Building finance in Australia operates within a framework of regulations designed to protect both lenders and borrowers. These rules determine how much you can borrow, when funds are released, who can access finance, and what documentation your lender requires before releasing each progress payment.
Fixed Price Building Contracts and Lender Requirements
Most lenders will only approve construction finance when you have a fixed price building contract with a registered builder. This contract locks in the total build cost and provides the lender with certainty about the final loan amount. Without a fixed price agreement, lenders cannot accurately assess the risk or determine how much to approve.
Consider a borrower planning a custom design home on a subdivided block in Brunswick East. They approach their bank with a cost plus contract, where the builder charges for materials and labour with a margin added. The lender declines the application. The borrower then engages a registered builder who provides a fixed price contract for the same build. The same lender approves the loan within a week.
The difference is regulatory certainty. Fixed price contracts reduce the risk of cost blowouts that leave borrowers unable to complete the build. Lenders structure their approval criteria around this requirement, and most will not consider alternative arrangements unless you are an owner builder with substantial equity.
Owner Builder Finance and Additional Compliance
Owner builder finance is available, but it comes with stricter requirements. Lenders treat owner builders as higher risk because the borrower is responsible for project management, hiring sub-contractors like plumbers and electricians, and ensuring quality construction. To offset this risk, lenders typically require a larger deposit, often 20% to 30%, and may impose higher interest rates.
You will also need to provide detailed council plans, a comprehensive budget showing how funds will be allocated across each stage, and evidence of your capacity to manage the build. Some lenders require proof of relevant building experience or that you have engaged a project manager. The regulatory framework around owner builder finance reflects the increased likelihood of delays, cost overruns, or incomplete projects.
Progressive Drawdown and the Role of Inspection
Construction loans operate on a progressive drawdown model. Funds are released in instalments as the build reaches specific milestones, such as slab completion, frame stage, lock-up, and practical completion. Before each drawdown, the lender arranges a progress inspection to verify that the stage is complete and the work meets the required standard.
This process is regulated to ensure that funds are only released when the work justifies the payment. Lenders typically charge a Progressive Drawing Fee, sometimes called a Progressive Payment Fee, to cover the cost of these inspections. The fee is usually between $300 and $600 per inspection, and there are typically four to six inspections across a standard residential build.
The inspection requirement protects both parties. For the lender, it confirms that their security is being built as planned. For the borrower, it provides independent verification that each stage is complete before the builder receives payment. The progress payment schedule in your building contract should align with the lender's drawdown stages to avoid delays or disputes.
Development Application and Council Approval Timing
You cannot draw down construction funds until you have received council approval and all relevant permits. This regulatory requirement means that even if your loan is formally approved, the funds remain unavailable until your development application is finalised. In Brunswick East, which falls under the Moreland City Council, approval times can vary depending on the complexity of the build and whether your design complies with local planning overlays.
Most construction loan approvals require you to commence building within a set period from the Disclosure Date, typically six to twelve months. If council approval is delayed beyond this window, your loan approval may lapse and you will need to reapply. The regulations around timing are strict because lenders price construction loans based on the assumption that the build will commence and complete within a predictable timeframe.
Interest Only Repayments During Construction
During the construction phase, most lenders offer interest-only repayment options. You only pay interest on the amount drawn down, not the full approved loan amount. This regulatory structure recognises that you are likely paying rent or another mortgage while the build is underway, and cannot afford to service the full loan until you move in.
Once construction is complete and the loan converts to a standard home loan, you begin making principal and interest repayments. Some lenders offer a construction to permanent loan, where the transition happens automatically. Others require you to refinance or reapply once the build is finished. The terms are governed by your loan agreement, and the regulatory framework ensures that lenders clearly disclose how and when the loan will convert.
Land and Construction Packages Versus Standalone Building Loans
If you are purchasing suitable land and building on it, you may structure the finance as a land and construction package or as two separate loans. A land and build loan allows you to borrow for both the land purchase and the build under a single approval, which can reduce costs and simplify the process.
Regulations require lenders to assess your capacity to service the full loan amount from the outset, even though construction may not commence for several months. This can affect how much you are approved to borrow, particularly if you need to service the land loan while waiting for council plans to be finalised or for the registered builder to start work.
In Brunswick East, where land supply is limited and sites are often subdivisions or redevelopments, lenders pay close attention to whether the land is zoned for residential construction and whether any easements or covenants restrict the build. These regulatory checks are completed during the loan assessment and can delay approval if issues arise.
Renovation Finance and Partial Construction Rules
A house renovation loan operates under similar regulatory requirements to new home construction finance, but with some differences. If the renovation involves structural work, such as an extension or a second storey, lenders will require council approval, a fixed price contract, and a progress payment schedule. If the work is cosmetic, such as kitchen or bathroom upgrades, some lenders will approve the finance as a home improvement loan without requiring progressive drawdowns.
The distinction is important because it affects the interest rate, the fees you pay, and the documentation required. Lenders regulate renovation finance more strictly when the work affects the structural integrity of the property, as this changes the risk profile of their security.
Off the Plan Finance and Presale Requirements
Off the plan finance is a specific category of construction loan used when purchasing a property that has not yet been built, such as an apartment in a new development. Regulations require lenders to approve the loan based on the plans and the contract, but the loan does not settle until the build is complete and the title is registered.
This introduces additional regulatory requirements around sunset clauses, which allow either party to exit the contract if the build is not complete by a specified date. Lenders must also reassess your borrowing capacity and the property value at settlement, which can be months or years after the initial approval. If your circumstances change or the market shifts, the lender may reduce the approved loan amount or decline to settle.
These rules are designed to protect borrowers from being locked into contracts for properties that may not be completed or may be worth less than the purchase price when the title is finally registered.
Regulatory Limits on Loan to Value Ratios
Construction loans are subject to the same loan to value ratio regulations as standard home loans, but lenders often apply more conservative limits. For new home construction finance, most lenders will lend up to 90% of the combined land and build cost if you meet their criteria, but many prefer to cap construction lending at 80% to reduce exposure.
If you are building a spec home with the intention to sell on completion, lenders apply even stricter limits, often requiring 30% to 40% equity. Spec home finance is considered higher risk because the lender cannot rely on your income to service the loan if the property does not sell quickly.
These regulatory settings reflect broader prudential requirements imposed by the Australian Prudential Regulation Authority, which requires lenders to manage their exposure to construction lending and ensure that borrowers can service the debt.
How Documentation Requirements Protect All Parties
Every construction loan application requires extensive documentation, including the fixed price building contract, council approval, proof of deposit, evidence of income, and details of any sub-contractors involved in the build. Lenders use this documentation to assess whether the build is viable, whether the borrower can afford the repayments, and whether the completed property will provide adequate security.
These regulatory requirements can feel onerous, but they reduce the risk of disputes, cost blowouts, and incomplete builds. In our experience, borrowers who engage with the documentation process early and work with their builder to ensure all paperwork is accurate and complete are far more likely to have their loan approved quickly and to experience a smooth drawdown process.

Frequently Asked Questions
Do I need a fixed price building contract to get construction finance?
Yes, most lenders require a fixed price building contract with a registered builder before approving construction finance. This contract provides certainty about the total build cost and reduces the risk of cost overruns that could leave the project incomplete.
How do progressive drawdowns work during construction?
Funds are released in instalments as your build reaches specific milestones, such as slab completion, frame stage, and lock-up. Before each drawdown, the lender arranges a progress inspection to verify the work is complete and meets the required standard.
Can I get construction finance if I am building as an owner builder?
Owner builder finance is available but comes with stricter requirements, including a larger deposit (typically 20% to 30%) and detailed documentation showing your capacity to manage the build. Lenders treat owner builders as higher risk due to the increased likelihood of delays or cost overruns.
What happens if my council approval is delayed?
You cannot draw down construction funds until you have council approval and all relevant permits. If approval is delayed beyond the timeframe specified in your loan approval (typically six to twelve months), your approval may lapse and you will need to reapply.
Do I pay interest on the full loan amount during construction?
No, during construction you only pay interest on the amount drawn down at each stage, not the full approved loan amount. Most lenders offer interest-only repayment options during this phase, with principal and interest repayments starting once the build is complete.
