New Jersey Commercial Disclosures: Environmental & Zoning Due Diligence

Unlike residential properties—where NJ mandates an extensive list of disclosures (Truth in Renting, Flood Risk, Lead Paint, Window Guards)—the commercial real estate landscape places the burden of due diligence squarely on the tenant under the doctrine of caveat emptor.

Environmental Liability (ISRA)

New Jersey's Industrial Site Recovery Act (ISRA) is one of the most stringent environmental cleanup laws in the nation. Under ISRA, certain categories of commercial and industrial businesses are required to conduct environmental investigation and remediation before closing, transferring, or ceasing operations at a site.

This means a commercial tenant must be acutely aware of:

• Whether the property is subject to ISRA's mandatory cleanup requirements.
• Whether any prior ISRA case is pending or unresolved on the property.
• Reciprocal indemnification clauses in the lease to allocate cleanup liability.

A tenant operating on contaminated land can be held liable for multi-million dollar cleanups under both state and federal (CERCLA) law, even if they did not cause the contamination.

Zoning and Permitted Use

It is entirely the tenant's responsibility to verify that the property is zoned for their intended business purpose.

• NJ municipal zoning laws are enforced at the local level and can be highly restrictive.
• Sophisticated tenants negotiate a "contingency" clause allowing them to terminate the lease if they cannot obtain the required use-and-occupancy permits.

Americans with Disabilities Act (ADA)

Compliance with the ADA is heavily negotiated in NJ commercial leases. The lease must allocate financial and structural responsibility for bringing the property into ADA compliance. In NNN leases, this burden is frequently shifted to the tenant.
