What do I need to consider when adding a kitchen?

[Tyler Warlow]

Good morning everyone! My name is Tyler Warlow! I am trying to find a house that I can convert into a duplex so that I can rent out one side and live in the other. I realized that one of the things that I would need to do to many of the properties that have peaked my interest is convert a living space into a kitchen. Firstly, is this legal/possible to do? I've seen plenty of people add small kitchens for Air BnBs so I assume it is. Secondly, if it is possible, what must I be aware of to make sure this is done right. I want to ensure that I follow any sort of regulations and safety standards but I don't know where to even start or know how to estimate rough costs. Any advice?
