The Real Estate (Regulation and Development) Act

Before the Real Estate (Regulation and Development) Act came into force in 2016, buying an under-construction property in India meant trusting a developer with lakhs of rupees and no legally enforceable right to get them back if the project failed. Developers used apartment buyer money to fund other projects, delivered properties years after promised dates without any penalty, and quoted super built-up area rather than carpet area so that the effective price per usable square foot was significantly higher than the advertised number. RERA addressed all three of these structurally. It is not a perfect law — enforcement quality varies and some developers find workarounds — but understanding what RERA gives you, how to use it, and what it does not cover is essential for any Karnataka property buyer in 2026.

This guide covers the Karnataka RERA (K-RERA) framework in full: which projects must register, the escrow account that protects your money, the carpet area definition that changed pricing language, your specific legal rights under the Act with the relevant section numbers, the delay compensation formula, the five-year structural defect liability, and the complete complaint filing process with fee and timeline.

Why RERA Exists — The Problems It Was Designed to Solve

The pre-RERA real estate market in Karnataka, and India broadly, had three structural failures that consistently harmed buyers while benefiting developers:

Fund diversion: A developer would collect twenty percent booking amounts from buyers across ten projects simultaneously, using the funds from Project A to finance the construction of Project B, and from Project B to fund Project C. When any one project hit a cash flow problem, the entire chain was exposed. Buyers who had paid full or near-full booking amounts found their developer insolvent and their money gone — with only civil court remedies that took years to produce any recovery. RERA's response: developers must park seventy percent of all project collections in a separate, ring-fenced bank account that can only be used for the land and construction costs of that specific project. The account requires a chartered accountant's audit before withdrawals above a threshold. Fund diversion became a RERA violation with criminal liability.

Misleading area representation: Developers routinely quoted prices in rupees per super built-up area — a figure that includes the buyer's proportional share of common areas (lobby, corridors, lift shafts, club areas). A flat quoted at ₹6,000 per sq ft at 1,200 sq ft SBUA might have only 850 sq ft of actual usable (carpet) area, making the effective price ₹8,470 per sq ft of what the buyer actually occupied. RERA mandated pricing on carpet area — the net usable floor area of the apartment, excluding walls, balconies beyond a specified area, and common areas. This forced pricing transparency and allowed buyers to compare across projects on the same basis.

Unaccountable delays: Before RERA, a developer who missed their possession date by two or three years faced no mandatory financial consequence. The buyer's remedies were limited to civil suits that cost time and money the buyer had often already spent. RERA introduced mandatory compensation for delayed possession at a rate of the SBI Marginal Cost of Lending Rate (MCLR) plus two percent per annum on the amount paid — making delays financially costly for developers rather than merely inconvenient for buyers.

Which Projects Must Register Under RERA Karnataka?

The registration threshold in Karnataka applies to any real estate project that exceeds either of these criteria: a plot area above five hundred square metres, or more than eight apartments across all phases of the project. If a project meets either threshold, the developer must register with K-RERA (Karnataka's state RERA authority) before advertising, marketing, booking, or selling any unit.

A developer who markets or sells without RERA registration is in direct violation of the Act. The legal consequence: all bookings taken before RERA registration are recoverable by buyers, and the developer faces penalties up to ten percent of the project's estimated cost per violation, and up to three years imprisonment for continuing violations.

Real estate agents (brokers) facilitating sales of RERA-registered projects must also be individually registered with K-RERA. The agent registration requires PAN, Aadhaar, a certificate or registration fee, and creates a unique agent registration number that must appear in all marketing communications for RERA projects. An agent who is not RERA-registered and facilitates a sale in a RERA-mandated project is acting in violation — a signal about their overall compliance approach that buyers should take seriously.

Importantly, RERA does NOT apply to resale properties. A resale transaction between two individuals — even for an apartment in a RERA-registered project — is outside RERA's scope. RERA applies only to the original developer-to-buyer sale during the under-construction phase.

The 70% Escrow Account — Your Money's Protection

Section 4(2)(l) of the RERA Act mandates that developers deposit seventy percent of all amounts collected from buyers — for both the project's land cost and construction cost — into a separate dedicated bank account (frequently called the escrow account or separate account). This account can only be used to meet land and construction costs of that specific project. Withdrawal from this account requires certification from a licensed engineer, an architect, and a chartered accountant that the withdrawal amount corresponds to the percentage of construction completed.

The practical protection this provides: even if the developer's parent company or other projects face financial trouble, the seventy percent ring-fenced in your project's dedicated account cannot be seized by creditors of those other projects. It remains available for your project's construction. The thirty percent the developer retains can cover their overhead, marketing, and profit — but two-thirds of what you paid is structurally protected for the purpose you paid it for.

What to verify on the K-RERA portal before booking: check whether the project's registered details show a dedicated account number. The account details should be disclosed on the project's RERA page. A project whose RERA page does not show this disclosure has a compliance gap that is worth questioning before payment.

Carpet Area Under RERA — What Changed and Why It Matters

Section 2(k) of the RERA Act defines carpet area as the net usable floor area of an apartment, excluding the area covered by the external walls, the area under services shafts, exclusive balcony or verandah areas, and exclusive open terrace areas. In simpler terms: carpet area is the area of floor you can actually lay carpet on — the usable space you occupy, not the walls that surround it or the lobbies that connect you to the lift.

Under RERA, developers must quote prices in terms of carpet area. All sale agreements under RERA must specify the carpet area of the apartment being sold. If a developer quotes super built-up area in their marketing — which many still do — they must also disclose the carpet area separately and the sale price must be stated in carpet area terms in the formal agreement.

The practical implication for buyers: when comparing a RERA-registered project's price with another project's price, ensure you are comparing the same metric. A project quoting ₹7,500 per sq ft SBUA at a loading factor of thirty percent is effectively ₹9,750 per sq ft carpet area. A project quoting ₹9,500 per sq ft carpet area is ₹250 per sq ft carpet more expensive — but the super built-up comparison would have shown it as twenty-seven percent cheaper. Always get the carpet area number and calculate the carpet area price for honest comparison.

Your Specific Legal Rights as a Buyer Under K-RERA

Right to Information (Section 11): Developers must disclose on the RERA portal: the project's approved plans and layout, the specifications of construction and materials, the proposed facilities and amenities, the project's completion date, all approvals received (including government and statutory approvals), and the state of encumbrance on the land. You have the legal right to access all of this information before committing to a purchase. A developer who withholds project information or provides information that differs from the RERA portal disclosure is in violation.

Right to Possession by the RERA Date (Section 18): The developer's RERA registration specifies a project completion date. This is a legally committed date — not an aspirational marketing timeline. If the developer fails to deliver possession by this date, you have the right to either withdraw from the project and receive a full refund with interest, or continue with the project and receive interest compensation for the delay period.

The interest rate for both refund and delay compensation under K-RERA is the SBI Marginal Cost of Lending Rate (MCLR) plus two percentage points per annum on the amount paid. On a ten lakh rupee payment, if the project is one year delayed, the compensation is approximately ten lakh multiplied by (SBI MCLR + 2%) — currently approximately eleven to eleven point five percent per annum — amounting to approximately one lakh ten thousand to one lakh fifteen thousand rupees in interest compensation. For large-value bookings, this compensation is meaningful and creates genuine financial incentive for developers to deliver on time.

Right to Withdraw With Full Refund (Section 18): If the developer defaults on delivery, you can choose to withdraw from the purchase entirely. The developer must refund the entire amount paid within forty-five days of the withdrawal notice, along with interest at the MCLR plus two percent rate from the date of each payment. This is a more powerful remedy than most buyers realise — the full refund plus interest at market-linked rates effectively means holding the developer's money costs them real money.

Five-Year Structural Defect Liability (Section 14(3)): After possession is handed over, the developer remains liable for any structural defect, defect in workmanship, quality, or provision of services — for a period of five years from the date of possession. If a structural problem emerges within this five-year period, the developer must rectify it free of cost within thirty days of receiving the written complaint. If the developer fails to rectify within thirty days, the buyer is entitled to compensation.

This provision is frequently invoked in Karnataka for issues including: cracks in walls or slabs that emerge within the first two to three years of occupation; waterproofing failures in roof or bathroom areas; plumbing and electrical faults that are not attributable to the buyer's own modifications; and defects in the promised amenities (gym equipment not installed to specification, clubhouse facilities below the contracted standard). The five-year window is significant — a problem that emerges at year four is still within the liability period.

Right to Complain (Section 31): Any person aggrieved by a developer's violation of the Act or the terms of a RERA-registered project can file a complaint with the K-RERA Authority. The complaint is against registered projects — resale transactions, pre-RERA projects, and projects below the registration threshold are outside the complaint mechanism.

How to File a RERA Complaint in Karnataka — Step by Step

The complaint process is entirely online and can be completed without a lawyer, though legal representation is advisable for complex matters or large-value claims.

Step 1 — Confirm eligibility: Your complaint must relate to a K-RERA registered project. Verify the project's registration on rera.karnataka.gov.in before proceeding. Common valid complaints: delayed possession beyond the RERA registration date; structural defects within five years of possession; developer failing to provide agreed facilities; misleading advertising or specification changes from what was disclosed on RERA; failure to refund after agreement termination.

Step 2 — Gather supporting documents: Assemble your sale agreement (registered builder-buyer agreement or agreement for sale), all payment receipts showing amounts paid and dates, any correspondence (emails, letters, WhatsApp messages, notices) with the developer regarding the issue, the RERA registration number of the project, and proof of possession (if you have taken possession) or proof of non-possession beyond the RERA date.

Step 3 — Register on the K-RERA portal: Go to rera.karnataka.gov.in and click Register. Create an account with your mobile number and email. Verify your email. Login to access the complaint filing section.

Step 4 — File the complaint: Navigate to Register Complaint. Enter the project RERA registration number, the developer's name, and the nature of the complaint (select the applicable category — delay, defect, refund, false advertising). Upload all supporting documents in PDF format. Pay the complaint filing fee of one thousand rupees through the portal's payment gateway. Submit and note the complaint reference number.

Step 5 — Track and attend hearings: K-RERA typically schedules a hearing within sixty days of complaint registration. Both parties are given the opportunity to present their case. The RERA Authority may summon the developer, call for evidence, and inspect the project. The Authority's order is typically passed within ninety days, though complex cases can take longer. Keep your complaint reference number and attend all scheduled hearings.

What Happens After a K-RERA Order Is Passed?

If the K-RERA Authority passes an order in your favour — directing the developer to pay compensation, refund money, or complete construction — and the developer does not comply within the specified period, you can apply for the order to be enforced. An unreasonably non-compliant developer faces attachment and sale of assets to satisfy the order.

If you disagree with the K-RERA Authority's order, or if the developer appeals it, the next level is the Karnataka Real Estate Appellate Tribunal (KAREAT). KAREAT hears appeals from K-RERA orders within sixty days of filing the appeal. If KAREAT's order is also challenged, the next level is the Karnataka High Court. The escalation mechanism is: K-RERA Authority → KAREAT → High Court.

RERA vs Consumer Court — Which Forum Should You Use?

Both RERA and the Consumer Forum (under the Consumer Protection Act 2019) offer remedies for real estate grievances. Understanding which to use depends on what you want to achieve:

Use RERA when: The project is RERA-registered; your complaint is specifically about delayed possession, structural defects, specification changes, or refusal to refund; you want a faster, more specialised resolution from a real estate-specific regulator; and you want the resolution within the sixty to ninety day RERA timeline rather than the longer consumer court process.

Use the Consumer Forum when: The project is not RERA-registered (or completed before RERA); you want to claim compensation for consequential damages (rent paid during the delay period, for example) beyond what RERA typically orders; or RERA has already passed an order and you want additional compensation under Consumer Protection law. Consumer courts can award damages for mental agony and harassment in addition to the principal refund and interest — RERA's compensation is more strictly limited to the interest formula.

Filing a complaint in both forums simultaneously is permitted — the principle of simultaneous civil remedies applies, and many buyers use RERA for the faster mandatory compensation while pursuing the consumer forum for additional consequential damages.

What RERA Does NOT Cover — The Explicit Exceptions

Understanding what falls outside RERA prevents wasted effort and misplaced expectations:

Resale properties: Any property you buy from an individual seller rather than a developer is outside RERA entirely. The legal framework for resale transactions is the Transfer of Property Act, the Registration Act, and Karnataka-specific property laws — not RERA.

Projects below the threshold: A building with eight or fewer apartments, or a plot development covering five hundred square metres or less, is not required to register under RERA. Smaller boutique developers who fall below this threshold operate outside RERA's regulatory framework. Buyers of these smaller developments rely on contractual remedies rather than RERA's statutory protections.

Projects completed before RERA (pre-May 2017 for Karnataka): Projects for which Occupancy Certificates were received before RERA came into effect in Karnataka are exempt from RERA registration requirements. Buyers of such completed properties have no RERA complaint avenue.

Renovation of existing properties: A contract to renovate an existing property, build interior works, or alter an existing structure is not a real estate development project under RERA. Contractor disputes for renovation work fall under standard contract law, not RERA.

Frequently Asked Questions: RERA Karnataka 2026

Which real estate projects must register under RERA Karnataka?

Any project with a plot area above five hundred square metres, or with more than eight apartments across all project phases, must register with K-RERA before advertising or selling. Registration is mandatory before any marketing, booking amount collection, or sale agreement. A developer who sells without RERA registration is in violation and all bookings taken before registration are recoverable by buyers with interest.

What is the compensation rate for delayed possession under RERA Karnataka?

The compensation rate is the SBI Marginal Cost of Lending Rate (MCLR) plus two percentage points per annum on the amount paid. If you paid Rs 50 lakh and the project is one year delayed, compensation is Rs 50 lakh multiplied by (SBI MCLR + 2%) per annum — approximately Rs 5.5 to Rs 5.75 lakh for one year at current MCLR rates. You can choose between this ongoing compensation or a full refund with interest at the same rate on all payments made.

What does the 70% escrow account requirement mean for buyers?

Under Section 4(2)(l) of RERA, developers must park seventy percent of all amounts collected from buyers into a dedicated bank account that can only be used for the land and construction costs of that specific project. Withdrawal requires certification from a licensed engineer, architect, and chartered accountant confirming the construction progress. This prevents fund diversion — the developer cannot use money from your project to fund another. The remaining thirty percent the developer retains covers overhead and profit.

How do I file a complaint with RERA Karnataka for a delayed project?

Go to rera.karnataka.gov.in and create an account. Navigate to Register Complaint, enter the project's RERA registration number and developer details, select the complaint category (delayed possession for this situation), upload your sale agreement, payment receipts, and any correspondence with the developer. Pay the Rs 1,000 complaint filing fee. Submit and note the complaint reference number. K-RERA typically schedules a hearing within sixty days. Keep all documents and attend all scheduled hearings.

Does RERA apply to resale properties and pre-2017 projects in Karnataka?

No on both counts. RERA applies only to new development projects registered with K-RERA — the original sale from developer to buyer during the under-construction phase. Resale transactions between individuals are governed by the Transfer of Property Act and Registration Act, not RERA. Projects that received Occupancy Certificates before RERA came into effect in Karnataka (broadly before May 2017) are exempt from RERA registration and outside the complaint mechanism.

Filing a K-RERA complaint is only the first step when a developer violates commitments — resolving property disputes in Karnataka covers what happens after the complaint, including execution proceedings when developers ignore K-RERA orders.

RERA governs the developer-buyer relationship during construction, but after possession the Karnataka Apartment Ownership Act takes over — understanding both laws gives buyers protection across the full transaction lifecycle.

RERA registration does not resolve pre-existing easement disputes on the underlying land — buyers of RERA-registered apartments in layouts bordering older properties should review our overview of land easements and property rights in Karnataka before finalising purchase.
