Frequently Asked Questions

Years ago, the State of NJ had a Landlord-Tenant division within one of its many departments, but ultimately dissolved that division, leaving the topic of rent control up to the individual municipalities. Back in 2002, Hamilton Township abolished rent control within the township.  If you visit the township's website, www.hamiltonnj.com, go to "Departments", then go to "Clerk", you will see a selection for "Ordinances Online".  Information on the township's Rent Leveling Commision may be found in § 5-145 through § 5-172 of the Code.

For those who had tenancy prior to 2002, rent control in Hamilton Township applies to:

• Apartment houses with four or more apartment units in one building. Duplexes and condominiums do not qualify.
• Applies to tenants who had tenancy prior to September 1, 2002 in the same apartment complex or home. If tenant took tenancy after September 1, 2002, rent control no longer is applicable to tenant since rent control was abolished in August of 2002.

For tenants who had tenancy prior to September 1, 2002, their rent may only be raised a certain percentage each year, and they must meet the following criteria to qualify:

• They must reside in a building with four or more residential units in that building, owner occupied included.
• Duplexes, condominiums and townhouses do not qualify.

If tenant meets these requirements, the percentage they may be increased each year is called the "Rent Control Consumer Price Index (CPI)". The amount that the rent can be raised is determined by the Current CPI (Consumer Price Index) figures. Figures are taken from a nationwide federal average. The definition of the Consumer Price Index is as follows: it is the measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services (U.S.) Department of Labor). Landlords must use the current figure provided at the time of sending their notices, not the projected figures for when the rent increase actually becomes effective. This figure is calculated every year by the Secretary of the Rent Leveling Commission.

Whether you own an apartment complex or rent a room in your home, the Township requires all landlords to be registered (PDF). Failure to register and have your unit inspected will result in monetary fines and penalties.

At the time of registration of a rental unit as required by sec. 66-78(c)(1), and prior to the issuance of a rental unit registration certificate, the landlord or agent thereof must pay a fee in accordance with the following schedule for the purpose of having the rental unit inspected by the township and having the township issue the rental unit registration certificate:

Upon initial registration and following the expiration of every five year period thereafter a fee of $50 shall be assessed, to be collected within 90 days following the passage of this ordinance, which includes an inspection and one subsequent re-inspection (to be completed within 30 days of a failed initial inspection). Multi-unit facilities containing four or more units shall be assessed a fee of $50 per unit collected in equal annual installments over a five year period, with the first payment due within 90 days following the passage of this ordinance. Prepayment of this fee shall not be penalized.

Any change of occupancy, except those changes of occupancies specified during the initial registration or upon each subsequent five year inspection, shall be assessed a fee as required pursuant to section 66-64(c)(d)(f) of this code.

Fees not paid shall be subject to a late fee of $30 per month.

Senior Citizen Exemption

If the owner of the property is a senior citizen who resides in a unit of the property and rents out the remaining unit and would otherwise qualify under the State of New Jersey property tax deduction under NJ.S.A. 54:4-8.41, there shall be no fee.

If the owner of the property is a senior citizen who resides in a unit of the property and rents out the remaining unit and would otherwise qualify under the State of New Jersey property tax deduction under NJ.S.A. 54:4-8.41, there shall be no fee.

(a) It shall be the duty of every person who shall contract, undertake or agree or who shall have contracted, undertaken or agreed, orally or in writing, to heat or to furnish heat for any building within the township occupied as a residence by two or more families to furnish sufficient heat to any occupied part of such building so as to maintain, at all times between the hours of 6 am and 11 pm, a minimum temperature of 68 degrees Fahrenheit and, between the hours of 11 pm and 6 am, a minimum temperature of 65 degrees Fahrenheit. The supply of heat required in this section shall be furnished for or to all buildings or parts thereof used for business or living purposes from October 1 in each year to May 1 of the succeeding year and on all other days of the year when the outside temperature falls below 55 degrees Fahrenheit for any 24-hour period, provided that the requirement of this section shall not apply to buildings or parts thereof used for any trade or business in which high or low temperatures are essential. The term "contracted," as used in this section, shall be construed to mean and include any written or implied contract, lease or letting, and the presence of any heating outlets, radiators, risers or returns in any hall, room or other part of a building shall be prima facie evidence of an implied contract. The presence of any central heating plant, furnace or boiler under the control of the owner, lessee or person in charge of the building shall also be prima facie evidence of an implied contract.
