In Practice
The significance of ministerial approval is that neighbors, planning commissioners, and design boards cannot block an ADU application on subjective grounds — such as architectural style or neighborhood character — as long as the project meets objective standards. An incomplete application pauses the approval clock, so submitting a complete application with all required plans and documentation is essential to triggering the mandatory review period. Other states with ADU reform legislation have adopted similar ministerial review requirements, making the approval process more predictable and time-bounded for homeowners.
