Plan Deviation Rules in Bangalore 2026: What Home Buyers Need to Know

Thousands of Bangalore buildings were finished larger, taller or nearer the boundary than the drawings the city sanctioned. Across April and May 2026 the state and the city authority set out a plan to tolerate more variation and to open one window for owners to clear old breaches. Read on for the rules as announced, the harm an unresolved deviation does to a purchase and the paperwork to ask for in Bangalore.

Why the certificate matters

The sanctioned plan records the permitted height and the setbacks, meaning the open strips around a building, along with the FAR (floor area ratio). If a structure goes past the allowed margin, it may be denied the occupancy certificate (OC), the paper that formally clears it for occupation. Until 2026 the margin was 5 per cent.

Banks take the OC seriously, so a home without one is harder to finance and to resell. Announcing the reform in May 2026, the state referred as well to a Supreme Court ruling that rules out power and water connections for such buildings.

The city authority, the GBA, has put the number of properties without an OC at roughly 3 to 3.5 lakh, since their deviations crossed the old limit. Many of them are ordinary family homes.

The draft of 1 April 2026

In April 2026 the GBA notified draft building bye-laws, an amendment to the Bengaluru City Corporation rules, and objections were taken till 30 April 2026. The figure of 15 per cent is not universal. These are the limits:

• Setback shortfall may total 15 per cent, though the most any one side can lose is half its required setback
• Buildings below 15 metres on plots no larger than 500 sq m can deviate by 15 per cent in FAR
• Taller buildings on larger plots get only 5 per cent in FAR
• Height deviation is capped at 7.5 per cent across the board
• Added floors cannot be regularised under any heading

Penalties are computed differently as well. The fee no longer follows construction cost. It is tied to the guidance value of the excess area, in a range of 3 to 10 per cent for homes and 6 to 12 per cent for commercial buildings.

The settlement window

Along with the wider tolerance, Deputy Chief Minister D.K. Shivakumar announced a single settlement round for earlier deviations on 13 May 2026. The scheme was to accept applications from 15 June 2026 for around three months. Anyone applying in that period gets a 50 per cent concession on the charges.

After scrutiny and payment, OCs follow for buildings that now fall within the limit. The government hopes to close the exercise by June 2027. What applies to a given building will be settled by the final bye-laws and the scheme rules.

Buckets for a deviation

Every breach lands in one of three buckets, and the bucket decides what must happen before a purchase is safe:

• Within the tolerance: an OC becomes possible when the measurements are accepted
• Bigger but covered by the scheme: the owner applies, faces scrutiny and pays the penalty to cure it
• Past any scheme, for instance an additional storey or a deep setback violation: the defect remains, with trouble for loans and resale

Merely being regularisable is not the same as being regularised. The benefit starts after the owner applies, pays and gets the order.

Papers for an existing home

On a resale flat or an independent house, put these requests to the seller before any money moves:

• The OC together with the sanctioned plan, whose number is checked at the office that approved it
• An engineer's or architect's comparison of the standing building and the plan, expressed as a percentage
• A walk-through to spot an added floor, a covered setback, parking changed into rooms or shops and a larger footprint
• For a deviation said to be under regularisation, the application, proof of payment and the final order
• A written agreement on who bears the penalty while the process runs, or a price reduction that covers it
• Your bank's reply, early, on whether it will lend against that building

Khata is a different matter altogether. Turning a B-khata into an A-khata corrects the record of the property, whereas regularisation corrects the building as built. A home may be fine on one count and faulty on the other.

Flats not yet built

A buyer here depends on what the builder delivers after the sale. The wider tolerance tells the city what it may accept, but it gives the builder no licence to change the home sold. What protects the buyer is the sanctioned plan of the project and the sale agreement.

Check that the project is registered with Karnataka RERA, study its listed approvals and ensure possession is linked to a valid OC. Should the finished building differ from the drawings or the contract, the buyer keeps contractual and RERA remedies. Those comparing launches around Whitefield may request the sanctioned plan when they ask for the price list.

Effect on resale

With time the scheme should shift part of the older stock into the group that lenders finance without fuss. Gains go only to buildings that complete the process, so each home's papers still decide. Our team is on the contact page to go over the documents of a property you are considering.
