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.

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).
At the time of pre-screening, your application will be deemed to be either complete or incomplete. This will determine the initial review time of your BUILDING PERMIT application.
Complete application: Contains all required drawings and documents, meets ePlans submission standards, meets all applicable law, and all required approvals have been obtained
10 Days - Residential housing type applications,
new construction and alterations
20 Days - Non-residential applications
Timelines are measured from when the application is CREATED.
Incomplete application: may be missing drawings, documents, approvals, information, drawing may not contain sufficient information, identifies a non-compliance with Zoning By-law. Not subject to the prescribed review time.
Residential: AVERAGE 4 weeks
Non-Residential: AVERAGE 8 weeks
It is important to remember that processing times outlined above are the time to complete the initial (first) review of your application; it does not mean that your building permit will be issued within these times.
The AVERAGE length of a building permit application from application creation to issuance 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.
Application status & resubmission
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.
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
