Before any building starts, most buyers ask the same question: how much cash do I actually need? The answer is not a single figure, because two separate deposits sit inside most new builds. One is set by NSW law and the other by your lender. Understanding new home building deposit NSW rules early protects your savings and keeps your project moving. This guide explains both deposits, shows worked examples and lists what to check before you pay anyone.
What Is the Maximum Builder Deposit Allowed in NSW?
So, how much deposit does a builder require in NSW? Never more than the legal cap, and often less. Under the Home Building Act 1989, the maximum builder deposit NSW law allows is 10 percent of the contract price for work valued over $20,000. For jobs of $20,000 or less, the cap is 20 percent.
A building contract deposit is the first payment you make when you sign. It secures your place in the builder’s schedule and covers early costs such as ordering materials and administration. The cap applies even if the paperwork says otherwise, so a clause asking for more is not enforceable. If a builder requests a larger amount, pause and contact NSW Fair Trading before signing anything.
For example, on a $600,000 build, the most a builder can ask for as a deposit is $60,000. Many reputable builders ask for less, so compare offers before you commit.
What Is the Difference Between a Builder Deposit and a Home Loan Deposit?
The two terms are often mixed up. Understanding the difference between builder deposit and home loan deposit Australia buyers deal with is important, because each is paid for a different reason and to a different party.
The builder deposit goes to the builder when you sign the build agreement. It is capped by law and counts towards your total build cost.
The home loan deposit is your own contribution to the overall project. The lender uses it to decide how much it will lend, and it is not paid to the builder as one lump sum. Lenders measure your deposit percentage against the combined value of land and build. A construction loan deposit is the equity or cash a lender requires before approving your loan, commonly between 5 and 20 percent of the project value.
If you already own your land, its equity may count towards that requirement. In that case, your cash may not need to cover the whole amount.
Can You Build a House in NSW With a 5% Deposit?
Yes, it is possible, but with conditions. Some lenders accept deposits as low as 5 percent for eligible borrowers. The minimum deposit to build a house in NSW is set by each lender rather than the builder, so requirements vary between banks and loan types.
When your deposit is below 20 percent, you will usually pay Lenders Mortgage Insurance (LMI). LMI protects the lender, not you, and the premium can often be added to the loan. It is worth asking your broker for a quote early, because the cost can be significant on larger loans.
Eligible first home buyers may avoid LMI through the Home Guarantee Scheme, where the federal government guarantees part of the loan so you can proceed with a 5 percent deposit. Price caps, eligibility rules and available places can change, so check current details with Housing Australia or your broker.
A first home buyer deposit of 5 percent also does not cover everything. Your deposit savings still need to stretch to fees, insurance and site costs, which the next sections explain.
How Much Deposit Do You Need for Different Building Budgets?
The maximum deposit for a new home build in NSW rises with your budget. At the 10 percent cap, builder deposits look like this:
Build of $500,000: up to $50,000
Build of $700,000: up to $70,000
Build of $900,000: up to $90,000
Lender requirements are calculated differently. On a total project of $900,000 including land:
5 percent deposit: $45,000
10 percent deposit: $90,000
20 percent deposit: $180,000
These figures are examples only. A higher deposit usually means a smaller loan, lower repayments and no LMI. A lower deposit gets you building sooner but costs more over time. Your broker can model each scenario against your income and the lender’s policy, so you can see the real trade-off before deciding.
What Is Included in Your Upfront Building Costs?
Your deposit is only one part of the cash you need early on. Typical items include:
The builder deposit
Insurance certificate costs, often included in your quote
Plans, engineering and soil testing
Council or private certifier fees
Survey and legal fees
Loan establishment fees
Stamp duty on the land, where it applies
Site preparation costs deserve special attention. Clearing, levelling, retaining walls, drainage and service connections can add thousands of dollars, particularly on sloping or bushland blocks. Some builders exclude these items from their base quote, so ask for a written allowance before you commit. A clear list of inclusions and exclusions helps you avoid surprises once the machinery arrives.
Do You Need Home Building Compensation Cover Before Paying?
Yes. In NSW, a builder must arrange this insurance before starting Residential building work valued over $20,000, and before accepting any payment, including your deposit. The cover protects you if the builder dies, disappears, becomes insolvent or fails to comply with a tribunal order.
Always ask for the certificate of insurance and check that the details match your contract, including the address and the work described. If a builder asks for money without providing it, do not pay. This is one of the simplest and most effective ways to protect your deposit.
How Do Construction Loan Progress Payments Work?
Construction finance works differently from a standard home loan. Instead of releasing the full amount on day one, the lender pays the builder in stages as work is completed. Typical stages are:
Base or slab
Frame
Lock-up
Fixing
Practical completion
A valuer or inspector often confirms each stage before funds are released. The builder submits a claim, you approve it and the lender pays. You only pay interest on the amount drawn, so repayments start small and grow as the build advances.
Your builder payment schedule should match your lender’s stages exactly. A mismatch can delay payments and slow the build, so share both documents with your broker before signing.
Does a House and Land Package Require Two Deposits?
Often, yes. A land purchase deposit, commonly 10 percent of the land price, is paid when contracts for the land are exchanged. A second deposit is then paid under the build agreement, within the legal cap. Some packages combine both parts into one arrangement, so confirm exactly what you are signing and how many payments are due.
Land settles first, and construction starts afterwards. Plan your cash flow so the land deposit, the builder deposit and your loan costs do not collide. Ask your solicitor to review both documents together, so you understand every obligation before you sign.
What Should You Check Before Paying Your Builder?
Use this checklist before you transfer any money:
- Confirm the builder’s licence on the NSW Fair Trading website
- Check the deposit is within the 10 percent cap
- Receive the insurance certificate before paying
- Insist on a fixed-price building contract with inclusions and exclusions listed clearly
- Make sure payment stages match your loan
- Ask for written receipts for every payment
- Have a solicitor review your home building contract
Taking an hour to check these items can prevent costly disputes later.
Build With Confidence
A new home involves two deposits: the builder deposit, capped at 10 percent for most jobs in NSW, and the lender’s requirement, which depends on your finances and loan. Plan for both, add the extra costs on top and verify every document before you pay.
At Home Choice Australia, we guide clients through each stage of the build, from early budgeting to handover. Contact our team to discuss your plans and get a clear picture of what you need to start.
Frequently Asked Questions
Can a builder ask for more than 10 percent upfront?
For work over $20,000, no. The law caps the deposit at 10 percent, and any clause asking for more is not enforceable.
Does the deposit reduce my final bill?
Yes. The amount you pay at signing counts towards the total build cost, so it is deducted from what you owe later.
Can I use the equity in my land instead of cash?
Many lenders accept land equity as part of your contribution. Policies differ, so confirm with your broker before assuming it will cover your requirement.
Do I pay stamp duty on the building work?
Stamp duty generally applies to the land, not the construction cost. Exemptions or concessions may apply, so check with Revenue NSW or your solicitor.
Can I get my deposit back if I change my mind?
It depends on your agreement and any cooling-off rights that apply. Read the terms carefully and get legal advice before signing.
Should I speak to a broker before signing with a builder?
Yes. A broker can confirm how much you can borrow, estimate costs such as LMI and make sure your loan stages suit the build.
