CARMEL PLAN COMMISSION
-MEMORANDUM-
Date: June 26, 2020
To: Residential Committee
From: Adrienne Keeling
Re: Docket No. 19090013 OA
Enclosed is the information packet for the following item. If you have any questions, please call 571-2417.
Docket No. 19090013 OA: Accessory Dwelling Units Ordinance Amendment.
The applicant seeks to amend the Unified Development Ordinance in order to establish standards and
minimum requirements for Accessory Dwelling Units and to amend definitions. Filed by the Department
of Community Services on behalf of the Carmel Plan Commission.
Proposed Amendment Summary:
The number of questions raised at the public hearing were appreciated and show the complexity of the subject
matter. As we continue research, the concerns raised have certainly been noted; however, we have not
prepared any revisions in advance of the committee meeting. We would rather use the committee time to
gain further direction on possible revisions. As a reminder, the attached ordinance proposes the following:
1. Allow accessory dwelling units by right in residential zoning districts.
2. Establishes standards for accessory dwelling units for those adding an accessory dwelling to their
property.
3. Requires 20% of new lots developed in new subdivisions (10 or more lots of 1 acre or less in size) to
include an accessory dwelling.
4. Revises definitions related to Group Homes to include quantities and to remove outdated references to
Indiana Code.
What is an accessory dwelling unit, or ADU? Sometimes known as accessory apartments, carriage
houses, in-law suites, or granny flats; they are smaller, independent residential dwelling units, attached to,
within, or located on the same lot as a single-family home.
Topics/Questions from Plan Commission Hearing: Several questions were raised at the Plan Commission
Hearing, and some were answered briefly. Below are more elaborate responses to some topics raised.
Zoning Standards: Any proposed ADU would be required to comply with the established setback,
heights, maximum lot coverage standards of the zoning district, whether constructed within, in addition
to or detached from a single-family home. Currently there are no standards for accessory dwellings,
and in most districts would require BZA approval, leaving each proposal to be reviewed on a case-by-
case basis.
Building Code: Any proposed ADU would be required to comply with the same building, life and safety
standards as other residential structures, such as proper egress, handrails, doorways, smoke
detectors, insulation, etc.
ONE CIVIC SQUARE CARMEL, INDIANA 46032 317/571-2417
Density Calculation: ADUs were specifically excluded from density calculations for the following reasons:
1. Density expressed as the number of units per acre provides little indication of the character of a
neighborhood. For example, a maximum density of 1 unit per acre does not indicate that each lot
contains 1 acre – in fact, each lot could contain less than ½ an acre when balanced with streets,
perimeter landscaping, drainage, open space and common areas. Lot sizes, setbacks, landscaping
and sizes of homes are more indicative of a neighborhood’s pattern. With the ability of ADUs to
exist discreetly within, attached to, or detached from a single-family home, we don’t believe that
including them in the calculation them would provide any benefit.
2. It is not practical to calculate and track the gross density in an existing subdivision. This could have
the effect of allowing the first X number of accessory dwellings in a subdivision, then would each
ADU thereafter need to seek a variance from the maximum density of that zoning district?
3. Regarding new subdivisions, calculating ADUs into the subdivision’s density would limit the number
of lots allowed by 20% in exchange for providing the ADUs – a definite disincentive. This would only
serve to raise the cost per lot of providing the street and utility infrastructure that is so costly for new
developments.
Utility Capacity: Carmel Utilities believes that the water capacities estimated per residence are sufficient
to absorb additional usage of potential accessory dwellings due to their limited size. Any new service
lines to ADUs can be metered separately but will be required to connect through the main residence’s
service rather than additional separate connections to utility mains.
Other Cities: We researched and compared ten cities’ standards for accessory dwellings, and from those
we chose and drafted standards that we believe to be the best fit for Carmel. The cities were:
− Santa Cruz, California
− Norwalk, Connecticut
− Boise, Idaho
− Oahu, Hawaii
− Manhattan, Kansas
− Minneapolis, Minnesota
− Portland, Oregon
− Madison, Wisconsin
− Austin, Texas
− San Marcos, Texas
20% Requirement on New Subdivisions: There were several concerns expressed with the requirement
for accessory dwellings in new development. Generally, the concerns can be divided into two
categories:
− Market/Consumer Choice is something that DOCS takes seriously. Up to 80% of new single-
family lots can be developed using the same housing options that are currently available in the
Carmel market. However, Carmel has a history in leading the market in new directions, such as
restricting standalone retail along the Meridian Corridor in an effort to focus on employment, or
to require buildings to be built at the street (moving parking lots behind or below) to focus on
walkability, and to establish minimum building heights in certain areas to more efficiently use
building sites and promote walkability.
− Unintended Results such as a further decrease of affordability, increasing of new lot sizes to
avoid the requirement, and the location of new development areas further from walkable
amenities.
Group Homes: Additional information from John Molitor and a copy of a 2018 federal court decision will be
distributed with the Department Reports in advance of the Residential Committee meeting.
I look forward to further discussion with the Residential Committee on July 7th!

ORDINANCE Z-6XX-20 3
AN ORDINANCE OF THE COMMON COUNCIL OF THE 4
CITY OF CARMEL, INDIANA 5
___________________________________________________ 6
An Ordinance establishing standards and minimum requirements for Accessory Dwelling Units 7
in the Unified Development Ordinance. 8
9
Synopsis: 10
This ordinance amends the Unified Development Ordinance in order to establish standards and minimum 11
requirements for Accessory Dwelling units and to amend definitions related to dwellings. 12
13
WHEREAS, the City wishes to promote housing options to help meet the needs and preferences of all 14
residents. 15
WHEREAS, the U.S. Census Bureau reports in 2018 that the number of households across Clay 16
Township with one or more people over the age of 65 has grown to over twenty-five percent, with a median 17
age of over 41.3 years. 18
WHEREAS, a recent Housing Needs Assessment created for HAND reports the median closing price 19
on existing single-family homes in Carmel to be $360,720, with a median new construction price at $543,958, 20
both of which significantly outpace the overall Hamilton County prices of existing and new homes of $269,329 21
and $372,381, respectively. 22
WHEREAS, a 2018 housing study commissioned by MIBOR and BAGI revealed several key findings 23
related to housing in the Indianapolis Region over the next 20 years (2018-2038), including: 24
• The Indianapolis Region is projected to gain over 274,000 net new jobs over the next 20 years, 25
with Marion and Hamilton Counties expected to see the highest growth, driving demand for new 26
housing units. However, most of the industries projected to account for more than half of the 27
Region’s economy by 2038 offer median wages that would not allow single-earner households 28
to afford an existing home 29
• The Indianapolis Region is projected to underbuild each year by 1,750 units, and that recent 30
construction trends won’t meet the demand for a projected 9,000 new housing units annually 31
over the next 20 years. The study indicates Hamilton County’s share of that needed supply at 32
45,213 new housing units over the same time period. 33
• There is an inverse relationship between new construction prices and the incomes needed to 34
support them. Homes are being built at the high end, while below median wage households are 35
increasing. 36
• An underproduction of housing affects the entire economy, emphasizing that simply building 37
housing is not enough to support and sustain economic growth. New housing needs to be in the 38
right locations, of the right types, and at the right prices and rents to support both the workforce 39
and local municipalities. 40
WHEREAS, accessory dwelling units – or ADUs – are smaller, independent residential dwelling units 41
located on the same lot as a single-family home, and are known by other names, including accessory apartments, 42
carriage houses, in-law suites, and granny flats. 43
WHEREAS, accessory dwelling units were a common feature in single-family housing in the late 44
nineteenth and early twentieth century, providing additional housing for farmers, workers, tenants and extended 45
families. With the rise of lower-density suburban single-family subdivisions following World War II, accessory 46
06/05/2020
Accessory Dwelling Unit Ordinance Draft
2
dwellings were ultimately prohibited by most local jurisdictions with the adoption of residential zoning codes 47
which typically allowed only one home per lot, regardless of the home type or acreage with no exceptions. 48
WHEREAS, the traditional accessory dwelling unit can play a role in serving a housing need, and 49
according to AARP is reemerging as an affordable and flexible housing option that meets the needs of young 50
couples who want a small footprint to seniors looking to downsize but remain in their neighborhood. AARP 51
surveys consistently show that the vast majority of people age 50 or older want to remain in their homes and 52
communities as they age rather than to relocate. A 2018 Home and Community Preference Survey revealed that 53
people age 50-plus who would consider an accessory dwelling would do so in order to: 54
• Provide a home for a loved one in need of care, 55
• Provide housing for relatives or friends 56
• Feel safer by having someone nearby 57
• Have a space for guests 58
• Increase the value of their home 59
• Create a place for a caregiver to stay 60
• Earn extra income from renting to a tenant. 61
WHEREAS, according to the Urban Land Institute, accessory dwelling units can serve as a source of 62
financial stability, especially for seniors and others living on fixed incomes. Rental income from an accessory 63
dwelling unit can help defray rising costs of home ownership, allowing them to stay in their home and 64
neighborhood. 65
WHEREAS, because accessory dwelling units are smaller and use previously developed spaces such 66
as basements, upper floors or back yards, they tend to be more affordable than regular residential units in the 67
same neighborhood. 68
WHEREAS, accessory dwelling units preserve the character of new and established neighborhoods 69
because they can be created in many different shapes and styles. Accessory dwelling units can fit discreetly 70
into many development patterns, including suburban subdivisions, urban neighborhoods, and larger lot estates. 71
WHEREAS, accessory dwelling units efficiently use the City’s existing infrastructure and housing 72
stock in comparison to a new 200-unit apartment building. They bring additional housing to an area organically, 73
reducing the amount of new infrastructure needed to accommodate it. 74
WHEREAS, pursuant to Indiana Code 36-7-4-602 the Common Council is authorized to amend the 75
text of the unified development ordinance; and 76
WHEREAS, pursuant to Indiana Code 36-7-4-610 and City of Carmel Ordinance D-2391-17, the 77
Carmel Unified Development Ordinance is incorporated by reference into the Carmel City Code; 78
NOW, THEREFORE, BE IT ORDAINED by the Common Council of the City of Carmel, Indiana, 79
that, pursuant to IC 36-7-4-600 et seq. and after Docket No. 19090013 OA having received a ___________ 80
recommendation from the Carmel Advisory Plan Commission on Tuesday, ____________, 2020, it hereby 81
