Buying Flat on Partial Land Parcels in Bangalore

By the Property Law Team | Legal Brigade | Bar Council of Karnataka

When a Bangalore apartment building sits on only part of a larger land parcel — with the developer retaining the balance land for future development, commercial use or sale — the flat buyer’s UDS is calculated only on the building’s portion of the land, and the retained land’s future development can affect light, ventilation, access and the overall value of the existing flats.

Why Do Builders Develop Only Part of a Larger Land Parcel in Bangalore?

Builders in Bangalore often acquire large land parcels and develop them in phases. Building Phase 1 on a defined portion and retaining the balance land for Phase 2, for commercial development alongside the residential project or for sale once the surrounding area’s value has risen is a common business model. This phased development is legitimate but creates specific legal complexity for Phase 1 buyers. Their UDS is calculated on the Phase 1 building’s land portion, and they have no automatic right over or connection to the retained balance land. The retained land’s future use directly affects their living environment.

The risks multiply when the builder does not clearly disclose which portion of the land parcel the building occupies. A buyer who assumes the entire parcel belongs to the project may later discover that the builder has sold the retained land to a third party for commercial construction, or that a mortgage on the entire parcel encumbers the building site as well. The legal separation between the building site and the retained land must be confirmed before any purchase commitment is made.

Large land parcel developments in Bangalore — particularly in corridor areas like Sarjapur Road, Whitefield and Devanahalli where builders acquired significant acreage — frequently have retained land that has been developed differently from what was marketed to Phase 1 buyers. Legal Brigade’s verification work on these projects finds that Phase 1 buyers rarely confirmed the retained land’s planned use at the time of purchase.

What Are the Specific Legal Risks When a Flat Building Is on Part of a Larger Parcel?

The following table summarises the primary legal risks that arise when a flat building occupies only part of a larger land parcel:

Each of these risks requires a specific verification step. The UDS risk is the most common misunderstanding — buyers who see a large parcel on the builder’s brochure assume their share extends across the whole parcel, when legally it extends only across the building site. The mortgage risk is the most serious — a bank holding a mortgage on the entire parcel may have a charge that extends to the building site, even if the building itself is not mortgaged separately. The easement risk is the most operationally damaging — if the building’s only access route passes through retained land that is later sold, the new owner can block the route.

How Do I Confirm What Portion of a Land Parcel the Building Occupies?

Follow these five steps to confirm the exact land portion your building occupies and the status of the retained balance:

1. Obtain the RERA registration for the specific building. The RERA disclosure should specify the exact land area of the building site as distinct from any larger parcel the developer owns. If the RERA registration only states the total parcel area without breaking out the building site, this is a red flag that the developer has not formally separated the two portions.

2. Obtain the building plan sanction from BBMP. This identifies the specific survey number and area on which the building is sanctioned. The building plan sanction is the definitive document that tells you exactly which land the building is approved to occupy.

3. Compare the building plan’s land area against the EC for the developer’s entire land holding. If the EC covers more land than the building plan, the developer has retained the balance. The difference between the two figures is the retained land area.

4. Confirm whether the RERA registration discloses what is planned for the retained land. Phase 2, commercial development or undisclosed — the RERA disclosure should state the developer’s intention. If the RERA registration is silent on retained land use, the buyer has no contractual basis to object to whatever development the builder later chooses.

5. Have a property lawyer assess the retained land position and confirm that the building’s UDS, access rights and common area boundaries are correctly carved out. A lawyer can trace the title from the original land acquisition through the development agreement to the individual flat sale deed and confirm that the legal separation between building site and retained land is clean.

What Rights Do Flat Buyers Have Over the Retained Land Adjacent to Their Building?

The following table clarifies what rights flat buyers do and do not have over retained land:

The critical takeaway is that flat buyers have no automatic rights over retained land. Every right must be specifically granted in a document — either the sale deed, the development agreement, the RERA disclosure or a separate easement deed. A buyer who assumes rights exist because the retained land is adjacent to the building will discover, too late, that the builder or a subsequent purchaser of the retained land can develop it in any way BBMP permits.

What Is the Builder’s Disclosure Obligation About Retained Land Under RERA?

RERA requires developers to disclose the details of the land on which the registered project is being developed. However, the disclosure obligation does not automatically extend to adjacent land retained by the developer for future development. The RERA registration captures the project land — the portion on which the building is constructed. Retained land is not part of the registered project unless the developer has chosen to include it in the registration.

However, if the marketing materials represented that the buyer would benefit from certain features on the retained land — a park, a commercial amenity, a road — and those features are not delivered, a RERA misrepresentation complaint may be available. The key is whether the representation was made in the marketing materials or the sale agreement. If the builder’s brochure showed a park on the retained land, and the builder later sells that land for a commercial tower, the buyer may have a RERA complaint for misrepresentation. But if the builder made no representation about the retained land’s use, the buyer has no contractual basis to complain.

Buyers should specifically ask what the retained land is planned for and get the answer in writing before signing. A verbal assurance from a sales representative carries no legal weight. The written confirmation should be in the sale agreement or an annexure to it, or in the RERA disclosure if the builder updates the registration.

Frequently Asked Questions

Q1. What does it mean when my apartment building is on only part of a larger land parcel?

It means the developer acquired a larger parcel than the building occupies and has retained the balance for future use. Your flat’s UDS is calculated only on the building site portion, not the whole parcel. The retained land may be developed for Phase 2, commercial use or sold to a third party. You have no automatic rights over the retained land unless specifically granted in your sale deed or a separate easement document. This is a common development model in Bangalore but requires specific verification before purchase.

Q2. Does my UDS cover the whole land parcel or just the building’s portion?

Your UDS covers only the building’s portion of the land parcel, not the whole parcel. The UDS is calculated based on the land area on which the building is constructed, as stated in the building plan sanction and the RERA registration. If the developer acquired ten acres but built the apartment on two acres, your UDS is a share of those two acres only. The remaining eight acres are the developer’s retained land, and you have no ownership share in it unless the sale deed specifically states otherwise.

Q3. Can the builder develop the retained land for commercial use after selling my flat?

Yes, unless the sale deed or RERA disclosure specifically restricts the retained land’s use to residential or limits the type of development. The builder retains full ownership and development rights over the balance land. If the retained land is zoned for commercial use under the master plan, the builder can construct commercial buildings on it. This is why buyers must check the master plan zoning for the retained land before purchase and confirm any representations about its future use in writing.

Q4. Do I have any rights over the retained land adjacent to my building?

You have no automatic rights over retained land. Any right — access, drainage, light or ventilation — must be specifically granted in a formal document. The most common way to establish these rights is through an easement grant in the sale deed or a separate easement deed registered alongside the sale deed. Without a formal easement, the retained land owner can develop the land in any way permitted by BBMP, potentially blocking access, drainage or light to your building.

Q5. How do I find out what the builder plans to do with the retained land?

Check the RERA registration disclosure for any statement about retained land use. Ask the builder directly and request the answer in writing — ideally as an annexure to the sale agreement. Check the BBMP master plan for the zoning of the retained land portion. If the builder will not commit in writing, this is a red flag. A property lawyer can also conduct a title search on the retained land to see if the builder has already entered into a development agreement or sale agreement with a third party for the balance land.

Q6. Can the builder sell the retained land to a third party?

Yes, unless the sale deed with Phase 1 buyers contains a restriction on sale. The builder owns the retained land and can sell it, mortgage it or develop it independently. If the builder sells the retained land to a third-party developer, that developer is not bound by any representations the original builder made to Phase 1 buyers unless those representations were recorded in a document that runs with the land. This is why written confirmation of retained land use is critical before purchase.

Q7. What if the builder mortgaged the whole parcel including the building site?

This is a very high-risk scenario. If the builder mortgaged the entire land parcel before carving out the building site, the bank’s charge may extend to the building site even if the individual flats are not separately mortgaged. The buyer must obtain an EC for the entire land parcel, not just the building portion, to confirm whether a mortgage exists on the whole parcel. If a whole-parcel mortgage exists, the buyer should require the builder to obtain a no-objection certificate from the mortgagee or to discharge the mortgage over the building site before registration.

Q8. What access rights over the retained land must be specifically confirmed?

The following access rights must be specifically confirmed and formally granted: vehicular access from the public road to the building through retained land, pedestrian access for residents and emergency services, drainage and sewer lines passing through retained land, utility lines including electricity, water and gas, and any shared parking or open area that the building’s residents are expected to use. Each of these should be covered by a specific easement grant in the sale deed or a separate registered easement deed.

Q9. Does RERA require builders to disclose plans for retained land?

RERA requires disclosure of the land on which the registered project is developed. Retained land is not part of the registered project unless the developer chooses to include it. However, if marketing materials made representations about retained land features, RERA’s misrepresentation provisions may apply. Buyers should not rely on RERA alone for retained land disclosure. They should specifically ask the builder, get the answer in writing, and have a lawyer verify the retained land’s status independently.

Q10. How does Legal Brigade check retained land risks during property verification?

Legal Brigade’s retained land verification includes: obtaining the RERA registration and confirming the building site area versus the total parcel, obtaining the BBMP building plan sanction and comparing it to the developer’s land holding, obtaining an EC for the entire parcel to check for whole-parcel mortgages, checking the master plan zoning for the retained land, confirming all easements for access and drainage are formally granted, and assessing whether the retained land has already been sold or mortgaged to a third party. This six-step verification is included in Legal Brigade’s standard flat verification service.
