RE: Project Address: 20129 81 Ave W
Project: Grigg ADU
A preliminary review was done with the conditional use materials provided and we have the following
comments.
1.A building permit will be required for the modifications to the existing structure, including, but
not limited to removal of a non-bearing wall, addition of kitchen exhaust, installation of fire rated
doors, installation of smoke and carbon monoxide alarms. This permit will also include the
change of status of the space to an accessory dwelling unit.
2.A recent state of Washington amendment to the 2012 IRC definition of Dwelling Unit requires
that all required smoke alarms in the accessory dwelling unit and the primary dwelling unit are
interconnected in such a manner that the actuation of one alarm will activate all alarms in both
the primary dwelling unit and the accessory dwelling unit. This is in lieu of the fire separation
requirements between the units (fire-rated walls and doors). If the option for fire-rated walls is
proposed, the construction drawings will need to include the approved listing and details for the
wall assembly.
3.All other applicable requirements of the building code will be verified under the building permit
review and inspections. See City handout P1 for a representative list of requirements.
