Tips

  • Fences and retaining walls ≤4 feet do not require a City building permit in Delta, though fence height/construction rules under Municipal Code 15.04.060 and 17.04.240 still apply.

Office hours: Not published on the City's Building page or any retrieved City document this session; inspection requests are called in from 8:00 a.m. to 4:30 p.m. at 970-874-7909, per the City's Inspection Guidelines (updated 6-12-2023).

Delta, Colorado has adopted: 2018 International Building Code (IBC) — per the City of Delta Building Department page (https://www.cityofdelta.net/cd/page/building); 2018 International Existing Building Code (IEBC); 2018 International Residential Code (IRC); 2018 International Fire Code (IFC); 2018 International Mechanical Code (IMC); 2018 International Plumbing Code (IPC) — adopted per the City's own Building page, but plumbing permitting/inspection itself is performed by the State of Colorado, not the City (see localAmendments); 2018 International Fuel Gas Code (IFGC); 2012 International Energy Conservation Code (IECC); 2023 National Electrical Code (NEC) — electrical permitting IS performed by the City of Delta (unlike several peer home-rule cities in this corpus, e.g. Montrose, where the State Electrical Board handles it); NOTE — code-edition discrepancy found and not silently reconciled: the City's own 2026 Schedule of Fees and Charges (Table 3A, Building Permit Fees valuation table) is explicitly headed 'Group (2024 International Building Code)', a newer edition than the 2018 IBC named on the Building Department page itself. Both are official City-published documents retrieved directly this session; the discrepancy is surfaced here rather than guessed at — confirm the currently-enforced IBC edition directly with the Building Department (970-874-7909) before relying on either figure for design compliance.. Local amendments apply — see the Delta overview page for the full list.
