From: Merritt Clapp-Smith, Planner
Date: August 7, 2019
SUBJECT: Proposed amendments to Accessory Structure standards – Section
3.2 of Chapter 2 of the Development Code of the City of Scandia
MEETING DATE: August 20, 2019
BACKGROUND INFORMATION
The topic of accessory structures and the number allowed on a single property has been
brought to the attention of the Planning Commission and City Council on a number of
occasions, most recently in regard to the number of structures allowed for sheltering animals.
Code standards for accessory structures have been altered a few times over the past 15 years.
In 2006, Ordinance 90 added design standards for accessory structures which were later
adopted into the general design standards in 3.14 Building Type and Materials. In 2013,
Ordinance 131 amended Ordinance 122 regarding Accessory Structures to slightly increase the
total square footage of structures allowed on 5.0 to 10.0 acre lots; added the provision that
attached or detached garages up to 24’ by 24’ would not be counted towards the maximum
number of accessory structures, but would count toward the overall maximum square footage;
and added exceptions for historic structures.
The Planning Commission discussed the current standards for accessory structures this spring
and decided to re-evaluate them in relation to the size and number of structures allowed,
particularly for smaller structures such as animal shelters, garden and tool sheds, and children’s
playhouses. After an August 6, 2019 public hearing on proposed amendments to standards for
Accessory Structures, the Planning Commission recommends the following ordinance
amendments.

PROPOSED AMENDMENTS
AN ORDINANCE AMENDING SECTION 3.2 OF CHAPTER 2
OF THE DEVELOPMENT CODE OF THE CITY OF SCANDIA
PERTAINING TO ACCESSORY STRUCTURES
The City Council of the City of Scandia, Washington County, Minnesota hereby ordains:
Sections 3.2 of Chapter 2 of the Development Code of the City of Scandia are hereby
amended as follows:
3.2 Accessory Structures
(1) Required Permits. A building permit is required for all accessory structures except the
following: 1) agricultural buildings as defined herein and 2) non-agricultural accessory
structures that are 150 120 square feet or smaller. An administrative permit is required for
all agricultural buildings and agricultural accessory structures.
(2) All Accessory Structures. The following standards apply to all accessory structures.
(A) No accessory structure shall be constructed on a lot prior to construction of the
principal structure on the lot.
(B) No detached accessory structure, including storage sheds, shall be located
closer to the road right-of-way in relation to the front lot line than the principal
building on a lot unless the following conditions are met:
1. The parcel is located on a lakeshore or on a riverfront in the Saint
Croix River District. Accessory structures on lakeshore or riverfront
parcels may be located between the roadway right-of-way and
principal building and shall meet setback requirements; or
RATIONALE: The building code requires building permits for any structure with a floor
area of 200 square feet or larger. Requiring a building permit for structures down to 150
square feet provides the city a mechanism to review the structure related to setbacks
and other standards.

2. The accessory structure is located on a lot of three (3) five (5) acres or
more and is placed at least 200 feet from the road right-of-way; or
3. The accessory structure is located on a parcel that is less than five (5)
acres in size, is necessary to meet the Exterior Storage requirements of
this Chapter, and the physical conditions on the parcel (including but
not limited to steep slopes, locations of wetlands, location of the
principal structure) prevent the location of the storage structure within
the side or rear yard; and
Permit required. The property owner shall submit a plan for the
proposed structure and obtain an administrative permit authorizing the
location of the structure in the front yard. The Zoning Administrator
may require screening if needed to protect views from adjacent
properties or public roadways.
4. In situations 1-3 above, all setbacks and impervious cover
requirements are met.
(3) Residential and Agricultural Accessory Structures. The following additional standards
apply to all residential and agricultural accessory structures:
(A) Accessory structures may not include a dwelling unit unless it meets the
standards of Section 4.2 Accessory Dwelling Units of this Development Code.
Accessory structures or portions of structures that meet the standards of
Section 4.2 may be rented or leased. Other accessory structures shall not be
rented, leased, or sold separately from sale of the primary single-family
dwelling on the lot.
(B) Accessory structure height is limited to the permitted building height in each
zoning district.
RATIONALE: Add river district reference, since it’s a comparable waterfront
condition to lakeshore for the purposes of building placement.
RATIONALE: Reduce minimum lot size this applies to, since a 3 acre lot is still
somewhat large.

RATIONALE: Proposed increases in the allowed number and total square footage of
accessory structures shown below protects the public interest of city residents, while
providing individual property owners a bit more flexibility to have accessory
structures on their property. Structures under 120 square feet are small enough to
have minimal impacts and therefore are recommended for exemption from the
overall number and size limit for accessory structures on a property.

* The lot size of parcels within Shoreland areas shall include only the area of the

** If the property has no attached garage, one detached garage up to 24’x 36’ in
size is permitted in addition to the number of accessory structures listed in Section
(C) above. This exception is intended to permit a garage only, and the square
footage of the garage may not be added to the number or square footage of
accessory structures that are permitted on the property by the table above. The
total area of structures including the garage shall meet the lot coverage
requirements. The property owner must demonstrate that there is adequate space
available on the parcel for a primary and secondary septic system that meet
Washington County SSTS ordinance requirements outside the area proposed for
the garage.
*** One single story shed of 120 square feet or less is permitted in addition to
the number of accessory structures listed in Section (C), above. Ice fishing
houses greater than 120 square feet that are stored on parcels of land during
non-winter months shall be deemed to be an accessory structure. the permitted
shed.

* One rural accessory structure to shelter domestic farm animals or to provide
storage for rural/farm uses is permitted on lots between 5.0 and 10.00 acres.

RATIONALE: The above reference to allowing one structure under 120 square feet is
no longer needed, since accessory structures under 120 square feet are proposed
for no regulation. The proposed code revisions are consistent with code Section
4.16(C) regarding coops.
RATIONALE: The above allowance is no longer needed since the number of
structures allowed on 5-10 acres lots is proposed to be greater.

than the primary structure, to permit the preservation of historic buildings and structures,
