Dreaming of turning your creativity into a thriving interior design business in Australia? You’re in great company. Interior designers help clients transform homes, offices and retail spaces - and demand for smart, functional design isn’t going anywhere.
But building a successful design studio takes more than a great eye. The right legal setup, clear contracts and ongoing compliance will protect your business, earn client trust and make growth far smoother. If you get the foundations right early, you’ll avoid costly detours later.
In this guide, we’ll walk through the essential legal checklist for starting an interior design business in Australia - from structure and registrations to compliance, contracts and protecting your brand - so you can focus on designing spaces (and a business) you’re proud of.
What Does An Interior Design Business Do?
An interior design business offers professional design services for residential, commercial or hospitality spaces. Depending on your niche, you might provide design consultations, concept development, mood boards, floor plans, FF&E schedules (furniture, fixtures and equipment), 3D renders, styling, property staging, procurement and project coordination with trades.
Some designers operate as solo consultants; others build teams or establish a studio with staff and regular contractors. Even though it’s a creative profession, you’re still delivering a professional service - which means client expectations, consumer rights and your legal responsibilities all come into play.
Plan Your Interior Design Startup (And Set Yourself Up Legally)
Good planning makes your creative vision commercially viable. It also highlights the legal and operational steps you’ll need to tick off before launch.
- Define your niche and services: Residential, retail, hospitality, workplace, healthcare or a mix? Will you offer design-only, procurement and installation, or full project management?
- Map your client journey: From discovery call to concept presentation, revisions, procurement and installation - outline each step and where approvals and payments fall. This will inform your contract and invoicing terms.
- Suppliers and trades: Identify preferred suppliers and licensed contractors. Clarify who contracts with whom, who holds warranties and who carries risk at each stage.
- Insurance and risk: Consider public liability, professional indemnity and business property cover. Contracts should work hand-in-hand with your insurance to manage risk.
- Home-based operations: If you’re starting from a spare room or studio in your house, check local rules about running a business from a residential property.
Documenting these details becomes the basis of your service scope, pricing, proposals and legal documents - and helps you launch with confidence.
Step-By-Step: How To Set Up Your Interior Design Business
1) Choose Your Business Structure
How you structure your business affects liability, tax and growth options.
- Sole trader: Simple and low-cost to start. However, you’re personally liable for business debts and claims.
- Partnership: Straightforward if starting with another person, but partners are generally jointly responsible for debts and obligations.
- Company (Pty Ltd): A separate legal entity that can limit your personal liability and boost credibility. It has more setup steps and ongoing compliance, but many design studios opt for a Company Set Up as they scale.
There’s no one-size-fits-all answer. Consider your risk tolerance, growth plans and whether you’ll bring in co-founders or investors.
2) Register Your Business
- ABN: You’ll need an Australian Business Number to invoice and manage taxes.
- Business name: If you’ll trade under a name that isn’t your personal name, register it with ASIC (for example, using Sprintlaw’s Business Name service).
- Company details: If you incorporate, you’ll receive an ACN and typically adopt a company constitution when you register.
- GST: Register if your turnover will be $75,000 or more in a 12‑month period. Keep clean records for BAS and income tax. (For tax specifics, it’s best to chat with an accountant.)
3) Check Local Rules, Licences And Permits
In most cases there’s no specific licence required to call yourself an interior designer in Australia. But there are still rules to follow:
- Home studio: Confirm council requirements if clients visit your premises or you store stock at home.
- Building and construction work: Any regulated trade work (electrical, plumbing, structural work, waterproofing) must be performed by appropriately licensed contractors. You shouldn’t carry out regulated work yourself unless licensed.
- On-site safety: Ensure contractors follow WHS requirements and site safety plans. Clarify responsibilities in your contracts and scopes of work.
4) Protect Your Brand And Designs
Choose a distinctive business name and check it’s available. To protect your brand identity (name, logo and other brand elements), consider filing a trade mark through Register Your Trade Mark. You should also ensure your client contract addresses who owns designs, drawings and renders at each stage (concepts vs final deliverables).
5) Put Your Core Contracts And Policies In Place
Before you start taking on work, get your legal documents drafted to match your process. At minimum, have clear client terms, a website policy stack and the right agreements for staff or contractors. We cover these in detail below.
6) Set Up Operations And Record-Keeping
Establish a simple workflow for proposals, approvals, variations and progress claims. Keep a clean paper trail for scope changes, selections, deliveries and site issues - it’s invaluable if a dispute arises. Set up invoicing and deposit processes that align with your contract terms.
What Laws Do Interior Designers Need To Follow In Australia?
Every interior design business must comply with general business laws - and some industry-adjacent rules when projects involve building work or on-site coordination. Here are the key areas to consider.
Australian Consumer Law (ACL)
The Australian Consumer Law applies to how you market your services, what you promise and how you handle problems. Avoid misleading or deceptive conduct and ensure claims about products and outcomes are accurate. Be careful with “non-refundable” deposits and cancellation fees - terms must be fair and clearly disclosed. For context on representations and claims, see Sprintlaw’s guides to section 18 (misleading or deceptive conduct) and section 29 (false or misleading representations).
Contracts And Variations
Scope creep is common in design work. Your client contract should spell out inclusions, exclusions, revision limits and how variations are priced and approved. Put variation approvals in writing before you proceed. Clear terms reduce disputes over extra time or costs.
Employment Law (If You Bring In Help)
If you hire staff - even casually - you’ll have obligations under workplace laws and awards. Use written Employment Contracts, pay correct rates and keep appropriate records. If you prefer flexible capacity, consider using a Contractors Agreement with genuine contractors who run their own business. Getting this distinction right matters for tax, super and entitlements.
Privacy And Marketing
If you collect personal information (enquiries, subscriber lists, lead forms), be mindful of privacy obligations. Many small businesses with annual turnover under $3 million are not automatically covered by the Privacy Act 1988 (Cth), but there are important exceptions (for example, if you trade in personal information, provide health services or opt in). Even if not legally required, it’s best practice to publish a clear Privacy Policy, use secure systems and only collect what you need. If you use email newsletters or promos, comply with spam rules and consider the guidance in Sprintlaw’s article on email marketing laws.
Intellectual Property
Protect your brand with trade marks and manage copyright in your designs and photographs. Your contract should state who owns concepts, drawings, renders and final documentation, when rights transfer (if at all), and what the client can do with the deliverables. If you want to share project images in your portfolio or on social media, secure a licence in your contract.
Work Health And Safety (WHS)
Site visits, installations and styling days can involve hazards (manual handling, ladders, power tools, packaging waste). Assess risks, work with licensed trades and ensure everyone on site understands their responsibilities. Keep incident reports and implement sensible procedures for your team.
Tax And Invoicing
Register for GST if your turnover meets the threshold, issue valid tax invoices and reconcile BAS on time. Deposits, progress claims and reimbursements should align with your contract and be transparent to clients. For tax strategy, speak with your accountant.
What Legal Documents Should You Have In Place?
The right documents make your operations professional and help you manage risk. Tailor them to your services and workflow.
- Client Service Agreement or Terms and Conditions: Your core agreement that sets the scope, deliverables, fee structure (fixed, hourly, staged), deposit rules, variations, approvals, lead times, procurement/installation responsibilities, warranties, delays and dispute resolution. A well-drafted Service Agreement keeps everyone aligned.
- Supply And Procurement Terms: If you purchase furniture or finishes for clients, specify who you buy from, who the contract is with, how warranties/returns are managed and when risk passes. A simple Supply Agreement helps with key suppliers.
- Website Terms & Conditions: Set rules for site use, portfolio content and any resources you publish. This pairs well with a Website Terms and Conditions page.
- Privacy Policy: Explains what data you collect, why, and how you store and share it. A Privacy Policy is best practice for most client-facing websites and may be contractually required by certain platforms or partners, even when not strictly mandated by law.
- Employment Contracts / Contractor Agreements: Set expectations for staff or freelancers, including IP ownership, confidentiality, rates, hours and termination. For employees, use an Employment Contract; for external resources, use a Contractors Agreement.
- Non-Disclosure Agreement (NDA): Protects confidential information when speaking with builders, collaborators or prospective commercial clients. A simple Non-Disclosure Agreement is quick to deploy.
- Shareholders or Partnership Agreement (if co‑founders): Covers ownership, decision‑making, vesting, exits and dispute resolution. Put one in place early - before you take on major projects - via a tailored Shareholders Agreement or a Partnership Agreement.
- Trade Mark Filings: For brand protection of your studio name and logo, consider early trade mark applications through Register Your Trade Mark.
You might not need every document on day one, but you should have your client contract, website policies and employment/contractor agreements ready before you start taking on paid work. As you grow, formalise supplier and co-founder arrangements.
Buying A Studio Or Joining A Franchise? Extra Legal Steps
Some designers prefer to buy an existing studio or join a franchise rather than starting from scratch. Both pathways can fast-track brand recognition, but they come with added paperwork - so approach carefully.
- Buying an existing business: Conduct legal due diligence on client contracts, supplier terms, staff arrangements, lease/licences, IP ownership and any disputes. A structured Legal Due Diligence Package helps you uncover risks and negotiate price or terms accordingly.
- Franchising: If a design brand offers franchises, review the disclosure document and agreement, ongoing fees, territory rules and marketing obligations. It’s wise to get a Franchise Agreement Review before you sign.
In both cases, check how client warranties and deposits are handled during transition, and ensure a clear plan for handover and rebranding (if any).
