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 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.
In most cases, a customer applying for a permit will deal directly with the same Building Inspector who will oversee the permit from the initial application stage through to issuance. The one-on-one approach enables the staff to serve the public in the most efficient manner possible. The Building Division is also responsible for collecting applicable fees, such as Development Charges.
