Rent increases in private rented housing

The amount of rent you pay for a property is agreed between the landlord and tenant at the start of a tenancy. Private landlords must follow certain procedures if they want to raise the rent. The rules are set out in residential tenancies legislation.

These rules about rent increases apply to private rented housing. They do not apply to housing let by local authorities or approved housing bodies, as they charge differential rents based on household income. While approved housing bodies come under the residential tenancies legislation, their rent reviews are carried out in accordance with their tenancy agreements, or no more than once in any 12-month period.

Student-specific accommodation comes under the remit of the Residential Tenancies Board (RTB). This means that student tenancies are covered by residential tenancies legislation and these tenants have most of the same rights as private tenants, including that their landlords must follow the rules about increasing the rent.

Rent Pressure Zones (RPZs) are areas where rents are highest and rising quickly. An area must meet certain criteria to become an RPZ. In these areas, annual rent increases are capped.

RPZs were introduced on 24 December 2016. They were to remain in place until 31 December 2024. But, on 14 May 2024, the Government agreed to extend them until 31 December 2025.

See below for the list of areas that are Rent Pressure Zones.

How are rent increases in RPZs calculated?

The system for calculating allowable rent increases in RPZs has changed a number of times.

Since, 11 December 2021, annual rent increases in RPZs are capped in line with the rate of general inflation or 2% a year, whichever is lower. So, if your landlord reviews the rent every 12 months and the rate of general inflation is 1.5%, then your rent can only be increased by a maximum of 1.5%. However, if the rate of general inflation is higher than 2%, for example, 3%, the rent can only be increased by a maximum of 2%.

If your landlord has not reviewed the rent for a number of years, the 2% cap applies every year. So, for example, if you moved into rented accommodation in December 2016 and the rent hasn’t changed since then, the general inflation rate would apply when calculating the rent increase. This is because the inflation rate between December 2016 and December 2021 was 6.6%, which is lower than the 10% that would apply under the 2% per year condition (2% per year for 5 years = 10%). The RTB’s Rent Pressure Zone calculator applies both of these conditions and calculates the allowable rent increase for you.

From 16 July 2021 to 10 December 2021, annual rent increases in RPZs were only capped at the rate of general inflation, as set out in the Harmonised Indices of Consumer Prices (HICP). But, due to rising inflation these rules were changed to include the new 2% per year condition. This was introduced under the Residential Tenancies (Amendment) (No. 2) Act 2021. The RTB has published a guidance document (pdf) highlighting the changes this legislation brought in and what they mean for landlords and tenants.

Between 24 December 2016 and 15 July 2021 rent increases in RPZs were capped at 4% per year.

The RTB has general information about RPZs, as well as detail on the Harmonised Indices of Consumer Prices (HICP), and how it relates to RPZs.

There is more information about Rent Pressure Zones and other measures on rtb.ie.

Under the Residential Tenancies Act 2004, landlords cannot charge more than the open market rate of rent. Market rent (for properties outside Rent Pressure Zones) is defined as ‘the rent which a willing tenant not already in occupation would give and a willing landlord would take for the dwelling’. The RTB publishes a quarterly index of rents, which you can use to check current market rents. Read more about market rent and the rent index.

A tenant or a landlord can request a rent review. A rent review can result in an increase or reduction in the rent. Rent Pressure Zones and areas outside Rent Pressure Zones have different rules for rent reviews.

Rent reviews in Rent Pressure Zones

Rent increases in Rent Pressure Zones are capped and there are limits on how often the rent can be reviewed. There are different rules about the limits and frequency of rent reviews depending on if the tenancy in the Rent Pressure Zone is an existing or new tenancy.

Rent reviews for a new tenancy in an RPZ

For a new tenancy in a Rent Pressure Zone, the landlord can review the rent once every 12 months. The landlord must give the tenant the following information, in writing, at the start of the tenancy:

• The amount of rent that was last set for the property
• The date the rent was last set for the property
• A statement as to how the rent set for the property has been calculated, having regard to the Rent Pressure Zone calculator

The rent being set should not be more than local market rents for similar properties

Rent reviews for an existing tenancy in an RPZ

If a tenancy is already in existence when an area becomes a Rent Pressure Zone, the first rent review can take place 24 months after either of the following:

• The start of the tenancy
• The date you were notified in writing of your last review

Subsequent rent reviews can take place after 12 months and must adhere to the RPZ rules.

Exceptions to rent limits in an RPZ

There are 3 exceptions to the rent limits applied in Rent Pressure Zones:

1. Properties that have not been let at any time in the previous 2 years
2. Properties in protected structures or proposed protected structures that have not been let in the previous year
3. Properties that have been substantially changed. (A ‘substantial change’ in this situation is defined in the Residential Tenancies (Amendment) Act 2019. The RTB website has details of the types of substantial change required).

Even if a property qualifies for one of these exemptions, the new rent set must still be in line with market rent for similar properties in the area.

If a landlord wants to get an exemption from rent limits in an RPZ area, they must notify the RTB within 1 month of setting the rent by completing the RTB’s RPZ Exemption Form (pdf).

The RTB can investigate and sanction landlords who do not comply with RPZ rules. There are penalties for landlords who do not follow rent increase limits in RPZs, provide false information about an exemption in an RPZ area or do not notify the RTB about availing of an exemption.

Rent reviews outside of Rent Pressure Zones

Your rent cannot be reviewed until 24 months after the start of your tenancy. If your rent was reviewed at any time in the last 24 months, it cannot be reviewed again until 24 months after the date of the last review. This rent certainty measure is in place until 31 December 2024.

When the 24-month period is over your landlord must give you at least 90 days’ notice of a change in rent. This written notice must state the amount of the new rent and date the new rent will take effect.

Your landlord cannot charge more than 'market rent' which is the going rate for your type of accommodation in the area you live.

Calculating allowable rent increases

You can use the RTB’s calculator to check if your property is in a Rent Pressure Zone and to work out if the rent can be raised and, if so, by how much. You will need to enter your address or Eircode, the current rent and the date when the rent was last set.

Notice of rent review

Once the required period (12 or 24 months) has elapsed, your landlord can issue a notice of rent review.

The landlord must give you proper notice of the amount of the proposed new rent and the date from which it is to take effect. Landlords must use the RTB’s Notice of Rent Review Form (pdf) when issuing a rent review. Landlords should fill out the sections of the form that are relevant to them and should not delete or change any of the form. Other forms, emails, text messages and spoken messages are not valid forms of notice.

You must get at least 90 days’ notice of a rent review. This means that the new rent cannot apply until 90 days after the notice has been issued.

The landlord must also notify the RTB of the revised rent so that it can update the registration details of the tenancy. The landlord can do this online using the RTB’s online account system, or by completing the RTB’s Tenancy Update Form (pdf) and returning it to the RTB. The form can be emailed to registrations@rtb.ie, or posted to the RTB. There is no fee for updating this information with the RTB. The RTB’s website has more information about updating your tenancy details.

Tenants requesting a rent review

As a tenant, you can ask your landlord to review the rent if:

• You think it is more than the current market rate for the property or
• You want a new review and more than 24 months have passedhttps://www.rtb.ie/registration-and-compliance/setting-and-reviewing-rent/rent-pressure-zones-setting-rent-and-rent-reviews#Exemptions%20to%20the%20Rent%20Pressure%20Zone%20rental%20cap

Threshold, the national housing charity, publishes detailed advice on how to deal with rent increases. You can contact Threshold for advice on your particular situation – see ‘Where to apply’ below’.

If there is any dispute about the amount of rent being proposed, either side can refer the dispute to the RTB. If you are claiming that the proposed rent is higher than the market rate, you should provide evidence of rental rates for similar properties in the same area.

If the landlord has given you a valid written notice of the rent increase, you must contact the RTB with your dispute before the date that the new rent comes into effect or within 28 days of getting the notice, whichever is later. There is no time limit if the notice is not valid.

You must continue to pay your rent until the case has been determined by the RTB.

Protecting your tenancy

You can contact Threshold’s Tenancy Protection Service on 1800 454 454 for general support, advice and advocacy around protecting your tenancy.

If you are getting (or applying for) Rent Supplement, there may be flexibility in cases where landlords seek rents that are above the Rent Supplement limits. This applies to existing tenants and to new Rent Supplement applicants. The circumstances of tenants are considered on a case-by-case basis and rents increased above the set limits as appropriate. Contact the local office that administers your Rent Supplement. The Tenancy Protection Service can help you in making an application.

The Department of Social Protection, in conjunction with Threshold, operates a special protocol for tenants on Rent Supplement in areas where supply issues are particularly acute - Dublin, Kildare, Meath, Wicklow, Cork city and environs, Galway, Mayo and Roscommon. Contact the Tenancy Protection Service on 1800 454 454.

The RTB deals with disputes between landlords and tenants about rent increases. There are 2 stages to the RTB’s dispute resolution process. Stage 1 is confidential mediation or adjudication, and Stage 2 is an appeal of the mediator’s or adjudicator’s decision, which is a public hearing by a 3-person Tenancy Tribunal. For more information see our document resolving disputes between landlords and tenants.

The RTB can also investigate and sanction landlords who do not comply with RPZ rules. See the RTB’s website for more information about what can be investigated and how to make a complaint.
