I have a plan to install an additional ductless air conditioning unit at commercial plaza. Main HVAC system is on the roof top. I am wondering whether I need to get a building permit for installation or not.

Hi Harry,

You are going to need electrical to both of the units so you may need that permit. If it is going on the roof, there is no structural work needed, it just sits on a raised pad of some type. If you are hanging it off the side of the building on brackets, you might need a permit.

Your HVAC guys should know these answers.

Good luck with it!

Since it is a new installation you will need a permit, at least an electrical one for the new circuit. Just give Oakvilles building department a call and they can tell you for sure. Obviously your HVAC installer should know also, but you can call the city to double check.
