New Jersey Commercial Maintenance: NNN Leases & Property Taxes

Under N.J.S.A. 25:1-12, commercial leases for terms longer than three years must be in writing to be enforceable. While the residential implied warranty of habitability does not apply, New Jersey common law recognizes an implied warranty of suitability against latent defects (Reste Realty Corp. v. Cooper). Furthermore, under N.J.S.A. 46:8-6 and 46:8-7, landlords are statutorily required to repair or rebuild in the event of fire or casualty unless the lease explicitly states otherwise.

The Lease Dictates All Maintenance

If the HVAC system fails in January or the roof leaks, the responsible party is determined primarily by the lease, subject to statutory exceptions for fire or casualty damage. Courts in the Superior Court of New Jersey strictly enforce these contractual allocations of risk.

Triple Net (NNN) Leases

In NNN leases, the tenant is responsible for 100% of maintenance and repair costs, including their pro-rata share of the building's exterior. Given New Jersey's notoriously high property taxes-among the highest in the nation-the tax pass-through component of a NNN lease alone can represent a substantial annual cost increase for tenants.

Gross Leases

More common in multi-tenant office buildings. The tenant pays a single, higher flat rate, and the landlord covers structural repairs, common area maintenance, taxes, and insurance.

HVAC Maintenance Contracts

NJ commercial leases frequently contain specific HVAC clauses. A standard clause requires the tenant to maintain an active preventive maintenance contract with a licensed, landlord-approved HVAC contractor. Failure to produce this contract upon request makes the tenant solely liable for catastrophic HVAC failures.

End-of-Lease "Make Good" Provisions

A rigorous NJ commercial lease will include a "Make Good" or "Surrender" clause requiring the tenant to demolish custom build-outs and restore the premises back to its original condition. If the tenant fails to restore, the landlord may pursue damages for waste or breach of contract in the Superior Court of New Jersey, Law Division.

Official Law Citation: Maintenance obligations are primarily contractual, but N.J.S.A. 46:8-6 mandates landlord repairs for fire/casualty damage. Additionally, Reste Realty Corp. v. Cooper establishes an implied warranty of suitability against latent defects in commercial tenancies.
