Managing multi occupied residential properties, such as HMOs and apartment blocks, places a substantial legal burden on the responsible parties. The shared nature of these premises introduces unique and complex fire safety risks which must be competently addressed by the building owners or their appointed agents. 

The Regulatory Reform (Fire Safety) Order 2005 places stringent demands on Landlord fire safety, requiring meticulous planning, certified installation, and rigorous maintenance.

If these obligations are ignored, this will expose tenants to severe danger and can cause the responsible person to face a fine, prosecution and potential imprisonment. Ensuring an apartment block's fire safety is not optional. 

The Legal Foundation: Responsibility in Multi-Occupancy

The core legal principle asserts that the responsible person is required to mitigate fire risk throughout all communal parts and, as clarified by the Fire Safety Act 2021, this duty often extends to the entire structure. 

Defining the Scope of the Responsible Person

Within an apartment block, the Responsible Person is typically the building owner or the management company responsible for any of the communal areas, such as stairwells, corridors, landings and plant rooms. For HMOs, the licence holder or owner is fully responsible for the entire building structure and all means of escape. 

This requires individuals to take reasonable steps to reduce the risk from fire, ensure any fire exits are clear, and provide appropriate fire detection systems. 

The Requirement for Fire Risk Assessments (FRAs)

The foundation of all landlord fire safety strategies is the Fire Risk Assessment. This mandatory formal review must be completed by a competent individual. It must identify all fire hazards, evaluate the potential risk to occupants and specify the necessary fire safety solutions. 

For multi-occupied properties, the FRA is an intricate document that must specifically address factors such as the ‘stay put’ policy often applied in apartment blocks, and the potential for fast fire spread prevalent in older HMO’s. 

The required comprehensive detail is comparable to the thorough planning established in A Guide to Fire Risk Assessments for Schools, but adapted specifically for residents while they are asleep. 

Core Requirements for Apartment Fire Safety

Effective apartment fire safety relies on two primary defensive elements, early detection to facilitate evacuation, and structural compartmentalisation to prevent fire spread.

Fire Detection and Alarm Systems (L-Categories)

The required alarm system for residential premises is governed by the L-Categories of British Standard BS 5839-6, which dictate the necessary level of detection based on the building's height and risk profile.

For HMOs, this often means a complex L2 or L3 system in common areas, ensuring that an alarm triggered in one part of the communal space sounds throughout the building. Apartment blocks often utilise L5 or L1 systems in common parts with interconnected smoke alarms installed within each flat. These systems require precise design and installation to ensure they communicate effectively without causing nuisance alarms.

Compartmentation and Passive Fire Stopping

Compartmentation is the design element that segregates the building into distinct, fire resistant cells to contain a fire in its room of origin, protecting residents in neighbouring flats. This includes fire rated walls, floors, and ceilings.

Passive fire stopping is the essential measure that seals any gaps or service penetrations (such as pipes or cables) that pass through these fire resistant barriers. The integrity of fire doors, which are also part of this compartmentation, must be rigorously maintained. 

Within our guide on Passive Fire Stopping in Construction, failure to maintain fire stopping measures renders the entire compartmentation strategy useless.
