Once validated by the building control authority, works must commence on site within the 28 day period. In the case of large developments, it is practical to submit a CN for each phase. The number of units scheduled to commence under a specific phase should be recorded in the CN. Number of single residential units commenced — the total number of one off residential units which are associated with the commencement notices submitted for that month.
