Submit an application to do exploratory excavation works, construct retaining walls, or build a driveway prior to a Building Permit only.
A site alteration permit is required prior to any site works. Use this application if your site conditions require some preliminary site work in advance of a Building Permit.
This typically means you have a bare lot and want to prepare the site in advance of starting construction of a home.
For further clarification, please follow the steps for contractors and architects.
Types of work permitted
The four specific types of work allowed with this type of permit are:
- Exploratory site grubbing works
This typically means that you plan to clear the site within your building envelope to understand the geotechnical conditions of your site that will determine how you will build on your site.
- Construction of retaining walls
This typically means that you plan to build retaining walls to establish suitable site conditions to build on your site.
- Establishment of a driveway
This typically means that you have a challenging site and need to create access in order to build on your site.
- Installation of site services
This typically means that you plan to install site servicing for future construction. Note that site servicing installed under a Site Alteration permit must be undertaken by an Engineer.
The scope of work allowed under this type of application are limited. Structural works are specifically not permitted.
