The Ultimate Guide to City of Burlington Building Permits (2026)

Whether you're legalizing a basement apartment, adding a secondary suite, or undertaking a commercial renovation, navigating the City of Burlington's building permit process is a critical first step.

Burlington has recently updated its systems, introducing AI-assisted drawing reviews and a dedicated pre-approval stage that homeowners across the GTA don't always expect. At Ontario Design Studio (ODS), our BCIN-certified experts specialize in creating permit drawings that cut through the red tape. Here's exactly what you need to know to secure your building permit in Burlington this year.

Do You Need a Building Permit in Burlington?

Under the Ontario Building Code (OBC), Burlington requires a permit for any project that affects a building's structure, life-safety systems, or adds new floor area. You must obtain a permit for:

• Additional Residential Units (ARUs): Legal basement apartments, secondary suites, and detached garden suites.
• Additions and major renovations: Removing load-bearing walls, underpinning basements, or second-storey additions.
• Decks: Any deck attached to the house, larger than 10 square metres (108 sq. ft.), or higher than 24 inches above grade.
• Accessory structures: Sheds or detached garages over 108 sq. ft., or any structure containing plumbing.

If you proceed without a permit, the City of Burlington enforces strict penalties: stop-work orders, fines of up to $50,000 for individuals under the Ontario Building Code Act, and forced removal of completed work.

2026 Burlington Specifics: eCheck & Zoning Clearances

Burlington handles permits slightly differently than other GTA municipalities. You must follow their specific multi-stage process.

1. The Pre-Building Approval (Zoning Clearance Certificate)

In Burlington, you cannot simply submit a building permit application right away. For residential projects like ARUs, decks, and additions, you must first obtain an approved Zoning Clearance Certificate (also known as Pre-Building Approval).

• This ensures your proposed use, setbacks, lot coverage, and building height comply with the applicable Burlington Zoning Bylaw.
• Once approved, this certificate is valid for one year. You must apply for your actual building permit within that timeframe.

2. The City's "eCheck" AI Tool

Burlington has introduced eCheck, an online tool that uses artificial intelligence to pre-screen architectural drawings before formal submission.

• For single-detached homes, it scans your floor plans to verify Ontario Building Code requirements like ceiling heights, room sizes, and fire protection criteria.
• It generates a pass/fail report, allowing applicants to fix errors before entering the official queue.

Note: While eCheck is helpful, it does not replace the legal requirement for your drawings to be prepared by a qualified BCIN designer or architect.

The Burlington Permit Process: Step-by-Step

1. Apply for a Zoning Clearance Certificate - required before your full permit application. We submit your initial concept to the city to verify it meets Burlington's zoning bylaws (setbacks, height, lot coverage). We cannot proceed to the building department until this is approved.
2. Prepare BCIN-certified permit drawings - the ODS phase. The city requires highly detailed, scaled architectural drawings. As BCIN-certified designers, ODS prepares comprehensive site plans, floor plans, elevations, and cross-sections tailored specifically to your property and the Ontario Building Code.
3. Run drawings through eCheck - optional but recommended. We can utilize Burlington's eCheck AI system to verify room dimensions and fire separation criteria, ensuring a smoother review process with city examiners.
4. Submit the electronic application - Burlington requires all submissions to be strictly electronic. We package your drawings, the Application for a Permit to Construct or Demolish, and your approved Zoning Clearance Certificate, ensuring all files meet the city's strict naming conventions.
5. Construction and milestone inspections - once issued, your permit will not expire as long as you start construction within 6 months. You must book mandatory City of Burlington inspections at specific milestones (framing, plumbing, final completion) to officially close the permit.
