Does Aurora's lawsuit against the state cover ADUs?
✓ Verified against code · August 19, 2026
No — Aurora joined five other home-rule cities suing over different housing laws (occupancy limits, transit-oriented density, parking) and an executive order. The city is 'not currently fighting' the ADU law in court; it just hasn't complied with it.

How current is this?
Aurora’s ADU rules run under UDO §146-3.3.6.G (2018-era rules carried into the 2019 UDO) (No HB24-1152 compliance ordinance exists). Aurora is the state's highest-profile ADU holdout: its council voted a staff-drafted compliance ordinance down in June 2025, the state formally identified Aurora as non-compliant with the ADU law in October 2025, and as of August 2026 the codified rules are still the restrictive 2018 regime. Where the code conflicts with C.R.S. 29-35-403, state law controls on paper — but the city's counter still applies its own code, and only 9 ADUs have been permitted since 2018. We verified this answer against primary sources on August 19, 2026, and every change we catch is logged in the changelog.
