Driveway technical standards | Brisbane City Council

Driveway technical standards

Gradients

Driveways must not exceed the maximum gradient level of one in four inside the property boundary and one in six outside the property boundary. The rate of change in a driveway gradient is a maximum of one in 12 slope for a minimum length of one metre. Recommended gradients are set out in Brisbane City Council’s standard drawings (refer to BSD-2024 and BSD-2025).

If the cross fall of a driveway is severe and embankments are steeper than one in four, retaining walls may be required. Refer to Part 4.0 Steep Lots in Council's Subdivision and Development Guidelines Part B Chapter 6 Vehicular Property Access.

To find out the maximum fall per metre, select your proposed grade from the list.
