Re: 807 Oregon St.
Dear Mr. Mazza & Mr. Magritz;
The inspection conducted on Tuesday, October 21,2003 revealed several code issues that must be
addressed. Additionally it became evident there is some confusion over what improvements and
conditions will apply for the use of various areas for RC Vehicle Racing. I hope to clarify code
requirements with this letter.
Enclosed with this letter is a copy of the August 5, 2003 correspondence I sent to you regarding the
conditions of use. Per this letter you will find that the RC Vehicle Racing will be allowed in the various
areas as long as the total combined capacity for the 3 rooms in which racing will be conducted does not
exceed 50 persons. After the inspection conducted this past Tuesday, I leamedthat the second floor, ....
east room only has one exit. As a result, this area will be limited to a maximum of25 occupants, asthis
was the code limitation under the previous building code. Since each of the remaining two rooms used
for racing has access to two exits, those rooms may be occupied by up to 50 occupants each. Again,
keep in mind that at no time may the combined occupancy for these 3 rooms exceed 50 occupants. As
stated in the previous correspondence, each ofthese three rooms must be posted with a capacity sign.
\Ve will need to discuss verbiage of these signs in the future so as to address the room capacity as well as
the total combined capacity.
Referencing the August 5th correspondence, please remember that you must obtain specific approval to
exceed the 50-occupant limit for each event. To date no submittal has been made indicating when these
events may take place, nor has any submittal been made to outline what additional life and fire safety
measures will be provided to allow a greater occupancy. Confirming point 3 made in the July 16, 2003
-correspondence (enclosed) submitted on your behalf by Norman Krause, CR Meyer, I do not anticipate
approving any temporary approvals that would exceed 100 occupants as this would not have been
allowed by the previous Building Code.
During this recent inspection it was learned you have already been using this building for RC Vehicle
Racing. Please be advised this must cease until you have secured the required Occupancy Permit. This
will not be approved until all life and fire safety code issues have been satisfied.
The Building and HV AC code issues noted during the October 21, 2003 inspection are as follows:
1. Your present building permit does not cover all of the work witnessed. A review of this permit
shows it is for the 3 restrooms, furring and finishing the exterior walls ofthe second floor and
installing a suspended ceiling in the second floor. This permit did not include replacing windows on
the second floor, installing a room in the west, second floor room or installation of any other various
partition walls in this building. A floor plan must be submitted showing the alterations that have
I taken plus any other alterations that are planned to obtain a permit for this additional work.
2. The emergency lighting and exit lighting shall be brought into compliance with the present day code
standards as previously stated in my August 5, 2003 correspondence. Because the previous lighting
was removed and/or altered, it must be reinstalled in compliance with present day code standards. It
is suggested that you obtain professional design services to assist you with this as the present day
code is more involved than past code standards.
3. The first floor, west room used for racing must be provided with an HV AC system that meets present
day standards. This area was previously used for warehousing. Warehousing did not have
requirements for fresh air exchange. Due to the conversion to an occupied space, this area must now
be provided with an HV AC system that will provide for the required amount of fresh air and
exhausted air based on the calculated occupant load as well as meeting the heating needs of this
room. HV AC Plans prepared by a Wisconsin Registered HV AC Designer, Architect or Engineer
must be submitted for review and approval.
4. The exit path leading to the west, second floor fire escape must be at least 44 inches in width. This
may be reduced to 36 inches ifthe occupant load will not exceed 50 occupants. (If you are planning
events to exceed 50 occupants, the 44-inch exit path will be required.)
5. All stairs leading to participant platforms shall be provided with uniform stairs. Treads shall be a
minimum of 11 ", risers shall not exceed 7", and the risers cannot be open. See Comm 62.1003.3.3,
copy provided.
6. Guardrails shall be provided as required in COMM 62.1003.2.12. Refers to participant platforms and
the loading dock platform. Copy provided.
7. Handrails shall be provided as required in COMM 61.1003.3.3.11. Refers to the participant platform
stairs, loading dock ramp as well as any existing stairs that do not have handrails. Copy provided.
"8. . The second floor west bathroom shall have a'door where'the hinges are located at the comer of the
rooni. The doorknob/latch must located toward the tenter ofthe wall for handicap accessibility
purposes~ The door may swing into the restrooin due'to the size of the restroom.
9. The door for the first floor restroom shall not swing into or obstruct the exit passageway. This door
can swing into the restroom due to the size ofthe restroom.
10. Eliminate the trip hazard for the SW comer person platform in the 1 st floor racing room.
11. Grab bars shall be provided on the side and rear walls of the restrooms.
12. Toilet Flush levers shall face the open area of the room, they cannot be on the side ofthe tank
adjacent to a wall.
13. The bathroom sink traps and water line valves shall be protected with insulating material to prevent
bums and abrasions.
14. Obtain Occupancy Approval prior to use of the Racing Rooms.
This list was provided in an attempt to assist you with this remodel. It may not be an all-inclusive list.
For this reason you were previously encouraged to seek the services of a design professional. It may still
be beneficial for you to consider seeking these services to lessen the likelihood of being presented with
unexpected code issues during this project.
If you have any questions, please call me at 236-5045.

Re: Hobbytown Relocation; 807 Oregon St.
Dear Norm,
My apologies for not being able to respond sooner. I received your correspondence on July 25, 2003 and
find it to be a fair account of the results of the conference call. I wanted to take this opportunity to
elaborate further on what I understood to be resolved from the conference call we had with Randy
Baldwin, IS Bureau Director, State of Wisconsin Department of Commerce, Division of Safety &
Buildings.
1. The su~ject building at 807 Oregon St., will be allowed to use the previously defined areas. for RC',
vehicle racing if the total capacity does not exceed 50 persons. As you state,.this occupant load must '
be posted (at the main entrance.) This use will be allowed as the Department has rendered direction
that assembly uses not exceeding 50 persons may be considered a type Buses.
This is further supported by the Department's "General Guidance Tool for Evaluating changes of
Use in Commercial Buildings. " In this report, under Consideration 3, since the proposed RC Racing
can be considered an accessory use to the proposed principle Retail use; the RC Racing would not be
considered a Change of Occupancy. As a result these combined uses only need to be reviewed for
compliance with the previous code. Ifthis review were to show that this structure did not comply
with the previous code for the RC Racing use, then any modifications would have to be done in
compliance with the current code.
Norm, please note, that in item 1 you indicate "as it currently stands, does require any physical
changes..." I suspect this was mis-typed and should have read "does not require any..."
2. If the owner has the need to exceed the 50 occupant limit for special events, it is within this office's
discretion to review this as a Temporary Use per COMM 61.03(11). This section allows code
officials the authority to grant temporary use approval, but also gives the code official the authority
to require additional safety measures.
Per our discussion after the conference call, it was stated that the owner of Hobbytown was leaning
toward the installation of a smoke detection system. A system that complies with NFP A 72 would
be a system that would be viewed favorably as it would provide early warning to the occupants.
However, this is not to say this would be the only requirement if a request is made for a Temporary
Use. Additional input on this would be requested from the Fire Department.
Since various areas are undergoing significant remodeling, I would suggest that Mr. Magritz continue
consulting with you or another design professional to determine if the building was in compliance. One
area of concern I would have would be emergency lighting. I do not know what exists now, but with a
building of this size, the previous code would have required emergency lighting. If this lighting was
removed in preparation for the remodeling, then it would have to be reinstalled to meet present day
standards. This isjust one example of why this building should be reviewed with a design professional,
to identify these types of issues early on and avoid delays later in the project.
If you have any questions, please call me at 236-5045.
Sincerely;
Allyn Dannhoff

Dear Bill:
This letter is intended to confirm the outcome of a conference call held at 9 a.m.
among myself, Ken Kraase, Allyn Dannhoff (City of Oshkosh Building Inspector),
Randy Baldwin (State of Wisconsin) on June 26,2003.
1. Your building, as it currently stands, does require any physical
changes or alterations to he used as is up to a maximum capacity of
50 people. The capacity will need to be posted.
2. In the event that the 50 person capacity is exceeded (up to a maximum
of 100) a conditional use permit would be required by the City of
Oshkosh Building Inspector and approved by the Fire Chief. Hobby
Town would need to apply for this Conditional Use Permit outlining:
. Proposed use.
. Quantity of people.
. Life Safety measures proposed.
. Diagramatic plan showing fixture and location of possible people
and in what concentrations. .
After review, a determination would be made regarding acceptance or
other needed considerations.
3. In the eventthat you exceed 100 people, a Conditional Use Permit
may no longer be acceptable and considerable changes may be
required; for example, elevator, fire protection. exit widths. etc.
