BCMS total residential units commenced Mar 2014 to Sept 2016

This data is collected through the BCMS, Building Control Management System, which is operated by the LGMA. It is collated and issued to the DHLHG on a monthly basis. Each commencement notice details new residential units which will be constructed in that month.
Due to the nature of the commencement notice process, there may be slight changes to previously published data due to retrospective processing of notices.
Up until August 2015, Local Authorities or builders carrying out work on behalf of a local authority were not required to submit Commencement Notices provided that the work in being carried out in that local authority's administrative area. After 1/9/2015, Local Authority units are included in the commencement notice data.
The Dublin local authorities area includes Dun Laoghaire, Fingal, South Dublin and Dublin City. The Greater Dublin Area includes all four Dublin local authorities and Kildare, Meath and Wicklow.
Definition of the variables above:
Number of residential units commenced - the total number of residential units which are associated with the valid commencement notices reported on for that month. One off units are included within this figure.
Differences to the previously collected between 2004 and early 2014:
Methodological difference: The previous data was collated from 37 Building Control Areas by the DHLHG. This data is drawn from a database of information held by the LGMA from data directly inputted by developers/builders online or by the local authority.
Definition difference: The 2004-early 2014 data used the date of receipt of the commencement notice i.e. a notice received in March could relate to a project commencing in April yet would be reported in the March dataset. This dataset from the BCMS uses the date of commencement of the project i.e. a notice received in February with a commencement date of March will be reported in the March dataset. The most current data is published on these sheets. Previously published data may be subject to revision. Any change from the originally published data will be highlighted by a comment on the cell in question. These comments will be maintained for at least a year after the date of the value change.
