Council members press staff on ADU rules and potential state mandates

During the study session council members sought clarity on accessory dwelling units (ADUs) and whether state legislation could override local rules. A committee member asked whether ADUs are controlled under the land code; staff answered that "ADUs would be controlled either in a standardized zoning district or PD zoning district," and that, at present, the city does not have standards or regulations for ADUs across standardized districts.

Council members discussed whether recent state legislative changes could force ADU allowances in local jurisdictions. One participant said courts will likely decide some conflicts: "Actually, this is all gonna be decided by these lawsuits," and other members noted that only certain communities designated as transportation‑oriented communities are currently subject to the state mandate. Staff and members emphasized that Castle Pines is not presently designated as a transportation‑oriented community and therefore is not within that mandated group.

Members asked whether the city could adopt uniform ADU standards or amend PDs to allow ADUs more broadly; staff explained that PD amendments require negotiation with landowners and that standardized rezoning is another path but would require a formal process. No policy decision was taken in the meeting; the conversation was exploratory and staff indicated follow‑up would be possible.
