Overview
New Jersey does not have specific mold legislation, though the "Mold-Safe Housing Act" has been introduced in the legislature multiple times since 2013. However, tenants are protected by the implied warranty of habitability, established through landmark New Jersey Supreme Court decisions including Marini v. Ireland (1970) and Berzito v. Gambino (1973). This warranty requires landlords to maintain rental properties in a condition fit for human habitation throughout the tenancy. While there are no state-mandated mold exposure limits or disclosure requirements for rental properties, mold that affects habitability may violate this warranty. The Bureau of Housing Inspection enforces habitability standards for multi-family dwellings (three or more units) under the Hotel and Multiple Dwelling Law (N.J.S.A. 55:13A-1 et seq.).

Tenant Rights
Right to Habitable Housing
All tenants in New Jersey have the right to a rental unit that is safe, sanitary, and fit for human habitation. The implied warranty of habitability is automatically part of every residential lease, whether written or oral. Mold that poses health risks or substantially affects livability may violate this warranty.
Right to Request Repairs
Tenants have the right to notify landlords of mold problems and request repairs. Written notice by certified mail, return receipt requested, is strongly recommended as it creates documentation and establishes when the landlord received notice. Landlords must be given a reasonable opportunity to make repairs after receiving proper notice.
Landlord Responsibilities
Maintain Habitable Conditions
Landlords must maintain rental properties in a condition fit for human habitation throughout the tenancy. This includes ensuring adequate weatherproofing, functioning plumbing, proper heating, electrical systems, and addressing conditions like water damage and mold that affect habitability.
Respond Promptly to Repair Requests
Landlords must respond promptly to maintenance requests related to leaks, water damage, or mold concerns. After receiving proper notice, landlords must be given a reasonable opportunity to make repairs, but failure to act can result in tenants exercising self-help remedies.

Remedies Available to Tenants
Rent Withholding
Available: Rent withholding is recognized in New Jersey through the landmark case Berzito v. Gambino (1973). If mold substantially impairs habitability and the landlord fails to act after receiving proper written notice and a reasonable opportunity to repair, tenants may withhold rent as a set-off. However, tenants should save withheld rent in an accessible account, as courts may require payment if the landlord files for eviction. It is advisable to deposit rent with the court clerk in a habitability hearing. Not every defect constitutes a breach; the condition must truly render the premises uninhabitable in the eyes of a reasonable person.
Repair and Deduct
Available: The repair and deduct remedy was established in Marini v. Ireland (1970). Tenants may repair defects in "vital facilities" and deduct the cost from rent if the landlord fails to make repairs after receiving timely and adequate notice and a reasonable opportunity to act. The repair cost must be reasonable in light of the value of the leasehold, and the tenant cannot have caused the deficiency. Written notice by certified mail is required. Vital facilities include toilets, water supply, heat, electricity, and windows.

Mold Risk in New Jersey
Understanding New Jersey's unique climate and environmental factors helps explain why mold can be a significant concern in rental properties.
New Jersey's Humid Subtropical to Continental Climate
New Jersey has a humid subtropical climate in the south and humid continental climate in the north. The state receives 40-50 inches of precipitation annually. The Jersey Shore experiences higher humidity due to Atlantic Ocean influence. Summer humidity frequently exceeds 70% statewide, with coastal areas experiencing elevated humidity year-round.
Coastal and Urban Challenges
New Jersey faces significant mold challenges due to coastal flooding, aging urban housing, and high population density. Hurricane Sandy (2012) caused catastrophic flooding affecting tens of thousands of homes, leading to widespread mold problems. Cities like Newark, Jersey City, and Trenton have older housing stock vulnerable to moisture issues.
Hurricane Sandy Legacy
Hurricane Sandy (2012) caused unprecedented flooding in coastal New Jersey, affecting over 300,000 homes. Many properties developed severe mold problems that persisted for years. Sandy highlighted the need for stronger mold regulations, though the proposed "Mold-Safe Housing Act" has not been enacted.
Multi-Family Housing Regulations
The Bureau of Housing Inspection enforces habitability standards for multi-family dwellings (three or more units) under the Hotel and Multiple Dwelling Law. This provides an enforcement mechanism for mold issues in larger rental buildings that is not available for single-family or duplex rentals.
Common Mold Types in New Jersey
New Jersey's diverse geography from the Shore communities to the Delaware Valley creates varied mold challenges. Coastal flooding from hurricanes (like Sandy in 2012), high humidity, and aging urban housing in Newark, Jersey City, and Camden contribute to widespread mold issues.
Stachybotrys chartarum (Black Mold)
Found in water-damaged New Jersey homes, particularly in flood-prone areas near the shore. Produces mycotoxins causing severe respiratory and neurological symptoms.
Aspergillus
Common throughout New Jersey in humid conditions. Found in HVAC systems, bathrooms, and water-damaged buildings. Can cause aspergillosis.
Cladosporium
Most prevalent airborne mold in New Jersey. Thrives in humid coastal and suburban areas. Major trigger for allergies and asthma.
Penicillium
Common in New Jersey homes with water damage, especially in older urban housing. Grows on wallpaper, carpet, and insulation.
Chaetomium
Frequently found in flood-damaged New Jersey homes, particularly after coastal storms and hurricanes. Produces potentially carcinogenic mycotoxins.
Mold Professional Requirements in New Jersey
Implied Warranty of Habitability
New Jersey recognizes an implied warranty of habitability in all residential leases, established through case law. Under this warranty, landlords have a continuing duty to maintain rental units in a condition fit for human habitation. This includes providing adequate heat (at least 68 degrees during the day and 65 degrees at night between October and May), running hot and cold water, functioning plumbing, electricity, and properly maintained windows. The implied warranty is part of every rental agreement and cannot be waived by the landlord or tenant. Mold conditions that substantially affect habitability may constitute a breach of this warranty, entitling tenants to remedies including rent reduction, repair and deduct, or lease termination.

Can I withhold rent for mold in New Jersey?
Yes, but with caution. Under Berzito v. Gambino, tenants may withhold rent or a portion of rent if mold substantially impairs habitability and the landlord fails to act after proper notice. You should provide written notice, give the landlord reasonable time to repair, and save withheld rent in an accessible account. Courts may require payment if the landlord files for eviction, so consider depositing rent with the court.
