ADU Rules in Toms River, New Jersey

Toms River Township is the Ocean County seat, located along the western shore of Barnegat Bay with a population of approximately 100,000. The township serves as the mainland hub for Long Beach Island (LBI) — a separate barrier island municipality — and is a central community for the Jersey Shore region. Toms River's unique geography places it at the intersection of multiple regulatory overlays: the Barnegat Bay estuary, the Pinelands National Reserve, the CAFRA coastal zone, and FEMA post-Sandy flood zones.

New Jersey ADU Act and Mount Laurel Context

New Jersey's P.L. 2021, c. 182 (the "Accessory Dwelling Unit Act") provides a statewide framework for ADU development. Toms River Township, like all NJ municipalities, is subject to the Mount Laurel doctrine requiring municipalities to affirmatively provide their fair share of affordable housing. As Ocean County's most populous municipality, Toms River's housing obligations are significant, and ADUs may play a role in meeting those requirements.

Toms River Zoning and ADU Regulations

Toms River Township encompasses a wide variety of residential neighborhoods: established single-family residential areas, modest shore cottages, retirement communities, and newer suburban subdivisions. The township's zoning code reflects this diversity with multiple residential district classifications.

In single-family zones, ADU options may include:

  • Detached ADUs (backyard cottages): Subject to setback compliance and accessory structure size limits
  • Attached ADUs: Additions connected to the main dwelling
  • Garage conversions: Converting attached or detached garages to living space
  • Basement conversions: Only feasible outside FEMA-mapped flood zones

All construction must comply with the NJ Uniform Construction Code (UCC). The township may require owner-occupancy and impose maximum ADU size limits.

Post-Sandy Flood Zones

Hurricane Sandy (October 2012) caused catastrophic flooding in Toms River and neighboring Ocean County shore communities. Much of the bayfront and areas near tidal waterways were severely damaged. Following Sandy, FEMA remapped significant portions of Ocean County, placing many properties in AE or VE (coastal high hazard) flood zones.

Requirements for construction in FEMA flood zones:

  • AE zones: Construction must meet Base Flood Elevation (BFE) requirements; elevation certificate required
  • VE zones (coastal high hazard): Even more restrictive; structures must be elevated on open foundations (pilings or breakaway walls); basement space is prohibited
  • Post-Sandy regulations: Ocean County and many Shore municipalities adopted additional freeboard requirements (building 1–2 feet above BFE) as a precautionary measure

Shore-area properties where ADUs might be in detached cottages or coastal accessory structures face particularly complex elevation requirements.

Pinelands Commission Jurisdiction

Portions of Toms River Township fall within the New Jersey Pinelands Area under the Pinelands Protection Act (N.J.S.A. 13:18A-1 et seq.). The Pinelands Commission (headquartered in New Lisbon, NJ) reviews development in the Pinelands Area and has authority to approve or deny development that would be inconsistent with Pinelands standards.

If your property is in the Pinelands Area:

  • A Pinelands Certificate of Filing is required before local permits are issued
  • Pinelands development standards govern density, impervious coverage, and water resource protection
  • The Pinelands Preservation Area (the most restricted zone) permits only very limited development

Use the Pinelands Commission interactive map or contact them directly to confirm your property's status before planning any construction.

CAFRA Zone

Toms River's Barnegat Bay shoreline is within the CAFRA (Coastal Area Facility Review Act) zone. Development that exceeds CAFRA thresholds requires a permit from the NJ Department of Environmental Protection. Contact NJDEP at (609) 984-9088 or check the online CAFRA mapping tool to determine whether your project requires a CAFRA permit.
