Newmarket mixes mature neighbourhoods around historic Main Street with newer communities like Woodland Hill and Summerhill. Older basements often need moisture and egress work designed in first, while newer builds finish quickly into theatres, gyms and suites.
With York Region rents climbing, a legal Newmarket basement suite is a serious income play. Whatever you start with, you end with finished square footage your family uses every week, and a number your Newmarket house carries at resale.
