Building finance regulations exist to protect you, your lender, and the broader housing market from incomplete or substandard projects.
When you apply for construction funding, you're not just proving you can afford the repayments. You're demonstrating that your project meets planning controls, that your builder holds the right licenses, and that your contract protects both parties if something goes wrong. These requirements shape everything from how quickly you can access funds to whether your application gets approved at all.
Why Lenders Require Council Approval Before Settlement
Lenders will not release construction funds until you provide evidence of council approval for your build. This usually means a Construction Certificate or a combined Development Application and Construction Certificate, depending on your council's process. In the Hills District, The Hills Shire Council manages this approval process, and timeframes can vary depending on the complexity of your design and whether your land sits within a heritage conservation area or bushfire-prone zone.
Without council approval, your project lacks legal permission to proceed. A lender funding an unapproved build would carry significant risk, as construction could be halted or the project deemed non-compliant partway through. You'll need to submit council plans that meet the Building Code of Australia, local planning controls, and any relevant environmental or bushfire requirements.
In our experience working with clients building across Castle Hill, Baulkham Hills, and Kellyville, council approval timelines often surprise first-time builders. Approvals for straightforward builds on standard blocks can take six to eight weeks, while more complex sites involving tree preservation, slope management, or bushfire attack level assessments can extend to three or four months. Factor this into your planning, particularly if you're selling an existing property to fund the build.
The Role of a Registered Builder in Your Loan Application
Your lender will require that construction is completed by a registered builder who holds the appropriate licenses in New South Wales. This is non-negotiable for most mainstream lenders. Owner builder finance does exist, but it's offered by a smaller range of lenders, typically at higher interest rates and with stricter eligibility criteria.
A registered builder must provide a fixed price building contract before your construction loan application can proceed. This contract sets out the total build cost, the inclusions and exclusions, the construction timeline, and the progress payment schedule. Lenders use this document to determine the loan amount and structure the progressive drawdown around the agreed payment stages.
The contract must also confirm that the builder holds valid home warranty insurance, which protects you if the builder becomes insolvent or fails to rectify defects. In New South Wales, this insurance is mandatory for residential building work valued over a certain threshold. Your lender will verify this coverage as part of the assessment process.
How Fixed Price Contracts and Cost Plus Contracts Affect Approval
Most lenders prefer fixed price building contracts because they provide certainty around the total project cost. Under a fixed price contract, the builder agrees to complete the project for a set amount, regardless of cost overruns. This makes it easier for lenders to assess risk and structure the loan.
Cost plus contracts, where the builder charges for actual costs incurred plus a margin, introduce variability that lenders view as higher risk. Some lenders will not approve construction funding under a cost plus arrangement. Those that do may require a larger deposit, cap the loan-to-value ratio, or build in a contingency buffer to account for potential cost escalation.
Consider a scenario where a builder quotes under a cost plus contract for a custom design home in Kenthurst. The builder estimates the project at a certain range, but the final cost depends on material prices, subcontractor availability, and unforeseen site conditions. A lender may approve the loan but base the advance amount on the lower end of the estimate, leaving the buyer to cover any excess from their own funds. If you're committed to a cost plus approach for design flexibility, discuss this upfront with your broker to identify which lenders will support the structure.
Construction Draw Schedule and Progressive Payment Requirements
Construction loans release funds in stages, tied to completion milestones rather than as a lump sum. This is called a progressive drawdown, and it aligns with the progress payment schedule outlined in your building contract. Typical stages include base stage, frame stage, lockup stage, fixing stage, and practical completion.
Before each progress payment is released, the lender will arrange a progress inspection to verify that the work has been completed to the required standard. The inspection is usually carried out by a quantity surveyor or building inspector. If the work doesn't meet expectations or falls behind the agreed schedule, the lender may withhold the drawdown until the issue is resolved.
Lenders only charge interest on the amount drawn down at each stage, not the full loan amount. During construction, most loans operate on an interest-only repayment basis, meaning you pay only the interest accrued on the funds released so far. Once construction reaches practical completion and you receive the Occupancy Certificate, the loan converts to a standard principal and interest home loan, known as a construction to permanent loan.
Be aware that most lenders charge a Progressive Drawing Fee each time funds are released. This fee covers the cost of the inspection and administration. It's usually a few hundred dollars per drawdown, and it's either deducted from the amount released or charged separately to your transaction account.
Timeframes and the Requirement to Commence Building
Most construction loan approvals require you to commence building within a set period from the Disclosure Date, which is the date your formal loan offer is issued. This period is typically six months, though some lenders allow up to twelve months depending on the circumstances.
If you haven't started construction within this window, your approval may lapse, and you'll need to reapply. Interest rates, lending policies, and your financial circumstances may have changed in the interim, which could affect your borrowing capacity or the terms offered.
For clients purchasing land and construction packages in growth areas like Box Hill or Kellyville, this timeframe can feel tight. By the time you settle on the land, finalise your design, obtain council approval, and sign off on the building contract, several months may have passed. Work backwards from your expected construction start date to ensure you allow enough time for each stage.
Additional Compliance Requirements for Renovation and Knock-Down Rebuild Projects
Renovation finance and knock-down rebuild projects carry additional regulatory considerations. If you're demolishing an existing dwelling, you'll need a demolition permit from council before any work begins. The lender will usually require evidence of this permit before releasing the first drawdown.
For renovation projects, the scope and scale of the work determine whether you need a Development Application, a Complying Development Certificate, or just a Construction Certificate. Minor cosmetic updates may not require council approval at all, but structural changes, extensions, or alterations to heritage-listed properties almost always do.
Lenders will also assess whether the proposed renovation adds sufficient value to the property to justify the loan amount. If you're borrowing to renovate but the after-renovation valuation doesn't support the total debt, the application may be declined or the loan amount reduced. Renovation Finance can be structured similarly to construction loans, with progressive drawdowns tied to completion stages, or as a lump sum if the project is small enough to be funded upfront.
How Land and Construction Packages Are Assessed
When you're purchasing a land and construction package, lenders assess both components together. You'll need a contract of sale for the land and a fixed price building contract for the construction, both signed and unconditional before the loan can settle.
The lender will order a valuation based on the completed property, not just the land value. This is called an 'as if complete' valuation. The valuer considers the land price, the build cost, and comparable sales of completed homes in the area to determine what the property will be worth once construction finishes.
If the valuation comes in lower than the combined cost of land and construction, you may face a shortfall. Some buyers assume that because they've negotiated a fixed price with the builder, the lender will automatically approve the full amount. That's not always the case. The loan amount is based on the lower of the contract price or the valuation, so a conservative valuation can reduce your borrowing capacity.
What Happens If Your Builder or Project Encounters Issues Mid-Construction
If your builder becomes insolvent or abandons the project, your home warranty insurance is the first line of protection. This insurance covers the cost of completing the work or rectifying defects, subject to certain limits and conditions. Your lender will be notified if a claim is made, and they may place a hold on further drawdowns until the situation is resolved.
In some cases, lenders will allow you to engage a new builder to complete the work, provided the new builder can demonstrate that they're taking over a partially completed project under a compliant contract. This process can be complicated, and it often requires a fresh valuation, updated council approvals, and a revised progress payment schedule.
If construction stalls and you're unable to complete the build, the lender may require you to sell the property or convert the loan to a land-only loan, which usually comes with a higher interest rate and stricter servicing criteria.
Understanding Your Obligations Around Progress Payments to Subcontractors
Your building contract may specify that progress payments are used to pay subcontractors such as plumbers, electricians, concreters, and carpenters. While the builder is responsible for managing these payments, delays or disputes can affect the construction timeline and your loan.
Some lenders offer the option to pay subcontractors directly under certain contract structures, though this is more common in owner builder finance arrangements. For standard builds with a registered builder, the lender releases funds to the builder, who then distributes payments according to the contract.
If you're considering an owner builder project, understand that lenders treat these applications differently. You'll need to demonstrate relevant building experience, provide detailed project plans, and usually accept a lower loan-to-value ratio. The lender may also require more frequent inspections and tighter oversight of the progress payment schedule.
Whether you're building a custom design home, working within a house and land package, or funding a renovation, the regulatory framework around construction loans exists to ensure your project is viable, compliant, and protected. Understanding these requirements before you apply helps you prepare the right documentation, avoid delays, and move forward with confidence.

Frequently Asked Questions
Do I need council approval before my construction loan settles?
Yes, lenders require evidence of council approval, usually a Construction Certificate or combined Development and Construction Certificate, before releasing construction funds. Without this, your project lacks legal permission to proceed and the lender will not fund the build.
What is the difference between a fixed price contract and a cost plus contract for construction loans?
A fixed price contract sets a total build cost regardless of overruns, which most lenders prefer. A cost plus contract charges actual costs plus a margin, introducing variability that some lenders won't approve or will only support with stricter conditions and lower loan-to-value ratios.
How do progressive drawdowns work during construction?
Funds are released in stages tied to completion milestones such as base, frame, lockup, and fixing stages. Before each drawdown, a progress inspection verifies the work meets standards, and you only pay interest on the amount drawn down so far.
Can I use owner builder finance instead of hiring a registered builder?
Owner builder finance is available but offered by fewer lenders, usually with higher interest rates and stricter eligibility criteria. You'll need to demonstrate building experience, provide detailed project plans, and accept a lower loan-to-value ratio.
What happens if my builder becomes insolvent during construction?
Your home warranty insurance covers completion costs or defect rectification, subject to limits. The lender may hold further drawdowns until resolved, and you may need to engage a new builder with updated approvals and a revised payment schedule.
