New Brunswick Commercial Disclosures: Due Diligence and Rules

Unlike the residential sector, where consumer protection laws mandate the disclosure of specific hazards (like lead paint) prior to lease signing, the commercial real estate market in New Brunswick places the burden of discovery largely on the tenant. Commercial transactions operate under the assumption of "caveat emptor" (buyer/renter beware), making pre-lease disclosures heavily dependent on the negotiation process.

No Statutory "Disclosure Forms"

In New Brunswick, there is no standardized, government-mandated commercial disclosure form that a landlord must hand to a prospective tenant.

Because commercial tenants are legally assumed to be sophisticated business entities making calculated financial decisions, they are entirely responsible for conducting their own deep-dive due diligence before signing a binding multi-year lease.

Key Areas of Negotiated Disclosure

While a landlord is not legally forced to hand over a checklist, tenants will typically demand comprehensive answers and documentation regarding the following critical areas:

1. Environmental Hazards

Environmental liability is the most significant concern in commercial real estate. Tenants—especially those leasing industrial space or retrofitting older buildings—will require landlords to disclose any known environmental issues.

• Phase I & Phase II ESAs: Tenants will commonly request the landlord's most recent Environmental Site Assessments. If a property previously housed a dry cleaner, a gas station, or a manufacturing facility, the tenant will demand full disclosure regarding soil contamination or asbestos.
• Why Landlords Disclose: While not statutorily demanded, failing to disclose known, dangerous environmental defects that make the space unusable for the tenant's intended purpose can lead to claims of misrepresentation, fraud, or breach of contract.

2. Zoning and Permitted Use

The landlord must confirm, or at least disclose to the best of their knowledge, whether the property’s current municipal zoning classification accurately supports the tenant's intended business use.

If a landlord knowingly signs a lease for a heavy manufacturing firm in an area strictly protected for retail zoning without disclosing the limitations, the landlord opens themselves up to significant legal liability once the municipality shuts the tenant down.

3. Structural and Mechanical Systems

In Triple Net (NNN) leases where the tenant assumes responsibility for HVAC maintenance, the tenant will require the landlord to disclose the age, condition, and maintenance history of the existing rooftop units. If the landlord knows the HVAC unit is functionally dead but hides this fact to pass the replacement cost onto a new tenant, it can void the lease under contract law principles of good faith.

Financial Disclosures in Due Diligence

If the commercial lease involves Common Area Maintenance (CAM) fees or significant operating cost pass-throughs, the tenant will demand detailed financial disclosures during negotiation.

A landlord should be prepared to provide:

• The previous 2 to 3 years of audited operating expenses for the building.
• Historical property tax assessments.
• Projected CAM budgets for the upcoming fiscal year.

Building "Good Faith" with Tenants

While New Brunswick law limits statutory requirements, establishing a transparent relationship is a best practice. The smartest commercial landlords proactively disclose known property histories, share recent environmental reports, and allow tenants extended access for independent building inspections. A lease built on complete transparency results in a stronger, less litigious landlord-tenant relationship.
