Mandatory Clauses for Commercial Leases in New Brunswick

Unlike residential rentals, commercial leases in New Brunswick offer very few built-in protections for tenants. It is critical to negotiate clear clauses regarding Base Rent, TMI (Taxes, Maintenance, Insurance), and exact repair responsibilities before signing to protect your business’s financial future.

Securing the perfect physical location is often the most vital step in launching a successful business. Whether you are eyeing a retail storefront in downtown Fredericton or an industrial warehouse in Moncton, the lease you sign will dictate your overhead costs for years.

Many new business owners mistakenly assume that commercial leases operate like residential ones. In reality, commercial tenancy law in New Brunswick strongly favours the landlord and relies almost entirely on the specific words written in your contract. To avoid surprise expenses that could bankrupt your startup, your commercial lease must include several mandatory, clearly defined clauses.

Step-by-Step Process for Reviewing the Lease

Negotiating a commercial lease is a high-stakes business transaction. You should never sign the landlord’s standard template without carefully reading every single page. Here is a systematic approach to evaluating the crucial clauses in your agreement.

Step 1: Clarify the Rent Structure (Base vs. TMI)

You must understand exactly what you are paying each month . The contract will usually outline the Base Rent (the cost per square foot for the space itself). However, most commercial leases in New Brunswick are “Triple Net” (NNN) leases. This means you are also responsible for your proportionate share of TMI (Property Taxes, Maintenance, and Insurance). Your lease must explicitly state how TMI is calculated and cap how much it can increase each year.

Step 2: Define Maintenance and Repair Duties

In a commercial setting, if the HVAC system breaks down or the roof leaks, the landlord is not automatically obligated to fix it. The lease must include a clear maintenance clause. Generally, tenants are responsible for everything inside their specific unit (like light fixtures and plumbing), while the landlord is responsible for structural elements (like the foundation and exterior walls). Make sure this dividing line is incredibly clear.

Step 3: Negotiate the Permitted Use and Exclusivity

Your lease must contain a Permitted Use clause that clearly allows you to operate your specific type of business. If you are opening a coffee shop, the lease must state that food service is allowed. Additionally, try to negotiate an Exclusivity Clause. This legally prevents the landlord from renting the unit next door to a direct competitor, protecting your customer base within that plaza or building.

Step 4: Establish Renewal Options

A successful business takes time to build a local reputation. You do not want to be forced out after five years just when you are getting busy 📍. Ensure your contract includes an “Option to Renew” clause, guaranteeing you the right to extend the lease for another term (e.g., an additional 5 years) at a fair, pre-negotiated market rate rather than an arbitrary rent spike.

Comparing Lease Types in New Brunswick

Understanding the fundamental structure of your commercial lease is critical. Here is a breakdown of the most common formats you will encounter:

Type of Commercial LeaseWhat the Tenant Pays
Gross LeaseYou pay one flat, fixed monthly fee. The landlord uses that money to cover all taxes, insurance, and building maintenance.
Net Lease (Single or Double)You pay the base rent plus one or two additional building expenses, such as property taxes or building insurance.
Triple Net Lease (NNN)You pay base rent plus your exact share of all Property Taxes, Building Insurance, and Common Area Maintenance (CAM) fees.

How Much Does it Cost in New Brunswick?

Securing a commercial space involves significant upfront capital. Beyond the actual rent and deposits, you must budget for professional legal guidance:

  • Lawyer Review Fees: Having a commercial real estate lawyer review and amend your lease generally costs between $1,000 CAD and $3,000 CAD. This is a vital investment to prevent catastrophic hidden costs.
  • Security Deposits: Commercial landlords in New Brunswick typically demand a security deposit equal to anywhere from 1 to 3 months of gross rent before handing over the keys.
  • Tenant Improvements (Build-outs): If the unit is an empty concrete shell, you may need to spend $10,000 CAD to $50,000+ CAD on renovations to make it functional for your specific business.

How Long Does the Process Take?

From the moment you find a suitable property to the day you actually sign the contract, expect the negotiation process to take about 2 to 4 weeks. The landlord’s lawyer and your lawyer will likely need to send the draft back and forth a few times to adjust the liability and repair clauses until both sides are completely satisfied.

Frequently Asked Questions (FAQ)

Are there rent control limits for commercial leases in NB?

No. Commercial leases in New Brunswick are entirely exempt from residential rent control rules. Once your current lease term expires, the landlord has the legal right to increase your rent by any amount they choose, which is why negotiating built-in renewal options is absolutely critical.

Can the landlord evict me immediately if I am late on rent?

Yes, commercial tenancy laws are very harsh. If you miss a rent payment, a commercial landlord can often lock your doors and terminate your lease with very little notice, sometimes within just a few days, depending entirely on the specific default clauses written in your contract.

What happens if I want to sell my business before the lease ends?

You will need a strong “Assignment and Subletting” clause. This allows you to transfer your remaining lease to the person buying your business. However, the lease will almost always state that the landlord must approve the new tenant first, though they cannot “unreasonably withhold” that permission.

Who is responsible for snow removal in a commercial plaza?

This depends entirely on your lease. In a standard Triple Net (NNN) lease in a plaza, the landlord will hire a contractor to plow the snow, but the cost will be passed directly down to you and the other tenants as part of your monthly Common Area Maintenance (CAM) fees.
