Navigating the Building Permit Process in Ontario: A Comprehensive Guide by Dar Architects

At Dar Architects, we specialize in guiding homeowners, developers, and investors through Ontario's intricate building permit process. Whether you're planning a custom home, secondary suite, duplex, triplex, fourplex, or garden suite, understanding the steps involved in zoning review, minor variance applications, and permit approvals is crucial for project success.

Below, we outline the comprehensive process for obtaining building permits, including zoning reviews and minor variance applications, across Ontario cities in the GTA, Simcoe County and Beyond

1. Zoning Review Process

Before applying for a building permit, ensure your project complies with your municipality's Zoning By-law.

Application Process:

  • Submit a request for a Zoning Certificate or Preliminary Zoning Review.

  • Provide project details: site address, proposed use, number of units (e.g., duplex, triplex), and any additions (e.g., garden suite).

  • Await confirmation from the municipality regarding compliance with zoning regulations.

Required Documentation:

  • Site Plan

  • Floor Plans and Elevations

  • Survey or Property Boundaries

  • Description of Proposed Use

If your development complies, proceed with the building permit application. If not, apply for a Minor Variance.

2. Minor Variance Application Process (Committee of Adjustment)

If your project requires relief from specific zoning provisions—such as height limits, setbacks, or maximum floor space—you'll need to submit a Minor Variance application to your city's Committee of Adjustment (COA).

Application Process:

  • Submit an application to your city's COA.

  • Include a justification report detailing the need for the variance.

  • Attend a public hearing where community feedback is considered.

  • Await the committee's decision (approval, denial, or deferral).

Required Documentation:

  • Completed Minor Variance Application Form

  • Zoning Certificate or Preliminary Review Results

  • Site Plan and Floor Plans

  • Elevations

  • Planning Justification Letter

  • Photos of the Existing Property

  • Supporting Documents (e.g., survey, deed)HeyTony

Cities like Toronto, Markham, Richmond Hill, Bradford, and Barrie have specific forms and procedures.

3. Building Permit Application Process

Once your project complies with zoning or has received minor variance approval, you can apply for a Building Permit.

Application Process:

  • Submit your building permit application to the local building department.

  • Include technical drawings stamped by a licensed architect (like Dar Architects).

  • The plans examiner reviews the submission for code compliance.

  • Upon approval, permits are issued, and construction may commence.

Required Documentation:

  • Architectural Permit Drawings (Site Plan, Floor Plans, Elevations)

  • Structural Drawings

  • Mechanical Drawings (HVAC, plumbing)

  • Energy Compliance Forms (SB-10 or SB-12)

  • Building Permit Application Form

  • Payment of Application Fees

At Dar Architects, we prepare and submit all required drawings and documentation, ensuring a seamless experience from concept to permit approval.
