Download the Delhi Apartment Ownership Act, 1986 | Delhi Apartment Ownership Rules, 1987 | The Model-Bye Laws for Delhi Apartment Owners Association

Introduction

Delhi is one of India’s most densely populated cities. Millions of people live in multi-storeyed apartments. Yet, many flat owners do not know the statute that protects their rights. The Delhi Apartment Ownership Act, 1986 is that statute. It is a central legislation enacted by Parliament. It applies specifically to the Union Territory of Delhi. The apartment condominiums in Delhi are governed by the Delhi Apartment Ownership Act, 1986, Delhi Apartment Ownership Rules, 1987 an the Model-Bye Laws for Delhi Apartment Owners Association

This article is an introductory legal guide to the 1986 Act only. It is written for flat owners, buyers, housing societies, and lawyers. I have tried to explain the law in simple language. I have used judicial interpretations wherever relevant. As a property and property related issues lawyer and advocate with more than decade of experience, I thought to put my experience with the Apartment Law in Delhi on my blog.

1. What Is the Act?

The Delhi Apartment Ownership Act, 1986 is a statute governing ownership of apartments in multi-storeyed buildings in Delhi. It recognises each apartment as separate immovable property together with an undivided share in common areas and facilities and regulates the formation of Apartment Owners Associations.

The Delhi Apartment Ownership Act, 1986 (Act No. 58 of 1986) was passed by Parliament. It received assent on 23rd December 1986. The Act came into force by notification of the Administrator of Delhi.

The preamble of the Act is significant. It states that it is the law to provide for the ownership of an individual apartment in a multi-storeyed building and of an undivided interest in the common areas and facilities appurtenant to such apartment and to make such apartment and interest heritable and transferable and for matters connected therewith or incidental thereto.

The Act has six Chapters and twenty-seven sections. Its primary purpose is to confer heritable and transferable ownership rights on apartment owners. It also creates a legal framework for managing common areas and facilities.

Before this Act, flat owners in Delhi had no specific statutory protection. They depended on general property law and builder undertakings. The Act changed that fundamentally.

2. Scope and Applicability

Section 2 defines the scope of the Act. The Act applies to every apartment in a multi-storeyed building in Delhi. However, the building must satisfy certain conditions.

Conditions for Application

• First, the building must be constructed mainly for residential or commercial purposes.
• Second, the building must be on freehold land or leasehold land. If leasehold, the lease must be for 30 years or more.
• Third, the construction must be by a group housing cooperative society or any person or authority.

The Act applies to buildings constructed both before and after its commencement. This is a critical provision. Existing flat owners also got protection under this statute i.e. flats constructed before Dec 1986.

What Is a Multi-Storeyed Building?

A multi-storeyed building means a building with four or more apartments. It can also mean two or more buildings in a block, each having two or more apartments, with a total of four or more. Buildings with only two or three apartments can opt into the Act by declaration.

This definition is important in litigation. Courts have had to determine whether a complex qualifies. The definition also covers commercial and mixed-use buildings.

3. Key Definitions of Terms

Section 3 of the Act contains twenty-four definitions. These are the building blocks of the entire legislation. Every dispute and every right traces back to these definitions.

Apartment

An apartment means a part of any property for any type of independent use. It includes one or more rooms on one or more floors. Most importantly the apartment must have direct access to a public road or to a common area leading to such a road. It also includes a garage or domestic aide room provided by the promoter. Some important definitions worth referring are:

Apartment Owner

An apartment owner is the person owning an apartment and an undivided interest in common areas. The percentage of undivided interest is specified in the Deed of Apartment. A lessee with a lease of 30 years or more is also included.

Common Areas and Facilities

This is one of the most litigated definitions. Common areas include the land, foundations, columns, roofs, corridors, stairs, basements, yards, gardens, parking areas, and shopping centres. It also includes central services like power, gas, water, and elevators.

Courts have consistently held that parking areas are part of common areas. Promoters cannot sell parking spaces separately if they fall within this definition. This was confirmed in several High Court judgments.

Common Expenses and Profits

Common expenses are all sums assessed by the Association of Apartment Owners for maintenance, repair, or replacement of common areas in the condominium. Whereas, common profits are the balance of income from common areas after deducting common expenses.

Promoter

A promoter is the authority, person, or cooperative society that constructs the multi-storeyed building. The promoter has specific obligations under the Act. These obligations are enforceable in courts. As per this definition any central government department building apartment complex in Delhi for its staff falls under the ambit of this law.

The definitions in Section 3 are the first point of reference in any apartment dispute in Delhi. Every lawyer advising on Delhi apartment law must study these carefully.

For a comparative analysis of these definitions with the UP Apartment Act, read: Reimagining Urban Living: Understanding the UP Apartment Act, 2010.

4. Ownership of Apartment

4.1 Exclusive Ownership Rights

Section 4 Chapter II is the heart of the Act. It confers exclusive ownership and possession of an apartment on every allottee. This right arises from the date of allotment or transfer by the promoter.

Every apartment owner is also entitled to an undivided interest in common areas. This interest is computed on the basis of the apartment’s value relative to the property’s total value. This percentage is stated in the Deed of Apartment.

Here, I must submit that the law is little outdated as the law does not contemplate the publication of a deed of declaration declaring the share of common areas and facilities, voting share, share in land etc. of each apartment in a single document. This is in contrast to the provision of Deed of Declaration under the UP Apartment Act.

Permanence of Undivided Interest

Section 4(4) declares that the percentage of undivided interest has a permanent character. It cannot be altered without written consent of all apartment owners. This is a strong protection against arbitrary changes by promoters or authorities.

Further, the undivided interest in common areas cannot be separated from the apartment. It is automatically conveyed with the apartment. Even if it is not expressly mentioned in the conveyance deed, it passes along.

No Partition of Common Areas

Section 4(5) is a crucial provision. No apartment owner or any other person can bring an action for partition of common areas. Any covenant to the contrary is void. This prevents builders from slicing up common areas after handover.

It must be noted that provisions of section 4 restrain the developers from adding more apartments after sale of even a single unit in original number of flats sanctioned by map sanctioning authority viz. DDA or MCD.

4.2 Transferability and Heritability

Section 5 declares each apartment to be heritable and transferable immovable property. An apartment owner can sell, mortgage, lease, gift, or exchange the apartment. All laws applicable to immovable property apply equally.

This provision gave apartment ownership a solid legal footing. Before this, there was uncertainty about whether a flat constituted immovable property. Section 5 removed all ambiguity.

Exception: Cooperative Housing Societies

There is a proviso to Section 5. Where an apartment is allotted by a group housing cooperative society, the transferability is regulated by the law applicable to that society. This is important for DDA and cooperative society flat owners.

4.3 Prohibited Works

Section 11 prohibits any work that is prejudicial to the soundness or safety of the property. No apartment owner can reduce the value of the property. No one can impair any easement or hereditament.

Critically, no apartment owner can add any material structure or excavate any basement without the written consent of all other apartment owners. This is a unanimous consent requirement. Courts have strictly enforced this.

In the case of Sugar Apartments Flat Owners Society v. Sequoia Construction Pvt. Ltd., the Delhi High Court examined claims under the Act for unauthorized construction. The Court held that the statutory obligations of the promoter are enforceable by apartment owners.

In the Sagar Apartments Residents vs Sequoia Construction (P) Ltd. the Court held that Sequoia Construction had no right to raise additional floors or structures after handing over the flats, and that several facilities – including the swimming pool, changing rooms, gardens, pathways, and other areas listed in the agreement’s schedules – constitute common areas belonging to the apartment owners. It partly decreed the suit by affirming owners’ easementary rights over these common areas while declining reliefs that lacked evidentiary support, such as demolition orders and accounting claims.

4.4 Encumbrances

Section 12 allows apartment owners to mortgage or create charges against their apartments. However, an encumbrance can only be created against the owner’s apartment. It cannot affect the apartments of other owners.

If a charge or encumbrance affects two or more apartments, each owner can discharge their proportionate share to get a release. This protects individual apartment owners from common charges created by others.

5. The Deed of Apartment

5.1 Contents of the Deed of Apartment

The Deed of Apartment is a mandatory instrument under the Act. The promoter must execute this deed within three months of allotment or transfer.

The Deed must contain the following essential particulars.

• First, the name of the allottee.
• Second, a description of the land and multi-storeyed building.
• Third, floor plans certified by an architect.
• Fourth, the apartment number, area, and access to common areas.
• Fifth, a description of common areas and the percentage of undivided interest.
• Sixth, the value of property and each apartment.
• Seventh, a statement that the apartment is free from encumbrances. Eighth, the purpose for which the building and each apartment is restricted.

Competent Authority

The Act designates specific competent authorities. These include a Secretary in the Delhi Administration, the Vice-Chairman of the Delhi Development Authority (DDA), and the Land and Development Officer. These officers handle registration, succession, and disputes under the Act. Currently land ownership wise competent authorities have been appointed:

For apartments constructed on DDA land:

Competent Authority is Vice Chairman, Delhi Development Authority (DDA), Office Address: Vikas Sadan, INA, New Delhi – 110023

Role under the Act

• Registration and supervision of Deed of Apartment matters
• Recognition of Apartment Owners Associations (AOA)
• Administrative decisions relating to apartment ownership disputes

For apartments constructed on Central Government land)

Competent Authority is Land & Development Officer (L&DO), Office Address: Land & Development Office, Nirman Bhawan, New Delhi – 110108

Role under the Act

• Administration of apartment ownership matters relating to Central Government leasehold land
• Registration or endorsement of apartment ownership instruments where applicable

Succession

Section 13(4) deals with succession. If an apartment passes by inheritance, the successor must apply to the competent authority within six months. The competent authority has civil court powers to decide succession disputes. Its decision is treated as a decree.

5.2 Registration of the Apartment Deed

Section 14 makes the Deed of Apartment compulsorily registrable under the Registration Act, 1908. Every endorsement relating to a transfer must also be registered. This creates a public record of all apartment transactions.

Section 14(4) is important. Once the Deed is registered, every person acquiring the apartment is deemed to have notice of its contents. Ignorance of registered contents is not a defence.

6. Association of Apartment Owners

6.1 Formation of the Association

Chapter IV Section 15 mandates the formation of an Association of Apartment Owners (AOA). The AOA is responsible for the administration of the apartments and their appurtenant property. It manages common areas and facilities by imposing common expenses. .

Where multiple multi-storeyed buildings exist in a designated block or pocket, there shall be only one AOA for the entire area. This promotes unified governance.

You can read my other article on: Formation and Registration of an Apartment Owners Association in Delhi: A Complete Legal Guide (2025)

You can also read the article: All about Election of Apartment Owners Association or How to form an Association of Apartment Owners under UP Apartment law to get an idea about AOA election in Uttar Pradesh i as the provisions of the law of both states are almost similar.

6.2 Model Bye-Laws

The Administrator of Delhi is empowered to frame model bye-laws. Every AOA must adopt bye-laws at its first meeting in accordance with these model bye-laws. Any departure from model bye-laws requires prior approval of the Administrator.

The Government has issued a Model Bye-law for all the apartment owners association in Delhi which is mandatorily required to be adopted, enforced and followed.

The model bye-laws addresses specific matters. These include election of a Board of Management, appointment of a President, Secretary, and Treasurer, method of meetings and quorum, maintenance of common areas, and collection of common expenses.

Board of Management

The Board of Management is the governing body of the AOA. It is elected from among apartment owners. One-third of the Board members must retire annually. The Board can also appoint a Manager and delegate powers to the Manager.

6.3 Insurance

Section 16 empowers the Board or Manager to obtain insurance for the property. Insurance must be obtained if required by the bye-laws or by a majority of apartment owners. It can also be demanded by a first mortgagee. Insurance premiums are treated as common expenses.

6.4 Disposition on Destruction

What happens if the building is destroyed? Section 17 provides the answer. If the AOA does not decide to repair or rebuild within sixty days, the property is deemed to be owned in common by all apartment owners. Their share is proportionate to their undivided interest in common areas.

After that, any apartment owner can bring a suit for partition. The net sale proceeds and insurance money are distributed proportionately. This is a thoughtful provision that protects owners even in catastrophic events.

Important: Every AOA in Delhi must have properly framed bye-laws. Operating without registered bye-laws can expose the AOA to legal challenges on every decision.

7. Common Expenses and Profits

7.1 Distribution of Common Profits

Section 19 establishes a clear principle. Common profits are distributed among apartment owners in proportion to their undivided interest. Similarly, common expenses are charged in the same proportion.

This proportionality principle is fundamental. It prevents any one apartment owner from bearing a disproportionate burden. It also prevents any one owner from claiming a larger share of profits.

7.2 No Waiver of Contribution

Section 20 is a non-obstante provision. An apartment owner cannot escape liability for common expenses by claiming non-use of common areas. Even if you abandon your apartment, you still owe your share of common expenses. This prevents free-riding.

7.3 Common Expenses as a Charge

Section 21 gives the AOA a powerful recovery tool. All unpaid common expenses assessed by the AOA constitute a charge on the apartment. This charge has priority over all other charges except government and municipal taxes, and the first mortgage.

This means an AOA can enforce recovery of maintenance dues against the apartment itself. This is significantly stronger than a mere personal claim against the owner.

7.4 Liability on Transfer

Section 23 protects the AOA against transfer-related defaults. When an apartment is sold or transferred, the buyer and seller are jointly and severally liable for all unpaid common expenses at the time of transfer.

The buyer can demand a statement of unpaid dues from the Board before purchasing. The buyer is not liable for amounts exceeding what is shown in that statement. This protects buyers from hidden liabilities.

8. Important Case Laws

8.1 O.S. Bajpai v. The Administrator

The Delhi High Court in O.S. Bajpai v. The Administrator examined the persistent non‑implementation of the Delhi Apartment Ownership Act, 1986, highlighting how builders routinely violate statutory requirements – such as executing deeds of apartment, conveying undivided interest in common areas, and facilitating the formation of apartment owners’ associations – while authorities claimed helplessness due to the Act’s lack of penal provisions. The Court noted that both the Union Government and the Delhi Government had long acknowledged these structural defects and had even drafted a new bill, but no legislative progress had occurred, reflecting administrative apathy despite the Act’s clear purpose of protecting apartment owners’ rights.

While the Court could not compel Parliament to enact new legislation, it strongly urged the authorities to revive and process the pending Cabinet Note for a fresh bill. Simultaneously, it issued detailed directions to ensure meaningful enforcement of the existing Act—such as appointing competent authorities, mandating execution and registration of deeds of apartment, ensuring formation of owners’ associations, and transferring building management from builders to these associations—so that apartment owners could actually enjoy the rights the statute intended to confer.

8.2 Sugar Apartments Flat Owners Society v. Sequoia Construction Pvt. Ltd.

This is one of the earliest reported cases under the Act. The Delhi High Court interpreted Section 2 (application), Section 13 (deed of apartment), and Section 15 (AOA bye-laws). The Court upheld the plaintiffs’ rights and granted interim relief. It held that denial of relief encourages breach of statutory obligations on the promoter.

8.3 Core Principles

Multiple High Court decisions across India have laid down consistent principles for apartment ownership statutes. These principles apply equally to the Delhi Act.

• First, a promoter cannot change building plans without the consent of intending purchasers.
• Second, common areas cannot be sold by the promoter once the AOA is formed.
• Third, parking areas as defined in Section 3(j)(iii) are part of common areas. Promoters cannot charge separately for them.
• Fourth, the obligation to execute the Deed of Apartment is mandatory. The promoter cannot evade this duty.
• Fifth, the AOA can bring suits on behalf of apartment owners for matters relating to common areas.

8.4 Supreme Court Influence

In DLF Qutab Enclave Complex v, State of Haryana case, the Supreme Court considered community buildings under Delhi law. The Court held that community buildings covered under relevant state laws could be transferred by the colonizer under a development licence. However, this does not override the Delhi Apartment Ownership Act for privately built group housing.

The Supertech Ltd. v. Emerald Court Owner Resident Welfare Association is another landmark. The Supreme Court held that any change in a sanctioned plan or common area allocation without owner consent is illegal. This principle is directly applicable in Delhi.

9. Apartment Act vs RERA

The Real Estate (Regulation and Development) Act, 2016 (RERA) is a central legislation. It applies to all real estate projects across India, including Delhi. Many flat buyers are confused about the relationship between RERA and the Delhi Apartment Ownership Act.

9.1 Key Differences

RERA primarily governs project registration, promoter obligations, and consumer protection in real estate. The Delhi Apartment Ownership Act governs ownership structure, common area rights, and AOA governance. Both laws operate simultaneously. They complement each other.

RERA requires registration of projects above a threshold. It mandates a separate escrow account for buyers’ funds. It provides a grievance redressal forum in the form of the Real Estate Regulatory Authority.

The Delhi Act, on the other hand, focuses on post-delivery rights. It gives rights once you own the apartment. This law protects your interest in common areas for which you pay maintenance. The Act crucially structures the governance of your housing society.

9.2 When to Use Which Law

If the promoter has not delivered your flat on time, use RERA. Whereas post delivery if the promoter has not executed the Deed of Apartment, use the Delhi Act. If the promoter has illegally sold common areas, use both laws depending on the forum and relief sought. If the AOA is not being formed, use the Apartment Act.

10. Practical Importance for Delhi Flat Owners

10.1 Checklist Before Buying a Flat in Delhi

• Verify that the building qualifies under the Delhi Apartment Ownership Act.
• Demand a copy of the registered Deed of Apartment from the promoter.
• Check the percentage of undivided interest in common areas in the Deed.
• Confirm that parking areas are classified as common areas.
• Obtain a statement of outstanding common expenses from the AOA.
• Verify that the AOA is properly formed and has registered bye-laws.
• Check whether there are any prohibited works or encumbrances on the apartment.

10.2 Checklist After Taking Possession

• Become an active member of the AOA.
• Attend general body meetings and vote on resolutions.
• Pay common expenses on time to avoid a charge on your apartment.
• Do not carry out any structural work without the consent of all apartment owners.
• Insist that the Board obtains adequate insurance for the property.
• If common areas are being encroached upon, invoke Section 4(5) and Section 7.

10.3 When to Consult a Lawyer

You should consult a lawyer if the promoter has not executed the Deed of Apartment. You should also do so if the AOA is not being formed. Seek legal advice if common areas are being encroached upon or sold. Get legal help if you are being denied access to maintenance records.

A lawyer specialising in apartment law can also help in AOA election disputes, recovery of common expenses, and challenging illegal constructions under Section 11.

11. Conclusion

The Delhi Apartment Ownership Act, 1986 is the foundational statute for apartment living in Delhi. The statute defines who owns what. It further protects common areas. It also creates a mandatory governance structure through the AOA. Most importantly the Act links the apartment with the land beneath it.

The Act has only twenty-seven sections. But those sections cover a wide range of rights and obligations. Every flat owner in Delhi should know this statute. Every buyer should verify compliance before signing a sale deed.

Courts have consistently upheld the rights conferred by this Act. Promoters who violate its provisions face civil liability. The Act also works in tandem with RERA to give flat buyers comprehensive protection.

As a practising Supreme Court lawyer with extensive experience in apartment law, I have observed that most disputes arise from ignorance of this statute. Informed apartment owners protect themselves better. They make better decisions in AOA meetings. They take timely legal action when needed.

12. Frequently Asked Questions (FAQs)

Q1. Does the Delhi Apartment Ownership Act, 1986 apply to commercial flats?

Yes. The Act applies to apartments used for residential or commercial purposes. An apartment is defined broadly to include use for offices, trade, or business.

Q2. Can the promoter sell parking spaces separately in Delhi?

No. Parking areas are defined as part of common areas under Section 3(j)(iii). The promoter cannot sell them separately. Courts have repeatedly held that such sales are void.

Q3. What happens if the promoter does not execute the Deed of Apartment?

The promoter is in violation of Section 13. Apartment owners can approach the competent authority. They can also file a civil suit for execution of the deed. A complaint under RERA is also available if the project is registered.

Q4. Can I be made liable for my neighbour’s unpaid maintenance?

Only in limited circumstances. Section 12 protects you from charges created by another owner’s contractor. However, Section 23 makes you jointly liable for the seller’s arrears when you buy a flat. Always get a dues clearance certificate before buying.

Q5. Is the Delhi Apartment Ownership Act different from the DDA Act?

Yes. The DDA Act governs land development and planning in Delhi. The Delhi Apartment Ownership Act governs ownership rights and management of apartments. Both can apply to DDA flats, depending on the circumstances.

Q6. Can a tenant vote in AOA elections?

Tenants are not apartment owners. Only apartment owners can vote in AOA elections. However, the bye-laws may provide for associate membership to tenants. You should check the specific bye-laws of your AOA.

Q7. Is the Delhi Apartment Ownership Act applicable to builder floors in Delhi?

Yes, if the building qualifies as a multi-storeyed building under the Act. A building with four or more apartments normally falls within the statutory definition. Builder floor developments that meet this threshold may therefore be governed by the Delhi Apartment Ownership Act, 1986.

Q8. What is the difference between a Deed of Apartment and a Sale Deed?

A Sale Deed transfers ownership of the residential house which is not an apartment. A Deed of Apartment, on the other hand, is a statutory sale deed document under the 1986 Act that records the apartment owner’s undivided share in the common areas and facilities of the property along with other mandatory disclosures.

Q9. Can a builder add additional floors after selling apartments?

Generally no. Once apartments are sold, the promoter cannot alter sanctioned building plans or construct additional floors without the consent of the apartment owners. Courts have repeatedly held that such alterations violate the rights of apartment owners under apartment ownership laws.

Q10. Who regulates disputes between apartment owners and the Association of Apartment Owners?

Disputes may be addressed through civil courts, the competent authority under the Act, or other statutory forums depending on the nature of the dispute. In many cases involving maintenance dues, governance issues, or common area rights, civil courts exercise jurisdiction.

Q11. Is the Deed of Apartment mandatory under the Delhi Apartment Ownership Act, 1986?

Yes. The Deed of Apartment is a mandatory statutory instrument under Section 13 of the Delhi Apartment Ownership Act, 1986. The promoter must execute the deed within three months of allotment or transfer of the apartment. The deed records the apartment owner’s undivided share in common areas and facilities, and it must be registered under the Registration Act, 1908. Failure to execute this deed can give apartment owners the right to initiate legal proceedings against the promoter.

Q12. Can common areas in an apartment building be sold by the builder?

No. Common areas and facilities belong collectively to all apartment owners. These include land, foundations, roofs, staircases, corridors, lifts, parking areas, and other shared facilities. Once apartments are sold, the promoter cannot sell or transfer common areas separately. Courts have repeatedly held that such attempts are illegal and void.

Q13. Can an apartment owner make structural changes inside their flat?

Only limited internal alterations are permitted. Section 11 of the Delhi Apartment Ownership Act prohibits any structural changes that affect the safety, stability, or value of the building. No apartment owner can construct additional structures, excavate basements, or modify structural elements without the written consent of all other apartment owners.

Q14. What happens if an apartment owner does not pay maintenance charges?

Maintenance charges assessed by the Association of Apartment Owners are classified as common expenses. Under Section 21 of the Act, unpaid common expenses become a charge on the apartment itself. The Association can recover the dues through legal proceedings, and the charge may take priority over most private claims except government taxes and the first mortgage.

Q15. Can a builder change the sanctioned building plan after selling apartments?

No. Once apartments are sold, the promoter cannot change the sanctioned building plan or construct additional floors without the consent of the apartment owners. Courts in multiple cases have held that such changes violate the statutory rights of apartment owners and the doctrine of legitimate expectation.
