Plan your garage conversion
Four quick taps, and your plan fills in as you answer: the cost in your county, the planning position for your kind of garage and how many weeks it takes. Contact details come last, and only if you want a builder to price it.
An attached garage made into a bedroom in Sligo, mid-range finish: €19,000 to €28,000, including VAT.
How the estimate is worked out
A garage conversion is priced as one job, because the walls, roof and floor slab are already standing: insulating the floor, walls and roof, building up the door opening with a window, wiring, heating, plastering and the finish. The range for your finish is adjusted to your county the same way building rates move between regions of Ireland, VAT at 13.5% included. A shower room, a small kitchen or a steel beam into the house go on top. Totals are rounded to the nearest €1,000. Use it to plan with. It isn't a quote: a builder prices your garage after seeing it.
Planning in Sligo
The rules are national. An attached garage at the side or back converts without permission under Class 1 if it isn't made bigger and fits within the 45 m² it shares with every extension since 1964. In Sligo, section 5 requests and applications go to Sligo County Council: €80 for a declaration, €34 for an application.
Three things can take the exemption away. A condition in the planning permission your house was built under can remove it, and newer estates often have one. On a protected structure, work that would affect its character isn't exempt. And no conversion is exempt if it would obstruct a public right of way or create a traffic hazard.

Do I need planning permission to convert a garage in Sligo?
An attached garage at the side or back of the house can be converted without planning permission under Class 1, as long as the garage isn't made bigger and the conversion, added to every extension built since 1 October 1964, stays within 45 m². A garage at the front, one built into the house facing the road, or a detached garage isn't covered by Class 1: get a section 5 declaration (€80) from the council first, and expect to apply for permission to make a detached garage somewhere to sleep or live. In Sligo, apply to Sligo County Council.
