RE Fire Code & Building Code Revisions
Ron Wasmund and Bernie Szczesniak have individually and jointly
considered the need to consider changes in the city code to cover the
use of charcoal grills on decks and patios and the sprinkling of certain
structures in the city all in consideration of tighter regulation of the
construction and use of buildings.
Both feel that the following should be done
(1) Adopt an ordinance prohibiting or restricting the use of outdoor
cooking grills on patio decks, balconies or rooftops in multiple
family dwellings.
(2) Adopt an ordinance, along the lines of the Uniform Fire Code, to
require the sprinkling of commercial, industrial and wood framed
multiple -family structures over two stories in height. Bernie has
suggested looking ,at requiring the sprinkling of residential
structures.
The "other issue brought up by both is that if these ordinances are
adopted, they must be accompanied 'by`enforcement language to insure that
requirements can be followed up on.
Please review the attached recommendations; and if the Council feels
this type of enforcement and regulation is warranted, we will put
together a draft of the code change needed.

SUBJ: FIRE ORDINANCES
I have reviewed and met briefly with Bernie Szczesniak to discuss the
proposed ordinance changes to the Fire Codes.
I feel very strongly that an ordinance regulating the use of outdoor
cooking devices is needed. The potential for disaster is very great
anytime a cooking grill is used on a patio deck, rooftop or balcony. When
these devices are used in multi -family structures neighbors are always at
the mercy of the carefulness and conscientiousness of the user. We have
been very fortunate to not have experienced any major loss in Rosemount
to date. That can be partially attributed to the fewmulti-family dwellings
existing. Now would be an excellent time to adopt such ordinance
resulting in relatively low impact to existing occupancies. I will work
closely with the fire department to establish definitions of decks, patios,
grade, multi -family, etc. as well as specific ordinance language.
I would also recommend that we adopt an ordinance or resolution requiring
sprinkler systems be installed in existing commercial,' industrial and wood
framed multi -family structures over two stories in height. In addition or
conjunction with the sprinklering I would like to see Appendix 1-A of the
1982 , Uniform Fire Code be adopted to amend Section 6-1-1- of the
Rosemount City Code, This appendix covers Life Safety Requirements for
all existing buildings. I have attached a copy of this for your information.
Items number II and III in Bernie's memo are needed hand in hand. To
determine compliance with the fire codes, inspections must be made. To
insure compliance is gained a method of follow through such as ticketing
must be defined by ordinance. I have attached section 6-1 of Rosemount
City Code. I don't find any specific mention of tickets, however 6-1-6
does address penalties.
Dean and I will be working with the City Attorney to outline a specific
citation policy and procedure for code violations, the Fire Code could be
addressed at the same time. Based upon the attorney's recommendations
the City may want to limit the ticketing powers to designated people such
as Building Official, Zoning Administrator, Fire Chief and Fire Marshal.
Fire Ordinances
July 15, 1987
While residential sprinklering would be ideal for the community as a whole
in terms of insurance ratings, the limited urban service area with
municipal water could create an enforcement nightmare since private wells
may not have sufficient supply or pressure to operate a system. I don't
think that residential sprinklering is practical at this time.
One more ordinance need comes to mind as I write this memo. I would
like to discuss the licensing and inspection of rental properties. Every
year it seems we get more and more properties which are being rented or
leased. Without trying to stereotype but enable to protect neighbors
safety and pride of ownership, annual licenses and inspections could bridge
a gap that now exists for occupied property.
All of these items will take careful consideration and time to draft. Twill
work closely with the fire department, the council and the attorney to
provide what I can in the form of model ordinances and building code
considerations.
Please keep me informed as developments occur.

ROSEMOUNT VOLUNTEER FIRE DEPARTMENT
ROSEMOUNT, MINNESOTA 55068
TO: BOB TUREK, CHIEF ROSEMOUNT FIRE DEPARTMENT
FROM: BERNIE SZCZESNIAK, FIRE MARSHAL
DATE: JUNE 26, 1987
SUBJ: FIRE ORDINANCES
Referring to Steve Jilk's 6/22/87 memo regarding the above subject:
ITEM I: I would recommend that the City of Rosemount adopt an ordinance
prohibiting the use of any cooking device, specifically on outdoor
decks for any residence exceeding a 41 -family occupancy or any
building in excess of a one story above grade (ground). This is
consistent with ordinances in place in several municipalities in the
Twin City metro area and with what is being considered in others.
ITEM II: Consistent with codes and ordinances in other municipalities
(Hopkins, Eden Prairie, St. Louis Park, Mankato, etc.), i recommend
that the City of Rosemount adopt an ordinance requiring automatic
sprinkler systems in all commercial occupancies and multi -
residential facilities over two stories in height, regardless of
type of construction. This would include all Industrial, Mercantile
and Assembly occupancies. It would also include any apartments,
condominium type structures, high-rise apartments, etc. The system
design would have to be to NEPA 13, 231 or 2310 as the occupancy
called for. In addition, the ordinance should address existing
occupancies with basement tenants. In this case the ordinance
should require -that all basement mercantile occupancies must be
equipped with a sprinkler system.
ITEM III: The current city codes give no enforcement authority for fire code
violations. I recommend that an ordinance be adopted giving
citation powers for fire code violations to the Fire Chief,
Assistant Chief and Fire Marshal.
ITEM IV: Consideration should be given to adopting a residential fire
sprinkler ordinance. As ,our community grows, the built-in fire
protection provided by sprinklers can help to reduce the need to
expand fire services. The construction of new fire houses or
staffing additional volunteers can be avoided, resulting in savings
to local government. Average cost for installation of a sprinkler
in a new home is
$ .95 per square foot. There are some tradeoffs. to
help offset costs. Examples include greater distance between
hydrants, narrower street widths and smaller water lines. Also,
reductions in building code requirements such as fire rated walls,
separation walls and density requirements may come into play. There
is precedent for such an ordinance. Salinas, California is
mandating sprinklers in new developments as is Greenburgh, New York.
Other municipalities include Scottsdale, 'AZ, Marueta, GA and North
Hollywood, CA. If the Council would consider such an ordinance, I
would be happy to assist in developing it.
You will no* that I have not developed specific wording for any of the above
items. If the ordinances as outlined above are considered by Council, I will
assist in providing the technical wording of the ordinance.
