New Jersey landlord rules: late fees, deposits and rent increases

New Jersey doesn't put a number on late fees, but it does cap deposits and requires them to be held in an interest-bearing account. Here is what the New Jersey Statutes say, with the section for each rule.

Late fees in New Jersey

Limit

The statute sets no limit. N.J.S.A. Title 2A, ch. 42; Title 46, ch. 8

Grace period

None for most tenants. Five business days' grace are required for rent due on the 1st, but just for premises rented by senior citizens receiving Social Security or pensions and by people receiving SSDI, SSI, or WFNJ benefits. A violation is a disorderly persons offense. N.J.S.A. 2A:42-6.1, 2A:42-6.3

Other conditions

After a warrant for removal is posted, a late fee can't exceed the amount in the warrant application if the tenant pays within three business days. The statute doesn't say a late fee must be in the lease or be reasonable. N.J.S.A. 2A:42-10.16a(a)

Security deposits in New Jersey

Maximum deposit

One and a half months' rent. Yearly additions to the deposit can't be more than 10% of the current deposit. N.J.S.A. 46:8-21.2

Return deadline

30 days after the lease ends. Return it by personal delivery, or by registered or certified mail. Shorter deadlines apply after displacement by fire or flood and after a domestic violence lease termination. N.J.S.A. 46:8-21.1

Itemized deductions

Required, with the interest, by personal delivery or registered or certified mail. The statute sets no separate deadline for the itemization. No deductions may be made from the deposit of a tenant who stays in the unit. N.J.S.A. 46:8-21.1

Interest

Required. Interest or earnings belong to the tenant. Paid in cash or credited against rent each year, on the lease anniversary or on January 31 if the tenant is given written notice. The rate is whatever the account earns. The statute sets no fixed rate. Seasonal rentals of 125 days or less are excluded. N.J.S.A. 46:8-19

How it's held

In trust, in an insured account in New Jersey or an insured money market fund. No bond is required. Landlords with 10 or more rental units use a money market fund or a New Jersey bank account with a variable rate. Landlords with fewer than 10 units use an interest-bearing New Jersey bank account. The tenant gets written notice of the bank, account type, rate, and amount within 30 days of receipt and each year. The deposit can't be mingled with the landlord's own property. N.J.S.A. 46:8-19

Penalty

Double the amount owed, plus full costs. The court may also award reasonable attorney's fees. Small claims court can hear cases up to $5,000 (N.J.S.A. 46:8-21.4). If the landlord fails to invest the deposit, give the notices, or pay interest, the tenant may apply the deposit plus 7% yearly interest against rent (N.J.S.A. 46:8-19). N.J.S.A. 46:8-21.1

Rent increases in New Jersey

Notice to raise rent

No statute sets a notice period for a rent increase. To evict for nonpayment of an increase, the statute requires a valid notice to quit and notice of the increase. The two checks found different notice-to-quit periods for a month-to-month tenancy, so read the statute or ask a local attorney for the period that fits your lease. N.J.S.A. 2A:18-61.1(f)

Statewide cap

None in the statute for ordinary rentals. An increase can't be unconscionable if the landlord evicts for nonpayment of it. Manufactured home park lots have their own 3.5% limit over 12 months under N.J.S.A. 52:27D-287.13. N.J.S.A. 2A:18-61.1(f)

City rent control

Allowed. State law doesn't ban municipal rent control. New multiple dwellings can be exempt from local rent increase limits for up to 30 years. N.J.S.A. 2A:42-84.2

This page covers New Jersey state law for ordinary residential rentals. Cities and counties can add their own rules, and subsidized housing and mobile home lots follow different ones. The New Jersey Legislature's statute site has no link to a single section, so each citation opens the statutes search page. Search there for the section number. Many New Jersey towns have their own rent control, so check your town too.
