-IMPORTANT NOTICE-

Island County staff is in the process of updating all Development Information Bulletins. This page will be updated as soon as this process is completed.

Development Information Bulletins (DIBs) provide general information and answer commonly asked questions regarding permits, procedures, and regulations. Regulations are often written in a style difficult to comprehend, interpret, and apply to specific situations. DIBs are an attempt to translate the legalese of regulations into clear and common language. In the DIBs, excerpts from regulations are combined with plain-language explanations, rewording of complex passages, and some interpretation by staff. While the hope is that use of the DIBs will reduce expense and effort, reading the regulations in some cases may be required.

IMPORTANT NOTE - "Development Information Bulletins" (DIBs) are intended to assist the general public in understanding the effect of codes and regulations. DIBs are not complete statements of the laws and rules and should not be used as a substitute for them. If conflicts and questions arise, the code and regulations are the final authority. Because these regulations may be revised or amended at any time, consult Island County staff to be sure you understand all current requirements before beginning any work. It is the responsibility of the applicant to ensure that the project meets requirements of all current codes and regulations.
