No permit shall be issued by the Building Inspection Department or shall be valid for the demolition or alteration of part or all of any building, structure, place, or district which has been designated as historic by the County Council, prior to its referral to the Commission. The Commission shall have 60 days to review and/or recommend modifications to the permit proposal. The purpose of such review will be to determine whether the changes set forth in the proposal permit application are compatible with the reasons for including the structure, building, or place on the Register. If at the end of 60 days the Commission has not approved or agreed upon modification of the proposal with the owner, the permit shall be issued if it complies with all other applicable laws and regulations.

This requirement shall apply whether or not the proposed change or alteration also requires a building or other permit, provided the requirements of this Section shall not apply to any historic property located within incorporated municipalities in Pierce County.
