Somerset County, New Jersey Eviction Risk: High

Somerset County carries an average eviction-risk score of 7.3/10 (High) across its 47 cities, placing it in the middle third of New Jersey counties, with 11 of the state's 21 counties scoring higher. For landlords and investors, that average number understates the practical challenge: the county is home to a population of over 281,000, an average rent of $2,126, and a rent-burden rate of 30.5%, a combination that puts meaningful financial pressure on tenants and keeps eviction filings a real operational risk. New Jersey eviction laws's strong tenant-protection framework amplifies that baseline, making it essential to understand how individual submarkets within the county differ before committing capital.

The intra-county spread tells the more important story. Scores range from a low of 5 to a high of 8.6, a gap wide enough that two properties a few miles apart can represent materially different risk profiles. At the lower end, communities like Bradley Gardens (5.8/10) and Martinsville (6.1/10) still carry elevated risk by national standards but compare favorably against the county average. At the upper end, several cities push above 8, meaning landlords there face conditions that rank among the more challenging in an already demanding state.

The cities inside Somerset County

East Franklin tops the county at 8.6/10, the highest single score in the county, followed closely by Belle Mead at 8.3/10. Among the larger population centers, North Plainfield (population 22,809) and Somerville (population 13,410) both score 8.2/10, and Bound Brook (population 12,219) matches them at 8.2/10. These are not fringe communities; North Plainfield eviction risk and Somerville are two of the county's most populated cities, which means the highest-risk conditions apply to a substantial share of the county's rental stock.

The contrast with the lower end of the range reinforces just how hyper-local risk is in Somerset County. Bradley Gardens at 5.8/10 and Martinsville at 6.1/10 land noticeably below the county average, even though they sit within the same county boundaries and are governed by the same state statutes. Investors underwriting a deal in the county should pull city-level scores for every specific location rather than relying on the county figure.

State-level laws that apply here

Every landlord in Somerset County operates under New Jersey state law, specifically N.J.S.A. § 46:8 and N.J.S.A. § 2A:18 (the Anti-Eviction Act). Just-cause eviction is required statewide, meaning a landlord cannot remove a tenant without a qualifying statutory reason. Notice periods vary by cause: nonpayment of rent requires no advance notice before filing under N.J.S.A. 2A:18-61.1(a), disorderly conduct or willful damage requires 3 days, a substantial lease violation requires 30 days, and an owner move-in or substantial renovation requires 60 days. The New Jersey eviction process runs 30 to 60 days for an uncontested case and 90 to 180 days for a contested one, timelines that demand careful cash-flow planning. Source of income is a protected class under New Jersey law, administered by the New Jersey Division on Civil Rights, which limits certain tenant-screening decisions.

New Jersey eviction costs can add up quickly. Court filing fees run $50 to $100, sheriff lockout fees $40 to $150, and attorney fees $750 to $3,500, with the high end applying to contested cases that drag toward the six-month mark. Local municipalities retain the right to enact rent control ordinances since state law does not preempt them, so landlords should verify whether a specific city has local rent regulations in addition to understanding New Jersey security deposit limits and the broader statutory framework before acquiring property here.

Somerset County's poverty rate of 5.9% is relatively low, but with only 27.8% of residents renting, the landlord pool is concentrated, meaning vacancies and tenant quality matter more per unit than in higher-density rental markets.
