Westchester Permit & Inspection Guide

Which Projects Require a Permit in Westchester?

In most Westchester municipalities, a building permit is required for any work that involves: moving or adding a wall (structural or non-structural), relocating plumbing fixtures (sink, toilet, shower drain), upgrading the electrical panel or adding circuits, installing a range hood that penetrates an exterior wall, adding or modifying HVAC systems, or any addition to the footprint of the home. Cosmetic work — replacing countertops, painting, or installing new flooring without subfloor changes — typically does not require a permit, but this varies by town.

How the Permit Process Works in Westchester Towns

The permit process varies somewhat from town to town, but the general framework is consistent. First, a complete set of drawings is prepared — for a full kitchen remodel, this typically includes floor plans, elevation drawings, and mechanical/electrical layouts. These are submitted to the building department, which may take anywhere from two weeks (in smaller towns like Rye) to four to six weeks (in White Plains or Yonkers) for initial review. Once approved, work can begin, and the building department will schedule inspections at key milestones: framing, rough plumbing, rough electrical, and final.

What Happens During an Inspection?

A building inspector visits the site to verify that work complies with the approved plans and applicable codes. For a kitchen remodel, inspections typically happen three times: a rough inspection after framing, plumbing, and electrical rough-in is complete but walls are open; a mid-project inspection if required; and a final inspection after all work is complete and the space is ready for occupancy. Passing the final inspection results in a certificate of occupancy (CO) or a certificate of compliance, which is what you need to document the permitted work when you eventually sell the home.

Why Unpermitted Work Is a Risk Worth Avoiding

We occasionally hear from homeowners who had a kitchen or bathroom remodeled without permits — often by a contractor who suggested skipping the process to save time or money. The risks are significant: insurance claims for damage related to unpermitted work can be denied, unpermitted work must be disclosed (and often remediated) when selling the home, and the cost of retroactively permitting work that didn't follow code can exceed the original project cost.
