but there are considerations for exceptions to the criteria and historic districts have influence on some of those exceptions. Usually, the National Register does not list religious structures, moved structures, reconstructed structures, or properties that have achieved significance within the last 50 years. However, if a property falls into one of those categories and are "integral parts of districts that do meet the criteria" then an exception allowing their listing will be made. Historic district listings, like all National Register nominations, can be rejected on the basis of owner disapproval. In the case of historic districts, a majority of owners must object in order to nullify a nomination to the National Register of Historic Places. If such an objection occurred, then the nomination would become a determination of National Register eligibility only. This provision is controviersial because of the presumption that owners who do not file a formal objection support the designation, placing the burden on opponents. State-level Most U.S. state governments have a listing similar to the National Register of Historic Places. State listings can have similar benefits to federal designation, such as granting qualification and tax incentives. In addition, the property can become protected under specific state laws. The laws can be similar or different from the federal guidelines that govern the National Register. A state listing of a historic district on a "State Register of Historic Places," usually by the State Historic Preservation Office, can be an "honorary status," much like the National Register. For example, in Nevada, listing in the State Register places no limits on property owners. In contrast, state law in Tennessee requires that property owners within historic districts follow a strict set of guidelines, from the U.S. Department of Interior, when altering their properties. Though, according to the National Historic Preservation Act of 1966, all states must have a State Historic Preservation Office, not all states must have a "state historic district" designation. As of 2004, for example, the state of North Carolina had no such designation. Local-level Local historic districts usually enjoy the greatest level of protection legally from any threats that may compromise their historic integrity because many land-use decisions are made at the local level. There are more than 2,300 local historic districts in the United States. Local historic districts can be administered at the county or the municipal level; both entities are involved in land use decisions. Local historic
