More Information
Q: What is an ADU?
A: An ADU is a secondary home located on the same property as a primary residence. It can be attached to the main home or detached from the main home.
|
Q: What is a pre-approved ADU plan?
A: These basic plans are pre-approved by jurisdictions in Kitsap County and can be used for faster permitting. The availability of these plans will support affordable housing efforts by making it easier and less expensive for community members to build ADUs on their property.
|
Q: Where will I be able to use these ADU plans?
A: The pre-approved ADU plans will be available for use in urban areas of unincorporated Kitsap County and anywhere in the cities of Bremerton, Bainbridge Island, Port Orchard, or Poulsbo for free, as long as no modifications to the plan are made. The plans are available for use in the rural areas of unincorporated Kitsap County, for a fee.
|
Q: Can I get a more detailed look at the plans and options?
A: Yes. To request a detailed pre-approved ADU planset, you can complete a request form. A copy of the detailed plans will be emailed to you. The plans will be provided with a watermark indicating they are "not for construction". These plans can be used to review design options (such as roof configurations and optional porches, if available for the selected model) and to estimate construction costs before applying for a permit.
|
Q: Can I modify the plans?
A: The plan sets have built-in flexibility that allows you to choose specific colors, styles, and materials. You can make the following non-structural choices:* If it is an egress window, sill heights must be maintained, and window operation must meet the requirements of IRC2021 and Washington State Amendments.
