The Building Code Act requires that permit fees not exceed the anticipated reasonable cost to administer and enforce the Building Code during construction. This ensures the building division operates efficiently and on a cost-recovery basis that does not rely on property taxes for its operation. All costs and expenses, including staff, for plans review and inspections, are obtained through the building permit fees and administration fees charged for services provided.

The purpose of the Ontario Building Code is to protect the health and safety of the public and the occupants of a building. Each and every submission for a building permit is required to be reviewed by the Building Services division to ensure compliance prior to construction starting and to permit the work under the Ontario Building Code Act and its regulations.

Review of all submissions are completed in a timely manner, however, each submission does require a different review process. This involves a review of all applicable laws, including Zoning by-laws, Conservation Authority regulations, other Municipal by-laws, Source Water Protection requirements, and other various acts and regulations within the province of Ontario. The type of project can result in different timelines however the Ontario Building Code does regulate maximum timeframes for complete submissions and complete applications. See the Thames Centre Permit Timelines

Once approval is granted, a permit will be issued for the appropriate work. It then becomes the permit holder and the owner's responsibility to ensure that work continues as per the approved submission and that all inspections are conducted as listed and required on the permit.

Inspections are a mandatory item that is required to ensure that the Ontario Building Code, and other applicable laws, include municipal bylaws, are followed, and construction/work is done safely and correctly. In order to ensure the permit is finalized and completed, all required inspections need to be done.

Prescribed inspections are listed on your building permit under the ‘Stages of Construction Requiring Notice’. These inspections are required to be conducted by the Municipality of Thames Centre Building Department and notice is required to be given to the Building Department prior to each inspection as prescribed by Div.C.1.3.5.1.(2) of the Ontario Building Code.
