A second self-contained space changes what a house can do. It houses a parent without putting them in a bedroom down the hall, or it carries part of the mortgage, and in Durham it is one of the hardest things to search for — the big portals have no filter for it.

How we picked these: These are homes whose listing describes a separate entrance, in-law suite or basement apartment. That wording comes from the listing brokerage and is not a statement about whether the space is a legal second unit. Retrofit status, fire separation and zoning all have to be confirmed with the municipality before you count on rental income — ask us and we'll check before you write an offer.
