1. What Is FAR?
FAR stands for Floor Area Ratio. It is the ratio between the total built-up area of a building and the total area of the plot on which it stands.
In simple words, FAR tells you how much construction is allowed on a piece of land. The higher the FAR, the more floors you can build. The lower the FAR, the less you can construct.
It is one of the most important numbers in real estate — for buyers, builders, and investors alike.
2. FAR and FSI — Are They the Same?
Yes. FAR (Floor Area Ratio) and FSI (Floor Space Index) mean exactly the same thing.
Different states just use different names for the same concept.
FSI is more commonly used in Maharashtra, Karnataka, and Tamil Nadu. FAR is used in Delhi, Uttar Pradesh, Haryana, and most other states.
If someone says FSI 2.0 or FAR 2.0, they are saying the same thing.
3. The Formula
FAR = Total Built-up Area ÷ Plot Area
Or to find out how much you can build:
Maximum Built-up Area = FAR × Plot Area
Example:
You own a plot of 1,000 sq ft. The local authority allows a FAR of 2.0.
Maximum built-up area = 2.0 × 1,000 = 2,000 sq ft
This means you can construct up to 2,000 sq ft of floor area on your 1,000 sq ft plot — across however many floors the height regulations allow.
4. Why Does FAR Matter?
FAR directly controls how much a developer can build — and that controls the project’s entire economics.
More FAR means more units, more sales, more revenue. Less FAR means fewer units and lower revenue potential.
For a buyer, FAR affects density — how many people live in the same building or complex. A project built at maximum FAR will typically be denser than one built at lower utilisation.
For an investor, FAR is a value driver. Land in a high-FAR zone is worth far more than the same-sized land in a low-FAR zone — because you can build more on it.
5. Who Decides FAR?
FAR is set by the local development authority through the Master Plan or Development Plan for that city or zone.
Examples:
- In Delhi, the Master Plan (prepared by DDA) sets FAR limits zone-wise
- In Mumbai, the Development Control and Promotion Regulations (DCPR) set FSI limits ward-wise
- In Bengaluru, the Revised Master Plan (RMP) sets FAR by zone type
- In Lucknow and Kanpur, the Lucknow Development Authority and Kanpur Development Authority set FAR under the UP Master Plan
FAR is not the same across a city. It varies by zone — residential, commercial, industrial, mixed-use — and sometimes by road width in front of the plot.
6. FAR by Zone Type — A General Picture
| Zone Type | Typical FAR Range |
| Residential (low density) | 1.0 to 1.5 |
| Residential (high density) | 1.5 to 3.0 |
| Commercial | 2.0 to 4.0 |
| Mixed-use | 2.5 to 4.0 |
| Industrial | 1.0 to 1.5 |
| TOD Zones (near metro) | 3.0 to 4.0+ |
These are general ranges. Actual FAR depends on the specific city, zone, and local regulations.
7. Base FAR vs Premium FAR
Many states now offer two layers of FAR — a base (free) FAR and a premium (paid) FAR.
Base FAR is the construction allowed as a right — no extra payment needed.
Premium FAR (also called Paid FSI or Fungible FSI in Maharashtra) allows the developer to build more by paying an additional charge to the government.
This system lets builders go higher on well-located plots while generating revenue for the government. It also increases the overall supply of housing in premium areas.
In Mumbai, the concept of fungible FSI under DCPR 2034 allows developers to purchase additional FSI over and above the base limit — making it one of the most flexible FSI regimes in India.
8. Transferable Development Rights (TDR)
TDR (Transferable Development Rights) is closely linked to FAR.
When a landowner gives up part of their land for a public purpose — like a road widening or a school — the government compensates them with development rights certificates. These certificates can be used to build extra floors on a different plot or sold to another developer who needs additional FAR.
TDR effectively allows unused FAR from one location to be transferred and used on another plot — within the rules set by the local authority.
It is widely used in Mumbai, Pune, Nashik, and Bengaluru.
9. FAR and Road Width
In many cities, the FAR you are allowed depends on the width of the road in front of your plot.
A plot on a wider road gets a higher FAR. A plot on a narrow lane gets a lower FAR.
The logic is simple — more construction means more people, more vehicles, and more load on infrastructure. A wider road can handle that better.
This is why corner plots and plots on main roads are priced higher. They often attract better FAR utilisation.
10. FAR in RERA and Building Approvals
When a developer registers a project on the state RERA portal, the approved FAR and sanctioned plan must be disclosed.
This means buyers can verify:
- How many times has the developer been sanctioned
- Whether the number of floors matches the approved FAR
- Whether any additional premium FAR has been purchased
If a developer constructs beyond the sanctioned FAR without approval, the excess construction is illegal — it can be sealed, demolished, or penalised by the local authority. Buyers in such projects face enormous risk.
Always check the building plan approval and sanctioned FAR before buying in a new project.
11. How FAR Affects Property Prices
Higher FAR = More units on the same land = Lower per-unit land cost = More affordable pricing
Lower FAR = Fewer units = Higher per-unit land cost = Higher pricing
This is why luxury low-rise developments — which deliberately use only a fraction of the permitted FAR — are priced significantly higher per sq ft than dense high-rise projects on similar land.
FAR also affects resale value. If the government increases FAR in an area, land values in that zone rise immediately, because developers can now build more on the same plot.
Announcements of FAR increases in TOD zones (Transit-Oriented Development zones near metro stations) have historically triggered rapid land price appreciation in those corridors.
12. FAR Across Major Indian Cities
| City | Governing Authority | Typical Residential FAR |
| Mumbai | MCGM under DCPR 2034 | 1.0 (base) + premium FSI |
| Delhi | DDA Master Plan 2041 | 1.2 to 3.5 by zone |
| Bengaluru | BBMP under RMP | 1.75 to 3.25 |
| Chennai | CMDA under CMDA Regulations | 1.5 to 2.5 |
| Hyderabad | HMDA under GO 168 | 1.6 to 3.6 |
| Pune | PMC under DCPR | 1.1 (base) + premium |
| Ahmedabad | AMC under GDCR | 1.8 to 2.4 |
| Lucknow | LDA Master Plan | 1.5 to 2.5 |
Note: These are indicative ranges. Actual FAR depends on specific zone, road width, and current regulations. Always verify with the local development authority.
13. A Simple Example
Suresh owns a 500 sq mt plot in a residential zone of Hyderabad. The applicable FAR is 2.5.
Maximum built-up area = 2.5 × 500 = 1,250 sq mt
The height regulations allow up to 5 floors. Suresh plans to build a ground floor plus 4 floors — each of 250 sq mt. Total = 1,250 sq mt. He is at exactly his FAR limit.
A neighbouring plot with the same size but located in a commercial zone with FAR 3.5 can build up to 1,750 sq mt — 500 sq mt more on identical land. That extra construction potential is exactly why the commercial plot is worth more.
14. Tips for Buyers and Brokers
- Always check the approved FAR before buying in a new project — Verify the building plan approval and sanctioned FAR on the RERA portal. Extra floors built beyond the approved FAR are illegal and at risk of demolition.
- Understand FAR when evaluating land for investment — Land value is largely a function of how much you can build on it. Two identical plots in different FAR zones can have very different values.
- Monitor FAR revision announcements — When the government revises FAR upward in a zone — especially in metro corridors or TOD zones — land prices move quickly. This is one of the earliest indicators of price appreciation.
- Check road width before calculating FAR — In cities where FAR is linked to road width, a plot on a wider road allows more construction. Confirm the road width officially — not visually.
- Verify premium FAR purchase separately — If a developer claims to have purchased premium FAR, verify the documentary proof. Premium FAR must be documented and disclosed on the RERA portal.
15. Common Mistakes to Avoid
Confusing FAR with the number of floors
FAR limits total built-up area — not the number of floors directly. You can achieve the same FAR with fewer tall floors or more shorter ones. Height is governed by separate regulations. Both apply together.
Assuming FAR is uniform across a city
FAR varies significantly by zone, road width, and land use type. Never assume the FAR in one part of a city applies to a plot in another part. Always verify with the development authority.
Buying into projects that have used unapproved FAR
Some developers build extra floors hoping to regularise later. This is a serious legal risk for buyers. Any floor built beyond the sanctioned FAR can be ordered for demolition — regardless of how many people have bought units there.
Not factoring in FAR when pricing land
Brokers who price land purely on area without considering FAR are systematically undervaluing or overvaluing. A 1,000 sq ft plot with FAR 3.0 has far more development potential — and therefore market value — than an identical plot with FAR 1.0.
Ignoring FAR changes during resale
If the government has increased FAR in an area since the building was constructed, the existing building may be under-utilising the plot’s full potential. This often creates redevelopment opportunities — and affects resale pricing for both the building and the underlying land.
16. FAQs
What is FAR in real estate?
FAR (Floor Area Ratio) is the ratio of a building’s total built-up area to the area of the plot it stands on. It is set by the local development authority and determines the maximum construction allowed on any given plot.
What is the difference between FAR and FSI?
They are the same thing. FAR (Floor Area Ratio) is used in Delhi, UP, and most North Indian states. FSI (Floor Space Index) is used in Maharashtra, Karnataka, and Tamil Nadu. Both express the same concept — how much you can build relative to plot size.
How is FAR calculated?
FAR = Total Built-up Area ÷ Plot Area. To find the maximum allowed construction: Maximum Built-up Area = FAR × Plot Area.
Who sets the FAR for a city?
The local development authority sets FAR through the city’s Master Plan or Development Control Regulations. Examples include DDA for Delhi, MCGM under DCPR for Mumbai, and BBMP under the Revised Master Plan for Bengaluru.
Can a developer build beyond the permitted FAR?
No. Any construction beyond the sanctioned FAR is unauthorised. It can be sealed or demolished by the local authority. Buyers in such buildings face severe legal and financial risk.
What is premium FAR or paid FSI?
Premium FAR is additional construction permission granted by the government over and above the base FAR — in exchange for payment of a premium charge. It allows developers to build more on a plot while the government earns revenue. It is widely available in Maharashtra (fungible FSI) and several other states.
In Simple Words, FAR tells you how much you are allowed to build on a piece of land. More FAR means more construction, more units, and more value from the same plot. Less FAR means fewer units and lower density. Whether you are buying a flat, investing in land, or evaluating a project, always check the FAR. It is the single number that drives construction potential, land value, and project economics.
