AGO 1990 NO. 9 >

1.  A registered architect or professional engineer must sign and stamp or seal each individual page containing a building construction drawing, or revision thereto, prepared or reviewed by him or her and submitted or permitted to be submitted in support of an application for a building permit, unless the activities are exempt from the requirement that drawings be signed and stamped or sealed by reason of RCW 18.08.410 or 18.43.130(1)-(7), (9). 2.  In the absence of one of the exemptions in RCW 18.08.410, a person who is not a registered professional architect or professional engineer violates RCW 18.08.310 by preparing a design or construction drawing for a building and submitting that design, or permitting that design or drawing to be submitted, in support of a building application. 3.   Under RCW 18.08.460(1) a local building official may accept a request for a building permit and issue the permit based on a design or construction drawing that does not bear the signature and stamp or seal of a registered architect or registered professional engineer, even if the activities are subject to the requirement that drawings be signed and stamped or sealed.
