Residential vs Commercial Lifts

What separates a residential lift from a commercial one

Both move people between floors on guide rails, and both can look similar from the inside. The difference is what they are built and certified to withstand. A residential lift is a private-residence lift under AS/NZS 1735.18 — light duty, low speed, modest capacity, one household. A commercial lift is built for public duty: continuous calls, heavier cars, faster travel, and the wear that comes from strangers using it all day.

Duty cycle is the honest way to describe it. A home lift might make a dozen trips on a busy day. A lift in a small office or an apartment building can make several hundred. The components — motor, ropes or belts, door gear, controller — are sized for that difference from the outset, which is why you cannot simply move one lift into the other setting.

Standards: the reason you can't swap one for the other

This is the row that matters most. Residential and commercial lifts are certified against different Australian Standards, and those standards define where each may be used.

A private-residence lift is built to AS/NZS 1735.18:2002, which covers automatically controlled, low-speed passenger lifts inside a private home. It is not a public-building standard. A commercial passenger lift is built to AS 1735.2, with AS 1735.12 governing accessibility, sits under the National Construction Code, and must meet the disability access provisions that apply to public premises. Our guide to lift standards in Australia sets out the full AS 1735 series and where each part applies, and NCC lift requirements covers when a commercial building must provide an accessible lift at all.

The practical consequence is firm: a lift certified for a private residence generally cannot lawfully be used in an office, shop, medical suite or the common area of an apartment block. It has not been assessed for public duty or accessibility, and a building certifier will not sign it off.

Capacity, speed and duty cycle

A residential lift typically carries 200–400 kg — enough for two or three people, or a wheelchair user and a carer — and travels at around 0.15–0.3 m/s. That is deliberate. Slow, quiet and compact suits a home.

A commercial lift starts where the residential range ends. Capacities run from 630 kg to 2,500 kg and beyond, and speeds of 1.0 m/s and higher are normal so the lift can clear waiting traffic. Those numbers reflect a different job: moving many people, prams, trolleys and deliveries, reliably, for decades.

Cost, and why commercial lifts run higher

A residential lift is the more affordable of the two, because it is smaller, slower and lighter in duty. A commercial lift costs more for concrete reasons — heavier engineering, larger machines, fire and accessibility compliance, and the testing and certification a public installation demands.

If you are weighing a lift for a house, the residential category — see home lifts — is almost always the right and cheaper starting point. Specifying a commercial lift for a family home means paying for public-duty capability the household will never use.

Maintenance and lifespan

Both lift types need regular servicing, but the intensity differs. A residential lift usually runs on a light annual service. A commercial lift needs a structured maintenance contract, more frequent visits, and often 24/7 breakdown cover — because downtime affects a whole building of people and, in some settings, compliance.

Lifespan follows duty and upkeep. A well-maintained commercial lift is built to run for 20–25 years before major modernisation, under far heavier use than a home lift ever sees. A residential lift, used lightly, can last comparably with much less intervention. Neither category simply lasts longer in the abstract — the commercial lift is engineered to survive a much harder working life.

Can you put a commercial lift in a home — or a home lift in a business?

You can install a commercial lift in a large private home, and some architectural or multi-generational projects do exactly that for the extra capacity and speed. It is legal and it works. It is just expensive, and usually unnecessary.

The reverse is the real trap. A private-residence lift cannot be dropped into a shop, office or apartment common area, because it is not certified for public duty or accessibility. A genuinely private lift inside a single-tenancy small business is a grey area — confirm the classification with your state regulator and a certifier before you rely on it, because the rule turns on public access, not on the building's label.

For most buyers the decision is straightforward: a home takes a residential lift, a public or shared building takes a commercial one, and the standards make the call for you. If your project sits on the line — a home business, a mixed-use conversion, a large multi-generational house — get the duty class confirmed early.
