Turnkey Fit-Out Contractor
in Mumbai
IBS is a turnkey fit-out contractor in Mumbai, headquartered in Goregaon West and operating from the city for more than fifteen years. Its own design team, engineers and workmen cover civil, MEP, fire fighting, HVAC, interiors and furniture, so a Mumbai office, hotel or hospital floor is designed in-house or built to your architect’s drawings under one contract. Mumbai adds its own rules: Maharashtra’s fire safety law, several power utilities, and a monsoon from June to October.

What changes when a fit-out is built in Mumbai?
Three things. Fire safety is the owner’s or occupier’s legal duty under Maharashtra’s 2006 fire safety Act, and fire NOCs are issued by the Mumbai Fire Brigade. Power comes from one of several licensees, so extra load for HVAC is applied for to the right one early. And the monsoon, June to October, shapes when terrace and outdoor work can happen. IBS plans all three into the programme.
What is a turnkey contractor?
A contractor that takes a space from bare shell to ready for use under one contract: civil, MEP, fire fighting, HVAC, interiors, furniture and finishes, with one project lead and one programme. In Mumbai, IBS can also design the space with its in-house team, or build an architect’s design as drawn.
What is a fire NOC?
A no-objection certificate from the fire authority, confirming that a building or premises meets fire safety requirements. In Greater Mumbai it is issued by the Mumbai Fire Brigade. The owner or occupier applies for it; the contractor supplies the installation records it needs.
What is sanctioned load?
The electrical load a connection is approved to draw, set by the distribution licensee. A fit-out that adds air conditioning, a server room or a kitchen can exceed it, and the consumer then applies to its licensee for additional load.
Rules
Which Mumbai rules apply to a commercial fit-out?
Stated as principles, because the detail changes. Every permission below is the client’s to obtain; IBS can help with the paperwork and liaison, charged separately.
Fire safety in Maharashtra
- The Maharashtra Fire Prevention and Life Safety Measures Act, 2006 puts fire safety on the building’s owner, or its occupier where the owner cannot be traced: obtain fire safety approval from the Chief Fire Officer, provide the measures it sets, and keep them in good repair
- In Greater Mumbai the fire authority is the Mumbai Fire Brigade, part of the Municipal Corporation of Greater Mumbai, which issues fire NOCs
- Fit-out changes to sprinklers, detection or compartments should be checked against the building’s fire approval, with the owner’s or landlord’s sign-off first
Power supply
- Mumbai has more than one electricity distribution licensee: BEST in the island city, Adani Electricity in the suburbs, Tata Power across both, and MSEDCL in parts of the eastern suburbs such as Bhandup and Mulund
- New HVAC, kitchens or server rooms can take a floor past its sanctioned load; the consumer applies for additional load to its own licensee, which must accept the application on paper or online
- IBS’s design team calculates the connected load for your fit-out, so your application can be made before the equipment arrives
Building and landlord permissions
- Commercial towers and malls set their own fit-out rules: drawings for approval, working hours, service-lift bookings, hot-work permits and deposits
- Licences, permits and NOCs are yours to obtain; IBS can prepare application drawings and handle liaison as a separately charged service
- Structural changes, new shafts and facade openings need the building owner’s structural consultant, not just the tenant’s approval

Mumbai
Why hire a turnkey contractor based in Mumbai?
A contractor based in the city it builds in plans around that city’s working rules from the first site visit.
Planning for Mumbai conditions
- The monsoon normally runs from 11 June to 8 October: terrace work, outdoor units, roof penetrations and external pipework are planned for the dry months
- Mumbai’s air is humid through the year: mean morning humidity is 83% at Colaba and 75% at Santacruz, and about 90% at Colaba from July to September (IMD), so coatings, stainless fixings and coil protection are offered as options for outdoor equipment
- Much of the work happens inside occupied towers, so noisy and dusty work is scheduled around the building’s rules and neighbours
- Material movement is booked around service lifts, loading bays and city traffic, not assumed
What IBS’s Mumbai base changes for you
- Head office in Goregaon West; furniture and joinery made at IBS’s factory near Vasai East, north of the city
- Site teams, procurement and the project lead are run from Mumbai, not flown in for the job
- An in-house design team for every discipline, and IBS’s own engineers and workmen for civil, MEP, fire fighting, HVAC, interiors, painting and furniture
- On an architect-led project IBS builds the architect’s design; where there is no architect, its design team prepares the drawings
- Approved vendor at Adani Airports, HDFC ERGO, Reliance Retail, Godrej Finance, EPSON, Duravit, HSBC, Tata CLiQ, Canon, Aditya Birla Fashion and Retail and HDFC Life

Market
How much office fit-out work is there in Mumbai in 2026?
Figures from named sources, read on 29 September 2026. They set the context for budgets and programmes; they are not IBS prices.
Office demand and cost
- Mumbai recorded 11.6 million sq ft of gross office leasing in 2025 (JLL, 2026)
- A collaborative hybrid office fit-out costs about ₹6,567 per sq ft in Mumbai, the highest of India’s major office cities (Cushman & Wakefield, 2026)

Public work in Mumbai
- The Mumbai Port Authority’s 2026 office renovation tender bundles interiors, furniture, HVAC, fire fighting and electrical into one ₹10.50 crore package, excluding GST, and asks for a registered office in the Mumbai Metropolitan Region
- Public tenders like this one are open to contractors who meet their eligibility criteria, which is why a Mumbai office and documented similar work matter
Commercials
How is a Mumbai fit-out priced?
What sits in the quotation, what sits outside it, and what to check before you compare two numbers.
How the price is built
- A site survey before the quotation, then a line-item BOQ against the GFC drawings, not a single rate per square foot
- Design by IBS’s team, where you need it, quoted as its own line
- Liaison with the fire authority, the licensee or the landlord quoted separately, and only if you want it
- Night and weekend working, service-lift charges and site protection listed, not buried in rates

Materials and equipment
- Materials and equipment are your choice: IBS sets out options against your budget and you decide
- Nothing is substituted from the approved option without your written approval
- Manufacturer warranties on equipment passed through to you
What to check in any Mumbai quotation
- Are fire, power and landlord approvals listed as your responsibility, with any liaison priced as its own line?
- Does the programme show the monsoon, service-lift slots and the landlord’s working hours?
- Are testing and commissioning included, with the records you will receive listed?
- Is the defect liability period stated, and who answers a snag after handover?
Quality
How is a Mumbai fit-out checked before handover?
Leaks and services faults often surface in the first monsoon or the first full week of occupation. These checks are there to find them first.
Before the ceiling closes
- Shop drawings approved before fabrication, and mock-ups or sample areas where the contract asks for them
- Pipework pressure tested and electrical circuits insulation tested before anything is hidden
- Services checked against the coordinated drawing, so ducts, sprinklers, trays and lights are where they were agreed
- Terrace and wall penetrations sealed and checked before the monsoon
At handover
- Test certificates, as-built drawings and O&M manuals in one handover file
- A closed snag list, walked with your facility team
- Twelve months on installation, with manufacturer warranty passed through
- The defect liability period your contract sets, with a named person who answers snags after handover

Request a scoped BOQDesign and build, build only, or separate contractors: which suits a Mumbai fit-out?
The right route depends on whether you already have an architect and how many contracts you want to manage.
| IBS designs and builds | IBS builds your architect’s design | Separate trade contractors | |
|---|---|---|---|
| Who designs | IBS’s in-house design team | Your architect | Your architect |
| Contracts you manage | One | One | One per trade |
| Who resolves a clash between trades | IBS’s project lead | IBS’s project lead, against the architect’s drawings | The architect or you, between contractors |
| Best for | Clients without an architect who want one party accountable | Architect-led offices, hotels and hospitals | Clients with their own project team who want to buy each trade |

Questions Buyers Ask
Frequently asked questions
Which turnkey contractors work in Mumbai?
Many firms describe themselves as turnkey contractors in Mumbai, and we have not found a neutral ranking. Check who does each trade in-house, similar Mumbai projects you can visit, the largest single order the contractor has executed, and how it handles fire and power approvals. IBS is headquartered in Goregaon West, with its own design team and trades.
What is a turnkey contractor?
A contractor that takes a space from bare shell to ready for use under one contract, covering civil, MEP, fire fighting, HVAC, interiors, furniture and finishes, with one project lead. IBS works turnkey in Mumbai either by designing the space with its in-house team or by building your architect’s design.
Does IBS design as well as build?
Yes. IBS has an in-house design team for every discipline, so it can design a Mumbai fit-out and build it under one contract. Where your architect has already designed the project, IBS builds that design as drawn, raising shop drawings and written queries rather than redesigning it.
How much does an office fit-out cost in Mumbai?
Cushman & Wakefield’s 2026 guide puts a collaborative hybrid office fit-out at about ₹6,567 per sq ft in Mumbai, the highest of India’s major cities. Your cost depends on the specification, MEP scope, furniture and the state of the shell, which is why IBS quotes a line-item BOQ against your drawings.
Who obtains the fire NOC for a Mumbai fit-out?
The owner or occupier. In Greater Mumbai the Mumbai Fire Brigade issues fire NOCs, and fit-out changes to sprinklers, detection or compartments have to fit the building’s fire approval. IBS hands over the installation records and test certificates, and can handle liaison as a separately charged service.
What does Maharashtra’s fire safety law require of an occupier?
The Maharashtra Fire Prevention and Life Safety Measures Act, 2006 makes the owner or occupier responsible for obtaining fire safety approval, providing the fire prevention and life safety measures it sets, and keeping them in good repair. A fit-out that changes sprinklers, detection or compartments has to keep the building within that approval.
Will my Mumbai fit-out need more electrical load?
Often, if it adds air conditioning, a server room or a kitchen. The consumer applies for additional load to its own distribution licensee, which in Mumbai may be BEST, Adani Electricity, Tata Power or MSEDCL depending on location. IBS’s design team calculates the connected load early so the application is not left until the equipment arrives.
Can a fit-out run through the Mumbai monsoon?
Yes, indoors. The normal monsoon runs from about 11 June to 8 October, so IBS plans terrace work, outdoor units, roof penetrations and external pipework for the dry months and keeps interior work moving through the rains.
Can IBS work in an occupied Mumbai tower?
Yes. In an occupied building, IBS plans noisy and dusty work around the building’s working hours, books service lifts and loading bays in advance, and follows the landlord’s hot-work and permit rules.
Who obtains landlord and society approvals?
You do, as the tenant or owner. Commercial towers and malls in Mumbai may ask for fit-out drawings, working-hour commitments, deposits and permits before work starts. IBS can prepare the drawings and handle liaison with the building management as a separately charged service.
Where does IBS make furniture and joinery for Mumbai projects?
At its own factory near Vasai East, north of the city. Joinery is made to the site’s measured dimensions and installed by IBS’s own team, rather than bought in from a separate supplier.
Has IBS delivered fit-outs in Mumbai?
Yes. Named Mumbai work includes GroupM’s Mumbai office, covering interior fit-out, MEP works and office branding. WeWork Mumbai’s interiors were delivered by IBS’s sister company, RKS Interior. IBS has operated in Mumbai for more than fifteen years.
What is the largest project IBS has executed?
IBS’s largest single order executed to date was worth ₹25 crore. Large projects run through the same in-house teams under one project lead, with progress reported to the PMC or client against the programme.
Can IBS work at Mumbai airport?
IBS is BCAS-cleared to work across the entire airport premises, including airside areas such as bus gates and departure areas. Work inside a live terminal follows the airport operator’s access, working-hour and permit rules.
Is IBS an approved vendor for large companies?
Yes. IBS is an approved vendor at Adani Airports, HDFC ERGO, Reliance Retail, Godrej Finance, EPSON, Duravit, HSBC, Tata CLiQ, Canon, Aditya Birla Fashion and Retail and HDFC Life.
How are materials chosen?
You choose. IBS sets out options against your budget and the design, such as laminate or veneer joinery, vitrified tile, carpet or epoxy floors, and gypsum or grid ceilings, you or your architect decide, and nothing is substituted without written approval. Manufacturer warranties on equipment are passed through to you.
How long does a Mumbai office fit-out take?
It depends on area, scope and approvals. The programme is worked back from your move-in date and shows the landlord’s approval period, long-lead equipment, the monsoon for any outdoor work, and service-lift slots. IBS confirms it at quotation against your drawings.
What warranty does IBS give?
Twelve months on installation from handover, with manufacturer warranties on equipment passed through. The defect liability period your contract sets governs how snags after handover are put right, and IBS names the person who answers them.
Does IBS work outside Mumbai?
Yes. IBS delivers fit-outs across India, including Pune, Delhi NCR, Bengaluru and Hyderabad, with site teams and procurement run from its Mumbai head office.
How do I get a quote for a Mumbai fit-out?
Send the address, the area, your drawings if you have them, and your move-in date through the enquiry form, WhatsApp or email. IBS will arrange a site visit and send a line-item BOQ, with design, if you need it, quoted as its own line.
