Fastest Turnaround Times In The Surveying Industry!
Ensure your construction project meets council, certifier, and flood planning requirements.
When constructing a new home, secondary dwelling, commercial building, or addition in a regulated area, one of the most important compliance checks is whether the finished floor level meets the required minimum. This is especially critical in flood-prone zones, where failure to meet the minimum floor height can result in planning rejection, insurance issues, or the need for costly rework.
MCS Surveyors offer professional, certified floor level compliance surveys to confirm that your constructed floor slab or finished floor sits at or above the required level. Whether you are working under a Development Application (DA) or a Complying Development Certificate (CDC), we deliver precise measurements referenced to the Australian Height Datum (AHD), along with clear documentation ready for submission to councils, certifiers, or private assessors.
A floor level compliance survey is a post-construction check carried out by a registered land surveyor to confirm that the level of a slab, subfloor, or finished floor matches or exceeds the minimum required by council or regulatory planning controls. These controls often apply in flood-prone areas, bushfire zones, or sites where a minimum height above ground level is stipulated for habitable areas.
The survey involves measuring the actual level of the constructed floor and comparing it to the required Reduced Level (RL), typically referenced to AHD. It is a key part of ensuring the building has been constructed in accordance with approved plans, and it is commonly required to obtain final approval, occupancy certification, or compliance with a CDC.
This type of survey is typically carried out:
For homeowners, builders, and project managers, confirming floor level compliance early can avoid significant cost and delay later in the build.

All measurements are conducted to a high degree of accuracy and are suitable for use in residential, commercial, and government approvals.
Our process is designed to be quick, non-intrusive, and compliant with industry best practice. It includes the following steps:
We review the approved development plans, CDC or DA documents, and flood planning levels relevant to your site. This allows us to determine the benchmark RL against which your floor must be measured.
Our survey team visits the site and uses total station and GNSS technology to measure the floor level. This is done by referencing a Permanent Survey Mark (PSM) or known datum nearby, ensuring the result is tied to the Australian Height Datum.
We compare the measured RL of the floor with the required minimum and prepare a clear report outlining whether the level is compliant. Any variations or issues are flagged immediately.
We provide you with a signed survey plan and compliance statement, in both PDF and CAD formats, suitable for submission to private certifiers, councils, or planning consultants.
We also offer fast-tracked reporting where required to assist with time-sensitive approvals or inspections.
