What a development plan controls
Every council has one. It is written for a set number of years and changed in steps called variations. It covers four things that matter most to a homeowner.
Every piece of land has a zoning, such as residential, town centre or agriculture. The zoning says what can be built there. An extension is usually fine in a residential zone. A new house on land zoned for agriculture usually is not, unless a rural housing rule allows it.
Outside towns and villages, the plan decides who can build a one-off house. Councils often ask for local ties, such as family land or years of living in the area, and may attach an occupancy condition.
The plan uses flood zones. New homes in Flood Zone A or B can face a justification test and a flood risk assessment. The official flood maps are on floodinfo.ie.
The plan lists protected structures and architectural conservation areas. If your home is in one, works that are normally exempt may need permission. You can ask the council for a declaration under section 57.

Extensions, attics and garden rooms
The design rules the council uses when it looks at work on an existing home.
The council supports extending homes as family needs change, but extensions must protect neighbours' sunlight, daylight and privacy and respect the character of the house. Front extensions should not dominate the house, and significant breaks in the building line are resisted. Ground floor rear extensions are judged on length, height, closeness to boundaries and the garden left. First floor rear extensions are only permitted if there is no significant harm to neighbours. First floor side extensions that match the house are generally acceptable.

They should be set back from the eaves, gables and party boundaries, and set down from the ridge so they do not dominate the roof.

It must be able to be absorbed back into the house later. Garden rooms (study, gym, playroom) should be modest in size and cannot provide residential accommodation.

How it affects your project
The plan matters most when a project needs planning permission. Many small jobs are exempt, so check that first.
Many small extensions are exempt, so the plan only counts if you need permission, or your home is protected, or an earlier permission has conditions. When permission is needed, the council checks the design against the plan, for example overlooking, daylight and the garden left. See the Fingal extension rules. Read the extension guide.
Small sheds are often exempt. A garden room used as a separate home, or a large one close to a boundary, can need permission, and then the plan's rules on extra accommodation apply. Read the shed guide.
A new house needs land where the zoning allows it. In the countryside, the rural housing rules decide who can build. Flood zones, access and wastewater also count. Read the new house guide.
Where to read the official plan and map
Always check the council's own copy. Plans are varied from time to time, and the zoning map is the legal record of how your land is zoned.

Common questions about the Fingal development plan
What is the Fingal development plan?
The Fingal Development Plan 2023-2029 (as varied) is the main planning policy document for Fingal County Council. It covers 2023 to 2029 and sets the zoning of land and the local rules the council uses when it decides planning applications.
Where can I see the zoning for my land in Fingal?
Zoning maps are part of the plan. Open the plan on the Fingal County Council website, or use the national viewer at myplan.ie, which shows zoning for councils that have supplied it. Plans can be varied between full reviews, so check the council's own copy for the latest.
Does the Fingal development plan matter if my project is exempt?
If your extension or shed is exempt development, you do not need planning permission, so the council does not assess it against the plan. The plan still matters if your home is a protected structure or in a conservation area, or if an earlier permission has conditions. Our free checker screens your project.
Can I build a house on family land in Fingal?
It depends on the zoning of the site and on the rural housing rules in the plan. Councils usually ask for proof of local ties and attach an occupancy condition. Read the rural housing section of the official plan, and book a pre-planning meeting with the council to test your case.
