Can a Builder Sell Terrace Rights in Bangalore, Karnataka?

Under Karnataka real estate law, a builder cannot unilaterally sell or retain rights to a common terrace. Rooftops are statutory common areas that belong collectively to all apartment owners through the association.

What Karnataka Law Says About Terrace Ownership

In Karnataka, a promoter or builder has no legal authority to sell, lease, or retain exclusive rights over the common terrace of a residential building. Under Section 2(n) of the Real Estate (Regulation and Development) Act, 2016 (RERA), common areas specifically include roofs, staircases, and open spaces intended for collective use. Furthermore, Section 17 of RERA mandates that the promoter must execute a registered conveyance deed transferring ownership of all common areas to the association of allottees within the prescribed timeframe.

The Karnataka Apartment Ownership Act, 1972 (KAOA) reinforces this principle. Under Section 3(f) of the Act, roofs, halls, corridors, and basements are classified as 'common areas and facilities'. Section 6 of the KAOA stipulates that each apartment owner is entitled to an undivided interest in the common areas, and these areas shall remain undivided, prohibiting any covenant or partition to the contrary. An exception applies only where an open terrace is structurally attached directly to a specific unit and sanctioned by the Bruhat Bengaluru Mahanagara Palike (BBMP) as an exclusive private terrace appurtenant to that apartment. A general building terrace cannot be monetized or sold separately.

Builder Tactics and Court Rulings Against Terrace Sales

Developers in Bangalore frequently introduce one-sided clauses into standard builder-buyer agreements, asserting that the terrace remains their private property, reserving future construction rights, or selling rooftop access to top-floor owners for an extra fee. Many builders also attempt to retain terraces to install mobile transmission towers or commercial billboards to pocket monthly rentals.

The judiciary has consistently rejected these practices. The Supreme Court of India in landmark precedents, including *Nahalchand Laloochand Pvt. Ltd. v. Panchali Co-operative Housing Society Ltd.*, established that common facilities cannot be treated as independent saleable units by developers. The Karnataka High Court has held that an agreement between a land owner or builder purporting to convert a common terrace into a private asset is contrary to law and unenforceable. A contract clause cannot override statutory obligations created by RERA and state apartment statutes.

Legal Remedies and Taking Action in Bangalore

If a developer or top-floor purchaser attempts to restrict common access or erect unauthorized structures on the terrace, the apartment owners have enforceable legal remedies. An aggrieved association can immediately approach the Karnataka Real Estate Regulatory Authority (K-RERA) under Section 31 of RERA to challenge illegal common-area alienation, seek removal of encroachments, and compel formal handover of the terrace. Alternatively, an association can initiate proceedings before the jurisdictional civil court or consumer disputes redressal commission.

Steps

• Obtain and verify the BBMP-sanctioned building plan and Karnataka RERA disclosures to confirm the terrace is formally designated as a common area.
• Review your Sale Deed and the Deed of Declaration under the Karnataka Apartment Ownership Act to check undivided share (UDS) calculations and common area definitions.
• Convene an extraordinary general meeting of your Apartment Owners Association (AOA/RWA) to pass a formal resolution protesting the unauthorized sale or obstruction.
• Serve a comprehensive legal notice upon the builder and unauthorized occupant demanding immediate restoration of free terrace access.
• File a formal complaint before Karnataka RERA (K-RERA) or the jurisdictional civil court seeking an injunction against construction or commercial exploitation of the rooftop.

Common mistakes

• Assuming that a signed builder-buyer clause granting terrace rights to the builder is legally binding despite violating RERA and KAOA.
• Delaying action until a mobile tower, billboard, or permanent penthouse construction has already been completed.
• Engaging in informal verbal discussions with the developer instead of creating a written legal paper trail through the association.
• Attempting to break locks or physically confront private security without a documented police complaint or court order.

Questions people ask

Can a top-floor flat owner lock the apartment terrace in Bangalore?

No. Unless the terrace is an exclusive private balcony attached solely to that apartment in the BBMP-approved plan, a resident cannot lock a common roof or restrict other co-owners from accessing essential facilities like overhead water tanks and solar heaters.

Does signing a contract that gives the builder terrace rights waive our claim?

No. Under Indian contract law and Karnataka property jurisprudence, any clause in an agreement for sale that contradicts statutory protections under RERA or the Karnataka Apartment Ownership Act is considered void and unenforceable.

Who receives the rental income if a mobile tower is placed on the terrace?

Because the terrace is common property owned collectively by all unit owners, any commercial revenue from telecom towers, solar setups, or signage belongs exclusively to the apartment association, not the builder.
