Mercer County is one of New Jersey’s most intellectually and economically significant counties, home to both the state capital and one of the world’s great universities. Trenton, the county seat and New Jersey’s capital city, anchors the county’s urban core with state government employment, a significant public sector workforce, and one of New Jersey’s most economically challenged urban populations. Princeton Borough and Princeton Township (now merged as Princeton), located in the county’s center, host Princeton University — consistently ranked among the world’s top universities — and a constellation of research, financial, and biotechnology institutions that make the Princeton corridor one of the most significant knowledge economy concentrations in the United States. Between these poles lie Hamilton Township, Ewing, Lawrence, West Windsor, and Hopewell, a range of suburban communities serving the county’s diverse working and professional population.
Mercer County’s rental market reflects this economic diversity. Trenton has an active rent control ordinance and one of New Jersey’s highest eviction rates. Princeton commands the state’s highest rents outside of Hudson County, driven by university demand and a global research economy. Hamilton and Ewing serve state government workers, healthcare employees, and the working class at mid-range rents. West Windsor attracts Princeton corridor professionals and NYC commuters via NJ Transit. No other Mercer County municipality has rent control. The Anti-Eviction Act applies countywide. LLC and corporate landlords must retain NJ counsel for all Special Civil Part proceedings.

Mercer County — Local Rules & New Jersey State Law Highlights
Topic
Rule / Notes
Anti-Eviction Act (N.J.S.A. 2A:18-61.1)
Applies to all residential tenancies in Mercer County. No-cause evictions are prohibited. Good cause must be one of 16 enumerated grounds. Mercer County’s Special Civil Part at 175 S. Broad Street in Trenton handles a significant caseload, with Trenton generating the majority of volume. Legal Services of New Jersey actively serves Trenton and surrounding lower-income communities.
Landlord Registration — CRITICAL
All Mercer County landlords must register with the applicable municipality. Buildings with 3+ units must also register with the NJ DCA. Failure to register is a complete defense to eviction. Trenton verifies registration at landlord-tenant hearings. Confirm current registration status for each property before filing any eviction action.
Corporate/LLC Attorney Requirement
Business entity landlords must be represented by a licensed NJ attorney in all Special Civil Part proceedings (NJ Court Rule 6:10). Non-attorney appearances result in immediate dismissal. Retain NJ counsel for any eviction involving a business entity landlord.
Trenton Rent Control
Trenton has an active Rent Control Ordinance covering most residential rental units. Landlords must register with the Trenton Rent Control Board and comply with annual increase limitations. Trenton’s large low-income and working-class tenant population includes many long-tenured renters with strong Anti-Eviction Act protections. Legal Services of New Jersey is active in Trenton; contested evictions are common. Verify rent control registration and allowable increases before any rent action. Noncompliance is aggressively raised as a defense.
Princeton — University Rental Market
Princeton is Mercer County’s most expensive rental market, driven by Princeton University’s demand for housing for graduate students, postdoctoral researchers, faculty, and visiting scholars, as well as the surrounding knowledge economy of financial firms, biotechnology companies, and research institutions. No rent control in Princeton municipality. Rents rival Manhattan’s outer neighborhoods for well-located units. Screen for verified university affiliation or corporate research employment. Demand is consistent and year-round; vacancy rates are very low. Princeton tenants are typically highly educated, internationally diverse, and financially stable.
State Government Employment — Trenton Corridor
New Jersey state government employs thousands of workers in Trenton and surrounding communities — the State House complex, NJ Department of Labor, NJ Department of Transportation, judiciary, and dozens of state agencies are primary employers. State employees are a stable tenant segment: defined employment, consistent paychecks, and benefit packages that include pension contributions. Screen for verified state employment; civil service employees have strong employment protections. Hamilton Township and Ewing attract many state government workers who prefer suburban living to Trenton itself.
West Windsor — Princeton Corridor Suburb
West Windsor Township has become one of Mercer County’s most desirable suburban communities, driven by its proximity to Princeton, excellent schools, and NJ Transit Princeton Junction station — the county’s best rail connection to New York Penn Station. No rent control. Tenants are predominantly Princeton University affiliates, pharmaceutical and financial research professionals, and NYC commuters. Premium rents; very low eviction rates; long-tenured professional tenants.
Two-Notice System
For most lease violation grounds, NJ law requires a Notice to Cease followed by a Notice to Quit. Both must specifically describe the violation. Nonpayment requires no pre-filing notice. Defective notices result in dismissal in Mercer County’s court. In Trenton especially, where Legal Services attorneys will identify and raise every procedural defect, notice compliance is non-negotiable.
Security Deposit Requirements
Maximum 1.5 months’ rent. Separate interest-bearing NJ account required. Written notice of account details within 30 days. Annual interest paid or credited to tenant. Return within 30 days with itemized statement. Wrongful withholding: double damages + attorney’s fees. Princeton’s high rents make security deposit compliance especially financially consequential — double damages on a $6,000 deposit creates $12,000 exposure plus attorney’s fees.
Source of Income Protection
N.J.S.A. 10:5-1 prohibits refusal to rent based on lawful income source including Section 8/HCV, public assistance, Social Security, and veterans benefits. Mercer County Housing Authority administers HCV programs. Trenton’s large low-income population means a significant HCV presence. Civil penalties up to $10,000 plus compensatory damages and attorney’s fees for violations.
Mercer County Special Civil Part
Address: 175 S. Broad St., Trenton, NJ 08650 Phone: (609) 571-4200 Filing Fee: ~$50 (1 defendant) + $5/additional + $7 service Hours: Mon–Fri 8:30 AM–4:30 PM Mercer County’s Special Civil Part handles a substantial caseload driven primarily by Trenton. Legal Services of New Jersey actively serves Trenton tenants. Contested cases are common in Trenton; the Princeton and suburban communities generate far fewer contested matters. Retain NJ counsel for any Trenton eviction action.
Tenant Can Cure?Yes - tenant can pay all rent due plus costs at any time before lockout to dismiss case (NJSA §2A:42-9). After warrant posted: 3 days to pay rent alone; after 4+ days: rent plus landlord costs.
Days to Hearing10-30 days
Days to Writ3-7 days
Total Estimated Timeline45-90 days
Total Estimated Cost$200-$600
⚠️ Watch Out
CRITICAL: No notice required for nonpayment - landlord can file immediately if rent is even one day late (unless landlord has habitually accepted late rent, then 30-day Notice to Pay or Quit required). Anti-Eviction Act requires just cause for ALL evictions - cannot evict without statutory grounds even at lease end. Tenant can pay and stay up until lockout. Business entities must be represented by attorney.
Serve the required notice based on the eviction reason (nonpayment or lease violation).
Wait for the notice period to expire. If tenant cures the issue (where allowed), the process stops.
File an eviction case with the Superior Court - Special Civil Part (Landlord/Tenant Section). Pay the filing fee (~$50-75).
Tenant is served with a summons and has the opportunity to respond.
Attend the court hearing and present your case.
If you prevail, obtain a writ of possession from the court.
Law enforcement executes the writ and removes the tenant if necessary.

Mercer County New Jersey Landlord-Tenant Law: Trenton, Princeton, and the Full Spectrum of New Jersey Renting
If you wanted to design a single New Jersey county that captured the full complexity of the state’s landlord-tenant landscape — from the most legally demanding urban market to the most rarefied academic enclave — you would design Mercer County. Trenton sits at one end of the spectrum: New Jersey’s capital city, economically distressed, with active rent control, one of the state’s highest eviction rates, aggressive legal aid, and a court docket that reflects the profound gap between housing costs and tenant incomes. Princeton sits at the other: a world-class university town with globally competitive rents, a tenant pool that includes Nobel laureates and hedge fund partners, and an eviction rate that approaches zero. Between these poles lie Hamilton, Ewing, Lawrence, West Windsor, and Hopewell — a range of suburban communities that serve the state government, healthcare, and pharmaceutical workforces that make Mercer County’s non-capital economy function.
The Anti-Eviction Act applies uniformly across this entire spectrum. A Princeton graduate student paying $3,500 a month for an apartment near the university has the same statutory protection from no-cause eviction as a Trenton working-class tenant paying $950 a month for an apartment near the State House complex. The good-cause framework does not have a rent threshold. The notice requirements do not vary by neighborhood. The landlord registration requirement applies in Princeton and in Trenton with equal force. What differs is the practical operational environment: in Princeton, the law is a framework within which landlords and tenants negotiate at arm’s length in a premium market; in Trenton, it is the front line of a housing justice battle where procedural compliance can mean the difference between a family staying in its home or facing displacement.
Princeton University and the International Tenant
Princeton University’s global reach creates a landlord experience that is genuinely unique in New Jersey. Graduate students and postdoctoral researchers at Princeton arrive from dozens of countries, many without U.S. credit history, U.S. rental history, or domestic employment documentation. Standard screening tools — credit reports, employment verification letters from U.S. employers, prior landlord references — often do not apply in their standard forms. Landlords in Princeton have adapted their screening to accommodate this reality: university employment offer letters or enrollment confirmations, bank statements showing sufficient liquid assets to cover the lease term, character references from faculty advisors or university housing administrators, and in some cases university lease guarantee programs that backstop individual student leases.
