Do You Need Planning Permission for a Porch in Ireland?
A porch needs no planning permission in Ireland if it is 2 sq m or less, at least 2m from any public road or footpath, and under 4m high (pitched roof) or 3m (any other roof). Bigger or closer than that needs permission.
Rules have conditions, and the conditions are where projects fail. Answer a few questions about your exact situation and get a plain-English answer with the regulation cited.

Frequently asked questions
How big can a porch be without planning permission?
2 square metres, measured externally, at least 2m back from any public road or footpath. Over 2 sq m -- or closer to the road -- and you need planning permission.
Turns out you need permission?
Start with the pre-submission checklist, estimate costs with the fee calculator, and read the step-by-step application guide. For uncertain cases, a Section 5 Declaration from your council (~€80) gives a formal ruling either way.
