Addition Permit

Ottawa Additions Permit

If you plan to build a new structure, add an addition, or alter an existing building in Ottawa, you’ll need a building permit if the area is over 10 square metres (about 108 square feet). Examples of additions that require a permit include sunrooms, solariums, attached garages, porches, and one or two-story additions.

The Ontario Building Code sets out the minimum requirements for elements like framing and foundation. You can access the code on the Ontario Ministry of Municipal Affairs and Housing website.

Ottawa Building Permit Application

To apply for a building permit in Ottawa, you’ll need to provide the following:

  • Completed Application for a Permit to Construct or Demolish

Required Inspections

Inspections are required at key stages throughout the building construction process to ensure compliance with the Ontario Building Code. The permit plans and specifications must be on site and made available to the Building Inspector during the inspection. To ensure availability of a Building Inspector, inspections should be booked 48 hours in advance.

Failure to perform the appropriate inspections may result in orders to uncover and expose the work for inspection or other corrective actions, which can cause delays and increase costs. Required inspections include:

  • Sewer lateral inspection
  • Excavation inspection
  • Plumbing inspection
  • Foundation inspection
  • Plumbing rough-in inspection
  • Framing and mechanical rough-in inspection
  • Insulation and vapour barrier inspection
  • Plumbing final inspection
  • Occupancy inspection
  • Final inspection

Applicable Fees

  • Two sets of plans that are legible and drawn to a conventional scale, including a checklist and sample plan (available online)
  • Truss layout as supplied by the manufacturer, if required for complex pre-engineered roof trusses
