105. A person may, without the authorization of the commission, alienate, subdivide or use for a purpose other than agriculture a lot which, after the date on which the provisions of this act requiring the authorization of the commission have been made applicable to it, is or becomes adjacent to a public road along which public water and sanitary sewer services are or are to be installed under a municipal by-law passed before that date and approved in accordance with the law.
The right recognized in the first paragraph exists in respect of an area not exceeding a half-hectare where the lot is to be used for residential purposes, and not exceeding one hectare or five times the area occupied by the buildings, whichever is less, where the lot is to be used for commercial, industrial or institutional purposes.
This right does not extend, however, to any part of the lot situated more than 60 metres from the right of way of a public road in the case of a residential use, or more than 120 metres from that right of way in the case of a commercial, industrial or institutional use.
