What these terms mean
- Commencement notice
- A legal notification to a Building Control Authority that construction work covered by the Building Regulations is about to begin. Source
- Why this is not planning permissions or completions
- Permissions measure intent to seek approval; commencements measure intent to build (this dataset); completions measure homes actually finished. The three move at different times, sometimes years apart.
Before you use these figures
- Not available for this area: No figure is published at or above Roscommon.
- A commencement notice precedes building, it is not a completion: A commencement notice is a legal notification that construction work is about to begin, collected via the Building Control Management System (BCMS). It measures intent to start building, not homes finished -- see the completions dataset for that. The gap between a commencement and a completion can run to months or years.
- Small authorities swing on single developments: In a smaller local authority a single large development's notice can swing a month's total sharply. Percentage changes are large and ordinary at this level and describe building scheduling more than housing policy.
- One-off units are included in the residential-units headline: The headline 'residential units commenced' figure already includes one-off (single, self-build) units -- they are not a separate count to add on top.
