Regulatory framework
The code baseline for Douglas County.
For unincorporated Douglas County, the official residential permit guide identifies the 2018 International Building Code, 2018 International Residential Code, 2018 International Fuel Gas Code, 2018 International Mechanical Code, 2018 International Plumbing Code, and 2017 National Electrical Code, with county amendments. The county building-code page says the department reviews applications, issues permits, and performs inspections only in unincorporated areas.
