01
Building policy is not a blanket city law
Wet-over-dry can refer to property or board policy and should not be described as a universal New York City law. Distinguish building requirements from any applicable filing or code determination.

Mixed-Use Wet-Area Feasibility
Wet-over-dry is a building-policy question, not a blanket city law. For mixed-use properties, clarify the current building policy, proposed scope and responsible professional review; applicability depends on the actual building and project.
Building-specific reference
Review property policy and wet-area scope
02
Confirm whether wet-area scope is present
First identify whether the commercial or mixed-use project actually proposes changes to plumbing, fixtures, drainage or related systems. Do not infer scope from a general interior-planning request.
03
Check the governing property documents
Use current property documents and written requirements supplied by the owner or authorized building contact. Rules and policies can differ by property.
04
Assign professional determinations
The responsible design professional and applicable agency determine what technical, permit or filing review is required. This page does not interpret plans or make a legal, code or permit determination.
