The 2025 NYC Energy Code is the current adopted framework for many new and altered buildings. DOB began enforcing the 2025 NYCECC and 2025 NYC ASHRAE 90.1 on March 30, 2026.
The filing and energy submission history matters. Complete earlier energy submissions can remain under the 2020 code when DOB transition conditions are satisfied, while incomplete submissions or material compliance changes may trigger the 2025 code.
A useful starting point is to review the work or facility type, the controlling rules and the documents already available. See all Energy Code topics for a broader comparison of the subject.

The review should start with a practical question: determine whether the work is new construction, an addition, alteration or other regulated scope. Relevant records and professional advice may change how the team addresses that question. One common error is assuming a job number created before March 30 automatically preserves the 2020 code. Each decision should be tied to the specific project facts.
Whether this topic calls for a formal filing, field review or further professional advice depends on existing conditions and applicable rules. Keep the records and responsibilities of each regulator separate.
SLK Buildings supports record organization and project coordination; regulated professional work and legal determinations remain with appropriately qualified providers.
Confirm the current code edition, permit classification, available energy analysis and signed drawing set. Check whether new construction, work at an existing building, trade coordination or required inspections change the next step. A report should never be treated as a substitute for current approved plans.
When a design or field condition changes, the responsible professionals should assess whether the energy analysis, supporting documents, progress inspections or sign-off package must be updated. Agency acceptance and professional certifications should be confirmed in the project record.
