Is building permit required if I plan to add a bathroom in a basement of a condominium townhouse?

Of course it will come with a small kitchen and new drywall over the entire basement.

Yes it is since your adding new drains.

Is this going to be a basement rental unit?

Any time you alter your home structurally or move or add drainage it requires a permit, failure to comply will make your home insurance null and void if you have problems down the road.

the first two posts are correct.

If you are adding drainage you will need it.

Good luck with your project.

Hi Brian, Mark & James.

Thanks for your replies, I noticed that you all specifically mentioned permit is required due to

new drains that is required.

Are you refering to the new kitchen drainage & Toilet lines?

Or are you guys refering to the new drainage outlet out of the basement? ( I have this at my basement do I still need to ask for a building permit)

You need a permit, period. Your adding living space, changing electrical, plumbing etc. Also adding a kitchen makes it a basement apartment. Which adds a lot more requirements to the permit, like egress windows, fire stops, etc.
