New Jersey regulates residential landlords more closely than most states, and the duties do not scale down with portfolio size — an owner with one rental carries most of the same obligations as an owner with fifty. The core duties fall into a few buckets: register the property, keep it habitable, pass the required inspections and certifications, handle deposits correctly, screen tenants lawfully, and file proof of insurance.
This is the working manual for those duties, written for owners of 1 to 10 doors, including out-of-state owners managing from a distance.
The implied warranty of habitability
Since Marini v. Ireland (1970), every New Jersey residential lease carries an implied warranty of habitability — no lease clause can waive it. You must deliver and maintain a unit fit to live in: functioning heat, hot and cold water, plumbing, electricity, a sound structure and roof, working locks, freedom from serious hazards, and pest control in multi-unit buildings. If you fail to make a needed repair after notice and a reasonable opportunity, the tenant may repair and deduct the cost from rent — the remedy Marini created — or seek a rent abatement. Habitability is also a defense in a nonpayment case, one more reason to fix problems before they reach a courtroom; see our guide to the NJ eviction process.
Registration: municipal clerk or DCA
Every non-owner-occupied rental must be registered under N.J.S.A. 46:8-27 et seq.:
- One- and two-unit properties register with the clerk of the municipality where the property sits.
- Buildings of three or more units obtain a certificate of registration from the NJ Department of Community Affairs.
The registration identifies the owner, an agent for service of process, and emergency contacts. Give each tenant a copy, update it promptly when anything changes, and treat it as non-optional: a court will not enter an eviction judgment for an unregistered landlord.

Many municipalities require a re-rental inspection or certificate of occupancy at every tenant turnover, some inspect on a fixed cycle, and some require neither — the rule is town-by-town, so verify with your municipality before listing. Separately, buildings of three or more units are inspected by the DCA on a cyclical basis, and every turnover requires a fire-safety certificate covering smoke alarms, carbon monoxide alarms, and a fire extinguisher. The full stack of tenant-facing paperwork is in our guide to NJ landlord disclosures.
Lead-safe certification for pre-1978 rentals
Under P.L. 2021, c.182, rental units built before 1978 must undergo periodic lead-based paint inspections — at tenant turnover, or on a roughly three-year cycle if the same tenant stays — unless the property qualifies for an exemption, such as certification that the unit is lead-free. Depending on your municipality, the inspection is a visual assessment or dust-wipe sampling, performed by the town or a certified private evaluator, and passing yields a lead-safe certification with a limited validity period. Cycles and procedures have been adjusted since the law took effect, so confirm current requirements with your municipality.
Security deposits — and the tenant-damage line
New Jersey caps deposits at 1.5 months' rent, requires them to sit in a New Jersey interest-bearing account with written notice to the tenant, and requires return with an itemized statement within 30 days of move-out — with double damages for wrongful withholding. The full mechanics are in our security deposit guide. Keep the line clear: normal wear and tear and building-system failures are the landlord's cost under the warranty of habitability; damage beyond normal wear caused by the tenant is properly deductible. Dated move-in and move-out photos and a signed condition checklist are what make that line defensible.
Fair housing, including source of income
The federal Fair Housing Act and the NJ Law Against Discrimination both apply, and the state law reaches further — covering, among other categories, marital status, sexual orientation, gender identity, and lawful source of income. That last one matters daily: you cannot refuse an applicant because they pay with a Section 8 voucher or other rental assistance, and "No Section 8" in a listing is itself a violation. Apply the same written screening criteria to every applicant, keep records of decisions, and make sure anyone showing the unit on your behalf follows the same rules.
Liability insurance registration
Under P.L. 2022, c.92, New Jersey rental property owners must maintain liability insurance of at least $500,000 per occurrence — reduced to $300,000 for owner-occupied multifamily properties of four or fewer units — and register the certificate of insurance with the municipality annually, typically with a small filing fee. Municipalities can fine owners who fail to register. Ask your insurer for the certificate and confirm the filing procedure with your municipal clerk.
Frequently asked questions
Do I have to register if I own just one rental?
Yes, if you do not live in the building. One- and two-unit non-owner-occupied rentals register with the municipal clerk; buildings of three or more units register with the DCA. Without registration you cannot obtain an eviction judgment.
Can I decline an applicant who pays with a Section 8 voucher?
No. Lawful source of income is a protected category under the NJ Law Against Discrimination. You may apply your normal, uniformly applied screening criteria, but you may not reject an application because it relies on a voucher, or advertise a unit as unavailable to voucher holders.
Is the tenant ever responsible for repairs?
Tenants are responsible for damage they or their guests cause beyond normal wear and tear. Everything required to keep the unit habitable — heat, water, structure, systems — remains the landlord's duty. If keeping up with these obligations from a distance is the hard part, that is the job a property manager exists to do.
