When building work needs to commence and be completed

The Regulations specify commencement and completion dates for building work associated with a building permit. If works have not commenced or completed within these times, then the building permit will lapse.

Required commencement date

Required completion date

Houses and outbuildings

Within 12 months of the date of issue of the building permit

Within 24 months of the date of issue of the building permit

Swimming pools and associated barriers or fences

Within six months of commencement of the work (except if carried out in conjunction with other work)

Re-erection of houses and out buildings

Within six months of the date of the issue of the building permit

Completed within 12 months of the date of issue of the building permit

All other building work

Within 12 months of the date of issue of the building permit

Within 36 months of the date of issue of the building permit

Requesting an extension

If you can’t commence or complete the building work in time, you can ask your building surveyor for an extension. You must do this before the relevant date passes. The building surveyor may grant an extension if the extent of the building work warrants it.

If they refuse to grant an extension, you may appeal the decision through the Building Appeals Board.
