Asked by a reader in Bengaluru

The apartment association wants to convert a common area to commercial use. Can they?

A majority vote does not automatically authorise converting common space into a commercial unit. For property under the Karnataka Apartment Ownership Act, common areas must be used consistently with their intended purpose, and changing owners' undivided percentages requires everyone's consent through a registered amended declaration. Some authorised arrangements for leasing retained areas are different. Read the declaration, sanctioned plan and bye-laws together before deciding what the association can approve. Request the proposed resolution and drawings before work or a lease begins.

There are three locks on this door, they are held by three different people, and an association that opens one has opened none of the others.

Section 3(f), Karnataka Apartment Ownership Act, 1972. Unless otherwise provided in the Declaration, common areas and facilities include the land on which the building stands, the structural elements, halls, corridors, lobbies, stairs and fire escapes, the basements, cellars, yards, gardens, parking areas and storage spaces, the premises for staff, the central installations, the lifts, tanks, pumps and common apparatus, such community and commercial facilities as may be provided for in the Declaration, and all other parts necessary or convenient to the property's existence, maintenance and safety or normally in common use.

That last item is worth reading twice. Commercial facilities can be common areas, but only where the Declaration provided for them. A facility the Declaration described as a community hall does not become a commercial facility because a general body voted to let it out.

The first lock: the Declaration and the 1972 Act

Section 6(2) is the provision that decides most of these disputes. The percentage of the undivided interest of each apartment owner in the common areas as expressed in the Declaration shall have permanent character, and shall not be altered without the consent of all of the apartment owners expressed in an amended Declaration duly executed and registered. The undivided interest cannot be separated from the apartment and is deemed conveyed with it even if the conveyance does not mention it.

Section 6(3) then says the common areas and facilities shall remain undivided, that no apartment owner or any other person shall bring any action for partition or division of any part of them unless the property is removed from the Act, and that any covenant to the contrary shall be null and void. Section 6(4) confines each owner to using the common areas in accordance with the purpose for which they are intended, without hindering or encroaching on the rights of others. Section 8 prohibits any owner from adding any material structure or excavating without the unanimous consent of all the other owners. And Section 14 requires all the apartment owners to act together to remove the property from the Act at all.

The word running through every one of those provisions is all, not a majority. Section 3(n) does define a majority as owners holding fifty one per cent or more of the votes, but that definition governs the matters the Act and the bye-laws leave to a majority. Altering the character or the shares in the common areas is not one of them.

The second lock: the plan and the bye-laws

A resolution cannot change what the building is sanctioned for. Section 239 of the Bruhat Bengaluru Mahanagara Palike Act, 2020 says no person shall construct any building or structure of a permanent nature, or execute work relating to the construction of a building including an addition, alteration or modification of an existing one, except in accordance with the building bye-laws and on the sanction of the corporation. Section 240 sets out how that sanction is obtained. Section 144(6) charges double property tax on a building constructed in violation of the bye-laws, and its proviso says the levy confers no right to regularise the violation and no title or legal status. So an unauthorised commercial conversion produces a permanent tax penalty and a permanent exposure.

The third lock: the land may not be the association's at all

In an approved layout, Section 17(2A) of the Karnataka Town and Country Planning Act, 1961 requires the owner to relinquish the roads and parks to the local authority and the civic amenity areas to the planning authority by registered deed, free of cost. Where the space the association has in mind is a relinquished civic amenity area, it does not belong to the owners collectively and no vote of theirs is relevant to it. That is the point at which several of these proposals quietly collapse once the layout file is read.

What can lawfully be done

  • Read the registered Declaration, if one exists, and the statement under Section 11(1)(g) of the purposes for which the building and the apartments are intended and restricted as to use
  • Read Section 11(1)(k), which records the method by which the Declaration may be amended, consistently with the Act
  • Check whether the space is described in the Declaration as a community or commercial facility under Section 3(f)(7), or as a limited common area under Section 3(m)
  • Check the sanctioned plan for the use to which that area is put and whether the zoning permits a commercial activity
  • Check whether the space is a relinquished civic amenity area, in which case the planning authority owns it
  • Keep any income in the common fund, since Section 10 requires common profits to be distributed according to the undivided interest and not applied at the committee's discretion
  • Where the promoter is still in the picture, note that Section 14(2)(ii) of the 2016 Act bars him from altering the common areas without the written consent of at least two thirds of the allottees

Many Bengaluru buildings were never submitted to the 1972 Act at all, because no Declaration was executed and registered, and the association exists as a registered society instead. That does not improve the position. A society acts within its registered objects and bye-laws, and it still does not own the common areas, because each owner's undivided share came with his own conveyance. An owner who objects has a civil remedy, and the practical first step is an injunction restraining the work before it starts rather than a suit for restoration after it is done, which is why our note on temporary injunctions is the one to read early. The broader question of what an association may and may not charge is dealt with in the apartment association answer.

Our apartment association is charging arbitrary maintenance and cutting off services. What are our rights?

Start with the association's legal structure, registered declaration and bye-laws. Under the Karnataka Apartment Ownership Act, common expenses and their allocation follow the statutory framework, and the bye-laws govern management and collection. Ask for the resolution, budget and calculation supporting the demand. If essential services are threatened, seek urgent advice about an injunction while separately addressing the amount genuinely due. Do not assume every Bengaluru association is governed by the same Act or that a disputed charge can simply be ignored.

Property & Real Estate

The builder is charging separately for the car park. Is that allowed?

Ask whether the builder is selling an enclosed garage or allocating a space in common parking. RERA defines a garage by its roof and walls on three sides, and treats open parking as common area. Those categories should not be blurred by calling every marked bay a garage. Check the sanctioned plan, project disclosures and agreement before accepting a separate charge. A right to use a parking space is different from ownership of a separately saleable garage.

Property & Real Estate

Our project never received an occupancy certificate. What are our rights?

For a covered project, the promoter must obtain the completion or occupancy certificate required by the applicable law and make it available to allottees or their association. Ask for the certificate itself and check which building or phase it covers. If it is missing, obtain the authority's recorded position and identify the reason. A RERA complaint can seek compliance. Keep the sanctioned plans and handover documents ready. Paying tax or moving into the flat does not prove that the required certificate exists.

Property & Real Estate

My siblings will not divide our family property. How does a partition work?

Begin with the title documents and a family tree to identify who actually owns a share. If everyone agrees, record a properly drafted settlement or partition and complete the registration required for the document. If agreement fails, a partition suit can determine the shares and arrange division. A preliminary decree declaring shares is different from the final division. Include all necessary owners and properties, and identify any disputed sale or mortgage before assuming that the family can simply split the land equally.

Property & Real Estate

The sub-registrar refused to register my sale deed because there is no e-khata. What do I do?

Ask for a written refusal and the precise document the registrar says is missing. Section 71 of the Registration Act generally requires recorded reasons for refusing registration. A refusal on grounds other than denial of execution can be appealed to the Registrar within thirty days. Meanwhile, check the final eKhata process and your property's record with the responsible municipal office. An oral statement at the counter is not enough to assess the legal position or protect an appeal deadline.

Property & Real Estate

The builder has handed over the flat but not the khata. What can I do?

Ask the builder to identify what prevents the khata from being issued and provide the missing documents. In a covered RERA project, the promoter has duties concerning the completion or occupancy certificate, conveyance and handover of documents. A complaint can seek compliance with those duties. Keep the agreement, handover record and unanswered requests together. Also check the municipal application itself, because a processing problem and a missing project approval need different action. Possession alone does not complete every obligation.
