Summary

Reduces regulatory barriers for the construction of Accessory Dwelling Units (ADUs).
By July 1, 2024, requires fully planning cities to ensure local development regulations allow for the construction of accessory dwelling units (ADUs) within urban growth areas (UGAs) that allow for single-family homes and comply with policies to:

permit ADUs in structures detached from the principal unit.
allow at least two ADUS on any lot size that allows for single-family homes;
Not impose setback regulations, yard coverage limits, tree retention mandates, and other restrictions for design review for ADUs that are more restrictive than those for principal units.
limit impact fees for ADUs;
not establish certain bulk regulations for ADUs;
not require owners to reside in lots with ADUs;
And not require public street improvements as a condition of permitting ADU.

Creates exceptions for lots with critical areas and their buffers and for watersheds.
An accessory dwelling unit (ADU) is a residential living unit providing independent living facilities and permanent provisions for sleeping, cooking, sanitation, and living on the same lot as a single-family home, duplex, triplex, townhome, or other housing unit.
