Dear Ms. Hanson
The following items were noted during our inspection of the moved house on your
property. These items must be inspected and approved before the home can be occupied.
1. One egress window that meets the following requirements shall be installed in
each sleeping room. The window must have an openable area of 5.7 sq. feet, a
maximum sill height of 44 inches, the openable height of the window shall be a
minimum of 24 inches and the openable width of the window must be 20 inches
minimum.
2. Smoke detectors shall be installed in each sleeping room and on each level of the
house.
3. The masonry chimney must be removed and replaced with a chimney large
enough to vent the heating appliances.
4. All gas piping, water piping and drainage piping must be pressure tested and
inspected.
5 Remove plaster from walls in second floor bedroom where large cracks appeared
after the move. Remove the plaster from the ceiling joists in the main floor living
room that is sagging and cracked. Along with the engineer, we would like to
inspect the framing in these areas.
6. Insulate attic area to R-38 minimum. Fill all exposed wall cavities with
insulation. Insulate floor joists to R-30 minimum.
7. Install a guardrail around the open stairwell on the second floor. This rail to be 36
inches in height minimum with pickets spacing of no more than 4 inches between
each picket. Install a handrail on one side of the stairwell that is 34" to 38" above
the nosing of the treads, and return the ends of the handrail into a wall or post.
8 Ventilate the new crawl space at the rate of one square foot of ventilation per
every 300 square feet of floor area.
9. The new footings should be approximately 8" x 16" with an 8" foundation wall
placed on top of the footing. Provide a crawl space access of 18" x 24" and 18"
of clearances from the ground to the floor joists. Wood beams or girders must be
located at least 12" above the ground in the crawl space. A vapor barrier is also

required on the ground in the crawl space. Maintain all existing interior bearing
points. (see copy of Nicholls Engineering report.)
10. Support the front porch overhang at all existing bearing points.
11. All new mechanical equipment, gas piping, and plumbing piping shall be installed
to current code requirements.
12. A final structural engineer's report will be required prior to occupancy. This
report shall address the concerns noted in the enclosed engineers letter and certify
the over all structural integrity of the house. Any corrective measures that are
required by the structural engineer, need to be inspected by this department.
13. The exterior of the home needs to be repaired and made weather tight.
14. Prior to commencement of any work on this home, permits will be required for
the foundation system, structural repairs, mechanical equipment, and new
plumbing and plumbing fixtures. All electrical work is permitted and inspected
by the Department of Labor and Industries.
If you have any question on the above items, please feel free to call me at 477-7130.
Sincerely;

Re: Inspection of Transported House
Dear Mr. Stelzer,
Per your request, our firm conducted a visual inspection of the home you were
transporting at Liberty Lake, WA. The following is a report of what we observed
and our recommendations.
INSPECTION
It should be noted that our inspection was quite limited. The ground floor structure
was visible and we were able to inspect the joists and verify the existing
configuration. The remainder of the house, however, was limited to a visual
inspection of the finished walls, ceiling, floor, and roof. The actual framed
structure was not at our disposal. We took measurements of the overall house, the
location of the bearing walls, and the location of the beam line supporting the
ground floor joists. We crawled under the house to inspect and verify the floor
structure. We inspected the remainder of the house by walking around and through
the house looking for obvious signs of damage.
RESULTS
Most of the ground floor joists had been replaced with new 2x10's at 16" o.c.
Through the attached calculations, we feel this floor structure is adequate. We did
observe the lack of beams supporting the floor joists and the bearing wall line. In
addition, we noted that a post line supporting the beams should be determined.
The remainder of the house appeared to be in structurally adequate condition based
on our limited access to structural elements. We had very limited viewing of the
roof system and no comment can be made, either positive or negative, about the
roof structure or the chimney. We noted some minor cracking in the plaster walls.
We are not able to determine if these cracks were pre-existing to the move, were
caused by normal stresses during the move, or caused by the accident. Extensive
cracking was noted on the chimney and on the exterior wall in the top floor room
adjacent to the stairwell.
P.O. Box 14706 • Spokane, WA 99214-0706 • (509) 921-6747
RECOMMENDATIONS
We recommend the chimney structure be removed. Since we did not have access
to the internal structure of any of the walls, we recommend the structure of the
exterior wall in the 2nd floor room adjacent to the stairs be inspected by a registered
structural engineer once the plaster is removed. In addition, the following beams
and posts should be used to support the ground floor system.

Refer to the Floor -Framing Plan shown on page 1 of the attached calculations for
further clarification. The beams and posts have been designed for the supports as
shown in the Floor -Framing Plan. If a different support system is used, the beams
and posts should be revised.
If you have any questions or comments, please do not hesitate to contact our office.
