Building Permits and Part 4 of the Building Regulations 2006 (ie. ResCode)

When making an application to a Building Surveyor for approval of a proposed development, it is the responsibility of this Relevant Building Surveyor to determine whether a Town Planning Permit is required from the local Municipal Council. Local Council’s have guidelines in relation to the various types of building Classes/Types/Zones allowed within their municipal boundaries. Planning Scheme Overlays and Zones determine whether the local Council requires involvement in the approval process. If a property to be developed (ie. external building works or change of a building use) is under an Overlay or specific Zone (ie. non-Residential 1 Zones) it generally requires the approval of the local Council Planning Department, in the form of a ‘Town Planning Permit’.

The documentation to be submitted when applying for a Building Permit, where a Planning Permit is also required, must incorporate a copy of the relevant Planning Permit and the endorsed documentation. Throughout the Building Permit process and construction work, the Building Permit and Planning Permit documentation must remain consistent, within reason. Meaning, if a change (Architectural) is made to the construction issue drawings, it must be approved by the Relevant Planning Authority before it can be made a Building Permit amendment.

When it is determined by the local Council and the Relevant Building Surveyor that a Planning Permit is not applicable for a proposed development, generally being one Dwelling on a single allotment or associated works, residential Siting is to be in accordance with Part 4 of the Building Regulations 2006 (ie. ResCode). It is then the role of the Relevant Building Surveyor to ensure that the design documentation submitted for the Building Permit application complies with these Regulations.

ResCode applies to all residential Building Permit applications. ‘ResCode’ brings all the objectives and standards for housing together into two regulatory documents – being local Council Planning Scheme’s and Part 4 of the Building Regulations 2006.

The following are regulated under Part 4 of the Building Regulations 2006 (ResCode):
- wall, fence and carport heights
- wall, fence and carport lengths
- boundary setbacks
- private open space - including secluded private open space site coverage
- light courts to habitable room windows of the subject building
- light courts to habitable room windows of an adjoining residence
- overlooking
- overshadowing
- obstruction of solar access to north facing windows of adjoining residences
- off-street car parking
- amount of allotment covered with surfaces impervious to soakage of rainwater.

Designs not in compliance with the prescribed measures cannot be granted a Building Permit, unless the local Council consents to the alternative non-complying design (ie. Dispensations).

Design Considerations - Dispensations/Report and Consent(s)

The local Municipal Building Surveyor is the delegated responsible officer for making a decision in regards to an application for Dispensation/Report and Consent.


It is usually recommended that your nominated Relevant Building Surveyor complete a ResCode assessment of your proposal in order to determine the ResCode Clauses requiring a Report & Consent / Dispensation from a Council.


When do the Building Regulations apply?
Part 4 of the Building Regulations applies to the construction or extension of one Dwelling, as outlined in the following table. Planning Permits are required in all other cases.

Type of Development Requirements

Single Dwellings requiring only a Building Permit

If the site is greater than 300m2 or 500m2 and is not covered by an overlay in the Planning Scheme, then only a Building Permit is required.

Applications will be assessed against the standards outlined within the Building Regulations and if a proposal does not meet any of these requirements, then approval is required from the Council's Municipal Building Surveyor.
Single Dwellings requiring a Planning Permit If the site is greater than 300m2 or 500m2 and/or is not covered by an Overlay in the Planning Scheme, that incurs the need for Town Planning approval, then only a Building Permit is required.
Multi Dwellings requiring a Planning Permit Any proposal for more than one Dwelling on a site will continue to require a Planning Permit and will be assessed against Clause 55 of the Planning Scheme.
