Delaware HVAC Building Codes and Legislation
In Delaware, building code adoption and enforcement are primarily handled at the county and municipal levels.

Consequently, code requirements can vary between New Castle, Kent, and Sussex counties.
Regarding HVAC-specific standards, the state has historically adopted the following model codes at the state level, which serve as a baseline for local enforcement:
- International Mechanical Code (IMC): Generally based on the 2018 edition.
- International Fuel Gas Code (IFGC): Generally based on the 2018 edition.
- International Energy Conservation Code (IECC): The state, through the Department of Natural Resources and Environmental Control (DNREC), mandates energy conservation standards, with the 2018 IECC and ASHRAE 90.1-2016 currently serving as key benchmarks for energy efficiency in buildings.
