The Complete Guide to Building Inspection Request in Toronto

 Inspection Request

Building inspections play a vital role in the construction process, guaranteeing adherence to the Ontario Building Code and pertinent safety regulations. This comprehensive guide offers insight into inspections in Toronto, outlining the steps to initiate an inspection request, offering advice for a seamless inspection experience, and presenting additional resources for deeper understanding of the inspection system.

What are Building Inspections?

Building inspections ensure that construction, renovation, or demolition activities on a property align with approved plans, necessary permits, and building codes. These inspections are initiated through an inspection request.

Inspections aim to ensure the health, safety, and welfare of building occupants and the public by checking that:

  • Structural integrity is sound
  • Fire safety standards are met
  • Plumbing, electrical, ventilation and HVAC systems are properly installed and functioning
  • Accessibility requirements are fulfilled
  • Construction materials and techniques meet standards
  • Projects adhere to zoning rules and approved permits

Building inspectors visually inspect the workmanship and materials at various stages during the construction process. They check for any code violations, deficiencies, or safety issues that must be corrected before work can proceed.

Inspections are an important quality assurance step to confirm that work meets municipal requirements as outlined in the Ontario Building Code.

Overview of Building Inspections in Toronto

The City of Toronto's Building Division enforces compliance with the Ontario Building Code through issuing building permits and conducting mandatory inspections for construction projects.

Toronto Building sends qualified inspectors to verify that work underway or completed at a property meets the minimum standards set out in the building code and applicable laws. Inspections apply to structural work, plumbing, electrical systems, heating and ventilation, fire safety equipment, and occupational readiness of a building.

Common types of building inspections include:

Inspectors check that materials and installation methods meet code requirements. They look for issues like:

  • Improper construction techniques
  • Substandard materials being used
  • Deviations from approved plans
  • Defective workmanship
  • Safety hazards
  • Code violations

Toronto Building aims to enforce compliance equally across all construction projects in the city, whether for a high-rise building or a home renovation. Inspections ensure that every project meets the minimum standards set out in the Ontario Building Code.

When are Inspection Required in Toronto?

The City of Toronto mandates inspections at certain key stages during the construction process. The Building Code specifies the minimum mandatory inspections, while some additional inspections may be required for certain types of projects.

In general, the City of Toronto requires inspections at the following stages:

  • After demolition or removal of load-bearing partitions - To inspect safety measures and structural impacts
  • Foundation stage - To check foundation walls, footing forms, dampproofing, perimeter drainage
  • Structural framing and ductwork - To verify framing, fireblocking, bracing, and HVAC ducts
  • Rough-in of electrical, plumbing, drainage, ventilation - To check rough-in systems prior to concealment
  • Insulation and vapor barrier installation - To confirm insulation values and prevent moisture issues
  • Fire protection and alarms - To test functionality of fire safety systems
  • Occupancy inspection - Done prior to inhabiting building to check life and fire safety

See the City's construction requirements guidelines for full details on mandatory inspections at each phase.

Some specialized projects may also require additional inspections related to the building use and type of construction. For example, townhouse projects require separate framing inspections for each unit. Industrial occupancies may require inspection of high-load storage racks.

The required inspections should be outlined in the approved building permit plans. The permit holder must understand and schedule appropriate inspections throughout the project.

Building Inspection Request in Toronto

request for inspection

When mandatory inspection stages are completed during your construction project, you need to request an inspection from the City building department. Here are the options for requesting inspections in Toronto:

Online Inspection Request

The fastest and most convenient way to request an inspection is by using the City of Toronto's online inspection request form.

To request an inspection online, you will need to provide:

  • Building permit number

  • Online requests must be submitted before 4 pm on weekdays for the next day
  • Inspections are conducted Monday to Friday, between 8 am and 4 pm
  • No inspections are performed on weekends or statutory holidays
  • Provide accurate project address and permit number
  • Onsite contact must be present at the time of inspection
  • Late requests may not be accommodated same/next day

Bear these key points in mind when scheduling inspections to avoid delays.

Preparing for a Smooth Inspection Process

Proper planning and preparation will help facilitate an efficient inspection process. Here are some key tips for a smooth inspection experience:

Review previous inspection reports

  • Check the last inspection record and address any failed or outstanding issues. This information is available through the City's online permit lookup.
  • Previous deficiencies must be corrected before scheduling the next inspection.

Ensure approved plans are onsite

  • Have the approved building plans and permits available onsite for the inspector to review.
  • Plans must match the current state of construction.

Prepare the inspection area

  • Make sure the area requiring inspection is accessible, clear of obstructions, and safe for the inspector to enter and evaluate.
  • Inspection sites should be clean and orderly. Provide any necessary protective equipment.

Have appropriate personnel onsite

  • The permit holder or authorized personnel must be onsite to meet the inspector.
  • Employees knowledgeable of the project should be available to answer questions.

Understand the scope

  • Know which specific areas, systems, or components are to be inspected. Focus on making those accessible.
  • Be prepared to show completed work and any areas that will be concealed by finishes.

Ask questions

  • Don't hesitate to ask inspectors questions about code compliance as they evaluate the work. Their job is to assess the code.
  • Make sure you understand any next steps, corrections needed, or documents required.

Thorough preparation and cooperation will demonstrate you value the inspector's time and help the inspection process go smoothly.

What Happens During the Inspection?

When the requested inspection date arrives, the assigned inspector will come to the property to conduct the onsite inspection.

The inspector will visually assess the work completed up to that stage to determine compliance with approved plans and the Ontario Building Code.

Here is an overview of what typically happens during an onsite inspection:

  • Inspector arrives and verifies permit information
  • Reviews approved plans and documents
  • Inspects the completed work relevant to the type of inspection
  • Checks for quality of workmanship and materials
  • Identifies any code violations, deficiencies, or safety issues
  • Provides feedback to those onsite and outlines any corrections needed
  • Answers questions related to code compliance

Specifics will vary depending on the stage and type of inspection. The inspector examines all accessible work relevant to that phase.

For example, during a framing inspection, the inspector will look for:

  • Consistent measurements with plans
  • Proper material grades and installation
  • Adequate structural connections
  • Fire blocking between floors and studs
  • Smoke alarms and fire separations

Inspectors may conduct additional checks beyond the work called for in that inspection based on site observations. Safety issues must always be addressed promptly.

Listen carefully to all feedback provided by the inspector and take notes if needed. Make sure any unclear aspects are asked about before they leave. Having a thorough understanding of any deficiencies will prevent delays going forward.

Possible Inspection Outcomes

There are three potential outcomes after the onsite inspection is complete:

1. Pass

The work passes inspection and is signed off. Construction may proceed to the next stage.

2. Conditional approval

Minor non-structural deficiencies were identified that do not require re-inspection after correction. Photos or documentation may be requested.

3. Failed/Further inspection required

Significant deficiencies requiring re-inspection were found. Do not conceal any work until the re-inspection passes.

Failed inspections are not unusual, as long as the issues get addressed before continuing. 

Common reasons for inspection failure include:

  • Deviations from approved plans
  • Improper materials or installation
  • Omitted structural components
  • Code violations in electrical, plumbing, HVAC
  • Life safety issues like smoke alarms

Make sure you understand the scope of corrections required. Ask when re-inspection should be scheduled. Address all deficiencies before calling for re-inspection or covering any work.

After the Building Inspection

Once the inspection is complete, the results will be updated in the City's permit records, usually within 1-2 business days.

If deficiencies were noted requiring re-inspection:

  • Review the inspection report and scope of corrections needed
  • Obtain contractor quotes to complete repairs as needed
  • Address all outstanding issues and schedule a re-inspection when ready

For inspections marked as conditional approval or passed:

  • Confirm if any follow-up documentation is required
  • Proceed to enclose the completed work and move to the next stage

Do not conceal any installations until the relevant inspection has passed. Covering unapproved work may require removing finishes for proper inspection. Contact the inspector or City with any questions on the inspection results. Save all inspection reports for your records. Once all mandatory inspections have passed for the stage of work completed, proceed to schedule a final inspection. The building may then be approved for occupancy pending any final sign-offs.

Denied Occupancy and Ordered Repairs

If the final inspection reveals substantial violations posing an immediate hazard, the inspector may deny occupancy and order repairs under Section 15 of the Building Code Act. This means the project cannot proceed and the space cannot be inhabited until significant code violations are corrected and re-inspected.

If a Section 15 order is issued, the construction team must:

  • Immediately stop work
  • Prevent occupancy of the space
  • Determine the full scope of mandatory repairs
  • Complete all repairs ordered
  • Call for re-inspection once repairs are done
  • Ensure the inspector approves the resumed occupancy

Section 15 orders are rarely issued but may occur if fire safety, structural stability, or other serious violations are detected.

Using an Inspection Service in Toronto

For most residential projects like basement finishes or renovations, hiring a private inspection service is not required in Toronto. The mandatory inspections will be conducted by City building inspectors. However, for some major construction projects, private building inspectors licensed by the Ministry of Municipal Affairs and Housing may be engaged to conduct additional inspections for enhanced due diligence.

This is not mandatory but can provide peace of mind. When hiring a private inspection firm like InspecTech Inspection Services or National Home Inspector, inform them of the project scope and stages requiring third-party inspection. Their qualified inspectors can conduct periodic reviews and furnish inspection reports. All deficiency repairs ordered by a private inspector should still be verified by the City building inspector during the next scheduled inspection.

Tips for an Efficient Inspection Process

Here are some additional tips for a smooth inspection process:

  • Thoroughly review the approved permit drawings and documents
  • Address any previous deficiencies early
  • Keep the site clean and make areas easily accessible
  • Monitor weather forecasts and reschedule if necessary
  • Be flexible with scheduling as inspectors have full schedules
  • Keep key staff onsite who are knowledgeable about the project
  • Ask questions and take notes for a clear understanding
  • Maintain respectful communication and cooperation

Following proper protocols will demonstrate you value the inspector's time and aim to operate safely and legally. This mutual understanding will help move each stage of the project forward.

Requesting Inspections for a Renovation Project

If you are renovating an existing home or apartment unit, building inspections are still required for any structural changes or major system upgrades. Here are some tips for smooth inspections during a renovation project:

Obtain required permit(s)

Apply for building, electrical, plumbing, or other permits required for the scope of work. The permit submission will outline the mandatory inspections.

Schedule inspectors efficiently

Group-related work together where possible to minimize repeat visits. For example, schedule electrical rough-in and insulation inspection together.

Keep areas clear

Since workspaces are smaller in renovations, maximize access and visibility for inspectors. Remove furnishings or stored items from around work areas.

Communicate access instructions

Provide entry and access instructions to inspectors for buildings with security doors or concierges. Meet them to escort if needed.

Monitor progress

Watch for early signs of schedule/budget overruns. Delays in getting work inspected and approved can impact timelines significantly.

Check final approvals

Before finishing walls and floors, confirm electrical, plumbing, and mechanical got approved. Review outstanding items.

Prepare for a final occupancy inspection

Make a punch list for deficiencies and confirm all major systems are complete with the code.

Ask about documentation

Find out what certificates or letters need furnishing to the City after passing the final inspection.

Thorough planning and project management will help inspections go smoothly during your renovation.

Inspections for New Home Construction

For new residential builds, a series of mandatory inspections will be required through each stage of construction:

  • Excavation/Foundation - Footings, foundation walls, dampproofing, drainage
  • Backfill - Foundation drainage, waterproofing, perimeter insulation
  • Structural Framing - Floors, walls, roof, fire blocking, sheathing
  • Plumbing Rough-in - Piping, vents, drains, water system
  • HVAC Rough-in - Furnaces, ductwork, vents, chimneys
  • Electrical Rough-in - Wiring, panels, devices, grounding
  • Insulation/Vapour Barrier - Proper insulation and air barrier installation
  • Fire Separations - Fire-rated assemblies between units
  • Occupancy - Final safety review for occupancy permit

New builds require coordination across trades to move through successive stages methodically. Keep in contact with the City inspector throughout the build.

Owner/Builder Inspections

Owner-builders doing their own construction work still require all mandatory inspections. When requesting:

  • Disclose you are the owner and builder
  • Provide appropriate contact information
  • Be available onsite yourself for all inspections
  • Ask questions and take notes for your records
  • Follow inspector guidance to avoid needing revisions

Ensure you fully understand the scope of any failed inspections and corrections ordered. Re-reads or extra visits add time and cost.

Inspections for Commercial Projects

Commercial construction entails specialized inspections like:

  • High-pile storage
  • Fire alarm and suppression systems
  • Accessibility features
  • Assembly occupancies
  • Hazardous processes/equipment
  • Fire separations and exits

Work through each stage methodically with your permit plans. Bring qualified personnel such as engineers or architects to inspections as needed.

Swimming Pool Inspections

For in-ground pool installations, installers and homeowners must call for multiple inspections:

  • Excavation - Before placing reinforcing steel check the slope and depths
  • Electrical bonding - Bonding points and pool wiring
  • Plumbing - Catch basins, return lines, skimmer housing
  • Final inspection - Fencing, gates, barriers, and safety equipment

Check for proper fence height, gate latches, and other safety measures before finalizing the pool.

Understand the inspection requirements at each stage. Pay close attention to provide life safety and prevent drowning risks.

Tips for Renovating Older Homes

Renovating older properties presents additional inspection considerations:

  • Research original construction permits and inspect records if available
  • Look for the presence of hazardous materials like asbestos and lead
  • Watch for structural issues concealed by finishes
  • Test electrical and plumbing systems thoroughly before altering
  • Update all smoke/CO alarms and firestops
