If you’re considering building a granny flat in Melbourne, one of the first questions you’re likely to ask is:
“How much access do I need to build a granny flat on my property?”
Many homeowners assume they need a wide driveway, a corner block or several metres of side access before a granny flat becomes possible. In reality, Victoria’s Small Second Dwelling regulations are far more flexible than many people realise.
At Orlando Homes, access concerns are one of the most common reasons homeowners initially believe they cannot build a granny flat. After assessing sites throughout Melbourne’s south-east and the Mornington Peninsula, we’ve found that many seemingly challenging blocks can still accommodate a secondary dwelling with the right design and construction approach.
Whether you’re researching granny flat requirements in Victoria, wondering “Can I build a granny flat on my block?”, or simply trying to understand how much side access is needed, understanding access requirements is an important place to start.
The Short Answer
Under Victoria’s Small Second Dwelling regulations, a compliant access path must be provided from the front street to the secondary dwelling.
The path must:
These requirements are contained within Regulation 86B – Accessibility for Small Second Dwellings.
For many Melbourne homeowners, this comes as a surprise because the legal access requirement is often much smaller than they expected.
Access Width vs Construction Access
One of the biggest misconceptions surrounding granny flats in Victoria is that the legal access requirement is the same as the access required to build the dwelling.
These are actually two very different things.
Regulatory Access
Victoria’s Small Second Dwelling regulations require a compliant pathway that allows safe and practical access to the dwelling once construction is complete.
In many situations, a pathway as narrow as 1 metre can satisfy the accessibility requirements.
Construction Access
Construction access relates to how your granny flat builder physically gets materials, trades and equipment into the backyard during construction.
Factors that can influence construction access include:
This means a property may satisfy the regulatory access requirements while still requiring a tailored construction solution.
At Orlando Homes, every granny flat site assessment considers both regulatory compliance and practical construction feasibility.
Can I Build a Granny Flat on My Block?
While access is an important consideration, it is only one of several factors that determine whether a property is suitable for a granny flat or small second dwelling.
At Orlando Homes, we’ve assessed sites across Frankston, Mount Eliza, Mount Martha, Mornington, Berwick and throughout Melbourne’s south-east. Many homeowners initially assume their block is unsuitable due to narrow access, established trees, retaining walls or site slope.
In reality, a professional site assessment looks at the complete picture, including:
Many properties that appear challenging at first glance can still accommodate a granny flat through thoughtful design and construction planning.
The best way to understand the true potential of your property is through a professional site assessment.
Real Melbourne Granny Flat Examples
Every site is different, which is why access should never be assessed on width alone.
Frankston Granny Flat Site Assessment
A recent Orlando Homes client in Frankston had suitable access to accommodate a secondary dwelling, however several mature trees located within the backyard required consideration during the planning process.
Rather than becoming a barrier to development, the discussion focused on identifying the most appropriate construction approach. Options included selective tree removal or utilising specialised construction methods and equipment to work around the existing vegetation.
The project highlighted the importance of assessing the entire site rather than focusing on a single constraint. In many cases, there are multiple pathways available to achieve a successful outcome.
Mount Martha Granny Flat Project
A recent Orlando Homes client in Mount Martha had already selected a preferred granny flat design and wanted to understand whether the site could accommodate the proposal.
Fortunately, the property benefited from a unique corner lot configuration that provided excellent access to the proposed building area and simplified the construction process.
Rather than access being a constraint, the site’s layout became a key advantage, allowing the project to progress efficiently through the feasibility and design stages.
This project highlights that while access is an important consideration when building a granny flat in Melbourne, some properties naturally provide favourable conditions that can reduce complexity and improve construction efficiency.
While every property is different, we’ve found access considerations vary significantly across Melbourne’s established suburbs. Narrow side setbacks are common in areas such as Mount Eliza and Berwick, while sloping blocks are frequently encountered throughout the Mornington Peninsula.
Can I Build a Granny Flat If I Have No Side Access?
Even if your property has little or no traditional side access, there may still be options available.
Depending on the site, solutions can include:
Every property presents different opportunities and constraints.
This is why choosing an experienced granny flat builder in Melbourne is critical during the feasibility stage.
Victorian Planning Reforms Have Changed the Rules
Victoria’s Small Second Dwelling reforms have made it easier for many homeowners to add a granny flat to their property without the lengthy planning processes that were previously required.
In many residential zones, a compliant Small Second Dwelling of up to 60m² can be constructed without a planning permit, subject to zoning, overlays and compliance with the applicable provisions.
As a result, many homeowners who previously assumed a granny flat wasn’t possible are now revisiting the opportunity.
This has created significant opportunities for:
As a result, more Melbourne homeowners are exploring whether they can build a granny flat on their existing block.
Common Access Scenarios We See Across Melbourne
While every property is different, several access scenarios commonly arise during granny flat site assessments.
Narrow Side Access
Many homeowners believe side access under two metres automatically rules out a granny flat. In reality, the relevant consideration is whether a compliant access path can ultimately be achieved and whether construction can be completed safely and efficiently.
Corner Blocks
Corner blocks often provide additional flexibility by allowing access from a secondary street frontage. This can simplify construction and create greater design freedom.
Sloping Sites
Sloping blocks may require retaining walls, specialised engineering or modified construction techniques. However, they are often still suitable for a small second dwelling.
Established Landscaping
Mature trees, garden beds and existing outdoor structures can influence construction methodology but do not necessarily prevent development.
Every site presents a unique combination of opportunities and constraints, which is why a professional feasibility assessment is essential.
Which Granny Flat Design Works Best on Your Block?
If you’re still determining whether your property is suitable, our guide, “Can I Build a Granny Flat on My Block? A Melbourne Site Assessment Checklist” explains the key site assessment factors we review before recommending a design.
Many homeowners begin by asking how much backyard space or access they need, but the better question is often:
“Which granny flat design best suits my property?”
While access is an important consideration, factors such as site slope, easements, service connections, retaining walls and the location of the existing home often play a greater role in determining whether a granny flat can be delivered efficiently and cost-effectively.
This is why Orlando Homes undertakes a detailed site assessment and due diligence process before finalising construction pricing. Rather than simply determining whether a granny flat fits on the block, we assess whether it can be delivered efficiently, compliantly and cost-effectively.
Our assessment includes reviewing:
By identifying potential challenges early, we can provide greater certainty throughout the design, approval and construction process while recommending the most suitable granny flat for your property and objectives.
Popular Orlando Homes designs include:
Toronto 25
A compact one-bedroom design ideally suited to smaller backyards, ageing parents, adult children or investment-focused projects.
Whistler 45
A spacious one-bedroom design that provides increased living space while maintaining a relatively compact footprint.
Montreal 60
A practical two-bedroom design that balances functionality, rental appeal and efficient site utilisation.
Vancouver 60

Ultimately, the most suitable granny flat is not determined by backyard size alone. Access, site conditions, services, planning requirements and your long-term goals all influence which design will deliver the best outcome.
Frequently Asked Questions
How much side access do I need for a granny flat in Victoria?
Under Victoria’s Small Second Dwelling regulations, a compliant access path must generally be at least 1 metre wide, increasing to 1.8 metres where the access path exceeds 30 metres in length. The path must also meet minimum height, gradient and accessibility requirements under Regulation 86B.
Can a granny flat be built with less than 2 metres of side access?
Potentially, yes. Every property is different. While a compliant access path must ultimately be provided, construction methods can vary depending on site conditions. A professional site assessment can determine what options may be available.
Do I need vehicle access to build a granny flat?
No. Many granny flats and small second dwellings are successfully constructed without direct vehicle access to the backyard. Depending on the site, builders may utilise alternative construction methods, specialised equipment or staged material handling solutions.
Can I build a granny flat on a corner block?
Yes. Corner blocks can often provide additional flexibility by allowing access from a secondary street frontage. This can simplify construction and create greater design opportunities, although the dwelling must still comply with all applicable regulations.
What if there are trees where I want to build?
Existing trees do not automatically prevent a granny flat from being constructed. Factors such as the tree species, location, root protection requirements and proposed building footprint all need to be assessed. In many cases, design adjustments or alternative construction approaches can be explored.
Does Victoria require a planning permit for a granny flat?
In many residential zones, a compliant Small Second Dwelling of up to 60m² can be constructed without a planning permit, subject to zoning, overlays and compliance with the applicable provisions. A building permit is still required.
How do I know if my block is suitable for a granny flat?
The best way is through a professional site assessment. Access, available backyard space, easements, services, zoning, site slope and the location of the existing home can all influence whether a granny flat is feasible.
What is the difference between access requirements and construction access?
Access requirements relate to the pathway needed to comply with Victoria’s Small Second Dwelling regulations once the project is complete. Construction access refers to how materials, trades and equipment are moved to the building area during construction. A property may satisfy regulatory access requirements while still requiring a tailored construction approach.
