The cost of buying office space in Mumbai involves more than just the sticker price. Many buyers look only at the basic property rate. They face big money surprises later.
A full office budget covers many items. You must pay the base price, state stamp duty, and government registration fees. You also need to pay taxes, building maintenance deposits, and parking fees. Interior setup work will add to this total as well.
Planning for these costs early keeps your company’s cash safe. It helps you buy the right office without any stress.
Average Base Price by Business Hub
Office rates across Mumbai change by location. Prime hubs cost more because of high demand and limited land. Suburbs and outer hubs cost less. They give growing companies more space for their money.

| Business Hub | Hub Type | Average Rate (per sq ft carpet) | Common Business Use |

Factors That Change the Base Price
Rates within the same neighborhood can still differ. Several clear factors move the base price up or down:
- Building Age and Quality: Newer buildings with modern glass walls and fast elevators charge more. Older buildings charge lower rates per square foot.
- Floor Level: Higher floors usually cost more money. They bring in more natural light and have less street noise. Many builders charge a small fee for every floor above the ground level.
- Road and Transit Access: Buildings right next to main highway links or metro lines command top rates. Buildings located deep inside narrow streets sell for lower prices.
- Unit Direction: An office that looks out over open ground or the main street costs more than an office that faces a side wall.
Government Taxes and Legal Charges
Buying an office space requires paying mandatory state taxes. These legal charges secure your ownership under the law. You must pay them directly to the state government during your purchase.
Stamp Duty and Registration
The state of Maharashtra collects stamp duty to make property deals legal. In Mumbai, buyers pay a stamp duty rate of 6% on commercial office sales. This includes a 5 percent base duty plus a 1 percent metro cess.
Unlike home purchases, commercial spaces offer no discount for female buyers. The tax is calculated on either the deal value or the official ready reckoner rate, whichever is higher.
The registration fee is fixed at a flat ₹30,000 on the official state portal for commercial properties valued above ₹30 lakh. For units below that amount, the fee is 1 percent of the total price.
Goods and Services Tax (GST)
The tax rules set by the Central Board of Indirect Taxes and Customs depend on the build status of the commercial building:
- Under-Construction Offices: Buyers pay an effective rate of 12% GST on under-construction office units. This applies to every construction installment paid to the builder.
- Ready Offices with OC: You pay 0 percent GST if the commercial building holds an Occupancy Certificate (OC). Buying an OC-received unit removes this tax completely from your budget.
Legal and Due Diligence Fees
Hiring an experienced property lawyer keeps your business safe from title flaws, hidden mortgages, and past debts. Standard legal verification costs in Mumbai range from ₹25,000 to ₹75,000.
This legal work covers three essential steps:
- Running a 30-year search through local registrar title records.
- Verifying bank non-objection certificates and clear land ownership.
- Reviewing the builder agreement terms before you pay your deposit.
Building and Maintenance Costs
Buying your office is only the first step. You must also pay regular building charges. These fees keep the lobby, lifts, and common areas clean and secure.
Common Area Maintenance and Advance Deposits
Common Area Maintenance (CAM) pays for shared spaces and daily services. It covers round-the-clock security, cleaning staff, lift repairs, and lobby lights.
In Mumbai commercial buildings, monthly CAM charges range from ₹15 to ₹50 per square foot of carpet area. Buildings with central air cooling and glass cleaning cost more.
Most societies also ask for advance deposits before you move in:
- Sinking Fund: A one-time cash pool to fix major building damage in the future.
- Advance Maintenance: Many builders collect 12 to 24 months of fees upfront. This helps them run the building during the first few years.
Car Parking Allocations
Parking space is tight across Mumbai. Most builders do not add car slots to the basic office price. You must buy or lease your slots on your own.
- Private Basement Slots: A private slot on the ground floor or basement costs ₹5 lakh to ₹12 lakh per car space in commercial towers.
- Mechanical Stack Parking: Many new towers use car lifts and stack systems to save room. These slots cost less, usually ₹3 lakh to ₹6 lakh each. Under MahaRERA parking rules, developers must clearly list the exact slot size and layout in your sale agreement.
Infrastructure and Utility Setup
You must pay one-time setup fees to link your office to city utilities. You pay these costs to the utility boards or the builder:
- Power Backup Fees: Commercial towers run large diesel power units. Work does not stop during power cuts. Builders charge a setup fee based on the power load your office needs.
- Water Connection Fees: A standard fee paid to the city council to link your private toilets and pantry lines.
- Property Tax Deposits: Many building societies collect advance funds to pay city property taxes on time.
Why You Must Verify Before You Pay
Buying an office takes a lot of company money. Checking state records before you pay keeps you safe from delays and court trouble.
How to Run a RERA Check on Commercial Property
Every office built over 500 square meters must register with the state body. Doing a RERA check on a commercial property proves the building has clear permits.
You can check any Mumbai office project online in four steps:
- Go to the MahaRERA portal.
- Click Registration and pick Registered Projects.
- Type the project name or its ID number.
- Read the project page to check three facts:
- Handover Date: Check the finish date. Look for past delays.
- Court Cases: Read the legal tab to see if anyone is suing over the land.
- Carpet Area: Make sure the room size on the state plan matches what the agent told you.e Western Express Highway for commutes toward the airport and BKC.
Why an Occupancy Certificate Saves Money
An Occupancy Certificate (OC) shows the tower is safe and built to code. Buying a space with an OC saves you cash:
- Zero GST: You pay no GST on an OC-ready room. This drops your tax bill right away.
- Keys on Day One: You move in now. You do not waste cash on rent while waiting for work to end.
- Easy Loans: Banks approve loans faster for towers that have an OC.

Plan Your Office Purchase
Buying an office is a major investment for your business. Look beyond the listed price and account for stamp duty, registration charges, GST where applicable, office setup, and ongoing maintenance costs. Planning these expenses helps you manage your budget.
Before finalising a property, verify the building’s approvals, carpet area, and Occupancy Certificate (OC). Review the legal documents carefully before making any payment.
