by ordinance to be transmitted to the City Council

REPORT 2021
5ADU ANNUAL REPORTWHAT IS AN ADU?
An accessory Dwelling Unit is a complete, secondary residential unit that can be added to
a single family residential lot. ADUs can be attached to or part of the primary residence or
be detached as a separate building in the backyard. ADUs are often referred to as mother-
in-law apartments, backyard cottages, granny flats, and alley way cottages, detached
dwelling units, and many other similar terms.
WHERE CAN THEY BE LOCATED IN SLC?
An ADU may be located on any property that is zoned for single family dwellings and where
a single family home is on the same property. An ADU is not allowed when the property
already contains a duplex, triplex, or an apartment building.
HOW ARE ADUS APPROVED?
ADUs can be approved in the City through two different ways. First, if the property is in a
zoning district that already allows multiple units on a single lot, an ADU can be built as a
permitted use. A permitted use does not require any special approval process and can be
built after a building permit is issued. Second, if the property is in a single family zoning
district, an ADU can be approved as a conditional use. A conditional use requires a public
process that includes a 45 day public comment period followed by a public hearing with
the Planning Commission. Utah legislature adopted a law that makes ADUs a permitted
use when they are internal or attached to a single-family dwelling.

PERMITTED USE ADUS
An ADU is considered a permitted use in zoning districts that allow housing types that include
at least a duplex, but may include triplexes and apartments as well. This includes the SR-1A,
SR-3, R2, RMF, RMU, and MU zoning districts. The review process of permitted ADUs start
with submitting a building permit.
CONDITIONAL USE ADUS
ADUs in single family zoning districts require a conditional use. A conditional use requires a
public process that includes a 45-day public comment period followed by a public hearing
with the Planning Commission. The Planning Commission makes the final decision on ADUs
that require a conditional use.
WHERE ARE THE ADUS LOCATED?
The ADUs are located throughout the City. The map below shows the location of each
ADU application.
