questions about government rules on Landlord/tenant leases and property tax for rental property

I’m going to be renting out a room in a house that I own (and also live in) and wonder if anyone has experience with this and if they have any links to government websites that outline some rules.

Specifically, I have some question about whether you have to pay a higher property tax rate if you are renting out a ‘bedroom’ in your house. I know that there’s a higher property tax and capital gains tax if your entire house is rented out, but not sure about ‘roommate’ situation.

(of course I do know about paying income tax and 5% VAT on rental income)

Thanks in advance if anyone has some insight.
