New Jersey Adopts REAL Rules: New Flood and Coastal Regulations Take Effect in 2026
New Jersey has taken a major step toward strengthening flood resilience and climate preparedness. On January 20, 2026, the New Jersey Department of Environmental Protection (NJDEP) formally adopted the Resilient Environments and Landscapes rules, commonly referred to as the REAL Rules. These regulations substantially revise both coastal and inland flood hazard standards and will have wide-ranging implications for development, redevelopment, and infrastructure projects throughout the State.
For owners and developers, the REAL Rules introduce more stringent design requirements while also providing a limited transition period for certain pending applications.
Overview of the REAL Rules
The REAL Rules are intended to modernize New Jersey’s flood hazard framework by accounting for increased flooding risks associated with sea level rise, storm surge, and extreme weather events. The regulations amend existing coastal and flood hazard area rules and apply to a broad range of projects, including residential, commercial, mixed-use, and public infrastructure development. Among other changes, the REAL Rules raise minimum elevation standards, expand regulated areas, and modify permitting thresholds in flood-prone locations.
Increased Elevation Requirements
One of the most consequential changes is the elevation standard for new construction and substantial improvements. Under the REAL Rules, buildings and certain infrastructure located in regulated flood areas must generally be constructed at least four feet above the applicable Federal Emergency Management Agency (FEMA) base flood elevation. This requirement exceeds prior standards and may significantly affect site design, grading, foundation systems, and overall project costs, particularly in coastal communities and low-lying inland areas.
Creation of the Inundation Risk Zone
The REAL Rules also establish a new regulatory area known as the Inundation Risk Zone. This zone is based on projections identifying areas expected to be permanently inundated by tidal waters by the year 2100. Properties within the Inundation Risk Zone may be subject to additional limitations and review requirements, even if they are not currently located within a traditional flood hazard area. This forward-looking approach represents a notable expansion of flood regulation based on anticipated future conditions rather than solely historical flood data.
Transition and “Legacy” Provisions
Recognizing the impact of these changes, the REAL Rules include limited transition provisions for certain pending projects. Applications that are deemed administratively complete within 180 days of adoption, or by July 20, 2026, may be reviewed under the prior, less stringent regulations. For projects currently in planning or early design phases, these legacy provisions may offer an opportunity to proceed under existing standards, provided that permitting milestones are met within the specified timeframe.
Practical Implications for Developers and Owners
The adoption of the REAL Rules is expected to influence project feasibility, timelines, and costs across New Jersey. Key considerations include evaluating whether projects may qualify for legacy treatment, reassessing site constraints in newly regulated areas, and coordinating early with design professionals to address elevated construction requirements. Projects that do not qualify for transitional review will need to account for the enhanced standards at the outset to avoid delays or redesigns later in the permitting process.
Looking Ahead
The REAL Rules reflect a broader regulatory trend toward integrating climate resilience into land use and environmental permitting decisions. As these regulations take effect, early planning and a clear understanding of applicable requirements will be essential for successful project delivery.
