What is a Multiple Property Document Form (MPD)?
The Multiple Property Document Form (MPD) is a document used to nominate individual properties and historic districts that share a similar time period, geographic distribution, historic themes, and importance. For example, property types and topics that could be described in a MPD include one-room school houses in Oregon, influential architects of Oregon, or properties related to the boom-time development of Baker City. A MPD also identifies what qualities identified resources must possess to be eligible for the National Register under a MPD. Limitations under a MPD could include a time period or geographic area, or specify that properties must retain certain physical characteristics, among other qualifications. While a MPD is not a National Register nomination itself, preparers can use a MPD as a guide to write individual nominations for selected properties that meet the MPD qualifications. Together, a MPD and one or more accompanying National Register nominations are called a Multiple Property Submission (MPS).
Although a MPD is more difficult and time consuming to prepare than a National Register nomination for a single property or historic district, there are several advantages to using a MPD. For example, once a MPD is created, it is often easier to nominate qualifying resources. Properties that would not be individually eligible for the National Register can sometimes be listed under a MPD as well. Existing MPDs are also easier to expand to include new types of resources, as long as these new properties share a similar history to those already listed.
Writing a MPD requires specialized knowledge of historic properties and the geographic area where these resources are found. Generally, only historic preservation professionals should attempt to complete a MPD. Those interested in using an existing MPD, or creating a new MPD, should contact the SHPO prior to beginning work.

Is it Eligible?
Several MPDs already exist for Oregon properties. Since it is often easier to nominate a property or historic district under a MPD, check to see if your property would qualify for listing under an MPD before beginning a National Register nomination. A complete list of Oregon MPDs is available online through the National Park Service's National Register Information System.
Before beginning a National Register project, please submit a Historic Resource Record (HRR) to the SHPO. The HRR asks those interested in listing a property to briefly describe the resource and why they believe it is eligible for the National Register, as well as submit exterior and interior photographs of the resource. If you're interested in using an existing MPD, please note which MPD you believe applies to your building. HRRs can be submitted in person, by mail, or email. SHPO staff will answer these requests within two to four weeks, often sooner.
Using standards established by the National Park Service and information provided in the HRR, SHPO staff will give their opinion on the property's eligibility for the National Register, and give advice on potential research strategies. SHPO staff will also include useful information about the National Register and how to complete a nomination form in the PEE response.

What Does Listing Mean?
The SHPO and the federal government do not regulate private property unless the owner chooses to take advantage of federal and state tax incentives or grants. Local county and city governments, however, are required by state law to protect properties listed in the National Register. Because local laws vary from place to place, property owners or those looking to purchase properties listed in the National Register should contact their local planning office.

Completing the Multiple Property Documentation Form

The National Register nomination is a federal document that has specific technical requirements. Nominating a property under a MPD, therefore, can be complex and difficult. Please contact the SHPO before beginning research on a MPD project. While SHPO staff can assist preparers in completing nominations, staff do not write nominations for preparers.
Proper documentation for a Multiple Property Submission (MPS) includes a correctly completed Multiple Property Documentation Form, if not already using an existing cover document; and at least one completed National Register nomination for a resource that meets the eligibility qualifications as identified in the MPD. All documentation must meet requirements specified by the National Park Service and the Oregon SHPO.
The following documents and guides include all necessary instructions for completing a MPD and National Register nomination. Please note that the example nomination in National Register Bulletin 16A, "How to Complete the National Register Registration Form," is outdated and does not meet current National Register standards. Please contact the SHPO if you would like a current example nomination.
