The Building Control Regulations apply to new buildings, extensions, material alterations and changes of use of buildings. They promote observance of the Building Regulations by supplementing powers of inspection and enforcement given to Building Control Authorities.
The Building Control Regulations regulate:
1. Commencement Notices and 7 Day Notices
2. Fire Safety Certificates, Revised Fire Safety Certificates and Regularisation Certificates
3. Disability Access Certificates and Revised Disability Access Certificates
4. Maintenance of Registers
5. Fees
6. Statutory registration of building control activity
Failure to submit a Commencement Notice is an offence and will have serious consequences which cannot be regularised at a later date. You may have difficulties in selling your property if you cannot prove that the statutory requirements relevant to the property have been met.

Regarding the situation where somebody resident outside the jurisdiction of the Republic of Ireland wishes to sign a Statutory Declaration:
When a Statutory Declaration is being witnessed outside the jurisdiction it should be signed in the presence of a Notary Public. A notary public is an internationally accepted accreditation.

This Statutory Declaration is a legal sworn document. You are swearing that you have read, understand and are aware of the undertaking being made in this Statutory Declaration.

You should seek separate legal advice prior to signing the Statutory Declaration in the presence of (a) a notary public, (b) a commissioner for oaths, (c) a peace commissioner, or (d) a person authorised by law to take and receive statutory declarations as (a), (b), (c) or (d) cannot give advice on the contents, their sole purpose being to witness the signature.

•A Commencement Notice is a notification to a Building Control Authority that a person intends to carry out either works or a Material Change of Use to which the Building Regulations apply. The notice must be given to the authority not more than 28 days and not less than 14 days before the commencement of works or the change of use. Once validated by the building control authority, works must commence on site within the 28 day period.
•If the works do not start within 28 days of the date of lodgement of the Commencement Notice, you must submit a new Commencement Notice prior to the commencement of any works taking place.
Section 6 (k) of the Building Control Acts 1990-2014 require the giving of notice to building control authorities of the erection of such buildings, or classes of buildings, or the carrying out of such works, or classes of works, as may be specified in the regulations. The Regulations provide for four Commencement Notice (CN) types:
i. Commencement Notice With Compliance Documentation
ii. Commencement Notice with Opt Out Declaration
iii. Commencement Notice Without Compliance Documentation
iv. 7 Day Notice which includes for
(a)FSC
(b)Declaration
NOTE: IF IN DOUBT, CONTACT YOUR LOCAL BUILDING CONTROL AUTHORITY
A 7 day notice is similar to a Commencement Notice and may be used for works, which require a Fire Safety Certificate, when the works need to start before the Certificate is granted. It must be accompanied by a valid Fire Safety Certificate application and a Statutory Declaration. After the 1st March 2014, the additional requirements which apply to Commencement Notices will also apply to 7 Day Notices. The fee for a 7-Day Notice is €250 or €5.80 per square metre of applicable floor area (whichever is the greater).
Commencement Notices are required for the following:
- the erection of a building;
- a material alteration or extension of a building, or material change of use of a building;
- works in connection with the material alteration (excluding minor works) of a shop, office or industrial building.
Note: a commencement notice may be required in certain circumstances where a planning permission is not required e.g. for extension with a floor area not exceeding 25sqm or certain material alterations. Contact your local Building Control Officer for further clarification.
A Commencement Notice is not required:
- for works or a change of use which are exempted development under the Planning Acts, and for which a Fire Safety Certificate is not required;
- or where a 7 Day Notice has been submitted.
The fee for a Commencement Notice (Fifth Schedule Part A of the Building Control Regulations) is €30, or where the Commencement Notice relates to multiple buildings & neither parts III of the Building Control Regulations apply, €30 in respect of each building.
Additional charges will be imposed by the Building Control Authority for commencement notices which are not submitted online via the Building Control Management System.
Defined in the Building Control Act Interpretation Section 1.“building” includes part of a building and any class or classes of structure which are prescribed by the Minister to be a building for the purposes of this Act; For clarity each part of a building that is considered a dwelling (being a house or flat) can be considered a building in it's own right. As Parts III of the Building Control Regulations apply to flats, a building that contains flats, that is one subdivided horizontally, would be subject to a €30 fee. In other circumstance where the building is subdivided vertically the dwelling can be considered a house and houses are not subject to Parts III. In such case payment of €30 for each dwelling in the building is applicable. The maximum fee (Part B) is €3,800.
The fees for a seven day notice are €250 or €5.80/m2 of floor area, whichever is the greatest (€130 or €1.60/m2 for agricultural building) Submission of a 7 day notice must be accompanied by a valid Fire Safety Certificate application
The maximum fee (Fifth Schedule Part B) is €25,000
