Terms of use
Last updated .
By using National Historical Register you agree to these terms. They are short on purpose. If you do not agree, please do not use the site.
What this site is
National Historical Register is an independent, privately run guide. It is not affiliated with, endorsed by, or operated on behalf of the National Park Service, the US Department of the Interior, the National Register of Historic Places, or any State Historic Preservation Office.
The site is a reference built from public records. It cannot list a property, remove one, issue a certificate or sell an official plaque, and it does not act for any government body. For official decisions, contact the National Park Service or your State Historic Preservation Office; see Not affiliated.
Information, not advice
Property pages, guides and tools give general information. They are not legal, tax, financial, real-estate or architectural advice. Rules on tax credits, review and local designation change and differ by state and city. Confirm anything that matters with the relevant office or a qualified adviser before you act on it.
Accuracy
Listing facts come from the National Park Service database and are shown with the date they were checked. Property summaries are generated by a language model from the official nomination document and are labelled on every page; they can contain errors, and nomination documents themselves can be decades out of date. Map pins are often approximate, and each page says how its coordinates were obtained. The address lookup searches near a geocoded point and can miss a property or match the wrong one. The site is provided as it is, without any warranty that it is complete, current or free of error. How text is produced and corrected is set out in the editorial policy.
Private property
Most listed properties are privately owned and are not open to the public. A page on this site is not an invitation to visit, enter or photograph a property. Respect owners, posted signs and the law.
Reusing content
- Listing data from the National Park Service is US government information in the public domain.
- Photographs belong to their authors and are used under the free licence shown with each image. To reuse one, follow that licence and credit, not these terms.
- Guides, summaries, page design and the compiled dataset are this site's own work. You may quote short passages with a link to the page. Please do not republish pages in bulk or present the site's text as your own.
- The JSON API is free for reasonable use with attribution and a link. Sources and licences are listed on the data sources page.
Acceptable use
Do not use the site to break the law, to harass or locate private individuals, or to interfere with its operation. Automated access is welcome at a rate that does not degrade the service for others and should respect robots.txt; access that does not may be blocked.
Links, advertising and referrals
Pages link to official sources and other third-party sites that this site does not control and is not responsible for. The site may show advertising and may earn a commission from clearly labelled referral links. Neither affects which properties are covered or what a page says, and no payment is accepted to list, remove or alter a property page. What is collected when you browse is described in the privacy policy.
Liability
To the extent the law allows, the site and its editor are not liable for loss or damage arising from use of, or reliance on, anything published here. Nothing in these terms limits rights that cannot lawfully be limited.
Changes and corrections
These terms may be updated; the date at the top shows the latest revision. To report an error or ask about these terms, see the contact page.
