Milton basement permits and legal suite rules
The Town of Milton requires a building permit to finish any portion of a basement, even for your own family's use. Inspections typically include framing, plumbing, insulation, heating and a final inspection, booked online as each stage is ready. The Town's minimum permit fee for any permit type is $264.20.
If you want a rental unit, Milton calls it an additional residential unit (ARU). ARUs are allowed in detached, semi-detached, semi-link and townhouses that meet the zoning by-law, and a basement unit may occupy the entire basement. Parking rules are in the zoning by-law. Under Milton's ARU by-law, every additional unit, new or existing, must be registered with the Town and renewed every year. The Town notes that it does not recognize a "legal basement apartment" just because it was built: it must be built to Code and registered.
Province-wide, the 2024 Ontario Building Code sets the minimum ceiling height for a secondary suite at 1.95 m (1.85 m under beams and ducts), and requires interconnected smoke alarms between units. For the full step-by-step, read our legal basement apartment guide.
Basements in Milton homes
Most Milton homes were built in the last 25 years, many with poured concrete basements, good ceiling height and rough-in plumbing already in place. That usually makes finishing simpler than in older homes. Common Milton projects are family rooms with a bathroom, home offices, gyms and basement apartments with a side or rear entrance.
