Staff proposes ADU code changes: one ADU per lot, 50% size limit and owner-occupancy requirement

City staff recommended clarifying accessory dwelling unit rules in the Unified Development Code: consolidate repeated standards, require one off-street parking space per ADU, limit ADUs to 50% of principal dwelling size for detached units, require owner-occupancy and HOA written consent where applicable, and add an administrative variance option; council discussed numeric height limits and possible grandfathering.
