Editorial note: Originally drafted in February 2026 and published as part of The Tamvada Brief archive.

The Real Estate (Regulation and Development) Act, 2016 — RERA — became operational on 1 May 2017. For the first time, India had a regulator dedicated to the real estate sector, with binding registration, mandatory disclosure, escrow of buyer money, and a quasi-judicial appellate forum. Eight years in, RERA has matured into a working compliance regime in most south Indian states, though the texture differs from state to state.

This blog is the working map a Bangalore buyer or a Chennai builder should have in their head before the next transaction.

The architecture in one paragraph

RERA is a central Act with state Rules — labour-style. The Real Estate (Regulation and Development) Act, 2016 is the parent statute. Each state notifies its own Rules (e.g., the Karnataka Real Estate (Regulation and Development) Rules, 2017) and establishes its State Real Estate Regulatory Authority (Karnataka RERA, Tamil Nadu RERA, etc.) and Real Estate Appellate Tribunal. Sections 31 to 38 of the Act govern the authority; Sections 43 to 58 govern the tribunal; Section 40 governs penalties.

For a buyer or builder, three sections do most of the heavy lifting: Section 3 (registration), Section 4 (project disclosure), and Section 18 (refund and compensation).

Section 3 — what must be registered

Section 3 of the 2016 Act prohibits a promoter from advertising, marketing, booking, selling or offering for sale a plot, apartment or building in a real estate project without registering the project with the State RERA. The thresholds:

The project area exceeds 500 square metres, OR
The number of apartments to be developed exceeds eight

For all but the smallest projects, registration is therefore mandatory. The penalty for non-registration under Section 59 is up to 10% of the estimated project cost, and continued non-registration after the order — imprisonment up to three years, or further fine up to 10%, or both.

Registration requires the promoter to submit a battery of documents — title deed, encumbrance certificate, sanctioned plans, approvals, declaration of project completion timeline, agreement-for-sale draft, and the proposed allotment letter. The registration carries a unique RERA project number that every advertisement, brochure and agreement must display.

Section 4 — the disclosure obligations

Section 4 lists the disclosures the promoter must make at the time of project registration. The list is long but in practice the operative items are:

Layout plan and sanctioned plan
Stage-wise schedule of completion
Status of approvals (commencement certificate, environmental clearance, etc.)
Carpet area of each apartment (and not merely super built-up area)
Names of the architect, engineer, contractor
Quarterly updates to the State RERA portal — work progress, financial status, and any change to plans

The quarterly update obligation is the one most often missed. State RERAs in Karnataka and Tamil Nadu have penalised dozens of projects for non-compliance with quarterly disclosure alone.

Section 4(2)(l)(D) — the 70% escrow rule

Embedded in Section 4(2)(l)(D) is the most important financial discipline of RERA: 70% of the amount realised from buyers for a project must be deposited in a separate escrow account and used only for the cost of construction and land. The promoter cannot deploy buyer money on other projects or general working capital.

Withdrawal from the escrow account requires a certified architect’s certificate, engineer’s certificate, and chartered accountant’s certificate confirming that the percentage of completion of the project matches the percentage of withdrawal. This three-certificate gate is the single biggest operational change RERA brought to Indian real estate.

Section 18 — when the project is delayed

This is the buyer’s most-used remedy. Section 18 of the 2016 Act provides that if the promoter fails to complete or is unable to give possession of an apartment as per the agreement for sale, the allottee may:

Withdraw from the project and demand a refund of the entire amount paid with interest at the prescribed rate plus compensation, OR
Continue in the project and claim interest at the prescribed rate for every month of delay till handover

The prescribed rate is set by the State RERA. In Karnataka it is typically the SBI MCLR + 2%; in Tamil Nadu, similar. The economic effect is that delayed projects pay buyers a yield on their paid-in amount that often exceeds what the buyer could have earned in any deposit alternative.

The Supreme Court in Newtech Promoters and Developers Pvt Ltd v State of UP (2021) confirmed that Section 18 confers a right on the allottee that the promoter cannot diminish through any contract clause. The provision is statutory and unwaivable.

State-by-state texture in south India

Karnataka RERA (KRERA) — Established 2017. Operates from Bangalore. Has been one of the most active state authorities — over 5,000 projects registered by end-2024 (verify), and a steady caseload of complaints under Section 31. KRERA’s enforcement against non-registration has been visible.

Tamil Nadu RERA (TNRERA) — Established 2017. Operational from Chennai. Significant pendency in early years; case disposal has improved. Tamil Nadu Rules 2017 are largely aligned with the parent Act, with some local variation on quarterly disclosure formats.

Telangana RERA — Operational. The Hyderabad real estate market’s growth has produced a meaningful complaint volume.

Andhra Pradesh RERA — Operational but variable in implementation across the state’s two real-estate hubs.

Kerala RERA — Operational. Smaller project volumes than Karnataka or Tamil Nadu.

For a buyer in any south Indian metro, the key practical fact is: the State RERA is your forum, not the consumer commission. Section 71 of the 2016 Act provides for a single-window adjudication; Section 79 bars the civil court’s jurisdiction over matters covered by the Act.

Where builders most often slip

In our practice, the same five issues recur:

Booking before registration. A builder takes advance from a buyer before the project is RERA-registered. Section 3 contravention.
Advertising super built-up area. Section 4 mandates carpet area in the disclosure. Old habit dies hard.
Withdrawing from escrow without certificates. The three-certificate gate is procedural but binding. Many small builders treat it as a formality and run into Section 4(2)(l)(D) actions.
Failure to file quarterly updates. Continuing offence; Section 60 penalty up to 5% of project cost.
Delayed handover without Section 18 settlement. Builders who let the delay drift accumulate compounding interest liability under Section 18 that becomes balance-sheet-meaningful.

Where buyers most often miscalculate

Not checking the RERA portal before paying. Every state RERA hosts the project registration database online. A 10-minute check would prevent many disputes.
Paying in cash beyond limits. RERA does not displace tax law. Cash payments above Rs 20,000 attract income-tax issues regardless of RERA registration status.
Treating the agreement for sale as the only document. Section 13 prohibits the promoter from accepting more than 10% of the cost without a registered agreement for sale. Without registration, the legal position is weak even if the agreement itself is sound.
Filing in the consumer commission. With limited exceptions, the State RERA is the correct forum for RERA-covered grievances.

Counter-position to flag

The relationship between RERA and the Consumer Protection Act 2019 has had judicial flux. The Supreme Court in M/s Imperia Structures Ltd v Anil Patni (2020) and subsequent cases has held that consumer fora and RERA forums have concurrent jurisdiction in defined cases — the buyer may choose. This is contested in some High Courts; the practical advice remains that RERA is the specialised forum and the first choice for RERA-covered claims.

What every buyer should do before signing

Check the project on the State RERA portal. Registration number, status, quarterly updates current.
Verify the agreement for sale. Does it conform to the model agreement in the State Rules? Are deviations in your favour?
Verify the carpet area. Section 4 carpet area should match the agreement. Super built-up area variation is a red flag.
Confirm escrow. Is the project’s 70% escrow account separately specified?
Document everything in writing. Verbal promises by sales teams are not enforceable; RERA agreements are.

What every builder should do this quarter

Audit all current projects for Section 3 registration status. Any project above 500 sqm or 8 units that is not registered — register or stop marketing.
Bring all quarterly disclosures current. Backlog is treated severely.
Operationalise the three-certificate withdrawal protocol. Make it routine.
Audit advertising materials for carpet area and RERA number compliance. Every brochure, every banner, every Instagram post.
Maintain a Section 18 dashboard. Project-by-project timeline against agreed-handover dates, with early-warning thresholds.

The bottom line

RERA changed Indian real estate from a caveat-emptor industry to a disclosure-driven, escrow-disciplined regulated sector. It is not perfect — pendency in some states is real, and enforcement varies. But it is now the operative compliance regime, and any south Indian buyer or builder who treats it as optional pays for that mistake at the State RERA later.
