New Jersey landlord guide — Anti-Eviction Act, Special Civil Part, Delaware Water Gap & NJ’s most rural western county
📍 County Seat: Belvidere (~2,700) • Delaware River • I-78 corridor • Pennsylvania border 👥 Pop. ~110,000 — NJ’s western-most county — no rent control anywhere ⚖️ Special Civil Part • 413 Second St., Belvidere 🌊 Phillipsburg • Washington • Hackettstown • Blairstown • Hope • Delaware Water Gap
Warren County sits at New Jersey’s westernmost edge, a largely rural and agricultural county that borders Pennsylvania along the Delaware River and reaches northward to the Delaware Water Gap National Recreation Area, one of the most visited recreational areas in the northeastern United States. The county seat is Belvidere, a remarkably small borough of approximately 2,700 that is nonetheless the county’s governmental center and home to the county courthouse. The county’s largest community is Phillipsburg, a former industrial river town of approximately 14,000 that sits directly across the Delaware from Easton, Pennsylvania, and has been working to redefine its economic identity following the decline of the steel and industrial base that historically anchored it. Hackettstown, home to M&M Mars’s manufacturing operations and Centenary University, is another significant community. Washington Borough and Washington Township provide suburban character in the county’s central corridor along I-78.
Warren County’s rental market is small and rural, with rents among the more affordable in New Jersey. The county’s proximity to Pennsylvania — and particularly to the Lehigh Valley metropolitan area anchored by Allentown, Bethlehem, and Easton — means that some Warren County tenants work in Pennsylvania and commute across the Delaware River, creating a cross-border commuter dynamic that is distinct from the NYC-oriented markets that dominate most of New Jersey. No Warren County municipality has local rent control. The Anti-Eviction Act applies countywide. LLC and corporate landlords must retain NJ counsel for all Special Civil Part proceedings. The landlord registration requirement applies in every municipality.

Warren 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 Warren County. No-cause evictions are prohibited. Good cause must be one of 16 enumerated grounds. Warren County’s Special Civil Part at 413 Second Street in Belvidere handles one of New Jersey’s smallest landlord-tenant caseloads, consistent with the county’s small population. The court is accessible and procedures are straightforward for properly documented cases. Legal Services of New Jersey serves qualifying Warren County tenants.
No Local Rent Control
No municipality in Warren County has a local rent control or stabilization ordinance. Landlords may set and raise rents to market rates without local limitation. The Anti-Eviction Act prohibits no-cause evictions regardless of the absence of rent control. Warren County’s relatively modest rents and small population mean that rent disputes are uncommon compared to urban NJ counties, but the state law framework applies with identical force.
Landlord Registration — CRITICAL
All Warren 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. In a county where informal landlord-tenant arrangements are common, registration compliance is frequently overlooked. The court will dismiss for unregistered landlords just as readily here as in any other NJ county. Verify registration 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 regardless of the simplicity of the underlying case.
Phillipsburg — Delaware River Industrial Town
Phillipsburg is Warren County’s largest community and its most urban, sitting directly across the Delaware River from Easton, Pennsylvania. The town’s history as a railroad and steel hub has given way to a more modest economy serving a mix of working-class residents, cross-border commuters who work in the Lehigh Valley, and healthcare workers at St. Luke’s Warren Hospital. Phillipsburg’s rental market is Warren County’s most active and most affordable. Screen for verified employment in healthcare, trades, or services. HCV must be accepted. No rent control.
Pennsylvania Cross-Border Commuters
Warren County’s Delaware River border with Pennsylvania creates a rental market dynamic that is unique in New Jersey. Many Warren County residents, particularly in Phillipsburg, White Township, and the Delaware River corridor, work in the Lehigh Valley (Allentown, Bethlehem, Easton) and commute into Pennsylvania daily. Pennsylvania employment income is fully countable for NJ income-to-rent ratio calculations. Screen PA-employed tenants with the same standards as NJ employees: verified employment letters, recent pay stubs, and income at 3x monthly rent. Warren County tenants working in PA may not have NJ rental history but that does not reflect payment risk — verify PA employer directly.
Hackettstown — M&M Mars & Centenary University
Hackettstown Borough is Warren County’s most economically diverse community, home to the M&M Mars manufacturing facility (one of the county’s largest private employers) and Centenary University (a small liberal arts university). The combination of manufacturing employment and academic presence creates a rental market serving factory workers, university students and staff, and I-78 corridor commuters. Screen for verified Mars, university, or commuter-corridor employment. No rent control. Centenary’s student population is modest but generates consistent demand for housing near campus.
Delaware Water Gap & Rural Recreation
Warren County’s northern reaches border the Delaware Water Gap National Recreation Area, and the county’s rural landscape attracts outdoor recreation visitors and some seasonal or second-home activity. Year-round residential tenants in any Warren County property are fully Anti-Eviction Act-protected. Any genuine seasonal rental under 125 days at a qualifying property type may be exempt — consult NJ counsel before relying on the exemption. Well and septic systems are common in Warren County’s rural and recreation-adjacent properties; habitability obligations apply fully.
Well & Septic Systems
A significant portion of Warren County’s rural rental properties rely on private wells and septic systems. Landlords must provide safe potable water and functioning septic service throughout the tenancy as part of the implied warranty of habitability. Test well water quality before each tenancy. Inspect septic systems before each tenancy. Document all findings and retain records. Address any pre-existing issues before the tenancy begins rather than after.
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 Warren County’s court. Follow procedures precisely regardless of the informality of the landlord-tenant relationship.
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. For rural properties, document all pre-existing conditions including well/septic status at move-in.
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. Warren County Housing Authority administers HCV programs. Civil penalties up to $10,000 plus compensatory damages and attorney’s fees for violations. Pennsylvania-earned income is lawful income and cannot be discriminated against in the rental application process.

⚠️ 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.

Warren County New Jersey Landlord-Tenant Law: The Delaware River, Pennsylvania Commuters, and Renting at the Edge of New Jersey
Warren County is where New Jersey ends at the Delaware River and Pennsylvania begins — and the rental market here reflects that geographic reality in ways that distinguish it from every other county in the state. The Lehigh Valley metropolitan area, anchored by Allentown, Bethlehem, and Easton just across the river, exerts significant economic influence on Warren County’s western communities. Phillipsburg tenants commute into Pennsylvania for work at Lehigh Valley Health Network, Air Products, B. Braun Medical, and dozens of other Lehigh Valley employers. White Township residents cross the bridge into Easton for work. Warren County’s rental market is not oriented toward New York City — it is oriented toward Pennsylvania, a cross-border economic relationship that creates tenant income patterns and employment documentation needs that differ meaningfully from what most New Jersey landlords encounter.
The Anti-Eviction Act does not distinguish between tenants who work in New Jersey and tenants who commute to Pennsylvania. A Phillipsburg tenant employed at a Bethlehem, Pennsylvania hospital has the same Anti-Eviction Act protections as a Hoboken tenant employed at Goldman Sachs. The procedures are identical. The notice requirements are identical. The registration requirement applies equally. The only practical difference in screening is that Pennsylvania employment documentation follows PA conventions rather than NJ ones — but the legal analysis of the tenancy once established is entirely governed by New Jersey law.
Phillipsburg: Warren County’s Rental Center and Its Pennsylvania Connection
Phillipsburg has been economically linked to Easton, Pennsylvania since the two communities grew up on opposite banks of the Delaware River in the nineteenth century. The Warren Bridge connects them at the center of both downtowns. When Phillipsburg’s steel and railroad industries declined, many residents maintained economic connections to the Pennsylvania side where the Lehigh Valley’s more diversified economy provided employment opportunities that persisted through the industrial transitions of the twentieth century. Today, Phillipsburg’s rental market serves a cross-section of working-class residents, healthcare workers at St. Luke’s Warren Hospital, cross-bridge commuters, and lower-income tenants receiving public assistance — a combination that makes source-of-income compliance particularly important and that produces a Special Civil Part caseload that, while modest, is the most active in Warren County.
Landlords screening Phillipsburg applicants who work in Pennsylvania should request the same documentation they would from any applicant: employment verification letter from the Pennsylvania employer, recent pay stubs, and bank statements. Pennsylvania income is lawful income under New Jersey law, and a landlord cannot apply a lower standard to PA-employed applicants than to NJ-employed ones. The 3x income-to-rent calculation applies to total verified income regardless of which state it comes from.
