Building a home or starting a construction project is exciting—but it’s also a big responsibility. One of the most important parts of the process is building inspections.
These inspections are not just red tape. They protect you, your future property, and the people who will live or work there. They ensure that your building meets safety standards, local codes, and quality expectations.
If you’re in the early stages of construction or even just planning ahead, this guide will walk you through the main stages of building inspection so you know exactly what to expect.
1. Pre-Construction Inspection (Planning Stage)
Before you lay the first brick, a pre-construction inspection may be required. This usually involves reviewing your building plans and checking them against local regulations and zoning rules. The goal here is to:
- Make sure your plans comply with the law
- Avoid design mistakes that could cause issues later
- Prevent delays in getting permits
In some cases, engineers or building certifiers may be involved to evaluate the structural design. Getting expert input at this stage can save you from costly changes down the road.
2. Site Inspection (Before Work Begins)
Once your paperwork is approved and you’re ready to start, the inspector will visit your site to check a few key things:
- Soil condition and drainage
- Site boundaries and setback distances
- Access for emergency services
This inspection makes sure that your site is suitable for construction and that it won’t create problems for neighboring properties. If there’s any issue with water runoff or land stability, it needs to be handled before construction starts.
3. Footings and Slab Inspection
Next up is the footings inspection, which happens after the trenches are dug but before the concrete is poured. Inspectors will check:
- Footing depth and width
- Steel reinforcement placement
- Soil compaction
If your build includes a concrete slab, the inspector will also check the vapour barriers, insulation, and mesh placement before giving the green light to pour.
This stage is crucial. Mistakes in the footings or slab can lead to serious structural issues later on, like cracking or sinking floors. That’s why inspectors pay extra attention here.
4. Frame Inspection
Once the framework of the building is up—walls, roof trusses, beams—another inspection is needed. The frame inspection makes sure that:
- All structural elements are correctly installed
- The frame matches the approved plans
- Fixings and bracings are secure
- There’s proper allowance for insulation and services (plumbing, electrical)
This stage is often called the lock-up stage, because the house begins to take shape and can now be locked.
Framing is the skeleton of your building. If it’s off by even a little, it can throw off the entire structure. This is why this stage usually involves both a building inspector and a structural engineer.
5. Pre-Sheet Inspection (Wall and Ceiling Lining)
Before plasterboard or wall panels are installed, the pre-sheet inspection takes place. This is the chance to inspect what’s inside the walls—because once the walls are closed, it’s much harder to fix problems.
Inspectors look for:
- Proper placement of electrical and plumbing systems
- Structural bracing and fire-rated walls
- Insulation and soundproofing
- Moisture barriers in wet areas like bathrooms and kitchens
Any missing or incorrectly installed item must be fixed before moving on.
6. Waterproofing Inspection
Bathrooms, kitchens, and laundries all need proper waterproofing to prevent leaks and mold. In this stage, a certified waterproofer will apply the membrane and the inspector will check:
- Correct materials and thickness
- Full coverage in wet areas
- Drains, angles, and joints are sealed properly
Skipping this step or doing it poorly can lead to expensive repairs later. Water damage is a nightmare to fix—so don’t underestimate this inspection.
7. Fixing Stage Inspection
At the fixing stage, most internal components are installed: doors, windows, cabinetry, skirting, and architraves. The inspector checks that:
- Everything is installed according to the building plans
- Fixtures are straight and secure
- Internal walls haven’t been modified
- Fire safety and ventilation rules are followed
This inspection ensures that what’s inside the house is built to the same standard as the frame and foundations.
8. Final Inspection (Practical Completion Inspection)
This is the last inspection before you get your occupancy certificate. At this stage, the building should be 100% complete.
The inspector will check:
- Overall workmanship
- Safety systems (smoke detectors, balustrades, etc.)
- Plumbing and electrical compliance
- Functioning windows, doors, and ventilation
- Cleanliness and readiness for occupancy
Any minor issues (called “defects” or “snags”) will be listed in a final report. Your builder must fix these before you officially take possession of the property.
9. Post-Completion / Maintenance Period Inspection
Even after the final inspection, you may have a maintenance period (often 3-6 months) where you can report problems like:
- Cracked walls or ceilings
- Faulty installations
- Leaks or drainage issues
This stage isn’t mandatory, but it’s good practice—especially for newly built homes. Builders are usually obligated to fix any defects that appear within this period.
Why Building Inspections Matter
Every inspection stage plays a role in making sure your building is:
✅ Safe
✅ Structurally sound
✅ Compliant with the law
✅ Built to last
Skipping or rushing inspections can lead to dangerous outcomes, fines, or unexpected repair costs. Whether you’re building a new home, renovating, or extending, regular inspections protect your investment.
And remember: the earlier you catch a problem, the cheaper and easier it is to fix.
