10 Things to Ask Your Builder Before Signing a Contract in NSW
10 Things to Ask Your Builder Before Signing a Contract in NSW
Signing a building contract is one of the biggest financial decisions you’ll ever make. Yet most homeowners in Western Sydney rush through it — excited about their new home but unaware of what to look for. Before you put pen to paper, here is your essential builder contract NSW checklist to protect yourself and your investment.
questions to ask builder before signing contract NSW
1. Are You a Licensed Builder in NSW?
This should be your very first question. In NSW, any residential building work over $5,000 must be carried out by a licensed contractor. Ask for their licence number and verify it on the NSW Fair Trading licence check.
Here is licensed builder NSW what to check — start with their licence number on NSW Fair Trading
Crystal Homes holds Licence No. 372079C — fully licensed and insured for all residential construction across Western Sydney.
2. What Is Included in the Contract Price?
Many homeowners are surprised by costs that were never clearly outlined upfront. Always ask:
- Are site costs included?
- What about council fees, DA or CDC lodgement costs?
- Are BASIX compliance costs covered?
- What finishes and inclusions are standard?
A genuine builder will give you a fixed-price contract with a detailed inclusions list — no nasty surprises at handover. Check our New Home Inclusions Guide to understand what you should expect.
3. What Type of Home Building Contract Will Be Used?
In NSW, most residential builders use a HIA (Housing Industry Association) or MBA (Master Builders Association) standard contract. These are regulated and protect both parties. Be cautious of builders using custom contracts that lack consumer protections. Always read every clause — especially variations, delays, and dispute resolution sections.

4. How Do You Handle Variations?
Variations are changes made to the original design or specifications after the contract is signed. They can blow out your budget significantly if not managed properly. Ask:
- How are variations documented?
- Who approves them?
- What is the variation markup percentage?
A solid home building contract NSW guide will outline variation processes clearly. Ensure everything is in writing before any work proceeds.
5. What Is the Build Timeline and Payment Schedule?
Understanding the timeline protects you from delays. Ask for a clear project schedule with milestones. The payment schedule should align with progress payments at defined construction stages — not arbitrary requests for upfront lump sums.
For most builds in Western Sydney, expect a timeline of 12–18 months from approval to handover. See our full Home Build Timeline Guide for a stage-by-stage breakdown.
6. What Warranties and Structural Guarantees Are Provided?
NSW law requires builders to provide a statutory warranty on all residential work. At minimum you should receive:
- 2 years on minor defects
- 6 years on major structural defects
Ask your builder what goes beyond the statutory minimum. Crystal Homes offers a 25-Year Structural Guarantee — something worth asking every builder on your shortlist about
7. Do You Handle DA and CDC Approvals?
Navigating council approvals can be stressful. When choosing a builder in Sydney, always confirm whether they manage Development Applications (DA) or Complying Development Certificates (CDC) on your behalf. Ask:
- Who lodges the application?
- What are the additional costs?
- How long does approval typically take in your council area?
8. Can I See Examples of Completed Homes?
Any reputable builder will proudly show you completed projects. Ask to visit a display home or speak with previous clients. This is the most reliable way to assess build quality — something no brochure can replace.
9. What Is Your Insurance Coverage?
Before signing, confirm the builder holds:
- Home Building Compensation (HBC) insurance — mandatory in NSW for work over $20,000
- Public liability insurance
- Workers compensation insurance
This protects you if the builder becomes insolvent, dies, or disappears before completing your home. Cross-check with NSW Fair Trading.
10. What Happens If There Are Disputes?
No one wants disputes — but knowing the process matters. Your builder contract NSW checklist must include clarity on:
- How disputes are raised and documented
- Who handles mediation
- Whether NSW Fair Trading or NCAT is referenced in the contract
A transparent builder will have no issue walking you through their dispute resolution process upfront.
