RE: 1500 & 1526 Main St. - Storage Container Placement - W.O. #3597
-
I have reviewed the conditions relative to the placement of ,the storage containers on
these properties with regard to compliance with applicable code provisions for
separation from adjacent buildings and property lines. I have discussed these condi-
tions with Dave Puent, Building Official of Springfield, and he requested that I make
a code analysis and written statement with regard to my findings. Based on my
observation of the conditions and review of the applicable code requirements, I make
the following report and findings:
1. DescriPtion of Buildings: These are used ocean transport shipping contain-
ers of aluminum and/or steel construction which have been reconditioned and
fitted with additional doors to be used as storage space in conjunction
with the apartment dwelling occupancy on these properties. These storage
units are 8 ft. wide, 8 ft. high and 35 ft. long. They are set on a gravel
base or asphalt pavement on top of the ground surface. The containers are
placed so that the closest distance to the property line is at 1500 Main
Street where the distance to the west property line is 7 ft. The closest
distance to adjoining building is 12, ft. at the south and the closest
distance between containers is 6~ ft. Containers have access on all sides
to the doors.
2. Code Analysis: I have read the October 4, 1989 memorandum from the City of
Springfieid Development Services Department to you, which in Item #1(c)
indicates a minimum placement or separation from the property lines and
from adjacent structures. It appears that the placement is based on de-
termining that these storage units constitute a Group B-2 storage' oc-
cupancy. My review of the code criteria would result in a determination
that these storage units are a Group M-1 occupancy as a detached private
storage shed accessory structure to the Group R-1 multi-family dwelling
occupancy. The square footage of even two of these storage units combined
is less than the maximum 1,000 sq. ft. allowed for the Group M-1 occupancy
and the use is actually a private storage structure, which is similar to
other attached or detached private accessory structure to a residential
occupancy. As a Group M-I occupancy, the minimum distance to a property
line allowed in Table 5-A is 3 ft. The minimum distance from the storage
unit to a R-l occupancy with an assumed property line between the two would
I

I
be 8 ft. and the minimum distance between adjacent M-1 occupancy buildings
would be 6 ft. with an assumed property line between.
As further just ificat ion that the M-l occupancy can be related to other
than a single family residence occupancy, Table 5-B indicates the one-hour
occupancy separation between the M-l and any of the other occupancies and
H-l; therefore, an M-1 occupancy can be attached or accessory to any of
these other occupancies. I know of no code criteria that would limit the
M-l occupancy in any other way; therefore, I believe that the installation
of these storage containers is in accordance with the applicable code
requirements.
I hope you find this report adequate for your purposes at this time. Please contact
me if you have further questions. Thank you for this opportunity to be of service.
Very truly yours,
Emile Mortier, P.E.
