This guide outlines the general steps required to obtain a building permit in Ontario and explains the importance of professional documentation and expert support in the permit process.

What is a Building Permit?

A building permit is an official document issued by your city or local municipality that authorizes you to begin construction, renovation, or demolition. It ensures that the work complies with the Ontario Building Code, zoning by-laws, and other relevant regulations.

Projects That Typically Require Permits

Most construction or structural changes will require a permit. These include:

• New home construction

• Home additions

• Garage or deck additions

• Interior renovations that affect structure, plumbing, or electrical

• Basement finishes with new bedrooms or washrooms

• Demolition of existing structures

• Secondary dwelling units or basement apartments

Step-by-Step: Building Permit Process in Ontario

While every municipality in Ontario may have slight procedural differences, the core steps remain consistent across the province:

1. Determine Whether a Permit is Required

Before starting any construction work, confirm whether your project needs a permit. Even seemingly minor renovations may require approval if they affect structure, plumbing, or electrical systems.

2. Zoning & Property Research

Ensure your project complies with local zoning by-laws, which regulate aspects such as building height, setbacks, lot coverage, and permitted uses. Zoning conflicts may require a separate variance application or additional approvals before a permit can be issued.

3. Develop Permit-Ready Drawings

Create detailed architectural and structural drawings that reflect the intended scope of work. These must align with the Ontario Building Code and meet the submission standards of your local municipality.

At BEIN Design, our in-house team produces fully permit-ready drawings tailored for quick municipal approval.

4. Prepare and Submit Your Application

Complete the standard building permit application forms. Submissions typically include:

• Permit application form

• Construction drawings (architectural, structural, mechanical)

• Site plan

• Energy efficiency documents (SB-10 or SB-12 compliance)

• Application fees

Applications are usually submitted online through municipal e-portals, or in some cases, in person.

5. Building Code Review & Municipal Review

Once submitted, municipal staff will review your documents to ensure the project meets the Ontario Building Code, zoning by-laws, and applicable laws (such as the Conservation Authorities Act or the Planning Act).

Delays often occur due to incomplete documentation or code compliance issues—this is why professional support and a code-compliant set of drawings are critical.

6. Permit Issuance

Once all documents are approved, you’ll be issued a permit and can begin construction. The permit must be posted visibly on the site, and all work must follow the approved plans.

7. Required Inspections

During construction, inspections will be required at various stages (e.g., footings, framing, insulation, occupancy). Inspections ensure the work complies with the approved plans and building code.
