Feasibility Study

Historic research includes compilation of multiple historic resource documents; including building histories, archaeological resources, previous property owners, as well as the original architect, original contractor, and the history of how the property was designed and constructed.

In accordance with the National Park Service standards, a new addition to a historic property must preserve the building’s historic character, meaning that the addition needs to be different, but compatible with the historic building.

A Preservation Plan for a historic property is a planning tool that provides necessary information to guide the development, prioritization, and implementation of repair, rehabilitation, and restoration projects.

The choice between rehabilitation, restoration or reconstruction depends on the specific project; including, but not limited to the property’s historic significance, physical condition, proposed use, and code requirements.

An extensive survey of the condition of your historic property, which includes reviewing the roof, parapet, windows, doors, exterior sealant, decorative elements, and sidewalks around a property to look for water infiltration or areas of concern for the maintenance of the property.

Owning a historic property can provide income tax credits for the rehabilitation of historic, income-producing buildings that are determined by the Secretary of the Interior, through the National Park Service, to be “certified historic structures”.

The significance of a building or place can be determined by the American history, architecture, archeology, and culture present in districts, sites, buildings, structures, and objects.

To be listed as contributing property on the National Register of Historic Places, the building history needs to be compiled for the property; including building histories, archaeological resources, previous property owners.

Section 106 and 110 are the steps undertaken to get an eligible property listed on the National Register of Historic Places. GH2 can aid in compiling the resources to fill out the forms and provide the required documentation to have your historic property listed as a contributing property.

The Historic American Building Survey (HABS) and Historic American Engineering Record (HAER) are records of America’s built environment in multi-format surveys including measured drawings, large-format photographs, and written histories.

An excellent planning tool for successfully managing and maintaining a historic property is to develop a Preservation Management Plan. The Historic Building Preservation Plan (HBPP) works as a guide for what areas within your historic property need to be maintained.

There are many resources available for historic property Owners, above tax incentives. Grants can aid in updating the property for accessibility, or updated programs to be included in a historic property.

A feasibility study is a compilation of an existing facilities survey and conditions assessment, as well as a Preservation Plan document for a historic property. Included in the study is a building history report, review of the existing conditions.
