New Jersey late fee laws for rent: the five business day grace period and who it covers

What does N.J.S.A. 2A:42-6.1 say?

The statute, as amended by P.L. 2001, c. 142, says a person to whom rent is due and payable on the first of the month upon a lease or other agreement shall allow a period of five business days grace in which the rent due shall be paid. It adds that no delinquency or other late charge shall be made which includes the grace period of five business days.

A business day is any day other than a Saturday, Sunday or State or federal holiday. So the grace period is not five calendar days. A holiday or a weekend stretches it.

Does the grace period protect every tenant?

Not on the text I read. Section 2A:42-6.3 says the provisions of the act apply only to premises rented or leased by senior citizens receiving Social Security Old Age Pensions, Railroad Retirement Pensions or other governmental pensions in lieu of Social Security Old Age Pensions, and by recipients of Social Security Disability Benefits, Supplemental Security Income or benefits under Work First New Jersey.

Many landlord guides describe the five business days as a rule for all tenants. The statute's own limiting section says otherwise. Because an owner may not know which tenants receive these benefits, some owners simply give everyone the five business days in the lease, which is allowed and removes the question.

Does New Jersey cap the late fee amount?

The two sections I read set a timing rule, not an amount. Neither contains a percentage or dollar limit on a late charge. The lease sets the amount, and a modest flat fee that clearly belongs to the lease is easier to defend than a large one. Ask a New Jersey attorney about enforceability limits in your county.

How do you count five business days?

Example a made-up owner has rent due on the 1st, and in this made-up month the 1st falls on a Monday. The five business days that follow are Tuesday the 2nd, Wednesday the 3rd, Thursday the 4th, Friday the 5th and Monday the 8th, so a late charge cannot include any of those days. Had the 5th been a State holiday, the count would end one business day later, on Tuesday the 9th.

Whatever day you pick as the first possible charge, write it in the lease in plain words, such as "a late charge may be added after the fifth business day of the month," and add the holiday rule. Then do the counting once for the whole year in a calendar, not rent by rent.

What should you keep on file?

Keep a simple record in New Jersey of the first business day after each rent due date, since the count starts there. If you give every tenant the five business days in the lease, you can use one calendar for the whole building instead of tracking which tenants receive Social Security, Supplemental Security Income or Work First New Jersey benefits.

How DoorKeeping handles it in New Jersey

DoorKeeping posts only the late fee rule you approved from your lease, as its own line, and sends the tenant a reminder first. Rent and payments stay in your own bank accounts. DoorKeeping never holds your money and sends a payment only when you approve it. This is general information, not legal advice. Confirm your lease and which tenants the grace period covers with your own New Jersey attorney.
