Suffolk County, New York Eviction Risk: High

Suffolk County scores 8.2/10 on the EvictionRiskMap eviction-risk index, placing it in the Elevated tier, yet it is actually the least risky of all 60 counties in New York: 59 counties carry higher scores, and none are lower-risk. For landlords comparing submarkets across the state, that distinction matters. The county's average rent of $2,324 per month and a renter cost-burden rate of 34.9% suggest genuine affordability pressure on tenants, which adds friction to collecting consistently, even in this comparatively favorable county.

The intra-county spread runs from 7.4 to 8.9 across 148 individual cities, meaning a landlord's experience can differ substantially depending on which community a property sits in. Operating conditions at the low end of that range feel measurably different from the top, and treating the county average as a single operating reality would be a mistake.

The cities inside Suffolk County

At the riskiest end of the county, Melville and Moriches both reach the county ceiling of 8.9/10, joined by Northampton and Napeague at the same level. Bay Shore (population 31,683) comes in at 8.3/10, as do North Amityville, Riverhead, and Patchogue. These communities combine higher poverty and renter-stress indicators that translate to slower rent collection and elevated eviction likelihood relative to the county average.

Further down the risk spectrum, Commack (population 36,558) scores 8.5/10, and Centereach (population 31,839) matches that figure. These are some of the county's most populous communities and carry meaningfully lower operating risk. The spread underscores that risk in Suffolk County is hyper-local: two properties a few miles apart can fall into very different risk profiles.

State-level laws that apply here

Every landlord in Suffolk County operates under New York eviction laws state law, principally N.Y. RPL § 226 et seq. and RPAPL § 711. Notice requirements vary by situation: a nonpayment case requires a 14-day notice under RPAPL § 711(2); a material lease violation requires only 10 days under RPAPL § 711(1). Holdover notices are tiered by tenancy length, from 30 days for tenancies under one year to 60 days for one to two years and 90 days for tenancies of two years or more, all governed by RPL § 226-c. Understanding the New York eviction process at each stage is essential before serving any notice.

Once a case is filed, court costs run $45 to $210 in filing fees and $50 to $200 for sheriff lockout fees; attorney fees typically add $1,000 to $4,000, making the New York eviction costs for a contested case a significant line item. Uncontested proceedings resolve in 30 to 90 days; contested matters stretch to 90 to 210 days. New York eviction laws requires just cause to evict in most circumstances, source-of-income discrimination is prohibited statewide, and rent regulations vary by locality because the state does not preempt local rent-control ordinances.

Suffolk County's average poverty rate of 6.2% and renter share of 17.4% are among the lower figures in New York, which partly explains the county's position at rank 60 of 60; review the city grid above to identify the specific communities where risk concentrates near the county's 6.4/10 ceiling.
