Modifications
The pre-approved ADU design cannot be revised and must be permitted as designed. The ADU's may be oriented in any direction and floor plans may be mirrored (flipped). If you would like to make changes to the design, layout, floor plan, etc., you must submit for a separate permit detailing those changes. This application can be made simultaneously while applying for the pre-approved ADU permit but is not an expedited review. Not all proposed changes will be approved, so it is recommended you discuss the proposed changes with Permit Center staff prior to applying for either permit.
