RERA Four-Month Extension and Rising Building Costs: What Bangalore Flat Buyers Should Check
Steel, cement and labour became costlier through 2026, and developers asked for more time to finish registered projects. In August 2026 the Karnataka Real Estate Regulatory Authority (K-RERA) granted a four-month extension to eligible projects. This guide explains what that extension changes for a buyer of an under-construction flat in Bangalore, what it leaves untouched, and which clauses decide the outcome.
What Happened in 2026
The conflict in West Asia disrupted supply chains and pushed up the price of key building materials during the first half of 2026. Developer bodies wrote to the Union Ministry of Housing and Urban Affairs asking for three to six months of relief on project deadlines. The sequence that followed is set out below.
- 29 April 2026: the Department of Expenditure classified the West Asia situation as a war for force majeure purposes
- 31 July 2026: the Ministry advised state regulators to extend registration and completion timelines by four months
- 10 August 2026: K-RERA issued its order for Karnataka, numbered K RERA/ADMIN/10/2026, with immediate effect
The Karnataka order covers registered projects whose original, revised or extended completion date falls on or after 28 February 2026. Projects registered on or after 1 August 2026 are outside it. Promoters need no separate application, and no fee is charged for these four months.
How RERA Allows Extra Time
Every registered project carries a completion date that the promoter declared at registration. Section 6 of the Real Estate (Regulation and Development) Act, 2016 allows that registration to be extended in two situations.
- Force majeure, defined as war, flood, drought, fire, cyclone, earthquake or any other natural calamity that affects the regular development of the project
- Reasonable circumstances with no default by the promoter, for a period that cannot exceed one year in total
Higher input costs, a shortage of workers or slow sales are outside the force majeure definition. The 2026 relief rests on the word "war" in that definition. Section 7(3) lets the Authority keep a registration in force on terms it considers fit, and the August order relies on both sections.
What the Extension Changes
The order moves the completion date shown against the project on the K-RERA portal by four months. A project that was due in December 2026 now shows April 2027. The promoter stays in good standing with the regulator during that period and avoids the lapse of registration.
A buyer should open the project on the portal and note the new date. The quarterly progress updates on the same entry show how far each tower has come. A project that was already behind before February 2026 is unlikely to recover the gap in four months.
What It Leaves With the Buyer
The buyer's rights on delay come from section 18 of the Act and from the agreement for sale, and the registration is a separate matter. The Supreme Court made this distinction in Imperia Structures v. Anil Patni in November 2020. It held that the period for section 18 is counted from the date in the agreement, and an extension of registration does not change that.
Under section 18, a buyer whose flat is late may withdraw and take a refund with interest, or stay and receive interest for every month of delay. Rule 16 of the Karnataka rules sets the interest at the State Bank of India highest marginal cost of lending rate plus 2%. In Newtech Promoters v. State of Uttar Pradesh in November 2021, the Supreme Court described the right to a refund on demand as unconditional.
The agreement for sale has its own force majeure clause, and this is where the four months will be argued. The model form allows the possession date to move when a listed event delays the work. Whether the 2026 situation moved the date in a particular agreement is decided on the facts of that project, by K-RERA if the two sides disagree.
Can the Builder Raise the Price?
Rising costs lead some developers to ask existing buyers for more money. The model agreement for sale used in Karnataka describes the total price as free of escalation. It allows two kinds of increase only: taxes, and charges payable to a government or planning authority that are raised after the booking.
A demand linked to steel or cement prices falls outside both. A buyer who receives one should ask for the clause it relies on and reply in writing. Agreements that depart from the model form and carry a cost escalation clause should be questioned before signing, since the clause moves the builder's cost risk to the buyer.
Clauses to Read in the Agreement
Four parts of the agreement decide how a delay or a cost demand plays out. Reading them before paying the booking amount costs nothing.
| Clause | What to look for |
|---|---|
| Possession date | A calendar date, and whether a grace period is added to it |
| Force majeure | A list limited to the events in section 6, with no open-ended wording |
| Total price | An escalation-free price, with increases limited to taxes and authority charges |
| Delay interest | The same rate for the builder's delay as for the buyer's late payment |
The date in the agreement should match the completion date on the portal at the time of booking. A gap between the two, or a long grace period, deserves a written explanation from the developer.
Steps for a Buyer in an Affected Project
A buyer whose project falls under the August 2026 order can take a few simple steps now. They keep the options open if the delay grows.
- Note the old and new completion dates on the portal, with a dated screenshot
- Ask the developer in writing for the revised handover date of the tower and the reason for it
- Keep paying instalments only against construction milestones actually reached, as the payment schedule provides
- Refuse to sign a supplementary agreement that records a later possession date or waives delay interest without advice
- Plan for rent and pre-EMI interest over the extra months, using the EMI calculator to size the cost
- File a complaint with K-RERA under section 31 if possession passes the agreed date and no interest is offered
Buyers who act together through an association of allottees usually get clearer answers on timelines. The association may also ask the developer for the construction schedule that section 19 entitles every allottee to see.
Under-Construction or Ready Home?
A period of rising costs and extended deadlines changes the comparison between a flat under construction and a completed one. The first usually costs less at booking and spreads the payment over the build. The second has an occupancy certificate, a known handover date and no construction risk.
A fair comparison adds the rent paid during the wait and the interest paid before possession to the lower booking price. Where the gap narrows to a small amount, a completed home may be the steadier choice. Where the developer has a record of handing over on time and the agreement follows the model form, an under-construction flat still offers value.
