High Rise Building Insurance: Unique Risks and Cover Types
High rise building insurance should reflect the building’s ownership, occupancy, construction, replacement costs and shared facilities. Ask how the proposed cover addresses property damage, liability, machinery and loss of rent, including relevant exclusions. ABS’s residential strata and commercial strata insurance services provide starting points for a review.
Standard commercial property policies are not designed for these exposures. If you own or manage a high-rise, or sit on a building association board, understanding how each layer of cover works is the starting point for a well-designed insurance programme.
High rise building insurance: identify the building’s exposures
High-rise buildings carry exposures that standard commercial property policies are not built to address. The structural complexity, occupancy density, and regulatory obligations of tall buildings require a purpose-built, multi-layer approach.
The most immediate difference is vertical risk. In a low-rise building, a burst pipe on level two affects level two. In a high-rise, the same burst pipe can cascade through ten or fifteen floors before it is detected, damaging common areas, individual units, mechanical plant, and electrical systems along the way. A single water event can trigger multiple simultaneous claims across different policy sections.
Central mechanical systems compound this exposure. High-rise buildings rely on shared lifts, pressurised water systems, central HVAC plant, and fire suppression infrastructure. When any of these fail, the impact is building-wide. Repair costs are significant, and the building may be partially or fully uninhabitable while work is completed.
Occupancy density creates a different category of risk. A building with 80 or 120 residential units, or a mixed commercial and residential tower, generates far more liability exposure than a single-tenancy commercial property. Slip-and-fall incidents in common areas, lift malfunctions, and inadequate security are all live exposures at scale.
Regulatory obligations add another layer. High-rise buildings are subject to building codes, fire safety standards, and, in some states, mandatory strata insurance legislation. When a building is damaged and must be repaired or rebuilt, the work must comply with current codes, not the codes that applied at original construction. That gap between old standards and current requirements is a significant cost driver that standard policies often do not cover.
A master policy held by the owners corporation or body corporate is the foundation of any high-rise insurance programme. It is a different instrument from an individual unit owner's contents or improvements policy, and the two must work together without gaps.
What Does High-Rise Building Insurance Actually Cover?
A high-rise insurance programme is not a single policy. It is a set of distinct cover types, each responding to a different category of risk. The core layers are:
Master property policy. This is the foundation. It covers the building structure, common areas, shared plant and equipment, and fixed improvements. The policy responds to physical loss or damage from insured events such as fire, storm, water damage, and impact. The sum insured must reflect the full replacement cost of the building, including demolition, debris removal, and professional fees, not just the market value of the property.
Loss-of-rents cover. When a building is damaged and units or commercial tenancies become uninhabitable, rental income stops. Loss-of-rents cover (also called business interruption cover in commercial contexts) maintains cash flow during the repair period. Without it, the owners corporation or building owner bears the full income shortfall while also funding repairs.
General liability cover. High-occupancy buildings generate a constant stream of third-party liability exposure. Visitors injured in common areas, contractors hurt on site, and residents affected by building defects can all give rise to claims. General liability cover responds to these premises-related injury and property damage claims, subject to the policy terms.
Umbrella or excess liability cover. For large high-rise buildings, the limits on a standard general liability policy may be insufficient. An umbrella policy sits above the primary liability layer and responds once those limits are exhausted. This is particularly relevant for mixed-use towers or buildings with significant public access.
Directors and officers (D&O) cover. Owners corporation committee members and body corporate board members make decisions about maintenance, repairs, and insurance on behalf of all lot owners. D&O cover responds to claims alleging that those decisions were negligent or in breach of duty. Without it, individual committee members can face personal liability for decisions made in their board capacity.
Ordinance-or-law cover. This is a distinct policy layer, not automatically included in a standard property policy. When a high-rise building is damaged and must be partially or fully rebuilt, current building codes apply to the reconstruction. If the original structure did not meet those codes, the cost of upgrading to compliance falls outside the scope of standard property cover. Ordinance-or-law cover specifically addresses this gap, covering the cost of demolishing undamaged portions of the building that cannot remain under current codes, and the additional cost of rebuilding to current standards.
A master building policy does not cover individual unit owners' personal contents, furniture, or owner-installed improvements above the original fit-out. Those items are generally excluded. Unit owners need a separate policy to cover them. The master policy covers the building; it does not cover what is inside each privately owned lot.
How Does High-Rise Building Insurance Cost Get Calculated?
Several factors drive the cost of a high-rise building insurance programme. Understanding them helps you anticipate where your premium sits and what you can do to manage it.
Building materials are a primary driver. Concrete construction carries materially lower fire risk than timber-frame structures. Research conducted for the National Ready Mixed Concrete Association found that builder's risk insurance for concrete buildings was as much as 80% cheaper than for wood-frame structures. While that figure comes from US builder's risk data, the underlying principle applies broadly: the fire resistance of your building's primary structure directly affects what insurers charge to cover it.
Cladding and fire safety defects have become one of the most significant premium drivers for high-rise buildings globally. A Financial Conduct Authority report found that mean insurance prices for affected high-rise buildings increased by 125% following the Grenfell Tower fire. That is a UK figure reflecting a specific regulatory response, but it illustrates the scale of impact that unresolved fire safety issues can have on premiums internationally. According to Insurance Business reporting on government survey findings, buildings with unresolved fire safety defects or unsafe cladding face insurance premium rates 56% higher than buildings without such defects. Australian buildings with unresolved cladding issues face similar pressure from insurers, even if the specific regulatory trigger differs. Australian buildings with unresolved cladding issues face similar pressure from insurers, even if the specific regulatory trigger differs.
Catastrophe exposure and location affect premiums significantly. In Australia, the main pressure points are cyclone-prone areas in Queensland, flood-mapped zones, and bushfire-adjacent locations. Buildings in these areas attract higher base premiums and, in some cases, sub-limits or exclusions for specific catastrophe events.
Occupancy type also matters. Mixed-use towers combining residential, retail, and commercial tenancies present a more complex risk profile than strictly residential buildings. Insurers price for the highest-risk occupancy present, and the interaction between different tenancy types, particularly where food preparation, public access, or hazardous goods storage are involved, can push premiums upward.
Claims history is a factor in every renewal. A building with a history of water damage claims, liability incidents, or fire events will face higher premiums at renewal, sometimes significantly so, regardless of what remediation work has been done.
The sum insured you set also affects your premium directly. Underinsuring to reduce premium is a false economy: if the building is destroyed and the policy limit does not cover full replacement cost, the shortfall falls on the owners corporation or building owner.
How to Set Up the Right Cover for Your High-Rise Building
Structuring a high-rise insurance programme correctly requires more than selecting a policy off the shelf. Work through each layer in a deliberate sequence, because gaps between layers are where underinsurance problems originate.
Determine building replacement cost to set policy limits. The sum insured on your master property policy must reflect the full cost of demolishing and rebuilding the structure from the ground up, including debris removal, professional fees, and any site-specific costs such as crane access for upper floors. Market value is not the right figure. Replacement cost is. An independent quantity surveyor assessment is the most reliable way to establish this figure, and it should be reviewed at every renewal, not just when the building was first insured.
Set loss-of-rents cover to maintain cash flow during repairs. Calculate the total annual rental income the building generates across all tenancies, residential and commercial. Your loss-of-rents limit should cover that income for a realistic repair period, which for a major structural event in a high-rise could be 18 to 24 months. Underestimating this period is a common mistake that leaves owners corporations carrying the income shortfall while repairs are still under way.
Establish general liability cover to protect against premises-related injury claims. High-occupancy buildings generate constant third-party liability exposure. Set a liability limit appropriate to the building's size, occupancy type, and the volume of public access it receives. For larger or mixed-use towers, consider whether an umbrella or excess liability layer is needed above the primary limit. Also confirm that your D&O cover is in place for committee and board members, who carry personal exposure for decisions made in their governance capacity.
Implement risk transfer by mandating tenant renters insurance. Your master building policy covers the structure and common areas. It does not cover individual tenants' contents, nor does it protect you from claims arising from a tenant's negligence, such as an unattended stove causing a fire. Requiring all residential and commercial tenants to hold their own renters or occupiers insurance as a lease condition shifts that exposure back to the party best placed to manage it.
Verify that protective safeguards are maintained to avoid claim denial. Central fire alarms, sprinkler systems, and other fire suppression infrastructure are not just safety features. They are policy conditions. If a claim arises and those systems were not maintained, tested, or operational at the time of the loss, the insurer may reduce or decline the claim. Confirm with your facilities manager that all safeguards meet the standards specified in your policy wording, and keep maintenance records as evidence.
Working through these steps in order gives your programme a logical foundation. You know what the building is worth, how long you can sustain a loss of income, and that liability, governance risk, and tenant exposure are each addressed by the right layer.
High-Rise Building Insurance in Queensland and New South Wales
High-rise buildings in Queensland and New South Wales operate under separate legislative frameworks, and the insurance obligations that apply to each state are not identical. Understanding the local requirements is essential before you structure your programme.
In Queensland, strata-titled buildings are governed by the Body Corporate and Community Management Act 1997 and its associated regulation modules. The body corporate is required by law to hold building insurance that covers the full replacement value of the insurable improvements on the scheme land. This includes the building structure, common property, and fixtures. The policy must cover reinstatement and replacement, not just market value. Body corporate committees in Queensland also carry governance obligations that make D&O cover a practical necessity, even where it is not strictly mandated.
Queensland's exposure to cyclone, flood, and severe storm events adds another dimension. Buildings in North Queensland and coastal areas face catastrophe-exposed premiums and, in some cases, sub-limits or exclusions for named cyclone events. Reviewing your policy schedule carefully for these sub-limits is critical, because a standard sum insured that looks adequate may not apply in full to a cyclone loss.
In New South Wales, strata schemes are governed by the Strata Schemes Management Act 2015. The owners corporation must insure the building for full replacement value and must hold public liability insurance meeting the statutory minimum. These are minimum requirements, and many buildings, particularly larger mixed-use towers, need higher liability limits than the statutory floor.
NSW also has specific obligations around building defects and cladding rectification. Buildings identified as having non-compliant cladding under the NSW Cladding Product Safety Initiative face additional scrutiny from insurers at renewal. Disclosure obligations apply, and failure to disclose known defects can affect the validity of a claim.
If your building is strata-titled, the programme needs to align with the relevant state legislation, not just with general commercial property insurance principles. Residential strata insurance is a distinct product category with its own policy structure built around those obligations.
What Are the Gaps That Leave High-Rise Buildings Underinsured?
Most high-rise underinsurance problems trace back to a small number of recurring gaps. Check your programme against each of these.
Outdated replacement cost valuations. Construction costs have risen sharply in recent years. A valuation carried out three or four years ago may be materially below current rebuild cost. If your sum insured has not been updated, you are carrying the shortfall.
Missing ordinance-or-law cover. This is a separate policy layer, not a standard inclusion. Without it, the cost of upgrading a partially damaged building to current code compliance falls outside your cover. For older high-rises, this gap can represent a significant uninsured liability.
No umbrella or excess liability layer. A primary liability limit that was adequate five years ago may not be sufficient for a building that has grown in occupancy or added commercial tenancies. Review the limit against current exposure, not historical precedent.
Unresolved cladding or fire safety defects. As noted in UK government data, buildings with unresolved fire safety defects face insurance premium rates 56% higher than compliant buildings. Beyond the premium impact, unresolved defects can create grounds for an insurer to dispute a fire-related claim. Rectification is both a safety obligation and an insurance one.
No requirement for tenant renters insurance. If tenants are not required to hold their own cover, the building programme absorbs exposures it was not designed to carry.
When Should You Use a Specialist Insurance Broker for a High-Rise?
High-rise buildings with cladding exposure or catastrophe risk sit outside the appetite of most standard commercial insurers. Access to a broad insurer panel is not optional when your building's cladding status, location, or occupancy mix narrows the field of willing underwriters.

Contact the team directly by phone or via an online quote request form, and a broker will work with you to identify the right cover for your specific building.
FAQs
Do RTM directors carry personal liability for insurance decisions made on behalf of the building?
Yes. Committee members and directors of an owners corporation or body corporate make decisions about maintenance, repairs, and insurance on behalf of all lot owners. If those decisions are later found to be negligent or in breach of duty, individual members can face personal claims. Directors and officers (D&O) cover responds to these claims and is a practical necessity for anyone in a governance role on a high-rise building, regardless of whether legislation strictly requires it.
What is ordinance-or-law cover and why do high-rise buildings need it?
Ordinance-or-law cover is a separate policy layer that pays for the additional cost of rebuilding a damaged structure to current building codes. It is not automatically included in a standard property policy. For high-rise buildings, which are often decades old, the gap between original construction standards and current code requirements can be substantial. Without this cover, the cost of demolishing undamaged portions that cannot remain under current codes, and the cost of upgrading the reconstruction to current standards, falls on the owners corporation or building owner.
Does a master building policy cover individual unit owners’ contents and improvements?
No. A master building policy covers the structure, common areas, and shared plant and equipment. It does not cover an individual unit owner's personal contents, furniture, or owner-installed improvements above the original fit-out. Unit owners need a separate policy to cover those items. The master policy and the unit owner's policy must be structured to work together without gaps, particularly where improvements such as upgraded kitchens or bathrooms are involved.
How much public liability insurance does a high-rise building typically need?
In New South Wales, the Strata Schemes Management Act 2015 sets a statutory minimum for public liability cover. That is a floor, not a recommendation. Larger buildings, mixed-use towers, and buildings with significant public access generally need higher limits. An umbrella or excess liability layer above the primary policy is worth considering for any building where the volume of occupants and visitors creates sustained third-party exposure.
What happens to a high-rise insurance claim if sprinklers or fire alarms were not maintained?
Sprinkler systems and central fire alarms are typically listed as protective safeguards in your policy wording, meaning their maintenance is a condition of cover. If a fire-related claim arises and those systems were not operational, not tested, or not maintained to the required standard at the time of the loss, the insurer may reduce or decline the claim. Keeping documented maintenance records and confirming that safeguards meet the specifications in your policy schedule is the only reliable protection against this outcome.
Conclusion
High-rise building insurance is not a single product. It is a programme of distinct layers, each addressing a specific category of risk that standard commercial property cover does not reach. The master property policy, ordinance-or-law cover, liability layers, D&O protection, and loss-of-rents cover all need to work together, and each needs to be set at limits that reflect the building's actual replacement cost and exposure profile.
Start by confirming that your replacement cost valuation is current, then work through the five steps in this guide to check each layer in turn. If your building has unresolved cladding issues, sits in a cyclone or flood zone, or has not had its programme reviewed in the past two years, those are the areas to address first.
