S.I. 137 Minimum Standards: A Room-by-Room Compliance Checklist for 2026

Every rental property in Ireland, private or social, has to meet a baseline set out in Statutory Instrument 137 of 2019 (and amended in 2022 and 2024). The standards cover structural integrity, ventilation, heating, fire safety, electrical safety, sanitation and food preparation. Failure on any one is a fail on the whole inspection.

Local Authorities run the inspection programme. Annual inspection volumes have climbed every year since 2022 and the 2025 Housing Agency report flagged a 28% non-compliance rate at first inspection. In other words, more than one in four properties fails on the first visit.

This piece is a practical, room-by-room checklist of what an inspector actually looks at and what trips most landlords up. It is not a substitute for the full text of S.I. 137, but it covers the 90% of items that determine whether you pass or fail.

Kitchen

• Sink with cold and constant hot water
• Cooker with four rings and an oven (single-ring camping stoves do not qualify)
• Extractor fan or openable window for ventilation
• Adequate food storage (cupboard plus fridge or fridge-freezer)
• Safe gas connection if applicable, with valid Bord Gáis Networks cert

The most common kitchen fail is ventilation. A sealed double-glazed unit with no extractor and no openable window is a fail. Fix is a wall-mounted extractor venting to outside.

Bathroom

• Bath or shower with hot and cold water
• WC with cistern
• Wash-hand basin
• Mechanical extractor or openable window
• Adequate ventilation must clear steam in 5-10 minutes

A surprising fail point is the shower head temperature. The 2024 amendments require thermostatic mixers in newly fitted showers. A pure manual mixer is acceptable in existing installations but flagged at next replacement.

Fire safety

• Mains-wired smoke alarm with battery backup on every storey
• Heat alarm in the kitchen
• Carbon monoxide alarm where any combustion appliance is present
• Fire blanket in the kitchen
• Fire-resistant doors on internal kitchen entrance in apartments

Battery-only smoke alarms are no longer acceptable. Self-contained 10-year-battery alarms count, but a hard-wired interconnected system is the cleanest pass.

Electrical safety

• Valid RECI or Safe Electric certificate, normally renewed every 10 years
• RCD protection on all sockets
• No exposed wiring or damaged sockets
• Distribution board labelled and accessible

Cert renewal cycle is the under-counted item. Most failed inspections that lead to a notice to remediate are failed on missing or expired electrical certs, not actual electrical faults.

Structure, damp and mould

• Sound roof, walls, windows, floors
• No visible damp, mould or condensation staining
• Adequate insulation in line with the BER certificate stated
• Working heating system in every habitable room

The 2024 amendments tightened the damp and mould threshold. A single damp patch behind furniture is now flagged, where previously inspectors gave a verbal warning. The remediation has to address the cause, not just paint over the surface.

How Rentalize handles this for you

Rentalize Core tracks the S.I. 137 inspection due date for every unit, schedules pre-inspection self-checks against this checklist, stores the compliance certs (electrical, gas, BER) with renewal reminders, and produces the inspector-ready report on demand. Rentalize 360 offers the same on a phone for 1-10 property landlords.

Smaller portfolios get caught out by certificate renewal more than by actual disrepair. Software solves the renewal-tracking problem in five minutes a year.

Frequently asked questions

What is S.I. 137?

Statutory Instrument 137 of 2019 (as amended) sets the minimum standards every rental property in Ireland must meet, covering structure, ventilation, heating, fire safety, electrical safety and sanitation.

Who enforces S.I. 137?

Local Authority inspectors. They have the right to enter, fail and require remediation. Failed properties cannot be relet until remediated.

How often will my property be inspected?

There is no fixed cycle. Inspections are triggered by tenant complaint, HAP/RAS scheme entry, or the Local Authority’s own programme. Most authorities run a rolling cycle aiming for inspection at least once per tenancy.

What happens if I fail an inspection?

You receive an Improvement Letter, then potentially an Improvement Notice with a remediation deadline. Persistent non-compliance is a Class C offence.

Are battery-only smoke alarms acceptable?

Self-contained 10-year sealed alarms are accepted. Replaceable-battery only alarms are not. Mains-wired with battery backup is the safest pass.

Does S.I. 137 apply to social housing?

Yes. Local Authority and AHB stock is subject to the same minimum standards, with internal inspection programmes.
