Design Guidelines
I.
Introduction
With the goal of preserving the unique historical and environmental qualities of a residential neighborhood in the City of Jefferson, under provisions of Sec. 8-43-D,
the Jefferson City Code, a majority of the homeowners in the neighborhood hereby petition the City to create the Lower Jefferson Conservation District, a
Neighborhood Conservation Planned District.
These design guidelines establish certain standards that will protect the character of the district and encourage appropriate development in the district.
II. Goals and Objectives
The goals and objectives of the Conservation District and these guidelines are:





To assist homeowners and other parties with restoration, alteration or additions to
buildings, so that the character defining qualities of the district are preserved and
maintained.
To increase awareness of the unique aesthetic, architectural and historic qualities of the
district and to promote education and neighborhood involvement toward this goal.
To eliminate unnecessary demolition, destruction, and neglect of this important part of
Jefferson City’s history.
To stimulate the economic health of the area and enhance residential property values
within the district.

III. Description
The Lower Jefferson Conservation District is a collection of mostly intact late 19th and early 20th century single family
residences and duplexes located on West Main Street in Jefferson City. The district is bounded on the north by the Union
Pacific tracks, on the east by Brooks Street, on the west by the junction of West Main and High Streets and includes those
properties facing or with side elevations along West Main Street. A listing of properties included in the district is included in
Appendix A.
Clearly visible from the Missouri River Bridge, the Lower Jefferson District sits on the southern bluff overlooking the
Missouri River and is located approximately 1 mile from the center of Jefferson City. The eastern end of the district is defined
by the historic waterworks complex and its tower which has overlooked the district since the majority of the buildings in the
district were erected.
The northern portion of the district consists of large lots containing: a nursing home complex—the Heisinger Lutheran Home
(including the Sam A. Cook and the Thomas Price Home), St. Peter’s Cemetery and the Taylor Home. These properties
contain a large number of mature trees and some buildings on these lots are set back 150 to 180 feet from West Main Street.
This deep setback provides an unique openness that is a key character defining feature of the district. This area is richly
blessed with mature trees and landscape features. The area offers one of Jefferson City’s most majestic views of the Missouri
River below. The larger tracts on the north side of West Main Street offer an important balance to the denser historic
development to the south. The residences on the north side of West Main Street are grander in scale than their neighbors to the
south. The three buildings on the northern side of West Main represent some of the best examples of early 20th century
residential architecture in the City.
The buildings located on the south side of West Main Street are typically smaller and more vernacular in terms of architectural
style. They are characteristic of working class homes that were built in the late 19th and early 20th centuries. These houses are
sited on a more typical urban plat with lots being relatively narrow and deep. Access to parking and garages is supplied by
an alleyway that runs parallel to West Main Street. Front setbacks are typically less than 20% of the overall depth of the
Fig. 2 The historic water tower on the
eastern end of the district has
individual lots. Side setbacks are also modest. This creates a rhythm between properties that is a characteristic element of

the district.
for over one hundred years.
Houses in the district are one-story, one-and-a-half-story, two stories or two and one-half stories in height with the floor to
ceiling height of each story between 9 and 11 feet. The vast majority of houses in the district have some form of front porch. Turned porch columns and balustrades
are found on many of these buildings. Many of the buildings sit on raised foundations of native stone. A number of the homes feature late-Victorian or early 20th
century architectural details such as fish scale shingles, carved wooden entry doors, turned balusters and columns, and leaded or stained glass windows, transoms or
sidelights.

Historically the old West School located at 1107 West Main Street was, for many years,
the center of neighborhood life and activity. Built in 1903, the building predates many of
the residences that surround it. The presence of a school building in the neighborhood
undoubtedly hastened the growth and development of the neighborhood. By the 1920’s
the majority of buildings in the neighborhood had been constructed. The historic West
School building has been adaptively reused as an apartment complex.
Today, West Main Street, although a busy thoroughfare, remains a popular route for
joggers, strollers, dog walkers and bicyclists.

side of West Main Street are important landscape features
that contribute to the character of the district.

IV. Architecture Styles and Features
The Lower Jefferson Conservation District contains a variety of architectural examples with the majority of the buildings dating from the 1880-1930 period. (The
District contains one earlier Greek Revival House at 1201 West Main which likely predates the main period of significance.) Most of the buildings are of modest
scale, typically one to two stories in height. Houses are rarely wider than 25 to 30 feet. Full width front porches are a common feature and are found on most
of the buildings in the District.
Typical building materials found in the district include: brick, frame, stucco and one unusual example of pressed concrete block. Characteristic roof forms include,
gable, hipped and gambrel.
Four types of late 19th and early 20th century architectural styles predominate in the District. These include American Folk Victorian, Bungalow, American
Foursquare and Picturesque Revival styles.
Fig. 5 A number of homes in the district are mail-order, pre-cut kit
homes. The kit for the bungalow at 200 Hart Street could have
been purchased for $861 in 1961.

A.
American Folk Victorian
American Folk Victorian homes date from the 1880’s to 1910’s. These modest homes were
typically vernacular in form but often contained details and features characteristic of high
style buildings, such as the Queen Anne, Gothic Revival, Italianate and Stick. These
buildings are sometimes called Carpenter Builder or Worker’s Cottages. With the advent of
the railroads, building materials and architectural ornamentation could be shipped vast
distances and became readily available.
In the District, both one and two story examples can be found. The most common form is
the gable front and wing. Porches, frequently with turned wooden columns, are typically
located in the corner between the front gable and the side wing. In some examples, added
ornamentation, such as decorative shingles, can be found in the gable end. Both brick and
frame examples are found in the District.

B.
Bungalow
Following the tradition of the Arts and Crafts movement which stressed utility and
simplicity, the Bungalow became a symbol of the movement with its low, overhanging
roof, broad porches, and simple horizontal lines. Identified as the most common example
of Craftsman architecture, the Bungalow, which originated in California, spread quickly
across the country during the early 20th century. Many architectural plan books featuring
bungalow and pre-cut bungalow homes were shipped throughout the country. A wide
diversity of bungalow examples can be found in the historic neighborhoods of Jefferson
City.
The typical Bungalow is a one or one-and-one-half story, wood or masonry structure with
a gently pitched, front or side gable roof. An additional gable occasionally covers an open
porch and the overhang is usually supported by battered or “elephantine” porch piers or
thick columns. Some Bungalows have clipped gables, shed dormers, knee braces or
exposed rafter ends, but almost all have a front porch. Use of native stone for porch bases
and chimneys is common.
Fig. 9 The gable dormer, wide eaves, exposed rafter ends, knee
braces and full width porch are characteristics of bungalows.
The red tile roof is a fine feature of this early 20 th century home.

C.
American Foursquare
One of the most commonly found styles in Jefferson City residential buildings after 1900;
the American Foursquare is easily recognized by its square plan and overall simplicity. The
majority of these houses were built during the first three decades of the 20th century. These
homes were also popularized in architectural plan books and were frequently available as
pre-cut kit homes. The typical Foursquare is a two-story hipped roof structure with central
dormer, minimal decoration, broad overhanging eaves with brackets or modillions and a full
width front porch.
American Foursquare homes often enhanced with Craftsman, Prairie, Colonial Revival,
Neo-classical or other formal stylistic details. Some Foursquares feature hipped gables on
each plane of the roof. Occasionally, a Foursquare will feature a front gable roof or will be
considerably larger with more elaborate ornamentation. But, in each case, the basic square
plan is the predominant defining feature.

D.
Picturesque Revival Styles
The early part of the 20th century saw the blossoming of a variety of styles that featured revivals of earlier architectural styles. As Architecture became an
established profession, a rediscovery of academic interest in earlier architectural styles took place. Picturesque Revival styles drew their inspiration from these
earlier styles. Among the styles that achieved popularity during this period were the Colonial Revival, the Tudor or English Revival, the Italian Renaissance
Revival and the Dutch Colonial Revival. Examples of each of these revival styles can be found in the district.
1.
Colonial Revival
Beginning with the Philadelphia Centennial Exposition of 1876, Americans began to
experience a renewed interest in their Colonial heritage. The first attempts at Colonial
Revival architecture merely adapted decorative element and design characteristics from
Colonial structures to fit the size and scale of the still popular Victorian era. It was not until
the first decade of the 20th century, with the widespread distribution of photographs, pattern
books and periodicals that the revival began to encourage historically accurate copies using
correct proportions and details of colonial architecture.

2.
Dutch Colonial Revival
The gambrel roof is the distinguishing feature of the Dutch Colonial Revival. Primarily a
residential style, it was popular between 1900 and 1925. Other characteristic elements
included wide overhangs, dormers, small oval windows in the gable ends, and a porch under
the overhanging eaves of the gambrel roof, supported by columns. The gable ends typically
face sideways. Occasionally there is a gambrel roofed rear wing which intersects with the
front gambrel roofed block.

characteristic gambrel roof. The full width porch with
turned columns and balustrade, and entry with leaded glass
transforms and side lights make this an excellent example
of the style. The first floor is constructed with unusual
rock-faced concrete block.
Tudor or English Revival
The Tudor or English Revival style includes a variety of English medieval or renaissance styles
including the Norman, Tudor, Jacobean/Elizabethan styles of residential architecture. Buildings
are typically one story to 1 ½ story structures generally composed of brick, stucco or occasionally
stone. The most distinguishing feature is the steeply pitched roof and steeply pitched projecting front
entrance. Many cottages have arched or straight-headed picture windows on the front facade, but other
fenestration is limited. Windows are occasionally casements divided by heavy metal mullions. Decorative
brickwork, half-timbering, arched entrances, and small-paned windows are also characteristic. A variation
of the style, the Neo-Jacobean Revival, was frequently used for academic architecture. The Old West
School at 1107 West Main was constructed in this style.

4.
Renaissance Revival
Renaissance Revival is best identified by the horizontal divisions, usually defined by belt or string courses, and the different treatment in each division. This is
sometimes accomplished by using different materials for each floor or section and by changing window surrounds, shapes, or sizes. Arcades and arched openings,
quoins, projecting cornices with modillions and dentils, and engaged columns and piers are also characteristic of this style. The vernacular examples are generally
less ornate and on a smaller scale. They do, however, employ some of the same details, particularly arcades, quoins, and enriched cornices. Italian Renaissance and
what may be considered Beaux Arts are also included in the Renaissance Revival.

most recent resident was Missouri’s current governor, Bob
Holden.

V. Guidelines for Rehabilitation of Existing Buildings
The guidelines shall apply to exterior rehabilitation work only.
A.
General Objectives
1.
Rehabilitation work should maintain and be consistent with the historic architectural styles, date/period and detailing of the structure.
2.
Rehabilitation work which is intended to enhance or return the structure to its original historic appearance should be based upon
historic, physical, or pictorial evidence, rather than on conjectural designs. Work that has no historical basis and which seeks to
create a different appearance is discouraged.
3.
Work should first attempt to repair and maintain the existing elements of the structure, whenever reasonably possible.
In the event replacement of details and materials is necessary, when possible, these elements should match the elements
being replaced in size, shape, materials, pattern, texture and directional orientation of installation.
B.
Building Wall Material Requirements
1.
Existing wall materials and details shall be retained through repair and maintenance, unless deteriorated beyond
reasonable repair.
2.
When replacement of existing materials and details is required, the new materials shall be similar in appearance,
maintaining the original materials in size, shape, pattern, texture and directional orientation of installation.
3.
Masonry walls shall maintain their present or original appearance. Paint may be removed from masonry surfaces to return
to the original appearance. The painting of, or the removal of paint, from a masonry surface shall be done only if necessary
to preserve deteriorating masonry surfaces and the historic integrity of the structure. To prevent damage, masonry shall be
cleaned by the gentlest means possible. Abrasive cleaning methods, such as sandblasting, shall be avoided.
4.
The use of steel, aluminum, or vinyl siding as a replacement material is discouraged, but may be acceptable if these materials
maintain the character of the structure and the original siding shape, pattern, texture and directional orientation. Character
defining details and elements such as, but not limited to, window/door trim and detailing, eave brackets, porch columns and railings, and
other special elements and details which give the structure its character and appearance, shall be retained when applying steel, aluminum, or vinyl siding.

Requirements for Windows and Doors
1.
Existing windows and doors, their glazing, trim, and the character defining elements shall be retained through repair
when reasonably possible.
2.
Existing window and door locations shall be retained, not removed, covered or filled in.
3.
Replacement windows and doors shall be similar in sash design and appearance, maintaining the original size, shape,
muntin pattern, glazing area and tint, and placement location.
4.
Replacement windows having thermal and maintenance reducing qualities may be used, but shall maintain those
appearance and character defining elements described above.
Fig. 18 Architectural details
such as windows, dormers and
doors are character defining
features of the district. They
add visual richness and should
be preserved.
5.
New window and door openings shall maintain the building’s facade proportions and rhythms, and shall match the
existing window and door design. Where the building code requires egress, larger windows may replace original small
windows so long as they are compatible in style with the original windows. Every effort, however, shall be made to
place replacement egress windows on secondary or rear elevations.
6.
Replacement trim materials shall be similar in appearance, maintaining the original materials’ size, shape, pattern, texture and
detailing.
7.
Window features and accessories, such as storm windows, screens, awnings, and shutters shall maintain the appearance of the
main window and the building’s facade proportions and rhythms.
8.
Door features and accessories, such as storm doors, screens, sidelights, and transoms shall maintain the appearance of the main
door and the building’s facade proportions and rhythms.
D.
Requirements for Roofs
1.
Roof forms and architectural features such as, but not limited to, dormers, chimneys, overhangs, eaves, eave brackets or lookouts, and fascia, which give the
roof its essential character shall be retained through repair when reasonably possible.
2.

VI. Guidelines for Additions to Existing Structures
A.
General Objectives
1.
5.
Additions should be located on side or rear facades where the character defining elements and visual appearance of the front facade of the structure will not
be obscured, damaged or destroyed, when reasonably possible.
Additions to existing structures that are visible from the street should maintain and not detract from the appearance and character defining elements of the
existing structure, their scale and proportions.
Additions should provide consistency and continuity through the use of similar forms, massing, rhythms, details, height, directional orientation of building,
element lines and materials.
Vertical additions should maintain the established height of the structures along the same street. These additions shall maintain the established rhythms and
proportions that are established by the lower portions of the structure and shall maintain the structure’s architectural integrity.
If possible, design additions so that they can be removed in the future without damaging the existing building.
B.
Building Site Requirements
1.
Additions shall maintain the building setbacks from the street and for the side yards as defined by the other buildings along the same streets. When the
setback pattern varies, the addition shall be maintained between the minimum and maximum setbacks that are defined by the other buildings along the same
side of the street, established as follows: (a) Front yard setbacks shall be established by averaging the existing front yards along the street frontage in the
same block and on the same side of the street; (b) Side and rear yard setbacks shall be as required by the Zoning Code.
Subject to the provisions of Paragraph 3 below, paving within the front yard shall be limited to primary driveways and sidewalks. The surface area of
driveways and sidewalks shall not exceed 30% of the front yard lot area. Parking areas shall be located behind the front plane of the building in the side or
rear yard or inner courtyards, except as provided for allowable parking lots as described in this section.
Allowable parking lots for land uses requiring ten (10) or more spaces may be located in the front yard provided the parking lot is a minimum of 30 feet
from the front property/right-of-way line. Parking lots shall be screened from view along the front and side property lines with a perimeter strip containing a
combination of medium-to-large canopy (deciduous) trees and evergreen trees, planted three (3) trees per 100 linear feet; plus a barrier feature such as a
hedge, berm, fence, wall or combination of such features, with minimum height of three (3) feet. Up to ten percent (10%) of the length of a screen may be
interrupted for access to the property; however, at least one driveway access shall be permitted for each development. All plants shall be selected from the
Approved Planting List, on file in the Department of Planning and Code Enforcement. Parking lot design and landscaping shall comply with the provisions
of the Zoning Code.

Addition of landscaping features such as, but not limited to, walls, fencing, lighting and planters shall be consistent with the appearance and general
character of those same elements that exist along the same street and neighborhood.
C.
Requirements for Building Materials and Elements
1.
Building materials shall create a visual consistency and continuity between the existing structure and the addition. This may be achieved, first, through the
continued use of materials that are present on the existing structure or, secondly, through the use of different materials that maintain the same scale,
proportions, rhythms, and directional orientation as those present on the existing structure.
Building elements, their location, and the sight lines that they establish shall be continued to the addition to create a visual consistency and continuity. This
may be achieved through maintaining such elements, details and building lines as the established height of windows and doors, the repetition of window
glazing patterns, the continuance of the roof forms, eave lines and overhangs, the continuance of special detailing present on the existing structure.
Design the foundation height and the eave lines of additions generally to align with those of the existing building. Interior floor-to-ceiling heights on the
front elevation shall not be less than nine (9) feet, with a maximum story height of 12 feet. Additions to front facades shall have the appearance of having
no more than two and one-half (2-1/2) stories and be limited to 35 feet in height. Where front setbacks greater than 35 feet are possible, the Differential
height/Setbacks Schedule in Section VII, Paragraph D.1. © may be used to establish setback and building height.
For the purposes of this section, “building height” shall be the vertical distance from the grade within 10 feet of a building to the (a) highest point of a flat
roof; (b) the dock line of a mansard roof; or (c) the average height between eaves and ridge for gable, hip, and gambrel roofs, as averaged from around the
building.

D.
Requirements for Roofs
1.
2.
New roof features, such as dormers, may be added to the existing roof, if such elements maintain the structure’s established rhythms, scale, proportions, and
architectural appearance and character.
Roof forms on additions shall maintain the existing structure’s appearance and character through similar roof forms, slope and detailing.
E.
Requirements for Porches
1.
2.
Enclosure of porches and entries shall maintain the structure’s existing rhythms, scale, proportions, appearance and character.
When required to achieve access to the first floor level, handicapped ramps may be installed and shall be constructed so that in the future, the ramp may be
removed without significantly altering the original structure.

VII. Guidelines for New Construction
A.
General Objectives
1.
Designs for new construction need not duplicate existing styles within a
district, but should draw upon common characteristics of structures in the
approximate neighborhood to provide a continuity and consistency.
Characteristics, such as, but not limited to, porches, entries, roof slope and
form, and window/door styles, maintain the continuity and consistency of
new construction within the district.
New construction should respect the established area’s scale, proportions,
2.
rhythms, and relationships of both principal and accessory structures.
Fig. 22 New construction should appear similar in scale to
that of single-family structures seen traditionally in the
neighborhood, such as the example on the right.
B.
Building Site Requirements
1.
Keep the orientation of the proposed building’s front elevation to the street consistent with the orientation of existing buildings’ front
elevation to the street.
New secondary structures, such as detached garages, shall maintain their secondary relationship with the primary structure.
Subject to the provisions of Paragraph 4 below, paving within the front yard shall be limited to primary driveways and sidewalks. The
surface area of driveways and sidewalks shall not exceed 30% of the front yard lot area. Locate new parking areas as unobtrusively as
possible behind the front plane of the building in the side or rear yard or inner courtyards, except as provided for allowable parking lots as
described in this section.
Allowable parking lots for land uses requiring ten (10) or more spaces may be located in the front yard provided the parking lot is a
minimum of 30 feet from the front property/right-of-way line and is screened from view along the front and side property lines with a
perimeter strip containing a combination of medium-to-large canopy (deciduous) trees and evergreen trees, planted three (3) trees per 100
linear feet; plus a barrier feature such as a hedge, berm, fence, wall or combination of such features, with minimum height of three (3) feet.
Up to ten percent (10%) of the length of a screen may be interrupted for access to the property; however, at least one driveway access shall be
permitted for each development. All plants shall be selected from the Approved Planting List, on file in the Department of Planning and
Code Enforcement. Parking lot design and landscaping shall comply with the provisions of the Zoning Code.
Use driveways and alleys to access side and rear parking areas and garages. Attached garages shall not be located on the front facade of a
new building unless incorporated into the mass of the building, with the garage doors oriented to the side or rear. “Snout houses” where a
garage projects from the front facade shall not be permitted.

For new parking areas, use paving material that is compatible with traditional paving materials for driveways in the district. Parking areas
and driveways shall be designed in accordance with standards of the Department of Public Works. Acceptable paving materials include
pavers, concrete, textured concrete, aggregate, asphalt, and other paving material approved by the Department of Public Works. Gravel
shall not be utilized.
Existing large trees and other significant landscape features shall be incorporated into plans for additions and new construction. Where
existing trees and other significant landscape features cannot be retained, new trees and landscape features shall be incorporated into the
plans and installed on the site. Outside of parking lot landscape areas, trees used to replace existing trees which must be removed shall have
a minimum diameter/caliper of one and one-half inches (1-1/2”) measured six inches (6”) above the ground.
Existing historic site features such as retaining walls, gate posts and tree guards shall be retained, replaced in kind, or similar features
incorporated in the design.
New landscaping features such as, but not limited to, walls, fencing, lighting, and planters, shall be consistent with the general character of
those same elements that exist along the same street and approximate neighborhood.
Fig. 23 As seen from St. Peter’s Cemetery the Lower
Jefferson Conservation District contains one of the best overlooks
of the Missouri River in Jefferson City. Landscape features that
contribute to the character of the district shall be preserved.

1.
Materials and elements shall maintain the visual characteristics, scale, proportions, directional orientation and rhythms that are created by the materials on
existing structures, and shall maintain the district’s overall appearance and character.
D.
Building Requirements
1.
Design the height of the proposed building to be compatible with the height of existing buildings in the Lower Jefferson Conservation District. Except as
provided below in the Differential Height/Setback Schedule, minimum setbacks for new construction shall be established by averaging the existing front
yards along the street frontage in the same block and on the same side of the street; (b) Side and rear yards shall be as required by the Zoning Code.
(a)
Interior floor-to-ceiling heights on the front elevation shall not be less than nine (9) feet, with a maximum story height of 12 feet.
(b)
Except as provided in the Differential Height/ Setback Schedule, new buildings constructed shall have the appearance from the front street line, of
having no more than two and one-half (2-1/2) stories, and be limited to 35 feet in overall height.
(c)
Differential Height/Setback Schedule. For every five feet of setback greater than 35 feet, an additional one (1) foot in height shall be permitted up
to a maximum setback of 85 feet and maximum height of 45 feet and three (3) stories; according to the following schedule:
Setback 40 feet Building height =36 feet Stories= 2-1/2

with existing roofs in the district.
Utilize new windows and doors that are compatible in proportion, shape, position, location, pattern, and size
with windows and doors of existing structures in the district. On the facades visible from the front street line, individual window units shall not exceed 48
inches. Compatible groupings of double hung windows are acceptable. The separation between individual windows in these groupings shall not be less than
four (4) inches. Use of more than three (3) single window units in a grouping is not appropriate. New windows shall follow the traditional proportion of
being taller than they are wide.

4.
Keep the roof shape of the proposed building consistent with roof shapes in the district: gable, hip and gambrel. Roof pitch shall be consistent with other
existing structures in the district.
5.
Keep the predominant material of the proposed building consistent with historic materials in the district: brick, stone, stucco, and wooden clapboard siding.
Use of synthetic materials is discouraged; however synthetic materials may be substituted for historic materials if approved on a case by case basis. Synthetic
materials shall be specifically identified and approved on an individual basis by
the Department of Planning and Code Enforcement.
6.
Make the scale (the relationship of a building’s mass and details to the human
figure) of the proposed building compatible with the scale of existing structures
in the district.
7.
Ensure that the architectural details of the proposed building complement the
architectural details of existing structures in the district.
8.
Contemporary construction that does not directly copy from historic buildings in
the district but is compatible with them in height, proportion, roof shape,
material, texture, scale, detail, and color, is strongly encouraged.
9.
New single family structures shall maintain the traditional neighborhood scale.
10.
New non-single family structures shall (a) include architectural details on
the building facades visible from the street which compliment the existing
residential architecture in the district; and (b) shall be divided into smaller
modules that are similar in size and scale to traditional single family
houses in the district.
11.
New non-single family structures with front building facades of 100 feet or more in width which are parallel with West Main Street or within 30 degrees of
being parallel with this street shall incorporate the following design detail into the front building facades: (a) each module width shall not exceed 20
percent (20%) of the width of the front facade, and (b) each module shall be off-set from the front facade a minimum of five percent (5%) of the total width
of the facade.
12.
For the purposes of this section, “building height” shall be the vertical distance from the grade within ten (10) feet of the building to the (a) highest point of
a flat roof; (b) the dock line of a mansard roof; or (c) the average height between eaves and ridge for gable, hip, and gambrel roofs, as averaged from around
the building.

Fig. 25 In this example of compatible new construction, the buildings
are broken-up into smaller modules to reflect traditional neighborhood
scale. Traditional building heights, roof shapes and forms are maintained.
Parking is located in a center parking court hidden from the street. The
units feature street-oriented entry porches. This type of new construction
maintains the character of the district.

Appendix B: Preservation Briefs
The National Park Service’s (NPS) Preservation Briefs assist owners and developers of historic buildings in recognizing and resolving common preservation and
repair problems prior to work. The briefs are especially useful to preservation tax incentive program applicants because they recommend those methods and
approaches for rehabilitating historic buildings that are consistent with their historic character. The complete text of briefs 1-41 is available. Preservation Briefs are
now available on-line and can be downloaded from the NPS web site. The address is:
