Piscataway, NJ Rental Property Rules: Rent Increase Notice (2026)

Section 16-2.3 requires any landlord seeking a rent increase to notify the tenant by certified mail of the calculations behind the increase: the Consumer Price Index at the date the lease was entered into, the Consumer Price Index 60 days before the lease's expiration, the allowable percentage increase, and the allowable rental increase in dollars. That notice duty is backed by § 16-2.2, which voids any rental increase imposed at a time other than the expiration of a lease or termination of a periodic lease, and separately voids any increase that exceeds what Chapter 16 authorizes.

The cap itself comes from § 16-2.1: no landlord may request or receive a percentage increase greater than the lesser of the average Consumer Price Index over the prior twelve months or 6% of the rent then in effect, and a month-to-month tenant cannot be made to pay more than one rent increase in any calendar year. Because § 16-2.3's notice must show the CPI figures used to compute the increase, a tenant can check the landlord's math against the same 6% and CPI-average cap set in § 16-2.1 before the increase takes effect.

The chapter reaches dwellings and housing space rented or offered for rent in the Township, as defined in § 16-1, with the usual carve-outs for hotels, motels and buildings of two units or fewer.
