A Disability Access Certificate — or DAC — is a statutory approval that is required for certain types of building work in Ireland. Where a DAC is required, it is good practice to apply for — and ideally obtain — it before construction begins, so that any conditions or Part M issues are known before you're on site. It does not technically have to be granted before you submit your Commencement Notice, but the building cannot be opened, occupied, or operated until the DAC has been granted.

This piece explains what the DAC is, when it is required, how long it takes, and what the process involves. It is a reference piece, not a commentary — the rules are the rules, and the most useful thing I can do here is set them out clearly.

What is a Disability Access Certificate?

A Disability Access Certificate is granted by the Building Control Authority and certifies that the design of a building complies with Part M of the Building Regulations — Access and Use. Part M sets out the requirements for access to and use of buildings by people with disabilities, including wheelchair access, accessible toilet facilities, and related provisions.

The DAC applies to the design stage of a project, not the completed building. It confirms that the design, as submitted, meets the Part M requirements. Compliance with that design during construction is then a matter for the Assigned Certifier and the Building Control Authority inspection process.

When is a DAC required?

A Disability Access Certificate is required for:

New buildings (other than dwellings). This includes commercial premises, office buildings, retail units, industrial buildings, and communal areas of apartment developments.

Material changes of use that bring a building within the scope of Part M. For example, converting a building from commercial to residential apartments, or converting a house into a premises used by the public.

Extensions and material alterations to existing buildings where the work affects compliance with Part M.

A DAC is generally not required for single-family dwellings — houses and standard residential units. However, if a dwelling is being converted to a use that triggers Part M, or if an apartment development includes communal areas, the DAC requirement applies.

If you are unsure whether your project requires a DAC, check with your Building Control Authority or your architect before you proceed. If a DAC is required and not in hand, you will not be able to open, occupy, or operate the building once construction is complete.

When should you apply?

You should apply for your DAC in parallel with your planning application, or as soon as your design is sufficiently developed. The DAC process runs independently of planning — you do not need planning permission before you apply for a DAC, and you do not need a DAC before you apply for planning.

It is good practice to apply for — and ideally obtain — your DAC before construction begins, so that any conditions or Part M issues are known before you're on site. A DAC does not technically have to be granted before you submit your Commencement Notice. However, where a DAC is required, the building cannot be opened, occupied, or operated until the DAC has been granted — so it needs to be in hand well before the building is ready for use.

The standard processing time for a DAC application is eight weeks, though this can vary by local authority and by the complexity of the application. Allow time for this in your programme.

What does the application involve?

A DAC application is submitted to the Building Control Authority. It requires:

A completed application form.

Plans and specifications showing how the design complies with Part M.

The applicable fee — calculated on a per-square-metre basis for most building types.

Your architect or engineer will typically prepare the DAC application as part of their service. If you are unsure whether your consultant has this in hand, ask specifically — it is sometimes overlooked on smaller projects.

Fire Safety Certificates — a related approval

Many projects that require a DAC will also require a Fire Safety Certificate. These are separate applications, assessed separately, but often submitted at the same time.

A Fire Safety Certificate certifies that the design of a building complies with Part B of the Building Regulations — Fire Safety. Like the DAC, it applies to the design rather than the completed building, and it must be in place before the Commencement Notice is submitted.

If your project triggers both a DAC and a Fire Safety Certificate, it is worth ensuring both applications are in progress at the same time to avoid unnecessary delays to your programme.
