Fire Escape Routes in HMOs: Legal Requirements & Common Mistakes

A bike in the hallway. A suitcase wedged against a fire door. A chest of drawers gradually migrating from a bedroom into the corridor. These things happen in HMOs every week, and when they do, the liability falls on you, not your tenant. That is the legal reality of Article 14 of the Regulatory Reform (Fire Safety) Order 2005 — and it catches a lot of landlords off guard.

As the responsible person for your HMO, you have a continuous obligation to keep escape routes clear, lit, and available at all times. The law does not care that you did not put the bike there. If it is blocking an escape route when an inspector arrives, you are the one facing prosecution.

What the Law Actually Requires

Article 14 of the Regulatory Reform (Fire Safety) Order 2005 sets out the core obligation: escape routes must be kept clear and available for use at all times. This applies to every part of the route from each occupied room to the final exit — corridors, stairwells, landings, and external paths to the street.

The LACORS Housing Fire Safety Guide — published in 2008 and still the benchmark used by local authority inspectors — sets out the physical standards your escape routes must meet. These are not recommendations. Councils apply LACORS directly when assessing HMO licensing applications and enforcement notices.

BS 9792:2025, which came into effect in 2025, reinforces this further. Courts now treat a fire risk assessment that fails to identify escape route deficiencies as evidence of an inadequate assessment overall. If yours was completed before 2025, it is worth confirming it was carried out to the updated standard.

The Physical Requirements

For most HMOs, escape routes must meet the following minimums under LACORS guidance:

• Corridor width: 750mm minimum where travel is in one direction; 1,100mm where corridors carry two-way traffic or serve multiple rooms
• Doors onto escape routes: FD30S specification — 30 minutes fire resistance, smoke-sealed, and fitted with a working self-closing device
• Emergency lighting: Required in all internal corridors and stairwells that rely on artificial light; battery-maintained units that activate when mains power fails
• Signage: Direction signs where the route is not immediately obvious; "Fire Exit" signs on final exit doors
• Final exits: Must open from the inside without a key at all times

Bedroom doors that open directly onto an escape corridor must also be FD30S — a requirement missed regularly in older converted HMOs where original internal doors are non-rated and lack self-closers. The full specification is covered in our guide to HMO fire door requirements and compliance.

The Continuous Duty Problem

This is where many landlords misunderstand their position. Completing a fire risk assessment and confirming escape routes are compliant does not protect you indefinitely. The RRO 2005 imposes an ongoing duty, not a one-time obligation.

If a tenant moves a wardrobe into a corridor six months after your assessment, and an inspector visits the following week, you are in breach. The assessment was fine. The corridor was compliant on the day. It does not matter. The route is obstructed today, and today is what gets recorded.

This is not theoretical. At Wirral Magistrates' Court, Newsham Park Estates Ltd was fined £27,900 after inspectors found a rear fire escape padlocked and a shipping container blocking the exit. In South Gloucestershire, a landlord was found in breach of an Emergency Prohibition Order when the shared kitchen had been positioned in the middle of the main escape route, with a makeshift kitchenette blocking the secondary exit — both arrangements that had developed gradually without action from the landlord.

The Most Common Mistakes

These are the escape route failures that appear most frequently in prosecution cases and HMO licence refusals:

• Tenant storage in corridors and stairwells. Bikes, pushchairs, boxes, suitcases. The most common obstruction by a distance, and often tolerated because challenging tenants feels difficult.
• Propped fire doors. Self-closers are inconvenient. Tenants wedge them open. A propped FD30S door provides zero compartmentation — it is just a door.
• Wrong door specification. Non-fire-rated doors where FD30S is required, or fire doors with missing intumescent strips, damaged seals, or gaps around the frame.
• No emergency lighting. Inner corridors with a single light fitting and no battery backup. Compliant in the day, dangerous in a power cut at 2am.
• Corridors narrowed by conversion works. Partition walls added to create extra lettable rooms, reducing corridor widths below minimum. Sometimes done with planning permission but without fire safety input.
• Inner-room arrangements. A room where the only means of escape passes through another occupied bedroom. Common in attic and basement conversions.
• Locked or stiff final exits. Doors with additional deadbolts, corroded mechanisms, or swollen frames that require significant force to open.

What to Check Every Quarter

An annual fire risk assessment is not enough to maintain escape route compliance on an ongoing basis. A quarterly walk-through takes under 30 minutes and substantially reduces your enforcement risk.

1. Walk every escape route from the top floor to the final exit. Note anything that reduces usable width or blocks access.
2. Check every fire door: self-closer functional, door closes fully into the frame, intumescent strips and smoke seals intact, no gaps visible around the frame edges.
3. Test emergency lighting. Most modern fittings have a test button — hold for three seconds and confirm the indicator shows the battery is charged.
4. Confirm all fire exit signs are visible and unobstructed.
5. Open and close each final exit door. Mechanisms should operate without excessive force and lock back correctly.
6. Record findings and any remedial actions taken in your fire safety log.

If you issue tenancy agreements, include a clause specifying that communal areas and escape routes must be kept clear and that storing items in corridors or stairwells is a breach of tenancy. This does not transfer the legal liability to your tenant, but it creates a basis for enforcement and demonstrates to inspectors that you are actively managing the obligation.

What Happens When Enforcement Comes

Under the Fire Safety Act 2021, magistrates' courts can impose fines of up to £30,000 per offence. Crown Court proceedings carry unlimited fines and up to two years' imprisonment. A single inspection revealing a blocked escape route, a propped fire door, and absent emergency lighting is three separate offences.

Beyond fines, an Emergency Prohibition Order can be issued on the spot, removing tenants immediately and prohibiting occupation until remedial works are signed off. For a landlord relying on rental income, that is often more damaging than the penalty itself. The knock-on effect on HMO licence renewal compounds the problem further. Our post on what happens when you fail HMO fire safety requirements covers the full enforcement picture.

Next Steps

If you have not walked your escape routes in the last three months, do it today. Twenty minutes now is worth considerably more than a prohibition order later.

A proper fire risk assessment should identify every escape route deficiency and produce a written action plan with deadlines. FRASafe guides you through a BS 9792:2025-aligned assessment — free to complete, £45 for the council-ready PDF. Start your HMO fire risk assessment here.
