What model building code years does SolarAPP+ enforce?

To satisfy the greatest number of jurisdictions, SolarAPP+ was initially built to the 2017 National Fire Protection Association (NFPA) 70 National Electrical Code (NEC) and the 2018 I-Codes (International Residential Code, and International Building Code) developed by the International Code Council (ICC). SolarAPP+ now accommodates jurisdictions that utilize the 2020 NEC and 2021 I-Codes (as enforced in California 2022 Energy Code). As additional code updates are made (such as the 2023 NEC), these will also be incorporated as options for jurisdictions to select.

SolarAPP+ also complies with Title 24 of California Building Standards Code. Please visit the FAQs below for more details for information.
