It is unlawful for any person to erect, construct, enlarge, alter, repair, move, improve, or convert any structure regulated by this Title, except as provided for in this Title, or cause the same to be done without first obtaining a separate permit for each structure from the City Administrator as required by this Title.

Exemption from the permit requirements of this Title does not authorize any person to do work in any manner in violation of the provisions of this Title or any other rules or regulations of the City, the State of Oregon, or the Federal government.

Unless otherwise exempted, separate plumbing, electrical and mechanical permits are required for any such work performed for floating structures regulated under this Title.

Exception:  A one-time addition of not more than five percent in area or eight inches in width or length, whichever is less, to the area of an existing deck, walk, porch or the float for a floating home or combo-structure is allowed without permit provided such extension does not cause an unbalanced or overloaded condition and provided such extension does not reduce the separation between floating structures below what is allowed by this Title. Any such additions need to meet the requirements of Title 33 of this Code.
