Basement Renovations in Burlington
From Aldershot and Tyandaga to Headon Forest, Millcroft and the Orchard, we finish Burlington basements and build additional residential units, starting with the City's zoning clearance.
Zoning Clearance Comes First
In Burlington, a basement unit starts with zoning, not with the building permit. The City's Pre-Building Approval process issues a Zoning Clearance Certificate, and only then can the building permit application go in. For 2026 the zoning review fee is $1,145 for an accessory dwelling unit and $400 for a basement finish. Burlington's zoning checklists now cover both the new residential By-law 09-2026 and the older By-law 2020, so we confirm which one applies to your lot.
The parking rules are generous for a first unit. The City requires two spaces for the main home, none for the first additional unit and one for a second or third. It also cautions that not every property can have an additional unit, which is why the zoning check happens before any drawings are finalized.
Burlington's housing stock is mature: 47.4% of homes were built before 1981, and a third between 1961 and 1980, according to the 2021 census. Basements of that age often need new insulation, wiring and flood protection before they are finished. The City's ARU Incentive Program closed on October 1, 2025, so the help available today comes through flood-prevention programs instead.

Interior alterations to a house are $8.25 per square metre, with a $377 minimum permit fee.
Flood Permit Fee Grant

What a Burlington Basement Costs
Our Burlington basement finishing starts at $55 per square foot, and additional residential units start at $80 per square foot. Expect most standard finishes to fall between $50,000 and $90,000. A legal unit usually costs $80,000 to $175,000, covering the kitchen, fire-rated separation, interconnected alarms, egress, zoning clearance, permit and inspections.
In older Burlington homes, moisture and electrical work are the usual extras, and we show them as separate lines. Halton Region's subsidies and the City's permit fee waiver can offset part of the flood protection work. You get a fixed, itemized price after a site visit, so the full cost is known before anything starts.
