Staff Report May 5, 2022
Historic Review for HPC22-0016: 521 South Governor Street
District: Governor-Lucas Street Conservation District
Classification: Non-contributing
The applicant, Donna Brooks, is requesting approval for a proposed demolition and new construction project
at 521 South Governor Street, a Non-contributing property in the Governor-Lucas Street Conservation
District. The project consists of the demolition of the existing two-car garage and the construction of a new
two-car garage.

Staff Comments
This two-story house was built ca 1910-1915 as a side-gabled house with a two-story shallow front projection.
In the 1926 Sanborn Fire Insurance map the property had a rear one-story portion behind the south half of
the house. This portion was removed by the late 1950s. In 1940, the garage was added. In 1968 the aluminum
siding was added. The current flat front with overly large front-facing gable is an alteration but the original
configuration is unknown. In the current configuration, the house appears to be a Colonial Revival house. In
late 2007 the Commission approved the construction of a one-story rear addition in the area where the one-
story portion had been removed.
The applicant is proposing to demolish the existing, deteriorated two-car garage and construct a new garage.
The proposed new garage would be a 22 foot by 26 foot two-car garage with a two-car overhead door on the
west side and a 24” x 30” window and a passage door on the east side. The proposed window is a vinyl
window with brickmold and with a fixed sash above and an inward opening hopper sash below. The siding
would be vinyl lap siding with vinyl corners and metal soffits. A vinyl shingle siding would be added to the
gable of the east (house-facing) side. New drawings, showing appropriate trim have been submitted. The
proposed trim material would be LP Smartside. The proposed passage door would be a pressed steel door
with brickmold. The roof will be architectural asphalt shingles. The roof will have a minimal overhang
matching the house.
Section 7.1 Demolition guidelines recommend retaining historic garages. If the period garage is insufficient
for modern-day vehicles, efforts should be made to construct a new garage on another portion of the site.
New garages should be designed to be compatible in design with the primary structure and/or outbuildings in
the neighborhood.
Section 6.2 New Outbuildings recommends placing new outbuildings to the rear of the primary building and
constructing garages that are clearly subordinate in size and ornamentation to the primary structure but reflect
the style of the primary structure. It is recommended to install single-car garage doors; double-car garage
doors are discouraged. It is also recommended to add trim around garage door openings that matches the
trim of other doors and windows on the building. It is recommended to incorporate windows into the design
that are relatively small and rectangular. The simple garage design drawings in this section include corner
boards, a frieze board, and door and window trim, which are all elements of trim that are part of the
architectural language on any new outbuilding in a historic or conservation district.
Section 6.2 New Outbuildings includes two documented exceptions for properties in Conservation Districts
that the Commission may consider for this property. The first exception allows the Commission to consider
the use of synthetic siding on new outbuildings. The second allows for the Commission to consider the use of
vinyl or vinyl-clad windows on new outbuildings.
Section 4.3 Doors includes several guidelines already mentioned in 6.2 including using overhead doors that
resemble historic ones or are simple, adding trim around these doors, and using two single-car doors instead
of one two-car door. For passage doors, it is recommended to substitute a material in place of wood only if
the material retains the style and appearance of the historic doors and must be durable, accept paint, and be
approved by the Commission. The Commission has approved fiberglass doors in place of wood, but not steel
doors. This section also includes an exception for properties in Conservation Districts. This exception allows
the Commission, on a case-by-case basis, to approve a double garage door for garages not highly visible from
the street.
Section 4.11 Siding provides more information about the use of synthetic siding. The documented exception
to allow synthetic siding includes some conditions including “the synthetic siding does not have a simulated
wood grain.”
Section 4.13 Windows states that windows on outbuildings should be relatively small and rectangular. This
section also has a documented exception for noncontributing and non-historic properties that says that for
outbuilding windows, vinyl or vinyl-clad wood windows may be considered, provided they match appropriate
historic outbuilding window proportions.
Section 4.14 Wood recommends substituting a material in place of wood only if the substitute material retains
the appearance and function of the original wood. The substitute material must be durable, accept paint, and
be approved by the Commission. For many applications, fiber cement board is an approved substitute for
wood provided the fiber cement board is smooth faced with no simulated wood grain. MiraTech and Trex are
two materials that can be approved on a case-by-case basis. It is disallowed to substitute a material in place of
wood that does not retain the appearance, function, and paintability of wood.
In Staff’s opinion, while the garage is old enough to be considered historic, it is also deteriorated. The
deterioration was documented and photographed when the applicant first purchased the house in 2018. New
photos by the applicant show that it has further deteriorated. Staff finds that the garage could be approved to
be demolished if the Commission can approve the new garage design.
Staff recommends any new garage in any district includes the minimum trim recommended, which would be
a standard flat casing on all windows and doors, corner boards, and a frieze board at the top of the wall under
the eave overhang and along the rake at the gable ends. For this reason, staff does not recommend any doors
or windows with brick mold (unless the building is masonry construction) or with J-channels for vinyl siding.
Flat casing would match the trim on the house. Brickmold would match the trim, or at least appear similar to
the trim on a masonry building.
The applicant for this project is seeking several exceptions, the use of vinyl windows, vinyl siding, and the use
of a two-car overhead door. Because this house is a noncontributing property in a Conservation District, staff
recommends the Commission consider approval of the use of vinyl or vinyl clad windows on this new garage.
Because the overhead doors will face the rear alley and will be hidden from view, staff recommends that the
Commission consider the approval of a two-car door.
Staff also recommends an exception to approve vinyl siding on the new garage. Our guidelines include
conditions for synthetic siding including the requirement that the material does not have a simulated wood
grain. In 2007, prior to the existences of the current iteration of our guidelines, the Commission approved a
rear addition on this house with vinyl siding that has a texture. Staff recommends approval of a vinyl siding
that matches the vinyl on the addition.
Staff recommends that the approved window is a double-hung, single-hung or fixed sash (with four simulated
divided lights). While the submitted window is a modern type of window, fixed sash with awning below, it
appears similar to a double or single hung. If it did not have brickmold and/or a J-channel for the connection
to vinyl siding without trim, staff would recommend approval. Instead, staff recommends approval of a vinyl
window with no brickmold. Staff also recommends allowing the applicant to omit the north-facing window
from the garage if they wish. Staff recommends that the approved passage door is a fiberglass door instead of
a steel door, does not have integral trim (brick mold), and has a half-lite with two panels below. A door with
no window could be approved if the door met the other conditions of material and no brickmold. Staff also
recommends that the overhead door is a simple smooth door instead of a modern pressed panel door.
The applicant’s contractor originally submitted the application without trim because the assumption was to
use vinyl corners and the trim that came integral to the submitted doors and window. As stated above, staff
recommends a simple, traditional trim to match the house. Vinyl siding can be installed to butt up against
window, door, and corner board trim. Vinyl corners are not required for vinyl siding installation. The LP
Smartside proposed for the other trim could be used for corner boards, too Staff recommends that the
Commission approve the project with corner boards instead of vinyl corners.
Recommended Motion
Move to approve a Certificate of Appropriateness for the project at 521 South Governor Street as presented
in the staff report through the use of exceptions for the use of smooth synthetic siding, vinyl windows and a
two-car overhead door, with the following conditions:
The overhead door is a smooth steel door without pressed panels
The windows are a historic style and do not have brickmold
The passage door is wood or fiberglass door that does not have brickmold

Architectural Description
This house, built ca. 1890, is a T-shaped vernacular cottage consisting of a two-story front facing gable and a
1 1/2-story side gable. Originally open porches were located in both of the Ell's on each side of the lower
portion. In ca. 1910, the rear open porch was modified to create a one-story kitchen addition. A rear-facing
dormer was also added to the back of this wing. The property also includes a barn-shaped house in the back
yard.
In 2021, the Commission approved the replacement of a south side window with a new window with a raised
sill and the installation of a full-light French Door on the rear of the one-story kitchen addition.
Project Description
The applicant is proposing to construct a two-story addition on the back of the north portion of the house.
This addition will be set in from the north edge of the house, retaining the original corner of the structure,
and will have a rear-facing gable, matching the existing condition. The addition will be slightly shorter than
the existing two-story gable to differentiate the addition from the original house. The first floor of the
addition will extend east into the rear yard further than the second floor, creating a second-floor deck. The
addition will have wood lap siding, trim and shingles to match the historic house. The eave overhang, soffits,
and any exposed foundation will also match the house. The railing on the second-floor deck will have newel
posts, a top and bottom rail suspended between posts and square spindles mounted between the rails instead
of attached to the outside of the rails, following the guidelines.
The current proposal has two options for the east, or rear-facing, window and door openings. Option A was
originally submitted with the application and includes four full-light glass doors on the east wall of the
addition, two per floor (see page 12 of the application materials included in the packet). Option B was
submitted in response to staff comments that Option A did not continue the window patterning on the
historic house. Option B (see page 19 of application materials) includes one window and one full-light door
on each level. Otherwise, Option A and B are the same. In both versions, the north wall of the addition
includes one window, continuing the window pattern on that side of the house.
The project also includes a deck constructed in the Ell created by the original kitchen addition and the new
two-story addition. The deck will not have a railing because it will be close to grade. The deck will be
constructed of wood and will extend to the south edge of this portion of the house, which does not extend to
the edge of the south-facing gable.
The final portion of the project includes repairs to the front porch and the relocation of the front door. As
shown in the photos on page 31 of the application materials, framing for a front door was found in the
proposed location for the door. This suggests that the front door was in this location at one time and was
relocated to the sidewall on the porch. The proposal is to return the door to this location, closing the wall
where it is currently located. The new door will be a half-light, fiberglass door. The existing door is a historic
door but is too narrow for the new location. The porch will be repaired as described in the application with a
new floor, stairs, and railing and a repaired porch roof.
Guidelines
The guidelines for new additions, Section 5.1, recommends that additions are designed so that they do not
diminish the character of the existing building by being placed at the rear of the property, distinguished from
the original by offsetting the walls or connecting with a breezeway, and using a palette of materials similar to
that on the house. Key horizontal lines such as eave height and window head height should be matched. It is
recommended to install doors in additions that match the material of historic doors and have a similar style
and appearance as the historic doors in the existing building. Windows be of a similar type, proportion and
divided light pattern as those in the original structure. Additions should be constructed with massing and
roofline consistent with the historic building so that wall areas and corners, roof pitches and spans all have a
proportion similar to the existing building. Roof overhangs and eaves should also match. Foundations should
appear similar to the historic foundation in color and texture.
Section 4.1 Balustrades and handrails recommends that new balustrades should have square spindles that are
1 ½ inches or greater in width. The top and foot rails should be at least two full inches thick. Top and foot
rails should be sloped on the top side to drain water. New balustrades and handrails should match the simple
balustrade drawing in the guidelines and be painted. Section 4.2 Doors recommends adding new door
openings that are trimmed to match other doors and windows in the building. It is disallowed to install flush
entrance doors or other modern door styles. Section 4.7 Mass and rooflines recommends preserving original
roof pitches and spans and preserving original wall and vertical corners that define the massing of a historic
building. Section 4.10 Porches recommends replacing badly deteriorated components with new ones that
match the historic components in design and material. It is also recommended to use vertical-grained Douglas
Fir porch flooring for its resistance to weathering and to use wood steps for a wood porch. Section 4.11
Windows recommends adding windows that match the type, size, sash width, trim, use of divided lights, and
overall appearance of the historic windows. It is also recommended to add new windows in a location that is
consistent with the window pattern of the historic building.
Section 5.2 Decks and Ramps recommends locating a new deck on the back of a primary building, opposite
the street-facing façade and set in from the side walls at least 8 inches. Decks should be designed so that the
size, scale and location do not detract from the character of the district’s rear yards. Decks should be attached
in a manner that will not damage a historic exterior wall.
Standard 6 of the Secretary of the Interior’s Standards discusses the replacement of deteriorated features and
then continues, replacement of missing feature shall be substantiated by documentary, physical, or pictorial
evidence.
Staff Recommendation
In Staff’s opinion, the project is described very well in the submitted application. The addition portion of the
project is designed in several ways to follow the guidelines: the project is on the back and set in from both
corners of the original two-story portion of the house. The roof slope, eave height and soffit detail are
repeated in the addition. The roof ridge is slightly lower than the main roof because of the setback with the
sidewalls, retaining the massing of the original building. The applicant plans to use wood siding and trim
matching the existing building.
The inclusion of a second-floor deck is often a more modern inclusion but there are examples of historic
houses with second floor decks over a single-story rear kitchen addition or a side sunroom. While new door
location is not directly discussed in the guidelines, window patterning is included. The originally submitted
Option A included four symmetrically located full-light doors on the rear elevation. Staff finds that these
openings reflect the pair of French Doors approved on the kitchen rather than the window patterning on the
historic house. Despite the fact that the openings are on the back, they do impact the architecture of the
house because of the modern look of the openings. This house has individual punched windows, with the
exception of the paired windows on the first floor of the front and south gable ends. Staff recommends that
the opening pattern of individual openings, like the second floor of the front gable best reflects the historic
house and the window patterning of the building and are the most appropriate window pattern for the rear
addition. Changing a window to a door on each floor could then be acceptable. For this reason, staff
recommends that Option B with a window on each floor best follows the guidelines. Staff also recommends
that any new windows follow the guidelines and that any new doors are wood or fiberglass.
The relocation of a front door will impact the historic character of any historic building. For this reason, it is
rare to have included in an application. In this case, the applicant wanted to move the door from the side of
the porch (in the south facing wall) to the main wall of the porch which is west facing. The applicants felt that
the existing location didn’t work well with the space and the door was too narrow. Interior work on the house
uncovered historic framing that shows a door location in the west facing wall. There has not been an
investigation of the south facing door opening to determine if it was a historic opening or added only when
the west facing door was removed. Staff recommends approval of the relocation of the door to the west
facing wall sized to fit the historic framing. Since the south facing door is too narrow but is also a historic
door, staff recommends that the applicant salvage the door for reuse instead of sending it to the landfill. It
could be donated or sold if not reused on site. The new door submitted is a fiberglass door. It will not have
brickmold.
Staff finds that the porch repair work is appropriate as follows: floor replacement, if vertical-grained Douglas
fir tongue and groove flooring is used, the replacement of the steps with new steps that have closed risers and
a toe kick, and the installation of a new railing that follows the guidelines. The porch roof is scheduled for
repair but could also be replaced with a membrane roof.
Recommended Motion
Move to approve a Certificate of Appropriateness for the project at 638 South Governor Street as presented
in the application with the following conditions:

Applicant
Marek and Petra Sinagl
We are applying for a permit for the following parts
of our residential project:
1/ Addition
The proposed addition has 473 sqft in total, over
two levels. It extends the existing dwelling to the
back, without affecting the area of the front façade
visible from S Governor St. The shape of the
addition is designed based on consultations with
Jessica Bristow from the Historical Center. The
addition was also consulted with Marnie Teagle
to confirm that it meets all required setbacks. The
main general contractor hired to build the addition
is Eicher Design Build LLC. Other contractors are
specified in contacts.
2/ Deck
We would like to build a new backyard deck
adjacent to the existing kitchen. This deck will
connect the existing dwelling with the backyard.
3/ Fence
We are proposing to move the front privacy fence
line by approximately 16 feet to the front of the lot
— towards the main street. It will be approximately
55 feet from the front property line. It will be a
wood privacy fence hanging on posts. Foundation
will be 3’ 6” deep. We will maintain an entry gate in
that area.
4/ Porch
The existing front porch is in poor condition and in
need of repairs. We seek to replace wood flooring
boards as they deteriorate with newly painted
wood boards. The roof has significant deterioration
and the slope of the roof does not take rainwater
to the gutters. The current roof has a bitumen
surface which needs some repairs. As part of this
repair, we need to construct new stairs, which will
add one more riser to make it more comfortable.
We want to maintain the look of the front porch,
without making any significant alterations. Jim
Mahoney—a contractor recommended by Jessica
Bristow—is the main contractor hired for this job.
5) Door
We have uncovered that the location of the main
entrance door has originally been different (see
the attached photo documentation). We would
like to move the entrance door back to its original
location.
Should you have any questions regarding this
project, do not hesitate to contact Marek Sinagl
(319-259-2535) or Petra Sinagl (319-569-9502).
Sincerely,
Marek and Petra Sinagl

Staff Report May 4, 2022
Historic Review for HPC22-0020: 308 E Davenport Street
District: Contributing
Classification: Northside Historic District
The applicant, Michael McLaughlin, is requesting approval for a roof replacement project at 308 East
Davenport Street, a Contributing property in the Northside Historic District. The project consists of the
removal of the metal roof and its internal gutters and the replacement with architectural asphalt shingles and
external gutters.
Applicable Regulations and Guidelines:
4.0 Iowa City Historic Preservation Guidelines for Alterations
4.6 Gutters and Downspouts
4.7 Mass and Rooflines
Staff Comments
This two-story house was built between 1906 and 1912. It is a modified Foursquare or a transitional style
from Victorian cottage to Foursquare. The house consists of a two-story house with a hipped roof, a full-
width front porch, front and side projecting gables with fish scale siding and a one-story rear addition. The
house has a standing seam metal roof with integral gutters and asbestos siding. The porch columns, floor,
railing, stairs and skirting have all been replaced. On the second floor, under the front projecting gable,
modern casement windows are installed. At the time of the 1998 survey, the window was an overly large
eight-over-eight double-hung window. The front door has been blocked down to accommodate a shorter
door.
The applicant is proposing to replace the roof because it is deteriorated. The applicant is proposing removing
the metal roof and installing architectural asphalt shingles. During the project, the internal gutters, located
part way up the roof slope will be removed. While the roof replacement could be approved by staff as a
minor review, the removal of the internal gutters requires Commission approval.
The guidelines recommend in Section 4.6 Gutters and Downspouts to repair original built-in gutters. The
section states that Original built-in gutters are important design features of some historic buildings. Removing
them requires a building permit and must be approved by the HPC. Covering original built-in gutters and
applying exterior gutters may be approved only if the roof slope at the gutter is not altered. An exception
exits for the Commission to consider approval of the removal of the built-in gutters, when it does alter the
roof slope, if documentation is provided to establish evidence of need.
Section 4.7 Mass and Rooflines recommends maintaining metal roof rather than replacing them. It further
recommends that if quality replacement items cannot be obtained, metal roofs should be replaced with a
high-quality wood shingle or with asphalt shingles. It is recommended to use asphalt shingles that resemble
the texture and color of weathered wood shingles for roofs that had wood shingles historically.
In Staff’s opinion, this metal roof is deteriorated. Rusty areas are found throughout, especially in the valleys.
The gutters have been leaking into the soffits in a few places. This house originally had a wood shingle roof.
The metal was installed in the early 1920s. Since the house originally had a wood shingle, staff recommends
approval of an architectural asphalt shingle or a new standing seam metal roof.
Currently, staff has not located a way to construct this type of internal gutter in a new material that is not cost
prohibitive. Historic metal roofs are often a lead and zinc coated iron called Terne. The new version of terne
metal is a lead coated copper or stainless steel, both of which are cost-prohibitive. Common metal roof
products do not have a pre-formed internal gutters like the existing roof. Custom made products are unlikely
to perform like the original configuration.
At this time, staff does not see an alternative to removing internal gutters installed in the slope of the roof
when the roof is deteriorated beyond repair. In this case, the metal roof would be removed and asphalt
shingles installed. External gutters, held by brackets because of the sloping facia will be installed. Staff
recommends approval of the project.
Recommended Motion
Move to approve a Certificate of Appropriateness for the project at 308 East Davenport Street as presented
in the application.

PUBLIC DISCUSSION OF ANYTHING NOT ON THE AGENDA:
There was none
CONSENT AGENDA: CERTIFICATE OF APPROPRIATENESS:
1110 East College Street
Bristow described the house as being a two-story gable-roofed cottage in the East College
Historic District. There is a screened porch addition on the back of the building. The proposed
project is to remove the porch and replace it with a one-story addition to serve as a
multipurpose room with a bathroom. The owner is committed to matching the addition to the
house, and that sustainable practices are used in the build. The addition will be set in from the
corners of the house, with a pair of windows on the west side, a triplet of windows that match
those on the front of the house, a smaller window, and an entry stoop. The siding and trim will
match the lower level and the foundation will match the existing foundation. The addition is
designed to mimic the roof on the front porch. All materials will be wood to match the house.
The window and door products still need to be approved, but staff is confident that this will not
be a problem. There will be an accessibility lift attached to the rear stoop. The railing will match
the rest of the project.
Boyd invited the applicant to speak about the project and Bu Wilson came forward. She stated
that she and her husband want to retain the character and fit of the neighborhood.
MOTION: Sellegren moved to approve a Certificate of Appropriateness for the project at
1110 East College Street as presented in the application, on the condition that the door
and window products are approved by staff. DeGraw seconded the motion. The motion
carried on a vote of 7-0 (Beck, Larson, Wagner absent).

109 and 119 East College Street
Bristow stated that the project is for signage on the Tower Addition at 109 East College. She
noted that the sign code calls for no more than 90 square feet and must be a set percentage of
the wall space. Three signs are being proposed, and all are aluminum with white polycarbonate
base letters. They all meet the requirements of the sign code so city staff recommends
approval.
MOTION: DeGraw moved to approve a Certificate of Appropriateness for the project at
109 East College Street as presented in the application. Sellegren seconded the motion.
The motion carried on a vote of 7-0 (Beck, Larson, Wagner absent).
CONSENT AGENDA: MONTGOMERY BUTLER HOUSE
Boyd said this is the 3rd conversation about this building. He stated that he spoke with the Parks
and Recreation Commission, and they supported a working group to make decisions about this
property. He gave a brief history of the property and asked for support to take this
recommendation to City Council.
MOTION: Thomann moved to approve the memo about creating a working group to
explore the uses of the Montgomery Butler House as written. Brown seconded the
motion. The motion carried on a vote of 7-0 (Beck, Larson, Wagner absent).
CERTIFICATE OF NO MATERIAL EFFECT:
1113 East College Street
Bristow stated that this property has a barn garage in the back. There are water issues, so the
foundation needs to be replaced. Staff recommended a slight curb to mitigate future water
problems.
422 Brown Street
The front of the house has an enclosed porch, and an apartment with a basement patio. The
poured concrete retaining wall will be replaced with concrete block. Bristow added that owners
were informed that the railing will need to meet the guidelines if it is reconstructed.
1027 East College Street
Bristow said this is a roof replacement.
505 Clark Street
Bristow said this property has an historic garage. The door is being replaced along with other
repairs.
111 East College Street:
This is a minor alteration to an approved project. Bristow said there is a pair of solid steel doors
they had planned to keep but were found to be rusted through. They will be replaced with a pair
of doors that match another set that was already approved. The entry to 109 E College will also
be changed with a door instead of an entry alcove.
