Renovation permits in Granby
According to the City of Granby’s information sheet, a building permit is required to build, enlarge or alter (renovate, modify) a main building. Several kinds of work do not need one, for example painting, flooring, electrical work, minor roof repairs, insulating attics and exterior walls, replacing taps or the heating system, or installing a foundation drain; the standards still apply. You apply online.
