Our Garden Suite Design & Permits Process in Oshawa

A clear, step-by-step process that keeps you informed and your project on track from start to finish.

Feasibility Study
We review your Oshawa lot against the zoning bylaw — setbacks, coverage, height, trees, and servicing — and report exactly what you can build, or whether a variance would be needed.
Concept Design
Working from the feasibility findings, we develop a suite concept with you — layout, storeys, and orientation — refined until it fits both your lot and your plans.
Permit Drawings
Our team produces the full architectural package, coordinates structural engineering and energy compliance, and assembles everything the building department requires.
Permit Application
We submit the application to the City of Oshawa Building Services and manage the review — responding to examiner comments and handling revisions until the permit is issued.
Handover or Build
You receive the complete permitted package, ready for any qualified builder — or roll it directly into a Home Garden Suites design-build contract and keep the same team through construction.

Garden Suite Design & Permits FAQs — Oshawa, ON

Answers to common questions about garden suite design & permits in Oshawa.

Our design and permits package in Oshawa runs $15,000 to $35,000, depending on the suite's size, whether it is one or two storeys, structural complexity, and whether any variances are involved. That covers feasibility, architectural drawings, engineering coordination, and the permit application through to approval.

We typically deliver a permit-ready package in 8 to 12 weeks, and municipal review at the City of Oshawa Building Services generally adds 2 to 4 months. Total time from engagement to an issued permit is usually 4 to 7 months, and a clean, complete first submission — our specialty — is the single biggest factor in staying at the fast end.

The Oshawa package includes a lot-specific feasibility study, concept design, full architectural drawings, structural engineering coordination, energy-efficiency compliance documents, and the building permit application itself — including responses to examiner comments until the permit is issued. You end up with a complete, permitted set of drawings.

That is exactly why the process starts with feasibility. The City of Oshawa permits additional residential units on most residential lots, with garden suite permits through Building Services. If your lot falls short on setbacks, access, or servicing, we tell you before you spend on full design — and where a minor variance or a smaller footprint would solve it, we lay out those options honestly.

Yes. The permitted drawing package is yours, and any qualified contractor can build from it. Because our designers work alongside our own construction team, the drawings are genuinely buildable — dimensions, structure, and servicing are resolved on paper rather than discovered on site. Many clients still choose to continue with us for construction, but there is no obligation.
