Legal Basement Apartments in Vaughan
As a basement finishing contractor working across Vaughan, we assess your basement’s specific conditions, confirm zoning eligibility, and manage the full permit process. Established neighbourhoods like Woodbridge and Maple, with their larger single-family lots, are often well suited to a compliant conversion, while some newer townhouse communities face tighter parking and frontage constraints — we check your specific lot against Vaughan’s eligibility criteria before proposing a design. See our Legal Basement Apartments & Basement Finishing page for our full process.
Why Vaughan Homeowners Choose Modinno
Vaughan’s eligibility rules — lot frontage, suite size limits, and parking requirements — are more specific than in many neighbouring cities. Homeowners choose us because we confirm eligibility against these exact criteria before any design work begins.

Egress windows, suite size, and fire separation designed correctly against Vaughan’s specific requirements.
One accountable team
Assessment, permits, and construction under a single contract, with no gaps between design and build.
Realistic timelines and budgets
Clear cost and schedule expectations set at the feasibility stage, before any construction commitment is made.
How We Handle Permits & Zoning in Vaughan
We check your lot’s frontage, suite size potential, and parking capacity before designing anything — Vaughan’s rules, recently updated by By-law 083-2025, generally require a minimum 9-metre lot frontage, a secondary suite between roughly 35 square metres and 45% of the main dwelling’s floor area, and three on-site parking spaces with a separate entrance. Because Vaughan’s Comprehensive Zoning By-law remains under appeal, we also confirm whether the newer by-law or the older By-law 1-88 governs your specific property before finalizing any design.
Frequently Asked Questions
What size lot do I need for a legal basement apartment in Vaughan?
We confirm your property’s specific frontage and zoning designation during feasibility review — Vaughan’s rules typically require a minimum lot frontage of approximately 9 metres.
How much parking do I need for a basement apartment in Vaughan?
We work this into your site plan from the outset — requirements generally call for three on-site parking spaces total, with a separate entrance for the secondary suite.
Which zoning by-law applies to my Vaughan property?
We confirm this before design begins, since some properties are still governed by the older Zoning By-law 1-88 while Vaughan’s newer Comprehensive By-law remains under appeal.
Do you handle the permit application with the City of Burlington directly?
Most of our projects take roughly 3 to 6 months from permit submission through final inspection, depending on existing conditions and scope of work.
