How current is this?
Longmont’s ADU rules run under LMC 15.02.080.E (Longmont Municipal Code) (Ordinance O-2025-35 (amended by O-2025-83)). Longmont adopted its state-compliance rewrite in June 2025 and amended it again in December. Its distinctive features: proof of City of Longmont residency at application (a broader reading than the statute's resides-on-the-parcel check), a total ban on short-term-renting ADUs, and a flat prohibition in the 100-year floodplain. We verified this answer against primary sources on August 19, 2026, and every change we catch is logged in the changelog.
