How to File a RERA Complaint Against a Builder in Karnataka , 2026 Guide

RERA (Real Estate Regulatory Authority) Karnataka was established to protect home buyers from builder defaults, project delays, and misrepresentation. If your builder has violated their RERA obligations, you have a legal right to file a complaint and seek compensation. This guide explains the process in 2026.

Grounds for Filing a RERA Complaint

You can file a complaint against a builder/promoter under RERA Karnataka for:

• Delay in delivery of possession beyond the RERA-registered date
• Misrepresentation of project specifications, amenities, or approvals
• Failure to provide Occupancy Certificate after possession
• Structural defects discovered within 5 years of possession
• Failure to register the project under RERA
• Failure to maintain the escrow account as required
• Unilateral modification of the agreement

Before Filing: Verify RERA Registration

First confirm the project is registered under RERA Karnataka at rera.karnataka.gov.in. Note the RERA registration number, the registered completion date, and the developer's contact details from the RERA portal. Also check if the project has filed its quarterly compliance reports , if not, this itself is a RERA violation you can include in the complaint.

Step-by-Step Complaint Process

1. Send a Legal Notice: Before filing at RERA, send a written legal notice to the builder via registered post or email, citing the specific violation and giving them 30 days to respond or rectify.
2. Gather Documents: Collect the Sale Agreement, payment receipts, RERA registration certificate of the project, any correspondence with the builder, and evidence of the violation (delayed possession letter, photos of incomplete construction, etc.).
3. File Online at RERA Karnataka Portal:
   • Visit rera.karnataka.gov.in
   • Register as a complainant
   • Select "File a Complaint" and choose the appropriate complaint type
   • Upload all supporting documents
   • Pay the complaint filing fee (currently ₹1,000 for individuals)
4. Offline Option: Complaints can also be filed in person at the RERA Karnataka office in Bengaluru by submitting Form C (complaint form) along with documents and the filing fee.

What Happens After Filing

RERA Karnataka will issue a notice to the builder and schedule a hearing. The process is quasi-judicial , both parties present their case before the RERA authority. RERA is required to adjudicate complaints within 60 days (though extensions are common). If the complaint is upheld, RERA can order:

• Refund of amount paid with interest at the prescribed rate (currently SBI MCLR + 2%)
• Compensation for mental agony, loss, and legal costs
• Specific performance (directing the builder to complete the project and give possession)
• Penalty on the builder

Appeals

Any party aggrieved by a RERA order can appeal to the Real Estate Appellate Tribunal (REAT) within 60 days of the order. Further appeals can be made to the High Court.
