    Know What’s Being Built Near You: How Commencement Notice Alerts Keep You Informed

    Published in The MapAlerter Blog, Oct 29th 2025

    Ever wonder when construction is about to start in your neighborhood? In Ireland, this is tracked through Commencement Notices, a formal step after planning permission is granted. MapAlerter makes it easy for you to stay informed about upcoming construction, possible road disruptions, and changes happening near your home.

    What Is a Commencement Notice?

    A Commencement Notice (CN) is a legal notification submitted by a builder or developer to the local authority before starting construction. Think of it as the official “we’re starting work” signal. It differs from planning permission, which tells a developer what they can build. The CN confirms that construction will comply with building regulations and safety standards. Some projects may also use a 7-Day Notice if certain certificates, like Fire Safety Certificates, are still pending. The notice is recorded in the Building Control Management System (BCMS), maintained by the National Building Control & Market Surveillance Office (NBCO).

    Why Commencement Notices Matter to Residents?

    Commencement Notices give you a clear view of what’s happening in your community:

    • Construction Start Dates: Know exactly when a project begins.
    • Estimated Completion Dates: See when works are expected to finish.
    • Community Impact: Plan for potential roadworks, scaffolding, or noise.
    • Transparency: Access publicly available data to stay informed about local developments.

    What Projects Require a Commencement Notice?

    Most major building works need a CN, including:

    • New buildings or homes
    • Extensions or renovations
    • Material changes of use (like converting a house into offices)
    • Certain commercial alterations (shops, offices, industrial buildings)

    Small projects, minor works, or those exempt from building regulations may not require a CN.

    How MapAlerter Helps You Stay Informed?

    MapAlerter transforms official CN data into easy-to-use alerts and interactive maps:

    • Active Construction Only: Maps show projects that have started and are still in progress — expired projects are automatically removed.
    • Accurate Dates: Alerts highlight start dates and estimated completion, keeping information reliable.
    • Neighborhood Alerts: Receive updates about construction near your home, so you can plan ahead.

    Community Awareness: Know when developments could affect traffic, noise, or public spaces.
