Apartment construction has been one of the most active sectors in the Irish construction economy for a sustained period. The demand for high-density residential accommodation in Dublin, Cork, Galway, Limerick, and other urban centres across Ireland has driven significant investment in apartment development, from inner-city build-to-rent schemes to suburban residential blocks and student accommodation developments near major third-level institutions.
Every apartment building of any significance in Ireland requires passive fire protection as a mandatory element of building control compliance. The fire resistance requirements for residential buildings are among the most stringent in the Irish building regulations, reflecting the vulnerability of people who are asleep in their homes when a fire starts and the challenge of evacuating a multi-storey residential building in the middle of the night.
This article covers the passive fire protection requirements for apartment buildings in Ireland and Northern Ireland, how those requirements are applied in practice on residential development projects, the specific challenges that apartment construction presents for the fire protection contractor, and how FireShield Ireland works with apartment developers, main contractors, and design teams on residential projects across Ireland.
FireShield Ireland carries out passive fire protection and structural steel fireproofing on apartment buildings and residential developments across all 32 counties of Ireland and throughout Northern Ireland.

Fire Resistance Requirements for Apartment Buildings in Ireland
Apartment buildings in the Republic of Ireland are classified under purpose group 2, residential, in Technical Guidance Document B. The fire resistance requirements for elements of structure in residential buildings depend on the height of the building, measured from ground level to the floor of the top storey used for residential accommodation.
For apartment buildings up to 18 metres in height, the required fire resistance for elements of structure is 60 minutes. This covers the majority of apartment buildings being constructed in Ireland at present, including four and five-storey apartment blocks that represent the most common form of medium-density residential development across the country.
For apartment buildings between 18 and 30 metres in height the required fire resistance for elements of structure increases to 90 minutes. This applies to taller residential blocks in urban centres where site constraints and planning policies encourage taller development.
For apartment buildings above 30 metres in height, which are uncommon in Ireland outside the most densely developed parts of Dublin city centre, the requirements become more demanding and a fire engineering approach is typically required to demonstrate compliance.
In Northern Ireland, Technical Booklet E applies broadly similar height-based requirements to residential buildings, with the same 60-minute requirement for buildings up to a specified height and increasing requirements for taller buildings.
The practical implication of these requirements for developers and main contractors is that structural steel fireproofing to either 60-minute or 90-minute standard is a mandatory element of building control compliance on virtually every apartment building project in Ireland. The cost of the fireproofing is therefore a fixed element of the development cost that cannot be reduced or deferred, and the programme for the fireproofing must be integrated into the overall construction programme from the outset.
Steel Frame Apartment Construction in Ireland
Apartment buildings in Ireland are constructed using a range of structural systems including reinforced concrete frames, cross-laminated timber frames, and steel frames. The choice of structural system depends on the building height, the site conditions, the programme, and the developer’s preferences.
Steel frame construction is increasingly common in apartment development in Ireland, particularly for medium-rise buildings where the speed of erection and the flexibility of the steel frame in accommodating open-plan layouts are design advantages. Modular and volumetric construction approaches, where apartment units are prefabricated off-site and assembled on site, frequently use steel frames for the modular units and for the building’s primary structure.
For any apartment building with a steel frame, structural steel fireproofing is required to achieve the fire resistance period mandated by the building regulations. This applies to steel columns, beams, and composite floor decks throughout the building. The required fire resistance period, either 60 or 90 minutes depending on building height, must be achieved for every structural element in the building.
The volume of structural steel requiring fireproofing on a typical apartment building is substantial. A five-storey apartment block with a steel frame might have hundreds of individual column and beam sections spread across five floor levels, all requiring fireproofing to the 60-minute standard. The fireproofing programme for a building of this scale requires careful planning and integration with the overall construction programme.
Monokote Spray Fireproofing on Apartment Buildings
On most apartment construction projects in Ireland the structural steel is concealed above suspended ceilings in corridors, service voids, and above the apartment unit ceiling finishes. In these concealed locations Monokote spray applied fireproofing is the most practical and cost-effective system for achieving the required structural fire resistance.
Monokote is applied directly to the steel surface, covers complex geometrical areas including beam-to-column connections and composite deck soffits efficiently, and does not require the surface preparation and multiple-coat application process that intumescent coatings require. On a busy apartment construction site where programme is tight and multiple trades are working simultaneously across multiple floor levels, the efficiency of Monokote spray application is a significant practical advantage.
FireShield Ireland is the only licensed Monokote applicator in Ireland. Any apartment development project in Ireland specifying Monokote for structural steel fireproofing is carried out by our team. We have applied Monokote on apartment construction projects across Dublin, Cork, Galway, Limerick, and all other major urban centres in Ireland and in Belfast and across Northern Ireland.

Intumescent Coatings on Apartment Buildings
While most structural steel in apartment buildings is concealed and protected with Monokote, there are typically areas of exposed architectural steel in apartment buildings that require intumescent coatings. Common locations include the entrance lobby and reception areas of apartment buildings where exposed steel columns or beams are part of the architectural design, covered external walkways and balcony structures with exposed steel frames, amenity areas and communal spaces within apartment buildings, and rooftop or roof terrace structures with exposed steel.
The finish quality required for intumescent coatings in apartment building lobbies and communal areas can be high, particularly on higher-specification residential developments where the quality of the communal spaces is a significant selling point. We carry out intumescent coating work on apartment building lobbies and communal areas to the finish quality standard required by the project specification.

Programme Management on Apartment Construction Projects
Programme management for structural steel fireproofing on apartment construction projects in Ireland presents specific challenges that arise from the nature of apartment construction programmes.
Apartment buildings are typically constructed floor by floor, with each floor being structurally completed before the floor above is commenced. The fireproofing of each floor should ideally be carried out before the follow-on trades, including mechanical and electrical first fix and the ceiling installation, move into that floor. This creates a fireproofing programme that progresses floor by floor through the building, with the fireproofing contractor working in sequence with the structural steel erection and the follow-on trades.
The challenge on many apartment construction projects is that the programme window available for the fireproofing on each floor is narrow. The structural steel erection is complete, and the follow-on trades are waiting to begin. The pressure to move the follow-on trades in quickly after the steel is erected can lead to the fireproofing programme window being compressed or the follow-on trades starting before the fireproofing is complete, creating a situation where access to uncoated steel is obstructed by trade activity and the programme for completing and verifying the fireproofing becomes complex.
Engaging FireShield Ireland at the pre-construction stage of any apartment project allows the fireproofing programme to be properly integrated into the overall construction programme. We provide programme estimates based on the structural drawings, identify any areas of the programme where the fireproofing and follow-on trade sequences need careful co-ordination, and attend pre-construction programme meetings to input into the overall programme at the fireproofing stage.
Fire Compartmentation in Apartment Buildings
Structural steel fireproofing is one element of the passive fire protection system in an apartment building. Fire compartmentation, the division of the building into separate fire compartments using fire-resistant construction, is equally important and involves a much larger number of individual construction elements.
In apartment buildings, fire compartmentation means that each apartment is enclosed as a separate fire compartment, with fire-resistant construction to all walls, floors, and ceilings separating it from adjacent apartments, common corridors, and other parts of the building. The required fire resistance for these compartment boundaries depends on the building height and the purpose group of the building.
Every service penetration through a compartment wall or floor in an apartment building must be fire stopped using certified products and systems. The volume of fire stopping required in an apartment building is substantial. Every pipe, cable, duct, and conduit that passes through the wall or floor between an apartment and the common corridor, between one apartment and another, or through the floor to the apartment above must be fire stopped to the required standard.
Fire stopping deficiencies are among the most common passive fire protection failures found in apartment buildings during building control inspections and fire safety audits in Ireland. The large number of individual penetrations, combined with the programme pressures of apartment construction and the number of trades involved in creating service penetrations, means that fire stopping is frequently omitted or inadequately installed.
Details of the passive fire protection requirements for apartment buildings, including compartmentation and fire stopping, are covered on our passive fire protection page.
Documentation for Apartment Building Control
The building control process for apartment buildings in Ireland and Northern Ireland involves a Fire Safety Certificate application, building control inspections during construction, and a completion certificate at the end. The structural steel fireproofing installation must be documented to the standard required for building control sign-off.
For apartment buildings in the Republic of Ireland, the Fire Safety Certificate application submitted to the local authority fire service includes details of the structural fire protection system, including the products to be used and the fire resistance periods to be achieved. The completion certificate confirms that the fireproofing has been installed in accordance with the certified design.
The documentation provided by FireShield Ireland at the completion of a structural steel fireproofing installation on any apartment building includes the product data sheets and certification for the specific Monokote grade or intumescent coating system applied, the fire resistance calculations confirming the required fire resistance period for each structural section type on the project, the quality control records from the installation, and a completion certificate. This documentation supports the completion certificate submission to building control and is provided as standard on every project.
Build-to-Rent and Large-Scale Residential Development
The Irish residential market has seen significant growth in build-to-rent development, where large apartment schemes are developed specifically for the private rental market rather than for individual sale. These schemes, which are typically larger than standard apartment developments and often involve multiple buildings on a single site, are major construction projects that require comprehensive passive fire protection planning and execution.
Build-to-rent developments in Dublin in particular have been a significant source of residential construction activity over the past several years. Sites with multiple apartment blocks, shared amenity buildings, and podium car parking structures all involve structural steel fireproofing requirements across multiple buildings on a co-ordinated programme.
We work with the main contractors and developers delivering build-to-rent residential schemes in Ireland, providing a co-ordinated fireproofing service across multiple buildings on large residential development sites. Our programme management capability for multi-building residential sites reflects our experience of working on these complex, high-volume projects.
Student Accommodation and Purpose-Built Student Accommodation
Purpose-built student accommodation has been a growth sector in Irish construction over the past decade, driven by increasing third-level enrolment and the demand for purpose-built accommodation near major universities and institutes of technology in Dublin, Cork, Galway, Limerick, and other third-level cities.
Student accommodation buildings are classified as residential in the Irish building regulations and the fire resistance requirements for elements of structure are the same as for apartment buildings of equivalent height. The construction form of modern student accommodation buildings, often steel frame with a combination of concealed and exposed structural steel, means that both Monokote spray applied fireproofing and intumescent coatings are typically required.
We carry out structural steel fireproofing on purpose-built student accommodation projects across Ireland and Northern Ireland, working with the specialist student accommodation developers, main contractors, and design teams active in this sector.
