Minimum standards for rented accommodation in Ireland: damp, ventilation and heating
In short
Every landlord in Ireland must keep a rented home up to the Housing (Standards for Rented Houses) Regulations 2019 (S.I. No. 137 of 2019). The home must be kept in a proper state of structural repair and not defective due to dampness or otherwise. Every habitable room needs adequate ventilation, kitchens and bathrooms need ventilation to remove water vapour, and habitable rooms and bathrooms need permanently fixed heating the tenant can control. City and county councils inspect and enforce, with improvement notices, prohibition notices and fines of up to €5,000.
On 5 October 2026 the Department of Housing and the Residential Tenancies Board published a two-page leaflet summarising the rules. The leaflet summarises the 2019 Regulations rather than changing them. This page sets out the parts that matter for damp and mould, what council inspectors look for, and what happens when a home falls short.
Which homes the standards cover
The Regulations apply to every house let, or available to let, for rent, and "house" includes flats and maisonettes. That takes in private lets and homes let by local authorities and approved housing bodies. Three kinds of letting are excluded (Regulation 3):
- holiday lets;
- accommodation let by the HSE or an approved body with sanitary, cooking or dining facilities shared within the building;
- caravans, mobile homes and other movable structures let by a housing authority.
A repair standard is judged as what is reasonable in all the circumstances, having regard to the age, character and prospective life of the house (Regulation 2(2)). An older home is not held to a new-build finish, but it still has to be free from damp.
The damp, ventilation and heating rules
The middle column is the law. The right-hand column comes from the Department's guidelines for housing authorities (August 2024), which councils must have regard to: it is how inspectors judge the rule, not an extra legal requirement.
| Requirement | What the Regulations say | What inspectors look for |
|---|---|---|
| Free from dampRegulation 4(1) and (2) | A proper state of structural repair: sound inside and out, with roof, windows, floors, ceilings, walls, stairs, doors, gutters, down pipes and common areas in good condition and repair and not defective due to dampness or otherwise. | No evidence of dampness or water penetration through the roof, the windows or doors, or the floors, ceilings or walls. |
| Ventilation in habitable roomsRegulation 8(1) and (2) | Every habitable room has adequate ventilation, and every means of ventilation is kept in good repair and working order. | Natural ventilation: an openable window or door whose opening section is at least 1/20th of the floor area, and an unobstructed wall or window vent of at least 6,500 mm² to the outside. A chimney is not normally counted as ventilation. |
| Water vapour from kitchens and bathroomsRegulation 8(3); 7(2)(b); 5(2)(v) | Ventilation to remove water vapour from every kitchen and bathroom; a cooker hood or extractor fan venting to the outside; the bathroom separately ventilated. | A bathroom or WC with no openable window has a working extract fan with a 15-minute overrun, or a passive stack vent with humidity control, plus a 10 mm gap under the door or equivalent. |
| Heating the tenant controlsRegulation 6(1) and (4) | Every habitable room and any bathroom or shower room has a permanently fixed heater or heating system capable of effective heating, which the tenant can manage independently. A kitchen under 6.5 m² is not a habitable room. | Central heating controlled centrally by the landlord does not meet the rule unless there is another heating system the tenant controls. Heaters are in working order and serviced to the manufacturer's guidelines. |
Homes with mechanical ventilation
The guidelines describe three ventilation strategies: natural ventilation with intermittent extract fans, continuous mechanical extract ventilation (cMEV), and mechanical ventilation with heat recovery (MVHR). In a home with cMEV, each habitable room should have controllable background vents of at least 2,500 mm² equivalent area, and each wet room should reach a minimum boost extract rate:
| Wet room | Minimum boost extract |
|---|---|
| Kitchen (excluding cooker hood) | 13 l/s |
| Utility room | 8 l/s |
| Bathroom | 8 l/s |
| Toilet with no bath or shower | 6 l/s |
Where Part F of the Building Regulations 2019 applied to the home, an inspector may ask for the Ventilation Validation Certificate showing those rates were achieved. The control indicators should be where the occupant can see them, not in the attic.
Landlord and tenant: who is responsible
The guidelines summarise the split. The landlord maintains and repairs the home and the equipment provided with it, including wear and tear from normal use. The tenant must take due care, tell the landlord promptly when repairs are needed, and is responsible for damage, accidental or deliberate, that does not come from normal use. The Department says the RTB may have a role where a tenant's use of the home leads to it falling below a standard.
Where an inspection does not make it clear whether a home complies, the council may require the landlord to provide the evidence needed to show it does. For damp, that means a dated record of what was found, where, and why: moisture readings, the ventilation and heating in each room, and photos.
Inspections and enforcement
Enforcement rests with the city or county council. A person it authorises may enter and inspect a rented home at all reasonable times (section 18 of the Housing (Miscellaneous Provisions) Act 1992). Councils carried out over 82,700 rental standards inspections in 2025, and the government's Housing for All plan set a target of inspecting 25% of private tenancies each year.
- Improvement notice (section 18A). It states the council's reasons, identifies the regulation breached and directs the landlord to fix it within a set period. The tenant gets a copy. The landlord can object within 14 days, then appeal the council's decision to the District Court within a further 14 days. When the work is done, the landlord confirms it in writing, and the council confirms compliance within 28 days once satisfied.
- Prohibition notice (section 18B). If the improvement notice is not complied with, the council can direct that the home must not be re-let until the problem is fixed. The landlord can appeal to the District Court within 14 days, and the council must bring the notice to the public's attention in whatever way it considers appropriate.
- Prosecution (section 34). Breaching the Regulations, obstructing an inspector, ignoring an improvement notice or re-letting in breach of a prohibition notice is an offence: a fine of up to €5,000, up to 6 months in prison or both, and up to €400 a day if it continues after conviction. The court will normally order the landlord to pay the council's costs.
A tenant who thinks their home falls short can contact the housing section of their local council. They can also take a case to the RTB about the standard and maintenance of the home, after first writing to the landlord and giving a reasonable time to fix it.
Where DampApp Pro fits
Whether you are a surveyor instructed by a landlord before an inspection, or checking a complaint of damp and mould, the useful output is the same: a record that shows the condition of each room and the likely cause. DampApp Pro is built for that visit:
- On site and offline: record each room, wall and defect with moisture readings, ventilation readings and photos, with no signal needed.
- Evidence for the cause: temperature and humidity give dew point and condensation risk, so the report can separate condensation from rising, penetrating or leak damp.
- Dated photos: the report can show each photo's capture time from its EXIF data, or the time it was added.
- A report before you leave: the PDF is built on your device, with optional AI help to turn shorthand into clear wording you check.
- The rules to hand: the app's Standards & Regulations reference summarises the 2019 Regulations for work in Ireland.
Genuinely free to start: surveys work offline and free PDFs carry a small app footer. Upgrade to Pro when you're ready for your own branding and the full toolkit.
Are you the housing association, not the surveyor?
DampApp Pro is built for the person carrying out the inspection. If instead you're the housing association or council itself — running Awaab's Law compliance across an entire stock, with statutory clocks, work orders, a central management portal and case-management integration (NEC, Civica, MRI, Aareon and more) rather than one report at a time — that's a different job, and it's what our sister platform HousingSurvey Pro is built for.

What are the minimum standards for rented accommodation in Ireland?▾
They are set by the Housing (Standards for Rented Houses) Regulations 2019 (S.I. No. 137 of 2019), in operation since 1 May 2019. They cover structural repair and freedom from damp, sanitary facilities, heating, food preparation and laundry, ventilation, lighting, fire safety, refuse storage, gas, oil and electricity installations, and information for the tenant. Every landlord has a legal duty to make sure the home meets them.
Does a rented home in Ireland have to be free from damp?▾
Yes. Regulation 4 requires the home to be kept in a proper state of structural repair, which it defines as sound inside and out, with the roof, windows, floors, ceilings, walls and other parts in good condition and repair and "not defective due to dampness or otherwise". The leaflet the Department of Housing and the RTB published on 5 October 2026 puts it as "free from damp and in good structural repair".
What ventilation does a rented home need?▾
Every habitable room must have adequate ventilation, every kitchen and bathroom must have ventilation to remove water vapour, and all means of ventilation must be kept in good repair and working order (Regulation 8). The Department's guidelines for inspectors say that, in a naturally ventilated home, each habitable room should have an openable window or door whose opening section is at least 1/20th of the floor area, and an unobstructed wall or window vent of at least 6,500 mm², and a bathroom without an openable window needs a working extract fan with a 15-minute overrun or a passive stack vent with humidity control.
Who enforces the standards, and what are the penalties?▾
The city or county council. Its authorised officers may enter and inspect at all reasonable times. If a landlord breaches the Regulations the council can serve an improvement notice, and if that is not complied with, a prohibition notice that stops the home being re-let until the problem is fixed. Breaching the Regulations, ignoring an improvement notice or re-letting in breach of a prohibition notice is an offence: a fine of up to €5,000, up to 6 months in prison or both, and up to €400 for each day it continues after conviction.
Do the standards apply to council and housing association homes?▾
Yes. They apply to almost every home let or available to let, including homes let by local authorities and approved housing bodies. The exceptions are holiday lets, HSE or approved-body accommodation with shared sanitary, cooking or dining facilities, and caravans or mobile homes let by a housing authority. Council homes, housing association homes and private lets of at least 10 years have a lighter kitchen and laundry requirement: the landlord does not have to supply white goods.
Does DampApp Pro make a rented home compliant?▾
No. DampApp Pro records the inspection and produces the report; the landlord remains responsible for meeting the Regulations and the surveyor for their findings. Check the Regulations and your local authority's requirements before relying on a report.
