Summary
Staff briefed commissioners on proposed Title 18 amendments to bring Lincoln into compliance with state ADU and JADU laws, covering definitions, size and setback limits, parking exemptions, review timelines and architectural standards. Commissioners provided feedback on size caps, design review, utilities and implementation pace.
The Planning Commission held a workshop to review proposed amendments to Title 18 intended to align Lincoln's zoning with recent state accessory dwelling unit (ADU) and junior ADU (JADU) laws.
Senior planner Efren Sanchez led the presentation describing ADU types (detached, attached, conversions), JADU limits (up to 500 square feet and owner-occupancy requirements), and a legislative timeline showing iterative state changes since 2016. Staff summarized proposed draft ordinance changes: updating terminology to ADU/JADU, adding JADUs as a permitted land use, clarifying zones where ADUs are allowed, reducing review timelines to 60 days, removing certain local barriers, setting objective architectural standards, specifying setbacks (four feet side/rear for detached ADUs), limiting detached ADU height (typically 16 feet; 18 feet near transit), and clarifying when impact fees apply (no impact fee under 750 square feet).
Commissioners asked detailed implementation questions about owner-occupancy, fire sprinkler triggers, sale or condominium conversion of ADUs (condominium/parceling process required), setbacks and maximum size rules (state-prescribed maximums: lesser of 50% of the primary dwelling or 1,200 square feet in many cases), parking exemptions, HOA interactions, and public-works implications related to utilities and capacity. Sanchez said objective standards and a menu approach to architectural materials were proposed to reduce discretionary review burdens.
No formal action was taken; staff will refine the draft ordinance and return with clarified sections identifying where the city exercises discretion versus minimum state-mandated standards. Commissioners emphasized the need to be explicit in reports about deviations and to coordinate with public works on utility planning for a potential surge of ADU applications.
