If you've been researching home lifts in Australia, you've probably come across AS1735. It gets referenced in product brochures, on supplier websites, and sometimes in conversations with installers - but what does it actually mean for you as a buyer?
The short answer is this: AS1735 is a voluntary technical framework, not a consumer protection law. Understanding what it is, and what it isn't, will help you ask better questions, and make a more confident decision when choosing a residential lift.
What Is AS1735?
AS1735 is a series of technical standards developed by Standards Australia covering the design, manufacture, installation, and maintenance of lifts, escalators, and moving walks. First introduced in 2003 and updated in 2016, it is the primary reference framework used by lift designers and engineers across Australia.
Importantly, AS1735 is a voluntary standard - it does not have legal force on its own. Australian standards are designed to help industry meet high expectations of safety and quality, but they allow for variation as long as an equivalent level of safety is demonstrated. Manufacturers are not legally required to claim compliance with AS1735 to sell a home lift in Australia.
Where AS1735 does carry legal weight is through its relationship with the National Construction Code (NCC). The NCC references AS1735 as a deemed-to-satisfy standard - meaning that compliance with the relevant parts of AS1735 is one recognised way to meet the NCC's legal requirements for lift safety. It is not the only way: lift designs that go beyond the standard through innovation can satisfy the NCC via documented engineering principles, provided those differences represent an improvement in safety, not a reduction.
In practice, what this means for a home lift buyer is that the standard is a useful reference point - but the quality and accountability of the company behind the lift matters most.
What Actually Matters More Than the Standard Itself
Design engineers who work for reputable organisations lead the standard - not the other way around. Australian standards are, by their nature, slow to be published and slow to be updated. The best home lift products on the market are often ahead of what the standard specifies, because innovation moves faster than the standards process.
This means that a residential lift from a highly reputable, well-engineered company might have elements that differ from AS1735 - not because it is unsafe, but because it is more advanced. Conversely, a lift that claims full compliance with the standard is not automatically the better or safer product.
What a buyer should focus on is the pedigree of the organisation: their engineering rigour, their documentation, their history in the market, and their commitment to after-sales support. These are better indicators of long-term quality than a compliance claim alone.
Design Registration: One Of The Most Meaningful Quality Signals
One of the most meaningful quality signals available to Australian home lift buyers is whether the lift's design has been independently validated and registered with a statutory authority - a process known as design registration.
It is important to understand what design registration is, and what it is not. Design registration means the lift's design - not the individual unit installed in your home - has been assessed and lodged with a statutory authority. The process works in stages: a qualified engineer verifies the design; an independent third-party engineer then validates it; and the design is registered with a state or territory statutory authority, such as WorkSafe NSW. Registration by one state authority is recognised nationally through a cooperative arrangement between states.
This is a different process from the registration of an individual item of plant, which is a separate requirement that applies to commercial lift installations. For residential home lifts, it is the design registration that is the relevant quality signal - not individual unit registration.
Design registration documentation will specify which sections of AS1735 the lift's design complies with, and where the design differs from the standard - for example, where an innovative design choice goes beyond the standard's requirements. Both compliance with AS1735 and documented engineering principles are accepted pathways under the NCC.
Residential vs. Commercial Lifts: An Important Distinction
For commercial lifts, the individual installed unit must be registered as a plant item and placed on a legally enforced maintenance schedule. For residential home lifts installed on private property, state statutory authorities have no jurisdiction to require or enforce individual unit registration or ongoing maintenance. This makes your choice of supplier - and their long-term service commitment - all the more important.
Which Parts Of AS1735 Apply To Residential Lifts?
AS1735 is a series of parts, not a single document - and not all parts apply to every home lift. For the residential lifts most commonly installed in Australian homes, the two most relevant parts are Part 12 and Part 15.
AS1735.1 - General Requirements
AS1735.1 sets broad baseline requirements that apply across all lift types as a starting point. It is deliberately wide in scope. Where a more specific part of the standard exists - such as Part 15 for low-rise lifts - that part's requirements take precedence over AS1735.1 where the two differ, while AS1735.1 continues to apply as a baseline for everything the specific part does not address.
AS1735.12 - Lifts for People with Disabilities
This part covers accessibility requirements including lift dimensions, control button placement, and features designed to ensure lifts are usable by people with limited mobility. It is particularly relevant for residential lifts intended to support ageing-in-place or mobility access.
AS1735.15 - Low-Rise Passenger Lifts (Non-Automatic Controlled)
This is the part most applicable to through-floor and shaftless home lifts. It covers low-speed passenger lifts operated by a constant pressure (hold-to-run) control, intended primarily for people with limited mobility. See the section below for more detail.
A Note On Low-Rise & Through-Floor Home Lifts
Through-floor and shaftless home lifts fall under AS1735.15 - the low-rise passenger lift standard. It is worth noting that the standard does not use the term "through-floor lift" explicitly; these lifts fall under Part 15 because they meet its defining criteria: low-speed travel, constant pressure operation, and a maximum travel distance of 4 metres (which determines the typical two-floor limitation on this lift type).
Part 15 is complementary to AS1735.1 and is intentionally more flexible in certain areas, reflecting the lower-risk, lower-speed context of this lift type. To offset that flexibility, it requires the lift to be operated by a responsible operator - which is why through-floor home lifts feature hold-to-run controls, an isolation key, and lower operating speeds. These are requirements of the standard, not arbitrary product limitations.
Comparing lift types? Where Part 15 specifies differently from AS1735.1, Part 15 takes precedence - it does not mean AS1735.1 is irrelevant to these lifts, only that Part 15 is the more specific governing standard in those areas. If you're comparing a through-floor home lift against a traditional cabin lift and find they differ on certain specifications, this is often because different parts of the standard apply to each - not because one is less compliant than the other.
Three Questions Worth Asking Any Home Lift Supplier
Because AS1735 is a voluntary framework and compliance is not standardised across all products on the market, the right questions will tell you more than any checklist. Ask these of any residential lift supplier you're seriously considering:
- Is your home lift design registered with a statutory authority - and can you show me the registration documentation?
- Which parts of AS1735 does your design comply with, and are there areas where your design differs from the standard? If so, how is that documented?
- What does ongoing service and maintenance support look like over the life of the lift?
A supplier who can answer all three clearly, and back them up with documentation, is demonstrating the engineering rigour and transparency that matters far more than a compliance claim on a brochure.

The Bottom Line...
AS1735 gives the lift industry a common reference point for safety and quality - and that is genuinely useful. But it is a voluntary framework, it moves slower than innovation, and a compliance claim alone is one input among many when assessing a home lift product and supplier.
A residential lift is a long-term investment - typically with a useful life of 25 years or more. The standard a supplier references matters less than the engineering behind their product, the independence of their validation process, and their commitment to supporting you long after installation.
Frequently Asked Questions
Is AS1735 mandatory for home lifts in Australia?
No. AS1735 is a voluntary standard - it does not have the force of law on its own. However, it is referenced within the National Construction Code (NCC) as a deemed-to-satisfy standard, meaning compliance with relevant parts of AS1735 is one recognised way to meet the NCC's legal requirements for lift safety. Suppliers can also satisfy the NCC through documented engineering principles where their design goes beyond what the standard specifies.
What does design registration mean for a home lift?
Design registration means a lift's design - not the individual unit - has been independently verified by a qualified engineer, validated by a third-party engineer, and registered with a state or territory statutory authority, such as WorkSafe NSW. It is a meaningful quality signal because it involves independent assessment, not just a manufacturer's own compliance claim. Registration by one state authority is recognised nationally. For residential lifts, it is the design registration that is relevant - individual unit registration is a separate requirement that applies to commercial lift installations.
What is AS1735 Part 15?
AS1735.15 is the part of the standard that applies to low-rise passenger lifts operated by constant pressure (hold-to-run) controls - the category that includes most through-floor and shaftless home lifts. It sets a maximum travel distance of 4 metres and is the more specific governing standard for this lift type, taking precedence over the general AS1735.1 requirements where the two differ.
How do I know if a home lift meets Australian standards?
Ask the supplier for their design registration documentation. This will specify which parts of AS1735 the lift's design complies with, and how any differences from the standard are managed. A reputable supplier should provide this readily. Beyond documentation, look for a company with a strong service history, genuine after-sales support, and transparent answers to questions about their engineering and compliance process.
