-IMPORTANT NOTICE-

Island County staff is in the process of updating all Development Information Bulletins (DIBs). As each DIB is updated, the name of the DIB will appear in green and will link to the updated information.

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.
