Is Arvada's ADU code compliant with state law?
✓ Verified against code · August 19, 2026
The state says no: Colorado's October 2025 compliance review listed Arvada as non-complying. The specific conflicts: ongoing owner-occupancy enforced by deed restriction, a blanket one-space parking mandate, and a 600 sq ft cap on small lots — inside the 500–750 sq ft range the statute protects. The August 2025 code amendment left all three in place. State law controls on paper, but expect the counter to apply the city's code; get positions in writing.

How current is this?
Arvada’s ADU rules run under Land Development Code §5-1-5-2 (2022 LDC (Ord 4793), amended by Ord 4905). Arvada's ADU framework dates to its 2022 code and was amended in August 2025 — after the state deadline — without fixing the provisions that appear to conflict with Colorado's ADU statute: ongoing owner-occupancy with a deed restriction, a blanket parking mandate, and size caps that dip below the statute's protected range. The state's October 2025 compliance review listed Arvada among the non-complying jurisdictions.
