for risk, responsibility, and ultimately, business success.
Ignoring property law in leasing decisions is like ignoring the foundation of a building. It may look fine on the surface, but without stability underneath, everything is at risk.
For entrepreneurs ready to grow, understanding the legal side of property management isn’t optional — it’s essential. And for lawyers advising clients, breaking down these issues in plain language is one of the most valuable services you can provide.
