RE: Plan Check # 2007-1021
Project: Detached Garage
Project Address: 23811 77th Place W
During re -review of the above noted application, it was found that the following information,
corrections, or clarifications are needed. Please redline plans or submit two (2) sets of revised
plans/documents (affected sheets only) with a written response to each of the items below to a
Permit Coordinator.
1) ok
2) 3/12/08 Orikinal site plan showed the house and earake 5' apart Now it shows 3. This
changes the requirements For the house now you can only have maximum 12"eaves and
they must be protected with a listed tested l HR Assembly (see attached sample). To do this
the eave must be soffrtted and protected. Provide detail of proposed eave protection with eave
dimensions. This will also block some of the ventinie so also provide attic ventilation
calculations. Additional vents may be required. Because the work is done on a separate
buildink then_a separate building permit would be required. Contact a permit coordinator for
application requirements. 2/21/08 need 1 -hr listed and tested assembly on the plans. See
attached samples. Based on R302 because the house and garage are not 6' apart, the garage wall
will need to be one-hour fire -resistive rating with exposure from both sides and no openings are
permitted in this wall with maximum of 4" eaves. See attached 1 -hr listed and tested assembly.
Note on plans.
3) 3/12/08 This still does not -appear to be addressed. Please provide written response. 2121108
New Based on the picture in the file it appears that the foundation for a 2 car garage was
poured. Please specify if this is to be altered or if it will be completely removed and a new
foundation will be poured. Because we were not present to inspect before the concrete was
poured, if the existing is to be altered, special inspection by a Washington State Licensed
Engineer will be required to verify the structural integrity of the foundation. Also based on the
pictures it does not appear to have all the required holdowns, so retro -fit holdowns will be
required and special inspection is required for epoxy or expansion anchor holdowns.
