Revise nomination materials as necessary with the assistance of OAHP.
Attend a State Review Board meeting. Properties recommended for listing are forwarded to the Keeper of the National Register, or in the case of State Register nominations, to the Board of the Colorado Historical Society.
Receive notification of listing. (Only properties which meet the criteria for significance and physical integrity are approved for listing.)
A complete annotated listing of the more than 1,700 archaeological and historic sites, buildings, and districts in Colorado currently listed in the State and National registers. Print version updated through January 10, 2008.
A guide to non-regulatory standards and technical advice about archaeological and historic preservation activities and methods. Includes professional qualification standards. Intended for use by professionals in the preservation and archaeological fields.
Find out if OAHP has any information on a particular building or site?
Our office maintains a database of thousands of records on historic and prehistoric resources around the state. Call our office at 303-866-3392 with a name, address or legal location to find out if we have any information. Another possible source of information may be the local historic preservation commissions around Colorado as they maintain their own records.
Find all Colorado properties listed on the National & State Registers?
Both State and National register nomination forms are located under the National & State Register section. Nomination deadlines are located under the National & State Register section.
Find out if there are any restrictions if I list my property?
There are no restrictions imposed by the National or State Register as to what private property owners may or may not do with their property. Private property owners may alter or demolish a listed property subject only to applicable local government regulations and permitting procedures.
Find out information about property insurance for National & State Register listed properties?
Listing, either individually or as a contributing resource in a registered historic district, should have no bearing on insurance coverage. Owning a property listed in the National or State Register does not impose a regulatory burden on the property owner. When making repairs to a listed property that may involve an insurance claim, the property owner is under no obligation to make the repairs following accepted historic preservation standards or guidelines, such as the Secretary of Interior’s Standards for the Treatment of Historic Properties. For more information see: Memo from Office of Archaeology and Historic Preservation dated June 30, 2015 regarding insurance coverage of privately owned properties listed in the National and/or State Register.
Order a plaque for my listed property?
If you are interested in obtaining a plaque recognizing your property's official designation, there are a number of sources from which to order.
History Colorado does not have a standard State Register marker program. You may design and order any type of marker which best fits your needs. We do request that you use a standard statement to indicate the official designation as part of the marker. The standard wording is:
This property has been placed on the Colorado State Register of Historic Properties by History Colorado
History Colorado and the State Historic Preservation Officer do not endorse any suppliers nor can we guarantee the prices or descriptions quoted. We supply plaque sources as a service to you.
The Office of Archaeology and Historic Preservation distributes information to all sectors of society about the importance of properly preserving our significant buildings, sites, structures, and objects. This guidance ranges from scholarly context studies that aid in the evaluation of properties, to brief how-to brochures, to verbatim copies of laws.
In public meetings held as part of the Society’s long-range planning process, educational products and services emerged as the number-one priority requested of OAHP by the public. Making written materials more readily available is one way of improving the delivery of service to Colorado citizens.
Many publications may be read online or may be downloaded for future use. All publications may be ordered via mail, e-mail, phone or FAX. Longer documents, most of which are photocopied, have fees assigned to cover costs of printing and mailing. Short items are free in limited quantities; requests for more than five short items have a charge assessed, except that single copies of forms and their accompanying instruction manuals are always free. All charges shown include mailing, and a 20 percent discount is available to those who pick up materials in person.

The following information is a general guide to sources of funding for preservation projects that assist in the acquisition, restoration, rehabilitation, education, promotion and protection of Colorado's important cultural resources. This information is intended to be a tool from which to begin your search for funding. We recommend that you consult with your local and regionally based preservation organizations for additional funding programs in your community. This is not a complete list.
Access the Office of Archaeology & Historic Preservation (OAHP) cultural resource files?
Unfortunately not all of the Colorado Office of Archaeology and Historic Preservation records are available to everyone. Please refer to our policies and procedures (PDF) for more information.
Although OAHP restricts access to various types of cultural resource data, we also recognize the need to use this information. It is the intent of the policies and procedures to responsibly control and document access without impeding the appropriate use of the files, therefore:
The File Access Request form must be completed whenever cultural resource files are accessed. This includes site/property forms, documents, maps, and images of any kind. If you are planning to visit OAHP to do research we strongly encourage you to complete the File Access Request form available in fillable PDF format and send it to us prior to your visit. This will allow the staff, when possible, to have the requested materials ready for you when you arrive. You can:
mail it (History Colorado Center, Office of Archaeology and Historic Preservation, 1200 Broadway, Denver, CO 80203)
You can also complete the form while at the office.
OAHP staff will pull the appropriate information for the visitor. The files are not accessible to non-staff.
Individuals requesting restricted materials who are not known by the OAHP staff may need to submit qualifications in advance for our review. If you have new staff who will be visiting the office please contact us prior to their visit.
Please let us know if you have any questions or comments.
The Federal Historic Preservation Tax Incentives program is a program administered by the National Park Service and the Internal Revenue Service in partnership with State Historic Preservation Offices. It is a successful and cost-effective Federal community revitalization program dedicated to preserving historic buildings, stimulating private investment, creating jobs, and revitalizing communities. It has leveraged over $62 billion in private investment to preserve and reuse 38,000 historic properties since 1978.

In 1979, the Department of the Interior created a list of ten rehabilitation “Standards” to help ensure that rehabilitation projects protected historic materials, architectural character, and archaeological resources. These Standards are now used nationwide by federal, state, and local governments, as well as by the private sector.
A property shall be used for its historic purpose or be placed in a new use that requires minimal change to the defining characteristics of the building and its site and environment.
The historic character of a property shall be retained and preserved. The removal of historic materials or alteration of features and spaces that characterize a property shall be avoided.
Each property shall be recognized as a physical record of its time, place, and use. Changes that create a false sense of historical development, such as adding conjectural features or architectural elements from other buildings, shall not be undertaken.
Most properties change over time; those changes that have acquired historic significance in their own right shall be retained and preserved.
Distinctive features, finishes, and construction techniques or examples of craftsmanship that characterize a historic property shall be preserved.
Deteriorated historic features shall be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature shall match the old in design, color, texture, and other visual qualities and, where possible, materials.
Replacement of missing features shall be substantiated by documentary, physical, or pictorial evidence.
Chemical or physical treatments, such as sandblasting, that cause damage to historic materials shall not be used. The surface cleaning of structures, if appropriate, shall be undertaken using the gentlest means possible.
Significant archeological resources affected by a project shall be protected and preserved. If such resources must be disturbed, mitigation measures shall be undertaken.
New additions, exterior alterations, or related new construction shall not destroy historic materials that characterize the property. The new work shall be differentiated from the old and shall be compatible with the massing, size, scale, and architectural features to protect the historic integrity of the property and its environment.
New additions and adjacent or related new construction shall be undertaken in such a manner that if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired.
