Strata Insurance Coverage, Exclusions, Excesses and Policy Limits

Strata insurance is designed for properties with shared ownership, such as apartment buildings, townhouse complexes and other strata-titled schemes. It typically protects the building, common property and certain liability risks, but it is not a blanket guarantee that every type of damage, loss or dispute will be covered.

For owners corporations, strata committees and strata managers, understanding strata insurance coverage is only the first step. It is just as important to check the exclusions, excesses, policy limits and optional cover sections of the policy schedule and product disclosure statement. These details can affect whether a claim is accepted, how much is paid and what costs may still need to be met by the scheme or individual owners.

This article provides general educational information for Australian strata schemes. It does not replace the policy wording, legal advice or financial advice tailored to a particular building or owners corporation.

What strata insurance generally covers

Strata insurance policies vary between insurers and jurisdictions, but they commonly cover the physical building and common property owned or managed by the owners corporation or body corporate. This may include structural elements, shared facilities and liability protection associated with common areas.

Building and common property damage

A strata insurance policy will usually respond to insured events that damage the building or common property. Depending on the policy wording, this may include events such as fire, storm, impact damage, vandalism or other insured perils.

Common property can include areas and assets such as:

• roofs, external walls, stairwells, foyers and corridors;
• lifts, driveways, fences and shared car park areas;
• gardens, pools, gyms and other shared amenities;
• some fixed plant and equipment used by the scheme; and
• communal fixtures, fittings and furnishings, depending on the policy.

The exact boundary between common property and individual lot property depends on the strata plan, state or territory rules and the policy wording. This is why committees should avoid assuming that every fixture inside a lot is automatically covered by the strata policy.

Public liability for common areas

Public liability cover is a key part of many strata insurance policies. It may help protect the owners corporation if someone alleges they were injured or suffered property damage because of an incident connected with common property.

For example, a visitor may trip on a damaged common stair or slip in a shared area. Whether a claim is covered will depend on the circumstances, the policy terms and the insurer's assessment. Liability cover should not be treated as a substitute for regular maintenance, hazard reporting and good record-keeping.

Shared contents, fixtures and equipment

Some policies may include limited cover for contents or assets owned by the owners corporation, such as lobby furniture, shared appliances, gardening equipment or office equipment used for strata administration. Other items may need optional cover or may be subject to sub-limits.

Individual owners and tenants should not rely on strata insurance to cover their personal belongings. Contents inside an individual lot, such as furniture, electronics, clothing and personal valuables, are generally matters for separate contents insurance.

Why exclusions, excesses and limits matter

The headline description of a strata insurance policy can sound broad, but the practical outcome of a claim often depends on the detail. Four policy features are especially important:

Reviewing these areas before renewal can help an owners corporation identify gaps, request clarification and decide whether optional cover or changes to limits should be considered.

Common strata insurance exclusions to check

Exclusions differ between insurers, so the following examples should be treated as areas to check rather than a universal list. The policy wording and schedule will determine what applies to a particular scheme.

Wear and tear, maintenance and gradual deterioration

Insurance is generally intended for sudden and unexpected insured events, not routine upkeep. Policies commonly exclude wear and tear, corrosion, gradual deterioration, mould, rust, rot or damage that results from a lack of maintenance.

This distinction can be important. For example, a sudden insured water damage event may be treated differently from long-term leaking caused by poor maintenance. The owners corporation should keep maintenance records, repair reports and inspection documents to help show how the building has been managed.

Defects, faulty workmanship and non-compliant work

Some policies exclude damage caused by defective design, defective materials, faulty workmanship or non-compliant construction work. In some cases, resulting damage may be treated differently from the cost of fixing the original defect. The exact position depends on the policy wording.

Where a building has known defects, cladding concerns, waterproofing issues or past rectification works, the committee should disclose relevant information as required and seek guidance on how the policy responds.

Flood, storm surge and water-related events

Flood cover is not always automatic, and definitions can vary. Some policies distinguish between stormwater, rainwater, runoff, flood, actions of the sea, storm surge and other water-related events.

This can be particularly relevant in areas exposed to heavy rainfall, rivers, coastal hazards or overland flow. The owners corporation should check whether flood is included, excluded, optional or subject to a higher excess or specific sub-limit.

Individual lot contents and personal property

Strata insurance generally does not cover an owner's or tenant's personal contents. It may also exclude certain improvements, fixtures or fittings inside a lot if they are not considered part of the insured building or common property under the policy and applicable strata rules.

Owners should consider what they need to insure separately, such as contents, landlord insurance, loss of rent cover or other protection relevant to their individual circumstances.

Intentional acts, illegal activity and unauthorised alterations

Policies may exclude intentional damage by certain parties, illegal activity, unauthorised building works or alterations that have not been properly approved. Where a lot owner or resident undertakes work affecting common property or building services, the owners corporation should ensure approvals, records and insurance implications are considered before work begins.

Vermin, pests and contamination

Damage caused by vermin, insects, animals, contamination or infestation may be excluded or limited. There may also be restrictions for cleaning, decontamination or preventative work. If the property has recurring pest or hygiene issues, a maintenance plan may be just as important as insurance cover.

Vacancy, security and unattended areas

Some policies include conditions relating to security, occupancy, alarms, fire protection systems or the management of unattended areas. A claim may be affected if the scheme has not complied with policy conditions. Committees should check whether any warranties, conditions precedent or risk management obligations apply.

Understanding strata insurance excesses

A strata insurance excess is the amount the insured party must contribute towards a claim, or the amount deducted from the claim payment. Excesses are not just an administrative detail. They can influence whether a claim is financially worthwhile and how costs are shared.

Standard excesses and event-specific excesses

Many policies have a standard excess for general claims. Additional or higher excesses may apply to particular events or claim types, such as water damage, flood, cyclone, earthquake, glass, machinery breakdown or liability claims.

A scheme may also have different excesses for different parts of the policy. The policy schedule should be reviewed carefully so the committee understands which excess applies in which circumstances.

Multiple excesses for one incident

Some incidents can involve more than one type of damage or more than one section of the policy. Depending on the policy wording, this may raise questions about whether one excess or multiple excesses apply. The answer may depend on whether the damage is treated as one event, multiple events or separate claim components.

When an incident occurs, the strata manager or committee should ask the insurer or broker to confirm the relevant excess before authorising non-urgent repairs that may affect the claim process.

Who pays the excess?

Who ultimately bears the cost of an excess can depend on the circumstances, the strata scheme's by-laws, state or territory legislation, decisions of the owners corporation and whether a particular lot owner's actions caused or contributed to the claim.

For example, a water damage claim originating from one lot may raise different cost-sharing issues from storm damage affecting the roof. The committee should avoid making assumptions and should document decisions carefully.

Policy limits and sub-limits to review

A policy limit is the maximum amount the insurer will pay for a particular section of cover. A sub-limit is a lower cap that applies to a specific item, event or cost within the broader policy.

Building sum insured and reinstatement value

The building sum insured should reflect the cost to reinstate the insured property, not simply its market value. Reinstatement can involve demolition, debris removal, professional fees, compliance costs and rebuilding expenses. Market value may be higher or lower than the amount required to rebuild.

Owners corporations commonly arrange professional insurance valuations at appropriate intervals to help set an informed sum insured. Underinsurance can leave the scheme exposed if rebuilding costs exceed the policy limit.

Legal liability limits

Public liability limits should be checked against the scheme's risk profile, facilities and legal obligations. A small low-rise scheme may have different exposures from a large complex with lifts, pools, gyms, commercial areas or high visitor traffic.

The appropriate level of liability cover depends on the property and the insurer's available options. Committees should seek professional input if they are unsure whether the limit is suitable for the scheme's circumstances.

Temporary accommodation, loss of rent and alternative accommodation

Some policies include cover for temporary accommodation, loss of rent or similar costs if a lot becomes uninhabitable due to insured damage. These sections often have limits, sub-limits, time limits or eligibility conditions.

Owner-occupiers, investors and tenants may be affected differently. Individual owners should check whether they need additional cover outside the strata policy, particularly if they rely on rental income.

Catastrophe, escalation and extra rebuilding costs

After major events, rebuilding costs can rise because of labour shortages, material costs or increased demand for trades. Some strata policies include catastrophe or escalation benefits, while others may have limited or no additional allowance.

These benefits are not a guarantee that every increased cost will be covered. The wording should be checked to understand when the benefit applies and what limits or conditions are attached.

Office bearers, fidelity and voluntary workers

Some strata policies include or offer cover for office bearers liability, fidelity guarantee or voluntary workers. These covers can be relevant where committee members make decisions, handle funds or arrange voluntary activities on behalf of the scheme.

Each cover has its own exclusions, conditions and limits. Committees should check whether these sections are included automatically, optional, or subject to specific sub-limits.

Optional strata insurance cover to consider

Optional cover can help tailor a policy to the scheme's building, location and risk profile. It can also increase premiums, so the owners corporation needs to weigh the potential benefit against the cost and the likelihood of the risk.

Optional or additional cover may relate to areas such as:

• flood or other specific water damage risks;
• machinery or electrical breakdown for lifts, pumps, gates or air conditioning systems;
• theft, vandalism or malicious damage;
• office bearers liability;
• fidelity cover for misappropriation of funds;
• voluntary workers cover;
• catastrophe or cost escalation benefits; and
• additional temporary accommodation or loss of rent benefits.

Not every option will be relevant to every scheme. A building with multiple lifts, complex services and shared facilities may have different priorities from a small block with limited common property.

How exclusions and excesses affect claims

Claims outcomes depend on the insured event, the evidence provided, the policy wording and the insurer's assessment. An exclusion can prevent cover from applying. An excess can reduce the amount paid. A sub-limit can cap the payment even where the claim is otherwise accepted.

Good claims preparation starts before an incident occurs. Owners corporations should keep valuation reports, maintenance records, invoices, inspection reports, meeting minutes and correspondence. These records can help demonstrate the condition of the building and the steps taken to manage risk.

If an incident has occurred, the scheme should follow the insurer's notification requirements, take reasonable steps to prevent further damage and keep evidence of the loss. For a more detailed process overview, see our guide on how to make a claim on your strata insurance.

Premiums, excesses and the cost of cover

Strata insurance premiums can be influenced by many factors, including the location of the property, building age, construction type, claims history, insured value, risk controls, natural hazard exposure and the level of cover selected.

A higher excess may reduce premiums in some circumstances, but it can also increase the amount payable at claim time. Removing optional covers may reduce cost, but it can also create gaps. The right balance depends on the scheme's risk tolerance, budget and obligations.

Committees should be cautious about comparing policies on premium alone. A cheaper policy may have narrower cover, higher excesses, lower sub-limits or exclusions that are significant for the particular building. Conversely, a more expensive policy is not automatically more suitable. The comparison should focus on the overall policy terms, not just the annual cost.

Legal obligations and state-based requirements

Strata insurance requirements in Australia vary by state and territory. Owners corporations, bodies corporate and strata companies may have obligations relating to building insurance, public liability, valuations, records and decision-making.

This article does not set out all state and territory requirements. Committees should check the rules that apply to their jurisdiction and scheme type. They should also keep records of insurance decisions, valuations, quotes, renewals and disclosures to help show that the scheme has acted prudently.

If a scheme is uncertain about its obligations, policy interpretation or disclosure duties, it may be useful to speak with appropriately qualified professionals. You can also review available support options through our brokers page when considering specialist strata insurance guidance.

Checklist for reviewing a strata insurance policy

Before renewal, or after a significant building change, the owners corporation or strata committee can use the following questions as a practical review checklist:

• Building cover: Does the sum insured reflect a recent and appropriate reinstatement valuation?
• Common property: Are shared facilities, plant, equipment and fixtures clearly covered?
• Exclusions: Are there exclusions for defects, wear and tear, flood, gradual damage, illegal works or other risks relevant to the building?
• Excesses: What standard and event-specific excesses apply, and could multiple excesses apply to one incident?
• Sub-limits: Are there caps on temporary accommodation, loss of rent, machinery breakdown, catastrophe benefits or other important sections?
• Optional cover: Are optional sections needed for the scheme's location, facilities or risk profile?
• Disclosure: Have known defects, claims history, building works and risk issues been disclosed as required?
• Claims process: Does the committee know how to report incidents and what evidence to keep?
• Responsibilities: Is there a clear approach to who pays excesses in different situations?
• State rules: Have the relevant state or territory strata insurance obligations been considered?

When to review or update cover

Annual renewal is an obvious time to review strata insurance, but it should not be the only trigger. A review may also be appropriate when:

• major repairs, renovations or upgrades are completed;
• a new valuation indicates a change in rebuilding cost;
• the scheme adds facilities such as lifts, gates, solar systems or shared amenities;
• there has been a significant claim or recurring claims pattern;
• new defects or risk issues are identified;
• state or territory requirements change; or
• owners raise concerns about gaps in cover or excess allocation.

Key takeaways

Strata insurance can provide important protection for shared buildings, common property and liability risks, but the details of the policy matter. Owners corporations and strata committees should look beyond the premium and review what is covered, what is excluded, what excesses apply and what limits or sub-limits may restrict a claim payment.

The most effective review combines current building information, accurate valuations, clear maintenance records and a careful reading of the policy schedule and wording. Where the policy is unclear, committees should ask questions before a claim occurs, not after.

Because every strata scheme is different, the appropriate cover will depend on the building, location, claims history, facilities, legal obligations and insurer criteria. Regular review helps keep expectations realistic and supports better decision-making for the scheme as a whole.
