Unincorporated Washington County, Colorado has adopted: No model building code (IBC/IRC/NEC) found published online — see the FAQ below for what governs instead; Manufactured/mobile homes: Colorado Division of Housing state standards apply, not a county-adopted code; County Zoning Resolution is in force but not published online — full scope on this point unconfirmed; HB22-1362 (2022, Colorado's statewide model energy/low-carbon code law) population-based carve-out analysis: unincorporated Washington County's population is approximately 3,060 (county total 4,817 per 2020 Census, minus Akron's 1,757 — Akron is the only incorporated municipality in the county per this corpus's counties.json), which is ABOVE the law's 2,500-resident exemption threshold, so the population carve-out alone would not exempt the county. HB22-1362's model-code mandate is triggered only when a jurisdiction adopts or updates a building code; within the bound of what this file could actually read online, no building code (energy or otherwise) was found to have been affirmatively adopted, so no adoption/update event was found for the law's mandate to attach to. Given the unpublished-Zoning-Resolution caveat above, this is stated as 'no trigger event found' rather than an affirmative certainty that none exists. Re-check if the County adopts any future code, or if the Zoning Resolution's actual text is obtained and found to reference one — either would trigger the law's Model Low Energy and Carbon Code requirement (binding on any update after July 1, 2026).. Local amendments apply — see the Unincorporated Washington County overview page for the full list.

A County-designated building inspector performs the inspection using checklist forms required by the State of Colorado Division of Housing, then the State issues an installation insignia sticker once inspections are satisfactorily completed. The same inspector also performs the foundation inspection if a Foundation Permit applies.
