New York SEQRA Reforms to Impact Future Development Planning
Authored by: Jessica Taylor, PG & Levi Curnutte
Previously known for extending predevelopment reviews by two years or more, New York’s State Environmental Quality Review Act (SEQRA) has finally been reshaped through a sweeping reform. On May 26, 2026, the New York State Legislature adopted amendments to SEQRA by adding new definitions, creating deadlines for certain agency determinations, and establishing new conditions for granting exemptions, including for housing and infrastructure projects. These reforms may create a more predictable path through environmental review for developers and reduce time spent in pre-development.
Eligibility for the new exemptions remains criteria-specific and subject to agency determination; other land use, environmental remediation, and permitting requirements may still apply. Notably, housing projects must be on “previously disturbed land,” as defined by having been substantially altered by a current or previous improvement at least two years before submission of a permit or authorization application.
The reform lays out criteria to exempt certain projects from the state’s SEQRA process if they do not have a significant environmental impact:
- For cities like NYC, with populations of one million or more, housing projects may qualify for the exemption if they are:
- Capped at 250 dwelling units, with a higher cap of up to 500 units available in certain higher-density zoning districts based on building height regulations;
- Located on a “previously disturbed site” (see above definition);
- Not zoned exclusively for industrial uses;
- Capping non-industrial, non-residential uses at 50,000 square feet (including for mixed use).
- For cities with populations of less than one million, housing projects may qualify for the exemption if they are:
-
- Within a range of 20 to 300 dwelling units, with the allowable development dependent on the population of the municipality;
- Located on a “previously disturbed site” (see above definition);
- Capping non-residential uses at the lesser of 50,000 square feet or 20% of gross floor area (including for mixed use); and
- Connected to existing community or public water and sewer systems.
- Even if qualified for exemption, projects must comply with hazardous
What does this mean for developers?
For developers, the reforms may create a more predictable path through environmental review and reduce the time spent in pre-development, but this does not remove the need for early site-specific due diligence.
Additionally, exemptions through SEQRA will not supersede, limit, modify, or affect any authorizations, requirements, or procedures of laws or regulations on, among other things, historic preservation, disadvantaged communities, air & water quality, wetlands, endangered species or zoning. Key considerations include:
- Could the project qualify for a streamlined SEQRA exemption or a “previously disturbed site” designation?
- Are hazardous materials compliance and Phase I ESA certification requirements addressed early enough to support funding, approvals, and/or closing?
- Could subsurface contamination, vapor intrusion, soil management, or remediation issues affect financing, permitting, construction sequencing, or long-term liability?
- Are local zoning, site plan, and special permit requirements still likely to raise environmental or neighborhood-specific concerns?
What can Roux do to help?
Roux helps development teams move from acquisition through construction with practical environmental due diligence and redevelopment support. Our team can complete Phase I ESAs; evaluate hazardous materials and subsurface contamination concerns; assess vapor intrusion and soil management risks; support Brownfield Cleanup Program and remediation strategies; and prepare construction-phase environmental management plans that align with transaction, financing, permitting, and schedule requirements.
As SEQRA implementation evolves, Roux can help developers identify environmental risks early, document compliance with applicable hazardous-materials and Phase I ESA findings, and develop cost-effective strategies to keep acquisitions, approvals, and construction moving forward.
