Do I need parking for a Castle Rock ADU?
✓ Verified against code · August 20, 2026
This is genuinely unresolved and we would rather say so than guess. The ADU chapter itself contains no parking requirement. But that same chapter says all district zoning regulations apply to ADUs, and the town's general parking chapter requires two spaces per dwelling unit with no ADU exemption we could find. Whether the general standard reaches an ADU is a question for the town's planning staff before you rely on either answer.

How current is this?
Castle Rock’s ADU rules run under CRMC Ch. 17.61 (Accessory Dwelling Units) (Ordinance 2025-023). Castle Rock is bound by HB24-1152 through DRCOG. Ordinance 2025-023 took effect July 1, 2025, one day after the statute's June 30 deadline — a timing note rather than evidence of anything, since the deadline governed filing rather than the effective date of local code. That ordinance made a real change: the original 2017 ADU ordinance imposed a genuinely ongoing occupancy obligation, and the current code checks residency only once, when you apply. We verified this answer against primary sources on August 20, 2026, and every change we catch is logged in the changelog.
