A clothes washer system and/or a single fixture system in compliance with all of the following is exempt from the construction permit specified in Section 18.104.22.168 and may be installed or altered without a construction permit:

12. An operation and maintenance manual shall be provided. Directions shall indicate the manual is to remain with the building throughout the life of the system and indicate that upon change of ownership or occupancy, the new owner or tenant shall be notified the structure contains a graywater system.
