Preservation Long Island is pleased to announce our Local Landmark Law Locator! This new online map application developed by Sarah Kautz, our Preservation Director, provides Long Islanders with an easy way to explore local landmark laws in our region.

This innovative online tool geographically visualizes local landmark law information for Long Island, a region with more than 100 individual municipalities in just two counties (13 towns, 2 cities, 94 incorporated villages). The first preservation tool of its kind developed specifically for Long Island, the map-based interface empowers public users to research local landmark laws in Nassau and Suffolk Counties by addressing the following questions:

  1. Does my municipality have a local landmark law?
  2. What are my local landmark laws and where can I find them in my municipal code? 
  3. Who are my local landmark officials and how do I contact them?

About 1/3 of the 109 local governments located in Nassau and Suffolk Counties have adopted some form of historic preservation law including one city, all 13 towns, and 31 incorporated villages. Is your local government one?

CLICK HERE to enter an address or scroll to any city, town, or incorporated village in Nassau or Suffolk County. Then click on the map to see a pop-up with details about the local landmark law as well as contact information for the local government.

Why are local laws important? Listing on the National and State Registers of Historic Places does not protect historic sites from destruction by their owners. Only local landmark/historic preservation laws can protect historic properties from incompatible alteration and demolition by private owners.

This map is specifically intended to provide information about local landmark laws and contacts for local governments in Nassau and Suffolk Counties, NY. It does not include information about specific landmarks, historic districts, sites, or properties.

Please note: Preservation Long Island’s Local Landmark Law Locator is intended for educational purposes. Users should contact a lawyer or local government official with legal questions or concerns.
