Additional codes: 2018 International Mechanical Code (IMC), 2018 International Plumbing Code (IPC), 2018 International Fire Code (IFC), 2018 International Energy Conservation Code (IECC) with Alaska amendments (Climate Zone 7), and NFPA 70 (National Electrical Code) as adopted by the Alaska Electrical Code.

- Owner-builder
- Homeowners may pull building permits for their own primary residence as owner-builders. The homeowner must occupy or intend to occupy the structure. For electrical and plumbing work, Alaska state law generally requires licensed contractors unless the homeowner qualifies for an exemption. Owner-builders assume all liability for code compliance.
- Contractor requirements
- Alaska requires construction contractors to register with the Alaska Department of Labor and Workforce Development (DLWD). Registration requires proof of general liability insurance and workers' compensation coverage. Specialty trades (electrical, plumbing, mechanical) have separate journeyman/master certification requirements.
