Grannyflats Dublin — Which Council Covers Your Property and How the 2026 Exemption Applies

Grannyflats Dublin with 2026 planning exemption and all four Dublin councils

One of the most common questions we receive at GrannyFlats.ie — Dublin’s specialist grannyflat builder — since the announcement of the 2026 planning exemption is: “Which council covers my property, and does that affect my grannyflat Dublin?”

The short answer is that the new planning exemption is a national regulation — it applies across all four Dublin councils for qualifying grannyflats Dublin. But the council that covers your property is still important because development levies, registration procedures, and local planning context all differ between Dublin’s four local authorities.

This guide tells you which council covers which Dublin areas, what is specific to each for grannyflats Dublin, and how GrannyFlats.ie manages the council relationship on your behalf across the whole Dublin region.

Does the Planning Exemption Work the Same Across All Dublin Councils?

Yes — the 2026 planning exemption is a national statutory instrument. The core conditions for a grannyflat Dublin (32–45m², detached, single-storey, max 4m height, connected to main house services, full Building Regulations compliance) apply identically across Dublin City Council, Fingal, South Dublin, and DLRCC.

You do not apply for the exemption for your grannyflat Dublin — you build in compliance with the conditions and register the completed dwelling with your council afterward. Read the full conditions at our grannyflats Dublin planning exemption guide and the 45m² exemption detail.


Where the Four Councils Differ for Grannyflats Dublin

Development Levies — Non-Exempt Grannyflats Dublin

For grannyflats Dublin that do not qualify for the exemption (e.g. over 45m²) and require full planning permission, development levies differ between councils:

Council Residential levy rate (approx. 2026) 33m² grannyflat Dublin example
Dublin City Council ~€117/m² ~€3,861
Fingal County Council Varies by zone Confirm at consultation
South Dublin County Council ~€126/m² (2026–2028) ~€4,158
DLRCC Among the highest in Dublin Confirm at consultation

For qualifying planning-exempt grannyflats Dublin under the 2026 exemption, no development levy is payable — making the exemption particularly valuable in DLRCC and South Dublin areas where levies are highest.

Garden Characteristics by Dublin Council Area

Dublin City Council areas: Properties in Dublin 6, 6W, 8, and 12 tend to have smaller rear gardens than suburban properties. Terraced houses limit the exemption’s application. Semi-detached and detached DCC properties often have excellent potential for grannyflats Dublin.

Fingal County Council areas: Fingal has some of the best-suited gardens for grannyflats Dublin in the region. Large suburban semis in Swords, Malahide, Donabate, and Balbriggan typically have 15–25 metre rear gardens with side access. This is where a high proportion of our qualifying Dublin builds are located.

South Dublin County Council areas: Rathfarnham, Templeogue, Lucan, and Tallaght have large stocks of semi-detached homes with generous gardens — excellent for grannyflats Dublin. SDCC areas offer some of the best value-for-money granny flat investment in the Dublin region.

DLRCC areas: DLRCC properties — particularly in Blackrock, Foxrock, Stillorgan, and Killiney — often have the largest gardens in Dublin. The rental premium in DLRCC is also the highest in the region, making grannyflats Dublin in these areas particularly strong investments.
