How to Get a Building Permit in Ottawa

Planning a renovation or addition to your home in Ottawa? Whether you're remodeling a kitchen, adding a deck, finishing a basement, or building a second story, you’ll likely need a building permit. The City of Ottawa enforces permit requirements to ensure all construction projects meet safety, zoning, and building code standards. Understanding the permit process can save you time, prevent costly mistakes, and ensure your project is fully compliant from start to finish.

This guide outlines the step-by-step process for getting a building permit in Ottawa and provides helpful links to official city resources.

When You Need a Building Permit in Ottawa

In Ottawa, you typically need a building permit for any project that alters the structure or systems of your home. Some common projects that require a permit include:

• Kitchen renovations: if changes involve plumbing, electrical, or structural components
  
  
• Bathroom renovations: especially when adding or moving fixtures
  
  
• Basement renovations: when converting storage space into livable areas
  
  
• Second story additions: any vertical expansion of your home
  
  
• Sunroom additions: enclosed porches or glass additions
  
  
• Attic conversions: turning unused attic space into bedrooms, offices, or rentals
  
  
• Decks: if attached to your home, elevated, or larger than 10 square metres
  
  

If your work is purely cosmetic—like painting, replacing flooring, or installing kitchen cabinets without plumbing or electrical changes—a permit may not be required. However, your project must still follow all applicable bylaws and building codes.

Step 1: Pre-Application Consultation (Recommended)

Before applying, it’s strongly recommended to consult with the City of Ottawa’s Building Code Services or Zoning Information Services.

A pre-application consultation helps you:

• Confirm whether your project needs a permit
  
  
• Identify any zoning issues, setbacks, or height restrictions
  
  
• Understand which documents and approvals are required
  
  
• Avoid delays due to incomplete submissions
  
  

You can schedule a consultation by calling 3-1-1 or visiting a Client Service Centre.

Step 2: Prepare Your Application

Once you’re ready to apply, gather the required documents:

• A completed Building Permit Application Form (PDF)
  
  
• Detailed, to-scale construction drawings showing:
  
  
  
  • Floor plans and elevations
    
    
  • Structural framing and materials
    
    
  • Site plan with setbacks, property lines, and existing buildings
    
    
• Proof of property ownership or written authorization from the owner
  
  
• Any required supporting approvals (e.g., Heritage Permits, minor variances, or site plan control)
  
  
• Payment for permit fees, calculated by area and project type (view fee schedule here)
  
  

For complex projects, you may need architectural or engineering drawings signed by a licensed professional.

Step 3: Submit Your Application

You have three submission options:

Online:
Use the City of Ottawa's online application portal via your MyServiceOttawa account. Upload all documentation and pay fees electronically.

In Person:
Visit a City of Ottawa Client Service Centre with printed plans and forms. Staff will review and process your submission.

By Mail:
Mail your completed forms, drawings, and fee payment to:
City of Ottawa – Building Code Services
100 Constellation Drive
Ottawa, ON K2G 6J8

Online submissions are typically faster and more efficient.

Step 4: Application Review and Response

Once submitted, the City will review your application to ensure it complies with:

• The Ontario Building Code
  
  
• Zoning By-law 2008-250
  
  
• Other applicable regulations, such as fire code, environmental protection, or accessibility standards
  
  

The review process may involve multiple departments. If your submission is incomplete or doesn’t meet requirements, you’ll receive a request for corrections.

If your application is approved, the City will issue your building permit—either electronically or in person depending on your submission method.

Step 5: Permit Issuance and Inspections

Once issued, your building permit must be:

• Posted visibly at the construction site
  
  
• Available for review by City inspectors
  
  

You must book inspections at various stages of your project, which may include:

• Excavation and footings
  
  
• Framing and structural elements
  
  
• Plumbing and electrical rough-ins
  
  
• Insulation and vapour barrier
  
  
• Final occupancy inspection
  
  

You can schedule inspections through Ottawa's online inspection portal or by calling 3-1-1.

Step 6: Completion and Final Inspection

After the construction is complete, request a final inspection. If your project passes, the permit file will be officially closed and the work approved for use.

Keep your permit documents and inspection records as they may be requested during a future sale, refinance, or insurance claim.

Additional Tips

Permit Timelines:

• Simple projects (like a deck or minor reno) may be approved in 5–10 business days
  
  
• Complex projects (like second stories or new builds) can take 30+ days
  
  

Common Causes of Delays:

• Missing or inaccurate drawings
  
  
• Zoning issues (e.g., setback violations)
  
  
• Outstanding approvals (e.g., heritage or conservation area)
