Understanding Victoria's Building Regulations for Foundations
Victoria’s building regulations around foundations can feel like a maze of standards and permit processes. Here’s a plain-English overview of how it all fits together.
The Regulatory Framework
Foundation and slab work in Victoria sits within a broader regulatory framework combining the National Construction Code, relevant Australian Standards (particularly AS 2870 for residential slabs and footings), and Victoria-specific building regulations administered through the building permit system.
AS 2870 and Technical Standards
AS 2870 is the primary technical standard governing residential slab and footing design — establishing the site classification system and design requirements that engineers work within. This is the technical backbone referenced throughout foundation engineering, regardless of which specific slab system is ultimately specified.
Building Permits
Compliant foundation work requires a building permit, issued based on certified engineering documentation. See our guide to building permits for concrete slabs for the specific process this involves.
The Role of Building Surveyors
Registered building surveyors — private or council-based — administer the building permit process, reviewing engineering documentation and carrying out required inspections. See our guide to what building surveyors check for more on their specific role.
Council and Planning Overlap
Beyond building regulations specifically, some foundation and site works can intersect with planning requirements — particularly for excavation near boundaries, heritage-affected properties, or significant earthworks. Understanding where building regulations end and planning considerations begin helps set realistic expectations for your project’s approval pathway.

Frequently Asked Questions
What's the main technical standard for residential foundations in Victoria?
AS 2870, which establishes the site classification system and design requirements for residential slabs and footings.
Do all foundation projects need a building permit in Victoria?
New house slabs always do; other foundation work depends on specific scope — worth confirming with a building surveyor for your specific project.
Who administers building permits for foundation work?
Registered building surveyors, either privately engaged or through your local council.
Is planning approval the same as a building permit?
No — they’re separate processes, though some projects (particularly near boundaries or in heritage areas) can require both.
Where can I get clarity on my specific project's regulatory requirements?
A building surveyor is the reliable source for confirming your specific project’s permit and compliance requirements.
