Can I install mechanical equipment, duct work, or exhaust fans myself?

Mechanical permits are required when vents and ducts are added, replaced, or relocated. This includes dryer vents, exhaust fans, range hood vents and extending heating ducts, adding registers, replacing furnaces and air conditioning units. A building owner can self-perform this work however they will still be required to pull a permit and pass all the necessary inspections. We strongly recommend you hire a professional as they will be familiar with the code requirements as well as how to identify and protect penetrations through rated assemblies in accordance with the code.
