Inspection

Inspection Steps in Wooden Buildings in Canada:
1) Footing Stage:
Preparation for Inspection:
- Ensure the excavation site is clear and the footing forms are properly laid out with the correct placement of rebar as per engineering specifications.
- The inspection should be scheduled before pouring the concrete.
During the Inspection:
- The inspector verifies the size, depth, and placement of footings relative to the property lines and building layout.
- The footing design, including rebar arrangement, must comply with the drawings approved by the engineer.
2) Foundation Wall:
Before Concreting:
- Confirm the required inspection of reinforcement and formwork before concrete placement.
- Provide safe access and the required documentation. Photographs are supplementary unless the authority explicitly accepts them instead of an on-site inspection.
Inspection Considerations:
- The inspector will check for proper rebar positioning, size, and quantity to ensure it meets structural requirements.
3) Prebackfill:
Preparation for Inspection:
- Apply waterproofing and dampproofing membrane to the foundation walls.
- Install weeping tiles or foundation drains and cover with gravel to ensure proper drainage.
During the Inspection:
- The inspector checks the waterproofing, drainage, and damp-proofing for integrity and proper installation.
- Additional checks may be performed for foundation depth, setbacks, and if the basement height is a concern, ensuring it is not misclassified as the first floor due to excessive height.

4) Framing, Plumbing, and HVAC:
Concurrent Inspections:
- Confirm the inspection sequence with the local building department; framing, plumbing, and HVAC inspections may be separate.
- Complete the work required for each inspection and keep it accessible until permission to cover it is given.
Plumbing and HVAC:
- The plumbing rough-in, which includes the installation of drain and water pipes, is inspected for proper slopes and support.
- HVAC ductwork and equipment should be installed and ready for inspection.
5) Electrical Rough-In:
By Certified Electrician:
- In Ontario, arrange electrical notifications and inspections through the Electrical Safety Authority (ESA), as applicable. Other jurisdictions have their own authorities.
- The responsible electrical contractor must confirm the required inspection stages before wiring is concealed.
6) Insulation:
Preparation for Inspection:
- Insulate the building according to the local code requirements.
- The vapor barrier must be installed properly to avoid any possible moisture issues.
7) Fire Separation:
If Applicable:
- Depending on the proximity to adjacent buildings, a fire separation inspection may be necessary.
- This involves verifying fire-rated construction between units or properties.
Additional Steps:
Gas Inspection:
- Have gas work performed and documented by appropriately qualified contractors. Confirm inspection and activation requirements with the responsible regulator and gas utility; a utility visit does not replace every required inspection.
Drainage:
- Have the in-floor drainage inspected before it’s covered, ensuring the slopes are correct directing water appropriately outside.
Fire Alarm and Carbon Monoxide Detectors:
- Ensure smoke alarms and carbon monoxide detectors are in place and functional.
8) Final Inspection:
Completion Checks:
- Verify required guards, handrails, plumbing fixtures, access points, and protective devices against the approved design.
- Confirm required gas installation records, equipment commissioning, and heating-system design documentation.
Occupancy Permit:
- Obtain the required occupancy authorization from the local authority before occupying the building. Conditions and documentation vary by jurisdiction; completing an inspection does not automatically authorize occupancy.
General Tips:
Documentation:
- Keep engineering reports, permits, and photos ready for each stage of inspection.
Coordination:
- Schedule inspections well in advance and ensure the site is prepared and accessible for the inspector.
Compliance:
- Follow all recommendations by inspectors and correct any issues immediately to avoid delays in receiving clearance to proceed.
Shoring (if applicable):
- If shoring is required for excavation, an inspection will need to take place before this stage begins.
This is a general inspection overview, not a complete or universal sequence. Confirm required stages, documentation, and permission to proceed with the authorities responsible for the project.
