More than anywhere nearby: the Basic Development Review flat fee alone is $6,925, and the city's own guidance puts typical total fees — review, impact, utilities — at $20,000–25,000 before construction. Budget for it up front.

How current is this?
Fort Collins’s ADU rules run under Land Use Code §3.1.8 and zone-district standards (Ordinance 009-2025). After the 2022–23 land-use-code repeal saga, Fort Collins re-adopted its code in May 2024 and rewrote the ADU rules for state compliance effective February 14, 2025 (Ordinance 009-2025). The rules are clean and generous; the fees are the story — expect $20,000–25,000 all-in before construction. We verified this answer against primary sources on August 19, 2026, and every change we catch is logged in the changelog.
