If your commercial project in Perth needs an inspection, the first thing to understand is that it is usually not something the owner books directly like a standard service appointment. On most commercial jobs, inspections are built into the permit and construction process from the start. They are usually triggered when a particular stage of work is ready, and they are often coordinated by the builder, building surveyor, project manager, or another consultant involved in the project.
In other words, if you are asking “How do I request an inspection?”, the more practical question is usually: who on the project is responsible for arranging it, and what stage of work needs to be inspected before the project can move forward?
For most commercial projects in Perth, that responsibility sits with the project team rather than the owner. Commercial buildings generally go through the certified building permit pathway, which means a registered building surveyor is involved. According to the City of Perth and the Western Australian building approvals framework, a certified building permit application (BA1) must be used for commercial buildings (Class 2–9), and the permit may specify inspections, tests, or supporting certificates that are required before completion is recorded.

What this looks like in practice
On a live commercial project, an inspection is usually requested when a stage is ready and before the work is covered up or signed off as complete. That might happen after structural work, at a compliance stage, or when a specialist trade needs to certify part of the work. The builder or project manager will usually coordinate the timing with the surveyor, permit authority, or relevant consultant.
So, if you are the owner, tenant, or developer, you are often not the person making the request yourself. Instead, you should be checking that the builder or consultant team has allowed for those inspections in the programme and knows what must happen before the next stage begins.
How much notice should be given?
There is no single notice period that applies to every commercial inspection in Perth. The amount of notice depends on who is carrying out the inspection, what is being inspected, and how much preparation is required before the site is ready.
That is why inspection timing should be considered early, not left until the day the team wants sign-off. If an inspection is needed before the next stage can proceed, leaving it too late can hold up trades, create site downtime, or delay the programme. A better approach is to treat inspections as part of the construction schedule rather than something arranged reactively.
Does someone need to be onsite?
In most cases, yes. Someone responsible should be onsite when the inspection takes place so the inspector or surveyor can gain access, ask questions, and raise any issues immediately if needed. That does not necessarily mean the owner has to attend personally. More often, it will be the builder, site supervisor, project manager, or contract administrator.
The important point is that the right person is there, someone who understands the stage of work and can respond if clarification is needed.
How often do inspections happen?
There is no standard number of inspections for all commercial projects. A small fitout may only involve a limited number of formal checks, while a larger development may involve multiple staged inspections, specialist certifications, and signoffs throughout the build.
The frequency depends on the type of work, the permit conditions, and the level of compliance documentation required. In Western Australia, the building permit sets out the relevant inspections and tests, and the notice of completion must be accompanied by the applicable inspection certificates. That is why commercial inspections are better understood as part of a staged compliance process, not as a single final event near handover.

What should you do as the client?
If you are overseeing a commercial project in Perth, the most useful thing you can do is make sure inspection responsibility is clear early. You should know:
- who is responsible for arranging the required inspections,
- which stages are likely to require inspections,
- whether any work must be inspected before it is covered up,
- and how those inspections affect the construction programme.
Conclusion
On a commercial project, inspections are usually part of the broader permit and delivery process rather than a separate owner-led task. The request is typically coordinated through the builder, surveyor, or project team, and the timing needs to match the stage of work and the permit requirements.
