GUIDELINES FOR REHABILITATING HISTORIC BUILDINGS: ENTRANCES AND
U.S. Department of the Interior

Preservation Assistance Division
An illustrated booklet addressing the Secretary's Standards and the
guidelines is available from the U.S. Government Printing Office.
The title is "The Secretary of the Interior's Standards for
Rehabilitation & Illustrated Guidelines for Rehabilitating Historic
Buildings", ISBN 0-16-035979-1.
Each of the guidelines included in the booklet mentioned above have
been separated into individual entries for specific use in HBPP.
This entry represents one of many guidelines included in the
booklet and describes RECOMMENDED and NOT RECOMMENDED applications
of the Secretary of the Interior's Standards as they relate to
Entrances and Porches. For a list of the Secretary of the
Interior's Standards for Rehabilitation, see 01091-04-S; For
general information relating to the purpose, organization and
content of the individual guidelines, see 01091-05-S. Both of
these entries should be referenced along with the information
contained in this document.
ENTRANCES AND PORCHES:
Entrances and porches are quite often the focus of historic
buildings, particularly when they occur on primary elevations.
Together with their functional and decorative features such as
doors, steps, balustrades, pilasters, and entablatures, they can be
extremely important in defining the overall historic character of
a building. Their retention, protection, and repair should always
be carefully considered when planning rehabilitation work.
IDENTIFYING, RETAINING AND PRESERVING
- Identifying, retaining, and preserving entrances -- and
their functional and decorative features -- that are
important in defining the overall historic character of
the building such as doors, fanlights, sidelights,
pilasters, entablatures, columns, balustrades, and
- Removing or radically changing entrances and porches
which are important in defining the overall historic
character of the building so that, as a result, the
character is diminished.
- Stripping entrances and porches of historic material such
as wood, iron, cast iron, terra cotta, tile and brick.
- Removing an entrance or porch because the building has
been reoriented to accommodate a new use.
- Cutting new entrances on a primary elevation.
- Altering utilitarian or service entrances so they appear
to be formal entrances by adding panelled doors,
fanlights, and sidelights.
PROTECTING AND MAINTAINING
- Protecting and maintaining the masonry, wood, and
architectural metal that comprise entrances and porches
through appropriate surface treatments such as cleaning,
rust removal, limited paint removal, and re-application
of protective coating systems.
- Failing to provide adequate protection to materials on a
cyclical basis so that deterioration of entrances and
- Evaluating the overall condition of materials to
determine whether more than protection and maintenance
are required, that is, if repairs to entrance and porch
features will be necessary.
- Failing to undertake adequate measures to assure the
preservation of historic entrances and porches.
- Repairing entrances and porches by reinforcing the
historic materials. Repair will also generally include
the limited replacement in kind -- or with compatible
substitute material -- of those extensively deteriorated
or missing parts of repeated features where there are
surviving prototypes such as balustrades, cornices,
entablatures, columns, sidelights, and stairs.
- Replacing an entire entrance or porch when the repair of
materials and limited replacement of parts are
- Using a substitute material for the replacement parts
that does not convey the visual appearance of the
surviving parts of the entrance and porch or that is
physically or chemically incompatible.
- Replacing in kind an entire entrance or porch that is too
deteriorated to repair -- if the form and detailing are
still evident -- using the physical evidence to guide the
new work. If using the same kind of material is not
technically or economically feasible, then a compatible
substitute material may be considered.
2. Not Recommended:
- Removing an entrance or porch that is unrepairable and
not replacing it; or replacing it with a new entrance or
porch that does not convey the same visual appearance.
NOTE: THE FOLLOWING REPRESENTS PARTICULARLY COMPLEX TECHNICAL OR
DESIGN ASPECTS OF REHABILITATION PROJECTS AND SHOULD ONLY BE
CONSIDERED AFTER THE PRESERVATION CONCERNS LISTED ABOVE HAVE BEEN
DESIGN FOR MISSING HISTORIC FEATURES
- Designing and constructing a new entrance or porch if the
historic entrance or porch is completely missing. It may
be a restoration based on historical, pictorial, and
physical documentation; or be a new design that is
compatible with the historic character of the building.
- Creating a false historical appearance because the
replaced entrance or porch is based on insufficient
historical, pictorial, and physical documentation.
- Introducing a new entrance or porch that is incompatible
in size, scale, material, and color.
ALTERATIONS/ADDITIONS FOR THE NEW USE
- Designing enclosures for historic porches when required
by the new use in a manner that preserves the historic
character of the building. This can include using large
sheets of glass and recessing the enclosure wall behind
existing scrollwork, posts, and balustrades.
- Enclosing porches in a manner that results in a
diminution or loss of historic character such as using
solid materials such as wood, stucco, or masonry.
- Designing and installing additional entrances or porches
when required for the new use in a manner that preserves
the historic character of the building, i.e., limiting
such alterations to non-character-defining elevations.
- Installing secondary service entrances and porches that
are incompatible in size and scale with the historic
building or obscure, damage, or destroy character-defining features.
