A more thorough explanation:

HISTORIC-PRESERVATION LAW

Historic-preservation law is a rule that stops people from tearing down or changing the outside of certain old buildings or all buildings in a historic area.

For example, if a building is over 100 years old and is considered a historic landmark, the law may prevent someone from tearing it down or changing the way it looks on the outside. Another example is if a whole neighborhood is considered a historic district, the law may prevent people from making changes to the outside of any building in that area.

One example of a historic-preservation law is the New York City Landmarks Preservation Commission. This commission is responsible for protecting and preserving historic buildings and neighborhoods in New York City. They have designated over 36,000 buildings and sites as landmarks, which means they cannot be demolished or altered without permission from the commission.

Historic-preservation laws are put in place to protect important buildings and areas that have historical significance. By preventing people from tearing down or changing these buildings, we can preserve our history and culture for future generations to enjoy. The examples show how these laws can apply to individual buildings or entire neighborhoods, and how they are enforced by organizations like the New York City Landmarks Preservation Commission.
