Lift (Elevator) Size Guide for Homes and Buildings

A lift is the one element of a building that cannot be adjusted on site. Walls can be shifted, windows resized and kitchens redesigned, but a lift shaft that is 100 mm too narrow, a pit that is 300 mm too shallow or an overhead that clashes with the staircase roof will either force a smaller lift than intended or mean breaking structure. In Indian projects this happens more often than it should: a G+4 apartment block is designed with a shaft copied from an old drawing; a bungalow owner decides to add a home lift after the slabs are cast; a small hospital or clinic is planned without a stretcher-sized car. The fixes are expensive and sometimes impossible.

The second problem is that lift sizes are often discussed loosely. People ask for an "8-passenger lift" without realising that the car can be wide and shallow or narrow and deep, that each manufacturer's shaft requirement differs slightly, and that pit depth and overhead height depend on speed, drive type and the standards the lift must meet. Accessibility, fire safety and stretcher requirements add their own minimums.

This guide gives the typical dimensions used in Indian practice for home lifts, passenger lifts, stretcher and bed lifts and goods lifts, explains the parts of a lift shaft, and sets out what the architect, the structural engineer and the lift company must each confirm. The figures are indicative planning ranges drawn from National Building Code of India 2016, Part 8 (Building Services), Section 5 on lifts, from the relevant Indian Standards for lifts, and from typical manufacturer layouts. Lifts are safety-critical equipment: the final dimensions, design and installation must always come from a licensed lift company and comply with the state's lift rules and inspections.

A short history of the lift

Hoists for lifting goods are ancient, but the passenger lift as we know it depends on one invention: the safety brake that stops a car from falling if the hoisting rope breaks. Elisha Otis demonstrated such a device in New York in the 1850s, and within a few decades steam and hydraulic passenger lifts were being installed in commercial buildings. Electric lifts followed in the late nineteenth century, and the combination of electric traction lifts and steel-frame construction made the high-rise building possible. Lifts arrived in Indian cities in the early twentieth century, initially in hotels, offices and grand residential buildings in the major port cities.

Later developments changed lifts more quietly. Automatic controls replaced lift operators; collective control let a single lift gather calls efficiently; variable-frequency drives made rides smoother and cut energy use; and from the 1990s, compact gearless machines allowed the machine-room-less (MRL) lift, with the motor mounted inside the shaft. MRL traction lifts are now the most common choice in Indian residential buildings because they save the rooftop machine room. In parallel, compact home lifts — small traction, hydraulic, screw-driven and pneumatic designs — have made lifts practical in bungalows and duplexes.

Types of lift and where each fits

Lifts are classified by their drive and by their use. For drive type, most Indian buildings use electric traction lifts, either with a machine room above the shaft or machine-room-less. Hydraulic lifts push the car from below with a ram and suit low rises. Home lifts are a separate family of compact designs for private houses. For use, the main categories are passenger, goods, stretcher or bed (hospital), service, and fire lifts, each with different car sizes and requirements.

Capacity, car size and shaft size

Passenger lift capacity in India is stated in persons and kilograms, with each person counted at 68 kg in the Indian standards — so a 6-person lift is rated at 408 kg, an 8-person lift at 544 kg, a 10-person lift at 680 kg, a 13-person lift at 884 kg, and so on. The standards relate the rated load to the maximum usable floor area of the car so that a car cannot be overloaded simply by crowding. Within that limit, the car's proportions can vary: a wide, shallow car is quicker to load and unload, while a narrow, deep car accepts a wheelchair with a companion or a stretcher.

The shaft (or hoistway) must be larger than the car on every side to accommodate guide rails, the counterweight, door mechanisms and running clearances. The counterweight usually sits at the side or the back of the car, which is why shafts are wider or deeper than the car by different amounts. The table gives typical planning sizes; individual manufacturers' layouts differ by up to about 100–200 mm, so the drawing should be confirmed against the chosen lift company's layout before structural design.

Pit, overhead and machine room

A lift needs space below the lowest landing and above the highest landing as well as the shaft itself. The pit is the part of the shaft below the lowest floor level; it houses buffers and gives safety space under the car. The overhead (or headroom) is the clear height from the top landing floor to the underside of the shaft ceiling slab; it accommodates the car height, the equipment on top of the car and safety clearance, and in an MRL lift often the machine itself. Both depend on lift speed and drive type: faster lifts need deeper pits and taller overheads because they need longer stopping distances.

Speed is chosen from the building height and expected traffic. As a general guide, 1.0 m/s suits most low and mid-rise residential buildings of up to about eight to ten floors; 1.5–1.75 m/s is common for taller residential and office buildings; and higher speeds are used in high-rise towers, where a lift traffic analysis by the lift consultant or manufacturer should decide the number, size and speed of lifts. Home lifts run much slower, usually well under 0.5 m/s, which is why their pits and overheads are small.

Home lifts for bungalows and duplexes

A home lift is the fastest-growing part of the Indian lift market, driven by ageing parents, multi-storey bungalows on narrow plots and duplex penthouses. Planning one is much easier at the design stage than as a retrofit. The minimum practical arrangement is a shaft of roughly 1200 × 1200 to 1500 × 1500 mm, a car of about 800–1000 × 900–1200 mm carrying two to four people, a shallow pit and an overhead of about 2500–2900 mm above the top landing — which often means the shaft must rise above the terrace slab with a small headroom structure. To allow a wheelchair user, the car should be at least about 900 mm wide and 1200–1400 mm deep with an 800 mm clear door, and the lift company should confirm the exact size.

Retrofitting a lift into an existing house is possible but always involves compromises. A shaft can be built inside a staircase well, in a corner of a room or as an external tower attached to the house, but each option means cutting slabs and possibly adding foundations, which requires a structural engineer's design and approval. Self-supporting pneumatic or screw-driven home lifts need very small pits and can be installed with less civil work, at the cost of a smaller car and slower ride. In every case, the existing structure must be checked before slabs are cut, and the lift must still meet the state's lift rules where they apply to private residences.

Accessible, stretcher and fire lifts

Three special categories have their own requirements. Accessible lifts serve wheelchair users and people with reduced mobility; NBC 2016 Part 3 and the Government of India's Harmonised Guidelines on accessibility set minimum car and door sizes, control heights, handrails, audible and visual signals and landing space. A clear door of at least 900 mm and a deep car are typical outcomes, and an 8-person or larger car with a deep plan usually meets the requirement — but the current text of the code should be checked for each project. Stretcher and bed lifts are required in hospitals and are increasingly provided in residential towers so that an ambulance stretcher can be carried in a lying position; they need a deep car of roughly 2100 mm or more.

Fire lifts are required by NBC 2016 Part 4 (Fire and Life Safety) in high-rise buildings, for use by firefighters during an emergency. The code sets requirements including minimum capacity, door width, speed, protected lobbies, fire-resisting shaft enclosure and an alternative power supply, and the local fire authority applies them during approval. These are not items to design from a general article: the architect, fire consultant and lift company must work from the code and the fire authority's conditions.

How many lifts, and who decides

Whether a building must have a lift, and how many, is decided by the local development control regulations and bye-laws, which commonly require lifts above a certain height or number of floors, and by the expected traffic. As a planning rule of thumb, residential buildings often provide about one passenger lift for every 25–40 dwellings, and towers usually have at least two so that one remains in service during maintenance; one of them is often a stretcher-sized car. Offices need more capacity at the morning peak and should have a traffic analysis. The architect should check the local rules early, because lift numbers affect the core size, lobby area and floor efficiency of the whole building.

Responsibilities are shared. The architect plans the shaft, lobby and machine space; the structural engineer designs the shaft walls, pit, beams and hoisting points; the electrical consultant provides the dedicated power supply, earthing and lighting; and the licensed lift company provides the layout drawing, supplies and installs the lift, and arranges the statutory inspection. In most states, lifts must be registered and licensed under the state's lift rules before use and inspected periodically by the designated inspecting authority. Aaditya Interior recommends that the lift company's layout drawing is obtained before structural drawings are finalised, not after the shaft is cast.

What lifts cost

Lift prices vary with capacity, number of stops, speed, drive type, door type, car finish and brand. The ranges below are indicative October 2026 figures for supply and installation of the lift equipment only. They exclude civil work for the shaft and pit, electrical supply up to the lift panel, and taxes, and should be confirmed with quotations from licensed lift companies.

Running costs are modest compared with purchase cost but should not be ignored: electricity, the annual maintenance contract, periodic statutory inspection fees, and eventual modernisation after the controller and machine reach the end of their useful life. An automatic rescue device, which brings the car to the nearest landing and opens the doors during a power failure, is widely specified in Indian residential lifts and is worth including at purchase.

Civil readiness checklist before installation

• Obtain the licensed lift company's layout drawing before structural design, and design the shaft, pit and overhead to it.
• Keep shaft clear sizes and plumb within the lift company's tolerance from pit to top; check at every floor.
• Waterproof the pit, keep it dry, and provide a pit ladder and light point as per the lift company and code.
• Provide the hoisting hook or beam at the shaft top and any machine room with safe access, as specified.
• Keep the shaft free of water pipes, drains, gas lines and unrelated cables.
• Provide a dedicated power supply, earthing and lighting to the lift panel through the electrical consultant.
• Plan landing lobbies at least about 1500 mm deep, larger for multiple lifts and stretcher cars.
• Confirm accessible, stretcher and fire-lift needs with NBC 2016 and the local authority before finalising the core.
• Do not use the lift until it is registered, inspected and licensed as required by the state's lift rules.

Frequently asked questions

What is the standard lift size for an 8-person lift?

Typical planning figures are a car of about 1100 × 1400 mm or 1300 × 1100 mm, a shaft of about 1800–1900 × 1900–2100 mm and an 800 mm clear door. The exact sizes depend on the manufacturer's layout and must be confirmed before the shaft is designed.

What is the minimum lift shaft size for a home lift?

Compact home lifts typically need a shaft of about 1200 × 1200 to 1500 × 1500 mm, a shallow pit and an overhead of about 2500–2900 mm. Pneumatic and screw-driven designs can fit smaller spaces but carry fewer people.

How deep should a lift pit be?

For a typical 1.0 m/s passenger traction lift, about 1200–1500 mm; faster lifts need more. Home lifts often need only 50–300 mm. The lift company's drawing sets the exact figure.

Which code covers lifts in India?

The National Building Code of India 2016, Part 8 (Building Services), Section 5, covers installation of lifts, escalators and moving walks, together with Indian Standards for electric traction lifts and related equipment. Part 4 covers fire lifts and Part 3 accessibility. State lift rules govern licensing and inspection.

How much does a lift cost for a G+4 building?

Indicatively in October 2026, a 6–8 person machine-room-less passenger lift for a G+4 building costs about ₹12–22 lakh for supply and installation, excluding civil work, electrical supply and taxes. Annual maintenance is extra.
