This article is about the common types of government restrictions on real estate. The three most common types of restrictions are zoning regulations, environmental hazards, and public easement/right of way. Zoning means that the land may only be used for certain types of things such as residential, industrial, or commercial. You cannot store hazardous materials on property without the proper authority from the government. You have to give people access to their land with easements if your property is the only way for them to get to their land. This would also apply for people walking a beach front or trying to get to a body of water. These restrictions can affect the value of property depending on where it is and what type of zoning it is in. So the government can really hurt your property value if you are not careful.
