Forming an RWA or AOA and Taking Over From the Builder

Under RERA the builder must enable an association of allottees within three months of a majority of units being booked, then hand over common areas, documents and funds. Where no local law says otherwise, that is within 30 days of the occupancy certificate. The legal form depends on your state: a co-operative society in Maharashtra, an apartment owners' association in Haryana or Karnataka, or a society under the 1860 Act.

Key takeaways

• RERA section 11(4)(e): the promoter must enable an association within three months of a majority of allottees booking, unless local law sets another rule.
• Section 17(2): documents, plans and common areas go to the association within 30 days of the occupancy certificate where no local law applies, with the corpus and maintenance balance.
• Maharashtra's rule 9 makes the promoter apply to register the co-operative within three months of 51% booking; the registration fee is Rs 2,500 and the society needs 10 members or a majority.
• Karnataka's High Court held in 2026 that RERA and the Apartment Ownership Act govern different stages: an owners' association there needs conveyed owners, not just allottees.
• The builder stays liable for structural and workmanship defects for five years from possession under section 14(3).

Which kind of association your building needs

RERA says an association must exist but not what legal form it takes. That comes from state law, and choosing the wrong vehicle can leave you with a body that cannot hold title to common areas.

Haryana: declaration first

An AOA in Haryana only works once the building is under the 1983 Act. For licensed colonies, the owner must execute and register a declaration within 90 days of the part-completion or completion certificate, filed with floor plans certified by an architect, and registered by the sub-registrar together with each deed of apartment. The Town and Country Planning Department examines it. Many Gurgaon complexes run a separate RWA under the 2012 societies law as well. The two laws do not override each other, and membership in each is voluntary, which is why some complexes end up with rival bodies. Our HRERA guide covers the complaint route against the promoter.

Karnataka: allottees vs owners

In Akhilesh Anand v. State of Karnataka, the Karnataka High Court held that a RERA association of allottees and a KAOA association of apartment owners are different bodies: the second can only be formed by registered owners after conveyance and a deed of declaration. In Sobha Ltd v. Deputy Registrar of Co-operative Societies (3 March 2026), the court held that RERA is not repugnant to the KAOA because the two govern different stages of a project. In practice, a Bengaluru complex may need an interim allottees' body during construction and a KAOA association after sale deeds are registered.

Maharashtra: the builder files

Under MahaRERA rule 9, the promoter must apply to the registrar, on the buyers' behalf, within three months of 51% of allottees in a building or wing booking. If the agreement sets no date, conveyance of a single building is due within three months of the earlier of the occupancy certificate or full payment by 51% of allottees. When the builder does not convey, MahaRERA can order it, and the older fallback is deemed conveyance.

What the builder owes you under RERA

• Enable the association within three months of majority booking, where no local law applies (section 11(4)(e)).
• Run the essential services at reasonable charges until the association takes over (section 11(4)(d)).
• Convey your unit to you and the undivided share of common areas to the association (section 11(4)(f)); section 17 fixes three months from the occupancy certificate where local law is silent.
• Hand over physical possession of common areas, plans and documents, within 30 days of the occupancy certificate if local law is silent (section 17(2)), along with the corpus collected from buyers and the balance in the maintenance account.
• Fix defects reported within five years of possession, free, within 30 days, failing which the allottee can claim compensation (section 14(3)).

The handover checklist

Legal and approvals

• Title documents, the mother deed, and the registered conveyance or declaration covering common areas.
• Sanctioned building plans, occupancy and completion certificates.
• Fire NOC, lift licences, the electrical inspector's approval, and Pollution Control Board consent for the STP and DG sets.
• Property-tax records for common areas, paid up to the handover date.

Technical

• As-built drawings for architecture, electrical, plumbing and fire systems. Without them, every future repair starts with guesswork.
• Operation and maintenance manuals, warranty certificates and test reports for lifts, pumps, DG sets, STP and WTP.
• Current AMC contracts, with expiry dates and who pays until they lapse.
• A joint snag audit of common areas, signed by both sides, which starts your section 14(3) clock on each defect.

Money

• The IFMS or maintenance security, with the interest it earned, and a statement by flat. Our IFMS explainer covers what it is.
• The sinking or corpus fund, the maintenance account balance, and audited accounts for the builder's period in charge.
• A list of dues owed by the builder on unsold units, which are the builder's to pay like any owner's.

Worked example: what an IFMS corpus should look like

Gurgaon IFMS is commonly Rs 100 to Rs 200 per sq ft. Take a 300-flat complex at 1,500 sq ft average and the low end, Rs 100:

• Per flat: 1,500 x Rs 100 = Rs 1,50,000.
• Complex: Rs 1,50,000 x 300 = Rs 4.5 crore.
• Interest matters. HRERA Gurugram has ordered a builder to pay 11% a year on IFMS collected from a buyer, holding that it could not keep the interest. At 11%, Rs 4.5 crore is Rs 49.5 lakh a year. Even at half that rate, a few years of interest is a large sum to check for at handover.

Once the association runs the complex, the monthly bill is set by its general body; our guide to society maintenance charges shows typical NCR rates.

When the builder drags its feet

Delays are common, often because the builder earns a margin on maintenance or still has unsold units. Your options:

• A RERA complaint against the promoter for failing sections 11(4) or 17, including an order to convey and hand over.
• In Maharashtra, MahaRERA can direct conveyance; deemed conveyance through the district deputy registrar remains available.
• In Haryana, the Town and Country Planning Department for AOA and declaration issues, and HRERA for the IFMS and handover.
• Consumer commissions for deficiency in service, where the claim is for compensation.

Where associations run into trouble

Forming the body is the easy part. Rival RWAs, a builder-friendly first committee elected before most owners moved in, and handovers signed without an audit are the usual failures. So is accepting common areas "as is": once you sign without a snag list, proving that a leaking basement was the builder's fault gets harder, even inside the five-year window. Common areas also bring disputes of their own, from terrace rights to parking rules, and the association has to settle policy on both early.

An association is not always the right fit for a small building. A block of eight flats may not reach Maharashtra's 10-member floor without the exemption route, and a four-floor builder floor rarely needs more than a registered agreement among owners on shared costs.

Frequently asked questions

When must the builder form the residents' association?

Under RERA section 11(4)(e), within three months of a majority of allottees booking, unless local law sets another rule. In Maharashtra, MahaRERA rule 9 makes the promoter apply to register the co-operative within three months of 51% booking. If your builder is past that point with nothing filed, a complaint to the state RERA authority is the direct route.

Should we register an AOA or an RWA in Haryana?

An AOA under the 1983 Apartment Ownership Act holds the owners' common interest in a building covered by a registered declaration; an RWA under the 2012 societies law is a voluntary welfare body. The two laws do not override each other. For taking over common areas and funds from a builder, the AOA route is usually the stronger one.

What documents must the builder hand to the association?

Title and conveyance papers, sanctioned plans, occupancy and completion certificates, the fire NOC, lift licences, electrical and pollution approvals, as-built drawings, equipment manuals and warranties, AMC contracts, audited accounts, and the IFMS, corpus and maintenance balances. Section 17(2) sets 30 days from the occupancy certificate where no local law applies.

Is the builder still responsible for defects after handover?

Yes. Section 14(3) of RERA makes the promoter fix structural defects and faults in workmanship, quality or services reported within five years of possession, free, within 30 days. If it does not, the allottee can claim compensation from the state RERA authority. A signed joint snag list at handover makes those claims much easier to prove.

Can the builder keep interest earned on our IFMS?

Not according to HRERA Gurugram, which ordered a builder to pay 11% a year on IFMS collected from a buyer, holding that keeping the interest was not permissible. Ask for a flat-wise IFMS statement with interest at handover. On a 300-flat complex with Rs 1.5 lakh per flat, the corpus is Rs 4.5 crore, so the interest is significant.

If you are buying into a complex where the handover is still pending, Realty Hunting can help you check how far it has got before you commit.
