Frequently asked questions

It depends on where you are. In industrial estates or business parks, most standard signage is "Exempted Development" provided it meets specific size limits (usually under 5 square meters total and not higher than 4 meters off the ground). However, if your building is a Protected Structure or in an Architectural Conservation Area (ACA), you almost certainly need permission. Visit dublinsigns.ie for more info.

Generally, you are free to do what you like inside your own building. However, there are two important exceptions. First, if the sign is illuminated and clearly visible from the street (like a screen in a window), it is treated as a window display and must cover less than 25% of the glass area. Second, if your building is a Protected Structure, you generally cannot drill into historic features (like decorative plasterwork or original panelling) without permission.

An Architectural Conservation Area (ACA) is a designated zone like Grafton Street, Capel Street, or the historic centres of towns like Kilkenny and Galway. In these areas, the rules are strict: plastic signs, internal illumination, and vinyl stick-ons are generally banned. You must use high-quality materials like painted timber, metal, or stone.

In a modern retail park, yes. But in a city centre or ACA, the Council will likely refuse a plastic lightbox. The preferred option is "Halo Illumination" (where the light glows softly behind metal letters) or an external trough light painted to match your fascia. These look better and are more likely to be approved.

Yes, but strictly within limits. Under Class 2 Exemptions, an illuminated sign inside a window must not cover more than 25% of the glass area. If you block the whole window with a video wall, it requires planning permission and may be refused for being a distraction to drivers.

No. We are design and manufacturing specialists, not Planning Consultants. We can provide the technical drawings and specs your architect needs for the application, but we do not act as your legal agent with the Council.

We manage a dedicated resource at DublinSigns.ie. It breaks down the specific regulations, allowed materials, and design guides for Dublin City Council. It is a great place to start if you are unsure about what is allowed on your street.
