How Long Does a Building Inspection Take in Perth? Complete Guide

 

G'day! As a local building inspector here in Perth, I get asked this question almost daily: "How long does a building inspection take?" It's totally understandable – you're trying to plan your day, maybe taking time off work, or coordinating with real estate agents. After 15 years of crawling through homes, I can honestly say there's no one-size-fits-all answer.

The short answer? Most building inspections take between 1.5 to 3 hours. But I’ve seen quick 1-hour inspections for small units, and I’ve spent an entire day on sprawling heritage homes in suburbs like Fremantle.

Let me walk you through what actually determines how long your building inspection will take, because understanding this will help you plan better and get more value from your inspection.


What Exactly Am I Looking For During Your Building Inspection?

Before we dive into timing, let me explain what happens during a building inspection. Think of me as a detective with a clipboard and a torch. I'm checking every nook and cranny of your property to spot issues that could cost you thousands down the track.

I'll be examining your roof (yes, I actually climb up there!), checking structural elements, testing electrical appliances, inspecting water leaks, looking for pests, and much more. It's like giving your house a comprehensive health check. See a full list of what’s covered in a Perth building inspection.


How Long Will Your Building Inspection Actually Take?

Here's where I get specific about timing, based on what I see daily in Perth suburbs:

Age of Your Home

  • Common in areas like East Perth and South Perth, these compact spaces are quicker to inspect due to fewer rooms. Still, inspectors check all key areas like moisture levels and internal finishes thoroughly.

  • Typical in suburbs like Morley and Balcatta, these homes allow for a full internal and external inspection without being too time-consuming. Roof voids and subfloors (if accessible) are usually included

  • Found in areas like Dalkeith or Mount Pleasant, these homes have more rooms, bigger roof areas, and features like pools or granny flats. That adds inspection time due to the extra elements involved.

  • Common in estates like Ellenbrook and Alkimos, two-storey properties take longer due to extra levels, staircases, and upper roof zones that require more time and care to inspect safely.

Specific Property Challenges

Living in Perth, you'll know we have everything from 1950s weatherboard homes to brand new builds in Ellenbrook. This affects timing significantly:

  • Older Perth homes (pre-1980s)
    These beauties take longer because there's usually more to find. They're gorgeous, but I need extra time to check for asbestos, plumbing leaks, and structural settling.

  • Modern homes (post-2000)
    Generally quicker inspections as everything's more accessible and built to current standards. Usually straightforward.

  • Heritage properties
    If you're looking at one of the heritage gems, block out a full day. These require special attention and often reveal fascinating (and expensive) surprises.


Factors Affecting Inspection Time

Let me share some real examples from my Perth inspections:

  1. Locked or Blocked Roof Voids
    Accessing the roof space (ceiling cavity) is crucial for checking insulation, structural framing, and signs of leaks or pests. If the manhole is locked, covered with furniture, or built too small, the inspector may be unable to assess it properly.

  2. Inaccessible Subfloors
    For homes with timber floors, the subfloor area needs inspection for moisture issues, structural damage, or termite activity. If it's too low, sealed off, or filled with stored items, it becomes impossible to inspect safely.

  3. No Access to Garage or Shed
    Detached garages, workshops, or garden sheds can hide issues like structural movement, roof leaks, or termite damage. If the keys aren't available or the areas are cluttered, these spaces may be skipped or only partially inspected.

  4. Overgrown Vegetation or Debris
    Heavy vegetation, rubbish, or garden beds built up around the house can block visual access to external walls, weep holes, and slab edges – all of which are key inspection points for water ingress or termite entry.

  5. Tenanted or Occupied Homes
    If tenants or owners aren’t informed in advance, inspectors may not be allowed into certain rooms, especially bedrooms, attics, or storage spaces. This lack of full access can limit the report’s accuracy and completeness.


Perth's Unique Challenges

Our Perth climate and building styles create specific timing considerations:

  1. Double Brick Construction
    Perth homes are predominantly built with double brick, which can hide cracks, moisture ingress, or structural movement within wall cavities. Inspectors often take extra time to assess internal and external wall alignment and use moisture meters more thoroughly.

  2. Expansive Clay Soils (Especially in Northern Suburbs)
    Many Perth suburbs – especially in the north – are built on reactive clay soils that expand and contract with moisture. This causes slab movement, wall cracks, and uneven floors, requiring a more detailed structural assessment during the inspection.

  3. Coastal Corrosion
    Properties near coastal areas like Fremantle, Cottesloe, or Rockingham are prone to salt-induced corrosion of metal fixtures, roof sheets, and structural elements. Inspectors must carefully check for early signs of rust and deterioration, which adds time.

  4. High Risk of Termite Activity
    Due to Perth’s warm climate and widespread use of timber framing in extensions or older homes, termite inspections require extra attention—especially around garden beds, subfloors, and fence lines, which are common termite entry points.

  5. Poor Renovation Practices
    Perth has seen a boom in DIY and budget renovations. Inspectors often need to investigate non-compliant extensions, poorly waterproofed wet areas, or hidden structural alterations—especially in older suburbs like Victoria Park or Mount Lawley.

Weather-Related Factors

  • Heavy Rain
    Most critical factor. Makes roof access unsafe, floods subfloors, and interferes with moisture detection tools. Can obscure leaks or make it difficult to tell if water ingress is active or historic.

  • Extreme Heat (Summer Roof Voids)
    Perth summers can make roof spaces dangerously hot (50°C+), limiting time inspectors can safely spend inside. Often results in partial inspections or revisits for complete assessment.

  • Strong Winds
    Prevents safe use of ladders and roof access, particularly for metal or tiled roofs. Can lead to rescheduling of external or roof inspections.

Other factors like humidity or morning dew are minor in Perth, unless the inspection is first thing in winter. They're less likely to delay the inspection but may affect certain readings (like moisture levels).


Tips to Ensure an Efficient Inspection

After thousands of Perth inspections, here's how you can help the process run smoothly:

Before the Inspector Arrives:

  • Clear the path: I need access to your roof manhole, electrical box, hot water system, and around the house perimeter.

  • Turn everything on: Power, water, gas – I need to test all systems.

  • Gather your paperwork: Previous inspection reports, renovation permits, or warranty documents help me focus on known issues.

During the Inspection:

  • Stick around: I encourage clients to follow me around (safely). Ask questions!

  • Take notes: Write down issues or tips I point out.

  • Don't rush me: Thorough inspections take time. Rushing leads to missed issues.

  • Same day: I'll give you a verbal summary of major findings immediately after inspection.

  • Within 24 hours: You'll receive my comprehensive written report with photos, detailed findings, and recommendations.

  • Rush jobs: Available for urgent situations, but I prefer the standard timeline to ensure thoroughness.

What's in Your Report:

  • Detailed findings with photos

  • Priority ratings for issues found

  • Maintenance recommendations

  • Cost estimates were appropriate

  • Explanations in plain English (no confusing jargon!)


Making the Most of Your Investment

During the Inspection:

  • Ask about maintenance schedules

  • Learn how your home's systems work

  • Understand which issues are urgent vs. long-term

  • Get tips for preventing future problems

After Receiving Your Report:

  • Read everything, not just the summary

  • Use the report for maintenance planning


The Bottom Line from Your Local Perth Inspector

So, how long does a building inspection take? For most Perth homes, plan on 1.5–3 hours for a thorough job. But remember, I'd rather take an extra hour and find that hidden termite damage than rush through and miss something that could cost you $20,000 later.

I've been inspecting Perth homes since 2008. Every property tells a story, and my job is to read that story for you. Some stories are quick reads, others are epic novels that require patience and attention to detail.
