It is unlawful to start construction or demolition before you obtain a permit
A building permit is your formal permission to begin construction or demolition. It means that the Chief Building Official has approved plans for new structure, addition or renovation. Approved plans must comply with the Ontario Building Code, local Zoning By-laws, and other applicable laws and regulations.
Building permits regulate types of construction permitted in the community and ensure that building standards are met. The building permit process protects each homeowner's interests, as well as those of the community at large, and provides for the erection of safe structures.
