Building Permit Application Process

Learn about the specific drawings and documents you have to provide to apply for a building permit. 

• Residential construction projects
• Non-residential construction projects

It's strongly recommended that you work with a design professional such as an architect, professional engineer or qualified designer to create complete, compliant  and accurate drawings.

Standardized naming conventions for documents

Name your file using the short form name followed by underscore and then the property address. An example of an architectural drawing set would look like this: Architectural_1225 Trafalgar Road.

Help us process your application faster by following the document submission standards.

Submission standards

1. Organize drawings and documents as separate files. Each document file can contain multiple pages if you are submitting a set of architectural drawings. Forms should be submitted as single documents.
2. Orient drawings in landscape. Orient forms and documents in portrait.
3. Save files in Vector PDF format, unlocked/editable, greyscale, flattened into a single layer and free of comments. Tip: To convert drawings created in AutoCAD to vector PDF, use Autodesk Vector Graphic Converter “DWG to PDF.pc3 plotter”.
4. Submit searchable PDF files for calculations, reports and other supporting documents (non-drawing files), when possible.
5. If including scanned documents, resolution of 1-bit black-and-white 300 dpi is usually acceptable. For plans and drawings with fine lines and detail, 600 dpi resolution is required. Full-colour renderings and photos may be submitted, but only as supplements to a sufficient set of plans. Grayscale is preferred.
6. Naming conventions: Please name your files according to the standardized naming conventions. This saves significant time in processing your application.
7. Resubmissions: Use bubbles to denote changes to the drawings and include a response letter detailing how review comments have been addressed. Remember to coordinate changes to drawings that impact other disciplines and supporting documents.

Once payment is received, your application will progress through a series of reviews. We will provide you with a courtesy status update after each type of review is complete and provide a list of deficiencies that require attention, if applicable. 

Once all examinations are complete and requirements are satisfied, you will be issued a building permit.

Refusals and resubmissions

If there are issues with your application, you will be provided a notification letter summarizing the deficiencies to be addressed. At this point, you are eligible to resubmit your revised plans that address the deficiency issues. 

Building inspections are required at various stages of construction under the Ontario Building Code to ensure all construction is done in accordance with approved plans. 

Go to the Building Inspections page to learn about the inspection process.
