How do I apply for planning permission in NI?

So you're thinking about building something in Northern Ireland? Right, well the whole planning thing is run by local councils, with the Department for Infrastructure kinda overseeing everything. Whether you want to slap on an extension, build a whole new house, or change how you're using a building, you're gonna need to go through the proper channels. That means submitting a proper application to your local council's planning office. You'll need detailed plans, an online or paper form, some cash for the fee, and then you wait through a consultation period. Get it right from the start or you'll be stuck in delays—or worse, get told no.

What is the first step to apply for planning permission in NI?

First things first—do you actually need permission? In NI, some stuff counts as "permitted development" and doesn't need an application. Small rear extensions, porches, boundary walls—they might fall into this category, but there are strict limits. Honestly, you should dig out the DfI's Permitted Development guide or just ring your local council's planning department. A quick pre-application chat saves headaches. If you do need permission, decide whether you're going for a full application or just an outline one (handy for bigger projects).

How do I submit the planning application form?

You've got two options: apply online through the NI Planning Portal at www.planningni.gov.uk, or fill out a paper form and send it to your council. The main form is called "Planning Application Form" (Form 1). You'll need to include:

• The completed form with your name, address, and exactly where the site is.
• A location plan at 1:1250 or 1:2500 scale, with the site boundary marked in red.
• A site plan (1:500 or 1:200) showing what's there now and what you want to build.
• Drawings of the proposed development—floor plans, elevations, sections, the works.
• A Design and Access Statement (for most applications, unless it's really minor).
• The right fee, which depends on what you're building and how big it is.

All plans need to be properly scaled and clearly labelled. You can hire a planning consultant or architect to sort this out, but honestly, you don't have to.

What documents and fees are required?

Fees aren't one-size-fits-all. A single dwelling extension? That's £220. A whole new house? £440 (as of 2023). Always check the latest fee schedule on the NI Planning Portal—things change.

How long does the planning process take in NI?

Once you've submitted, the council has 5 working days to validate your application. After that, the consultation period kicks in: 21 days for neighbour notifications, 28 days for public ads if needed. The council's supposed to decide within 8 weeks for minor stuff, 12 weeks for major projects. In reality, simple applications often get a decision in 6-8 weeks. But complex ones? They can drag on for 4-6 months. Delays happen when they ask for more info—like environmental impact assessments—which is a pain.

What happens after I submit the application?

Your local council will:

• Check if everything's filled in properly.
• Tell your neighbours and stick up a site notice.
• Consult statutory bodies like DfI Roads, NIEA, Rivers Agency.
• Measure your proposal against the local development plan and planning policies.
• Give you a decision—either grant permission or refuse it.

If you get the green light, there might be conditions attached. Time limits, materials specs, that sort of thing. If it's a refusal, you've got 6 months to appeal to the Planning Appeals Commission (PAC).
