Title description, April 18, 2025

Planned a construction project in Hamilton? From building decks, extensions and extensions, renovating basements or starting new construction, permits are typically required to ensure compliance with local building codes, zoning bylaws and safety standards. While the permit application process may seem complex at first, when broken down into steps it becomes much simpler – here is our quick guide on getting a building permits Hamilton.

Step One: Determine If You Require A Permit

Not every project requires a building permits Hamilton; therefore, the first step should be identifying whether yours does. In Hamilton, permits may be needed for projects including:

• New construction (homes, garages and additions)
• Structural modifications (such as demolishing load-bearing walls or installing windows or doors)
• Decks over a certain height that require plumbing or HVAC changes
• An expanded basement space

Painting, replacing cabinets or minor repairs typically do not require permits in Hamilton City; when in doubt however, use the City of Hamilton Building Division or their online tool to verify if one is necessary.

Step Two: Gather Your Application and Drawings for Submission.

Once it becomes evident that a permit is necessary, the next step should be gathering all necessary materials for application. These might include:

• Completed Building Permit Application Form.
• Two sets of construction drawings (floor plans, elevations and site plan)
• Should a property survey be required, one will likely be conducted.
• Additional forms such as HVAC or plumbing documentation (if applicable).

When dealing with larger or more complex projects, an architect or designer may be necessary. All documents should comply with Ontario Building Code regulation for building permits Hamilton s as well as Hamilton’s Zoning Bylaws.

Step Three: Submit Your Application

Your completed application and documents may be submitted either electronically through the City of Hamilton’s ePLANS portal, or in person to their Building Division office. Online submission may be quicker and more convenient; fees vary based on project scope/size so it is best to contact their office directly for an estimate of fees associated with your project.

Step 4: Review of Application and Issuance of Permit

After you submit, the city’s building department will review your application to ensure compliance with zoning laws, building codes, fire safety standards and engineering standards. If anything is missing or unclear they may request revisions; in general this review process takes about 10 business days for residential permits but this can vary depending on its complexity.

Once your application has been accepted, a City of hamilton building permits will be issued granting legal permission to begin construction on your project. In addition, you’ll be given a permit card which must be displayed visibly at your construction site.

Step 5: Arrange for Inspections during and After Construction

After receiving your building permits Oakville, the next step should be scheduling inspections at various stages of your project to make sure it’s being done according to code and as approved in your permit. 

These may include:

• Footings and foundation, framing, plumbing and electrical work.
• Final Inspection Both you and your contractor can book final inspections through the city portal or calling the building division directly. 
• Don’t skip inspections–they are mandatory!
