The plan review was performed under the 2005 Oregon Residential Specialty Code. The review
of the submitted plans will be completed when the following information is provided.
1. The first level doesn't show the required smoke detector in the heated space required
by R313.1 #3. Revise and submit two copies of sheets A2 -2, A -4, A -5, and A -6 to
show this smoke detector.
2. This first level has heated space on slab. Provide two copies of the details showing
how slab edge insulation will be provided here, Per N1104.1 (1).
3. The master bedroom doesn't show the required smoke detector required by R313.1
#1. Revise and submit two copies of sheets A2 -3, A -4, A -5, and A -6 to show this
smoke detector.
4. The master bathroom tub area doesn't show the bath fan required by R303.3.1.
5. Provide a detail of how the second floor bath fan will vent to the exterior without
compromising the structural integrity of the third floor beams, or vent through the
roof ceiling in the four feet in which penetrations are restricted.
6. Sheet A2 -1 specifies modified 2 hour dwelling unit separation. Detail 3/S -12, note
#2 and 4/S -13, note #2 specify the contractor can substitute fire rated plywood for
one layer of the 5/8" type "x" gypsum at shearwalls. This does not meet the
modified two hour assembly from Appendix O. Provide two copies of sheet S -6 with
this note deleted, or provide listing information to show which listed assembly this
note meets the criteria for.
7. The connection of the drag truss to both walls should be designed. Provide two

requirements of membrane penetrations in a modified two hour wall in accordance
with AO103.7.3.6 and R317.3.

and call for Path 8. Please provide two copies of a revised sheet A -7.
10. Detail 13/S -6 specifies a "4' rated roof assembly with no penetrations." This does

plywood, or the fire resistive plywood being used at the cricket and the roof covering
under, within 4' of the property line.
11. Show how the rated crickets will vent to the exterior per R806.1 and R806.2.
