BCMS Commencement Notices — Single Residential Units 2017

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.
