The development permit (PA) is mandatory for subdivisions where common equipment is created and for subdivisions located in the following areas:

  • Perimeter of a remarkable heritage site
  • Historical monuments approaches
  • Classified Site or pending filing.

Other subdivisions are subject to advance notification (PNR).

The sale is valid when these 3 characteristics are met. If the parcel acquired proves to be unconstructible, unserviced or demarcated, the buyer may appeal to the judicial judge to request the cancelation of the sale. The use of a lawyer is mandatory.
