The Secretary of the Interior’s Standards for Rehabilitation

The U.S. Secretary of the Interior is responsible for establishing standards for all national preservation programs under Departmental authority and for advising federal agencies on the preservation of historic properties listed in or eligible for listing in the National Register of Historic Places.

The U.S. Department of the Interior Standards for Rehabilitation address the most prevalent historic preservation treatment today: rehabilitation. Rehabilitation is defined as the process of returning a property to a state of utility, through repair or alteration, which makes possible an efficient contemporary use while preserving those portions and features of the property which are significant to its historic, architectural, and cultural values.

The Standards that follow were originally published in 1977 and revised in 1990 as part of Department of the Interior regulations (36 CFR Part 67, Historic Preservation Certifications). They pertain to types, sizes, and occupancy and encompass the exterior and the interior of historic buildings. The Standards also encompass related landscape features and the building’s site and environment as well as attached, adjacent or related new construction.

The Standards are to be applied to specific rehabilitation projects in a reasonable manner, taking into consideration economic and technical feasibility.

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 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 altercations, 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.

Historic Preservation Standard Definitions

Based on the Secretary of the Interior’s Standards for the Treatment of Historic Properties these guidelines can help you maintain the historical integrity of your property. The way in which we treat historic properties today can have a great impact on how future generations interpret the work of our restoration efforts.

Treatment Options

Preservation treatment places a high premium on the retention of all historic fabric through conservation, maintenance and repair. It reflects a buildings continuum over time through successive occupancies, and the respective changes and alterations that are made.

  • Use the property as it was used historically or find a new use that maximizes retention of distinctive features.
  • Preserve the historic character (continuum of property’s history).
  • Stabilize, consolidate, and conserve existing historic materials.

Rehabilitation emphasizes the retention and repair of historic materials, but more latitude is provided for replacement because it is assumed the property is more deteriorated prior to work.

  • Use the property as it was used historically or find a new use that requires minimal change to distinctive features.
  • Preserve the historic character.
  • Repair deteriorated historic materials and features. Replace a severely deteriorated feature, using to the greatest extent possible, matching new materials.
  • New additions and alterations should not destroy historic materials or character. New work should be differentiated from the old, yet compatible with it.

Restoration focuses on the retention of materials from the most significant time in a property’s history, while permitting the removal of materials from other periods.

  • Use the property as it was historically or find a new use that reflects the property’s restoration period.
  • Remove features from other periods, but document them first.
    Stabilize, consolidate, and conserve features from the restoration period.
  • Replace a severely deteriorated feature from the restoration period with a matching feature.
  • Replace missing features from the restoration period based on documentation and physical evidence. Do not make changes that mix periods and falsify history to create a hybrid building.
  • Do not execute a design that was never built

Reconstruction establishes limited opportunities to re-create a non-surviving site, landscape, building, structure or object in all new materials.

  • Do not reconstruct vanished portions of a property unless the reconstruction is essential to the public understanding.
  • Reconstruct to one period of significance based on documentary and physical evidence.
  • Precede reconstruction with thorough archeological investigation.
  • Preserve any remaining historic features.
  • Recreate the appearance of the property (substitute materials may be used).
  • Identify the reconstructed property as a contemporary re-creation.
  • Do not execute a design that was never built.

What makes a home historic?
Does your house have significant character, interest or value as a part of the heritage of the county, state or nation? Did an historic event take place on the property? Does it represent the work of a master craftsman, architect or builder? Is it a rare example of a particular period, style material or construction technique? Does it reflect the cultural, economic, social; or political history of Frederick County? Does it possess significant artistic value? Can your house be identified with a person or group who influenced society?
