Do you need a permit for Water Heater in Westchester County?
In New York, a Water Heater requires a plumbing permit.
Replacing a water heater requires a plumbing permit and inspection; even a same-fuel, same-size swap generally needs one, with the T&P valve, drain pan, and expansion tank checked. Switching fuel type, relocating the tank, or going tankless also triggers gas or electrical permits. Plans are reviewed under the Statewide (exc. NYC) code (IRC 2024); apply through White Plains Building Department / Planning Department before work begins.

HOA & Historic District Approvals
In highly urbanized counties like Westchester County, municipal bureaucracy is only the first step. You will almost certainly need written approval from your Homeowners Association (HOA) before applying for a city permit. Additionally, if you live in a designated historic district, the local architectural committee holds veto power over your Water Heater.
Zoning & Cost Factors
New York has a unified State Fire Prevention and Building Code, but zoning is strictly managed by local municipalities, leading to notoriously complex approvals in NYC. Fortunately, New York maintains relatively builder-friendly regulations, keeping base permit fees competitive.
