New Business:
Consider a Site Plan from C & O Real Estate LLC for a new dental office building on W. Bell
Avenue (Parcel IDs: 1070800610 & 1070800615)
Nathan Parch reported on the site plan for a 4,870-square foot dental office building on
W. Bell Avenue. A formal address for the property has not yet been assigned. Applicant C
& O Real Estate LLC have a purchase agreement pending for the property with owner
Ridge Development LLC.
The property is currently vacant, undeveloped land comprised of two parcels that
together form a “flag lot” totaling 275,212 SF (6.32 acres). In terms of the site plan design,
Parcel 1 will serve as the point of access connecting W. Bell Avenue with Parcel 2 where
the dental office building and parking will be located. Access will be provided by a 24-
foot- wide paved driveway leading to two parking areas adjacent to the north and east
facades of the building. The dental office building and parking areas will be positioned in
the eastern portion of Parcel 2; the western portion will be vacant.

Existing utilities are available to serve the development site except for a sanitary main.
Nearby properties (Knoxville Vet Clinic and Raceway Tire) utilize septic systems at this time.
Ridge Development LLC intends to install a private sanitary system with lift station that will
connect to the City’s sanitary main to the north near Eric Drive in order to service this site
and others under their control. Ridge Development LLC is currently in negotiations with the
City to establish a Tax Increment Financing District and Development Agreement to assist
with development related costs, including the lift station.
While members of the Planning and Zoning Commission were supportive of the project
overall, they did raise concerns about the proximity of the proposed site entrance on W.
Bell Avenue to the adjacent intersection. Commissioners recognized that alternate points
of entry to the subject site may be feasible and should be explored further, but they did
not want to halt the project from moving forward. In lieu of an alternate point of entry
being secured, Commissioners acknowledged that the proposed entrance, while not
ideal, could function with the expected low traffic demand generated by a dental office.
They were also supportive of City Council initiating future study and evaluation of the W.
Bell Avenue and Hwy 14/S. Lincoln intersection in recognition that it be able to
accommodate future development in the area.
Motion was made and seconded to approve the site plan subject to the following
condition:
1) Consideration be given to evaluating alternate points of entry to the subject site.
Motion approved on voice vote:
Ayes: Cox, Swayne, Meyers, Ziller; Nays: None; Absent: Vander Ecken, Young.
Consider an application from Jeff Sinnard to rezone the properties at 1506 and 1510 E
Marion Street from C-2, General Commercial, to M-1, Service Commercial/Limited
Industrial District
Nathan Parch reported on the request to rezone two adjacent properties from C-2,
General Commercial, to M-1, Service Commercial/Limited Industrial District, both located
on the south side of E Marion Street, east of the point where Marion and the railroad tracks
intersect. A vacant single-family home is located on the 1510 E Marion property and the
1506 E Marion property is not developed. The applicant/owner intends to convert the
vacant structure for use as a garage and shop.
This particular block of Marion Street is a one-lane gravel road with a non-signaled railroad
crossing and a steep hill at the west end. There are no known plans to widen or pave this
section of roadway. Adjacent properties to the east – 1514 and 1610 E Marion – were

Consider Final Plat from the City of Knoxville for The Veterans District Plat One Subdivision
Nathan Parch provided a summary of the final plat for The Veterans District Plat 1
subdivision, which would include lots 1-34 for residential development, the 3.4-acre
Veteran’s Park (Outlot V), a 2.5-acre stormwater detention area (Outlot Z), public streets -
Veteran’s Boulevard, Freedom Way, Liberty Lane, and Justice Way, and public alleys to
serve all lots. Mr. Parch reported that the final plat prepared by Snyder & Associates, Inc.,
1
PLANNING & ZONING COMMISSION
MINUTES
November 8, 2022
dated November 4, 2022, conformed with both the preliminary plat and the design
principles of the PUD master plan for the 21.58-acre development approved in July 2022. It
was noted the preliminary plat included 68 total lots and a larger footprint, however the
intended number of lots at this time would be 34 with future phases planned to increase
the number of lots to 68.
Kirsten Meyers inquired about parking for Veterans Park being that there is no designated
parking area shown on the plat.
Glenn Lyons responded that parallel street parking would be available along the built
portions of Justice Way, Freedom Way, and Veteran’s Boulevard. Depending on demand,
the city could consider temporary measures for additional parking until such time Justice
Way is extended and Barton Drive is built along the west boundary of the park.
Mr. Lyons noted that amendments to the 2020 Concept Plan for the Veterans District are
likely in the future as development begins and will be undertaken with the review and
involvement of the Planning & Zoning Commission moving forward.
Motion was made by Mike Cox to approve the final plat for The Veterans District Plat 1
subdivision as presented. The motion was seconded by Scott Ziller. Motion approved on
roll call vote:
Ayes: Cox, Meyers, Swayne, Ziller; Nays: Young; Absent: None
Consider Urban Renewal Plan for the 2022 Ridge Development Urban Renewal Area on W.
Bell Avenue
Nathan Parch explained that City Council initiated the process to establish a Tax
Increment Financing (TIF) District and Development Agreement with Ridge Development,
LLC to assist with specific infrastructure costs for the development of four parcels on W. Bell
Avenue that would include a dental office, private auto/race shop, and contractor
condo warehouse building. Preparation of an urban renewal plan is a required step in this
process.
The Urban Renewal Plan for the 2022 Ridge Development Urban Renewal Area, dated
November 2022, specifies that Ridge Development, LLC will undertake construction of a
private sanitary sewer and lift station necessary to serve the buildings in the project area.
The City’s anticipated total commitment through the use of TIF will not exceed $575,000.
The plan is required to be approved by City Council following a public hearing, which is
scheduled for November 21, 2022.

November 8, 2022
Mr. Parch stated that, prior to the November 21 public hearing, the Planning & Zoning
Commission is required to review the proposed plan as to its conformity and consistency
with the City’s existing comprehensive plan and zoning regulations and provide comment
to City Council as to such.
To that end, Mr. Parch provided an overview of Knoxville’s Comprehensive Plan, adopted
December 4, 2017, specifically as it pertains to future land use recommendations for the
project area. The plan identifies Agriculture as the future land use for the subject
properties. Mr. Parch explained this was likely due to the lack of utilities to service this
portion of W. Bell Avenue, the roadway cross section being rural with granular surfacing
not conducive to commercial development, and no public roadway or utility
improvements targeted for the area at the time the Comprehensive Plan was prepared.
Mr. Parch further noted that the subject properties are zoned for service
commercial/limited industrial, which is consistent with the uses/buildings proposed by
Ridge Development, LLC, and that commercial development has expanded into the area
since 2017 beginning with the establishment of Raceway Tire & Exhaust at 1318 W. Bell
Ave. in 2020. Members of the Planning & Zoning Commission concurred with this
assessment.
Motion was made by Lucas Young to inform City Council of the Commission’s finding that
the proposed Urban Renewal Plan is appropriate and consistent with the City of Knoxville’s
Comprehensive Plan and zoning regulations. The motion was seconded by Scott Ziller.
Motion approved on roll call vote:
Ayes: Cox, Meyers, Swayne, Young, Ziller; Nays: None; Absent: None
Motion was made and seconded to adjourn. Meeting adjourned at 6:10 pm.

SUBDIVISION OF DUPLEX AND ROWHOUSE DWELLINGS
SUMMARY
CASE NUMBER: N/A
PREPARED BY: Nathan Parch, Planning & Zoning Administrator
MEETING DATE: January 24, 2023 – Planning & Zoning Commission
February 6, 2023 – City Council
REQUEST: Consider possible amendments to the Knoxville Zoning Code Residential Districts
Ordinance relating to subdivision of duplex and rowhouse dwellings to
accommodate their sale to separate owners
BACKGROUND:
The City’s zoning code allows for multi-unit housing types such as duplexes and rowhouses to be built
on a single lot pending the lot meets the minimum area/width requirements of the district and the
building setbacks. However, our code lacks the specific regulations to accommodate individual
ownership of the dwelling units on individual lots despite having the definitions in place to permit this
type of ownership (see highlights below).
9-1-3: DEFINITIONS:
• Dwelling, Condominium: A multiple dwelling where the fee title to each dwelling unit is held
independently of the others.
• Dwelling, Multiple-Family: A building or portion thereof designed for or occupied exclusively by
three (3) or more families.
• Dwelling, Single-Family Attached: Two (2) or more single- family dwellings sharing common wall
areas, each on its own individual lot.
• Dwelling, Two-Family: A building designed for or occupied exclusively by two (2) families with
separate housekeeping and cooking facilities.
• Rowhouse: Three (3) or more attached single-family dwellings, each on its own plot of ground, but
not necessarily on individual lots.

Currently, if someone lawfully builds a duplex or rowhouse in Knoxville within the R-2 or R-3 districts
they own the entire building, as shown in the above example and the dwelling units may not be sold
for individual ownership.
The City’s lack of regulations in this area came to light recently with the duplex under construction at
501 S. Sixth Street (Lot 9 of the East Elementary Subdivision). The duplex structure is located on a single
lot, as permitted in the R-2 district, however the developer intends to sell each unit separately. Staff
recommended the developer file an application with the Board of Adjustment requesting variances
for lot area, lot width, and side yard setback in order to divide the single lot into two lots – one lot for
each unit. Staff advised the developer that the variance process was the only option currently
available, absent a zoning code amendment, for subdividing duplex and rowhouse dwellings to
accommodate their sale to separate owners.
On December 21, 2022, the Board of Adjustment considered an application from the developer -
Knoxville Economic Development Corporation (KEDC) - requesting three variances in order to
subdivide the property at 501 S. Sixth Street into two lots, thereby permitting individual ownership of
each dwelling unit within the duplex currently being built. See attached application and staff report.
The Board denied the application for variances by a 3-0 vote noting the hardship was created by the
actions of the applicant.
In advance of the Board of Adjustment meeting, staff presented the attached report – City Council
Letter – December 19, 2022 – to City Council on December 19, 2022 highlighting the City’s lack of
regulations for subdividing duplex and rowhouse dwellings and asking for direction on preparing a
zoning code amendment to address it. City Council unanimously approved a motion instructing staff
to initiate the amendment process with the Planning & Zoning Commission.
PROPOSED AMENDMENTS:
Many communities, nationally and locally, have requirements allowing for the units within a duplex
and/or rowhouse to be located on individual lots to accommodate their sale to separate owners
without necessitating the need to pursue zoning variances in order to do so. Staff confirmed
Indianola, Oskaloosa, and Pella have such requirements in place.
Pursuant to the City Council’s directive, staff prepared the attached outline – Zero Lot Line
Subdivisions for Single Family Attached Dwellings – that identifies what revisions are necessary to the
zoning code. A summary follows:
1) As noted in the above table, only “Two-Family Dwellings” are permitted uses in the R-2 and R-3
districts. Two-Family Dwellings are intended to be built on the same lot.
• Recommendation – Retain Two-Family Dwellings as permitted uses in the R-2 and R-3
districts as a housing type where the sale of units is not intended. (E.g. conversion of
one-family dwellings into two-family dwellings)
2) The zoning code does not list “Single-Family Attached Dwellings” as permitted uses in any of
the residential districts, despite having a definition (above) for this housing type.
3
• Recommendation – Add Single-Family Attached Dwellings as permitted uses in the R-2
and R-3 districts allowing for ownership of individual units on individual lots.
3) The zoning code requires side yard setbacks (7’ for two-family & 11’ for multiple-family), which
does not accommodate duplexes and rowhouses on individual lots that, by design, require a
zero-foot setback from the common (shared) lot line(s).
• Recommendation – Add a zero-foot setback from common lot lines for attached
residential structures only.
• Recommendation – Add definition for Zero Lot Line Development.
4) The zoning code lacks minimum dimensions for duplex and rowhouse dwelling units.
• Recommendation – Add minimum dimensions per unit as follows:
Interior Unit – 18 feet in width and 1,800 square feet
End Unit – 25 feet in width and 2,500 square feet
Define Interior Unit and End Unit
5) The zoning code lacks a defined process for subdividing duplex and rowhouse dwellings.
• Recommendation – Add an administrative process whereby the Planning & Zoning
Administrator has the authority to approve subdivisions of duplex and rowhouse units
pending the following:
The building conforms to the zoning code bulk regulations for the district;
The dwelling units conform to the minimum dimensions for width and area for
interior and/or end units;
A plat is provided showing the as-built location of the duplex or rowhouse
structure with each dwelling unit located exclusively on one lot, except for the
party wall that bisects the lot line;
An executed party wall agreement (see attached example) for each dwelling
unit is provided;
Each dwelling unit provides direct access at grade to the street; and
Each dwelling unit meets the minimum off-street parking requirements (2 spaces
per unit).

STAFF REPORT
DECEMBER 21, 2022
501 E. SIXTH STREET – VARIANCES
SUMMARY
CASE NUMBER: BOA-22-008
PREPARED BY: Nathan Parch, Planning & Zoning Administrator
MEETING DATE: December 21, 2022 – Board of Adjustment
REQUEST: Consider Variances to Lot Width, Lot Area, and Side Yard for Duplex at 501 S.
Sixth Street (Lot 9 of the East Elementary Subdivision)
PURPOSE: Subdivide Duplex in order to Sell Units Separately
SUMMARY OF REQUEST:
The City’s zoning code allows for multi-unit housing types such as duplexes and rowhouses to be built
on a single lot pending the minimum lot area and lot width requirements and building setbacks of the
district are met. However, the code currently lacks specific regulations to accommodate individual
ownership of the dwelling units. Therefore, if someone lawfully builds a duplex in the R-2 or R-3 districts
they own the entire building (both units) as shown in the below example.
Many communities allow for the units within a duplex and/or rowhouse to be located on individual
lots. This is typically permitted through specific regulations for each unit (versus each building)
regarding lot area, lot width, and internal side yards of zero feet. See below example.
In the absence of such requirements, the only option is to pursue a variance through the Board of
Adjustment in order to subdivide duplex and rowhouse dwellings to accommodate their sale to
separate owners. This came to light recently with the duplex under construction at 501 S. Sixth Street
(further information is below). The duplex structure is located on a single lot, however the developer
intends to sell each unit separately.
Staff provided an update to City Council on December 19, 2022 regarding the City’s lack of
regulations in this area - see attached Council Letter. City Council has since instructed staff to
prepare an amendment to the zoning code to better accommodate such divisions. City Council also
acknowledged that the subdivision of 501 E. Sixth Street would have to be addressed by the Board of
Adjustment in the interim.
Therefore, at this time Knoxville Economic Development Corporation (KEDC), requests three
variances in order to subdivide the property at 501 S. Sixth Street (Lot 9) into two lots, thereby
permitting individual ownership of each dwelling unit within the duplex currently being developed.
Dimensions for Lot 9 are 100’x150’ totaling 15,000 square feet in area. The lot division will follow the
centerline of the duplex structure resulting in Parcel A being 66.34’x150’ totaling 9,951 square feet
and Parcel B being 33.66’x150’ totaling 5,049 square feet. There is an existing 30-foot-wide public
utility easement located on Parcel A, which is why Parcel A is larger than Parcel B. A plat of survey
has been prepared by Garden & Associates, dated September 12, 2022, showing the subject
property, the current building foundation, and the proposed division into Parcel A and B.
This request necessitates the following variances:
1) Lot Width (Zoning Code Section 9-6B-5(B)) – The applicant requests the lot width be reduced
from 75 feet to 66.34 feet for Parcel A and 33.66 feet for Parcel B.
2) Lot Area (Zoning Code Section 9-6B-5(A)) – The applicant requests the lot area be reduced
from 7,200 square feet to 5,049 square feet for Parcel B only.
3) Side Yard (Zoning Code Section 9-6B-5(D) – The applicant requests the side yards adjacent to
the proposed property center line be reduced from 7 feet to 0 feet.

ANALYSIS OF REQUEST:
1) A variance from the Zoning Code shall not be granted by the board unless and until a written
application for a variance is submitted demonstrating the following:
a) That special conditions and circumstances exist which are peculiar to the land, structure or
building involved, and which are not applicable to other lands, structures or buildings in the
same district;
o The property has a 30-foot-wide public easement on its north side.
o The duplex building meets the R-2 zoning requirements and bulk regulations.
o In order to divide the parcel into two lots for individual ownership certain relaxations are
necessary.
b) That literal interpretation of the provisions of this title would deprive the applicant of rights
commonly enjoyed by other properties in the same district under the terms of this title;
o The zoning code allows duplex and rowhouse dwellings as permitted uses in its
residential districts, but lacks specific regulations to allow division of units for owner
occupancy.
3
o The property is zoned R-2 which has the following stated intent: “This district is intended
to provide for medium density residential development, characterized by single-family
dwellings on moderately-sized lots along with low density multi-unit residential structures
such as duplexes and townhouses. It provides regulations to encourage innovative
forms of housing development. It adapts to both established and developing
neighborhoods, as well as transitions between single-family and multi-family areas. Its
regulations are intended to minimize traffic congestion and to assure that density is
consistent with the carrying capacity of infrastructure.”
c) That the hardship has not been created by the actions of the applicant.
o The public easement is a longstanding feature of the former school yard.
o A duplex dwelling is a permitted use in the R-2 district.
o The zoning code does not define clearly a process by which city staff may approve the
division of a duplex lot to allow for separate ownership; Board of Adjustment review is
required.
2) The board shall make a finding that the reasons set forth in the application justify the granting of
the variance, and that the variance is the minimum variance that will make possible the
reasonable use of the land, building or structure.
3) The board shall make a finding that the granting of the variance will be in harmony with the
general purpose and intent of this title, and will not be injurious to the neighborhood or otherwise
detrimental to the public welfare.
PROCESS:
Notice of the public hearing appeared in the Marion County Express on December 16, 2022.
Additionally, owners of properties within 200 feet of the subject site were notified by mail.
ACTION:
The Board of Adjustment may choose one of the following four actions:
1. Approve the variance as presented (Staff Recommendation)
2. Approve the variance with conditions
3. Deny the variance
4. Table the meeting if more information is required

Council Letter
City of Knoxville
December 19, 2022
Agenda Item: Subdivision of Duplex and Row House Projects and the Zoning Code
Background:
The City of Knoxville’s Zoning Code does not specifically address the question of subdividing
duplex and rowhouse dwellings to accommodate their sale to separate owners. As it currently
stands, any such division must be brought forward to the Board of Adjustment for consideration.
While this may have been sufficient in a period when Knoxville had few duplex or rowhouse
projects; as the number of such projects increases it would be prudent to amend the Zoning Code
to allow the Planning & Zoning Commission to review such applications, instead of the Board of
Adjustment.
Duplex and rowhouses provide a cost-efficient ownership alternative to single family homes.
Over the years, such projects have been built throughout North America. Their appeal to
prospective purchasers has both economic and lifestyle dimensions.
Knoxville has not seen this form of development proliferate, which explains in part why there has
been no pressing need to update the Zoning Code. Now with the development of the first duplex
in East Village, and the expected development of both duplexes and rowhouses in the Veterans
District, there is a need to initiate this change.
The case of 501 6th Street in East Village provides an example. This is a 100’ wide lot that is zoned
R-2. It and another as yet undeveloped lot, at 500 7th Street, are to be built as duplexes. The
duplex at 501 6th Street is nearing completion and the developer, KEDC, must subdivide the lot
to legally separate the dwelling units in order to sell them.
The East Village subdivision was approved by City Council and the duplex building received a
building permit because it met the R-2 rules. When KEDC applies for subdivision of the duplex
parcel, however, neither of the individual units will meet the R-2 rules. For example, there will
be no side yards between the units and in the case of the south unit, the proposed lot will be less
than the R-2 minimum lot area and width.
KEDC is applying to the Board of Adjustment for a variance to subdivide 501 6th Street. Without
the variance, the units may not be sold separately.
2
Board of Adjustment review of such variance applications as a standard practice can act as a
disincentive to prospective developers, as the outcome would be perceived as less certain than
a standard review by the Planning & Zoning Commission. This is particularly the case given that:
(1) A hardship must be demonstrated by the applicant in order to receive approval from
the Board of Adjustment for variance. Cases for hardship need to be related to the
physical aspects of the property, and may not be personal or financial;
(2) The criteria included in the Zoning Code to guide the Board of Adjustment on
variances relate to special conditions and unique circumstances with the land,
structure, or building. Such conditions are not always present and at times may be
difficult to demonstrate; and
(3) Survey and subdivision of such lots generally occurs after the foundations are laid to
avoid foundation siting errors that would lead to encroachments.
City Council in its Comprehensive Plan and the Veterans District Land Use Strategy has clearly
expressed the need to promote a range of housing choices, including owner-occupied duplexes
and rowhouses. Comprehensive Plan Housing Goals and Objectives include the following:
Goal: To promote a range of housing choices…
Policies:
• Promote entry level and young family housing opportunities.
• Encourage the development of housing choices to fit retirees and the elderly and
develop ‘move-up’ opportunities (e.g., townhouse/condo with low maintenance).
• Support the development of a variety of multi-family housing types.
• Ensure that Knoxville provides diverse housing type options in relation to lot size,
price point, density, and the type of residential development.
Under Land Use & Growth Management, the Comprehensive Plan also has a policy to:
• Update city ordinances and subdivision regulations to accommodate development
in both the originally platted areas of town as well as more recently developed
areas.
3
The Veterans District Land Use Strategy, also approved by City Council, identifies organizing
principles for the District, which include providing for:
• A wide range of housing types, appealing to a diversity of households and
household incomes…
The proposed amendment to the Zoning Code would assign subdivision review of detached
dwelling units to the Planning and Zoning Commission. It would also provide a set of guidelines
for that review which would include but not be limited to the following:
• Ensuring that the individual lots and their respective units conform to a set of
minimum standards with respect to lot size;
• Ensuring that each of the dwelling units that would form separate lots have
entrances located at grade that face the street; and
• Ensuring the individual lots and their dwelling units meet the minimum parking
requirements.
Preparation of the amendment to the Zoning Code can be undertaken by City Staff and reviewed
by the Planning & Zoning Commission prior to proceeding to Council.
Policy Question: Should City Council instruct Staff to prepare an amendment to the Zoning
Code to better accommodate the division of duplex and row house lots for separate owner
occupancy?
Budget Impact: None. This work would be completed in-house by the Planning and Economic
Development Directors.
Recommendations: It is recommended that:
1. City Council instruct Staff to prepare an amendment to the Zoning Code to better
accommodate the subdivision of duplex and row house lots for separate owner
occupancy; and
2. City Council acknowledge that the subdivision of 501 6th Street in East Village will be
addressed by the Board of Adjustment.
Supporting Documents: None

Doing the math: East Village
The Existing R-2 Rules were applied to the duplex building.
The individual units, however, would require a minimum 25’ lot width (18’ + 7’ side
yard) and a minimum of 1800 SF per unit
In this case the minimum lot widths would be about 63 and 36’, and the lot sizes much
greater than the minimum
Doing the math – VA (3-unit Row House on 100’ lot)
The Existing PUD (R-2*) rules would apply to the row house building.
The end units would require a 25’ lot width and a 2500 SF lot size.
The interior unit would require an 18’ lot width and an 1800 SF lot size.
In the VA case, with 18’ wide units (they could be larger)
The two end units would be 41’ wide and the interior unit 18’ wide
The two end units would have a lot area of 4,510 SF, and the interior unit 1,980 SF,
Standard Row House Widths
18’ for a two-bedroom townhouse
24’ for a three-bedroom townhouse.
