Detached Accessory Dwelling Units - For a main residence and any detached ADUs, a separate permit application is required. A single plan set depicting all structures may be submitted with the understanding that all the permits must be issued concurrently.
Cottage Unit developments - A separate permit application with plans and other submittal documents specific to each dwelling unit is required. Each site plan needs to indicate the fire separation distances to imaginary lot lines between the residences to determine if any fire-rated assemblies are required. The overall site plan will be contained in the Enhanced LSM and does not need to be submitted as part of the building permit set.
