How to Check If a Builder Is RERA Registered

1What RERA Is and What It Covers

The Real Estate (Regulation and Development) Act, 2016 (RERA) established a statutory framework requiring builders, developers, and real estate agents to register with a state-level authority before marketing or selling residential or commercial projects. Karnataka operationalised the Act through the Karnataka Real Estate Regulatory Authority (K-RERA), which became functional in 2017. The authority maintains a public-facing portal at rera.karnataka.gov.in where every registered project's details are published and searchable by anyone.

RERA registration is not a quality certificate and it is not a guarantee of delivery. What it does provide is a legal record of the builder's declarations: the project layout, the number of units, the completion timeline, the approvals obtained, and the escrow account into which buyer funds must be deposited. When a builder is RERA registered, they are legally bound by those declarations. When they are not, there is no such accountability.

For homebuyers, RERA registration is the minimum baseline check that must be completed before any financial commitment. It precedes price negotiation, loan application, legal due diligence, and everything else in the purchase process. A project without valid RERA registration where registration is required should not receive a single rupee from a buyer until that status is resolved.

2Why Verification Matters Before You Pay

Builders routinely display RERA numbers on site hoardings, brochures, and sales presentations. The presence of a number is not sufficient. Homebuyers have discovered, after paying booking amounts, that the number displayed was for a different phase, a neighbouring project, or an entirely fabricated sequence. The verification step takes under five minutes and eliminates all three of those scenarios.

3Step-by-Step: How to Verify RERA Registration in Karnataka

The following steps apply to Karnataka projects. For projects in other states, the process is nearly identical but the portal URL differs. Links to Maharashtra, Telangana, and Tamil Nadu portals are provided in the FAQ section below.

4How to Read the RERA Project Detail Page

Finding a project on the RERA portal is only the first step. The detail page contains multiple data fields, and understanding what each one means is what converts a search result into actionable information. The following table identifies the most important fields and what to verify in each.

Pay particular attention to the "Proposed Date of Completion" field. Builders sometimes register a project with an aggressive completion date to satisfy the registration requirement, then seek extensions later. Check whether the project has any extension records on the portal. Multiple extensions without proportionate construction progress indicate execution risk.

The approved plans section is equally important. A registered project that has not uploaded its approved layout plan to the portal is technically in violation of RERA disclosure requirements. If plans are absent, ask the builder why. They may be pending approval from the local authority, which itself indicates the project does not yet have all necessary clearances.

5Red Flags That Require Immediate Caution

Beyond the basic pass or fail of whether a RERA number is valid, certain patterns in a project's RERA record indicate elevated risk. These are not automatic disqualifiers, but each one warrants specific clarification from the builder before you proceed.

6Cross-Checking Builder Claims Against the RERA Record

Sales representatives are trained to present a project in the most favourable light possible. RERA data gives you a second, independent account of the same project that the builder has submitted under legal obligation. Comparing the two surfaces inconsistencies that are worth addressing before you commit.

The most common discrepancies homebuyers encounter are around carpet area, total price components, and amenity commitments. The RERA record specifies carpet area per configuration type. If the builder's brochure quotes a different carpet area for the same configuration, the RERA figure is the legally binding one. Any shortfall in delivery below the RERA-declared carpet area entitles the buyer to either a proportionate price reduction or withdrawal with full refund.

Amenities are another area where builder marketing frequently exceeds what is declared on RERA. Builders often market amenities that are "proposed" or "subject to approval" as if they were confirmed. The RERA record reflects only what has been formally declared. If the club house, swimming pool, or commercial space shown in the brochure does not appear in the RERA project details, ask for written confirmation of their status and ensure the sale agreement specifically lists them as committed deliverables.

The Kaveri portal (Karnataka's property registration portal) offers a complementary check. If the builder or developer has sold units in earlier phases of the same project, those transactions are registered there. You can verify whether the prices declared in those registrations match what the builder is now quoting you for similar configurations. A significant gap between registered transaction prices and current asking prices warrants explanation.

7Using Transaction Data Alongside RERA Verification

RERA verification establishes whether a project is legally compliant. It does not tell you whether the price being quoted is in line with the market. For that, transaction data from the Sub-Registrar is the most reliable source available.

When a buyer registers a flat purchase at the Karnataka Sub-Registrar's office, the consideration amount (the actual sale price) becomes a permanent public record. These records are aggregated and made searchable through the PakkaBhav search tool. For any society with sufficient transaction history, you can see the price range within which similar flats have actually changed hands, the median price per square foot, and how recent the data is.

The combination of RERA and transaction data addresses two separate risks. RERA protects you against legal and structural risk: is this project legitimate, is the builder accountable, are the approvals in place? Transaction data protects you against price risk: is this price reasonable given what others have actually paid? A project can be fully RERA compliant and still be priced significantly above what comparable flats have sold for in the same locality. Both checks are necessary; neither alone is sufficient.

For under-construction projects where limited resale transaction data exists, the Ready Reckoner rate published by the Karnataka Stamps and Registration Department provides the government's own floor price estimate for the locality. Comparing the builder's asking price to the Ready Reckoner rate shows the premium being charged. Data from Bengaluru's established micro-markets shows that verified transaction prices for quality projects typically range from 20% to 60% above the Ready Reckoner floor, depending on the locality, builder reputation, and stage of construction. A premium of more than 80% above Ready Reckoner warrants careful scrutiny.

When negotiating with a builder, the combination of a RERA-verified project record and documented comparable transaction prices from the Sub-Registrar is the strongest analytical position available to a buyer. It removes the information asymmetry that builders and brokers rely on. The builder knows what similar flats have sold for. Now you do too.
