Ordinance Amending Chapter 20, Chanhassen City Code, Accessory
Structures
EXECUTIVE SUMMARY
The City has received complaints regarding the construction of "carports" consisting of a
frame made of metal tubing and a plastic cover. In following up on these complaints, it
was discovered that our code has no regulation/restriction on materials permitted in the
construction of accessory structures in residential districts. Staff is recommending
adoption of an ordinance amendment to address this issue.
DISCUSSION
Temporary storage structures made of non-rigid materials are not designed to withstand
snow load levels produced by a Minnesota winter or heavy wind gusts. If temporary
structures were anchored to the ground with cement or bituminous, they could become a
permanent problem. However, certain types of accessory structures and patio furniture are
exempt from this ordinance. The use of the following types of accessory structures, when
used as designed, shall be exempt from the restrictions of Chanhassen City Code Section
20-904 (d). The following are examples of structures not prohibited by the ordinance:
Vinyl Storage Shed
Wooden Storage Shed
The City of Chanhassen . A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play.

Accessory Structures Ordinance Amendment
April 11 , 2005, Page 3
The storage of motor vehicles, recreational vehicles, or contracting equipment and materials in temporary
storage buildings made primarily of canvas, plastic fabric or other similar non-rigid materials shall be
prohibited. The following are examples of temporary storage structures that shall be prohibited under
Chanhassen City Code Section 20-904 (d):
Plastic Enclosed Canopy/"Carport"
Plastic Canopy
By amending the ordinance, staff will be able to control the type of accessory structures permitted within
Chanhassen more efficiently. The proposed changes regulate and restrict the type of materials permitted in the
construction of accessory structures. This addition to the zoning ordinance will protect neighboring property
values and preserve the aesthetic of residential neighborhoods by preventing the construction of unsightly
structures. All structures existing before adoption of this ordinance shall be grandfathered in as legal non-
conforming structures.
POTENTIAL DIFFICULTIES
Staff discussed potential difficulties in enforcement of this code and agreed on the following:
. Proof of a legal non-conforming status (i.e. date structure was originally erected)
. Dual use of a temporary structure (i.e. recreational shade tent/vehicle storage, greenhouse/contractor
storage, etc.)
ACTION REQillRED
City Council approval requires a simple majority vote of City Council present.
PLANNING COMMISSION SUMMARY
The Planning Commission held a public hearing on January 18,2005, to review the proposed ordinance
amendment. The Planning Commission voted 6 to 0 to approve the proposed amendment. The verbatim minutes
are attached.
RECOMMENDA TION
Staff and Planning Commission recommend that the City Council adopt the attached ordinance for Chapter 20
of the Chanhassen City Code, Accessory Structures.

SUBJ:
Code Amendment to Chapter 20-904 to Regulate Accessory
Structures
INTENT
Amend Section 20-904 (Accessory Structures) of the City Code. By amending
the ordinance staff will be able to regulate the type of accessory structures
permitted within Chanhassen more efficiently.
BACKGROUND
The City has received complaints regarding the construction of a "carport"
consisting of a frame made of metal tubing and a plastic cover. In following up
on these complaints it was discovered that there was little that could be done to
resolve the issue. The reason for this was that our code has no concrete
regulation/restriction on materials permitted in the construction of accessory
structures.
CHANHASSEN CITY CODE
City Code 20-1 defines structures as:
Accessory use or structure means a use or structure subordinate to and serving the principal
use or structure on the same lot and clearly and customarily incidental thereto.
Sec. 7-62. Exterior property areas
(g) Accessory structures. All accessory structures, including detached garages, fences and walls,
shall be maintained structurally sound and in good repair, and the garage shall be the same
color as the principal structure.
Sec. 20-904. Accessory structures.
(a) A detached accessory structure, except a dock, shall be located in the buildable lot area or
required rear yard. No accessory use or structure in any residential district shall be located in
any required front, side or rear setback with the following exceptions:
(1) In the RSF and R-4 Districts accessory structures shall not exceed one thousand (1,000)
square feet. These structures may encroach into the rear setback as follows:
a. Less than one hundred forty (140) square feet, minimum rear setback is five (5) feet.
b. One hundred forty-one (141) to three hundred ninety-nine (399) square feet,
minimum rear setback is ten (10) feet.
c. Four hundred (400) square feet and above, minimum rear setback is thirty (30) feet.
The City of Chanhassen · A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks A great place to live, work, and play.

(2) On riparian lots, detached garages and storage buildings may be located in the front or rear yard but must
comply with front, side and applicable ordinary high water mark setbacks and may not occupy more than
thirty (30) percent of the yard in which it is built.
(3) Tennis courts and swimming pools may be located in rear yards with a minimum side and rear yard setback
of ten (10) feet, but, must comply with applicable ordinary high water mark setbacks.
(b) A detached accessory structure may occupy not more than thirty (30) percent of the area of any rear yard.
(c) For parcels with less than three (3) acres in any residential or agricultural district, no accessory structure or use
shall be erected, constructed, or commenced prior to the erection, construction, or commencement of the
principal permitted structure or use, but may be erected or commenced simultaneously. If the principal structure
or use is subsequently removed, destroyed, or discontinued, the accessory structure or use must be removed or
discontinued within twelve (12) months.
FINDINGS
In researching city codes and speaking with planners from various municipalities in the Twin
Cities metropolitan area to see how they handle such situations, staff found that both definition
and regulation of temporary structures varied with each city. Some cities did not even define
temporary structures. Most cites included in the study had regulations on temporary structures
that were no stronger than ours, if they had any at all. However, staff was able to find some
definitions and regulations that could be helpful to the City of Chanhassen.
The Champlin City Code could be helpful in addressing situations similar to the "carport"
complaint discussed above. That ordinance reads as follows:
Building Materials
All accessory buildings in excess of one hundred twenty (120) square feet shall be constructed with a color
and exterior surface material consistent with the principal structure on the lot. Accessory buildings
constructed primarily of canvas, plastic fabric or other similar non-rigid materials, as determined by the
Building Official, shall be prohibited.
Staff recommends the Planning Commission adopt an ordinance that would allow the City to
regulate and restrict the type of materials permitted in the construction of accessory structures.
This addition to the zoning ordinance will protect neighboring property values and preserve the
aesthetic of residential neighborhoods.
If the City adopted the accessory structure materials ordinance, then all existing accessory
structures made of prohibited materials will become legal non-conforming.
RECOMMENDA TION
Amend Section 20-904 (Accessory Structures) of the City Code by adding subsection (d) to read
as follows:
(d) Accessory buildings constructed primarily of canvas, plastic fabric or other similar non-rigid materials,
as determined by the Building Official, shall be prohibited. Accessory structures shall be built of
materials compatible and comparable to those of the principle structure.
ATTACHMENTS
1. Ordinance Amendment.

EXCERPT PLANNING COMMISSION MINUTES - JANUARY 18, 2005
PUBLIC HEARING:
CODE AMENDMENT TO CHAPTER 20-904 TO REGULATE ACCESSORY
STRUCTURES.
Josh Metzer presented the staff report on this issue.
Sacchet: Questions from staff. Kurt.
Papke: Yeah, what affect would this have on greenhouses? It's possible to construct a
greenhouse with non-rigid windows in the greenhouse. Would this in effect bar that kind
of greenhouse construction?
AI-Jaff: Greenhouses are typically in nurseries.
Papke: But I could put one in my back yard.
AI-Jaff: Yes you could.
Sacchet: There are residences that have greenhouses attached. I mean that's.
AI-Jaff: Technically, yes.
Sacchet: So it could not be made out of plastic. It would have to be made out of glass.
Metzer: Some rigid material.
AI-Jaff: Unless you want to make an exemption for temporary plantings related
structures.
Sacchet: Any other questions? This is a, yes. Jerry, go ahead.
McDonald: Yeah, for just a clarification. Okay, docks and those things are exempt, the
way I read this as part of a, it looks like 904(a). It does say docks on lakes would be
exempt. So if I put up a structure there for a boat and everything to go into, which is one
of these canvas type structures, that is exempt? Am I correct in that?
AI-Jaff: Correct.
McDonald: Okay.
Metzer: We made a provision for that.
Sacchet: Any other questions for staff? No? This is a public hearing. Anybody want to
speak up to this item, please come forward now. Seeing nobody I close the public
hearing and bring it back to commissioners for discussion, comments. Where do we go
with this? No more greenhouses out of plastic.
