RERA in Karnataka — Registration Lookup, Complaints & 2026

RERA Karnataka: In Karnataka, the Real Estate Regulatory Authority is K-RERA, headquartered in Bengaluru on J.C. Road. K-RERA has registered over 28,000 projects, accepts e-signature complaints, and charges ₹1,000 per project. Always verify on rera.karnataka.gov.in before paying token money.

What is Karnataka RERA

The Karnataka Real Estate Regulatory Authority (K-RERA) was constituted on 10 July 2017 under the central RERA Act, headquartered in Bengaluru at 1/14, Silver Jubilee Block, Unity Building, JC Road. K-RERA is widely regarded as among the more procedurally active state authorities — it has registered over 28,000 projects and 35,000 agents since inception, runs a fully online filing system, and was an early adopter of e-signature acceptance.

For Bengaluru buyers, K-RERA matters disproportionately because Karnataka contributes nearly a fifth of all residential project registrations in southern India. Almost every project on the Sarjapur–Whitefield–North Bengaluru axis is K-RERA registered. The Authority publishes a quarterly defaulters list of promoters who fail to file Quarterly Progress Reports.

Karnataka RERA portal & verification steps

The official portal is rera.karnataka.gov.in ↗. Six-step verification:

1. Visit the portal and click "Registered Projects".
2. Search by project name (partial match works) or paste the full registration number.
3. Verify registration date, validity (proposed completion), promoter PAN, sanctioned plan PDF, Form-3 CA certificate.
4. Click "Quarterly Updates" — confirm the most recent QPR is within the last 90 days. Older = red flag.
5. Check "Complaints" tab for any pending or disposed complaints against the project.
6. Cross-verify the promoter on the relevant sub-registrar portal for title-deed chain.

Always verify on the official .gov.in domain — never trust a builder microsite, broker WhatsApp forward, or any third-party "RERA-approved" claim.

How to file a RERA complaint in Karnataka

Filing fee: ₹1,000 per project.

1. Register on the K-RERA portal as a complainant. KYC with Aadhaar + PAN.
2. Pay the filing fee through the portal payment gateway.
3. Upload the complaint with allotment letter, sale agreement, all payment receipts, and the builder's possession commitment letter.
4. The Authority issues notice to the promoter — typically within 30–60 days.
5. Hearings scheduled at the K-RERA office or via video conference.
6. Order issued — statutory target 60 days, in practice longer.

Notable Karnataka RERA cases & enforcement

• Mantri Developers vs. allottees (2019–2023): K-RERA repeatedly directed Mantri to refund buyers in stalled Energia, Synergy and Serenity projects with Section-18 interest at SBI MCLR + 2%. Several orders progressed to NCLT under Section 7 of IBC after non-compliance.
• Total Environment vs. allottees (2020–2022): K-RERA pulled up the developer over delayed possession in projects on Hennur and Yelahanka belt; ordered project-wise escrow audits.
• K-RERA has imposed cumulative penalties exceeding ₹100 crore across promoters for non-registration, late QPR filing, and false advertising.

Karnataka RERA registration number format

The K-RERA registration number follows the pattern PRM/KA/RERA/{tier}/{ward}/PR/{ddmmyy}/{serial}. Example: PRM/KA/RERA/1251/446/PR/220422/004789.

Always paste the FULL alphanumeric string into the portal search box — partial matches frequently fail. Treat any project listed only with a "RERA approved" tag and no actual number as unregistered until proven otherwise.

Karnataka-specific quirks every buyer must know

• K-RERA accepts e-signature on both promoter filings and complainant filings — one of only 4 states that does so cleanly.
• Karnataka mandates project-specific escrow with a Karnataka-scheduled bank; out-of-state escrow accounts trigger automatic registration rejection.
• K-RERA publishes a quarterly defaulters list — promoters with overdue QPRs are publicly named.
• Plotted developments above 500 sqm must be registered, and K-RERA actively enforces this on Devanahalli–Doddaballapur layouts.
• K-RERA registration does NOT cover BDA / BMRDA / DTCP layout approval — verify separately.
