Legal Basement Apartments in Vaughan, Built to the City's Secondary Suite Bylaw
Vaughan is stricter than most GTA cities on parking and entrance placement. We check both before a single wall comes down, so your ePlans application doesn't stall halfway through.

Vaughan is stricter than most GTA cities on one specific point: parking. Under the City's Comprehensive Zoning By-law, most secondary suites need three total parking spaces on the property, not two, and the suite's entrance can't share a wall with the main house's front door.
Homeowners who skip past this rule often end up redesigning mid-project. We've built secondary suites across Vaughan, from Maple to Woodbridge to Thornhill, and parking and entrance placement are the first things we check before a single wall comes down.
Legal basement services in Vaughan
From the first zoning and parking check to final sign-off, every stage handled in-house.
Zoning & frontage review
We confirm your lot has the minimum 9-metre frontage required for a detached, semi-detached, or street townhouse suite, and size the unit correctly within Vaughan's limits.
Parking & entrance planning
Three total spaces in a driveway, garage, or carport, plus a separate side or rear entrance with a 1.2-metre walkway. We map this before design starts, not after.
ePlans permits
All drawings are prepared in-house and submitted through Vaughan's ePlans portal, already structured the way the City expects. ESA handles the electrical permit separately.
Suite construction
Built to the approved drawings with staged framing, electrical, and insulation inspections, and compliant with the 2026 Ontario Fire Code's expanded CO detection rules.
Basement renovations
Family rooms, home theatres, and in-law space, built to code from day one so converting to a registered secondary suite later doesn't mean tearing anything out.
Basement finishing
Flooring, drywall, lighting, trim, and bathroom or kitchen finishes, matched to the style of the rest of your Vaughan home.
What a permit-ready Vaughan suite needs
Permit fees run roughly $7.30 per square metre with a $195 minimum, plus a refundable $250 security deposit returned after your final inspection passes. Here's what has to be in place.
The two that stall most projects: three total parking spaces, and an entrance that doesn't share a wall with the front door. We design around both from the start.
- Three total parking spacesIn a driveway, garage, or carport, never the street, including what the main house already needs.
- Separate side or rear entranceCannot share a wall with the main dwelling's front door, reached by a walkway at least 1.2 metres wide.
- Minimum 9-metre lot frontageRequired for a detached, semi-detached, or street townhouse secondary suite.
- Size within limitsUp to 45 percent of the home's gross floor area, with a 35-square-metre minimum, and no more than two bedrooms.
- ePlans submissionAll building permit applications go through Vaughan's online portal; paper submissions aren't accepted.
- 2026 Fire Code complianceExpanded carbon monoxide detection and a new annual alarm inspection standard, with on-the-spot fines now possible.
