Building permits are required to protect the interests of both individuals and the community as a whole. By reviewing and approving building plans before any work is done, the city can ensure that your project meets:
The Ontario Building Code, which outlines design standards that are in place to retain health, safety, fire protection, and accessibility.
The following application types can be submitted in person at our Planning & Building Customer Service Centre. You will be required to provide 2 copies of drawings for residential applications and 3 copies for non-residential.
emergency plumbing & building repairs
occupancy prior to completion
Planning & Building Customer Service Centre
300 City Centre Dr
3rd Floor from parking elevators
Acceptable methods of payment include: cash, cheque, debit and credit card.
Before submitting an application request for a building permit, we suggest you consider the following:
Do I need a building permit?
Have I checked the zoning provisions for my area?
Do I need the services of a design professional? (architect, engineer, qualified designer)
Do I have complete drawings that show the existing and proposed work?
Have I checked that I comply with any other applicable law and obtained any other required approvals?
To submit a building permit application, you must provide drawings, documents and forms in accordance with the minimum application requirements found below. The application fee is also due upon application creation.
It is recommended that you acquire the services of a design professional (architect, engineer, qualified designer) to prepare your drawings and documents. For some residential projects, the home owner may prepare their own drawings, but this is not recommended.
All work indicated on your drawings must conform to the Ontario Building Code, Mississauga Zoning by-law and other applicable law (such as conservation authority, heritage, site plan approval).
Your initial request may take 3-5 business days to be “prescreened”.
If your request is accepted as a “complete” application, the first “department review” may take:
10 business days (residential applications)
15 business days (second units applications)
20 business days (non-residential applications)
“Incomplete” applications are not subject to the timelines listed above. Subsequent department reviews are not subject to the timelines above.
At the time of prescreening, staff will determine if your submission is “complete” or “incomplete”.
The amount of time required to obtain a permit will vary depending on the quality of the submission and how responsive the applicant is. The average length of time required to obtain a building permit is:
At the time of your application request you will be asked to pay an administration fee. This administration fee is non-refundable and will be credited towards your total building permit fee. Fees are required to be paid in full at the time of application creation.
Please note that there are penalties for starting construction before obtaining your permit.
There may be additional fees (development charges, etc.) and deposits (lot grading deposit, municipal services protection deposit, etc.) associated with your building permit application that may need to be paid prior to issuance. If applicable, these fees will be requested during the plan examination review.
Other approvals that may be required
If your property is subject to any of the following, you may have to provide a form of approval from the appropriate agency/department prior to your building permit being issued. It is best to provide this information at the time of your application request.
Site Plan Approval: Some properties within the City are subject to the "Site Plan Control" and site plan approval may be needed before a building permit can be issued. You may be required to submit a development application. Contact the Planning Division at 905 615 3200 x4165 for more information.
After the initial plan review, your “project status report” will be available in ePlans. This report will identify all of the outstanding issues that require action on your part. We may ask for more information or clarification on what was submitted. You will have to resubmit the requested information for a subsequent review; this is called making a resubmission or “applicant resubmit” in ePlans.
It is not uncommon for a building permit application to be reviewed morethan once prior to it being found acceptable for issuance.
If you have questions about the outstanding comments on your application, you should contact the examiner directly to discuss. All examiner contact information is located on your project status report.
TO OBTAIN THE STATUS OF YOUR APPLICATION YOU MUST LOG INTO EPLANS AND RUN THE "WORKFLOW-PROJECT STATUS REPORT"
All conditions placed on your application are subject to change until you have received the official plan review correction notice
Revisions are made when you are revising work that was approved on a permit that has already been ISSUED.
If you are submitting additional or revised information for your application that is still in process, this is not a “revision” see “application status & resubmission”.
REVISIONS TO ISSUED PERMITS:
Once your building permit has been issued, should you wish to revise construction or scope of work, you will require authorization from the Building Division. This may be in the form of a “field revision” authorized by the inspector(s), or a formal “revision application”. Please speak to your inspector(s) to determine the type of revision required.
Changes to the scope of work indicated in the original building permit application may be subject to the recalculation of building permit fees and/or an additional hourly review fee.
HOW TO APPLY FOR A REVISION:
The process of submitting a “revision” application is the same as submitting a new building permit request (see “application process”). The description of your revision permit should state “REVISION TO 18-####” referring to your original building permit.
Each revision permit shall be accompanied by:
- a covering letter summarizing and itemizing all the changes
- revised drawings and/or documents
- **NOTE: only submit drawings that reflect the revised work, do not submit drawings that do not contain changes.
Building permit history
You can search the history of building permits on a property by entering the address at the link below and clicking on the “building permits” tab.
As outlined in “application requirements”, each application must be accompanied by various drawings and documents.
Drawings should be drawn to scale. Drawings can be either in metric or imperial measurements.
Below are some sample drawings that illustrate the quality and information required. If you are not capable of preparing something of this quality, we recommend obtaining the services of a design professional (architect, engineer, qualified designer). These drawings are intended to illustrate quality and typical information required only. This is subject to change and may vary based on the scope of work and staff’s discretion. Additional information may be requested during plans examination.
Depending on the scope of work, the drawings submitted may need to bear the stamp of an architect, professional engineer, or qualified designer.
The SMART (structural, mechanical, architectural review team) is responsible for the Ontario Building Code review of building permit applications. Plans examinations are performed under the authority of the Ontario Building Code Act.
If you no longer wish to proceed with your construction project and would like to cancel your application or permit, please email the appropriate cancellation request form to firstname.lastname@example.org. Please note that an inspection may be required prior to cancellation.
On April 1, 2017, Region of Peel Council passed the Backflow Prevention By-law 10-2017. The purpose of the By-law is to prevent backflow into the Municipal Drinking Water System of The Regional Municipality of Peel for provisions of clean and safe drinking water.
Unless there are other specific requirements (ie: Conservation Authority, site specific zoning, Greenbelt restrictions, etc), the following information shall apply to the construction of all uncovered residential wood decks.
The purpose of this Code is to promote appropriate standards of behaviour, honesty, integrity and enforcement actions for City of Mississauga building officials and, to prevent practices which may constitute an abuse of power by the chief building official or inspectors in the exercise of a power or the performance of a duty under the Building Code Act and the Ontario Building Code.
