Building and renovating in Newmarket
Newmarket’s older homes near historic Main Street often need updated wiring, plumbing and layouts, while the 1980s to 2000s homes in Stonehaven, Summerhill and Glenway are well suited to basement suites, kitchen remodels and backyard decks.
Newmarket requires every additional residential unit to be registered with the Town under By-law 2013-13, and each unit needs its own entrance, kitchen, bathroom and sleeping area. A building permit is also required. We design and build to those rules so the unit can be registered and rented legally.
