THE PROBLEM

An unfinished basement in Oakville — or a house you've outgrown — is wasted potential.

Most Oakville homeowners delay because the process seems complicated — permits, zoning, contractors who disappear after the deposit. But every month you wait is rental income or living space you're not getting.

The process is only complicated when nobody manages it properly. We manage everything — for both basements and additions.

📋

Permit Confusion

Most homeowners don't know what permits are required, what drawings are needed, or how to submit through Oakville's ePlan system.

⚠️

Zoning & Code Gaps

Egress, fire separation, parking, unit count — Oakville's Additional Dwelling Unit provisions (By-law 2024-053) set different rules for detached, semi-detached, and townhouse properties.

💸

Unpermitted Work Risk

Work done without permits creates liability at resale and can force expensive corrections when buyers or inspectors find it.

📅

Lost Time, Lost Money

Every month of delay is rental income you're not collecting, or space your family still doesn't have.

OAKVILLE PERMIT PROCESS

Exactly how we get your legal basement suite or home addition approved in Oakville.

Oakville's Building Services department is based at 1225 Trafalgar Road, and can be reached at 905-845-6601 — but you won't need to call them. We do.

Under Ontario's Building Code Act, house-class permit applications carry a legislated municipal review standard of 10 business days once a submission is deemed complete. Oakville processes applications through its ePlan system, powered by ProjectDox, from submission to final occupancy.

✓Step 1 — Confirm what you can build. We check your property against Oakville's Additional Dwelling Unit provisions (By-law 2024-053) and zoning map before you commit to anything.
✓Step 2 — ePlan submission. We prepare your drawings and documents to Oakville's submission standards and upload your complete application through ePlan.
✓Step 3 — Pre-screening. The Town screens your submission for completeness and issues a $100 non-refundable pre-screening deposit invoice, credited toward your final permit fee.
✓Step 4 — Plan examination. Your application enters technical review against the Ontario Building Code and Oakville's Zoning By-law — house-class applications carry a legislated 10-business-day municipal review standard once complete.
✓Step 5 — Permit issuance. Once approved, you pay the balance of your permit fee (minimum $200) and receive your stamped permit package through ePlan.
✓Step 6 — Construction, inspections & occupancy. We complete all work, book every required inspection with Building Services, and confirm final sign-off — your space is officially legal and ready to use.

Oakville Questions

Everything you need to know before your free assessment.

Most homes qualify, but it depends on ceiling height, egress, fire separation, and your property type. Oakville's Additional Dwelling Unit by-law (2024-053) permits up to 3 ADUs on a detached dwelling lot, or up to 2 on semi-detached, linked, and townhouse properties. We confirm exactly what your property qualifies for at your free assessment.

We do — start to finish. We submit directly through Oakville's ePlan system and manage every inspection with Building Services, so you don't deal with the Town at all.

House-class permit applications carry a legislated 10-business-day municipal review standard under the Ontario Building Code, once your submission is deemed complete. Construction time depends on project scope — we'll give you a specific schedule at your free assessment.

It depends on how many ADUs are on your lot. Under By-law 2024-053, the first two units on a lot each require one parking space; a third ADU does not require additional parking. We'll confirm exactly what applies to your property.
