Full Breakdown
Moorpark Municipal Code § 17.28.020(G) makes ADU approval a ministerial zoning-clearance process rather than a discretionary permit: applicants must comply with California Government Code Sections 65852.150 through 65852.26 as well as the applicable development standards spelled out elsewhere in Title 17, such as setbacks, height, and parking. Because the process is ministerial, the community development department cannot hold a hearing or exercise discretionary judgment on a conforming application - it either meets the standards and gets cleared, or it doesn't.
Violations & Fines
Building an ADU without first obtaining zoning clearance, or one that doesn't meet the state ADU statute or the city's Title 17 development standards, is a code violation subject to enforcement.
