If you are contemplating the purchase of a charming 1970s brick-and-tile home in the inner suburbs, or a modern property in one of Brisbane’s rapidly developing areas, obtaining a pre-purchase inspection is vital. The inspector's focus will shift considerably depending on the age of the property, as this significantly impacts the potential issues that could arise.
Quick Overview: For older residences, a pre-purchase inspection aims to uncover age-related problems, including structural movement, past repairs, outdated electrical and plumbing systems, and evidence of termite activity. In contrast, inspections for new constructions focus on the standard of workmanship, highlighting any defects or shortcuts that may have been taken during the building process. Both inspection types adhere to the Australian Standard (AS 4349.1), but the inspector's focus will change based on the property's age.
At Zoom Building & Pest Inspections, we conduct evaluations for both older and new properties as a QBCC-licensed firm (QBCC licence 15279880) catering to Brisbane and the Moreton Bay region. Below, we detail the primary distinctions between these two types of inspections.

Key Inspection Focus Areas for Older Properties
Older properties come with a distinct history, often hiding unexpected and costly surprises. A building inspection for an established home prioritises the impacts of time and any renovations or repairs that have been made over the years:
- Structural Movement — Problems such as cracking, uneven floors, and concerns with foundations and subfloors that may develop over decades.
- Roof Condition — Deterioration of roof tiles or metal, compromised flashing, and repairs that have been superficially addressed rather than properly fixed.
- Outdated Services — Ageing electrical and plumbing systems that may be nearing the end of their lifespan.
- Moisture and Drainage — Issues like rising damp, poor drainage, and water accumulation in unsuitable areas.
- Termite History — Previous damage and conditions that may promote termite infestations, often associated with older timber structures and well-established gardens.
Essential Inspection Checks for New Constructions
A newly built home is generally expected to be free of defects; however, many do not meet this expectation. The inspection for a new build focuses on the quality of workmanship and the overall completion rather than age, revealing common mistakes that can occur on busy construction sites:
- Finishing Defects — Issues related to tiling, painting, gaps, and trades’ work that have not been completed to a satisfactory standard.
- Waterproofing — Evaluating wet areas and balconies, where shortcuts may lead to leaks within a year or two.
- Roof and Drainage — Problems such as loose tiles and poorly installed gutters and downpipes that do not drain effectively.
- Incomplete Work — Tasks that remain unfinished at the time of handover, requiring follow-up after moving in.

Maintaining Consistent Standards with Varied Inspection Focus
Both types of inspections are carried out according to AS 4349.1, the Australian Standard for pre-purchase building inspections. This standard mandates a thorough visual assessment of the property's condition. The key difference lies in focus: for older homes, the emphasis is on evaluating aging and past renovations, whereas for new builds, we concentrate on quality and completion. In either scenario, you will receive an independent report detailing the actual condition of the property you are considering.
Why a Pest Inspection is Crucial
In Brisbane, securing a pest inspection is advisable, regardless of the property's age. Subterranean termites are common in the area, and new constructions are not immune to their threats. Factors such as newly landscaped areas, slab edges, and garden beds adjacent to the home can foster conditions favourable for termite infestations. A combined building and pest inspection provides a comprehensive overview of both the property's condition and potential timber pest risks, all in a single visit. If you're uncertain, consider which inspection is most relevant to your situation.
