Building Permits

A building permit considers how a structure is built.

It allows the construction or demolition of structures contingent on meeting the requirements of the Alberta Building Code. It gives authorization to erect, demolish, relocate, alter or repair a structure, or change the use or occupancy of a space within Medicine Hat. Building permit applications are reviewed for compliance with the National Building Code - Alberta Edition by a Safety Codes Officer to ensure that our built environment is safe.
