Building Permits

A building permit is your approval to begin construction or demolition. By granting a building permit, the City of Timmins has reviewed your plans for any new structure, addition or renovation, and has deemed that the plans have complied with the Ontario Building Code, local zoning by-laws, and any other applicable laws and regulations.

A building permit regulates the type of construction and helps to ensure that building standards are met. The building permit process protects each homeowner’s interest, and protects those in the community by ensuring that any structural changes are legal, safe, and sound.

It is against the law to start construction without a building permit, with many possible results. Costly repairs to ensure Code compliance, removal of work already completed, increased building permit fees, or legal action by the Building Department are some of the consequences of starting construction without a building permit.

Typically, the easiest way to tell if a permit has been issued is to see the building permit placard on the job site. However, if none is visible, you can contact the Building Department and we can verify if a permit has been issued for work that is ongoing.

If no permit has been issued, and the work is still ongoing, one of the building inspectors will investigate to determine whether a building permit is required, and if so, the homeowner will be requested to take out a building permit.
