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.

Frequently Asked Questions
▶What are the New Jersey landlord-tenant laws every property owner should know?
New Jersey is widely recognized as one of the most tenant-protective states in the nation. Unlike most states that allow no-cause evictions, NJ requires landlords to prove "good cause" to remove a tenant-even after a lease expires. Coupled with mandatory interest-bearing security deposit accounts, municipal-level rent control in approximately 117 municipalities, and a powerful implied warranty of habitability, managing rental properties in the Garden State demands meticulous legal compliance. This guide covers the essential compliance requirements for property owners and landlords.

The New Jersey eviction process requires landlords to provide written notice to tenants before filing a court action. The type and length of notice depends on the reason for eviction — typically shorter for non-payment of rent and longer for lease violations or no-fault terminations. Self-help evictions (changing locks, removing belongings, shutting off utilities) are illegal in New Jersey. The full court process varies but typically takes several weeks.

New Jersey has specific rules governing how much landlords can charge for security deposits, how deposits must be held, and the deadline for returning deposits after a tenant moves out. Landlords must provide an itemized statement of any deductions made from the deposit. Failure to comply with deposit return deadlines can result in penalties and the forfeiture of the landlord's right to claim deductions.

New Jersey has specific rules governing when and how landlords can increase rent. During a fixed-term lease, rent generally cannot be increased unless the lease explicitly allows it.
