Apply for site plan approval

If you’re planning construction of a new building or addition, and the property is subject to site plan control, you’ll need to apply for site plan approval.

The purpose of site plan approval is to review the location and design of buildings and structures, maintain urban and landscape design guidelines, and include sustainable design standards.

To find out if you need site plan approval, you can call 311 (905-615-4311 outside City limits) or check the property information online.

If you applied for site plan approval before January 1, 2016. Use our development application tool to check the progress of your application.

All site plan applications must be submitted online through ePlans.

Online application process

1. Create account and submit pre-application meeting request

Start by creating an ePlans account. Then log into ePlans and follow the steps to submit your pre-application meeting request, which includes uploading your drawings and documents.

You should submit the following drawings and documents with your pre-application meeting request for site plan approval:

  1. Site plan, including the following:
    • Building footprint and dimensions (existing and proposed)
    • Building setbacks from all lot lines (existing and proposed)
    • Site statistics (for example lot area, existing and proposed gross floor area, parking required and provided)
    • Landscaped areas/buffers and dimensions
    • Site access, driveway location, parking areas and dimensions
  1. Elevation drawings with height dimensions (for example floor-to-floor and overall building height)
  2. Floor plans, survey plan and images of the property and surrounding area, if available
  3. A cover letter which includes the applicant and property owner name, brief description of the proposal and who will be attending the meeting

Drawings and documents should be saved in the correct view orientation.

File names for all drawings should include the first letter of the discipline name, such as “A” for architectural, followed by the three digit sheet number and drawing type. For example, “A100 Site Plan”.

Each drawing plan sheet should be an individual file.

Make sure to use the “Complete – Notify the City of Mississauga” button to submit your request.

Once we receive your pre-application meeting request, we’ll review the drawings and documents you’ve submitted, tell you what additional information is required, or any changes that should be made.

We’ll also let you know what type of site plan application you need, which is usually one of the following:

  • Standard Site Plan Application
  • Limited Site Plan Application
  • Site Plan Approval Express
  • Infill Housing (new dwellings, replacement housing and additions)
  • Development Not Subject to Site Plan Approval

For certain types of site plan application we may not need to meet you for a formal pre-application meeting. We’ll let you know if you need a meeting within five to seven business days of your request.

All feedback will also be available for you to view in ePlans.

When you’re ready to submit your site plan application, log into ePlans and follow the steps to create a site plan approval request and pay the administration fee.

Shortly after submitting your site plan request, you’ll receive an email that includes your temporary project number and an invitation to upload the required site plan documents.

Guidance documents

View the terms of reference documents for an explanation on the information required for each study, report or plan submitted as part of a site plan application.

3. Prescreen review

After you upload the drawings and documents, we’ll do a prescreen review to ensure the requirements are met. This usually takes three to five business days.

If we still need more information, we’ll email you. All prescreen corrections will need to be made by you in order to move ahead with the application process.

4. Pay fees

After the prescreen review, you’ll receive a “fee payment task” email with instructions on how to pay your fees.

Once you’ve paid the fees, your application will be created and we’ll email you an application number.

5. Department review

Your application will be reviewed by the relevant City departments and agencies to make sure it meets all the requirements. You can view all of the comments in your “Project Status Report” in ePlans.

Resubmit revised or more information

If any of the review groups have withheld your application you will need to resubmit revised or additional information. We’ll send you an “applicant resubmit” email telling you what to do next.

6. Your site plan is approved

Once your application is approved by all the review groups, you’ll be notified via email that your stamped and approved plans are available to download in ePlans. Site plan approval is valid for one year from the date shown on the plans.

We’ll also forward your site plan approval to the Building Department so they have it on file when you’re ready to apply for your building permits.
