Bill > SB532

This bill revises county zoning regulations to mandate that counties allow at least one accessory dwelling unit (ADU) by right on lots with a single-family dwelling. An ADU is defined as a self-contained living unit with its own cooking, sleeping, and sanitation facilities, which can be attached, detached, or internal to the main dwelling. The bill prohibits counties from imposing numerous restrictive regulations on ADUs, such as requiring additional parking, matching exterior design, owner occupancy, or assessing impact fees. Counties can charge a one-time application fee of up to $250 per ADU and may continue to enforce building codes, fire codes, and public health regulations. The bill specifies that "by right" means approval without a public hearing or discretionary zoning actions, and it provides an expedited 15-day sanitation review process for ADUs on parcels with existing public water and wastewater service. The provisions are set to terminate on September 30, 2029, and are intended to increase housing flexibility and affordability by making it easier for homeowners to add secondary dwelling units to their properties.
