For new residential (single/semi/townhouses) erects, inspectors will call the site contact number to indicate an approximate time of arrival.    The site contact will be advised to ensure that ALL persons in the building (including attached garages) are to vacate.  Upon arrival at the site, prior to entering the building, the inspector will be expecting to find the building completely vacant.  Three phone call attempts will be made within a 15 minute timeframe.   Failure to make contact will result in the inspector attending and advising that the building be vacated.   The site contact will be advised by the inspector that for subsequent inspections, it is expected that they monitor their phone and answer the inspector’s incoming call to ensure the building is vacated prior to the inspection.  

For inspections where no site contact is available:  

For new residential (single/semi/townhouses) erects,  the inspector will arrive and announce their arrival so that the building can be vacated. The inspector will return to his/her vehicle and allow 10 minutes for the building to be vacated.   If, after 10 minutes, there is evidence that the building has not been vacated, the inspector will leave without conducting the inspection and enter a ‘Not Ready-Fee’ attempt result.

All not ready fees referred to above will be implemented on inspections conducted after January 31, 2021.

Please note that any talkback or complaints to the inspector about the inspection protocols in place, would qualify as ‘interfering with the work of an inspector’ and will be deemed as a reason for the inspector to leave the site and have the inspection attempt result listed as ‘Not ready fee’.      

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 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 epermits@london.ca 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.

Please note: 

• 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:

1. 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.
2. Anyone wishing to speak to the inspector must do so at a minimum distance of 2 metres.
3. 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.
4. 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:

Inspections are available for unoccupied accessory structures (sheds, carports, pool cabanas, both attached and detached garages, decks, etc.).

For select inspection types, platforms such as FaceTime and WhatsApp are available. Please contact your inspector for more information.

Inspections are conducted for partial occupancy permits.

The following protocol must be adhered to for partial occupancy inspections:

1. Contact will need to be made by the site supervisor (site super) to the inspector prior to attendance.
2. 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.
3. 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.
4. The site super is to ensure that any elevator usage is restricted to the inspector and the site super only.
5. 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).
6. 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.
7. 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.
