Woodbridge is Vaughan at its most established. East Woodbridge, Vellore Village, Sonoma Heights and Pine Valley homes come with generous basements that become bars, theatres, gyms and in-law suites finished to main-floor standard. For the fully custom end of that range, see our high-end basement finishing page.
As part of the City of Vaughan, Woodbridge projects run through Vaughan's ePlans permit system, which we file and manage for you. Whatever you start with, you end with finished square footage your family uses every week, and a number your Woodbridge house carries at resale.

Woodbridge falls under the City of Vaughan, so basement projects require a building permit filed through Vaughan's online ePlans portal. Planning a legal second suite? Vaughan permits additional residential units under By-law 082-2025: the unit may not exceed the gross floor area of the principal dwelling, with rules on parking and the separate entrance. Our licensed structural engineer prepares and stamps the permit drawings, and we file through ePlans and book every staged inspection (framing, insulation, ESA electrical, plumbing and final) so your project keeps moving.

Answers for Woodbridge homeowners
Do I need a building permit to finish my basement in Woodbridge?
Yes. Finishing a basement in Woodbridge requires a building permit, with staged inspections for structural, framing, insulation, electrical and plumbing work. Desire Basements has the drawings prepared and stamped by a licensed structural engineer, files the application, and manages every inspection through final sign-off.
Can I add a legal basement apartment in Woodbridge?
Yes. Under Ontario's updated housing rules, most urban residential lots in Woodbridge can now have additional residential units, including a basement suite, subject to local zoning. Suites must meet Building Code and Fire Code requirements for ceiling height, fire separation, egress and alarms. We design and build to full code and handle the approvals end to end.
