Lachine: permits and rules
In Lachine, the permit counter offers appointments with the permit team through an online form, but that service cannot be used to file an application; interior and exterior renovation applications are filed online. In certain sectors, construction and exterior changes require PIIA (site planning and architectural integration) approval (in Old Lachine this also applies to a sign or a satellite dish), and throughout the borough, work on residential buildings of 4 or more units is subject to it.
