Inspections - Building, Plumbing and Fire Protection
Inspections can be arranged by calling 519-661-2489 x 5287, emailing email@example.com or through the Development and Business Portal (E-Portal). Any inspection requests that do not meet the restriction criteria will be cancelled. For select inspections types, platforms such as FaceTime and WhatsApp are available, please contact your inspector for more information.
Restriction criteria for inspections
For inspections under a new-erect permit, inspectors will announce their arrival and ask that all tradespersons vacate the building (single/semi-detached dwellings, row townhouses), including attached garages. Only thereafter, will the inspection be conducted.
Anyone that may want to speak to the inspectors on site is requested to adhere to a 2 metre safe distance limit. Should the inspectors determine that this is not followed, on a discretionary basis, they will leave the premises.
Inspections for residential additions, single detached dwelling/row townhouse alterations
Inspections are conducted for small residential buildings under renovation with a permit issued for alterations.
If you have requested an inspection under a building permit for alteration work and have not provided us with a site contact phone number, please reply to firstname.lastname@example.org and provide it so your inspection date is not compromised. This allows the inspector to be able to call on the date of the inspection.
- It is your responsibility to ensure the inspector is able to successfully connect with the person assigned this number in order that the inspection be carried out.
- If the inspector calls, and there is no answer, he/she will attempt to knock on the front door. If no one answers, the inspector will leave and record the inspection(s) as ‘“Inspection cancelled by City”. You will then be required to rebook the inspection(s).
- As a result of the above, when the inspector attends for the second time, he/she will attempt contact by phone only.
- If upon inspection, the inspector finds that the work is not ready or previously identified deficiencies have not been rectified, the inspection will be deemed as “Not ready” and you will need to remit the associated fee. Currently, that amount is $178.68 and indexed annually March 1.
The following site restrictions must be adhered to:
- At all times during the on-site physical inspection, and after the inspector has confirmed arrival, all other tradespersons are to vacate the area under renovation. Only upon confirmation of this, will the inspector enter.
- Anyone wishing to speak to the inspector must do so at a minimum distance of 2 metres.
- The area under renovation must be separated from the remaining dwelling by use of a full-height temporary partition or a curtain consisting of fabric or vapour barrier material.
- When the inspector arrives, he/she will call the number given previously and confirm that, if for any reason, occupants (not tradespersons) must remain in the dwelling, the permit holder/homeowner shall provide confirmation via text message (must include the address) to the inspector, prior to the inspection, that all occupants have answered ‘No’ to all of the following questions:
Do you have any of the following symptoms (new or worsening) that are not related to seasonal allergies or pre-existing health conditions?

For select inspection types, platforms such as FaceTime and WhatsApp are available. Please contact your inspector for more information.
Inspections for partial occupancy permits
Inspections are conducted for partial occupancy permits.
The following protocol must be adhered to for partial occupancy inspections:
- Contact will need to be made by the site supervisor (site super) to the inspector prior to attendance.
- A mutually agreed-upon location on site is to be arranged for the inspector and the site super to meet, if there is no job site trailer available.
- The site super is to ensure the path of travel to the inspection area will be such that the 2 metre physical distance requirement from the inspector, is adhered to at all times.
- The site super is to ensure that any elevator usage is restricted to the inspector and the site super only.
- If stairs are used to enter the floor area(s) to be inspected, the site super shall ensure the stairs are mark for one way travel only (For example: west stairs ascending only and the east stairs descending only).
- For the floor/area being inspected, the site super is to ensure that there are no tradespersons present. If this is not possible, all tradespersons are to maintain the physical distance requirement from the inspector at all times while he/she is there.
- At the end of the inspection(s), the site super must accompany the inspector off the site while maintaining the physical distance requirements.
The inspector may not commence or terminate the inspection at any time, if the above protocol has not been complied with. The permit holder will receive a “Inspection Cancelled by City” notice via email and will need to re-book the partial occupancy inspection.
