Building Permits


What is a Building Permit? 

A building permit gives you the legal authorization to start construction of a building project in accordance with approved drawings and specifications.  Building permits are issued by the Building Services division and are reviewed for compliance with the Ontario Building Code, the applicable municipal zoning by-law and other applicable provincial and municipal regulations. building permits are necessary to ensure that zoning requirements, fire and structural safety standards, and other building standards are met.

When are Building or Demolition Permits required?

In general, a building permit is required to erect, install, extend, alter, or repair a building. A demolition permit is required to demolish all or part of a building. It is the homeowner's responsibility to ensure, when necessary, that a building permit is obtained before beginning any construction or demolition.

If you are unsure if a permit is required, please review the details of the work with our customer service representatives prior to construction or demolition.

Building Inspections (not associated with a permit)

  • Fire damaged/vacant buildings
  • An unsafe condition of a building
  • Construction without a building permit

Inspections (where a permit has been issued)  

The Building Services division carries out inspections in conjunction with building permits and also responds to customer requests to determine if a permit is required. The staff assist both homeowner and contractor to complete their projects in accordance with building code regulations and applicable zoning requirements. When voluntary compliance is not forthcoming, enforcement is initiated.

The inspectors work closely with other regulatory bodies such as Fire Prevention, health department, engineering department, Region of Niagara, Niagara Peninsula Conservation Authority, Niagara Escarpment Commission, Ministry of Transportation, etc. to ensure that all applicable regulations are adhered to.

Upon obtaining a building permit, a contractor or property owner is required to arrange inspections during the various phases of construction. The required inspections are listed on the permit. Appointments can be made with the Building Inspector by phone for the following types of inspections:

  • Footings
  • Foundation drains
  • Framing/structural
  • Plumbing
  • Heating/ventilation
  • Insulation/vapour barrier
  • Fire separation
  • Exits
  • Fire protection systems
  • Occupancy
  • Final

If any deviations from the by-law are observed, appropriate action will be taken by the inspection staff to gain compliance to any by-laws under their jurisdiction.


Permits may require additional fees and are reviewed based on an individual permit basis.

Additional fees may include, but are not limited to, site servicing, drainage/grading, sidewalk damage deposit, curb cuts, curb infills, construction, water, etc.
