What is a material change of use in planning law?

A material change of use is a change in how a property is used that raises new planning considerations, such as traffic, noise, or residential amenity, even if no building work happens. Material changes of use are development under Section 3 of the Planning and Development Act 2000 and need planning permission unless exempted.

Do I need planning permission to let my house on Airbnb?

Often, yes. Short-term letting of an entire house in a Rent Pressure Zone for more than 90 days a year requires planning permission, and home-sharing above the thresholds must be registered with the council. Outside RPZs, whether the change is material decides the question.

Is changing from one shop type to another exempt?

Generally yes, if both uses fall in the same use class under Part 4 of the Planning and Development Regulations 2001. Moving between classes, such as a shop to a takeaway or restaurant, typically needs permission.

Change of Use Planning Permission in Ireland

When you need planning permission for a change of use in Ireland, including commercial to residential conversions, short-term letting (Airbnb), and material change of use rules.

A "material change of use" is one of the most common reasons planning permission is required in Ireland. Under Section 3 of the Planning and Development Act 2000, changing how a property or land is used can constitute "development" requiring permission — even if no physical building works are involved.

What Is a Material Change of Use?

A change of use is "material" when it is significant enough to affect the surrounding environment, public amenities, or character of the area. The key factor is the impact of the new use, not just the fact that the use has changed.

Common examples that typically require planning permission:

Converting a house to apartments or bedsits
Converting a shop to a restaurant or takeaway
Converting a dwelling to a crèche or commercial office
Converting agricultural land to a car park or storage yard
Changing a pub to a nightclub (intensification of use)
Using a dwelling for short-term tourist letting (Airbnb — see below)
Converting a house to a bed and breakfast (over certain thresholds)

When You Don't Need Permission

Changes within the same use class are generally exempt from planning permission under the Planning and Development Regulations 2001. Ireland has a system of use classes — a change from one type of shop to another type of shop (within the same class) is typically not a material change of use.

However, any change between different use classes normally requires planning permission.

Fees for Change of Use

The planning application fee for a change of use depends on the floor area:

Floor Area	Fee
Up to 50 square metres	€80
51 to 200 square metres	€80 + €2 per sq m over 50
Above 200 square metres	€380 + €1 per sq m over 200
Change of use to dwelling/apartment	€65 per unit

See our full fees guide for the complete schedule.

Commercial-to-Residential Conversion Exemption

A temporary planning exemption allows the conversion of vacant commercial premises to residential use without planning permission, subject to conditions:

The premises must have been vacant for at least 2 years before works commence
The exemption covers properties with commercial uses in Classes 1, 2, 3, 6, and 12 (including pubs)
Maximum of 9 residential units per conversion
Works must be completed by 31 December 2028 (extended by S.I. 648 of 2025)
You must notify the planning authority in writing at least 2 weeks before starting, providing the Eircode, existing permitted use, and number of proposed units
The property must meet building regulations and fire safety requirements

This exemption is a significant opportunity for converting vacant commercial buildings in towns and cities into much-needed housing.

Short-Term Letting (Airbnb) Rules

Planning permission requirements for short-term letting depend on your situation:

Your principal private residence (PPR) — up to 90 days:

You can rent your entire home for short stays of less than 14 days at a time, up to a maximum of 90 days per year, without planning permission
The 90 days need not be consecutive

Your PPR — more than 90 days:

If you rent your entire PPR for more than 90 days per year, you need change of use planning permission

Home-sharing (renting a room while you live there):

You can rent a room in your home to short-term guests while you also occupy it — no planning permission required
No limit on the number of nights
May qualify for the rent-a-room tax relief

Second properties / investment properties:

Using a property that is not your PPR for short-term tourist accommodation always requires change of use planning permission
Planning authorities in areas of high housing demand are unlikely to grant permission for this use

Registration requirement: From May 2026, all short-stay accommodation (up to 21 nights) must be registered with Fáilte Ireland's Short-Term Tourist Letting Register. Platforms like Airbnb face penalties for listing unregistered properties.

Zoning Considerations

Your proposed new use must be consistent with the zoning objectives in the County or City Development Plan for your area. For example:

Land zoned "residential" may not permit commercial uses
Land zoned "neighbourhood centre" may permit a mix of retail and residential
Land zoned "open space" will not permit any building development

Check your zoning at MyPlan.ie or your local authority's online planning portal.
