Height and certification surveys confirm that building structures meet vertical height limits and setback requirements, often required for council sign-off or final building certification.
At Sonto, we provide fast, accurate surveys to support Form 12 certification for height and location. Whether it’s slab level, ridge height or boundary setback, we work with builders, certifiers and engineers to verify compliance and keep your project moving forward.
We clarify whether the survey is needed for slab level, ridge height or setback to boundaries, then align with the Aspect Inspection Form 12 requirements.
We attend site and capture precise data for heights and structure locations using calibrated survey total stations.
We assess field data against approved plans and boundaries to confirm compliance with vertical limits, setbacks and envelope conditions.
We provide a certified Form 12 for submission to your building certifier, council or approval authority.

We liaise with your certifier or builder to understand the Form 12 requirements: roof height, slab level, setbacks, or a mix of all three.
Our team visits the site and records all required data with high-accuracy instruments, keeping your build on track and compliant.
We assess field data against approved plans, boundaries and height restrictions, confirming whether built structures meet the approval conditions.
We prepare a signed survey plan and Form 12, ready for submission to your certifier or council for final compliance.
A Form 12 is a surveyor’s certificate confirming that specific building elements (like height or setback) comply with approved plans. It’s often required for council sign-off, final building approval, or when there’s a risk of encroaching height or setback limits.
Yes. We can certify heights during or after construction whether you’re checking a slab before framing or confirming ridge heights after roof completion. The earlier you engage us, the better for avoiding costly rework.
Absolutely. We measure the position of walls, eaves or structures relative to title boundaries and confirm if they meet setback or encroachment requirements. This is a common Form 12 use case.
In most cases, we can attend site within 3-4 business days and issue the Form 12 within a few days of survey, depending on the scope. We move quickly to avoid holding up your approvals.
Not always. If we identify a non-conformance, we may be unable to issue a compliant Form 12. In these cases, we can issue an ASCON plan or letter reflecting the site data for assessment by your certifier, who will advise on next steps.
