What is RERA?

The Real Estate (Regulation and Development) Act, 2016 (RERA) is India's landmark legislation designed to protect homebuyers and bring transparency to the real estate sector. Karnataka was among the early adopters, establishing K-RERA (Karnataka Real Estate Regulatory Authority) to enforce compliance.

If you're buying property in Bangalore or anywhere in Karnataka, understanding RERA is not optional — it's essential.


What Does RERA Cover?

Projects That Must Be Registered

  • Any real estate project with more than 8 apartments or land exceeding 500 square meters
  • Both residential and commercial projects
  • Projects where construction is ongoing (not completed before RERA came into effect)

What Developers Must Disclose

  • Project plans approved by the competent authority
  • Stage-wise completion timeline
  • Details of the architect, contractor, and structural engineer
  • History of past projects and their completion status
  • Prorated carpet area calculation
  • Details of encumbrances and litigation, if any

How to Verify a RERA Registration

Follow these steps to verify any property before investing:

Step 1: Visit the Karnataka RERA Portal

Go to rera.karnataka.gov.in

Step 2: Search by RERA Number

  • Click on "Registered Projects" or "Search Project"
  • Enter the RERA registration number provided by the developer
  • You can also search by project name, promoter name, or district

Step 3: Review the Certificate

Check the following details on the certificate:

  • Project name and location — must match what the developer advertises
  • Promoter/Developer name — verify it's the same entity you're dealing with
  • Registration validity — ensure it hasn't expired
  • Approved plan details — number of floors, units, etc.
  • Completion deadline — this is legally binding

Step 4: Check for Complaints

On the same portal, check if any complaints have been filed against the project or developer. This is a critical due diligence step.


Your Rights as a Homebuyer Under RERA

1. Right to Information

Developers must disclose all project details on the RERA website. You have the right to access:

  • Approved layout plans and specifications
  • Project timeline and current status
  • Financial details of the project

2. Carpet Area Transparency

RERA mandates that pricing must be based on carpet area (the actual usable area), not super built-up area. This eliminates the common practice of inflating area measurements.

3. Timely Possession

If a developer fails to deliver on time, you're entitled to:

  • Full refund with interest (SBI marginal cost + 2%)
  • OR continue with the project and receive compensation for the delay

4. Structural Defect Warranty

For 5 years after possession, the developer must fix any structural defects or poor workmanship at no cost to you.

5. Protection of Your Money

Developers must deposit 70% of project funds in a separate escrow account, ensuring your money is used only for that specific project — not diverted elsewhere.


Common Red Flags to Watch For

Red FlagWhat It Means
No RERA number displayedProject may be unregistered (illegal for qualifying projects)
Expired RERA registrationProject hasn't been completed or extended properly
Multiple complaints on portalHistory of buyer dissatisfaction
Mismatch in project detailsWhat's advertised vs what's on RERA doesn't match
"Pre-launch" pricingRERA prohibits marketing before registration
Asking for >10% before agreementRERA limits advance payment to 10% of property cost

How to File a RERA Complaint

If you have a grievance against a developer, here's the process:

Step 1: Attempt Resolution

First, send a written complaint to the developer. Keep records of all communication.

Step 2: File Online

Visit rera.karnataka.gov.in → Click "Complaints" → Fill the online form with supporting documents.

Step 3: Hearing

K-RERA will schedule a hearing. Both parties get an opportunity to present their case.

Step 4: Order

K-RERA issues a legally binding order. Non-compliance by the developer can attract penalties including imprisonment.

Filing Fees

  • Individual complaint: ₹1,000
  • Association/group complaint: ₹5,000

RERA vs Non-RERA: The Risk Comparison

FactorRERA RegisteredNot Registered
Legal protection✅ Full RERA protection❌ No regulatory recourse
Price transparency✅ Carpet area based❌ Often super built-up
Completion guarantee✅ Legally binding deadline❌ Dependent on developer goodwill
Money safety✅ 70% in escrow❌ No safeguard
Resale value✅ Higher trust = better value❌ Lower buyer confidence

Practical Tips for Bangalore Buyers

  1. Never pay more than 10% before signing the agreement for sale
  2. Always ask for the RERA number before visiting a property site
  3. Cross-verify online — don't just take the developer's word
  4. Check completion deadline — is it realistic given the current construction stage?
  5. Verify the approved plan — does the actual model/plan match the RERA-registered plan?
  6. Use AnviRealty's RERA verification links on property detail pages for one-click verification
