We’ve just started and have had a good experience so far.
We’ve really been fortunate to find a home that has the space that allows us to rent out our extra space and is new construction, to boot.
I get what you’re saying regarding calling it at an “apartment” versus an “in-law” suite and part of it is my concern that advertising it as an “apartment” might get me in trouble with the zoning folks. My “in-law” suite is part of our house and covered by our Certificate of Occupancy. If I were to rent the downstairs as an “apartment” I’d have to arrange for a full inspection and possibly have to install a full stove (I have a kitchenette right now). That’s the reason for now we’re pushing it as a private in-law suite with its own entrance. I’m certainly open to tweaking the text as we get more visitors and their feedback.
