L-102.3 Local rules
Renovating in Newmarket: what to know
Neighbourhoods and homes
We work across Newmarket, from the older homes around Main Street and the historic downtown to established neighbourhoods such as Glenway, Stonehaven-Wyndham, Summerhill Estates and Woodland Hill, and the newer subdivisions on the town’s edges. Plenty of Newmarket homes still have the basement, bathrooms and kitchen they were built with, and that’s usually where a renovation starts.
Permits
- Finishing a basement needs a building permit in Newmarket. So do additions, removing or adding walls, structural changes, new or enlarged window and door openings, plumbing and HVAC alterations, a below-grade entrance or walkout, and creating an additional residential unit. Floor and ceiling finishes, painting and same-size window replacements generally do not. Source: Town of Newmarket: Building and Renovating
- Applications go through the town’s online Development Portal. Once an application is complete, the town says it needs about 10 to 15 working days to review it and say whether the permit will be issued. Fees are on the town’s fees and charges page.
- Decks: a deck attached to the house needs a permit. A freestanding deck needs one if it is larger than 10 m² (about 108 sq ft) or, per the town’s permit list, more than 600 mm above grade. Zoning setbacks apply either way.
- Basement apartments (additional residential units): allowed, with building permits and inspections, and every unit must be registered with the town. Source: Town of Newmarket: Additional Residential Units
- Heritage district: in the Lower Main Street South Heritage Conservation District, alterations to a property need a heritage permit, in addition to any building permit. Source: Town of Newmarket: Heritage Conservation

DDR Contracting Ltd is based next door in Aurora and renovates homes across Newmarket: kitchens, bathrooms, basements, additions, decks and whole-home renovations. Call or text 647-991-8551 to talk about your project. ### Do I need a building permit to finish a basement in Newmarket? Yes. The Town of Newmarket lists finishing a basement as work that needs a building permit. A permit is also needed for a below-grade entrance or walkout, new plumbing, and for turning the basement into an additional residential unit. ### How do I apply for a building permit in Newmarket? Apply through the Town of Newmarket's online Development Portal with your drawings, forms and fees. Once the application is complete, the town says it needs about 10 to 15 working days to review it and decide whether the permit can be issued. ### Does a deck in Newmarket need a permit? A deck attached to the house needs a building permit in Newmarket. A freestanding deck needs one if it is larger than 10 square metres (about 108 square feet). Either way, the deck has to meet the zoning setbacks for your lot. ### Can I add a basement apartment in Newmarket? Yes. Newmarket allows additional residential units, such as basement apartments and in-law suites. You need building permits and inspections to create one, and every unit must be registered with the town. ### How much does a bathroom renovation cost in Newmarket?
It depends on the size of the room, whether plumbing moves, and the fixtures and tile you choose. The most reliable number is a quote for your bathroom. DDR prices each job after seeing the space and talking through the scope; request a quote online or call 647-991-8551.
