Building Compliance Audit Checklist

What Is a BCA Audit of an Existing Building?

A BCA audit is an assessment of an existing building against relevant provisions of the National Construction Code (NCC), the Building Code of Australia (BCA) and other applicable building requirements.

The audit usually means checking documents, inspecting key parts of the building, and noting any possible compliance issues. The scope depends on the building’s type, age, current use, available records, and why the audit is being done.

A code compliance audit may identify issues relating to fire safety, building classification, accessibility, exits and egress, construction elements and other applicable requirements.

The results give owners and project teams a better idea of the building’s compliance status and show where more investigation is needed.

An audit doesn’t mean every difference between an existing building and the latest NCC rules must be fixed. What’s required depends on the building’s situation, the law, and any planned work or change of use.

What Triggers a BCA Audit?

There isn’t one event that always triggers a BCA audit. Owners usually request one when they want to understand compliance risks or see what a proposed change might mean.

1. Property Acquisition or Due Diligence

   Before buying a commercial or industrial property, buyers should know about any possible liabilities that could affect their investment.

   An audit can show compliance gaps, fire safety issues, accessibility problems, and possible upgrade needs. These findings help with due diligence, cost planning, and deciding if the property fits its intended use.

2. Refurbishment or Building Upgrades

   Refurbishment can highlight the current state of a building. Planned changes might affect access, fire separation, exits, building services, or other regulated features.

   A BCA audit shows the current compliance status before design work moves forward. This helps the project team know which rules apply to the planned work and where more checks are needed.

3. Change of Building Use

   Changing a building’s use can affect its classification and the compliance rules that apply.

   For example, converting an existing commercial space into another type of occupancy may introduce different requirements for fire safety, egress, accessibility or building services.

   An audit can help identify the implications of the proposed use before the owner commits to a design or fit-out.

4. Suspected Compliance Gaps or Safety Concerns

   Owners might request an audit if they notice questionable building changes, missing records, access problems, or concerns about fire safety.

   An assessment can record the issues and help decide if more investigation or repairs are needed.

   Where an immediate safety concern exists, the owner should arrange an appropriate specialist assessment rather than rely on a general compliance audit alone.

5. Planning for Long-Term Asset Management

   Property owners and asset managers may want a clearer view of compliance risks for a building or across their portfolio.

   A BCA audit can point out issues that might need attention during future maintenance, refurbishment, or redevelopment. The results can help plan and prioritise investigations and improvements.

Building Compliance Audit Checklist: What Should Be Checked?

The scope of an audit should reflect the building and the reason for the assessment. The following BCA audit checklist covers common areas for review, but it is not a substitute for a project-specific assessment.

1. Building Classification and Use

   Building classification determines which NCC provisions apply to a building. Check:

   • The documented classification against the building’s current use.
   • Whether different uses within the building require separate classifications.
   • Whether changes to occupancy or use affect the applicable requirements.
   • Whether the available approval records reflect the current configuration.

   Resolve classification uncertainties before assessing requirements for individual building elements.

   Applicable obligations depend on the building’s approval history, current use, and proposed work. The NSW Government’s guide to complying with the National Construction Code provides further guidance on understanding and meeting relevant code requirements.

2. Fire Safety and Life Safety Provisions

   Review the available fire safety documentation and inspect relevant provisions within the agreed audit scope.

   • Fire-resisting construction and compartmentation.
   • Fire doors and protection of openings.
   • Exit arrangements, travel distances and egress paths.
   • Relevant fire safety systems and supporting records.
   • Differences between documented provisions and observed site conditions.

   If concerns need testing, specialist checks, or fire engineering advice, note them for further investigation. A BCA audit doesn’t replace required inspections and maintenance of key fire safety measures.

3. Accessibility and Access Provisions

   Assess the building’s access arrangements against the requirements relevant to its use and circumstances.

   • Routes from site boundaries and parking areas to entrances.
   • Doorways, corridors, ramps, stairs and lifts.
   • Accessible sanitary facilities and relevant ambulant facilities.
   • Access to common areas and other applicable facilities.
   • Barriers that may require an access audit or specialist assessment.

   Finding a difference from the current standard doesn’t always mean an existing building must be upgraded. The actual requirements should be considered in context.

4. Exits, Egress and Circulation

   Focus on how the building’s layout affects occupant movement and access to exits.

   • Obstructions along exit paths.
   • Changes to internal layouts that may affect travel distances.
   • Alterations to doors, corridors or stairways.
   • Differences between available plans and actual site conditions.
   • Potential conflicts between circulation routes and other building elements.

   If there are undocumented changes that could affect exit routes, they should be looked into further.

5. Building Elements and Construction Details

   Review relevant construction details where they affect applicable building requirements.

   • Available information about construction type and fire resistance.
   • Relevant walls, floors, ceilings and other building elements.
   • Penetrations through fire-resisting construction.
   • Alterations that may have affected required building performance.
   • Visible defects requiring specialist investigation.

   A BCA audit doesn’t replace a structural condition assessment or a detailed check of hidden building parts.

6. Approvals and Supporting Documentation

   Compare the available records with the building’s current configuration and use.

   • Development consents and construction certificates.
   • Occupation certificates and other relevant approval records.
   • Architectural drawings and specifications.
   • Fire safety schedules and inspection records.
   • Previous compliance reports and records of alterations.
   • Documentation supporting approved Performance Solutions.

   Missing records don’t prove non-compliance, but they can limit what you can conclude and show where more questions are needed.

Building Condition Audit vs Compliance Audit

A building condition audit and a BCA compliance audit answer different questions. They may overlap in some areas, but one should not be assumed to replace the other.

A building might be in good shape but still have compliance issues. Likewise, it could have physical problems that need fixing, but those might not break BCA rules.

If both issues are important, you may need separate condition and compliance assessments.

How to Act on BCA Audit Findings

An audit report should help the owner see what needs attention, what needs more investigation, and how to plan the next steps.

1. Clarify which requirements apply.Figure out what rules affect the building, based on its approval history, current use, planned work, and the law.
2. Prioritise actions.Review the findings based on safety, obligations, project timelines, and the consequences of not fixing an issue.
3. Plan the work.Use the findings to decide on more assessments, bring in specialists, estimate costs, and coordinate upgrades with any planned refurbishment or redevelopment.

Not every finding means you need to start construction right away. Some may just need more paperwork or investigation before making a decision.
