Joint Development in Bangalore Real Estate: A Comprehensive Guide for Homebuyers

Joint Development Agreements (JDAs) have become the foundation of Bangalore’s real estate growth, especially for residential projects. In fact, according to Hindustan Times, as of 2024, about 70% of real estate assets in Bengaluru (across residential and commercial segments) have been developed through JDAs. 

Recently at Propsoch, we’ve been getting a lot of questions from homebuyers trying to understand this model, basically what it means, whether it’s safe and how it affects their purchase. 

If you’ve been wondering the same, this blog is for you because the motive of this is to help demystify why a particular project is structured a certain way and assures you that it’s a very common practice, backed by legal safeguards.

To understand how joint development works, its benefits and risks and what to look out for when purchasing a home in such projects, read the complete blog.

What is Joint Development in Real Estate?

A Joint Development Agreement (JDA) in real estate is a legal contract where a landowner and a developer collaborate to develop a property without transferring land ownership upfront. 

The landowner contributes the land and the developer takes on the construction, financing and marketing of the project. Instead of a one-time land sale, both parties agree to share the benefits of the completed project, either in the form of built-up area (for example, a certain number of apartments) or revenues from the sale of units, as specified in the agreement. 

This essentially means the landowner retains an ownership stake in the project and in return typically receives either a share of the constructed units or a share of the profits from the project’s sales. 

This model allows landowners to monetize their land while still participating in the development gains and it allows developers to undertake projects without the heavy upfront cost of land purchase.

How Joint Development Agreements Work?

In practice, when a JDA is executed, several key elements are involved:

• Sharing Ratio: The landowner and developer agree on a ratio to split the developed property or revenues. In Bangalore, it’s common to see ratios like 40:60 or 50:50 (landowner : developer). 
  • For instance, a 60:40 JDA means the landowner might get 60% of the constructed area (or equivalent revenue share) and the developer 40%. The exact split depends on factors like land value, project size and negotiation. 
  • Prime urban land can command a higher share to the owner, whereas in outskirts the owner’s share may be lower. 
• Area Share vs Revenue Share Models: There are two primary JDA structures:
  • Area Sharing JDA: The landowner receives a certain percentage of the built-up area in the completed project. For example, if a landowner is entitled to 30% area share, they will get 30% of the constructed flats (or villas, etc.).
  • Revenue Sharing JDA: The landowner is entitled to a fixed percentage of the revenue from sales of the project. For instance, an owner might get say, 35% of all apartment sales proceeds.
    • In some cases, hybrid arrangements exist but area-sharing is particularly common for residential apartment developments in Bangalore.
• Legal Agreement and Title: The JDA is a formal, registered contract and in Karnataka, JDAs must be registered with the Sub-Registrar and stamp duty is payable (typically a nominal percentage of the land value, capped to a certain amount) to make it legally binding.
  • Along with the JDA, usually a Power of Attorney (PoA) is executed where the landowner authorizes the developer to represent them for necessary project tasks.
    • This PoA lets the developer obtain plan sanctions, environmental clearances, sell units and sign sale deeds on behalf of the landowner.
  • Essentially, the developer gets the legal right to carry out and sell the project while the landowner remains the titular owner of land until units are sold.
• Approvals and Responsibilities: The developer takes on obtaining all approvals (building plan sanction from BBMP/BDA, environmental clearances, RERA registration, etc.), project financing, construction, and marketing of the project. 
  • The landowner typically does not invest money (other than the land itself) or involve in day-to-day development though they may monitor progress. 
  • All development costs are borne by the developer, which is why the developer’s share is usually larger than the landowner’s in area-sharing models.
• Deliverables to Landowner: Depending on the JDA terms, once the project is completed, the landowner receives their share, either physical units (flats, villas, plots) or proceeds from unit sales. 
  • In an area-sharing deal, specific units (of equivalent agreed area) are allotted to the landowner, often detailed in an annexure to the agreement. 
  • In a revenue-sharing deal, the landowner’s share of money might be paid in tranches as sales happen, as defined by the agreement.
  • Many JDAs in Bangalore also involve the developer paying an upfront deposit to the landowner at the time of signing, sometimes called goodwill or signing amount.

Why Joint Development is Popular in Bangalore?

Bangalore’s real estate market has embraced joint development model more than perhaps any other city in India. Rapid urbanization and land scarcity in prime areas have made JDAs a preferred model. Here are some key reasons:

• Increasing Land Prices: Land prices in Bangalore have surged significantly in recent years (rising ~20-30% in just the last three years in many localities). 
  • For developers, buying large land parcels outright has become prohibitively expensive. Instead of paying tens of crores to buy a plot, a builder can enter a JDA, invest that money into construction and pay the landowner via profit/area share.
• Rapid Urban Development and Supply of Housing: To meet the rapid housing demand from IT professionals and migrant populations, developers leverage this model.
  • Without JDAs, developers might struggle to assemble land in prime areas and many iconic apartment complexes or villa communities simply wouldn’t exist.
• Risk Sharing and Capital Efficiency for Developers: From the developer’s perspective, joint development greatly reduces the initial capital burden and risk.
  • Instead of tying up capital in land, the developer can do more projects with the same funds. 
  • This capital-efficient approach to growth is explicitly part of many developers’ strategies. For example, renowned A grade developer recently entered a ₹1000 crore JDA for a project in East Bengaluru, stating that “this project, structured under a JDA, reflects our capital-efficient approach to growth”. 
• No Immediate Tax for Landowners: There’s even a tax incentive that makes JDAs attractive. Under Section 45(5A) of the Income Tax Act in India, individual or HUF landowners in a JDA don’t incur capital gains tax until they actually receive the project’s completion (i.e. when their share of flats or revenue is handed over).
  • In a straight land sale, the seller would owe capital gains tax in the year of sale. But in a JDA, the tax is deferred until the project is completed/units given, which could be several years later.

Before 2020, outright land sales were more common but with regulatory changes and price escalations, the JDA model now dominates new projects. It is a trend born out of necessity (land cost) and opportunity (higher returns), which is aligning well with the interests of both landowners and developers in the region.

Legal Framework for Joint Development Projects: What Homebuyers Should Know

Joint development projects come with a specific legal structure and as a homebuyer, you don’t need to understand every clause between the landowner and the developer but you do need to know how this structure affects your purchase, your rights and your protection under law.

1. Start by Checking the Project on the Karnataka RERA Website

The first step is always to check the project on the Karnataka RERA site.

Look for:

• RERA registration number
• Project status
• Names of promoters

In most JDAs:

• Both the developer and the landowner appear as co-promoters.

If only the developer is listed, it’s not automatically a red flag but ask for clarity so you understand how rights are structured.

When the landowner is listed, you get added protection because you can legally hold both parties responsible if something goes wrong.

2. Verify Land Title and the JDA Structure

You don’t need to read the full JDA, but your lawyer should verify:

• The landowner actually owns the land and the title is clear
• The JDA and Power of Attorney (PoA) are registered
• The developer has clear, documented rights to develop and sell
• The unit allocation (developer-share vs landowner-share) is properly recorded

This is especially important if you're buying a landowner-share unit because each flat in a JDA project is pre-assigned internally.

Your lawyer should also review:

• The Encumbrance Certificate (EC)
• Any existing mortgages or dues
• Whether the landowner has sale restrictions (common in some JDAs where landowners can sell only after certain stages)

3. Buying From a Developer vs Buying From a Landowner

Both are safe if documentation is correct but the process is slightly different when buying from a landowner.

a) Payment Schedule

Avoid big upfront payments.Follow a standard construction-linked plan, just like buying from the developer.

This protects you if:

• construction slows
• a dispute arises
• approvals get delayed

Where possible, route payments through the project escrow account or ensure the developer formally acknowledges payments.

b) Tripartite Agreement / NOC

Never buy a landowner unit without the developer formally acknowledging your purchase.

This usually happens through:

• a tripartite agreement, or
• a developer-issued NOC

This ensures:

• the developer takes full responsibility to construct and hand over your unit
• they’re aware of the sale
• there’s no confusion later about obligations or rights

c) Outstanding Construction Dues

In some JDAs, landowners must pay the developer for construction of their share of units.

If the landowner hasn’t paid their portion:

• the builder may withhold possession
• disputes can arise at the end

So confirm:

• whether any construction dues are outstanding
• and ensure your payments to the developer clear all dues tied to your unit

This eliminates handover issues.

4. Amenities, Handover & Association Formation

As the project nears completion, both the landowner and the developer must hand over documents to the Residents’ Association, including:

• land title documents
• approvals and sanction plans
• completion certificates

Just ensure both sides are cooperating, especially if the landowner still holds unsold units.

5. Construction Quality and Accountability

Regardless of whose share you buy from, construction responsibility is with the developer.

Ensure your agreement clearly mentions:

• the developer is responsible for construction
• all units follow the same specifications
• defect liability applies as per RERA

This must reflect clearly even in landowner-unit agreements.

6. Home Loans and Bank Approvals

Banks in Bangalore work with JDA projects regularly.

For buyers:

• Loan processing is normal
• Banks may ask for the JDA or the NOC as extra documents
• Choosing a bank that has pre-approved the project makes the process smoother

Pros and Cons of Joint Development (From a Homebuyer’s Perspective)

How Joint Development Helps Homebuyers

1. More Housing Supply in Good Locations: JDAs are one of the reasons you see so many new apartment projects in established parts of Bangalore.

• Land that would otherwise lie unused (or be held by families who don’t want to sell) gets developed.
• This means more projects in already livable, well-connected areas and not just on the outskirts.
• Many popular apartment complexes in Bangalore exist only because the landowner chose a joint development instead of holding on or selling outright.

2. Access to Land That Wouldn’t Otherwise Be Sold: A lot of land in Bangalore is owned by families who don’t want to “let go of the land” emotionally.

For such owners, a JDA feels more comfortable than an outright sale because:

• they stay involved,
• they get finished flats instead of cash.

For buyers, this means projects come up on privately held land that might never have reached the market if JDA wasn’t an option.

Risks and Practical Concerns for Homebuyers

1. Project Delays if Partners Fall Out: The biggest risk in a JDA project is relationship breakdown between landowner and developer.

• If the developer runs into funding issues or approvals get stuck, the project can slow down.
• If there’s a dispute over sharing extra FSI, quality, or money, it can land in court.
• When that happens, construction can stall, and your money stays locked in.

This is one extra layer of risk compared to a project where the developer also owns the land outright.

What you can do: Stick to developers with a track record and check RERA status and progress before making big payments.

2. To You, It May Seem, More Parties Means More Complexity: In a JDA project, you might see:

• units sold by the developer, and
• units sold by the landowner (often at a discount).

For you, this can mean:

• your sale agreement may have multiple parties (developer + landowner), or
• extra paperwork like a tripartite agreement or NOC from the builder if you’re buying a landowner-share flat,
• slightly more back-and-forth between your bank, the seller, and the builder.

Legally, you still end up with:

• one flat + undivided share of land.
• It’s just that the path to get there has more steps, so you need better legal support and slower, careful checking of documents.

3. Higher Dependency on Landowner’s Financial & Legal Health: If the landowner:

• is in financial trouble,
• gets dragged into a legal case,
• or refuses to cooperate mid-way,

It can create complications around:

• title clarity,
• handover of documents,
• or refunds (in extreme situations like project cancellation).

These are edge cases, but as a buyer, you should at least know that the landowner’s situation and attitude can affect the project.

4. Disputes Around Unit Allocation: The JDA should clearly define how many sq.ft. or which specific flats go to the landowner and which go to the developer.

If this is not crystal clear or gets disputed later, it can lead to:

• fights over who “owns” a particular unit,
• delays in registration or possession,
• confusion if you booked a unit that suddenly gets contested between the two.

This is why: If you’re buying a landowner-share unit, make sure:

• your lawyer checks that this flat is officially part of the landowner’s allocated share, and
• the developer gives a written NOC or becomes a confirming party in your agreement.
