Garden Suites & ARUs in Vaughan
As expert Garden Suites Vaughan builders, we start every project with a zoning and feasibility review specific to your property, then carry that same team through design, permits, and construction. Under By-law 083-2025, most eligible lots can support up to two additional residential units — a basement apartment paired with a detached garden suite depending on lot size — and we help you figure out which combination Woodbridge, Maple, or Kleinburg lots genuinely support. See our ARU / Garden Suites page for full process detail.

How We Handle Zoning & Design for Vaughan Garden Suites
We confirm your property’s frontage, suite size, and parking eligibility before proposing a design — By-law 083-2025 caps most eligible lots at two additional residential units, generally requiring a minimum 9-metre lot frontage and roughly three parking spaces. Because Vaughan’s Comprehensive Zoning By-law remains under Ontario Land Tribunal appeal, we also verify whether the older Zoning By-law 1-88 applies to your specific property before finalizing any design.
Frequently Asked Questions
How many additional units can I add to my Vaughan property?
We confirm this for your specific lot — Vaughan currently permits up to two additional residential units per eligible lot, which can include a basement apartment and a detached garden suite.
Can I build a detached garden suite in Vaughan?
Potentially — we confirm eligibility during feasibility review, since larger established lots in areas like Woodbridge and Maple tend to have more flexibility.
Why does it matter which Vaughan zoning by-law applies to my property?
We confirm this before finalizing any design, since requirements can differ between the newer Comprehensive Zoning By-law and the older By-law 1-88, which still applies to some properties.
How long does a garden suite project take in Vaughan?
Typically 8 to 14 months from initial design through construction completion for our projects, including permit review, with permit timelines being the most variable factor.
