About Warren County
Warren County is located in the northwestern corner of New Jersey, bordered by the Delaware River to the west and Pennsylvania to the northwest. Warren County Seat is Belvidere, a small historic town that houses the main county administrative offices. Established in 1824 from portions of Sussex County, Warren County includes approximately 363 square miles and serves a population of roughly 109,000 residents as of recent census estimates.
Warren County is characterized by rolling hills, agricultural lands, and portions of the Delaware Water Gap National Recreation Area, making it one of the more rural and scenic counties in New Jersey. Major landmarks include the Delaware Water Gap, Jenny Jump State Forest, and the historic village of Hope, founded by Moravian settlers in 1769. Warren County Courthouse Complex at 413 Second Street in Belvidere houses the County Clerk's office, which maintains vital records, election records, and various county documents.
Warren County Clerk's Office, part of the County Clerk's functions, handles land records, deeds, and mortgages. Property assessments are managed by municipal tax assessors in each of Warren County's 22 municipalities, as New Jersey operates on a township-based assessment system rather than a centralized county assessor. Warren County's economy has traditionally been based on agriculture, quarrying (particularly limestone and slate), and manufacturing, though in recent decades it has seen growth in residential development as people seek more affordable housing while commuting to larger metro areas.
What makes Warren County unique is its combination of preserved farmland, outdoor recreation opportunities, and small-town character while still being within reasonable proximity to major northeastern employment centers.
