Building Permits

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 Planning and Building Services 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.

A permit must be obtained before the start of any construction or demolition.


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 assists both property owner 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.

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 by contacting the Planning and Building Services Department by phone at least 48 hours in advance for the following types of inspections:

  • Footings, piers, and slabs on grade, prior to pouring concrete
  • Foundation prior to backfilling
  • Framing / structural
  • Plumbing
  • Heating/ventilation
  • Insulation / vapour barrier
  • Fire separation
  • Exits
  • Fire protection systems
  • Occupancy
  • Final

Private sewage systems, approvals and inspections, must be completed by Niagara Region Public Works Department in accordance with the provisions of the Ontario Building Code.

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.
