Requests made before 3:30 p.m. on a business day are generally scheduled for the next business day. A two-hour estimated arrival window is available the morning of inspection, usually between 8:00 and 9:00 a.m.; real-time inspection results are available online.
Which codes and exemptions should I review?
For unincorporated Douglas County, the current adopted package effective July 1, 2026 includes the 2024 International Residential, Building, Plumbing, Mechanical, Fuel Gas, Energy Conservation, and Swimming Pool and Spa Codes with Douglas County amendments; the 2024 International Fire Code was adopted July 14, 2026. The current page also lists the 2023 National Electrical Code, the Colorado Model Electric Ready and Solar Ready Code, Douglas County Wildfire Resiliency Code, and rural fire-water standards. The NEC effective date is listed as January 1, 2027. Douglas County does not publish one compact general building-permit exemption list on its current Building Division pages. A basement finish permit is required when walls are constructed or electricity is added. Basic residential mechanical replacement/repair and certain basic roofing work may use e-permits, but that is an expedited permit path, not an exemption. Separate grading/erosion-control exemptions include decks, patio covers, stand-alone retaining walls, interior remodels, vertical additions that do not change the foundation footprint, demolition, landscaping, and swimming pools; these exemptions concern the DESC program and do not necessarily waive a building permit.
