RE: Lot 7, Block 313 Capitol Hill Addition, Larimer County,
Colorado 3 Z '3 5--7&2EF- T
Gentlemen:
We have visually inspected the existing home at the above
referenced address. This inspection was performed on November 3,
1995. This inspection was performed in order to determine the
condition of the existing foundation system and the feasibility of
adding- a s-eoorrd floor- u-ader the existirrcT roof- and over t1re porch
area.
The home consists of a double wythe brick home founded on a
concrete block foundation. The original home, constructed circa
1910, consists of 728 square feet with a ten (10) foot deep rear
porch. The porch was subsequently enclosed, a basement was
excavated under the south half of the home, and an exterior stair
well was constructed.
It is our opinion that the foundation is currently sound, although
footing widths are unknown. The proposed construction is feasible.
However, several modifications to the existing framing will be
required.
First, the center beam will need to be reinforced. We recommend
the construction of a 8" x 12" footing with one (1) #4 continuous
on top of the slab each side of the stair opening and along the
entire bearing wall.
Secondly, new floor joists constructed of 2x10's at twelve (12)
inches on center will be required to support the existing 2x4
rafters and the new floor loads. (Where floor joist spans are less
than 10'-2", twenty-four (24) inches on center is acceptable.) As
part of this, 2x4's at twelve (12) inches on center vertical
(approximately 4'-9" from the exterior wall) will be installed to
support the rafters on the floor joists below.
Some new foundation walls will be required. They should be eight
(8) inches thick with two (2) #4's vertical, extending a minimum
of thirty (30) inches below grade. An 8" x 16" footing will
support the wall. As an alternative to the above, a twelve (12)

monolithic footing and foundation wall may be used. Reinforcing
remains the same. The short section of block foundation wall under
the south porch wall should either be abandoned or replaced as
necessary. Furthermore, all openings on the main floor which are
bearing above should be retrofitted with double 2x10 headers.
This inspection consisted of visual observation only, made solely
to determine the structural integrity of- the described building.
Neither the inspection nor the report is intended to cover
mechanical, electrical or architectural features of the building
inspected.
If you have any questions, please feel free to call.
