Some renovation, construction or demolition projects require a development engineering permit.
Your project must meet zoning regulations even if it doesn’t require a building permit.
It is illegal to start construction before receiving a building permit.
Before you begin
As of November 28, 2022, if you have a residential development that is 10 units or less, please submit your Building Permit Application to the Building Services department.
If additional works are proposed outside of the building footprint, additional permits may be required. This includes but is not limited to site alteration, road cuts, driveways and pools. Please refer to the Grading and Servicing Plan Guide for Residential Infill Developments (pdf).
If you have a residential development of more than 10 units, please submit your Planning Application to the Planning department.
When your project is complete, request an inspection
Upon completion of your project, a request for inspection may be submitted using our online services.
Follow these steps or watch our How to Request and Inspection for your Development Engineering Application video on YouTube.
Grading inspections cannot take place if the ground is snow covered and tree inspections cannot be completed until trees are in full leave (approximately May to October).
- To request an inspection for an already issued Development Engineering Permit, select the “Activity” button beside the applicable permit.
- Select the “Inspections” tab and select the applicable inspection type you wish to request.
- Upload the required inspection documents. A final Lot Grading Certification is required from the site surveyor to verify they have been on site within the past 30 days of the dated letter, and that the works have been carried out in accordance with the plan. Site photos must be included with submission of the LGC. Review some Lot Grading Certificate samples (pdf)
- Provide any special instructions to the inspector(s).
- Your inspection request has now been provided. Grading inspections cannot take place if the ground is snow covered and tree inspections cannot be completed until trees are in full leave (approximately May to October).
- Once your inspection has taken place, you will be notified via email of the results. If the result of the inspection is “Not Passed”, you will need to address any deficiencies noted in the email provided and then request a new inspection following the steps provided above.
Application fees include a maximum of two inspection visits. Additional inspection fees will be charged after the two failed inspections.
Securities collected on the permit will only be released once all required inspections have passed.
