The Building Department administers and enforces regulations from the Building Code Act, Building By-Law​, and Swimming Pool Fence By-Law. Building permits and inspections ensure that building projects comply with the property's zoning, along with health, safety, fire protection, accessibility, and conservation standards.

Further information on these changes could be obtained from the Ministry of Municipal Affairs & Housing website, or by contacting the Chief Building Official.
