Regulatory framework
The code baseline for Conejos County.
Conejos County's official Building Resources page states that, effective July 1, 2023, the County adopted the 2018 IRC for residential construction, 2018 IBC for commercial construction, 2018 IMC, and 2018 IECC for residential and commercial construction; its design-standard list also identifies the 2018 IFC. The County materials reviewed do not identify a newer 2026 county building-code edition. Electrical, plumbing, and gas work requires separate Colorado state permits/inspections unless a local program applies.
