Commercial Property / Due Diligence Report

A commercial property inspection tells you what you are really buying, leasing or developing. Tyrrells carries out independent, multi-disciplinary inspections and due diligence reports on commercial property across Sydney, regional NSW and the ACT, so hidden defects, non-compliant changes and future repair costs come to light before exchange, not after settlement.

A commercial property due diligence report evaluates a property’s condition, compliance and risks before purchase, lease or financing. It identifies defects in structure, building services, design, maintenance and statutory compliance, along with likely repair costs and tenancy risks. Buyers, investors, landlords, tenants and lenders use it to make informed decisions and to negotiate with evidence in hand.

What’s Covered in a Tyrrells Commercial Inspection

We tailor the scope to the property and to your role in the transaction. A typical commercial inspection covers:

Structural Integrity

Assessment of foundations, concrete framing, structural steel, load-bearing walls and roof trusses. Where a defect needs closer analysis, we can follow up with an engineering report.

Building Envelope & Roofing

Exterior cladding, waterproofing membrane integrity, gutters and roof sheeting.

Building Services Overview

A visual check of mechanical (HVAC), electrical, plumbing, lift installations and fire safety systems.

Safety & Compliance

OHS hazard identification, trip hazards, access compliance and basic fire safety checks. For a dedicated workplace assessment, see our OHS/Safety Report.

Dilapidation & Lease Handover

Baseline condition records before construction work starts nearby, or at lease commencement and expiry. We also prepare stand-alone dilapidation reports and lease check reports.

What’s Included in Our Commercial Due Diligence Report

A written due diligence report is usually available within three to seven business days of the inspection, depending on the size and complexity of the asset. Our commercial property due diligence report typically includes:

• Basic property details: lot and building size, floor number, property type, parking, zoning and current use
• Building evaluation: assessment of each element of the property’s structure, services and interior/exterior finishes
• Specialist inspections: reports from building inspectors, contractors, engineers, plumbers and other consultants
• Tenant information review: analysis of tenant agreements, occupancy and lease conditions
• Seller disclosures: review of historic operating statements, capital improvement schedules, service agreements and completed building permits

…and more. For more information about specific coverage, call us on 1300 131 270.

Why Due Diligence Matters for Commercial Purchases

Commercial deals in Sydney, regional NSW and the ACT carry real financial and legal exposure. Due diligence identifies current and potential defects, so you understand a property’s condition before you invest.

Uncovers Serious Issues

Commercial properties can conceal problems in air conditioning, lifts, fire safety, electrical systems and OHS compliance because of their structural and operational complexity. Our reports highlight immediate concerns, significant defects and any areas that need further specialist investigation before you commit to purchase.

Enables Informed Buying Decisions

Our due diligence report gives buyers detailed information on structural condition, statutory compliance (NCC/BCA), potential repair costs and tenancy risks, supporting price renegotiation or contract withdrawal if necessary.

Mitigates Financial Risks

By prioritising urgent issues and coordinating specialist assessments, our reports help prevent unexpected costs after purchase, such as major repairs or unforeseen legal liabilities.

FAQs

What is due diligence in commercial property?

Due diligence is the investigation of a commercial property’s physical condition and associated risks before purchase. It examines structural integrity, compliance with building codes (including NCC/BCA), tenancy arrangements, environmental hazards and anticipated repair costs, helping buyers avoid unexpected issues after purchase.

How long does a commercial due diligence report take?

Standard commercial inspection reports are typically delivered within three to seven business days of site access. The timeframe can vary with the size, condition and complexity of the property and the scope of the inspection.

What’s the difference between a commercial and residential inspection?

Commercial property inspections assess larger and more complex buildings, focusing on structural elements, building services, maintenance requirements and property-specific risks. Depending on the property, this may include HVAC, lifts, fire safety, access, OHS considerations and multi-tenant areas.

When should I arrange a commercial property inspection?

Commercial inspections are commonly arranged before purchasing or leasing a property, as part of due diligence, or when assessing an existing building’s condition and upcoming maintenance requirements.

How will the report help my purchase negotiations?

A commercial due diligence report documents defects, urgent issues, likely repair costs and compliance breaches. That evidence supports price renegotiation, requests for vendor rectification, adjustments to contract conditions or, if needed, withdrawal from the contract.

Does the report include estimated repair costs?

Yes. Our commercial property due diligence report includes cost estimates for remedial works on major defects. This may cover structure and other internal and external compliance issues, helping you quantify urgent repairs and future liabilities. For a detailed costing of works, see our construction cost reports.

Is the inspection disruptive to tenants?

We aim to keep our inspections minimally intrusive for tenants. Inspections focus mainly on visual checks, coordinated with property agents or business owners to minimise interruptions. Complex services such as HVAC or lifts may need brief access that affects tenants, and we make sure they are informed before the scheduled inspection.

Do I need a due diligence report before signing a commercial contract?

It is highly recommended during the contract’s due diligence period, often 30 to 90 days after agreement. Contracts typically include a “subject to satisfactory report” clause that allows termination or renegotiation if something is found to be unsatisfactory. If you don’t carry out due diligence beforehand, you risk losing protection under NSW “buyer beware” (caveat emptor) laws.
