Why do I need a building permit?
A building permit is a means to regulate developments in the community to meet health, fire, structural and general safety standards to protect individuals and the community as a whole. It is illegal to start work without a permit. Anyone who starts work without a building permit is in contravention of municipal by-law and the Ontario Building Code Act and is; therefore, subject to financial and legal consequences.
